This paper reviews the application of tranexamic acid, an antifibrinolytic, to trauma. CRASH-2, a large randomized controlled trial, was the first to show a reduction in mortality and recommend tranexamic acid use in bleeding trauma patients. However, this paper was not without controversy. Its patient recruitment, methodology, and conductance in moderate-to-low income countries cast doubt on its ability to be applied to trauma protocols in countries with mature trauma networks. In addition to traditional vetting in scientific, peer-reviewed journals, CRASH-2 came about at a time when advances in communication technology allowed debate and influence to be leveraged in new forms, specifically through the use of multimedia campaigns, social media, and Internet blogs. This paper presents a comprehensive view of tranexamic acid utilization in trauma from peer-reviewed evidence to novel multimedia influences. PMID:26448897

An approach to transfusion and hemorrhage in trauma: current perspectives on restrictive transfusion strategies

2007-01-01

Hemorrhagic shock is a leading cause of death in trauma patients. Surgical control of bleeding and fluid resuscitation with both crystalloid and blood products remain the mainstay of therapy for injured patients with bleeding. However, there has been a recent re-evaluation of transfusion practice. Both the fear of transmissible disease and the costs of transfusing blood products have led to increasingly restrictive transfusion practices. A small percentage of trauma patients require massive transfusion. These patients are complex and difficult to manage, and clinicians must act quickly to save them. There is little evidence to help guide clinical transfusion decisions in these patients. A rational approach to using blood products requires an understanding of the end points of resuscitation. Resuscitation with fluids and red cells is necessary to improve perfusion and oxygen delivery to tissues. Avoiding overtransfusion is key, however, because transfusion is also associated with significant risks. This trend toward reducing allogenic blood exposure will likely continue. New technologies that have the potential of reducing blood loss and transfusion requirements in trauma patients with massive bleeding are being developed, and similar old technologies are being reapplied.

Multiscale systems biology of trauma-induced coagulopathy.

Trauma with hypovolemic shock is an extreme pathological state that challenges the body to maintain blood pressure and oxygenation in the face of hemorrhagic blood loss. In conjunction with surgical actions and transfusion therapy, survival requires the patient's blood to maintain hemostasis to stop bleeding. The physics of the problem are multiscale: (a) the systemic circulation sets the global blood pressure in response to blood loss and resuscitation therapy, (b) local tissue perfusion is altered by localized vasoregulatory mechanisms and bleeding, and (c) altered blood and vessel biology resulting from the trauma as well as local hemodynamics control the assembly of clotting components at the site of injury. Building upon ongoing modeling efforts to simulate arterial or venous thrombosis in a diseased vasculature, computer simulation of trauma-induced coagulopathy is an emerging approach to understand patient risk and predict response. Despite uncertainties in quantifying the patient's dynamic injury burden, multiscale systems biology may help link blood biochemistry at the molecular level to multiorgan responses in the bleeding patient. As an important goal of systems modeling, establishing early metrics of a patient's high-dimensional trajectory may help guide transfusion therapy or warn of subsequent later stage bleeding or thrombotic risks.

Tranexamic acid can reduce bleeding in patients undergoing elective surgery. We assessed the effects of early administration of a short course of tranexamic acid on death, vascular occlusive events, and the receipt of blood transfusion in trauma patients. This randomised controlled trial was undertaken in 274 hospitals in 40 countries. 20 211 adult trauma patients with, or at risk of, significant bleeding were randomly assigned within 8 h of injury to either tranexamic acid (loading dose 1 g over 10 min then infusion of 1 g over 8 h) or matching placebo. Randomisation was balanced by centre, with an allocation sequence based on a block size of eight, generated with a computer random number generator. Both participants and study staff (site investigators and trial coordinating centre staff) were masked to treatment allocation. The primary outcome was death in hospital within 4 weeks of injury, and was described with the following categories: bleeding, vascular occlusion (myocardial infarction, stroke and pulmonary embolism), multiorgan failure, head injury, and other. All analyses were by intention to treat. This study is registered as ISRCTN86750102, Clinicaltrials.govNCT00375258, and South African Clinical Trial RegisterDOH-27-0607-1919. 10 096 patients were allocated to tranexamic acid and 10 115 to placebo, of whom 10 060 and 10 067, respectively, were analysed. All-cause mortality was significantly reduced with tranexamic acid (1463 [14.5%] tranexamic acid group vs 1613 [16.0%] placebo group; relative risk 0.91, 95% CI 0.85-0.97; p=0.0035). The risk of death due to bleeding was significantly reduced (489 [4.9%] vs 574 [5.7%]; relative risk 0.85, 95% CI 0.76-0.96; p=0.0077). Tranexamic acid safely reduced the risk of death in bleeding trauma patients in this study. On the basis of these results, tranexamic acid should be considered for use in bleeding trauma patients.

Recombinant factor VII (rFVII) is an attractive agent to control refractory, coagulopathic bleeding in patients following major surgery. The purpose of this review is to evaluate the published experiences of rFVII in adult, nonhemophilic, surgical and trauma patients. A computerized literature search was conducted to identify articles pertaining to rFVII use for refractory bleeding in adult, nonhemophilic, surgical patients. The selected articles were reviewed and the applicable data was analyzed. A total of 117 patients were found in 8 case series and 24 case reports. Overall, rFVII was effective in restoring hemostasis in 99/117 (85%) patients with 76/99 (77%) surviving to hospital discharge. In trauma patients, hemostasis was achieved in 20/26 (77%) patients and 17/20 (85%) survived. There were 5 (4%) thromboembolic events observed in the 117 cases and much disparity was noted with the initial dose. Severe acidosis affected the activity of rFVII. Recombinant factor VII is an effective therapeutic agent for achieving hemostasis in nonhemophilic surgical patients. Published clinical experiences, however, are limited to small case series and case reports.

Liver transplantation has been reported in the literature as an extreme intervention in cases of severe and complicated hepatic trauma. The main indications for liver transplant in such cases were uncontrollable bleeding and postoperative hepatic insufficiency. We here describe four cases of orthotopic liver transplantation after penetrating or blunt liver trauma. The indications were liver failure, extended liver necrosis, liver gangrene and multiple episodes of gastrointestinal bleeding related to portal hypertension, respectively. One patient died due to postoperative cerebral edema. The other three patients recovered well and remain on immunosuppression. Liver transplantation should be considered as a saving procedure in severe hepatic trauma, when all other treatment modalities fail. PMID:19340909

To determine computerized tomography (CT) use and prevalence of traumatic intracranial hemorrhage (ICH) in children with and without congenital and acquired bleeding disorders. We compared CT use and ICH prevalence in children with and without bleeding disorders in a multicenter cohort study of 43 904 children <18 years old with blunt head trauma evaluated in 25 emergency departments. A total of 230 children had bleeding disorders; all had Glasgow Coma Scale (GCS) scores of 14 to 15. These children had higher CT rates than children without bleeding disorders and GCS scores of 14 to 15 (risk ratio, 2.29; 95% CI, 2.15 to 2.44). Of the children who underwent imaging with CT, 2 of 186 children with bleeding disorders had ICH (1.1%; 95% CI, 0.1 to 3.8) , compared with 655 of 14 969 children without bleeding disorders (4.4%; 95% CI, 4.1-4.7; rate ratio, 0.25; 95% CI, 0.06 to 0.98). Both children with bleeding disorders and ICHs had symptoms; none of the children required neurosurgery. In children with head trauma, CTs are obtained twice as often in children with bleeding disorders, although ICHs occurred in only 1.1%, and these patients had symptoms. Routine CT imaging after head trauma may not be required in children without symptoms who have congenital and acquired bleeding disorders. Copyright © 2011 Mosby, Inc. All rights reserved.

Angiographic embolization (AE) as an adjunct non-operative treatment of intrahepatic arterial bleeding has been widely used. The present study aimed to evaluate the efficacy of selective AE in patients with hepatic trauma. Seventy patients with intrahepatic arterial bleeding after blunt abdominal trauma who had undergone selective AE in 10 years at this institution were retrospectively reviewed. The criteria for selective AE included active extravasation on contrast-enhanced CT, an episode of hypotension or a decrease in hemoglobin level during the non-operative treatment. The data of the patients included demographics, grade of liver injuries, mechanism of blunt abdominal trauma, associated intra-abdominal injuries, indications for AE, angiographic findings, type of AE, and AE-related hepatobiliary complications. In the 70 patients, 32 (45.71%) had high-grade liver injuries. Extravazation during the early arterial phase mainly involved the right hepatic segments. Thirteen (18.57%) patients underwent embolization of intrahepatic branches and the extrahepatic trunk and these patients all developed AE-related hepatobiliary complications. In 19 patients with AE-related complications, 14 received minimally invasive treatment and recovered without severe sequelae. AE is an adjunct treatment for liver injuries. Selective and/or super-selective AE should be advocated to decrease the incidence and severity of AE-related hepatobiliary complications.

Traumatic brain injury (TBI) and hemorrhagic shock due to uncontrolled bleeding are the major causes of death after severe trauma. Mortality rates are threefold higher in patients suffering from multiple injuries and additionally TBI. Factors known to impair outcome after TBI, namely hypotension, hypoxia, hypercapnia, acidosis, coagulopathy and hypothermia are aggravated by the extent and severity of extracerebral injuries. The mainstays of TBI intensive care may be, at least temporarily, contradictory to the trauma care concept for multiple trauma patients. In particular, achieving normotension in uncontrolled bleeding situations, maintenance of normocapnia in traumatic lung injury and thromboembolic prophylaxis are prone to discussion. Due to an ongoing uncertainty about the definition of normotensive blood pressure values, a cerebral perfusion pressure-guided cardiovascular management is of key importance. In contrast, there is no doubt that early goal directed coagulation management improves outcome in patients with TBI and multiple trauma. The timing of subsequent surgical interventions must be based on the development of TBI pathology; therefore, intensive care of multiple trauma patients with TBI requires an ongoing and close cooperation between intensivists and trauma surgeons in order to individualize patient care.

Focused assessment with sonography for trauma (FAST) has become commonplace in the management of blunt abdominal trauma. However, newer computed tomography (CT) scanners have decreased imaging time for trauma patients and provide more detailed examination of abdominal contents. It was the aim of the current study to evaluate practice patterns of FAST and abdominal CT in blunt trauma victims. This was a retrospective study of all blunt trauma patients (N = 299) who received at least 1 FAST examination in the emergency department by surgeons and were admitted. Patients were tracked for subsequent CT scanning, disposition from the emergency department, any operative findings, and survival. Twenty-one of 299 patients (7%) had a positive FAST. There were 7 deaths and 14 patients were taken directly to the operating room (OR) for control of abdominal bleeding. Thirty-one of 299 (10%) had equivocal FAST. There were 4 deaths and 8 patients were taken to the OR for control of abdominal bleeding. A total of 247 of the 299 patients had a negative FAST. CT scans were performed in 193: 15 showed a visceral injury. There were 13 deaths and 29 patients were taken to the OR (4 for bleeding). Patients with a positive FAST had a higher mortality than FAST-negative patients (P < .001) and greater likelihood for operation (P < .001). Those with equivocal FAST had a greater likelihood for operation than FAST-negative patients (P < .05). FAST examinations can identify patients at risk for hemorrhage and in whom operation may be needed and, therefore, can guide mobilization of hospital resources. FAST-negative patients can be managed expectantly, using more specific imaging techniques.

Purpose: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. Methods: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. Wemore » evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. Results: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4-63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. Conclusions: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.« less

Guidelines for the use of recombinant activated factor VII (rFVIIa) in uncontrolled bleeding: a report by the Israeli Multidisciplinary rFVIIa Task Force.

Martinowitz, U; Michaelson, M

Recombinant activated factor VII (rFVIIa) has been approved by the U.S. Food and Drug Administration (FDA) for almost a decade for hemophilic patients with inhibitors. Its off-label use as a hemostatic agent in massive bleeding caused by a wide array of clinical scenarios is rapidly expanding. While evidence-based guidelines exist for rFVIIa treatment in hemophilia, none are available for its off-label use. The aim of this study is to develop expert recommendations for the use of rFVIIa in patients suffering from uncontrolled bleeding (with special emphasis on trauma) until randomized, controlled trials allow for the introduction of more established evidence-based guidelines. A multidisciplinary task force comprising representatives of the relevant National Medical Associations, experts from the Medical Corps of the Army, Ministry of Health and the Israel National Trauma Advisory Board was established in Israel. Recommendations were construed based on the analysis of the first 36 multi-trauma patients accumulated in the prospective national registry of the use of rFVIIa in trauma, and an extensive literature search consisting of published and prepublished controlled animal trials, case reports and series. The final consensus guidelines, together with the data of the first 36 trauma patients treated in Israel, are presented in this article. Results of the first 36 trauma patients: The prolonged clotting assays [prothrombin time (PT) and partial thromboplastin time (PTT)] shortened significantly within minutes following administration of rFVIIa. Cessation of bleeding was achieved in 26 of 36 (72%) patients. Acidosis diminished the hemostatic effect of the drug, while hypothermia did not affect it. The survival rate of 61% (22/36) seems to be favorable compared with published series of similar, or less severe, trauma patients (range 30%-57%). As a result of the lack of controlled trials, our guidelines should be considered as suggestive rather than conclusive. However, they provide a valuable tool for physicians using rFVIIa for the expanding off-label clinical uses.

To determine the relationship between multidetector computed tomography (MDCT) findings, management strategies, and ultimate clinical outcomes in patients with splenic injuries secondary to blunt trauma. This Institutional Review Board-approved study collected 351 consecutive patients admitted at the Emergency Department (ED) of a Level I Trauma Center with blunt splenic trauma between October 2002 and November 2015. Their MDCT studies were retrospectively and independently reviewed by two radiologists to grade splenic injuries according to the American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) and to detect intraparenchymal (type A) or extraparenchymal (type B) active bleeding and/or contained vascular injuries (CVI). Clinical data, information on management, and outcome were retrieved from the hospital database. Statistical analysis relied on Student's t, chi-squared, and Cohen's kappa tests. Emergency multiphase MDCT was obtained in 263 hemodynamically stable patients. Interobserver agreement for both AAST grading of injuries and vascular lesions was excellent (k = 0.77). Operative management (OM) was performed in 160 patients (45.58% of the whole cohort), and high-grade (IV and V) OIS injuries and type B bleeding were statistically significant (p < 0.05) predictors of OM. Nonoperative management (NOM) failed in 23 patients out of 191 (12.04%). In 75% of them, NOM failure occurred within 30 h from the trauma event, without significant increase of mortality. Both intraparenchymal and extraparenchymal active bleeding were predictive of NOM failure (p < 0.05). Providing detection and characterization of parenchymal and vascular traumatic lesions, MDCT plays a crucial role for safe and appropriate guidance of ED management of splenic traumas and contributes to the shift toward NOM in hemodynamically stable patients.

The aim of the CRASH-2 trial was to assess the effects of early administration of tranexamic acid on death, vascular occlusive events, and blood transfusion in trauma patients with significant haemorrhage. Tranexamic acid significantly reduced all-cause mortality. Because tranexamic acid is thought to exert its effect through inhibition of fibrinolysis, we undertook exploratory analyses of its effect on death due to bleeding. The CRASH-2 trial was undertaken in 274 hospitals in 40 countries. 20,211 adult trauma patients with, or at risk of, significant bleeding were randomly assigned within 8 h of injury to either tranexamic acid (loading dose 1 g over 10 min followed by infusion of 1 g over 8 h) or placebo. Patients were randomly assigned by selection of the lowest numbered treatment pack from a box containing eight numbered packs that were identical apart from the pack number. Both participants and study staff (site investigators and trial coordinating centre staff ) were masked to treatment allocation. We examined the effect of tranexamic acid on death due to bleeding according to time to treatment, severity of haemorrhage as assessed by systolic blood pressure, Glasgow coma score (GCS), and type of injury. All analyses were by intention to treat. The trial is registered as ISRCTN86750102, ClinicalTrials.gov NCT00375258, and South African Clinical Trial Register/Department of Health DOH-27-0607-1919. 10,096 patients were allocated to tranexamic acid and 10,115 to placebo, of whom 10,060 and 10,067, respectively, were analysed. 1063 deaths (35%) were due to bleeding. We recorded strong evidence that the effect of tranexamic acid on death due to bleeding varied according to the time from injury to treatment (test for interaction p<0.0001). Early treatment (≤1 h from injury) significantly reduced the risk of death due to bleeding (198/3747 [5.3%] events in tranexamic acid group vs 286/3704 [7.7%] in placebo group; relative risk [RR] 0.68, 95% CI 0.57-0.82; p<0.0001). Treatment given between 1 and 3 h also reduced the risk of death due to bleeding (147/3037 [4.8%] vs 184/2996 [6.1%]; RR 0.79, 0.64-0.97; p=0.03). Treatment given after 3 h seemed to increase the risk of death due to bleeding (144/3272 [4.4%] vs 103/3362 [3.1%]; RR 1.44, 1.12-1.84; p=0.004). We recorded no evidence that the effect of tranexamic acid on death due to bleeding varied by systolic blood pressure, Glasgow coma score, or type of injury. Tranexamic acid should be given as early as possible to bleeding trauma patients. For trauma patients admitted late after injury, tranexamic acid is less effective and could be harmful.

The objective was to clarify the role of hepatic arterial embolization (AE) in the management of blunt hepatic trauma. Retrospective observational study of 183 patients with blunt hepatic trauma admitted to a trauma referral center over a 9-year period. The charts of 29 patients (16%) who underwent hepatic angiography were reviewed for demographics, injury specific data, management strategy, angiographic indication, efficacy and complications of embolization, and outcome. AE was performed in 23 (79%) of the patients requiring angiography. Thirteen patients managed conservatively underwent emergency embolization after preliminary computed tomography scan. Six had postoperative embolization after damage control laparotomy and four had delayed embolization. Arterial bleeding was controlled in all the cases. Sixteen patients (70%) had one or more liver-related complications; temporary biliary leak (n=11), intra-abdominal hypertension (n=14), inflammatory peritonitis (n=3), hepatic necrosis (n=3), gallbladder infarction (n=2), and compressive subcapsular hematoma (n=1). Unrecognized hepatic necrosis could have contributed to the late posttraumatic death of one patient. AE is a key element in modern management of high-grade liver injuries. Two principal indications exist in the acute postinjury phase: primary hemostatic control in hemodynamically stable or stabilized patients with radiologic computed tomography evidence of active arterial bleeding and adjunctive hemostatic control in patients with uncontrolled suspected arterial bleeding despite emergency laparotomy. Successful management of injuries of grade III upward often entails a combined angiographic and surgical approach. Awareness of the ischemic complications due to angioembolization is important.

This study aimed to determine any association between positive findings in ultrasonography examination and initial BD value with regard to diagnosis of intra-abdominal bleeding following blunt abdominal trauma. A prospective, multi-center study of consecutive adult patients was performed from April to September 2015. Demographics, initial vital signs and arterial BD were evaluated with respect to presence of any association with intra-abdominal bleeding and in-hospital mortality. FAST study was performed to find intra-abdominal bleeding. Receiver operating characteristic (ROC) curves tested the ability of BD to identify patients with intra-abdominal hemorrhage and probable mortality. A total of 879 patients were included in final analysis. The mean (SD) age was 36.68 (15.7) years and 714 patients (81.2%) were male. According to multivariable analysis, statistically significant association was observed between negative admission BD and both intra-abdominal bleeding (OR 3.48, 95% CI 2.06-5.88, p<0.001) and in-hospital mortality (OR 1.55, 95% CI 1.49-1.63, p<0.001). ROC curve analysis demonstrated sensitivity of 92.7% and specificity of 22.1% for the best cut-off value of BD (-8mEq/L) to diagnose internal hemorrhage. Further, a cut-off value of -7mEq/L demonstrated significant predictive performance, 94.8% sensitivity and 53.6% specificity for in-hospital mortality. This study revealed that arterial BD is an early accessible important marker to identify intra-abdominal bleeding, as well as to predict overall in-hospital mortality in patients with blunt abdominal trauma.

In trauma research, "massive transfusion" (MT), historically defined as receiving ≥10 units of red blood cells (RBCs) within 24 h of admission, has been routinely used as a "gold standard" for quantifying bleeding severity. Due to early in-hospital mortality, however, MT is subject to survivor bias and thus a poorly defined criterion to classify bleeding trauma patients. Using the data from a retrospective trauma transfusion study, we applied a latent-class (LC) mixture model to identify severely hemorrhaging (SH) patients. Based on the joint distribution of cumulative units of RBCs and binary survival outcome at 24 h of admission, we applied an expectation-maximization (EM) algorithm to obtain model parameters. Estimated posterior probabilities were used for patients' classification and compared with the MT rule. To evaluate predictive performance of the LC-based classification, we examined the role of six clinical variables as predictors using two separate logistic regression models. Out of 471 trauma patients, 211 (45 %) were MT, while our latent SH classifier identified only 127 (27 %) of patients as SH. The agreement between the two classification methods was 73 %. A non-ignorable portion of patients (17 out of 68, 25 %) who died within 24 h were not classified as MT but the SH group included 62 patients (91 %) who died during the same period. Our comparison of the predictive models based on MT and SH revealed significant differences between the coefficients of potential predictors of patients who may be in need of activation of the massive transfusion protocol. The traditional MT classification does not adequately reflect transfusion practices and outcomes during the trauma reception and initial resuscitation phase. Although we have demonstrated that joint latent class modeling could be used to correct for potential bias caused by misclassification of severely bleeding patients, improvement in this approach could be made in the presence of time to event data from prospective studies.

The management of trauma patients suffering from active bleeding has improved with a better understanding of trauma-induced coagulopathy. The aim of this manuscript is to give recommendations for coagulation management. A systematic literature search in the PubMed database was performed for articles published between January 2000 and August 2009. A total of 230 articles were included in the present systematic review. The "coagulopathy of trauma" is a discrete disease which has a decisive influence on survival. Diagnosis and therapy of deranged coagulation should start immediately after admission to the emergency department. A specific protocol for massive transfusion should be introduced and continued. Loss of body temperature should be prevented and treated. Acidaemia should be prevented and treated by appropriate shock therapy. If massive transfusion is performed using fresh frozen plasma (FFP), a ratio of FFP to pRBC (packed red blood cells) of 1:2-1:1 should be achieved. Fibrinogen should be substituted at levels of <1.5 g/L. For patients suffering from active bleeding, permissive hypotension (i.e. mean arterial pressure ~65 mmHg) may be aimed for until surgical cessation of bleeding. This option is contraindicated in injuries of the central nervous system and in patients with coronary heart disease, or with known hypertension. Thrombelastography or -metry may be performed to guide coagulation diagnosis and substitution. Hypocalcaemia <0.9 mmol/L should be avoided and may be treated. For actively bleeding patients, pRBC may be given at haemoglobin <10 g/L (6.2 mmol/L) and haematocrit may be targeted at 30%.

Early detection and management of post-traumatic haemorrhage and coagulopathy have been associated with improved outcomes, but local infrastructures, logistics and clinical strategies may differ. To assess local differences in infrastructure, logistics and clinical management of trauma-associated haemorrhage and coagulopathy, we have conducted a web-based survey amongst the delegates to the 15th European Congress of Trauma and Emergency Surgery (ECTES) and the 2nd World Trauma (WT) Congress held in Frankfurt, Germany, 25-27 May 2014. 446/1,540 delegates completed the questionnaire yielding a response rate of 29%. The majority specified to work as consultants/senior physicians (47.3%) in general (36.1%) or trauma/orthopaedic surgery (44.5%) of level I (70%) or level II (19%) trauma centres. Clinical assessment (>80%) and standard coagulation assays (74.6%) are the most frequently used strategies for early detection and monitoring of bleeding trauma patients with coagulopathy. Only 30% of the respondents declared to use extended coagulation assays to better characterise the bleeding and coagulopathy prompted by more individualised treatment concepts. Most trauma centres (69%) have implemented local protocols based on international and national guidelines using conventional blood products, e.g. packed red blood cell concentrates (93.3%), fresh frozen plasma concentrates (93.3%) and platelet concentrates (83%), and antifibrinolytics (100%). 89% considered the continuous intake of anticoagulants including "new oral anticoagulants" and platelet inhibitors as an increasing threat to bleeding trauma patients. This study confirms differences in infrastructure, logistics and clinical practice for the detection and management of trauma-haemorrhage and trauma-associated coagulopathy amongst international centres. Ongoing work will focus on geographical differences.

Spontaneous or idiopathic intramedullary bleeding is a very rare event in pediatric patients. This diagnosis requires an extended clinical, laboratory, and radiologic work-up to rule out all potential causes of hematomyelia. However, children may present with hematomyelia or spinal cord injury without radiographic abnormality even after a minor trauma. A 15-month-old girl presented with a 24-hour history of progressive neurologic deficits. A trivial trauma had occurred a few days before the clinical onset. Head computed tomography scan and craniospinal magnetic resonance imaging revealed an isolated hemorrhagic central medullary lesion extending from the obex to C3 level. No underlying causes of intramedullary bleeding were identified. In the absence of obvious vascular abnormalities, the patient underwent an urgent occipitocervical decompression with hematoma evacuation. Postoperatively, the patient's motor symptoms rapidly resolved, and she was discharged with cervical collar immobilization. We discuss the differential diagnosis of intramedullary bleeding in children, focusing on the diagnostic protocol and therapeutic options in this age group. Copyright © 2016 Elsevier Inc.

EndoVascular and Hybrid Trauma Management (EVTM) is an emerging concept for the early treatment of trauma patients using aortic balloon occlusion (ABO), embolization agents and stent grafts to stop ongoing traumatic bleeding. These techniques have previously been implemented successfully in the treatment of ruptured aortic aneurysm. We describe our very recent experience of EVTM using ABO in bleeding patients and lessons learned over the last 20 years from the endovascular treatment of ruptured abdominal aortic aneurysms (rAAA). We also briefly describe current knowledge of ABO usage in trauma. A small series of educational cases in our hospital is described, where endovascular techniques were used to gain temporary hemorrhage control. The methods used for rAAA and their applicability to EVTM with a multidisciplinary approach are presented. Establishing femoral arterial access immediately on arrival at the emergency room and use of an angiography table in the surgical suite may facilitate EVTM at an early stage. ABO may be an effective method for the temporary stabilization of severely hemodynamically unstable patients with hemorrhagic shock, and may be useful as a bridge to definitive treatment of the bleeding patients. EVTM, including the usage of ABO, can be initiated on patient arrival and is feasible. Further data need to be collected to investigate proper indications for ABO, best clinical usage, results and potential complications. Accordingly, the ABOTrauma Registry has recently been set up. Existing experiences of EVTM and lessons from the endovascular treatment of rAAA may be useful in trauma management.

Despite the use of evidence-based platelet transfusion therapy during periods of hypoproliferative thrombocytopenia, a large proportion of pediatric hematology/oncology patients continue to suffer from clinically significant bleeding. Antifibrinolytic (AF) drugs have been shown in certain surgical and trauma settings to decrease bleeding, blood transfusion, and improve survival. We conducted a retrospective assessment of the safety of using AF drugs in pediatric patients with hypoproliferative thrombocytopenia at our center as well as the impact on bleeding occurrence and severity. © 2017 Wiley Periodicals, Inc.

Physiological parameters are crucial for the caring of trauma patients. There is a significant loss of prehospital vital signs data of patients during handover between prehospital and in-hospital teams. Effective strategies for reducing the loss remain a challenging research area. We tested whether the newly developed electronic automated prehospital vital signs chart sharing system would increase the amount of prehospital vital signs data shared with a remote trauma center prior to hospital arrival. Fifty trauma patients, transferred to a level I trauma center in Japan, were studied. The primary outcome variable was the number of prehospital vital signs shared with the trauma center prior to hospital arrival. The prehospital vital signs chart sharing system significantly increased the number of prehospital vital signs, including blood pressure, heart rate, and oxygen saturation, shared with the in-hospital team at a remote trauma center prior to patient arrival at the hospital (P < .0001). There were significant differences in prehospital vital signs during ambulance transfer between patients who had severe bleeding and non-severe bleeding within 24 hours after injury onset. Vital signs data collected during ambulance transfer via patient monitors could be automatically converted to easily visible patient charts and effectively shared with the remote trauma center prior to hospital arrival. The prehospital vital signs chart sharing system increased the number of precise vital signs shared prior to patient arrival at the hospital, which can potentially contribute to better trauma care without increasing labor and reduce information loss during clinical handover.

Conventional methods for hemorrhage control in the trauma patient fall short of providing a full solution for the life-threatening bleeding injury. The tourniquet is limited specifically to injuries of the distal limbs. Local pressure or tight bandaging with military bandages is cumbersome and often insufficient. Therefore, we sought a superior method to stop bleeding in emergency situations. Our objective is report and description of our experience with this method. Since 1992 our trauma team repeatedly encountered multiple trauma victims presenting with bleeding wounds. We achieved hemorrhage control by means of an adhesive elastic bandage applied directly over a collection of 4 x 4 gauze pads placed on the wound surface. The roll is then wrapped around the body surface, over the bleeding site, until sufficient pressure is reached to terminate ongoing hemorrhage. Three typical cases are described in detail. Adhesive elastic dressing compression was successful in fully controlling bleeding without compromise of distal blood flow. Our method corresponded to the demand for an immediate, effective and lasting form of hemorrhage control without complications. Furthermore, this technique proved successful even over body surfaces normally recognized as difficult to compress. We experienced equal favorable success while working during transit by either ambulance or helicopter transportation. We find our preliminary experience using elastic adhesive dressing for bleeding control encouraging and suggest that this may substitute existing practices as the selected treatment when indicated. This method is presently underrecognized for this purpose. Development of a single unit bandage may further enhance success in the future.

The aim of this study was to examine the clinical characteristics of dental emergency patients who visited a university hospital emergency center and to evaluate the incidence of dental trauma. A retrospective chart review of patients with dental complaints and who visited the Seoul National University Bundang Hospital (SNUBH) emergency center in Gyeonggi-do, Korea, from January 2009 to December 2009 was conducted. Information regarding age, gender, the time, day, and month of presentation, diagnosis, treatment, and follow up was collected and analyzed. One thousand four hundred twenty-five patients with dental problems visited the SNUBH emergency center. Dental patients accounted for 1.47% of the total 96,708 patients at the emergency center. The male-to-female ratio was 1.68:1, with a considerably larger number of male patients (62.7%). The age distribution peak was at 0-9 years (27.5%), followed by patients in their forties (14.1%). The number of patients visiting the dental emergency center peaked in May (14.2%), on Sundays (22.4%), and between 2100 and 2400 h (20.8%). The patients' chief complaints were as follows: dental trauma, dental infection, oral bleeding, and temporomandibular joint disorder (TMD). The prevalence of dental trauma was 66%. The reasons for dental emergency visits included the following: dental trauma, dental infection, oral bleeding, and TMD, with 66% of the patients requiring management of dental trauma. It is important that dentists make a prompt, accurate diagnosis and initiate effective treatment in case of dental emergencies, especially dental trauma. © 2011 John Wiley & Sons A/S.

Introduction Intestinal obstruction following abdominal trauma has previously been described. However, in most reported cases pathological finding was intestinal stenosis. Presentation of the case A 51-year-old male was admitted after a motor vehicle accident. Initial focused abdominal sonogram for trauma and enhanced computerized tomography were normal, however there was a fracture of the tibia. Three days later, he complained of abdominal pain, constipation, and vomiting. An exploratory laparotomy showed bleeding from the omentum and mechanical small bowel obstruction due to a fibrous band. Discussion The patient had prior abdominal surgery, but clinical and radiological findings indicate that the impact of the motor vehicle accident initiated his condition either by causing rotation of a bowel segment around the fibrous band, or by formation of a fibrous band secondary to minimal bleeding from the omentum. Conclusion High index of suspicion of intestinal obstruction is mandatory in trauma patients presenting with complaints of abdominal pain, vomiting, and constipation despite uneventful CT scan.

Update on massive transfusion.

PubMed

Pham, H P; Shaz, B H

Massive haemorrhage requires massive transfusion (MT) to maintain adequate circulation and haemostasis. For optimal management of massively bleeding patients, regardless of aetiology (trauma, obstetrical, surgical), effective preparation and communication between transfusion and other laboratory services and clinical teams are essential. A well-defined MT protocol is a valuable tool to delineate how blood products are ordered, prepared, and delivered; determine laboratory algorithms to use as transfusion guidelines; and outline duties and facilitate communication between involved personnel. In MT patients, it is crucial to practice damage control resuscitation and to administer blood products early in the resuscitation. Trauma patients are often admitted with early trauma-induced coagulopathy (ETIC), which is associated with mortality; the aetiology of ETIC is likely multifactorial. Current data support that trauma patients treated with higher ratios of plasma and platelet to red blood cell transfusions have improved outcomes, but further clinical investigation is needed. Additionally, tranexamic acid has been shown to decrease the mortality in trauma patients requiring MT. Greater use of cryoprecipitate or fibrinogen concentrate might be beneficial in MT patients from obstetrical causes. The risks and benefits for other therapies (prothrombin complex concentrate, recombinant activated factor VII, or whole blood) are not clearly defined in MT patients. Throughout the resuscitation, the patient should be closely monitored and both metabolic and coagulation abnormalities corrected. Further studies are needed to clarify the optimal ratios of blood products, treatment based on underlying clinical disorder, use of alternative therapies, and integration of laboratory testing results in the management of massively bleeding patients.

To evaluate efficacy and safety of a novel device that combines an inferior vena cava (IVC) filter and central venous catheter (CVC) for prevention of pulmonary embolism (PE) in critically ill patients. In a multicenter, prospective, single-arm clinical trial, the device was inserted at the bedside without fluoroscopy and subsequently retrieved before transfer from the intensive care unit (ICU). The primary efficacy endpoint was freedom from clinically significant PE or fatal PE 72 hours after device removal or discharge, whichever occurred first. Secondary endpoints were incidence of acute proximal deep venous thrombosis (DVT), catheter-related thrombosis, catheter-related bloodstream infections, major bleeding events, and clinically significant thrombus (occupying > 25% of volume of filter) detected by cavography before retrieval. The device was placed in 163 critically ill patients with contraindications to anticoagulation; 151 (93%) were critically ill trauma patients, 129 (85%) had head or spine trauma, and 102 (79%) had intracranial bleeding. The primary efficacy endpoint was achieved for all 163 (100%) patients (95% confidence interval [CI], 97.8%-100%, P < .01). Diagnosis of new or worsening acute proximal DVT was time dependent with 11 (7%) occurring during the first 7 days. There were no (0%) catheter-related bloodstream infections. There were 5 (3.1%) major bleeding events. Significant thrombus in the IVC filter occurred in 14 (8.6%) patients. Prophylactic anticoagulation was not initiated for a mean of 5.5 days ± 4.3 after ICU admission. This novel device prevented clinically significant and fatal PE among critically ill trauma patients with low risk of complications. Copyright © 2017 SIR. Published by Elsevier Inc.

Management of bleeding and coagulopathy following major trauma: an updated European guideline

PubMed Central

2013-01-01

Introduction Evidence-based recommendations are needed to guide the acute management of the bleeding trauma patient. When these recommendations are implemented patient outcomes may be improved. Methods The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing a guideline for the management of bleeding following severe injury. This document represents an updated version of the guideline published by the group in 2007 and updated in 2010. Recommendations were formulated using a nominal group process, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) hierarchy of evidence and based on a systematic review of published literature. Results Key changes encompassed in this version of the guideline include new recommendations on the appropriate use of vasopressors and inotropic agents, and reflect an awareness of the growing number of patients in the population at large treated with antiplatelet agents and/or oral anticoagulants. The current guideline also includes recommendations and a discussion of thromboprophylactic strategies for all patients following traumatic injury. The most significant addition is a new section that discusses the need for every institution to develop, implement and adhere to an evidence-based clinical protocol to manage traumatically injured patients. The remaining recommendations have been re-evaluated and graded based on literature published since the last edition of the guideline. Consideration was also given to changes in clinical practice that have taken place during this time period as a result of both new evidence and changes in the general availability of relevant agents and technologies. Conclusions A comprehensive, multidisciplinary approach to trauma care and mechanisms with which to ensure that established protocols are consistently implemented will ensure a uniform and high standard of care across Europe and beyond.

2014-01-01

Hepatic pseudoaneurysm is rare and potentially fatal. It occurs as a consequence of injury to the vascular wall, erosion diathermy through clips, biliary leakage and secondary infection. The main symptom is intra-abdominal bleeding. To communicate the case of two patients with hepatic pseudoaneurysm. Case 1: We present a 43 year-old male with a history of grade IV liver injury due to blunt abdominal trauma and managed surgically. Case 2: A 67 year-old man with bile duct injury after laparoscopic cholecystectomy. Both patients presented with biliary leakage, abdominal sepsis and late intra-abdominal bleeding. Tomographic studies showed the lesion. Superselective embolization was performed proximal and distal to the lesion with good results. During follow-up, none of them showed signs of recurrent bleeding. Hepatic artery pseudoaneurysm is rare and usually secondary to bile duct injury associated with vascular injury after cholecystectomy or liver trauma. Arteriography with embolization is the best diagnostic and therapeutic procedure. Surgery is indicated for hemodynamically unstable patients, embolization failure or rebleeding. Early diagnosis reduces morbidity and mortality of this complication.

Trauma patients with uncontrolled hemorrhage encountering coagulopathy are often associated with poor outcome. Recently, the concept of damage control interventional radiology, which focuses on "speedy stoppage of bleeding" by interventional radiology among trauma patients with hemodynamic instability and acute traumatic coagulopathy, was proposed as an alternative to damage control surgery. N-butyl cyanoacrylate (NBCA) has been used as a liquid embolic agent in various non-traumatic situations, where it has been shown to have a high technical success rate and low recurrent bleeding rate, especially in patients with coagulopathy. In this case, we treated a young patient with hemodynamic instability caused by a high-grade hepatic injury, who underwent arterial embolization (AE) using NBCA assisted with resuscitative endovascular balloon occlusion of the aorta and achieved successful hemostasis. A review of published works using PUBMED was carried out, and 10 published reports involving 23 trauma patients who underwent AE using NBCA were identified. Among them, only four reports involving five trauma patients with torso visceral injuries were identified. Three of five patients who were hemodynamically unstable underwent AE using NBCA, resulting in the stabilization of hemodynamics. We concluded that AE with resuscitative endovascular balloon occlusion of the aorta as a damage control interventional radiology procedure might be acceptable for the hemodynamically unstable hepatic injury, and NBCA could be one of the effective hemostatic agents for this purpose, in cases of trauma-induced coagulopathy.

Randomized clinical trial of ligasure™ versus conventional splenectomy for injured spleen in blunt abdominal trauma.

Spleen is the most common organ damaged in cases of blunt abdominal trauma and splenectomy and splenorrhaphy are the main surgical procedures that are used in surgical treatment of such cases. In routine open splenectomy cases, after laparotomy, application of sutures in splenic vasculature is the most widely used procedure to cease the bleeding. This clinical trial evaluates the role and benefits of the Ligasure™ system in traumatic splenectomy without using any suture materials and compares the result with conventional method of splenectomy. After making decision for splenectomy secondary to a blunt abdominal trauma, patients in control group (39) underwent splenectomy using conventional method with silk suture ligation of splenic vasculature. In the interventional group (41) a Ligasure™ vascular sealing system was used for ligating of the splenic vein and artery. The results of operation time, volume of intra-operation bleeding and post-operative complications were compared in both groups. The mean operation times in control and interventional group were 21 and 12 min respectively (p < 0.05). The average volume of bleeding in control group during open splenectomy was 280 cc, but in the interventional group decreased significantly to 80 ml (p < 0.05) using the Ligasure system. Post-operative complications such as bleeding were non-existent in both groups. The application of Ligasure™ in blunt abdominal trauma for splenectomy not only can decrease the operation time but also can decrease the volume of bleeding during operation without any additional increase in post-operative complications. This method is recommendable in traumatic splenic injuries that require splenectomy in order to control the bleeding as opposed to use of traditional silk sutures.

Wilson, Stephen J; Bellamy, Mark C; Giannoudis, Peter V

2005-05-01

Recombinant activated Factor VII (rFVIIa) has been successfully used in the treatment of haemophilia A and B with associated inhibitors for some years. Activated Factor VII binds to activated platelets independently of tissue factor. The resulting stimulation of an exaggerated early thrombin burst at sites of vascular injury makes it an attractive potential treatment for massive, uncontrolled bleeding associated with surgery and trauma. This article describes the evidence relating to surgery and trauma. The lack of large, controlled trials of rFVIIa means that a definitive recommendation regarding its use cannot be made at present. However, in the context of clearly defined protocols and balanced treatment strategies, rFVIIa may have a role in traumatic bleeding. Large scale, randomised controlled trials in trauma are required, as is further work on the safety profile of rFVIIa with an independent international safety monitoring committee.

Hypothermia is an independent predictor of mortality in adult trauma studies. However, the impact of hypothermia on the pediatric trauma population has not been described. The purpose of this study is to evaluate hypothermia as a cofactor to mortality, complications, and among survivors, hospital length of stay parameters in the pediatric trauma population. Retrospective review of a prospectively collected database (National Trauma Registry of the American College of Surgeons) over a 5-yr period (July 2002 to June 2007). A rural, level I trauma center. One thousand six hundred twenty-nine pediatric patients admitted with a traumatic injury. None. Multivariate regression models were used to evaluate the association of hypothermia with mortality, infectious complications, organ dysfunction, and among survivors, hospital length of stay parameters. Of 1,629 pediatric trauma patients admitted, 182 (11.1%) patients were hypothermic (temperature below 36 degrees C) on admission. Hypothermia had an adjusted odds ratio (AOR) of 2.41 (95% confidence interval [CI], 1.12-5.22, p = .025) for mortality. After controlling for covariates, hypothermia had associations with developing pneumonia (AOR, 0.185, 95% CI, 0.040-0.853; p = .031) and a bleeding diathesis (AOR, 3.14, 95% CI, 1.04-9.44; p = .042). The median days in the hospital, intensive care unit (ICU), and ventilator were longer in the hypothermic cohort; however, after controlling for covariates, hypothermia was not associated with differences in hospital days, ICU days, or ventilator days. Hypothermia is a common problem at admission among pediatric trauma patients. Hypothermia is associated with an increase in the odds of death and the development of a bleeding diathesis, while having decreased odds for developing pneumonia. While the length of stay indicators were longer in the hypothermic cohort among survivors, no significant association was noted with hypothermia for hospital, ICU, or ventilator days after controlling for confounders.

Pelvic Arterial Embolisation in a Trauma Patient with a Pre-Existing Aortobifemoral Graft

Pelvic fractures secondary to blunt trauma are associated with a significant mortality rate due to uncontrolled bleeding. Interventional radiology (IR) can play an important and central role in the management of such patients, offering definitive minimally invasive therapy and avoiding the need for high-risk surgery. Rapid access to whole-body computed tomography has been shown to improve survival in polytrauma patients and allows rapid diagnosis of vascular injury and assessment of suitability for endovascular therapy. IR can then target and treat the specific area of bleeding. Embolisation of bleeding pelvic arteries has been shown to be highly effective and should bemore » the treatment of choice in this situation. The branches of the internal iliac artery (IIA) are usually involved, and these arteries are accessed by way of IIA catheterisation after abdominal aortography. Occasionally these arteries cannot be accessed by way of this conventional route because of recent IIA ligation carried out surgically in an attempt to stop the bleeding or because (in the rare situation we describe here) these vessels are excluded secondary to previous aortoiliac repair. In this situation, knowledge of pelvic arterial collateral artery pathways is important because these will continue to supply pelvic structures whilst making access to deep pelvic branches challenging. We describe a rare case, which has not been previously reported in the literature, in which successful embolisation of a bleeding pelvic artery was carried out by way of the collateral artery pathways.« less

Coagulation management in trauma-associated coagulopathy: allogenic blood products versus coagulation factor concentrates in trauma care.

PubMed

Klages, Matthias; Zacharowski, Kai; Weber, Christian Friedrich

2016-04-01

Coagulation management by transfusion of allogenic blood products and coagulation factors are competing concepts in current trauma care. Rapid and adequate therapy of trauma-associated coagulopathy is crucial to survival of severely injured patients. Standard coagulation tests such as prothrombin time and activated partial thromboplastin time are commonly used, but these tests are inappropriate for monitoring and guiding therapy in trauma patients. Coagulation factor-based treatment showed promising results, but randomized trials have not yet been performed. In addition, viscoelastic tests are needed to guide therapy, although there is in fact limited evidence for these in tests in trauma care. Regarding transfusion therapy with allogenic blood products, plasma transfusion has been associated with improved survival in trauma patients following massive transfusion. In contrast, patients not requiring massive transfusion seem to be at risk for suffering complications with increasing volumes of plasma transfused. The collective of trauma patients is heterogeneous. Despite the lack of evidence, there are strong arguments for individualized patient treatment with coagulation factors for some indications and to abstain from the use of fresh frozen plasma. In patients with severe trauma and major bleeding, plasma, platelets, and red blood cells should be considered to be administered at a ratio of 1 : 1 : 1.

Over the last decade the age of trauma patients and injury mortality has increased. At the same time, many centers have implemented multiple interventions focused on improved hemorrhage control, effectively resulting in a bleeding control bundle of care. The objective of our study was to analyze the temporal distribution of trauma-related deaths, the factors that characterize that distribution and how those factors have changed over time at our urban level 1 trauma center. Records at an urban Level 1 trauma center were reviewed. Two time periods (2005-2006 and 2012-2013) were included in the analysis. Mortality rates were directly adjusted for age, gender and mechanism of injury. The Mann-Whitney and chi square tests were used to compare variables between periods, with significance set at 0.05. 7080 patients (498 deaths) were examined in 2005-2006, while 8767 patients (531 deaths) were reviewed in 2012-2013. The median age increased 6 years, with a similar increase in those who died. In patients that died, no differences by gender, race or ethnicity were observed. Fall-related deaths are now the leading cause of death. Traumatic brain injury (TBI) and hemorrhage accounted for >91% of all deaths. TBI (61%) and multiple organ failure or sepsis (6.2%) deaths were unchanged, while deaths associated with hemorrhage decreased from 36% to 25% (p<0.01). Across time periods, 26% of all deaths occurred within one hour of hospital arrival, while 59% occurred within 24h. Unadjusted mortality dropped from 7.0% to 6.1 (p=0.01) and in-hospital mortality dropped from 6.0% to 5.0% (p<0.01). Adjusted mortality dropped 24% from 7.6% (95% CI: 6.9-8.2) to 5.8% (95% CI: 5.3-6.3) and in-hospital mortality decreased 30% from 6.6% (95% CI: 6.0-7.2) to 4.7 (95% CI: 4.2-5.1). Over the same time frame of this study, increases in trauma death across the globe have been reported. This single-site study demonstrated a significant reduction in mortality, attributable to decreased hemorrhagic death. It is possible that efforts focused on hemorrhage control interventions (a bleeding control bundle) resulted in this reduction. These changing factors provide guidance on future prevention and intervention efforts. Copyright © 2016 Elsevier Ltd. All rights reserved.

Initiation and Termination of Massive Transfusion Protocols: Current Strategies and Future Prospects.

Foster, John C; Sappenfield, Joshua W; Smith, Robert S; Kiley, Sean P

2017-12-01

The advent of massive transfusion protocols (MTP) has had a significant positive impact on hemorrhaging trauma patient morbidity and mortality. Nevertheless, societal MTP guidelines and individual MTPs at academic institutions continue to circulate opposing recommendations on topics critical to MTPs. This narrative review discusses up-to-date information on 2 such topics, the initiation and termination of an MTP. The discussion for each begins with a review of the recommendations and supporting literature presented by MTP guidelines from 3 prominent societies, the American Society of Anesthesiologists, the American College of Surgeons, and the task force for Advanced Bleeding Care in Trauma. This is followed by an in-depth analysis of the main components within those recommendations. Societal recommendations on MTP initiation in hemorrhaging trauma patients emphasize the use of retrospectively validated massive transfusion (MT) prediction score, specifically, the Assessment of Blood Consumption and Trauma-Associated Severe Hemorrhage scores. Validation studies have shown that both scoring systems perform similarly. Both scores reliably identify patients that will not require an MT, while simultaneously overpredicting MT requirements. However, each scoring system has its unique advantages and disadvantages, and this review discusses how specific aspects of each scoring system can affect widespread applicability and statistical performance. In addition, we discuss the often overlooked topic of initiating MT in nontrauma patients and the specific tools physicians have to guide the MT initiation decision in this unique setting. Despite the serious complications that can arise with transfusion of large volumes of blood products, there is considerably less research pertinent to the topic of MTP termination. Societal recommendations on MTP termination emphasize applying clinical reasoning to identify patients who have bleeding source control and are adequately resuscitated. This review, however, focuses primarily on the recommendations presented by the Advanced Bleeding Care in Trauma's MTP guidelines that call for prompt termination of the algorithm-guided model of resuscitation and rapidly transitioning into a resuscitation model guided by laboratory test results. We also discuss the evidence in support of laboratory result-guided resuscitation and how recent literature on viscoelastic hemostatic assays, although limited, highlights the potential to achieve additional benefits from this method of resuscitation.

A common national MTP was jointly implemented in 2011 by the national blood service (Blood Services Group) and seven participating acute hospitals to provide rapid access to transfusion support for massively haemorrhaging patients treated in all acute care hospitals. Through a systematic clinical workflow, blood components are transfused in a ratio of 1:1:1 (pRBC: whole blood-derived platelets: FFP), together with cryoprecipitate for fibrinogen replacement. The composition of components for the MTP is fixed, although operational aspects of the MTP can be adapted by individual hospitals to suit local hospital workflow. The MTP could be activated in support of any patient with critical bleeding and at risk of massive transfusion, including trauma and non-trauma general medical, surgical and obstetric patients. There were 434 activations of the MTP from October 2011 to October 2013. Thirty-nine per cent were for trauma patients, and 30% were for surgical patients with heavy intra-operative bleeding, with 25% and 6% for patients with gastrointestinal bleeding and peri-partum haemorrhage, respectively. Several hospitals reported reduction in mean time between request and arrival of blood. Mean transfusion ratio achieved was one red cell unit: 0·8 FFP units: 0·8 whole blood-derived platelet units: 0·4 units of cryoprecipitate. Although cryoprecipitate usage more than doubled after introduction of MTP, there was no significant rise in overall red cells, platelet and FFP usage following implementation. This successful collaboration shows that shared transfusion protocols are feasible and potentially advantageous for hospitals sharing a central blood provider. © 2015 International Society of Blood Transfusion.

Atraumatic acute carpal tunnel syndrome in a patient taking dabigatran.

Sibley, Paul A; Mandel, Richard J

2012-08-01

Acute carpal tunnel syndrome is an uncommon diagnosis most often related to blunt trauma requiring immediate surgical decompression to avoid serious sequelae. Patients who present with bleeding-related acute carpal tunnel syndrome tend to have severe pain, rapid onset of swelling, and neurologic symptoms that appear early and progress rapidly secondary to mass effect. Acute carpal tunnel syndrome can occur in anticoagulated patients spontaneously or after minor trauma. This article describes a case of a 57-year-old man with progressive pain and paresthesias in the median nerve distribution after reaching for a picture frame. He was taking dabigatran, a direct thrombin inhibitor, for atrial fibrillation. He developed acute carpal tunnel syndrome secondary to spontaneous bleeding into the carpal canal and flexor tenosynovium with hematoma formation requiring surgical decompression. He reported immediate pain relief postoperatively, had no further bleeding complications, and regained full median nerve function within 2 months.Dabigatran has gained recent popularity for the treatment of atrial fibrillation. Unlike warfarin, its use does not involve regular laboratory monitoring or dose titration. The risks and benefits of dabigatran should be considered carefully by the prescriber, particularly in patients taking medications that may alter its metabolism. Aspirin and nonsteroidal anti-inflammatory drugs may have effects similar to dabigatran and may increase the risk of bleeding problems. Should acute carpal tunnel syndrome occur, the authors recommend prompt surgical decompression rather than conservative management. The modification of anticoagulant therapy should be considered on a case-by-case basis. Copyright 2012, SLACK Incorporated.

Early resuscitation intensity as a surrogate for bleeding severity and early mortality in the PRospective, Observational, Multicenter, Major Trauma Transfusion (PROMMTT) Study

Background The classic definition of MT, ≥10 units red blood cells (RBCs) in 24 hours, has never been demonstrated as a valid surrogate for severe hemorrhage and can introduce survival bias. In addition, the definition fails to capture other products that the clinician may have immediately available during the initial resuscitation. Assuming that units of resuscitative fluids reflect patient illness, our objective was to identify a rate of resuscitation intensity (RI) that could serve as an early surrogate of sickness for patients with substantial bleeding post-injury. Methods Adult patients surviving at least 30 minutes post-admission and receiving ≥1 RBC within 6 hours of admission from ten US Level 1 trauma centers were enrolled in the PRospective Observational Multicenter Major Trauma Transfusion study. Total fluid units were calculated as the sum of the number of crystalloid units (1 L=1 unit), colloids (0.5 L=1 unit) and blood products (1 RBC=1 unit, 1 plasma=1 unit, 6 pack platelets=1 unit). Univariable and multivariable logistic regressions were used to evaluate associations between RI and 6-hour mortality, adjusting for age, center, penetrating injury, weighted Revised Trauma Score, and Injury Severity Score. Results 1096 eligible patients received resuscitative fluids within 30 minutes, including 620 transfused with blood products. Despite varying products utilized, the total fluid RI was similar across all sites (3.2±2.5 units). Patients who received ≥4 units of any resuscitative fluid had a 6-hour mortality rate of 14.4% vs. 4.5% in patients who received <4 units. The adjusted odds ratio of 6-hour mortality for patients receiving ≥4 units within 30 minutes was 2.1 (95% Confidence Interval: 1.2–3.5). Conclusions Resuscitation with ≥4 units of any fluid was significantly associated with 6-hour mortality. This study suggests that early RI regardless of fluid type can be used as a surrogate for sickness and mortality in severely bleeding patients.

Plasma transfusion for patients with severe hemorrhage: what is the evidence?

Callum, Jeannie L; Rizoli, Sandro

2012-05-01

The following review will detail the current knowledge in massive hemorrhage with regard to the pathophysiology of the coagulation disturbance, the role of plasma, the role of alternatives to plasma, and the clinical value of having a massive transfusion protocol. The coagulation disturbance in trauma patients is more than just the result of consumption of clotting factors at sites of injury and dilution from the infusion of intravenous fluids and red blood cells (RBCs). Even before substantial amounts of fluid resuscitation and RBC transfusion, one-quarter of trauma patients already have abnormal coagulation variables. There is an apparent role for the activation of protein C, hypofibrinogenemia, and fibrin(gen)olysis in the coagulation disturbance after trauma and massive hemorrhage. None of these three disturbances would be completely mitigated by the use of plasma alone, suggesting that there may be an opportunity to improve care of these patients with alternative strategies, such as fibrinogen concentrates and antifibrinolytics. Despite numerous retrospective cohort studies evaluating 1:1 plasma to RBC formula-driven resuscitation, the overall clinical value of this approach is unclear. Studies have even raised concerns regarding a potential increase in morbidity associated with this approach, particularly for patients overtriaged to 1:1 where a massive transfusion is unlikely. We also do not have sufficient evidence to recommend either goal-directed therapy with thromboelastography or early use of fibrinogen replacement, with either cryoprecipitate or fibrinogen concentrates. We have high-quality data that argue against the role for recombinant Factor VIIa that should prompt removal of this strategy from existing protocols. In contrast, we have high-level evidence that all bleeding trauma patients should receive tranexamic acid as soon as possible after injury. This therapy must be included in hemorrhage protocols. If we are to improve the care of massively bleeding patients on a firm scientific ground, we will need large-scale randomized trials to delineate the role of coagulation replacement and the utility of laboratory monitoring. But even until these trials are completed, it is clear that a massive transfusion protocol is needed in all hospitals that manage bleeding patients, to ensure a prompt and coordinated response to hemorrhage. © 2012 American Association of Blood Banks.

Abdominopelvic trauma (APT) remains a leading cause of morbidity and mortality in the 15- to 44-year-old age group in the Western World. It can be life-threatening as abdominopelvic organs, specifically those in the retroperitoneal space, can bleed profusely. APT is divided into blunt and penetrating types. While surgery is notably considered as a definitive solution for bleeding control, it is not always the optimum treatment for the stabilization of a polytrauma patient. Over the past decades, there has been a shift toward more sophisticated strategies, such as non-operative management of abdominopelvic vascular trauma for haemodynamically stable patients. Angiographic embolization for bleeding control following blunt and/or penetrating intra- and retroperitoneal injuries has proven to be safe and effective. Embolization can achieve hemostasis and salvage organs without the morbidity of surgery, and the development and refinement of embolization techniques has widened the indications for non-operative treatment in solid organ injury. Moreover, advances in computed tomography provided more efficient scanning times with improved image quality. While surgery is still usually recommended for patients with penetrating injuries, non-operative management can be effectively used as well as an alternative treatment. We review indications, technical considerations, efficacy, and complication rates of angiographic embolization in APT. PMID:28824919

Venous thromboembolism is a cause of morbidity and mortality in trauma patients. Chemoprophylaxis with low-molecular-weight heparin at a standardized dose is recommended. Conventional chemoprophylaxis may be inadequate. We hypothesized that a weight-adjusted enoxaparin prophylaxis regimen would reduce the frequency of venous thromboembolism in hospitalized trauma patients and at 90-day follow-up. This prospective, randomized pilot study enrolled adult patients admitted to a level 1 trauma center between July 2013 and January 2015. Subjects were randomized to receive either standard (30 mg subcutaneously every 12 hours) or weight-based (0.5mg/kg subcutaneously every 12 hours) enoxaparin. Surveillance duplex ultrasound for lower extremity deep vein thrombosis was performed on hospital days 1, 3, and 7, and weekly thereafter. The primary outcome was deep vein thrombosis during hospitalization. Secondary outcomes included venous thromboembolism at 90 days and significant bleeding events. Two hundred thirty-four (124 standard, 110 weight-based) subjects were enrolled. There was no difference between standard and weight-based regarding age, body mass index, percentage female gender, injury severity score, or percentage that had surgery. There was a trend toward less in-hospital deep vein thrombosis in weight-based (12 [9.7%] standard vs 4 [3.6%] weight-based, P = .075). At 90 days, there was no difference in venous thromboembolism (12 [9.7%] standard vs 6 [5.5%] weight-based, P =.34). There was 1 bleeding event, which occurred in a standard subject. Weight-based enoxaparin dosing for venous thromboembolism chemoprophylaxis in trauma patients may provide better protection against venous thromboembolism than standard. A definitive study is necessary to determine whether weight-based dosing is superior to standard. Copyright © 2018 Elsevier Inc. All rights reserved.

The ability to easily predict the need for massive transfusion may improve the process of care, allowing early mobilization of resources. There are currently no clear criteria to activate massive transfusion in severely injured trauma patients. The aims of this study were to create a scoring system to predict the need for massive transfusion and then to validate this scoring system. We reviewed the records of 119 severely injured trauma patients and identified massive transfusion predictors using statistical methods. Each predictor was converted into a simple score based on the odds ratio in a multivariate logistic regression analysis. The Traumatic Bleeding Severity Score (TBSS) was defined as the sum of the component scores. The predictive value of the TBSS for massive transfusion was then validated, using data from 113 severely injured trauma patients. Receiver operating characteristic curve analysis was performed to compare the results of TBSS with the Trauma-Associated Severe Hemorrhage score and the Assessment of Blood Consumption score. In the development phase, five predictors of massive transfusion were identified, including age, systolic blood pressure, the Focused Assessment with Sonography for Trauma scan, severity of pelvic fracture, and lactate level. The maximum TBSS is 57 points. In the validation study, the average TBSS in patients who received massive transfusion was significantly greater (24.2 [6.7]) than the score of patients who did not (6.2 [4.7]) (p < 0.01). The area under the receiver operating characteristic curve, sensitivity, and specificity for a TBSS greater than 15 points was 0.985 (significantly higher than the other scoring systems evaluated at 0.892 and 0.813, respectively), 97.4%, and 96.2%, respectively. The TBSS is simple to calculate using an available iOS application and is accurate in predicting the need for massive transfusion. Additional multicenter studies are needed to further validate this scoring system and further assess its utility. Prognostic study, level III.

The evaluation and management of patients with abdominal vascular trauma or injury requires immediate and effective decision-making in these unfavorable circumstances. The majority of these patients arrive at trauma centers in profound shock, secondary to massive blood loss, which is often unrelenting. Moreover, ischemia, compartment syndrome, thrombosis, and embolization may also be life threatening and require immediate intervention. To minimize the risk of these potentially lethal complications, early understanding of the disease process and emergent therapeutic intervention are necessary. In the literature, the management of acute traumatic vascular injuries is restricted to traditional open surgical techniques. However, in penetrating injuries surgeons often face a potentially contaminated field, which renders the placement of prosthetic grafts inappropriate. Currently, however, there are sparse data on the management of vascular trauma with endovascular techniques. The role of endovascular technique in penetrating abdominal vascular trauma, which is almost always associated with severe active bleeding, is limited. It is worth mentioning that hybrid operating rooms with angiographic radiology capabilities offer more opportunities for the management of this kind of injuries by either temporary control of the devastating bleeding using endovascular balloon tamponade or with embolization and stenting. On the other hand, blunt abdominal injuries are less dangerous and they could be treated at most times by endovascular means. Since surgeons continue to encounter abdominal vascular trauma, open and endovascular techniques will evolve constantly giving us encouraging messages for the near future. PMID:29516005

Airway management through submental derivation: a safe and easily reproduced alternative for patients with complex facial trauma

PubMed Central

2018-01-01

Objectives Airway management in patients with panfacial trauma is complicated. In addition to involving facial lesions, such trauma compromises the airway, and the use of intermaxillary fixation makes it difficult to secure ventilation by usual approaches (nasotracheal or endotracheal intubation). Submental airway derivation is an alternative to tracheostomy and nasotracheal intubation, allowing a permeable airway with minimal complications in complex patients. Materials and Methods This is a descriptive, retrospective study based on a review of medical records of all patients with facial trauma from January 2003 to May 2015. In total, 31 patients with complex factures requiring submental airway derivation were included. No complications such as bleeding, infection, vascular, glandular, or nervous lesions were presented in any of the patients. Results The use of submental airway derivation is a simple, safe, and easy method to ensure airway management. Moreover, it allows an easier reconstruction. Conclusion Based on these results, we concluded that, if the relevant steps are followed, the use of submental intubation in the treatment of patients with complex facial trauma is a safe and effective option.

The aim of the study is to describe the epidemiology of major bleeding fatalities. A case series analysis of Australia's National Coronial Information System was conducted. Keywords were used to search for closed cases of major haemorrhage in the state of Victoria for the period 1 January 2009 to 31 December 2011. Coroners' findings, autopsy reports and police reports of cases were reviewed. Demographic data were extracted, and cases were assigned to a clinical bleeding context. A total of 427 cases of major bleeding causing death were identified. The cohort was predominately men (69%), with a median age of 63 years (interquartile range 45-77 years). Trauma accounted for 38%, gastrointestinal haemorrhage 28%, surgical/procedural bleeding 14%, ruptured/leaking aneurysms 12% and other 8%. Most events began in homes (46%), hospitals (22%) and at the roadside (17%). Of those whose haemorrhage began in the community, 69% did not survive to hospital. Major bleeding fatalities occurred across a diverse range of contexts, with trauma and gastrointestinal bleeding accounting for most deaths. The majority of patients did not survive to reach hospital. Major haemorrhage occurring entirely outside hospital may be underrecognised from analyses of datasets based primarily on traumatic or in-hospital bleeding. These findings have implications for management of pre-hospital resuscitation and development of clinical practice guidelines for identification and management of major bleeding in the community. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Rational development of technology for rapid control of noncompressible torso hemorrhage (NCTH) requires detailed understanding of what is bleeding. Our objectives were to describe the anatomic location of truncal bleeding in patients presenting with NCTH and compare endovascular (ENDO) management versus open (OPEN) management. This is a retrospective study of adult trauma patients with NCTH admitted to four urban Level I trauma centers in the Houston and San Antonio metropolitan areas in 2008 to 2012. Inclusion criteria include named axial torso vessel disruption, Abbreviated Injury Scale chest or abdomen score of 3 or higher with shock (base excess, <-4) or truncal operation in 90 minutes or less, or pelvic fracture with ring disruption. Exclusion criteria include isolated hip fractures, falls from standing, or prehospital cardiopulmonary resuscitation. After dichotomizing into OPEN, ENDO, and resuscitative thoracotomy (RT) groups based on the initial approach to control NCTH, a mixed-effects Poisson regression with robust error variance (controlling for age, mechanism, Injury Severity Score, shock, hypotension, and severe head injury as fixed effects and site as a random effect) was used to test the hypothesis that ENDO was associated with reduced in-hospital mortality in NCTH patients. Five hundred forty-three patients with NCTH underwent ENDO (n = 166, 31%), OPEN (n = 309, 57%), or RT (n = 68, 12%). Anatomic bleeding locations were 25% chest, 41% abdomen, and 31% pelvis. ENDO was used to treat relatively few types of vascular injuries, whereas OPEN and RT injuries were more diverse. ENDO patients had more blunt trauma (95% vs. 34% vs. 32%); severe injuries (median Injury Severity Score, 34 vs. 27 vs. 21), and increased time to intervention (median, 298 vs. 92 vs. 51 minutes) compared with OPEN and RT. Mortality was 15% versus 20% versus 79%. ENDO was associated with decreased mortality compared to OPEN (relative risk, 0.58; 95% confidence interval, 0.46-0.73). Although ENDO may reduce mortality in NCTH patients, significant group differences limit the generalizability of this finding. Therapeutic, level V.

2005-01-01

Acute compartment syndrome of the thigh is a rare condition, and the basic causes of high pressure within a muscle compartment have been considered to be intramuscular haematoma and soft-tissue oedema. However, the importance of arterial injury has not been well recognized. Among 3658 blunt trauma patients admitted to our Level 1 Trauma Centre between 1994 and 2001, there were eight patients (nine thighs) who had undergone emergency fasciotomy and these were the subjects of the present study. Arteriography of the proximal lower limb had been performed after the fasciotomy in patients with prolonged hypotension and persistent bleeding from the fasciotomy wound. All the patients had sustained high-energy trauma, systemic hypotension and local trauma to the proximal lower limb. Among them, four (five thighs) had undergone arteriography and four (four thighs) were confirmed as having sustained arterial injuries. In those patients with definitive arterial injuries, the time from injury to the onset of the compartment syndrome was less than 5 h. Acute compartment syndrome of the thigh in blunt trauma patients may be the result of associated arterial injuries. It is suggested that patients with local trauma to the proximal lower limb who exhibit an acute compartment syndrome together with haemodynamic instability should undergo arteriography soon after fasciotomy.

We report 2 successful treatment cases of renal artery occlusion (RAO) related to multiple trauma. A 4-year-old boy was diagnosed with right RAO and liver laceration after a traffic accident. Surgical thrombectomy and revascularization were performed, but the lacerated liver was not sutured. The lacerated liver was surgically repaired 6 days post operation because of delayed bleeding. Thirteen percent of the patient's right kidney function was conserved. Another 7-year-old boy was compressed by an agitator. Renal scintigraphy showed that the right kidney was nonfunctional. The patient underwent conservative observation without any complication. In stable patients with multiple trauma, RAO should be diagnosed as soon as possible. Copyright © 2016 Elsevier Inc.

Reports on venous trauma are relatively sparse. Severe venous trauma is manifested by hemorrhage, not ischemia. Bleeding may be internal or external and rarely may lead to hypovolemic shock. Repair of major extremity veins has been a subject of controversy and the current teaching is to avoid venous repair in an unstable or multi-trauma patient. The aim of the current paper is to present our recent experience in major venous trauma during the Lebanon conflict, means of diagnosis and treatment in a level I trauma center. All cases of major venous trauma, either isolated or combined with arterial injury, admitted to the emergency room during the 33-day conflict were reviewed. Out of 511 wounded soldiers and civilians who were admitted to our service over this period, 12 (2.3%) sustained a penetrating venous injury either isolated (5) or combined with arterial injury (7). All injuries were secondary to high velocity penetrating missiles or from multiple pellets stored in long-range missiles. All injuries were accompanied by additional insult to soft tissue, bone and viscera. The mean injury severity score was 15. Severe external bleeding was the presenting symptom in three cases of isolated venous injury (jugular, popliteal and femoral). The diagnosis of a major venous injury was made by a CTA scan in five cases, angiography in one and during surgical exploration in six cases. All injured veins were repaired: three by venous interposition grafts, four by end to end anastomosis, three by lateral suture and two by endovascular techniques. None of the injuries was treated by ligation of a major named vein. Immediate postoperative course was uneventful in all patients and the 30-day follow-up (by clinical assessment and duplex scan) has demonstrated a patent repair with no evidence of thrombosis. Without contradicting the wisdom of ligating major veins in the setup of multi-trauma or an unstable patient, our experience indicates that a routine repair of venous trauma can be safely and effectively performed in young patients. Postoperative course is not compromised and late sequelae of venous interruption may be prevented.

The aim of this study was to assess the lifetime cost effectiveness of recombinant activated factor VII vs placebo as adjunctive therapy for control of bleeding in patients with severe blunt trauma in the UK. We developed a cost-effectiveness model based on patient level data from a 30-day international, randomised, placebo-controlled Phase II trial. The data were supplemented with secondary data from UK sources to estimate lifetime costs and benefits. The model produced a baseline estimate of the incremental cost per life year gained with recombinant activated factor VII relative to placebo of 12 613 UK pounds. The incremental cost per quality adjusted life year gained was 18 825 UK pounds. These estimates are sensitive to the choice of discount rate and health state utility values used. Preliminary results suggest that relative to placebo, recombinant activated factor VII may be a cost-effective therapy to the UK National Health Service.

Hypothermia in bleeding trauma: a friend or a foe?

PubMed Central

2009-01-01

The induction of hypothermia for cellular protection is well established in several clinical settings. Its role in trauma patients, however, is controversial. This review discusses the benefits and complications of induced hypothermia--emphasizing the current state of knowledge and potential applications in bleeding patients. Extensive pre-clinical data suggest that in advanced stages of shock, rapid cooling can protect cells during ischemia and reperfusion, decrease organ damage, and improve survival. Yet hypothermia is a double edged sword; unless carefully managed, its induction can be associated with a number of complications. Appropriate patient selection requires a thorough understanding of the pre-clinical literature. Clinicians must also appreciate the enormous influence that temperature modulation exerts on various cellular mechanisms. This manuscript aims to provide a balanced view of the published literature on this topic. While many of the advantageous molecular and physiological effects of induced hypothermia have been outlined in animal models, rigorous clinical investigations are needed to translate these promising findings into clinical practice.

Immediate angiography is warranted in pelvic trauma patients with suspected arterial injury (AI) in order to stop ongoing bleeding. Prior to angiography, plain pelvic radiography (PPR) and abdominopelvic computer tomography (CT) are performed to identify fracture and hematoma sites. To investigate if PPR and CT can identify the location of AI in trauma patients undergoing angiography. 95 patients with pelvic fractures on PPR (29 women, 66 men), at a mean age of 44 (9-92) years, underwent pelvic angiography for suspected AI. Fifty-six of them underwent CT additionally. Right and left anterior and posterior fractures on PPR were registered, and fracture displacement was recorded for each quadrant. Arterial blush on CT was registered, and the size of the hematoma in each region was measured in cm(2). AIs were registered for anterior and posterior segments of both internal iliac arteries. Presence of fractures, arterial blush, and hematomas were correlated with AI. Presence of fracture in the corresponding skeletal segment on PPR showed sensitivity and specificity of 0.86 and 0.58 posteriorly, and 0.87 and 0.44 anteriorly. The area under the curve (AUC) was 0.77 and 0.69, respectively. Fracture displacement on PPR >0.9 cm posteriorly and >1.9 cm anteriorly revealed specificity of 0.84. Sensitivities of arterial blush and hematoma on CT were 0.38 and 0.82 posteriorly, and 0.24 and 0.82 anteriorly. The specificities were 0.96 and 0.58 posteriorly, and 0.79 and 0.53 anteriorly, respectively. For hematomas, the AUC was 0.79 posteriorly and 0.75 anteriorly. Size of hematoma >22 cm(2) posteriorly and >29 cm(2) anteriorly revealed specificity of 0.85 and 0.86, respectively. CT findings of arterial blush and hematoma predicted site of arterial bleeding on pelvic angiography. Also, PPR predicted the site of bleeding using location of fracture and size of displacement. In the hemodynamically unstable patient, PPR may contribute equally to effective assessment of injured arteries.

Blunt abdominal trauma is much more frequent than penetrating abdominal trauma in Europe. As a consequence of improved quality of computed tomography, even complex liver injuries are increasingly being treated conservatively. However, missed hollow viscus injuries still remain a problem, as they considerably increase mortality in multiply injured patients. Laparoscopy decreases the rate of unnecessary laparotomies in perforating abdominal trauma and helps to diagnose injuries of solid organs and the diaphragm. However, the sensitivity in detecting hollow viscus injuries is low and the role of laparoscopy in blunt abdominal injury has not been defined. If intra-abdominal bleeding is difficult to control in hemodynamically unstable patients, damage control surgery with packing of the liver, total splenectomy, and provisional closure of hollow viscus injuries is of importance. Definitive surgical treatment follows hemodynamic stabilization and restoration of hemostasis. Injuries of the duodenum and pancreas after blunt abdominal trauma are often associated with other intra-abdominal injuries and the treatment depends on their location and severity.

The aim of this study is to evaluate the diagnostic criteria, treatment options and progression of cases who have antenatal or postpartum hemorrhage due to internal myometrial laceration (IML) and to review the literature. The files of eight patients who were diagnosed to have IML between August 2012 and July 2015 were evaluated retrospectively. The patient group consisted of four patients who had an emergency c-section due to massive bleeding during labor and four patients who had an emergency laparotomy due to uncontrolled bleeding after vaginal delivery after evaluation of the patient for signs of 4Ts (trauma, tissue retention, uterine tonus, and trombin). Primary suturation was the first-line treatment in all patients. In two of the patients, hysterectomy was performed after the defined surgical procedures were not successful in controling the bleeding. The presented case series is a pioneering study that describes IM which is a poorly defined reason of postpartum hemorrhage, as the cause of bleeding during labor. Primary suturation is the first-step, further surgery might be required in order to treat this life-threathening condition and the decision should be based on the age and the fertility status of the patient.

Improving outcome of trauma patients by implementing patient blood management.

Füllenbach, Christoph; Zacharowski, Kai; Meybohm, Patrick

Patient blood management aims to improve patient outcome and safety by reducing the number of unnecessary red blood cell transfusions and vitalizing patient-specific anemia reserves. While this is increasingly recognized as best clinical practice in elective surgery, the implementation in the setting of trauma is restrained because of typically nonelective (emergency) surgery and, in specific circumstances, allogeneic blood transfusions as life-saving therapy. Viscoelastic diagnostics allow a precise identification of trauma-induced coagulopathy. A coagulation factor concentrate-based therapy is increasingly recognized as a fast and effective concept to correct coagulopathy and minimize blood loss. Using smaller tubes has a great potential to reduce the severity of phlebotomy-induced anemia. Washed cell salvage may reduce the number of allogeneic blood transfusions. Intravenous iron (with or without erythropoietin) may result in an increase of hemoglobin levels and reduced red blood cell transfusion requirements. Although a restrictive transfusion strategy is recommended in general, a target hemoglobin level of 7-9 g/dl is recommended in acute bleeding patients. In the setting of trauma, options to avoid unnecessary blood loss and reduce blood transfusion are manifold. These are likely to improve safety and outcome of trauma patients while potentially reducing therapeutic costs.

Extracorporeal membrane oxygenation (ECMO) may offer life-saving treatment in severe pulmonary contusion or acute respiratory distress syndrome when conventional treatments have failed. However, because of the bleeding risk of systemic anticoagulation, ECMO should be performed only as a last resort in multiple trauma victims. Here, we report ECMO as a bridge for right main bronchus reconstruction and recovery of traumatic wet lung in a 31-year-old male multi-trauma patient with right main bronchial disruption, bilateral pulmonary contusion, cerebral contusion and long bone fracture. The patient was discharged without any obvious complication. ECMO support in a traumatic brain injured patient with severe hypoxemia caused by lung contusion and/or tracheal bronchus disruption is not an absolute contraindication. © The Author(s) 2014.

Laparoscopy is increasingly utilised in the trauma setting. However, its safety and reliability in evaluating and managing retroperitoneal injuries are not known. The aim of this study was to analyse our experience with laparoscopic management of retroperitoneal injuries due to penetrating abdominal trauma (PAT) and to investigate its feasibility, safety and accuracy in haemodynamically stable patients. Over a 4-year period, patients approached laparoscopically with retroperitoneal injuries were analysed. Mechanism, location and severity of injuries were recorded. Surgical procedures, conversion rate and reasons for conversion and outcomes were described. Of the 284 patients with PAT, 56 patients had involvement of retroperitoneum. Stab wounds accounted 62.5% of patients. The mean Injury Severity Score was 7.4 (4-20). Among retroperitoneal injuries, the colon (27%) was the most commonly involved hollow viscera followed by duodenum (5%). The kidney (5%) and the pancreas (4%) were the injured solid organs. The conversion rate was 19.6% and was mainly due to active bleeding (73%). Significantly more patients with gunshot wound were converted to laparotomy (38% vs. 9%). Therapeutic laparoscopy was performed in 36% of patients. There were no recorded missed injuries or mortality. Five (9%) patients developed the Clavien-Dindo Grade 3 complications, three were managed with reoperation, one with drainage/debridement and one with endovascular technique. Laparoscopic management of retroperitoneal injuries is safe and feasible in haemodynamically stable patients with PAT. However, a high conversion rate indicates difficulties in managing these injuries. The requirements are the dexterity in laparoscopy and readiness to convert in the event of bleeding.

The specialty literature of the last decade presents the nonoperative management of the closed abdominal trauma as the treatment of choice. The purpose of this study is to highlight the importance of the optimal management of hepatic lesions considering the clinical, paraclinical and therapeutic approach. Our study is based on the analysis of the clinical and paraclinical data and also on the evaluation of the treatment results in 1671 patients with abdominal trauma affecting multiple organs who were treated at the Clinic of Surgery, County Hospital of Oradea from 2008 to 2011. The non-operative approach of the hepatic trauma, applied in 52% of the patients, was indicated in stable hemodynamic status, non-bleeding hepatic lesions on the abdominal CT, and the absence of other significant abdominal lesions. The remaining 48% were treated surgically. The postoperative evolution was free of complications in 72% of the patients while the rest of 28% presented one or more postoperative complications.

Estimating unknown parameters in haemophilia using expert judgement elicitation.

PubMed

Fischer, K; Lewandowski, D; Janssen, M P

2013-09-01

The increasing attention to healthcare costs and treatment efficiency has led to an increasing demand for quantitative data concerning patient and treatment characteristics in haemophilia. However, most of these data are difficult to obtain. The aim of this study was to use expert judgement elicitation (EJE) to estimate currently unavailable key parameters for treatment models in severe haemophilia A. Using a formal expert elicitation procedure, 19 international experts provided information on (i) natural bleeding frequency according to age and onset of bleeding, (ii) treatment of bleeds, (iii) time needed to control bleeding after starting secondary prophylaxis, (iv) dose requirements for secondary prophylaxis according to onset of bleeding, and (v) life-expectancy. For each parameter experts provided their quantitative estimates (median, P10, P90), which were combined using a graphical method. In addition, information was obtained concerning key decision parameters of haemophilia treatment. There was most agreement between experts regarding bleeding frequencies for patients treated on demand with an average onset of joint bleeding (1.7 years): median 12 joint bleeds per year (95% confidence interval 0.9-36) for patients ≤ 18, and 11 (0.8-61) for adult patients. Less agreement was observed concerning estimated effective dose for secondary prophylaxis in adults: median 2000 IU every other day The majority (63%) of experts expected that a single minor joint bleed could cause irreversible damage, and would accept up to three minor joint bleeds or one trauma related joint bleed annually on prophylaxis. Expert judgement elicitation allowed structured capturing of quantitative expert estimates. It generated novel data to be used in computer modelling, clinical care, and trial design. © 2013 John Wiley & Sons Ltd.

The management of blunt splenic injuries (BSI) has evolved toward strategies that avoid splenectomy. There is growing adoption of interventional radiology (IR) techniques in non-operative management of BSI, with evidence suggesting a corresponding reduction in emergency laparotomy requirements and increased splenic preservation rates. Currently there are no UK national guidelines for the management of blunt splenic injury. This may lead to variations in management, despite the reorganisation of trauma services in England in 2012. A survey was distributed through the British Society of Interventional Radiologists to all UK members aiming to identify availability of IR services in England, radiologists' practice, and attitudes toward management of BSI. 116 responses from respondents working in 23 of the 26 Regional Trauma Networks in England were received. 79% provide a single dedicated IR service but over 50% cover more than one hospital within the network. All offer arterial embolisation for BSI. Only 25% follow guidelines. In haemodynamically stable patients, an increasing trend for embolisation was seen as grade of splenic injury increased from 1 to 4 (12.5%-82.14%, p<0.01). In unstable patients or those with radiological evidence of bleeding, significantly more respondents offer embolisation for grade 1-3 injuries (p<0.01), compared to stable patients. Significantly fewer respondents offer embolisation for grade 5 versus 4 injuries in unstable patients or with evidence of bleeding. Splenic embolisation is offered for a variety of injury grades, providing the patient remains stable. Variation in interventional radiology services remain despite the introduction of regional trauma networks. Copyright © 2017 Elsevier Ltd. All rights reserved.

Retrievable vena cava filters in trauma patients for high-risk prophylaxis and prevention of pulmonary embolism.

2005-06-01

Venous thromboembolic (VTE) disease remains a significant cause of morbidity for trauma patients because many patients have injuries that may preclude effective VTE prevention and treatment. Retrievable vena cava filters may prove beneficial in this subset of trauma patients. Trauma patients at risk for VTE were identified and managed by institutional protocol. Patients who required a vena cava filter were managed with a device that could be retrieved or left in situ. A retrospective review of medical records was used to identify the use, indications, and complications associated with a retrievable filter. Fifty-three retrievable filters were placed in 51 patients. Two of these patients received a second filter, and 1 received a filter in the superior vena cava. Thirty-two filters were placed prophylactically, whereas 21 were placed for demonstrated venous thromboembolism (VTE). Retrieval was successful in 24 of 25 attempts. Twenty-nine filters became permanent: 10 for continued contraindications to anticoagulation without known VTE, 12 for known VTE and continued contraindications to anticoagulation, 1 for technical reasons, and 6 because of patient death. There were no complications of bleeding, device migration or thrombosis, infection, or pulmonary embolism. A retrievable vena cava filter appears safe and effective for the prevention of pulmonary embolism in the high-risk trauma patient who cannot receive anticoagulation.

Pelvic packing or angiography: competitive or complementary?

PubMed

Suzuki, Takashi; Smith, Wade R; Moore, Ernest E

2009-04-01

Pelvic angiography is an established technique that has evolved into a highly effective means of controlling arterial pelvic haemorrhage. The current dominant paradigm for haemodynamically unstable patients with pelvic fractures is angiographic management combined with mechanical stabilisation of the pelvis. However, an effective rapid screening tool for arterial bleeding in pelvic fracture patients has yet to be identified. There is also no precise way to determine the major source of bleeding responsible for haemodynamic instability. In many pelvic fracture patients, bleeding is from venous lacerations which are not effectively treated with angiography to fractured bony surfaces. Modern pelvic packing consists of time-saving and minimally invasive techniques which appear to result in effective control of the haemorrhage via tamponade. This review article focuses on the recent body of knowledge on angiography and pelvic packing. We propose the optimal role for each modality in trauma centres.

Fibrin glue as a hemostatic agent in hepatic and splenic trauma.

PubMed

Ochsner, M G; Maniscalco-Theberge, M E; Champion, H R

1990-07-01

Fibrin glue is a biologic hemostatic agent that coagulates and seals upon application. It is made by combining human fibrinogen concentrate with standard thrombin solutions containing calcium. Similar to epoxy glue, the two components are applied simultaneously in equal volumes resulting in an almost instantaneous formation of a coagulum. Fibrinogen concentrate is prepared in the blood bank from single donor plasma. Fibrin glue can be applied topically or injected into the parenchyma of solid organs. Twenty-six patients sustained hepatic or splenic trauma from May through August 1989--17 liver and nine splenic injuries. The glue was effective after one application in 21 patients and after a second in five. Hemostasis was achieved despite coagulopathy and thrombocytopenia in eight patients. There were no re-explorations for bleeding, and nine complications occurred in six patients. Our experience suggests fibrin glue is an effective, underutilized adjunctive hemostatic agent in trauma.

During the past decades, the safety of pancreatoduodenectomy has improved, with low mortality and reduced morbidity, particularly in centers with extensive experience. Emergency pancreatoduodenectomy is an uncommon event, for treatment of pancreaticoduodenal trauma, bleeding, or perforation. We herein present a single center experience concerning nontrauma emergency pancreatoduodenectomy for pancreaticoduodenal bleeding. From January 2007 to December 2015, from a population of 134 PD (70 males and 64 females, mean age 62.2, range 34-82), 5 patients (3.7%; 2 males and 3 females, mean age 64, range 57-70) underwent one-stage emergency pancreatoduodenectomy for uncontrollable nontrauma pancreaticoduodenal bleeding in our tertiary center. All the 5 patients underwent a backwards Whipple with a morbidity of 60% and a mortality of 20% (1/5). The other 4 patients were recovered and discharged with a median postoperative length of stay of 17 days (range 14-23). Emergency pancreatoduodenectomy is a definitive life-saving procedure allowing for a rapid control of bleeding when other less invasive approaches (transcatheter arterial embolization or interventional endoscopy) are exhausted, unavailable, or unsafe. It should be particularly considered in neoplastic disease and tailored by surgeons with a high level of experience in pancreatic surgery.

A fall from a standing position (FFS) is a low impact injury; however, in certain patient populations it can result in serious, complex injuries associated with significant morbidity and mortality. The purpose of the study was to identify the patient population, risk factors and outcomes of intracranial bleed (ICB) after a fall from a standing position. Data of all patients from the trauma database at State designated Trauma Center were analyzed who FFS. Patient's demography, clinical information was obtained. An ICB seen on computed tomography (CT) scan was considered positive. From January 2001 through December 2008, 163 patients admitted to the trauma center after FFS. Ninety-one out of 163 patients (56 %) had positive CT scan. There was no significant difference between the groups with a positive or negative CT regarding age (P = 0.07), gender (P = 0.58), race (P = 0.15), Glasgow Coma Scale (P = 0.27), aspirin use (P = 0.06), Plavix (P = 0.92), combination of aspirin and Plavix (P = 0.86) or use of Coumadin (P = 0.82). Patients with ICB had significantly higher injury severity score (ISS) than patients without ICB (P < 0.0001). However, the overall mortality between the groups was not significant (P = 0.66). From a multiple logistic regression model, age ≥70 years was the only predictor for the ICB. A high proportion of our patients had positive ICB due to falls from a standing position. No significant differences were seen between the groups in terms of mortality. Age ≥70 years was the only factor for positive ICB.

Evaluation and Management of Blunt Solid Organ Trauma.

Martin, Jonathan G; Shah, Jay; Robinson, Craig; Dariushnia, Sean

2017-12-01

Trauma is a leading cause of death in patients under the age of 45 and generally associated with a high kinetic energy event such as a motor vehicle accident or fall from extreme elevations. Blunt trauma can affect every organ system and major vascular structure with potentially devastating effect. When we consider abdominal solid organ injury from blunt trauma, we usually think of the liver, spleen, and kidneys. However, all of the abdominal organs, including the pancreas and adrenal glands, may be involved. Blunt hepatic trauma is more commonly associated with venous bleeding rather than arterial injury. Stable venous injury is often managed conservatively; when the patient is hemodynamically unstable from venous hepatic injury, operative management should be first-line therapy. When the injury is arterial, endovascular therapy should be initiated. Blunt trauma to the spleen is the most common cause of traumatic injury to the spleen. Management is controversial. In our institution unstable patients are taken to the operating room, and stable patients with Grades IV-V injuries and patients with active arterial injury are taken for endovascular treatment. Renal injuries are less common, and evidence of arterial injury such as active extravasation or pseudoaneurysm is warranted before endovascular therapy. Pancreatic trauma is uncommon and usually secondary to steering wheel/handlebar mechanism injuries. Adrenal injuries are rare in the absence of megatrauma or underlying adrenal abnormality.

Detection of mild inherited disorders of blood coagulation: current options and personal recommendations.

PubMed

Lippi, Giuseppe; Pasalic, Leonardo; Favaloro, Emmanuel J

2015-08-01

Although assessment of prior personal and familial bleeding history is an important aspect of the diagnosis of bleeding disorders, patients with mild inherited bleeding disorders are sometimes clinically asymptomatic until presented with a hemostatic challenge. However, bleeding may occur after incursion of trauma or surgery, so detection of these conditions reflects an important facet of clinical and laboratory practice. Mild bleeding disorders may be detected as a result of family studies or following identification of abnormal values in first-line screening tests such as activated partial thromboplastin time, prothrombin time, fibrinogen and global platelet function screen testing, such as the platelet function analyzer. Following determination of abnormal screening tests, subsequent investigation should follow a systematic approach that targets specific diagnostic tests, and including factor assays, full platelet function assays and more extensive specialized hemostasis testing. The current report provides a personal overview on inherited disorders of blood coagulation and their detection.

Background Tranexamic acid (TXA), a synthetic antifibrinolytic drug, is effective as a treatment for serious hemorrhage, including bleeding arising from major trauma and post-operative interventions. Significant acute gastrointestinal bleeding may have a poor outcome despite routine medical and endoscopic treatments. The aim of this study was to assess whether early intravenous and/or intravenous plus topical administration of TXA reduces the need for urgent endoscopy for acute gastrointestinal bleeding. Method This double-blind randomized clinical trial included 410 patients with proven acute gastrointestinal bleeding. All patients received conventional therapy. The subjects were randomized to three groups: (A) 138 patients received intravenous TXA (1 g q6h); (B) 133 patients received topical TXA (1 g single dose by nasogastric tube) plus systemic TXA; and (C) 139 patients received a placebo (sodium chloride 0.9%) for 24 hours. Subgroup statistical analyses were conducted for urgent endoscopy, mortality, re-bleeding, blood transfusion, endoscopic and/or surgical intervention rates, and health status. Results The time to endoscopy was significantly shorter in group C (15.58 ± 7.994, p < 0.001). A need for urgent endoscopy was seen in 14.49%, 10.52%, and 30.21% of patients in groups A, B, and C, respectively (p < 0.001). No significant statistical differences were seen between treatment groups regarding mortality, re-bleeding, blood transfusion, and endoscopic and/or surgical intervention rates. No thromboembolic event was documented during the 1-week follow up. Conclusions Our results showed that the antifibrinolytic properties of TXA can aid in changing an urgent endoscopy to an elective procedure, with better outcomes for both physicians and patients.

Despite the fact that treatment of liver injuries has dramatically evolved, severe liver traumas in polytraumatic patients still have a significant morbidity and mortality. The purpose of this study was to determine the options for surgical management of severe liver trauma as well as the outcome. In this retrospective study 70 polytraumatic patients with severe (American Association for the Surgery of Trauma [AAST] grade III-V) blunt liver injuries were operated on at the Clinic for Emergency Surgery. Mean age of patients was 48.26±16.80 years; 82.8% of patients were male. Road traffic accident was the leading cause of trauma, seen in 63 patients (90.0%). Primary repair was performed in 36 patients (51.4%), while damage control with perihepatic packing was done in 34 (48.6%). Complications related to the liver occurred in 14 patients (20.0%). Liver related mortality was 17.1%. Non-survivors had a significantly higher AAST grade (p=0.0001), higher aspartate aminotransferase level (p=0.01), lower hemoglobin level (p=0.0001), associated brain injury (p=0.0001), perioperative complications (p=0.001) and higher transfusion score (p=0.0001). The most common cause of mortality in the "early period" was uncontrolled bleeding, in the "late period" mortality was caused by sepsis and acute respiratory distress syndrome. Patients with high-grade liver trauma who present with hemorrhagic shock and associated severe injury should be managed operatively. Mortality from liver trauma is high for patients with higher AAST grade of injury, associated brain injury and massive transfusion score.

Abstract: 25–35% of all seriously injured multiple trauma patients are coagulopathic upon arrival to the emergency department, and therefore early diagnosis and intervention on this subset of patients is important. In addition to standard plasma based tests of coagulation, the thromboelastogram (TEG®) has resurfaced as an ideal test in the trauma population to help guide the clinician in the administration of blood components in a goal directed fashion. We describe how thromboelastographic analysis is used to assist in the management of trauma patients with coagulopathies presenting to the emergency department, in surgery, and in the postoperative period. Indications for the utilization of the TEG® and platelet mapping as point of care testing that can guide blood component therapy in a goal directed fashion in the trauma population are presented with emphasis on the more common reasons such as massive transfusion protocol, the management of traumatic brain injury with bleeding, the diagnosis and management of trauma in patients on platelet antagonists, the utilization of recombinant FVIIa, and the management of coagulopathy in terminal trauma patients in preparation for organ donation. The TEG® allows for judicious and protocol assisted utilization of blood components in a setting that has recently gained acceptance. In our program, the inclusion of the perfusionist with expertise in performing and interpreting TEG® analysis allows the multidisciplinary trauma team to more effectively manage blood products and resuscitation in this population.

Emergency operation and intensive care unit admission. Phase 1: From January 1, 1992, to March 31, 1995, we admitted 10255 patients with trauma. Three hundred seven (3%) met the enrollment criteria and were admitted to the operating room (n = 168) or intensive care unit (n = 139). Of these, 58 (18.9%) were taken to the operating room emergently to manage life-threatening injuries: 11 (4%) had craniotomies and 47 (15%) had non-neurosurgical operations. Phase 2: From July 1 to December 31, 1996, 2770 trauma patients were transported to our facility; 135 (4.9%) met the enrollment criteria. Forty-one (30.4%) of these required admission, and 6 (4.4%) were taken emergently to the operating room from the emergency department (1 [1%] for a craniotomy, 3 [2.2%] for intra-abdominal bleeding, and 2 [1.5%] for other procedures). Two (1.5%) of the 135 patients died. Patients with isolated transient loss of consciousness are at significant risk of critical surgical and neurosurgical injuries. These patients should be triaged to trauma centers or hospitals with adequate imaging, surgical, and neurosurgical resources.

This study evaluates the efficacy of arterial embolization (AE) for blunt hepatic traumas (BHT) as part of a combined management strategy based on the hemodynamic status of patients and CT findings. From 2000 to 2005, 84 patients were admitted to our hospital for BHT. Of these, 14 patients who had high-grade injuries (grade III [n = 2], grade IV [n = 9], grade V [n = 3]) underwent AE because of arterial bleeding and were included in the study. They were classified into three groups according to their hemodynamic status: (1) unresponsive shock, (2) shock improved with resuscitation, and (3)more » hemodynamic stability. Four patients (group 1) underwent, first, laparotomy with packing and, then, AE for persistent bleeding. Ten patients who were hemodynamically stable (group 1) or even unstable (group 2) underwent AE first, based on CT findings. AE was successful in all cases. The mortality rate was 7% (1/14). Only two angiography-related complications (gallbladder infarction) were reported. Liver-related complications (abdominal compartment syndrome and biliary complications) were frequent and often required secondary interventions. Our multidisciplinary approach for the management of BHT gives a main role to embolization, even for hemodynamically unstable patients. In this strategy AE is very efficient and has a low complication rate.« less

Incidence of refractory hematuria of prostatic origin (RHPO) is extremely rare, with an iatrogenic etiology even rarer. When conservative methods fail to control bleeding, more invasive surgical methods are needed. In this article we describe our experience with prostatic artery embolization (PAE) as a minimally invasive alternative treatment option in patients with RHPO secondary to iatrogenic urologic trauma. Three patients presented with RHPO. The etiologies were transurethral resection of prostate surgery, Foley catheter removal with a supratherapeutic international normalized ratio and self-traumatic Foley catheter removal respectively. Stepwise management with conservative and medical methods failed to control bleeding. Under local anesthesia and moderate sedation, bilateral PAE was performed via a right common femoral artery access and using cone beam computed tomography. An embolic mixture containing 300-500 um Embosphere® Microspheres (Biosphere Medical, Rockland, MA) was injected under fluoroscopic guidance until stasis was achieved. PAE using the described technique was a technical and clinical success in all three patients. Hematuria resolved within a period of 24 hours. There were no intra- or periprocedural complications. PAE offers a reasonable option in treatment of RHPO, regardless of the cause and may be attempted prior to surgical techniques or sometimes in conjunction. Being minimally invasive and performed under local anesthesia, PAE is especially useful when excessive bleeding prevents adequate visualization of a bleeding source during cystoscopy and in the elderly age group with several comorbidities. An added advantage is the prostatic parenchymal ischemia leading to significant prostate volume reduction and alleviation of the obstructive symptoms. Copyright © 2016 Elsevier Inc.

Renal trauma occurs in approximately 1%-5% of all trauma cases. Improvements in imaging and management over the last two decades have caused a shift in the treatment of this clinical condition. A systematic search of PubMed was performed to identify relevant and contemporary articles that referred to the management and evaluation of renal trauma. Computed tomography remains a mainstay of radiological evaluation in hemodynamically stable patients. There is a growing body of literature showing that conservative, non-operative management of renal trauma is safe, even for Grade IV-V renal injuries. If surgical exploration is planned due to other injuries, a conservative approach to the kidney can often be utilized. Follow up imaging may be warranted in certain circumstances. Urinoma, delayed bleeding, and hypertension are complications that require follow up. Appropriate imaging and conservative approaches are a mainstay of current renal trauma management.

In this study, the factors that effect the morbidity and mortality in patients with penetrating colonic injuries were evaluated. Fourty-two patients (37 males, 5 females; mean age 30,1; range 14 to 63 years) with penetrating colonic trauma were evaluated according to age, gender, type of penetrating trauma, location and severity of the colonic injury, associated injury, interval between the trauma and the definitive operation, hemodynamic status, blood transfusion requirement, fecal contamination, surgical procedure, postoperative complication and mortality. Type of the penetrating trauma was stab injury in twenty-eight (67%) patients, and gunshot injury in fourteen (33%) patients. The mean Colon Injury Severity Score was 2,1. The mean Abdominal Trauma Index (ATI) was 17,2 and it was over than 25 in eight (19%) patients. The symptoms of shock were present in eleven (26%) patients at admission. Blood transfusions were applied in sixteen (38%) patients. In twenty-one patients intraabdominal bleeding was observed and it was more than 500 mL in eleven (26%) patients. Primary repair was performed in 36 (86%) of the 42 patients and colostomy was performed in six (14%) patients. Morbidity and mortality rates were 41% and 10% respectively. It was found that morbidity rates were increased in patients with ATI score higher than 25, and mortality rates were increased in patients presenting shock at admission, with the amount of intraabdominal blood more than 500 mL, and who needed three or more units of blood transfusion. The primary repair of the penetrating colon trauma can be performed confidently in the hemodynamically stable patients with ATI score less than 25.

A 50-year-old man sustained blunt abdominal trauma in a motor vehicle accident. He underwent exploratory laparotomy on the day of trauma, and severe bleeding from the base of the small bowel mesentery was controlled by mass ligation and through-and-through suturing. After transfer to our center, repeat exploratory laparotomy showed ischemic small intestine, ischemic right colon, and severe pancreatic trauma. The severely injured organs were excised including the entire small bowel, pancreas, spleen, stomach, and right hemicolon. The next day, a modified multivisceral transplant was performed including stomach, pancreaticoduodenal complex, and small bowel transplant. Postoperative complications included an intra-abdominal collection that was drained percutaneously with ultrasonographic guidance and severe rejection that was treated with anti-thymocyte globulin. In summary, for select patients who have severe abdominal trauma may be treated with acute multivisceral transplant.

Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

There is scarce evidence about the prognosis of venous thromboembolism in patients undergoing orthopedic surgery and in patients suffering non-surgical trauma. We used the RIETE database (Registro Informatizado de pacientes con Enfermedad Trombo Embólica) to compare the prognosis of venous thromboembolism and the use of thromboprophylaxis in patients undergoing different orthopedic procedures and in trauma patients not requiring surgery. From March 2001 to March 2015, a total of 61,789 patients were enrolled in RIETE database. Of these, 943 (1.52%) developed venous thromboembolism after elective arthroplasty, 445 (0.72%) after hip fracture, 1,045 (1.69%) after non-major orthopedic surgery and 2,136 (3.46%) after non-surgical trauma. Overall, 2,283 patients (50%) initially presented with pulmonary embolism. Within the first 90 days of therapy, 30 patients (0.66%; 95% CI 0.45-0.93) died from pulmonary embolism. The rate of fatal pulmonary embolism was significantly higher after hip fracture surgery (n = 9 [2.02%]) than after elective arthroplasty (n = 5 [0.53%]), non-major orthopedic surgery (n = 5 [0.48%]) or non surgical trauma (n = 11 [0.48%]). Thromboprophylaxis was more commonly used for hip fracture (93%) or elective arthroplasty (94%) than for non-major orthopedic surgery (71%) or non-surgical trauma (32%). Major bleeding was significantly higher after hip fracture surgery (4%) than that observed after elective arthroplasty (1.6%), non-major orthopedic surgery (1.5%) or non-surgical trauma (1.4%). Thromboprophylaxis was less frequently used in lower risk procedures despite the absolute number of fatal pulmonary embolism after non-major orthopedic surgery or non-surgical trauma, exceeded that observed after high risk procedures.

Severe pelvic trauma remains associated with elevated mortality, largely due to hemorrhagic shock. The main study objective was to test for correlation between fracture type and mortality. The secondary objective was to assess the efficacy in terms of mortality of multidisciplinary management following a decision-tree in multiple trauma victims admitted to a level 1 trauma center. Between July 2011 and July 2013, 534 severe trauma patients were included in a single-center continuous prospective observational study. All patients with hemorrhagic shock received early treatment by pelvic binder. Patients with active bleeding on full-body CT or persisting hemorrhagic shock underwent arteriography with or without embolization. Pelvic trauma was graded on the Tile classification. The principle end-point was mortality. Median age was 40 years (range, 26-48 years), with a 79% male/female sex ratio. Thirty-two of the 67 patients with pelvic trauma (48%) were in hemorrhagic shock at admission. Median injury severity score (ISS) was 36 (range, 24-43). On the Tile classification, 22 patients (33%) were grade A, 33 (49%) grade B and 12 (18%) grade C. Overall mortality was 19%, and 42% in case of hemorrhagic shock. Mortality was significantly higher with Tile C than A or B (58% vs. 9.1% and 12.1%, respectively; P=0.001). Vertical shear fracture (Tile C) was associated with greater mortality from hemorrhagic shock. IV, case series. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Blunt chest trauma can cause a wide variety of injuries including acute myocardial infarction (AMI). Although AMI due to coronary artery dissection caused by blunt chest trauma is very rare, it is associated with high morbidity and mortality. In the vast majority of patients with AMI, primary percutaneous coronary interventions (PCI) are performed to recanalize obstructed arteries, but PCI carries a substantial risk of hemorrhagic complications in the acute phase of trauma. We report a case of AMI due to right coronary artery (RCA) dissection caused by blunt chest trauma. The totally obstructed RCA was spontaneously recanalized with medical therapy. We could avoid primary PCI in the acute phase of blunt chest trauma because electrocardiogram showed early reperfusion signs. We performed an elective PCI in the subacute phase when the risk of bleeding subsided. Since the risk of severe hemorrhagic complications is greater in the acute phase of blunt chest trauma as compared with the late phase, deferring emergency PCI is reasonable if signs of recanalization are observed.

Background Over the last decade the age of trauma patients and injury mortality has increased. At the same time, many centers have implemented multiple interventions focused on improved hemorrhage control, effectively resulting in a bleeding control bundle of care. The objective of our study was to analyze the temporal distribution of trauma-related deaths, the factors that characterize that distribution and how those factors have changed over time at our urban level 1 trauma center. Methods Records at a urban Level 1 trauma center were reviewed. Two time periods (2005–2006 and 2012–2013) were included in the analysis. Mortality rates were directly adjusted for age, gender and mechanism of injury. The Mann-Whitney and chi square tests were used to compare variables between periods, with significance set at 0.05. Results 7080 patients (498 deaths) were examined in 2005–2006, while 8767 patients (531 deaths) were reviewed in 2012–2013. The median age increased 6 years, with a similar increase in those who died. In patients that died, no differences by gender, race or ethnicity were observed. Fall-related deaths are now the leading cause of death. Traumatic brain injury (TBI) and hemorrhage accounted for > 91% of all deaths. TBI (61%) and multiple organ failure or sepsis (6.2%) deaths were unchanged, while deaths associated with hemorrhage decreased from 36% to 25% (p<0.01). Across time periods, 26% of all deaths occurred within one hour of hospital arrival, while 59% occurred within 24 hours. Unadjusted mortality dropped from 7.0% to 6.1% (p=0.01) and in-hospital mortality dropped from 6.0% to 5.0% (p<0.01). Adjusted mortality dropped 24% from 7.6% (95% CI: 6.9–8.2) to 5.8% (95% CI: 5.3–6.3) and in-hospital mortality decreased 30% from 6.6% (95% CI: 6.0–7.2) to 4.7 (95% CI: 4.2–5.1). Conclusions Over the same time frame of this study, increases in trauma death across the globe have been reported. This single-site study demonstrated a significant reduction in mortality, likely attributable to decreased hemorrhagic death. It is possible that efforts focused on hemorrhage control interventions (a bleeding control bundle) resulted in this reduction. These changing factors provide guidance on future prevention and intervention efforts. PMID:27847192

The resuscitative endovascular balloon occlusion of the aorta, because of its efficacy and feasibility, has been widely used in treating patients with severe torso trauma. However, complications developing around the site proximal to the occlusion by resuscitative endovascular balloon occlusion of the aorta have almost never been studied. A 50-year-old Japanese woman fell from a height of approximately 10 m. At initial arrival, her respiratory rate was 24 breaths/minute, her blood oxygen saturation was 95% under 10 L/minute oxygenation, her pulse rate was 90 beats per minute, and her blood pressure was 180/120 mmHg. Mild lung contusion, hemopneumothorax, unstable pelvic fracture, and retroperitoneal bleeding with extravasation of contrast media were observed in initial computed tomography. As her vital signs had deteriorated during computed tomography, a 7-French aortic occlusion catheter (RESCUE BALLOON®, Tokai Medical Products, Aichi, Japan) was inserted and inflated for aortic occlusion at the first lumbar vertebra level and transcatheter arterial embolization was performed for the pelvic fracture. Her bilateral internal iliac arteries were embolized with a gelatin sponge; however, the embolized sites presented recanalization as coagulopathy appeared. Her bilateral internal iliac arteries were re-embolized by n-butyl-2-cyanoacrylate. The balloon was deflated 18 minutes later. After embolization, repeat computed tomography was performed and a massive hemothorax, which had not been captured on arrival, had appeared in her left pleural cavity. Thoracotomy hemostasis was performed and a hemothorax of approximately 2500 ml was aspirated to search for the source of bleeding. However, clear active bleeding was not captured; resuscitative endovascular balloon occlusion of the aorta may have been the cause of the increased bleeding of the thoracic injury at the proximal site of the aorta occlusion. It is necessary to note that the use of resuscitative endovascular balloon occlusion of the aorta may increase bleeding in sites proximal to occlusions, even in the case of minor injuries without active bleeding at the initial diagnosis.

Hypothermia is present in up to two-thirds of patients with severe injury, although it is often disregarded during the initial resuscitation. Studies have revealed that hypothermia is associated with mortality in a large percentage of trauma cases when the patient's temperature is below 32 °C. Risk factors include the severity of injury, wet clothing, low transport unit temperature, use of anesthesia, and prolonged surgery. Fortunately, associated coagulation disorders have been shown to completely resolve with aggressive warming. Selected passive and active warming techniques can be applied in damage control resuscitation. While treatment guidelines exist for acidosis and bleeding, there is no evidence-based approach to managing hypothermia in trauma patients. We synthesized a goal-directed algorithm for warming the severely injured patient that can be directly incorporated into current Advanced Trauma Life Support guidelines. This involves the early use of warming blankets and removal of wet clothing in the prehospital phase followed by aggressive rewarming on arrival at the hospital if the patient's injuries require damage control therapy. Future research in hypothermia management should concentrate on applying this treatment algorithm and should evaluate its influence on patient outcomes. This treatment strategy may help to reduce blood loss and improve morbidity and mortality in this population of patients.

Improved mortality from penetrating neck and maxillofacial trauma using Foley catheter balloon tamponade in combat.

The military medical community has promoted use of Foley catheter balloon tamponade in the initial management of vascular injury owing to neck or maxillofacial trauma. The aim of the study was to compare outcomes with Foley catheter tamponade with those obtained with traditional use of external pressure. This retrospective cohort study evaluated all cases of persistent bleeding caused by penetrating neck or maxillofacial trauma received at one forward aid station between December 2009 and October 2011. Cohorts included those who were treated with Foley catheter tamponade and those managed with external pressure. Which treatment option was applied depended solely on the availability of Foley catheters at the time. The effectiveness of each technique in controlling initial and delayed hemorrhage is described, and the impact on mortality is analyzed using the Student's t test and Fisher's exact test. Seventy-seven subjects met the inclusion criteria with 42 subjects in the Foley group and 35 subjects in the external pressure group. A statistically significant difference was found between the groups regarding delayed failure, experienced by three patients (7%) in the Foley group and nine patients (26%) in the external pressure group (p < 0.05). The difference in mortality, 5% (two patients) in the Foley tamponade group and 23% (eight patients) in the external pressure group, was statistically significant (p < 0.05). For penetrating neck and maxillofacial injuries in a combat environment, Foley catheter balloon tamponade significantly reduced mortality when compared with direct pressure techniques through its effect on preventing delayed bleeding.

Despite the higher theoretical risk of traumatic intracranial hemorrhage (ICH) in anticoagulated patients with mild head injury, the value of sequential head CT scans to identify bleeding remains controversial. This study evaluated the utility of 2 sequential CT scans at a 48-hour interval (CT1 and CT2) in patients with mild head trauma (Glasgow Coma Scale 13-15) taking oral anticoagulants. We retrospectively evaluated the clinical records of all patients on chronic anticoagulation treatment admitted to the emergency department for mild head injury. A total of 344 patients were included, and 337 (97.9%) had a negative CT1. CT2 was performed on 284 of the 337 patients with a negative CT1 and was positive in 4 patients (1.4%), but none of the patients developed concomitant neurologic worsening or required neurosurgery. Systematic routine use of a second CT scan in mild head trauma in patients taking anticoagulants is expensive and clinically unnecessary.

The authors analyse clinical cases of penetrating thoracic, abdominal, perineal and anorectal injury and describe the traumatic event and type of lesion, the principles of surgical treatment, the complication rate and follow up. In the last 24 months, we analyzed 10 consecutive cases of penetrating thoracic and abdominal wounds [stab wound (n=7), with evisceration (n=4), gunshot wound (n=1)], and penetrating perineal and anorectal wounds (impalement n=4). In addition, we report an unusual case of neck injury from a stab wound. All the patients underwent emergency surgery for the lesions reported. In 7 cases of perforating vulnerant thoracoabdominal trauma from stab wounds there was hemoperitoneum due to bleeding from the abdominal wall (n=3), the omentum (n=1), the vena cava (n=1) and the liver (n=2). Evisceration of the omentum was observed in 4 cases. In 2 cases laparoscopy was performed. In one case laparotomy and thoracoscopy was performed. In a patient with an abdominoperineal gunshot wound, exploration was extraperitoneal. The 4 cases of perineal and anorectal impalement were treated with primary reconstruction, while in one case a laparotomy was needed to suture the rectum and fashion a temporary colostomy. In one case of anorectal injury rehabilitation resulted in a gradual improvement of fecal continence, while in the patient with the colostomy follow up at 2 months was scheduled to plan colostomy closure. Based on the our clinical experience and the literature, in penetrating abdominal trauma laparotomy may be required if patients are hemodynamically unstable (or in hemorrhagic shock), in patients with evisceration and peritonitis, or for exploration of penetrating thoracoabdominal and epigastric lesions. In anterior injuries of the abdominal wall from gunshot or stab wounds, laparotomy is indicated when there is peritoneal violation and significant intraperitoneal damage. In patients with actively bleeding wounds of the abdominal wall muscles minimal laparotomy is often necessary for control of hemorrhage and abdominal wall reconstruction to avoid herniation. If patients are asymptomatic, in cases of anterior lesions the indications for diagnostic laparoscopy are uncertain. Selective conservative treatment is reserved for asymptomatic patients who are hemodynamically stable. Further controlled studies are needed. Early surgery for perineal and anorectal trauma, and also for complex injuries, is the gold standard for treatment.

To evaluate the use of routinely collected data to determine the cause(s) of critical bleeding in patients who receive massive transfusion (MT). Routinely collected data are increasingly being used to describe and evaluate transfusion practice. Chart reviews were undertaken on 10 randomly selected MT patients at 48 hospitals across Australia and New Zealand to determine the cause(s) of critical bleeding. Diagnosis-related group (DRG) and International Classification of Diseases (ICD) codes were extracted separately and used to assign each patient a cause of critical bleeding. These were compared against chart review using percentage agreement and kappa statistics. A total of 427 MT patients were included with complete ICD and DRG data for 427 (100%) and 396 (93%), respectively. Good overall agreement was found between chart review and ICD codes (78·3%; κ = 0·74, 95% CI 0·70-0·79) and only fair overall agreement with DRG (51%; κ = 0·45, 95% CI 0·40-0·50). Both ICD and DRG were sensitive and accurate for classifying obstetric haemorrhage patients (98% sensitivity and κ > 0·94). However, compared with the ICD algorithm, DRGs were less sensitive and accurate in classifying bleeding as a result of gastrointestinal haemorrhage (74% vs 8%; κ = 0·75 vs 0·1), trauma (92% vs 62%; κ = 0·78 vs 0·67), cardiac (80% vs 57%; κ = 0·79 vs 0·60) and vascular surgery (64% vs 56%; κ = 0·69 vs 0·65). Algorithms using ICD codes can determine the cause of critical bleeding in patients requiring MT with good to excellent agreement with clinical history. DRG are less suitable to determine critical bleeding causes. © 2016 British Blood Transfusion Society.

Massive transfusion (MT) is a lifesaving treatment for trauma patients with hemorrhagic shock, assessed by Assessment of Blood Consumption (ABC) Score based on mechanism of injury, systolic blood pressure (SBP), tachycardia, and FAST exam. The aim of this study was to assess the performance of ABC score by replacing hypotension and tachycardia; with Shock Index (SI) > 1.0 and including pelvic fractures. We performed a 2-year (2014-2015) analysis of all high-level trauma activations and excluded patients dead on arrival. The ABC score was calculated using the 4-point score [blunt (0)/penetrating trauma (1), HR ≥ 120 (1), SBP ≤ 90 mmHg (1), and FAST positive (1)]. The Revised Assessment of Bleeding and Transfusion (RABT) score also included 4 points, calculated by replacing HR and SBP with SI > 1.0 and including pelvic fracture. AUROC compared performances of the two scores. A total of 380 patients were included. The overall MT was 27%. Patients receiving MT had higher median ABC scores [1.1 (0-2) vs. 1 (0-2), p = 0.15] and RABT scores [2 (1-3) vs. 1 (0-2), p < 0.001]. The RABT score had better discriminative power (AUROC = 0.828) compared to ABC score (AUROC = 0.617) for predicting the need for MT. Cutoff of RABT score ≥ 2 had a sensitivity of 84% and specificity of 77% for predicting need for MT compared to ABC score with 39% sensitivity and 72% specificity. Replacement of hypotension and tachycardia with a SI > 1.0 and inclusion of pelvic fracture enhanced discrimination of ABC score for predicting the need for MT. The current ABC score would benefit from revision to more appropriately identify patients requiring MT.

Recently, three patients with hemopericardium after severe chest trauma were successfully managed nonoperatively at our institution. This prompted the question whether these were rare or common events. Therefore, we reviewed our experience with similar injuries to test the hypothesis that trauma-induced hemopericardium mandates sternotomy. Records were retrospectively reviewed for all patients at a Level I trauma center (December 1996 to November 2011) who sustained chest trauma with pericardial window (PCW, n = 377) and/or median sternotomy (n = 110). Fifty-five (15%) patients with positive PCW proceeded to sternotomy. Penetrating injury was the dominant mechanism (n = 49, 89%). Nineteen (35%) were hypotensive on arrival or during initial resuscitation. Most received surgeon-performed focused cardiac ultrasound examinations (n = 43, 78%) with positive results (n = 25, 58%). Ventricular injuries were most common, with equivalent numbers occurring on the right (n = 16, 29%) and left (n = 15, 27%). Six (11%) with positive PCW had isolated pericardial lacerations, but 21 (38%) had no repairable cardiac or great vessel injury. Those with therapeutic versus nontherapeutic sternotomies were similar with respect to age, mechanisms of injury, injury severity scores, presenting laboratory values, resuscitation fluids, and vital signs. Multiple logistic regression revealed that penetrating trauma (odds ratio: 13.3) and hemodynamic instability (odds ratio: 7.8) were independent predictors of therapeutic sternotomy. Hemopericardium per se may be overly sensitive for diagnosing cardiac or great vessel injuries after chest trauma. Some stable blunt or penetrating trauma patients without continuing intrapericardial bleeding had nontherapeutic sternotomies, suggesting that this intervention could be avoided in selected cases.

Bystander first aid and basic life support can likely improve victim survival in trauma. In contrast to bystander first aid and out-of-hospital cardiac arrest, little is known about the role of bystanders in trauma response. Our aim was to determine how frequently first aid is given to trauma victims by bystanders, the quality of this aid, the professional background of first-aid providers, and whether previous first-aid training affects aid quality. We conducted a prospective 18-month study in two mixed urban-rural Norwegian counties. The personnel on the first ambulance responding to trauma calls assessed and documented first aid performed by bystanders using a standard form. A total of 330 trauma calls were included, with bystanders present in 97% of cases. Securing an open airway was correctly performed for 76% of the 43 patients in need of this first-aid measure. Bleeding control was provided correctly for 81% of 63 patients for whom this measure was indicated, and prevention of hypothermia for 62% of 204 patients. Among the first-aid providers studied, 35% had some training in first aid. Bystanders with documented first-aid training gave better first aid than those where first-aid training status was unknown. A majority of the trauma patients studied received correct pre-hospital first aid, but still there is need for considerable improvement, particularly hypothermia prevention. Previous first-aid training seems to improve the quality of first aid provided. The effect on patient survival needs to be investigated. © 2015 The Authors.

Unlike hepatic haemorrhage following blunt abdominal trauma, spontaneous abdomen bleeding is rare, even in the presence of a hepatocellular adenoma (HA) or carcinoma. However, the diagnosis of a tumour underlying a haematoma after liver trauma is unusual, especially when it occurs more after two years after the accident. Here, we report a case of a ruptured HA due to blunt abdominal trauma. A 36-year-old woman was admitted to our hospital with sudden onset of upper abdominal pain. Her medical history revealed a blunt abdominal trauma two years prior. Initial abdominal computed tomography scan revealed a large haematoma measuring more than 16 cm in diameter in the right lobe of the liver. Magnetic resonance imaging showed haemorrhagic areas and some regions with hepatocyte hyperplasia, suggesting HA. The patient underwent right hepatic lobectomy, and a histopathological examination confirmed a diagnosis of HA. In conclusion, it is important to consider that abdominal trauma may hide old, asymptomatic and not previously detected injuries, as in the case reported.

The role of interventional radiology in abdominopelvic trauma

The management of trauma patients has evolved in recent decades owing to increasing availability of advanced imaging modalities such as CT. Nowadays, CT has replaced the diagnostic function of angiography. The latter is considered when a therapeutic option is hypothesized. Arterial embolization is a life-saving procedure in abdominopelvic haemorrhagic patients, reducing relevant mortality rates and ensuring haemodynamic stabilization of the patient. Percutaneous transarterial embolization has been shown to be effective for controlling ongoing bleeding for patients with high-grade abdominopelvic injuries, thereby reducing the failure rate of non-operative management, preserving maximal organ function. Surgery is not always the optimal solution for stabilization of a patient with polytrauma. Mini-invasivity and repeatability may be considered as relevant advantages. We review technical considerations, efficacy and complication rates of hepatic, splenic, renal and pelvic embolization to extrapolate current evidence about transarterial embolization in traumatic patients.

Presently, trauma guidelines recommend epidural analgesia as the optimal modality of pain relief from rib fractures. They are not ideally suited for elderly trauma patients and have disadvantages including bleeding risk. The paravertebral analgesic pump (PVP) eliminates such disadvantages and includes ease of placement in the trauma setting. This study compares pain control in patients treated by EPI versus PVP. This is a retrospective, historical cohort study comparing two methods of pain management in the trauma setting. Before 2010, patients who had epidural catheters (EPI) placed for pain control were compared with patients after 2010 in which the PVP was used. All patients had multiple rib fractures as diagnosed by CT scan. Analysis was adjusted for age, number of fractures, and comorbid conditions. Multiple linear regression analysis was conducted to compare average reported pain. A total of 110 patients, 31 PVP and 79 epidural catheters, were included in the study. Overall mean age was 65 years. The mean Injury Severity Score was 12.0 (EPI) and 11.1 (PVP). Mean number rib fractures was 4.29 (EPI) and 4.71 (PVP). PVP was associated with a 30 per cent greater decrease in pain than that seen with EPI (6.0-1.9 vs 6.4-3.4). After controlling for age, Injury Severity Score, and number of rib fractures, there were no differences in intensive care unit or total length of stay (P = 0.35) or in pain score (3.76 vs 3.56, P = 0.64). In conclusion, the PVP compares well with epidural analgesia in older trauma patients yet is safe, well tolerated, and easily inserted.

Our objective was to review the technical success and clinical outcomes of transcatheter embolization of peripheral renal artery with FuAiLe medical glue (FAL). All patients who underwent FAL embolization for peripheral renal artery bleeding were retrospectively analyzed for underlying pathologies, technical success and outcome of embolization procedure. 14 consecutive patients underwent FAL embolization between November 2009 and February 2013. The causes of bleeding were post biopsy (n = 5), blunt trauma (n = 5), percutaneous lithotripsy of kidney stones (n = 3), and complication of cardiac catheterization (n = 1). Bleeding was effectively controlled with a single injection of FAL. Mean volume of FAL mixture (FAL:Lipiodol, 1:1) was 0.5 mL (range, 0.2–0.8 mL). No reflux of the embolic agent was noted. Average cost of FAL for each procedure was $74. Postembolization clinical follow-up showed no evidence of recurrent hematuria, progression of hematoma, hypertension, or elevation of serum creatinine. Doppler ultrasound examinations in 13 patients demonstrated no abscess, renal parenchyma infarction, or renal artery abnormalities. Superselective FAL embolization may be used for the treatment of active bleeding from peripheral renal arteries. It has a high success rate and is quicker and less expensive than embolization with other agents. PMID:25765607

Pseudoaneurysm of the Profunda Femoris Artery following Blunt Trauma Treated by Endovascular Coil Embolization: Review of Two Cases and Relevant Literature

PubMed Central

2017-01-01

Profunda femoris artery (PFA) pseudoaneurysm after blunt trauma without associated femur fracture is a rare occurrence. Most of the reported cases of PFA pseudoaneurysm in the English literature developed after penetrating trauma, surgical procedures, and femur fractures. We present two such cases following blunt trauma and without any associated long bone injury. After initial imaging failed to show any long bone fracture, CT angiography confirmed pseudoaneurysm of the branch of the PFA. Both patients were then treated with emergent coil embolization of the bleeding vessel. Pseudoaneurysms typically present late and signs of persistent hip pain, thigh swelling, presence of a pulsatile mass, and even unexplained anemia all may suggest the diagnosis. Recognition of PFA pseudoaneurysm requires high index of suspicion and is often difficult to diagnose clinically because of its location. PMID:28246563

Intracranial hemorrhage (ICH) is a medical emergency. In congenital bleeding disorders, ICH is a devastating presentation accompanied with a high rate of morbidity and mortality. The prevalence of ICH is highly variable among congenital bleeding disorders, with the highest incidence observed in factor (F) XIII deficiency (FXIIID) (∼30%). This life-threatening presentation is less common in afibrinogenemia, FVIII, FIX, FVII, and FX deficiencies, and is rare in severe FV and FII deficiencies, type 3 von Willebrand disease and inherited platelet function disorders (IPFDs). In FXIIID, this diathesis most often occurs after trauma in children, whereas spontaneous ICH is more frequent in adults. About 15% of patients with FXIIID and ICH die; the bleeding causes 80% of deaths in this coagulopathy. Although in FXIIID, the bleed most commonly is intraparenchymal (> 90%), epidural, subdural, and subarachnoid hemorrhages also have been reported, albeit rarely. As this life-threatening bleeding causes neurological complications, early diagnosis can prevent further expansion of the hematoma and secondary damage. Neuroimaging plays a crucial role in the diagnosis of ICH, but signs and symptoms in patients with severe FXIIID should trigger replacement therapy even before establishment of the diagnosis. Although a high dose of FXIII concentrate can reduce the rate of morbidity and mortality of ICH in FXIIID, it may occasionally trigger inhibitor development, thus complicating ICH management and future prophylaxis. Nevertheless, replacement therapy is the mainstay of treatment for ICH in FXIIID. Neurosurgery is performed in patients with FXIIID and epidural hematoma and a hemorrhage diameter exceeding 2 cm or a volume of ICH is more than 30 cm 3 . Contact sports are not recommended in people with FXIIID as they can elicit ICH. However, a considerable number of safe sports and activities have been suggested to have more benefits than dangers for patients with congenital bleeding disorders, and are hence suitable for these patients.

Pharmacological prophylaxis for venous thromboembolism (VTE) in the neurosurgical population is still a matter of debate, as the risk-to-benefit ratio is not well defined. To further evaluate the risk-to-benefit ratio of VTE prophylaxis (VTEP) for all neurosurgical procedures. A prospective evaluation was performed after the initiation of a VTEP protocol for 11 436 patients undergoing neurosurgical procedures over 24 mo. Unless a bleeding complication was present, 5000 international units of subcutaneous heparin every 8 h was ordered on postoperative day (POD) 1 for spine, POD2 for cranial, and by POD4 for subdural, intracerebral, and epidural hematoma cases. Incidence of VTE and any subsequent bleeding complications were noted. A total of 70 VTEs (0.6% overall) were documented (28 deep vein thrombosis, 42 pulmonary embnolism). The highest rates of VTE were associated with deformity (6.7%); open cerebrovascular (6.5%); subdural, intracerebral, and epidural hematoma (3.2%); spinal trauma (2.4%); and craniotomy for tumor (1.6%) cases. Seven cases of deep vein thrombosis progressed to pulmonary embolisms, and 66 of 70 VTEs occurred while on pharmacological VTEP. Fifty-four bleeding complications occurred on or after POD2 following initiation of VTEP. These bleeding complications consisted of any new clinically or radiographically observed hemorrhages. Twenty-eight of the 54 delayed bleeding complications required operative intervention with 1 mortality. Forty-five patients were on anticoagulation when the initial bleeding event occurred. Overall, an estimated 0.5% incidence of delayed bleeding complications was noted with 99.4% of patients within the study cohort remaining VTE free. This VTEP protocol was determined to afford a good risk-to-benefit ratio for a wide variety of neurosurgical procedures.

Military and civilian data would suggest that hemostatic resuscitation results in improved outcomes for exsanguinating patients. However, identification of those patients who are at risk of significant hemorrhage is not clearly defined. We attempted to identify factors that would predict the need for massive transfusion (MT) in an Australasian trauma population, by comparing those trauma patients who did receive massive transfusion with those who did not. Between 1985 and 2010, 1,686 trauma patients receiving at least 1 U of packed red blood cells were identified from our prospectively maintained trauma registry. Demographic, physiologic, laboratory, injury, and outcome variables were reviewed. Univariate analysis determined significant factors between those who received MT and those who did not. A predictive multivariate logistic regression model with backward conditional stepwise elimination was used for MT risk. Statistical analysis was performed using SPSS PASW. MT patients had a higher pulse rate, lower Glasgow Coma Scale (GCS) score, lower systolic blood pressure, lower hemoglobin level, higher Injury Severity Score (ISS), higher international normalized ratio (INR), and longer stay. Initial logistic regression identified base deficit (BD), INR, and hemoperitoneum at laparotomy as independent predictive variables. After assigning cutoff points of BD being greater than 5 and an INR of 1.5 or greater, a further model was created. A BD greater than 5 and either INR of 1.5 or greater or hemoperitoneum was associated with 51 times increase in MT risk (odds ratio, 51.6; 95% confidence interval, 24.9-95.8). The area under the receiver operating characteristic curve for the model was 0.859. From this study, a combination of BD, INR, and hemoperitoneum has demonstrated good predictability for MT. This tool may assist in the determination of those patients who might benefit from hemostatic resuscitation. Prognostic study, level III.

Following blunt splenic injury, there is conflicting evidence regarding the natural history and appropriate management of patients with vascular injuries of the spleen such as pseudoaneurysms or blushes. The purpose of this study was to describe the current management and outcomes of patients with pseudoaneurysm or blush. Data were collected on adult (aged ≥18 years) patients with blunt splenic injury and a splenic vascular injury from 17 trauma centers. Demographic, physiologic, radiographic, and injury characteristics were gathered. Management and outcomes were collected. Univariate and multivariable analyses were used to determine factors associated with splenectomy. Two hundred patients with a vascular abnormality on computed tomography scan were enrolled. Of those, 14.5% were managed with early splenectomy. Of the remaining patients, 59% underwent angiography and embolization (ANGIO), and 26.5% were observed. Of those who underwent ANGIO, 5.9% had a repeat ANGIO, and 6.8% had splenectomy. Of those observed, 9.4% had a delayed ANGIO, and 7.6% underwent splenectomy. There were no statistically significant differences between those observed and those who underwent ANGIO. There were 111 computed tomography scans with splenic vascular injuries available for review by an expert trauma radiologist. The concordance between the original classification of the type of vascular abnormality and the expert radiologist's interpretation was 56.3%. Based on expert review, the presence of an actively bleeding vascular injury was associated with a 40.9% risk of splenectomy. This was significantly higher than those with a nonbleeding vascular injury. In this series, the vast majority of patients are managed with ANGIO and usually embolization, whereas splenectomy remains a rare event. However, patients with a bleeding vascular injury of the spleen are at high risk of nonoperative failure, no matter the strategy used for management. This group may warrant closer observation or an alternative management strategy. Prognostic study, level III.

Acute gastrointestinal bleeding (GIB) can lead to significant morbidity and mortality without appropriate treatment. There are numerous causes of acute GIB including but not limited to infection, vascular anomalies, inflammatory diseases, trauma, and malignancy. The diagnostic and therapeutic approach of GIB depends on its location, severity, and etiology. The role of interventional radiology becomes vital in patients whose GIB remains resistant to medical and endoscopic treatment. Radiology offers diagnostic imaging studies and endovascular therapeutic interventions that can be performed promptly and effectively with successful outcomes. Computed tomography angiography and nuclear scintigraphy can localize the source of bleeding and provide essential information for the interventional radiologist to guide therapeutic management with endovascular angiography and transcatheter embolization. This review article provides insight into the essential role of Interventional Radiology in the management of acute GIB. PMID:24778770

Intrahepatic portal vein injuries secondary to blunt abdominal trauma are difficult to diagnose and can result in insidious bleeding. We aimed to compare computed tomography arterial portography (CTAP), reperfusion CTAP (rCTAP), and conventional computed tomography (CT) for diagnosing portal vein injuries after blunt hepatic trauma. Patients with blunt hepatic trauma, who were eligible for nonoperative management, underwent CTAP, rCTAP, and CT. The number and size of perfusion defects observed using the three methods were compared. A total of 13 patients (seven males/six females) with a mean age of 34.5±14.1 years were included in the study. A total of 36 hepatic segments had perfusion defects on rCTAP and CT, while there were 47 hepatic segments with perfusion defects on CTAP. The size of perfusion defects on CT (239 cm3; interquartile range [IQR]: 129.5, 309.5) and rCTAP (238 cm3; IQR: 129.5, 310.5) were significantly smaller compared with CTAP (291 cm3; IQR: 136, 371) (both, P = 0.002). Perfusion defects measured by CTAP were significantly greater than those determined by either rCTAP or CT in cases of blunt hepatic trauma. This finding suggests that CTAP is superior to rCTAP and CT in evaluating portal vein injuries after blunt liver trauma.

Video-assisted thoracoscopic surgery for retained hemothorax in blunt chest trauma

Purpose of review In the last decade, video-assisted thoracoscopic surgery (VATS) has become a popular method in diagnosis and treatment of acute chest injuries. Except for patients with unstable vital signs who require larger surgical incisions to check bleeding, this endoscopic surgery could be employed in the majority of thoracic injury patients with stable vital signs. Recent findings In the past, VATS was used to evacuate traumatic-retained hemothorax. Recent study has revealed further that lung repair during VATS could decrease complications after trauma. Management of fractured ribs could also be assisted by VATS. Early VATS intervention within 7 days after injury can decrease the rate of posttraumatic infection and length of hospital stay. In studies of the pathophysiology of animal models, N-acetylcysteine and methylene blue were used in animals with blunt chest trauma and found to improve clinical outcomes. Summary Retained hemothorax derived from blunt chest trauma should be managed carefully and rapidly. Early VATS intervention is a well tolerated and reliable procedure that can be applied to manage this complication cost effectively. PMID:25978625

Dislodgement of variceal bands after esophageal balloon tamponade for variceal bleeding.

2014-01-01

A 43-year-old male with alcoholic cirrhosis underwent EGD for hematemesis which revealed bleeding, grade II, lower esophageal varices that were endoscopically ligated with 6 bands. All the bands remained attached to varices at the completion of EGD. Despite apparent initial hemostasis, balloon tamponade was performed one hour later for suspected continued bleeding. Due to suspected continuing bleeding, EGD was repeated 4 h after initial EGD, and 3 h after balloon tamponade. This EGD revealed the esophageal varices; none of the bands remaining on esophageal mucosa; multiple mucosal stigmata likely from trauma at initial site of variceal bands before dislodgement; and 3 dislodged bands in gastric body, duodenal bulb, or descending duodenum. The patient expired 17 h thereafter from hypovolemic shock. This single report may suggest an apparently novel, balloon tamponade complication: dislodgement of previously placed, endoscopic bands. The proposed pathophysiology is release of bands by stretching entrapped, esophageal mucosa during esophageal balloon tamponade. This complication, if confirmed, might render balloon tamponade a less desirable option very soon after band ligation.

The aim of this study is to evaluate the difference in perioperative complication rate in total hip, bipolar hemiarthroplasties and total knee arthroplasty in patients with Parkinson disease in trauma and elective surgery in our Musculoskeletal Center during a period of 10 years. Between 2006 and 2016, 45 bipolar hemiarthroplasties in trauma surgery, 15 total knee and 19 total hip arthroplasties in patients with Parkinson's disease were performed. We divided the patients in two groups. Group I included trauma cases (45) and group II elective surgery cases (34). Complications were documented and divided into local minor and major complications and general minor and major complications. Fisher's exact test was used for statistical evaluation. In both groups, there was one local major complication (p > 0.05): In group I, there was one case of loosening of a K-wire which was removed operatively. In group II, there was one severe intraarticular bleeding requiring puncture of the hematoma. In group I, there were 38 general complications; in group II, there were 17 general complications. There was no statistical difference in complication rate (p > 0.05). Total hip arthroplasty, bipolar hemiarthroplasties and knee arthroplasty in patients with Parkinson disease is possible in elective and trauma surgery. Complication rate is higher in comparison with patients not suffering from Parkinson disease, but there is no difference in complication rate in elective and trauma surgery. Nevertheless, early perioperative neurological consultation in patients with Parkinson disease is recommended to minimize complications and improve early outcomes after arthroplasty.

Koto, M Z; Mosai, F; Matsevych, O Y

2017-06-01

The use of laparoscopy in blunt abdominal trauma is gaining popularity as a useful diagnostic tool to avoid unnecessary laparotomies where there is diagnostic dilemma. But the feasibility of using laparoscopy for therapeutic intervention in these patients has been debated. Even though recent case reports seem to suggest that these patients can be managed using laparoscopy, the practice is not yet wildly adopted. A retrospective analysis of a prospectively collected data was done. All adult patients who presented with abdominal trauma and were offered laparoscopic surgery at Dr George Mukhari Academic Hospital (DGMAH) from 2012 to 2015 were reviewed. Data was retrieved from our departmental database and analysed using descriptive statistics. A total of 318 patients were reviewed and 35 patients had blunt abdominal trauma and were included in the study. All the patients were offered laparoscopy. The median age was 30, with 91% of our patients males. The highest injury severity score calculated was 38. At least 77% of the patients were managed using laparoscopy. This includes 43% who had both diagnostic and therapeutic intervention and 34% who had only diagnostic laparoscopy. Eight patients were converted to open surgery mainly due to active bleeding and complex injuries. We did not have any non-therapeutic laparotomies. There was no documented procedure‑related morbidity and mortality. The positive outcomes seen from the study suggest that laparoscopy can be safe and feasible in both diagnostic and therapeutic interventions in carefully selected blunt abdominal trauma patients. A conversion to open surgery should not be regarded as a failure but rather as a sign of mature and sound clinical judgement acknowledging the limitations of laparoscopy and/or the surgeon.

An increasing proportion of trauma patients are on anticoagulation or antiplatelet therapy. Unlike warfarin, where measuring international normalized ratio can help direct management, measuring platelet inhibition from clopidogrel (Plavix) is not standardized. We report the use of a new P2Y12 point-of-care assay (VerifyNow; Accumetrics, San Diego, CA) to determine the magnitude of platelet inhibition in trauma patients using clopidogrel. Trauma patients in 2009 were queried for clopidogrel use by prehospital personnel and the trauma team. Blood was obtained on admission for patients reportedly taking clopidogrel and was assayed for platelet inhibition using the VerfiyNow-P2Y12 device that measures P2Y12 reaction units and photometrically determines platelet inhibition percentage within 30 minutes. Patient demographics including age, Injury Severity Score, mechanism of injury, and complications from hemorrhage were also analyzed. In the time studied, 46 patients taking clopidogrel were assayed for platelet inhibition. The mean age was 75.9 years±11.8 years, and the most common mechanism of injury was fall (86.9%). Platelet inhibition ranged from 0% to 89%. There were no deaths, and only two patients, from the 0% and>30% inhibition group, had hemorrhagic complications (increased intracranial hemorrhage). The P2Y12 point-of-care assay determined that a large percentage of patients had undetectable or low platelet inhibition despite reportedly being on clopidogrel therapy. These patients may be clopidogrel nonresponders or noncompliant. It is unlikely that clopidogrel reversal therapies, such as platelet transfusions or Desmopressin, would be beneficial in this group. Further studies stratifying the percent platelet inhibition needed to increase bleeding complications is warranted to optimize management strategies.

Background Blunt diaphragmatic rupture (BDR) is a rare event and represents a diagnostic challenge. The purpose of our study was to review our experience with BDR at the Sunnybrook Health Sciences Centre (Sunnybrook), the largest trauma centre in Canada, and to highlight recent changes in the diagnosis and management of the condition. Methods We retrospectively reviewed the cases of patients with BDR who were admitted to Sunnybrook between January 1986 and December 2003 using our trauma registry. We performed Student t and Fisher exact tests to compare our findings on patients with BDR with those on the entire cohort of blunt trauma patients admitted to our centre. Results Most patients with BDR were men (64.4%) with a mean age of 42 years. Left-sided tears were most common (65.0%). Patients with BDR had a very high Injury Severity Score (38) and very high mortality (28.8%). Of those who were injured as a result of motor vehicle collisions (MVCs), a significantly greater percentage of patients in the BDR group than in the entire cohort of blunt trauma patients were drivers or front-seat passengers. Patients with BDR were also significantly less likely to be pedestrians, to have experienced a fall or to be involved in a motorcycle collision. Patients with BDR had a higher chest, abdomen, pelvis and extremity Abbreviated Injury Scale score than all blunt trauma patients in general. Most of our patients underwent laparotomy (93.3%). The most common causes of death among patients with BDR were head injury (25.0%), intra-abdominal bleeding (23.3%) and pelvic hemorrhage (18.3%). Conclusion Blunt diaphragmatic rupture is rare and difficult to diagnose; however, certain MVC characteristics along with severe associated injuries should raise the index of suspicion. These associated injuries include injuries to the head, chest (including the aorta), abdomen and pelvis. Computed tomographic angiography is essential to rule out associated aortic injury and to increase the diagnostic accuracy of BDR. PMID:19503660

Patients with pre-injury coagulopathy have worse outcomes than those without coagulopathy. This article investigated the risk-adjusted effect of pre-injury coagulopathy on outcomes after splenic injuries. Review of the National Trauma Data Bank from 2007 to 2010 comparing mortality and complications between splenic injury patients with and without a pre-injury bleeding disorder. Of 58,896 patients, 2% had a bleeding disorder. Coagulopathic patients had higher odds of mortality (odds ratio, 1.3), sepsis (odds ratio, 2.0), acute respiratory distress syndrome (odds ratio, 2.6), acute renal failure (odds ratio, 1.5), cardiac arrest (odds ratio, 1.5), and overall complications (odds ratio, 2.4). The higher odds of myocardial infarction did not achieve statistical significance (odds ratio, 1.6). Pre-injury coagulopathy in patients with splenic injury has a negative impact on cardiac arrest, sepsis, acute respiratory distress syndrome, acute renal failure, and mortality. The higher likelihood of myocardial infarction did not reach statistical significance. Copyright © 2015 Elsevier Inc. All rights reserved.

Interventional radiology (IR) has become an integral part in the management of traumatic injuries. There is an ever-increasing role of IR in traumatic injuries of solid abdominal organs, pelvic and peripheral arteries to control active bleeding by therapeutic embolization or vascular reconstruction using stent grafts. Traditionally, these endovascular treatments have been offered to hemodynamically stable patients. However, in recent times endovascular approach has become preferable to surgery even in hemodynamically unstable patients with injury of surgically difficult-to-access sites. With shifting trends towards non operative management coupled with availability of the current state-of-the-art equipments, hardware and technical expertise, IR has gained an impeccable role in trauma management. However, due to lack of awareness and widespread acceptance, IR continues to remain an ocean of unexplored potentialities. PMID:28529680

The treatment of complex liver injuries remains a challenge. Nonoperative treatment for such injuries is increasingly being adopted as the initial management strategy. We reviewed our experience, at a University teaching hospital, in the nonoperative management of grade IV liver injuries with the intent to evaluate failure rates; need for angioembolization and blood transfusions; and in-hospital mortality and complications. This is a retrospective analysis conducted at a single large trauma centre in Brazil. All consecutive, hemodynamically stable, blunt trauma patients with grade IV hepatic injury, between 1996 and 2011, were analyzed. Demographics and baseline characteristics were recorded. Failure of nonoperative management was defined by the need for surgical intervention. Need for angioembolization and transfusions, in-hospital death, and complications were also assessed Eighteen patients with grade IV hepatic injury treated nonoperatively during the study period were included. The nonoperative treatment failed in only one patient (5.5%) who had refractory abdominal pain. However, no missed injuries and/or worsening of bleeding were observed during the operation. None of the patients died nor need angioembolization. No complications directly related to the liver were observed. Unrelated complications to the liver occurred in three patients (16.7%); one patient developed a tracheal stenosis (secondary to tracheal intubation); one had pleural effusion; and one developed an abscess in the pleural cavity. The hospital length of stay was on average 11.56 days. In our experience, nonoperative management of grade IV liver injury for stable blunt trauma patients is associated with high success rates without significant complications.

Severe lesions in the liver are associated with a high mortality rate. Alternative surgical techniques such as the use of an intrahepatic balloon may be effective and reduce mortality in severe hepatic lesions. This study aimed to demonstrate the experience of a university hospital in the use of the Sengstaken-Blakemore balloon in patients with transfixing penetrating hepatic injury as an alternative way to treat these challenging injuries. A retrospective study based on the trauma registry of a university hospital was performed. All patients admitted with hepatic penetrating injuries and treated with the Sengstaken-Blakemore balloon within the period 1990-2010 were reviewed. Forty-six patients with transfixing hepatic injuries were treated with the Sengstaken-Blakemore balloon in the study period. The most frequent cause of injury was gunshot wound (87 % of the patients). The mean trauma scores on admission were Revised Trauma Score (RTS) = 7.12 ± 1.46, Injury Severity Score (ISS) = 22.4 ± 9.7, and Abdominal Trauma Index (ATI) = 19.5 ± 11. According to the severity of the hepatic trauma, 71.8 % of patients had grade III, 23.9 % grade IV, and 4.3 % grade V injuries. Associated abdominal injuries were found in 89.1 % of the patients. The most frequent liver-related complications were hepatic abscess postoperative bleeding (8.6 %), biliary fistula (8.6 %), (4.3 %), and biliary peritonitis (2.1 %). Surgical reintervention was necessary in 14 patients (31.1 %). From those 14, only 3 had the balloon removed. The overall morbidity and mortality rates were 56.5 % and 23.9 % (11 patients), respectively. The knowledge of alternative surgical techniques is essential in improving survival in patients with severe penetrating hepatic injuries. The use of intrahepatic balloon is a viable surgical strategy.

Recombinant activated human coagulation factor VII (rFVIIa), an intravascular strategy to promote clotting, is being used as an adjunct to surgical control of bleeding in combat trauma patients. To describe the initial experiences with rFVIIa administered to combat casualties at US Navy-Marine Corps medical treatment facilities in Iraq, and to compare survival outcomes of those treated with rFVIIa to controls not receiving rFVIIa. Medical encounter data from the US Navy-Marine Corps Combat Trauma Registry were retrospectively reviewed to identify all battle-injured patients documented as having received rFVIIa during the period May 2004 to January 2006 of Operation Iraqi Freedom. Available clinical and injury related data are presented to characterise the patients. To assess effects of rFVIIa on survival outcomes, rFVIIa cases were matched to controls on injury severity and age. 22 battle-injured patients from the Combat Trauma Registry received rFVIIa. Primarily young US Marines, these patients typically had penetrating injuries from improvised explosive devices and gunshot wounds. Injuries were often abdominal. The average dose used was similar to that reported in another study of civilian trauma patients, although dosing varies widely in the existing experimental and anecdotal literature. Over two-thirds (68%) of the rFVIIa patients survived-an identical outcome seen for a matched control group of 22 patients. Survival of seriously injured combat casualties was good, although identical to that of a control group. Methodological limitations of this retrospective study preclude making firm conclusions about the effectiveness of rFVIIa. Future controlled studies are needed for safety and efficacy testing of rFVIIa in combat trauma patients.

Acute resuscitation of the unstable adult trauma patient: bedside diagnosis and therapy

2008-01-01

Traumatic injury remains the leading cause of potentially preventable death in Canadians under age 40 years. Although only a minority of patients present with hemodynamic instability, these patients have a significant chance of dying. The causes of instability must be recognized and corrected quickly by using a systematic approach. To allow key supportive interventions to be undertaken swiftly, it is more important to identify and prioritize systemic compromise than to confirm specific diagnoses. Most potentially preventable trauma death relates to airway obstruction, hemopneumothorax, intracranial hemorrhage and intracavitary bleeding. Definitive airway control should be assured as a first priority. Hemopneumothoraces are typically addressed by chest tube insertion, although thoracic exploration will occasionally be urgently required. Hemorrhage control is much more important than fluid resuscitation and mandates the earliest possible definitive management. Unstable patients nearing physiological exhaustion require abbreviated or “damage-control” surgical tactics. This should be recognized early in the resuscitation rather than late in an operative procedure. The management of expanding intracranial hemorrhage requires optimization of oxygenation, ventilation and circulatory support while urgent CT and expert neurosurgical care are provided. Polytrauma presenting with head injury challenges the most developed of trauma systems, necessitating thoughtful prioritization of care and taking into consideration local capabilities. Bedside trauma sonography is an evolving tool that complements the physical examination during an initial survey. Future breakthroughs in trauma resuscitation may involve procoagulant medications, imaging technology, circulatory assist techniques and the use of inflammatory modulators. The greatest future challenge in trauma care, though, will be the provision of basic organized resuscitative care to the global community. PMID:18248707

Pancreatic trauma: Universities of Melbourne HPB Group.

PubMed

Fleming, W R; Collier, N A; Banting, S W

1999-05-01

Pancreatic trauma is uncommon, but carries high morbidity and mortality rates, especially when diagnosis is delayed or inappropriate surgery is attempted. Although the retroperitoneal position of the pancreas confers it some immunity to injury, the force required to do so often results in severe associated injuries to other organs, which may be life threatening. Diagnosis may be difficult and surgery can be a considerable technical challenge. All patients with pancreatic trauma who attended one of three Melbourne teaching hospitals from 1977 to 1998 were identified. Injuries were graded and the method of diagnosis and treatment studied. The incidence and causation of postoperative morbidity and mortality was identified. Thirty-eight patients (26 men and 12 women) were studied. Blunt trauma was responsible in 30 patients, stab wounds in five, gunshot wounds in two and iatrogenic injury in one. Injuries to other organs occurred in 30 patients. Surgical procedures were undertaken in 34 patients, resulting in the death of five and complications in 25. Complications and death are related to the associated injuries, as much as to the pancreatic injury itself. In this study, we review the experience of the management of pancreatic trauma in three large teaching hospitals in Melbourne over a 21-year period, and suggest a strategy for dealing with these difficult patients. Adherence to the basic concepts of control of bleeding from associated vascular injury, minimization of contamination, accurate pancreatic assessment, judicious resection and adequate drainage can diminish the risk. By approaching the problem in a systematic way and adopting a generally conservative management plan, complications and deaths can be minimized in these complex cases.

Posterior urethra primary realignment (PUPR) after complete transection may decrease the gap between the ends of the transected urethra, tamponade the retropubic bleeding, and optimize urinary drainage without the need of suprapubic catheter facilitating concurrent pelvic orthopedic and trauma procedures. Historically, the distorted anatomy after pelvic trauma has been a major surgical challenge. The purpose of the study was to assess the relationship of the severity of the pelvic fracture to the success of endoscopic and immediate PUPR following complete posterior urethral disruption using the Young-Burgess classification system. A review of our Level I trauma center database for patients diagnosed with pelvic fracture and complete posterior urethral disruption from January 2005 to April 2012 was performed. Pelvic fracture severity was categorized according to the Young-Burgees classification system. Management consisted of suprapubic catheter insertion at diagnosis followed by early urethral realignment when the patient was clinically stable. Failure of realignment was defined as inability to achieve urethral continuity with Foley catheterization. Clinical follow-up consisted of radiologic, pressure studies and cystoscopic evaluation. A total of 481 patients with pelvic trauma from our trauma registry were screened initially, and 18 (3.7%) were diagnosed with a complete posterior urethral disruption. A total of 15 primary realignments (83.3%) were performed all within 5 days of trauma. The success rate of early realignment was 100%. There was no correlation between the type of pelvic ring fracture and the success of PUPR. Postoperatively, 8 patients (53.3%) developed urethral strictures, 3 patients (20.0%) developed incontinence, and 7 patients (46.7%) reported erectile dysfunction after the trauma. The mean follow-up of these patients was 31.8 months. Endoscopic PUPR may be an effective option for the treatment of complete posterior urethral disruption and enables urinary drainage to best suit the multispecialty surgical team. The success rate of achieving primary realignment did not appear to be related to the complexity and type of pelvic ring fracture.

The Trauma Hemostasis and Oxygenation Research Network held its third annual Remote Damage Control Resuscitation Symposium in June 2013 in Bergen, Norway. The Trauma Hemostasis and Oxygenation Research Network is a multidisciplinary group of investigators with a common interest in improving outcomes and safety in patients with severe traumatic injury. The network's mission is to reduce the risk of morbidity and mortality from traumatic hemorrhagic shock, in the prehospital phase of resuscitation through research, education, and training. The concept of remote damage control resuscitation is in its infancy, and there is a significant amount of work that needs to be done to improve outcomes for patients with life-threatening bleeding secondary to injury. The prehospital phase of resuscitation is critical in these patients. If shock and coagulopathy can be rapidly identified and minimized before hospital admission, this will very likely reduce morbidity and mortality. This position statement begins to standardize the terms used, provides an acceptable range of therapeutic options, and identifies the major knowledge gaps in the field.

Gastrointestinal bleeding and obstructive jaundice: Think of hepatic artery aneurysm.

Hemobilia is an uncommon and potential life-threatening condition mainly due to hepato-biliary tree traumatic or iatrogenic injuries. Spontaneously ruptured aneurysm of the hepatic artery is seldom described. We report the case of an 89-year-old woman presenting with abdominal pain, jaundice and gastrointestinal bleeding, whose ultrasound and computed tomography revealed a non-traumatic, spontaneous aneurysm of the right hepatic artery. The oeso-gastro-duodenoscopy and colonoscopy did not reveal any bleeding at the ampulla of Vater, nor anywhere else. Selective angiography confirmed the diagnosis of hepatic artery aneurysm and revealed a full hepatic artery originating from the superior mesenteric artery. The patient was successfully treated by selective embolization of microcoils. We discuss the etiologies of hemobilia and its treatment with selective embolization, which remains favored over surgical treatment. Although aneurysm of the hepatic artery is rare, especially without trauma, a high index of suspicion is needed in order to ensure appropriate treatment.

Form 732 Trauma, 356(48.6%) of patients were submitted to a surgical procedure, all the other patient 376(51.4%) underwent an non operative management .Overall mortality was 9.8% (72), mortality in the surgery group was 15.4% eheras in the non operative group was 4.5%; the relative risk of mortality, measured by the odds ratio waith a 95% confidence interval, was 3.417(2.023-5.772) for rhe surgery group; patient over 40 years old has a statistically significant higher mortality. In our series the overall mortality rate of non operative management group was 4.5%, instead in unstable patients, the surgery group, the mortality was 15.3%; the overall mortality mortality rate after the application of our protocol is 9.8%, Although surgery continues to be the standard for hemodically unstable patients with blunt hepatic and splenic trauma. In our experience AAST Organ Injury Scale was useless for the therapeutic decision making process after the CT scan if a source of bleeding was detected and immediate angiography was performed in order to control and solve it. In our experience the AAST Organ Injury Scale was useless for the therapeutic decision making process, The results suggest that the only criteria of choice for therapeutici strategy was the hemodynamic stability, Nonoperative managem,ent can be applied only following strict institutional criteria KEY WORDS: Hemodynmic stability, Nonoperative management, Trauma.

Laboratory-based evidence of coagulopathy (LC) is observed in 25-35% of trauma patients, but clinically-evident coagulopathy (CC) is not well described. Prospective observational study of adult trauma patients transported by helicopter from the scene to nine Level 1 trauma centers in 2015. Patients meeting predefined highest-risk criteria were divided into CC+ (predefined as surgeon-confirmed bleeding from uninjured sites or injured sites not controllable by sutures) or CC-. We used a mixed-effects, Poisson regression with robust error variance to test the hypothesis that abnormalities on rapid thrombelastography (r-TEG) and international normalized ratio (INR) were independently associated with CC+. Of 1,019 highest-risk patients, CC+ (n=41, 4%) were more severely injured (median ISS 32 vs 17), had evidence of LC on r-TEG and INR, received more transfused blood products at 4 hours (37 vs 0 units), and had greater 30-day mortality (59% vs 12%) than CC- (n=978, 96%). The overall incidence of LC was 39%. 30-day mortality was 22% vs 9% in those with and without LC. In two separate models, r-TEG K-time >2.5 min (RR 1.3, 95% CI 1.1-1.7), r-TEG mA <55 mm (RR 2.5, 95% CI 2.0-3.2), platelet count <150 x 10 9 /L (RR 1.2, 95% CI 1.1-1.3), and INR >1.5 (RR 5.4, 95% CI 1.8-16.3) were independently associated with CC+. A combined regression model was not generated because too few patients underwent both r-TEG and INR. CC was rare compared to LC. CC was associated with poor outcomes and impairment of both clotting factor and platelet-mediated coagulation components. Copyright © 2017 Elsevier Inc. All rights reserved.

Emergency department care for patients with hemophilia and von Willebrand disease.

Singleton, Tammuella; Kruse-Jarres, Rebecca; Leissinger, Cindy

2010-08-01

Patients with bleeding disorders such as hemophilia A, hemophilia B, and von Willebrand disease (VWD) are routinely treated at home, with their care managed in specialized centers. In emergency situations, these patients often present to their local emergency department (ED), where their management can represent a challenge to the emergency physicians and staff who rarely encounter them. Delays in diagnosis and administration of replacement therapy are the factors most commonly identified as predictive of death. Patients and family members are often very well educated in the disease and its management, which can significantly reduce morbidity and mortality. Children with bleeding disorders confer different challenges to the emergency physician and staff: they may present with no obvious signs of trauma or they may present with bruises consistent with non-accidental injury. All possible causes of bruising/bleeding should be investigated, although treatment should be administered promptly. The initial presentation of a bleeding disorder in the pediatric population is often made in the ED. Treatment of hemophilia A and B requires rapid replacement of the deficient clotting factor, with the desired factor level and dosage dependent on the product used and the hemorrhagic situation encountered. In patients with VWD, the main treatments are desmopressin or intravenous infusion of plasma-derived concentrates containing factor VIII and von Willebrand factor. The aim of this review is to outline some of the issues facing emergency physicians and the options available for the treatment of patients with hemophilia A, hemophilia B, and VWD. Copyright 2010.

2014-04-03

A patient presented with profuse bleeding from the oronasal cavity following orofaciomaxillary trauma associated with tracheolaryngeal injury and suspected cervical-spine injury due to collapse of a wall on the face, neck and upper chest. The patient was gasping, coughing blood and was unable to speak. Threatened airway was diagnosed. Inability to maintain oxygenation on cricothyroidotomy, forced emergency department surgeons to shift the patient to the operating room for definitive airway. During tracheostomy a major vessel was injured. Application of vascular clamp in the event of achieving haemostasis resulted in disappearance of saturation and pulse in the right upper limb, thus we suspected innominate artery (IA) injury. High tracheostomy performed and endotracheal tube passed into the trachea after removing clot and overcoming compromised narrow tracheal lumen. The injured IA was repaired and the patient survived for 14 days. On postoperative day 14 he died following profound bleeding into the tracheobronchial tree and asphyxia/apnoea. Tracheoinnominate artery fistula was detected at autopsy.

Report of a rare case: occult hemothorax due to blunt trauma without obvious injury to other organs

2013-01-01

Traumatic hemothorax commonly occurs accompanied by organ damage, such as rib fractures, lung injury and diaphragm rupture. Our reported patient was a 61-year-old man who fell down from a stepladder about 1 meter in height, resulting in a heavy blow to the left abdomen. He consulted a clinic because of left chest pain the next day and was transported to the emergency center of our hospital on diagnosis of hemothorax with hemorrhagic shock. On computed tomography scanning with contrast medium, left hemothorax without rib fracture, diaphragm rupture or obvious organ injury was evident. We found only bleeding to the thoracic space from a branch of the left inferior phrenic artery without involvement of the abdomen. The patient underwent percutaneous angiography and embolization for hemostasis, and subsequently thoracotomy in order to check the active bleeding and remove the hematoma to improve respiratory. As thoracotomy findings, we found damage of a branch of the left inferior phrenic artery to the thoracic space without diaphragm rupture, and sutured the lesion. Such active intervention followed by surgical procedures was effective and should be considered for rare occurrences like the present case. We must consider not only traumatic diaphragm rupture, but also vascular damage by pressure trauma as etiological factors for hemothorax. PMID:24176006

Traumatic injury is the leading cause of potentially preventable lost years of life in the Western world and exsanguination is the most potentially preventable cause of post-traumatic death. With mature trauma systems and experienced trauma centres, extra-abdominal sites, such as the pelvis, constitute the most frequent anatomic site of exsanguination. Haemorrhage control for such bleeding often requires surgical adjuncts most notably interventional radiology (IR). With the usual paradigm of surgery conducted within an operating room and IR procedures within distant angiography suites, responsible clinicians are faced with making difficult decisions regarding where to transport the most physiologically unstable patients for haemorrhage control. If such a critical patient is transported to the wrong suite, they may die unnecessarily despite having potentially salvageable injuries. Thus, it seems only logical that the resuscitative operating room of the future would have IR capabilities making it the obvious geographic destination for critically unstable patients, especially those who are exsanguinating. Our trauma programme recently had the opportunity to conceive, design, build, and operationalise a purpose-designed hybrid trauma operating room, designated as the resuscitation with angiographic percutaneous techniques and operative resuscitation (RAPTOR) suite, which we believe to be the first such resource designed primarily to serve the exsanguinating trauma patient. The project was initiated after consultations between the trauma programme and private philanthropists regarding the greatest potential impacts on regional trauma care. The initial capital construction costs were thus privately generated but coincided with a new hospital wing construction allowing the RAPTOR to be purpose-designed for the exsanguinating patient. Many trauma programmes around the world are now starting to navigate the complex process of building new facilities, or else retrofitting existing ones, to address the need for single-site flexible haemorrhage control. This manuscript therefore describes the many considerations in the design and refinement of the physical build, equipment selection, human factors evaluation of new combined treatment paradigms, and the final introduction of a RAPTOR protocol in order that others may learn from our initial efforts.

PURPOSE Intrahepatic portal vein injuries secondary to blunt abdominal trauma are difficult to diagnose and can result in insidious bleeding. We aimed to compare computed tomography arterial portography (CTAP), reperfusion CTAP (rCTAP), and conventional computed tomography (CT) for diagnosing portal vein injuries after blunt hepatic trauma. METHODS Patients with blunt hepatic trauma, who were eligible for nonoperative management, underwent CTAP, rCTAP, and CT. The number and size of perfusion defects observed using the three methods were compared. RESULTS A total of 13 patients (seven males/six females) with a mean age of 34.5±14.1 years were included in the study. A total of 36 hepatic segments had perfusion defects on rCTAP and CT, while there were 47 hepatic segments with perfusion defects on CTAP. The size of perfusion defects on CT (239 cm3; interquartile range [IQR]: 129.5, 309.5) and rCTAP (238 cm3; IQR: 129.5, 310.5) were significantly smaller compared with CTAP (291 cm3; IQR: 136, 371) (both, P = 0.002). CONCLUSION Perfusion defects measured by CTAP were significantly greater than those determined by either rCTAP or CT in cases of blunt hepatic trauma. This finding suggests that CTAP is superior to rCTAP and CT in evaluating portal vein injuries after blunt liver trauma. PMID:26268303

Overview of platelet physiology and laboratory evaluation of platelet function.

Rodgers, G M

Appropriate laboratory testing for the platelet-type bleeding disorders hinges on an adequate assessment in the history and physical examination. Patients with histories and screening laboratory results consistent with coagulation disorders (hemophilia, disseminated intravascular coagulation) are not appropriate candidates for platelet function testing. In contrast, patients with a lifelong history of platelet-type bleeding symptoms and perhaps a positive family history of bleeding would be appropriate for testing. Figure 6 depicts one strategy to evaluate these patients. Platelet morphology can easily be evaluated to screen for two uncommon qualitative platelet disorders: Bernard-Soulier syndrome (associated with giant platelets) and gray platelet syndrome, a subtype of storage pool disorder in which platelet granulation is morphologically abnormal by light microscopy. If the bleeding disorder occurred later in life (no bleeding with surgery or trauma early in life), the focus should be on acquired disorders of platelet function. For those patients thought to have an inherited disorder, testing for vWD should be done initially because approximately 1% of the population has vWD. The complete vWD panel (factor VIII coagulant activity, vWf antigen, ristocetin cofactor activity) should be performed because many patients will have abnormalities of only one particular panel component. Patients diagnosed with vWD should be classified using multimeric analysis to identify the type 1 vWD patients likely to respond to DDAVP. If vWD studies are normal, platelet aggregation testing should be performed, ensuring that no antiplatelet medications have been ingested at least 1 week before testing. If platelet aggregation tests are normal and if suspicion for an inherited disorder remains high, vWD testing should be repeated. The evaluation of thrombocytopenia may require bone marrow examination to exclude primary hematologic disorders. If future studies with thrombopoietin assays confirm preliminary results, however, the bone marrow examination of certain patients may be replaced by a thrombopoietin level.

Hospital-wide massive transfusion protocols (MTPs) primarily designed for trauma patients may lead to excess blood products being prepared for nontrauma patients. This study characterized blood product utilization among distinct trauma and nontrauma MTPs at a large, urban academic medical center. A retrospective study of blood product utilization was conducted in patients who required an MTP activation between January 2011 and December 2015 at an urban academic medical center. Trauma MTP containers included 6 red blood cell (RBC) units, 5 plasma units, and 1 unit of apheresis platelets. Nontrauma MTP containers included 6 RBC and 3 plasma units. There were 334 trauma MTP activations, 233 nontrauma MTP activations, and 77 nontrauma MTP activations that subsequently switched to a trauma MTP ("switched activations"). All nontrauma MTP activations were among bleeding patients who did not have a traumatic injury (100% [233/233]). Few patients with a nontrauma activation required ad hoc transfusion of RBC units (1.3% [95% confidence interval {CI}, 0.3%-3.7%]) or plasma (3.4% [95% CI, 1.5%-6.7%]), and only 45.5% (95% CI, 39.0%-52.1%) required ad hoc transfusion of apheresis platelets. Compared to trauma and switched activations, nontrauma activations transfused a lower median number of RBC, plasma, and apheresis platelet units (P < .001 for all comparisons). There was also a lower median number of prepared but unused plasma units for nontrauma activations (3; [interquartile range {IQR}, 3-5]) compared to trauma (7; [IQR, 5-10]; P < .001) and switched activations (8; [IQR, 5-11]; P < .001). The median number of unused apheresis platelet units was 1 (IQR, 1-2) for trauma activations and 0 (IQR, 0-1) for switched activations. There was a high proportion of trauma and switched activations in which all of the prepared apheresis platelet units were unused (28.1% [95% CI, 23.4%-33.3%] and 9.1% [95% CI, 3.7%-17.8%], respectively). The majority of initial nontrauma MTP activations did not require a switch to a trauma MTP. Patients remaining under a nontrauma MTP activation were associated with a lower number of transfused and unused plasma and apheresis platelet units. Future studies evaluating the use of hospital-wide nontrauma MTPs are warranted since an MTP designed for nontrauma patient populations may yield a key strategy to optimize blood product utilization in comparison to a universal MTP for both trauma and nontrauma patients.

Background : The liver is the most injured organ in abdominal trauma. Currently, the treatment in most cases is non-operative, but surgery may be necessary in severe abdominal trauma with blunt liver damage, especially those that cause uncontrollable bleeding. Despite the damage control approaches in order to achieve hemodynamic stability, many patients develop hypovolemic shock, acute liver failure, multiple organ failure and death. In this context, liver transplantation appears as the lifesaving last resource Aim : Analyze the use of liver transplantation as a treatment option for severe liver trauma. Methods : Were reviewed 14 articles in the PubMed, Medline and Lilacs databases, selected between 2008-2014 and 10 for this study. Results : Were identified 46 cases undergoing liver transplant after liver trauma; the main trauma mechanism was closed/blunt abdominal trauma in 83%, and severe trauma (>grade IV) in 81 %. The transplant can be done, in this context, performing one-stage procedure (damaged organ removed with immediate transplantation), used in 72% of cases. When the two-stage approach is performed, end-to-side temporary portacaval shunt is provided, until new organ becomes available to be transplanted. If two different periods are considered - from 1980 to 2000 and from 2000 to 2014 - the survival rate increased significantly, from 48% to 76%, while the mortality decreased from 52% to 24%. Conclusion : Despite with quite restricted indications, liver transplantation in hepatic injury is a therapeutic modality viable and feasible today, and can be used in cases when other therapeutic modalities in short and long term, do not provide the patient survival chances.

Nonoperative management for patients with grade IV blunt hepatic trauma

PubMed Central

2012-01-01

Introduction The treatment of complex liver injuries remains a challenge. Nonoperative treatment for such injuries is increasingly being adopted as the initial management strategy. We reviewed our experience, at a University teaching hospital, in the nonoperative management of grade IV liver injuries with the intent to evaluate failure rates; need for angioembolization and blood transfusions; and in-hospital mortality and complications. Methods This is a retrospective analysis conducted at a single large trauma centre in Brazil. All consecutive, hemodynamically stable, blunt trauma patients with grade IV hepatic injury, between 1996 and 2011, were analyzed. Demographics and baseline characteristics were recorded. Failure of nonoperative management was defined by the need for surgical intervention. Need for angioembolization and transfusions, in-hospital death, and complications were also assessed Results Eighteen patients with grade IV hepatic injury treated nonoperatively during the study period were included. The nonoperative treatment failed in only one patient (5.5%) who had refractory abdominal pain. However, no missed injuries and/or worsening of bleeding were observed during the operation. None of the patients died nor need angioembolization. No complications directly related to the liver were observed. Unrelated complications to the liver occurred in three patients (16.7%); one patient developed a tracheal stenosis (secondary to tracheal intubation); one had pleural effusion; and one developed an abscess in the pleural cavity. The hospital length of stay was on average 11.56 days. Conclusions In our experience, nonoperative management of grade IV liver injury for stable blunt trauma patients is associated with high success rates without significant complications.

Rapid and accurate determination of prothrombin time in trauma patients may help to faster control of bleeding induced coagulopathy. The goal of this prospective observational study was to investigate the accuracy of bedside measurements of prothrombin time by the mean of a point-of-care device (INRatio) in trauma patients. Fifty blood samples were drawn at admission and during the acute care phase for standard coagulation assays (prothrombin time, International Normalized Ratio [INR], and fibrinogen) and INRatio testing (INR(A)) from 48 trauma patients. Standard coagulation assays were available after a mean of 66 minutes. Median Injury Severity Score was 18, and 16 patients (33%) had a coagulopathy. Significant correlation was found between INR and INR(A) (r: 0.93, 95% confidence interval: 0.87-0.96). The mean difference (bias) for INR was 0.00, and standard deviation (precision) of the difference was 0.78. However, in cases where there was decreased hemoglobin (<10 gr · L(-1)) and fibrinogen (<1.5 gr · L(-1)), bias and precision were increased. To predict the need for fresh frozen plasma transfusion (INR > 1.5), INR(A) cutoff value of 1.3 resulted in a sensitivity of 92% and a specificity of 79%. The area under the receiver operating characteristic curve was 0.946 (95% confidence interval: 0,845-0,982). INRatio may be a useful device in the management of trauma patients with ongoing or suspected coagulopathy that may help to save at least 60 minutes in the process of obtaining a prothrombin time result. It may allow earlier detection of coagulopathy and, together with vital sign and hemoglobin, may help to guide fresh frozen plasma transfusion.

Risk for bleeding complications during and after early hip fracture surgery for patients taking clopidogrel and other anticoagulants have not been defined. The purpose of this study is to assess the perioperative bleeding risks and clinical outcome after early hip fracture surgery performed on patients taking clopidogrel (Plavix) and other oral anticoagulants. Study design is a retrospective cohort analysis using data extracted from hospital records and state death records. Regional medical center (level II trauma). Data for 1118 patients ≥60 years of age who had surgical treatment for a hip fracture between 2004 and 2008 were reviewed. Eighty-two patients undergoing late surgery (>3 days after admission) were excluded. Patients taking clopidogrel were compared against those not taking clopidogrel. In addition, patients taking clopidogrel only were compared against cohorts of patients taking both clopidogrel and aspirin, aspirin only, warfarin only, or no anticoagulant. Seventy-four of 1036 patients (7%) were taking clopidogrel, although control groups included 253 patients on aspirin alone, 90 patients on warfarin, and 619 taking no anticoagulants. No significant differences were noted between patients taking clopidogrel and those not taking clopidogrel in estimated blood loss, transfusion requirement, final blood count, hematoma evacuation, hospital length of stay (LOS), or mortality while in hospital or at 1 year. A higher American Society of Anesthesiologists score was seen in the clopidogrel and warfarin groups (P = 0.05 each), increased LOS in the clopidogrel group (P = 0.05), and higher rate of deep vein thrombosis seen in those patients taking warfarin (P = 0.05). Clopidogrel only versus aspirin versus both aspirin and clopidogrel, versus no anticoagulant versus warfarin showed no significant differences in estimated blood loss, transfusion requirement, final blood count, bleeding or perioperative complications, or mortality. Patients undergoing early hip fracture surgery who are taking clopidogrel, aspirin, or warfarin (with regulated international normalized ratio) are not at substantially increased risk for bleeding, bleeding complications, or mortality. Comorbidities and American Society of Anesthesiologists scores were significantly higher in the clopidogrel group, which may have resulted in the increased postoperative LOS in this group.

In recent years, the treatment of trauma-associated coagulopathy and bleeding has advanced enormously. The aim of this study was to assess the current practice of coagulation and transfusion management in Germany. From October 2011 until January 2012 we conducted a survey via online-questionnaire that was sent per E-Mail to all members of the German Society for Trauma Surgery. It comprised 12 questions with respect to current treatment of coagulopathy and haemorrhage in trauma patients. The response rate was 145/3006 (5 %). The respondents had following specialties: 77.2 % trauma surgery 15.9 % anesthesiology, 6.9 % others. 64 % of respondents were employed by a Level 1 trauma centre, wheras 17 % worked in a local level 3 centre. The majority (94 %) claimed to treat hypothermia regularly. Only about half of the participants reported to follow a massive transfusion protocol in their institution. The potential components of these protocols were reported in varying rates, being it well-established components (e.g. FFP 78 %; Fibrinogen 75 %) or therapies with poor evidence in multiple trauma (Desmopressin 39 %, rFVIIa 47 %). Calcium was provided by only 48 % of respondents although generally recommended in all guidelines. The current study suggests that in Germany strategies and principles regarding management of trauma-associated coagulopathy are standardized only poorly. Level 1 centres appear to apply a more advanced approach, however to much variability exists with respect to the components of the transfusion protocols. The low response rate indicates that most German trauma surgeons consider coagulation and hemorrhage as "expert-topics" beyond their field of duty.

Chromogenic Factor VIII Assays for Improved Diagnosis of Hemophilia A.

PubMed

Rodgers, Susan; Duncan, Elizabeth

2017-01-01

Hemophilia A is an inherited bleeding disorder caused by a reduced level of factor VIII coagulant activity (FVIII:C) in blood. Bleeding episodes may occur spontaneously in the severe form of hemophilia or after trauma in the milder forms. It is important that patients are diagnosed correctly, which includes placing them into the correct severity category of the disorder so that appropriate treatment can be given. Diagnosis is made by determination of the amount of FVIII:C in the blood, usually using a one-stage factor VIII:C assay. However, approximately one third of patients with mild or moderate hemophilia will have much lower results by the chromogenic assay, with some of them having normal results by the one-stage assay. The chromogenic factor VIII assay is used in some specialized hemophilia reference centers and is recommended for the diagnosis of mild hemophilia A, as this assay is considered to better reflect the severity status of hemophilia patients than the one-stage assay.

The aim of this study was to assess the change in trends in the management of traumatic brain injury (TBI) at a level I trauma center and the utilization of resources as a result of this change in management. The management of TBI has been evolving with trends toward management of minimally injured patients with intracranial hemorrhage exclusively by trauma surgeons. A 5-year (2009-2014) prospective database on all patients with TBI (skull fracture/intracranial hemorrhage on head computed tomography) presenting to a level I trauma center was analyzed for patient demographics, injuries, admission physiology, computed tomographic scan results, and hospital outcomes. These records were matched to the institutional registry and hospital financial database. A total of 2184 patients were included with median (interquartile range) Glasgow Coma Scale score of 15 (12-15), and median (interquartile range) head-abbreviated injury scale score of 3 (2-4). The distribution of types and size of intracranial bleeds remained unchanged throughout the study period. The proportion of TBI managed exclusively by trauma surgeons increased significantly over the years from 6.8% to 40.1% (P < 0.001). Proportion of patients who received neurosurgical consultations (P < 0.001) and repeat head computed tomographic scans (P < 0.001), hospital length of stay (P = 0.028), and costs (P < 0.001) decreased significantly over time. The overall mortality rate (18.5%) and rate of intervention (14.1%) remained unchanged. TBI patients can be selectively managed without initially involving neurosurgeons safely in a cost-effective manner, resulting in more effective use of precious resources.

Literature review of non-operative management of patients with blunt splenic injury: impact of splenic artery embolization

Splenic injuries constitute the most common injuries accompanying blunt abdominal traumas. Non-operative treatment is currently the standard for treating hemodynamically stable patients with blunt splenic injuries. The introduction of splenic angiography has increased the possibility of non-operative treatment for patients who, in the past, would have qualified for surgery. This cohort includes mainly patients with severe splenic injuries and with active bleeding. The results have indicated that applying splenic angioembolization reduces the frequency of non-operative treatment failure, especially in severe splenic injuries; however, it is still necessary to perform prospective, randomized clinical investigations.

The Scottish Transfusion and Laboratory Support in Trauma Group (TLSTG) have introduced a unified National pre-hospital Code Red protocol. This paper reports the results of a study aiming to establish whether current pre-hospital Code Red activation criteria for trauma patients successfully predict need for in hospital transfusion or haemorrhagic death, the current admission coagulation profile and Concentrated Red Cell (CRC): Fresh Frozen Plasma (FFP) ratio being used, and whether use of the protocol leads to increased blood component discards? Prospective cohort study. Clinical and transfusion leads for each of Scotland's pre-hospital services and their receiving hospitals agreed to enter data into the study for all trauma patients for whom a pre-hospital Code Red was activated. Outcome data collected included survival 24h after Code Red activation, survival to hospital discharge, death in the Emergency Department and death in hospital. Between June 1st 2013 and October 31st 2015 there were 53 pre-hospital Code Red activations. Median Injury Severity Score (ISS) was 24 (IQR 14-37) and mortality 38%. 16 patients received pre-hospital blood. The pre-hospital Code Red protocol was sensitive for predicting transfusion or haemorrhagic death (89%). Sensitivity, specificity, positive and negative predictive values of the pre-hospital SBP <90mmHg component were 63%, 33%, 86% and 12%. 19% had an admission prothrombin time >14s and 27% had a fibrinogen <1.5g/L. CRC: FFP ratios did not drop to below 2:1 until 150min after arrival in the ED. 16 red cell units, 33 FFP and 6 platelets were discarded. This was not significantly increased compared to historical data. A National pre-hospital Code Red protocol is sensitive for predicting transfusion requirement in bleeding trauma patients and does not lead to increased blood component discards. A significant number of patients are coagulopathic and there is a need to improve CRC: FFP ratios and time to transfusion support especially FFP provision. Training clinicians to activate pre-hospital Code Red earlier during the pre-hospital phase may give blood bank more time to thaw and prepare FFP and may improve FFP administration times and ratios so long as components are used upon their availability.

The objective of our study was to report the management and follow-up of a particular case of ballistic trauma and to do the literature review. A 35-year-old patient, a trader who was the victim of a firearm accident under not very clear circumstances. He was admitted to the emergency department after 3 hours. Clinically, the patient had significant bleeding in the arm and was in a state of clouding of consciousness. We could notice on the right arm, a posterior large transfixing wound of 1 cm and a 6 cm one on the antero-internal side. The limb was cold with a small and thready pulse. Sensitivity was decreased in the radial nerve area. The radiograph showed bone comminution from the middle 1/3 to the superior 1/3 of the humeral diaphysis. The treatment was orthopedic (after debridement) by scapula-brachio-ante-brachiopalmar plaster splint with thoracic strap. The wound healed in 46 days and the patient resumed his activities after 11 months and 2 weeks. The authors presented the value of using the scapulo-brachio-palmar plaster splints with thoracic strap in some severe upper limb trauma in the absence of the external fixator.

Physical trauma affects 1 in 12 pregnant women and has a major impact on maternal mortality and morbidity and on pregnancy outcome. A multidisciplinary approach is warranted to optimize outcome for both the mother and her fetus. The aim of this document is to provide the obstetric care provider with an evidence-based systematic approach to the pregnant trauma patient. Significant health and economic outcomes considered in comparing alternative practices. Published literature was retrieved through searches of Medline, CINAHL, and The Cochrane Library from October 2007 to September 2013 using appropriate controlled vocabulary (e.g., pregnancy, Cesarean section, hypotension, domestic violence, shock) and key words (e.g., trauma, perimortem Cesarean, Kleihauer-Betke, supine hypotension, electrical shock). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English between January 1968 and September 2013. Searches were updated on a regular basis and incorporated in the guideline to February 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). This guideline is expected to facilitate optimal and uniform care for pregnancies complicated by trauma. Summary Statement Specific traumatic injuries At this time, there is insufficient evidence to support the practice of disabling air bags for pregnant women. (III) Recommendations Primary survey 1. Every female of reproductive age with significant injuries should be considered pregnant until proven otherwise by a definitive pregnancy test or ultrasound scan. (III-C) 2. A nasogastric tube should be inserted in a semiconscious or unconscious injured pregnant woman to prevent aspiration of acidic gastric content. (III-C) 3. Oxygen supplementation should be given to maintain maternal oxygen saturation > 95% to ensure adequate fetal oxygenation. (II-1B) 4. If needed, a thoracostomy tube should be inserted in an injured pregnant woman 1 or 2 intercostal spaces higher than usual. (III-C) 5. Two large bore (14 to 16 gauge) intravenous lines should be placed in a seriously injured pregnant woman. (III-C) 6. Because of their adverse effect on uteroplacental perfusion, vasopressors in pregnant women should be used only for intractable hypotension that is unresponsive to fluid resuscitation. (II-3B) 7. After mid-pregnancy, the gravid uterus should be moved off the inferior vena cava to increase venous return and cardiac output in the acutely injured pregnant woman. This may be achieved by manual displacement of the uterus or left lateral tilt. Care should be taken to secure the spinal cord when using left lateral tilt. (II-1B) 8. To avoid rhesus D (Rh) alloimmunization in Rh-negative mothers, O-negative blood should be transfused when needed until cross-matched blood becomes available. (I-A) 9. The abdominal portion of military anti-shock trousers should not be inflated on a pregnant woman because this may reduce placental perfusion. (II-3B) Transfer to health care facility 10. Transfer or transport to a maternity facility (triage of a labour and delivery unit) is advocated when injuries are neither life- nor limb-threatening and the fetus is viable (≥ 23 weeks), and to the emergency room when the fetus is under 23 weeks' gestational age or considered to be non-viable. When the injury is major, the patient should be transferred or transported to the trauma unit or emergency room, regardless of gestational age. (III-B) 11.

Obturator artery injury (OAI) from pelvic gunshot wounds (GSW) is a rarely reported condition. Hemorrhages from pelvic trauma (PT) are mostly venous. Arterial hemorrhages represent about 10-20% of PTs. When arterial hemorrhages from PT occur, they are a severe and deadly complication often causing significant hemodynamic instability and eventual shock. A  23-year-old male presented to our emergency service via a private vehicle with multiple gunshot wounds to both thighs and to the lower back, resulted in rectal and obturator artery (OA) injuries. The patient underwent a successful coil-embolization of the right OA. Given the density of structures within the pelvis, patients who sustain gunshot wounds to the pelvic region are at high risk for injury to the small bowel, sigmoid colon, rectum, bladder, and/or vascular structures. While bleeding is the major cause of early mortality in PT, rectal injuries carry the highest mortality due to visceral injuries. A high clinical index of suspicion is needed to diagnose an iliac artery injury or injury to its branches. Prompt computed tomographic angiogram (CTA) and embolization of the OA is the best method to control and stop the bleeding and improve the mortality outcome. Clinicians caring for patients presenting with pelvic gunshot wounds should pay attention to the delayed presentation of internal hemorrhage from the OAs. A multidisciplinary team approach is crucial in the successful management of penetrating injuries to the obturator artery.

Spontaneous retroperitoneal hematoma (SRH) is a potentially fatal clinical entity requiring immediate recognition and intervention. The clinical records of 18-year-old and older patients admitted to the University Hospital Marqués de Valdecilla from 2003 to 2013 were reviewed. "Spontaneous" was defined as unrelated to trauma, invasive procedures or bleeding due to aortic aneurysm rupture. Thirty-four patients with SRH (44% were on anticoagulant drugs). One-third of cases had chronic renal insufficiency. Abdominal pain was the most common symptom both in anticoagulated and non-anticoagulated patients (80% in anticoagulated and 89% in non-anticoagulated patients). About one half of the patients developed shock. A CT scan was the most commonly performed diagnostic test, followed by abdominal ultrasound. Most cases were managed conservatively (80%). More than half of the patients (66%) restarted anticoagulation therapy after the acute event with a mean delay of 19 days (range 2-90 days). None of them suffered a new bleeding episode. Restarting the anticoagulation treatment after hematoma resolution seems to be a safe practice. There is an increasing frequency of SRH in non-anticoagulated patients.

Venous thromboembolic disease is a significant source of morbidity and mortality in hospitalized trauma patients. Multiple drugs and dosing regimens have been suggested for pharmacoprophylaxis. In this study, we compared efficacy, complications, and cost of unfractionated heparin administered subcutaneously three times a day with standard-dosed enoxaparin for prophylaxis of deep venous thrombosis (DVT) in adult trauma patients over 1 year. Patients admitted for greater than 72 hours who received pharmacoprophylaxis as part of a comprehensive DVT protocol were included. A change was made in the protocol from enoxaparin (30 mg twice a day or 40 mg per day) to heparin (5000 U three times a day) at midyear. Surveillance lower extremity venous ultrasound was performed according to established institutional guidelines. Data, including demographics, associated injuries, complications, and cost, were collected and analyzed. Four hundred seventy-six patients met inclusion criteria. Two hundred thirty-seven (49.8%) patients received enoxaparin and 239 (50.2%) received heparin. Proximal lower extremity DVTs were detected in 16 (6.75%) patients in the enoxaparin group and 17 (7.11%) in the heparin group (P = 0.999). Risk factors for DVT in these patients included spinal cord injury (P = 0.001) and closed head injury (P = 0.031). There was no difference between the incidence of pulmonary emboli and bleeding. There was an estimated yearly pharmacy cost savings of $135,606. In trauma patients, subcutaneous heparin dosed three times a day may be as effective as standard-dosed enoxaparin for prophylaxis of venous thromboembolism without increased complications. Heparin three times a day for venous thromboembolism prophylaxis was associated with significant pharmaceutical cost savings.

Polyarteritis nodosa (PAN) can affect many organ systems but usually presents with a systemic illness characterised by malaise, weight loss, myalgia, arthralgia and signs of end-organ damage. Here, we report a case of PAN that presented acutely in a previously well 46-year-old man with visible haematuria and loin pain coinciding with an episode of strenuous exercise. Initially, the patient was thought to have suffered renal trauma, but subsequent investigations revealed intrarenal aneurysms typical of PAN which responded to immunosuppressive therapy. This case illustrates the importance of appropriate imaging for suspected urogenital tract trauma, that a high index of suspicion is required to make the diagnosis and that PAN can present with renal tract bleeding in the absence of obvious systemic features.

Haemorrhagic diathesis has been of much concern to health professionals including dentists. It is not infrequent that a dentist becomes the first person to diagnose a bleeding disorder while performing dental treatment. Haemophilia is an X linked disorder with a frequency of about 1:10 000 births. Haemophilia B is much less common than haemophilia A, and affects only 1:300 000 males born alive. The clinical features of haemophilia B are very similar to those of haemophilia A with a prolongation of activated partial thromboplastin time. This case report describes the dental management of a patient with an uncommon haematological disorder, namely, factor IX deficiency, which remained undiagnosed until the patient had to undergo dentofacial trauma with unexpected severe haemorrhage. Preventive dentistry remains vital to young haemophiliacs. Surgical dental procedures may be performed for haemophiliacs but they must be judiciously coordinated by dental and medical health professionals. PMID:25568261

Perioperative management of trauma patients admitted on clopidogrel (Plavix). A survey of orthopaedic departments across the United Kingdom.

Clopidogrel (Plavix) is an anti-platelet drug recommended as lifelong treatment by NICE for all patients following stroke, MI, and peripheral vascular disease. It is also indicated for short-term use following cardiac stent insertion. It irreversibly inhibits platelets for up to 7 days. Current recommendations are to stop treatment 7 days before elective surgery. Current evidence shows that delay to surgery more than 4 days in patients with hip fractures increases postoperative mortality. To determine current practice of orthopaedic surgeons in their management of patients taking clopidogrel admitted following a hip fracture to trauma units in the UK with respect to its peri-operative withdrawal and subsequent timing of surgery. To perform a review of the available literature and produce a suggested protocol for the peri-operative management of this rapidly increasing cohort of patients. National postal survey. Orthopaedic consultants representing each unit receiving trauma patients in the United Kingdom. There was a 57% response rate (139/244 UK trauma units). 41% (56) stop clopidogrel and operate immediately, 11% (15) stop clopidogrel for between 5 and 10 days pre-operatively, 10% (14) stop clopidogrel for 10 days preoperatively, 19% (26) continue clopidogrel and operate immediately, 19% (26) have another protocol. 15% (20) have written departmental guidelines. 2%(3) quoted published evidence for their practice. This study demonstrates that there are a wide variety of practices, largely based on anecdotal evidence. Most units (85%) have no formal guidelines. There is evidence in the cardiac literature of increased intra-operative bleeding in patients operated on while taking clopidogrel. There is likely to be an exponential rise in such patients presenting to trauma units and further research is required to guide best practice. Following review of the literature we propose an interim protocol for the withdrawal and resumption of clopidogrel peri-operatively in patients with hip fractures.

Solid organ (liver, spleen and kidney) haemorrhage is often life threatening and can be difficult to stop in critically ill patients. Traditional techniques for arresting this ongoing bleeding include coagulation by high voltage cautery (Bovie), topical haemostatic application, and the delivery of ignited argon gas. The goal of this study was to evaluate the efficacy of a new energy device for arresting persistent solid organ haemorrhage. A novel instrument utilizing bipolar radiofrequency (RF) energy which acts to ignite/boil dripping saline from a simple hand piece was employed to arrest ongoing bleeding from solid organ injuries at 2 high volume, level 1 trauma centres. This instrument is extrapolated from experience within elective hepatic resections. Standard statistics were employed (p<0.05=significant). From January 2013 to January 2015, 36 severely injured patients (mean injury severity score=31; blunt mechanisms=32/36 (89%)) underwent use of this new saline/RF energy instrument to arrest ongoing haemorrhage from the liver (29), spleen (5) and kidney (2). Of these patients, 25 received instrument use during an initial laparotomy, while 11 patients underwent use following removal of sponges during a return laparotomy after an initial damage control procedure. Success in arresting ongoing haemorrhage was 97% (35/36) in these highly selected cases. The surgeons reported an 'ease of use' score of 4.9 out of 5. No postoperative complications (including delayed haemorrhage) were noted as a direct result of the energy instrument. This simple saline/RF energy instrument has the potential to arrest ongoing solid organ surface/capsular bleeding, as well as moderate haemorrhage associated with deep lacerations.

A postauthorization safety study was performed between 2009 and 2012 to describe the use of Clottafact ® in acquired fibrinogen deficiency in real-life medical practice in France. One hundred and fifty patients were planned for 28 days of prospective follow-up after infusion. The analysis of this observational study was descriptive and performed according to the type of treatment (curative or preventive) and the origin of the bleed. One hundred and fifty-six patients (16-87 years) were included in 13 centres and treated in five different medical bleeding situations: postpartum (59), other gynaecological/obstetrical (6), trauma (34), liver (13), cardiovascular (23) and other various bleeding situations (21). The mean follow-up time was 18·9 ± 12·3 days. Two patients presented adverse drug reactions: one a pulmonary embolism and the other a four-site venous thromboembolic episode. All were serious with a dubious causal relationship with the study treatment. Efficacy data were collected as a secondary objective. In 150 patients receiving curative treatment, 117 of 159 infusions (73·6%) were considered as successful by the investigators, 35 as moderate (22%) and seven as no response (4·4%). The Clottafact ® safety profile observed during the study matched the known profile of fibrinogen during use. © 2017 International Society of Blood Transfusion.

Up to 25% of severely injured patients develop trauma-induced coagulopathy. To study interventions for this vulnerable population for whom consent cannot be obtained easily, the Food and Drug Administration issued regulations for emergency research with an exception from informed consent (ER-EIC). We describe the community consultation and public disclosure (CC/PD) process in preparation for an ER-EIC study, namely the Control Of Major Bleeding After Trauma (COMBAT) study. The CC/PD was guided by the four bioethical principles. We used a multimedia approach, including one-way communications (newspaper ads, brochures, television, radio, and web) and two-way communications (interactive in-person presentations at community meetings, printed and online feedback forms) to reach the trials catchment area (Denver County's population: 643,000 and the Denver larger metro area where commuters reside: 2.9 million). Particular attention was given to special-interests groups (eg, Jehovah Witnesses, homeless) and to Spanish-speaking communities (brochures and presentations in Spanish). Opt-out materials were available during on-site presentations or via the COMBAT study website. A total of 227 community organizations were contacted. Brochures were distributed to 11 medical clinics and 3 homeless shelters. The multimedia campaign had the potential to reach an estimated audience of 1.5 million individuals in large metro Denver area, the majority via one-way communication and 1900 in two-way communications. This resource intensive process cost more than $84,000. The CC/PD process is resource-intensive, costly, and complex. Although the multimedia CC/PD reached a large audience, the effectiveness of this process remains elusive. The templates can be helpful to similar ER-EIC studies. Copyright © 2015 Elsevier Inc.

A 75-year-old woman was involved in a traffic accident and suffered retrograde type A aortic dissection, multiple rib fractures, and grade II hepatic injury accompanied by intraperitoneal bleeding. We performed total arch replacement using an open stent graft with cardiopulmonary bypass and circulatory arrest. This procedure requires anticoagulation and hypothermia, which are principally contraindicated in severe trauma patients. However, this situation was resolved by managing the patient non-operatively for 7 days, confirming the stabilization of other injured organs, and then performing the surgery. She required prolonged postoperative rehabilitation; however, she recovered steadily.

Tissue vibration pulsatility for arterial bleeding detection using Doppler ultrasound.

Xie, Zhiyong; Kim, Eung-Hun; Kim, Yongmin

2009-01-01

Trauma is the number one cause of death among Americans between 1 and 44 years old, and exsanguination due to internal bleeding resulting from arterial injuries is a major factor in trauma deaths. We have evaluated the feasibility of using tissue vibration pulsatility in arterial bleeding detection. Eight femoral arteries from four juvenile pigs were punctured transcutaneously with a 6 or 9-French catheter. Also, 11 silicone vessels wrapped with turkey breast were placed in a pulsatile flow phantom and penetrated with an 18-gauge needle. The tissue vibration pulsatility was derived as a ratio of the maximum spectral energy from 200 to 2500 Hz of tissue vibration in systole over a baseline value in diastole. Then, the tissue vibration pulsatility index (TVPI) was defined as the maximum tissue vibration pulsatility value for each experimental condition. Both in vitro and in vivo results showed that the TVPI from injured vessels is significantly higher (p<0.005) than that of intact vessels. In addition, we constructed the 2D map of tissue vibration pulsatility during in vitro studies and found that it could be used for spatial localization of the puncture site. Our preliminary results indicate that the tissue vibration pulsatility may be useful for detecting arterial bleeding and localizing the bleeding site.

Triage systems are used in emergency medical services to systematically prioritize prehospital resources according to individual patient conditions. Previous studies have shown cases of preventable deaths in emergency medical services even when triage systems are used, indicating a potential undertriage among some conditions. The aim of this study was to investigate the triage level among patients diagnosed with perforated peptic ulcer (PPU) or peptic ulcer bleeding (PUB). In a three-year period in Central Denmark Region, all patients hospitalized within 24 h after a 1-1-2 emergency call and who subsequently received either a PPU or a PUB (hereinafter combined and referred to as PPU/PUB) or a First Hour Quintet (FHQ: respiratory failure, stroke, trauma, cardiac chest pain, and cardiac arrest) diagnosis were investigated. A modified Poisson regression was used to estimate the relative risk of receiving the highest and lowest prehospital response level. Also, a linear regression analysis was used to estimate the relative risk of 30-day mortality. Of 8658 evaluated patients, 263 were diagnosed with PPU/PUB. After adjusting for relevant confounding variables, patients diagnosed with PPU/PUB were less likely to receive ambulance transportation compared to patients diagnosed with stroke, RR = 1.41 (CI: 1.28-1.56); trauma, RR = 1.28 (CI: 1.15-1.42); cardiac chest pain, RR = 1.47 (CI: 1.33-1.62); and cardiac arrest, RR = 1.44 (CI: 1.31-1.42). Among patients diagnosed with PPU/PUB, 6.5% (CI: 3.3-9.7) did not receive ambulance transportation. The proportion of patients not receiving ambulance transportation was higher among patients diagnosed with PPU/PUB compared to patients diagnosed with an FHQ diagnosis. The 30-day mortality rate among patients diagnosed with PPU/PUB was 7.8% (CI: 4.2-11.1). This was lower than the 30-day mortality rate among patients diagnosed with respiratory failure (P = 0.010), stroke (P = 0.001), and cardiac arrest (P < 0.001), but comparable to the 30-day mortality among patients diagnosed with cardiac chest pain (P = 0.080) and trauma (P = 0.281). Among patients calling 1-1-2, fewer patients diagnosed with PPU/PUB received ambulance transportation than patients diagnosed with FHQ diagnoses, despite a high mortality among patients diagnosed with PPU/PUB.

Effective treatment of trauma-induced coagulopathy is important; however, the optimal therapy is still not known. We aimed to compare the efficacy of first-line therapy using fresh frozen plasma (FFP) or coagulation factor concentrates (CFC) for the reversal of trauma-induced coagulopathy, the arising transfusion requirements, and consequently the development of multiple organ failure. This single-centre, parallel-group, open-label, randomised trial was done at the Level 1 Trauma Center in Innsbruck Medical University Hospital (Innsbruck, Austria). Patients with trauma aged 18-80 years, with an Injury Severity Score (ISS) greater than 15, bleeding signs, and plasmatic coagulopathy identified by abnormal fibrin polymerisation or prolonged coagulation time using rotational thromboelastometry (ROTEM) were eligible. Patients with injuries that were judged incompatible with survival, cardiopulmonary resuscitation on the scene, isolated brain injury, burn injury, avalanche injury, or prehospital coagulation therapy other than tranexamic acid were excluded. We used a computer-generated randomisation list, stratification for brain injury and ISS, and closed opaque envelopes to randomly allocate patients to treatment with FFP (15 mL/kg of bodyweight) or CFC (primarily fibrinogen concentrate [50 mg/kg of bodyweight]). Bleeding management began immediately after randomisation and continued until 24 h after admission to the intensive care unit. The primary clinical endpoint was multiple organ failure in the modified intention-to-treat population (excluding patients who discontinued treatment). Reversal of coagulopathy and need for massive transfusions were important secondary efficacy endpoints that were the reason for deciding the continuation or termination of the trial. This trial is registered with ClinicalTrials.gov, number NCT01545635. Between March 3, 2012, and Feb 20, 2016, 100 out of 292 screened patients were included and randomly allocated to FFP (n=48) and CFC (n=52). Six patients (four in the FFP group and two in the CFC group) discontinued treatment because of overlooked exclusion criteria or a major protocol deviation with loss of follow-up. 44 patients in the FFP group and 50 patients in the CFC group were included in the final interim analysis. The study was terminated early for futility and safety reasons because of the high proportion of patients in the FFP group who required rescue therapy compared with those in the CFC group (23 [52%] in the FFP group vs two [4%] in the CFC group; odds ratio [OR] 25·34 [95% CI 5·47-240·03], p<0·0001) and increased needed for massive transfusion (13 [30%] in the FFP group vs six [12%] in the CFC group; OR 3·04 [0·95-10·87], p=0·042) in the FFP group. Multiple organ failure occurred in 29 (66%) patients in the FFP group and in 25 (50%) patients in the CFC group (OR 1·92 [95% CI 0·78-4·86], p=0·15). Our results underline the importance of early and effective fibrinogen supplementation for severe clotting failure in multiple trauma. The available sample size in our study appears sufficient to make some conclusions that first-line CFC is superior to FFP. None. Copyright © 2017 Elsevier Ltd. All rights reserved.

We present a patient with sudden onset progressive shortness of breath and no history of trauma, who rapidly became haemodynamically compromised with a pneumothorax and pleural effusion seen on chest radiograph. He was treated for spontaneous tension pneumothorax but this was soon revealed to be a tension haemopneumothorax. He underwent urgent thoracotomy after persistent bleeding to explore an apical vascular abnormality seen on CT scanning. To our knowledge this is the first such case reported.Aetiology and current approach to spontaneous haemothorax are discussed briefly.

Uncontrolled bleeding is a major cause for early death in both military and civilian trauma. The process of massive bleeding which begins as "surgical bleed" from injured vessels may rapidly evolve into a complex coagulopathy that can be detected early, sometimes within minutes of injury. The magnitude of coagulopathy is directly related to the severity of the injury and its presence is also an independent predictor of early mortality. Therefore, an early "hemostatic resuscitation" is now the "state of the art" in trauma management. Combined mechanisms contribute to the complex coagulopathy as described herein: excessive consumption of coagulation factors and platelets, dilutional coagulopathy due to administration of large volumes of fluids, especially high molecular solutions such as Hydroxyethyl starch (HES); the use of multiple red blood cells (RBC) transfusion without sufficient fresh frozen plasma (FFP) and platelets; acidosis that markedly attenuates thrombin generation and platelets function; hypothermia that slows down enzymatic reactions and platelets function and hyperfibrinolysis which accelerates the degradation of fibrin and might cause platelet dysfunction. An important breakthrough was the understanding that abnormal coagulation tests early in the process of trauma are not the consequences of disseminated intravascular coagulation (DIC). Supported by these new data, an aggressive approach to hemostatic resuscitation was developed which is based on the following principles: permissive hypotension to avoid "dilutional" coagulopathy, awareness of the prevention of hypothermia and acidosis and the use of hemostatic agents such as rFVIIa, fibrinogen concentrate and tranexamic acid early in the course of trauma. Importantly, the common practice of blood component therapy was revised and it is recommended that RBC, FFP and platelets will be transfused early and preferably in 1:1:1 ratio.

This audit examines our total experience with penetrating thoracic trauma. It reviews all the patients who were brought alive to our surgical service and all who were taken directly to the mortuary. The group of patients who underwent emergency operation for penetrating thoracic trauma is examined in detail. A prospective trauma registry is maintained by the Pietermaritzburg Metropolitan Complex. This database was retrospectively interrogated for all patients requiring an emergency thoracic operation for penetrating injury from July 2006 till July 2009. A retrospective review of mortuary data for the same period was undertaken to identify patients with penetrating thoracic trauma who had been taken to the forensic mortuary. Over the 3-year period July 2006 to July 2009, a total of 1186 patients, 77 of whom were female, were admitted to the surgical services in Pietermaritzburg with penetrating thoracic trauma. There were 124 gunshot wounds and 1062 stab wounds. A total of 108 (9%) patients required emergency operation during the period under review. The mechanism of trauma in the operative group was stab wounds (n = 102), gunshot wound (n = 4), stab with compass (n = 1), and impalement by falling on an arrow (n = 1). Over the same period 676 persons with penetrating thoracic trauma were taken to the mortuary. There were 135 (20%) gunshot wounds of the chest in the mortuary cohort. The overall mortality for penetrating thoracic trauma was 541 (33%) of 1603 for stab wounds and 135 (52%) of 259 for gunshot wounds of the chest. Among the 541 subjects with stab wounds from the mortuary cohort, there were 206 (38%) with cardiac injuries. In the emergency operation group there were 11 (10%) deaths. In 76 patients a cardiac injury was identified. The other injuries identified were lung parenchyma bleeding (n = 12) intercostal vessels (n = 10), great vessels of the chest (n = 6), internal thoracic vessel (n = 2), and pericardial injury with no myocardial injury (n = 2). Most patients reached the hospital within 60 minutes of sustaining their injury. A subset of 12 patients had much longer delays of 12 to 24 hours. Surgical access was via median sternotomy in 56 patients and lateral thoracotomy in 52. The overall mortality for penetrating cardiac trauma in our series was 217 (76%) of 282. Penetrating thoracic trauma has a high mortality rate of 30% for subjects with stab wounds and 52% for those with gunshot wounds. Less than a quarter of patients with a penetrating cardiac injury reach the hospital alive. Of those who do and who are operated on, about 90 percent will survive. Other injuries necessitating emergency operation are lung parenchyma, intercostal vessels and internal thoracic vessels, and great vessels of the thorax. Gunshot wounds of the thorax remain more lethal than stab wounds. Copyright © 2011 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

When retained hemothorax occurs, video-assisted thoracoscopy or thoracotomy is performed, but recently, tissue plasminogen activator (tPA) has been used. This study evaluated intrapleural tPA use for retained traumatic hemothoraces. A retrospective review was conducted of trauma patients treated with intrapleural tPA for retained hemothorax. Data included demographics, past medical and surgical histories, injury details, treatment details, and outcomes. Seven patients (median age = 47 years, male = 6, blunt trauma = 6) met study criteria. All patients received a chest tube. Six patients later received computed tomography-guided drains for tPA infusion. Number of tPA treatments per patient varied from 1 to 5. Median total tPA dosage was 24 mg. Median time from injury to chest tube placement was 11 days and from chest tube placement to first tPA treatment was 4 days. No patients required a video-assisted thoracoscopy; however, 1 patient required thoracotomy. There were no deaths or bleeding complications attributed to intrapleural tPA. Although future studies are needed to identify optimum treatment guidelines, intrapleural tPA appears to be a safe and efficacious treatment option. Copyright © 2014 Elsevier Inc.

Thromboprophylaxis with rivaroxaban has proved effective and safe in patients undergoing hip and knee replacement surgery. As it is unclear whether it is also effective and safe in fracture patients, the aim of the present study was to evaluate the efficacy and safety of rivaroxaban in patients with lower limb fractures. We performed a retrospective cohort study of 2,050 consecutive patients treated for lower limb fractures at our trauma center, comparing rates of venous thromboembolism (VTE), bleeding and surgical complications, and the length of hospital stay for 608 patients who received rivaroxaban and 717 who received a low-molecular-weight heparin (LMWH). Rates of symptomatic VTE were 4.9 and 8.6% in the rivaroxaban and LMWH groups, respectively (p = 0.008), and distal VTE rates were 1.8 and 5.7%, respectively (p = 0.036). The incidence of major bleeding events in the rivaroxaban group was also lower than in the LMWH group (0.2 vs 0.6%), but the difference between the groups was not statistically significant. The mean length of hospital stay was significantly shorter in the rivaroxaban group (12.2 vs 13.1 days, respectively; p = 0.016). This retrospective cohort study is the first report documenting the efficacy and safety of rivaroxaban in patients with lower extremity fractures. In comparison with LMWH, rivaroxaban reduced the incidence of VTE by 45% without increasing the risk of bleeding. However, prospective, randomized controlled trials comparing rivaroxaban and LMWH are needed to confirm our findings.

Hemorrhage after blunt trauma is a major contributor to death after trauma. In the abdomen, an injured spleen is the most frequent cause of major bleeding. Splenectomy is historically the treatment of choice. In 2007, non-operative management (NOM) with splenic artery embolization (SAE) was introduced in our institution. The indication for SAE is hemodynamically stable patients with extravasation of contrast, or grade 3-5 spleen injury according to the Abbreviated Organ Injury Scale 2005, Update 2008. We wanted to examine if the introduction of SAE increased the rate of salvaged spleens in our trauma center. All patients discharged with the diagnosis of splenic injury in the period 01.01.2000 - 31.12.2013 from the University Hospital of North Norway Tromsø were included in the study. Patients admitted for rehabilitation purposes or with an iatrogenic injury were excluded. A total of 109 patients were included in the study. In the period 2000-7, 20 of 52 patients were splenectomized. During 2007-13, there were 6 splenectomies and 24 SAE among 57 patients. The reduction in splenectomies is significant (p < 0.001). There is an increase in the rate of treated patients (splenectomy and SAE) from 38 to 53 % in the two time periods, but not significantly (p = 0.65). The rate of salvaged spleens has increased after the introduction of SAE in our center. The study is registered at www.clinicaltrials.gov with the identification number NCT01965548.

Brain micro-bleeds (BMBs) are used as surrogate markers for detecting diffuse axonal injury in traumatic brain injury (TBI) patients. The location and number of BMBs have been shown to influence the long-term outcome of TBI. To further study the importance of BMBs for prognosis, accurate localization and quantification are required. The task of annotating BMBs is laborious, complex and prone to error, resulting in a high inter- and intra-reader variability. In this paper we propose a computer-aided detection (CAD) system to automatically detect BMBs in MRI scans of moderate to severe neuro-trauma patients. Our method consists of four steps. Step one: preprocessing of the data. Both susceptibility (SWI) and T1 weighted MRI scans are used. The images are co-registered, a brain-mask is generated, the bias field is corrected, and the image intensities are normalized. Step two: initial candidates for BMBs are selected as local minima in the processed SWI scans. Step three: feature extraction. BMBs appear as round or ovoid signal hypo-intensities on SWI. Twelve features are computed to capture these properties of a BMB. Step four: Classification. To identify BMBs from the set of local minima using their features, different classifiers are trained on a database of 33 expert annotated scans and 18 healthy subjects with no BMBs. Our system uses a leave-one-out strategy to analyze its performance. With a sensitivity of 90% and 1.3 false positives per BMB, our CAD system shows superior results compared to state-of-the-art BMB detection algorithms (developed for non-trauma patients).

Significant Traumatic Intracranial Hemorrhage in the Setting of Massive Bee Venom-Induced Coagulopathy: A Case Report.

PubMed

Stack, Kelsey; Pryor, Lindsey

2016-09-01

Bees and wasps of the Hymenoptera order are encountered on a daily basis throughout the world. Some encounters prove harmless, while others can have significant morbidity and mortality. Hymenoptera venom is thought to contain an enzyme that can cleave phospholipids and cause significant coagulation abnormalities. This toxin and others can lead to reactions ranging from local inflammation to anaphylaxis. We report a single case of a previously healthy man who presented to the emergency department with altered mental status and anaphylaxis after a massive honeybee envenomation that caused a fall from standing resulting in significant head injury. He was found to have significant coagulopathy and subdural bleeding that progressed to near brain herniation requiring emergent decompression. Trauma can easily occur to individuals escaping swarms of hymenoptera. Closer attention must be paid to potential bleeding sources in these patients and in patients with massive bee envenomation.

Chronic expanding hematoma in the retroperitoneal space: a case report

PubMed Central

2013-01-01

Background Chronic expanding hematoma is a rare condition that develops after surgery, trauma, or injury. It can also develop at any location in the body in the absence of trauma. Clinical findings and various diagnostic imaging modalities can aid in the differential diagnosis of this condition. In general, hematomas are naturally reabsorbed and rarely cause serious problems. However, hematomas that develop slowly without a history of trauma, surgery, or bleeding disorders could be difficult to differentiate from soft tissue neoplasms. In the present case, we describe a patient, without any history or physical evidence of trauma, who exhibited a large chronic expanding hematoma in the retroperitoneal space that resulted in hydronephrosis because of the pressure exerted on the left ureter. Case presentation A 69-year-old man presented to our hospital with a swollen lesion in the left flank. A mass, 19 cm in diameter, was detected in the retroperitoneal space by computed tomography. We suspected the presence of a chronic expanding hematoma, soft tissue tumor, or left renal artery aneurysm. Surgical treatment was performed. However, postoperative histopathological examination indicated that the mass was a nonmalignant chronic expanding hematoma. No recurrence was observed during a 2-year follow-up period. Conclusion In patients without a history of trauma who present slowly growing masses, the differential diagnosis should include chronic expanding hematoma in addition to cysts and soft tissue tumors. Moreover, the use of magnetic resonance imaging and computed tomography is essential to differentiate between chronic expanding hematoma and soft tissue tumors. PMID:24237992

The focused abdominal sonography for trauma (FAST) examination has been reported to be unreliable in pelvic fracture patients. Additionally, given the advent of new therapeutic interventions, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), rapid identification of intra-abdominal hemorrhage compared with Zone III hemorrhage may guide different therapeutic strategies. We hypothesized that FAST is reliable for detecting clinically significant intra-abdominal hemorrhage in the face of complex pelvic fractures. Our pelvic fracture database of all hemodynamically unstable patients requiring intervention from January 1, 2005, to July 1, 2015, was reviewed. The FAST examination was compared with operative and computed tomography (CT) scan findings. Confirmatory evaluation for FAST(-) patients was considered positive if therapeutic intervention was required. During the study period, 81 patients in refractory shock with FAST imaging in our emergency department (ED) underwent pelvic packing. Mean age was 45 ± 2 years and Injury Severity Score was 50 ± 1.5. The FAST examination was negative in 53 patients; 52 patients did not require operative intervention for abdominal bleeding while one patient required splenectomy. The FAST examination was positive in 28 patients; 26 had findings confirmed by CT or laparotomy while two patients did not have intra-abdominal hemorrhage on further evaluation. The sensitivity and specificity for FAST in this population was 96% and 96%, respectively, positive predictive value was 93%, and negative predictive value was 98%. The false-negative and -positive rates for FAST were 2% and 7%. Focused abdominal sonography for trauma examination reliably identifies clinically significant hemoperitoneum in life-threatening, pelvic fracture related hemorrhage. The incidence of a false-negative FAST in this unstable pelvic fracture population was 2%. FAST results may be used when determining the role of REBOA in these multisystem trauma patients and requires further study. REBOA placement should be considered in hemodynamically unstable pelvic fracture patients who are FAST(-), while laparotomy should be used in FAST(+) patients. Therapeutic, level IV.

Nonoperative management (NOM) is standard of care for most pediatric blunt liver and spleen injuries (BLSI); only 5% of patients fail NOM in retrospective reports. No prospective studies examine failure of NOM of BLSI in children. The aim of this study was to determine the frequency and clinical characteristics of failure of NOM in pediatric BLSI patients. A prospective observational study was conducted on patients 18 years or younger presenting to any of 10 Level I pediatric trauma centers April 2013 and January 2016 with BLSI on computed tomography. Management of BLSI was based on the Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium pediatric guideline. Failure of NOM was defined as needing laparoscopy or laparotomy. A total of 1008 patients met inclusion; 499 (50%) had liver injury, 410 (41%) spleen injury, and 99 (10%) had both. Most patients were male (n = 624; 62%) with a median age of 10.3 years (interquartile range, 5.9, 14.2). A total of 69 (7%) underwent laparotomy or laparoscopy, but only 34 (3%) underwent surgery for spleen or liver bleeding. Other (nonexclusive) operations were for 21 intestinal injuries; 15 hematoma evacuations, washouts, or drain placements; 9 pancreatic injuries; 5 mesenteric injuries; 3 diaphragm injuries; and 2 bladder injuries. Patients who failed were more likely to receive blood (52 of 69 vs. 162 of 939; p < 0.001) and median time from injury to first blood transfusion was 2.3 hours for those who failed versus 5.9 hours for those who did not (p = 0.002). Overall mortality rate was 24% (8 of 34) in those who failed NOM due to bleeding. NOM fails in 7% of children with BLSI, but only 3% of patients failed for bleeding due to liver or spleen injury. For children failing NOM due to bleeding, the mortality was 24%. Therapeutic study, level II.

Innominate artery (IA) traumatic injuries are rare but life-threatening, with high mortality and morbidity. Open surgical repair is the treatment of choice but is technically demanding. We describe a case of blunt trauma to the IA with ongoing bleeding, treated successfully by combined (hybrid) endovascular and open surgery. The case demonstrates the immediate usage of modern endovascular and surgical tools as part of endovascular and hybrid trauma management.

This report looks at the group of patients who required a laparotomy for blunt torso trauma at a busy metropolitan trauma service in South Africa. Methods. A prospective trauma registry is maintained by the surgical services of the Pietermaritzburg metropolitan complex. This registry is interrogated retrospectively. All patients who required admission for blunt torso trauma over the period September 2006 - September 2007 were included for review. Proformas documenting mechanism of injury, age, vital signs, blood gas, delay in presentation, length of hospital stay, intensive care unit stay and operative details were completed. Results. A total of 926 patients were treated for blunt trauma by the Pietermaritzburg metropolitan services during the period under consideration. A cohort of 65 (8%) required a laparotomy for blunt trauma during this period. There were 17 females in this group. The mechanisms of injury were motor vehicle accident (MVA) (27), pedestrian vehicle accident (PVA) (21), assault (5), fall from a height (3), bicycle accident (6), quad bike accident (1) and tractor-related accident (2). The following isolated injuries were discovered at laparotomy: liver (9), spleen (5), diaphragm (1), duodenum (2), small bowel (8), mesentery (8) bladder (10), gallbladder (1), stomach (2), colon/rectum (2) and retrohepatic vena cava (1). The following combined injuries were discovered: liver and diaphragm (2), spleen and pancreas (1), spleen and liver (2), spleen, aorta and diaphragm (1), spleen and bladder (1) and small bowel and bladder (2). Eighteen patients in the series (26%) required relaparotomy. In 10 patients temporary abdominal containment was needed. The mortality rate was 26% (18 patients). There were 6 deaths from massive bleeding, all within 6 hours of operation, and 3 deaths from renal failure; the remaining 9 patients died of multiple organ failure. There were 8 negative laparotomies (7%). In the negative laparotomy group false-positive computed tomography (CT) scan findings were a problem in 3 cases, in 1 case hypotension and a fractured pelvis on admission prompted laparotomy, and in the other cases clinical findings prompted laparotomy. All patients who underwent negative laparotomy survived. There were 10 pelvic fractures, 5 lower limb fractures, 2 spinal injuries, 4 femur fractures and 2 upper limb fractures. CT scans were done in 25 patients. In 20 patients the systolic blood pressure on presentation was <90 mmHg and in 41 the pulse rate was >110 beats/min. In 16 patients there was a base excess of <-4 on presentation. Conclusion. Laparotomy is needed in less than 10% of patients who sustain blunt abdominal trauma. Solid visceral injury requiring laparotomy presents with haemodynamic instability. Hollow visceral injury has a more insidious presentation and is associated with a delay in diagnosis. CT scan is the most widely used investigation in blunt abdominal trauma. It is both sensitive and specific for solid visceral injury, but its accuracy for the diagnosis of hollow visceral injury is less well defined. Clinical suspicion must be high, and hollow visceral injury needs to be actively excluded.

Compression dressing has been assumed effective, but never formally examined in the field. A prospective interventional trial examined efficacy and feasibility of an elastic adhesive dressing compression device in the arena of the traumatic incident. The primary variable examined was the bleeding rate from wounds compared before and after dressing. Sixty-two consecutive bleeding wounds resulting from penetrating trauma were treated. Bleeding intensity was profuse in 58%, moderate 23%, and mild in 19%. Full control of bleeding was achieved in 87%, a significantly diminished rate in 11%, and, in 1 case, the technique had no influence on the bleeding rate. The Wilcoxon test for variables comparing bleeding rates before and after the procedure obtained significant difference (Z = -6.9, p < 0.01). No significant complications were observed. Caregivers were highly satisfied in 90% of cases. Elastic adhesive dressing was observed as an effective and reliable technique, demonstrating a high rate of success without complications.

Rectus sheath hematoma (RSH) is a rare clinical entity. It can be mistaken for other intra-abdominal disorders, which can result in diagnostic and therapeutic difficulties. This study was undertaken to analyze the clinical presentation, diagnostic modalities, and management of patients affected with RSH. Between January 2008 and June 2011, eight patients (5 men and 3 women with a mean age of 53 years) with RSH were evaluated according to demographic characteristics, clinical and radiological findings, and methods of treatment. Six patients developed RSH after anticoagulant therapy; one after local trauma, and one after laparoscopic intervention. Six patients were treated nonsurgically; one patient underwent embolization of the inferior epigastric artery and one underwent ligation of the bleeding vessel. The average hospital stay was 6 days. There were no mortality or thromboembolic complications. RSH is a rare nonneoplastic entity that is usually associated with abdominal trauma and/or anticoagulant therapy. The gold standard for diagnosis is computed tomography, and ultrasonography can be used in follow-up. The treatment of choice is nonsurgical therapy because RSH is a self-limited condition. Surgical intervention should be reserved for cases with hemodynamic instability. Copyright © 2013. Published by Elsevier B.V.

Estimation of plasma fibrinogen levels based on hemoglobin, base excess and Injury Severity Score upon emergency room admission

PubMed Central

2013-01-01

Introduction Fibrinogen plays a key role in hemostasis and is the first coagulation factor to reach critical levels in massively bleeding trauma patients. Consequently, rapid estimation of plasma fibrinogen (FIB) is essential upon emergency room (ER) admission, but is not part of routine coagulation monitoring in many centers. We investigated the predictive ability of the laboratory parameters hemoglobin (Hb) and base excess (BE) upon admission, as well as the Injury Severity Score (ISS), to estimate FIB in major trauma patients. Methods In this retrospective study, major trauma patients (ISS ≥16) with documented FIB analysis upon ER admission were eligible for inclusion. FIB was correlated with Hb, BE and ISS, alone and in combination, using regression analysis. Results A total of 675 patients were enrolled (median ISS 27). FIB upon admission correlated strongly with Hb, BE and ISS. Multiple regression analysis showed that Hb and BE together predicted FIB (adjusted R2 = 0.46; loge(FIB) = 3.567 + 0.223.Hb - 0.007.Hb2 + 0.044.BE), and predictive strength increased when ISS was included (adjusted R2 = 0.51; loge(FIB) = 4.188 + 0.243.Hb - 0.008.Hb2 + 0.036.BE - 0.031.ISS + 0.0003.ISS2). Of all major trauma patients admitted with Hb <12 g/dL, 74% had low (<200 mg/dL) FIB and 54% had critical (<150 mg/dL) FIB. Of patients admitted with Hb <10 g/dL, 89% had low FIB and 73% had critical FIB. These values increased to 93% and 89%, respectively, among patients with an admission Hb <8 g/dL. Sixty-six percent of patients with only a weakly negative BE (<−2 mmol/L) showed low FIB. Of patients with BE <−6 mmol/L upon admission, 81% had low FIB and 63% had critical FIB. The corresponding values for BE <−10 mmol/L were 89% and 78%, respectively. Conclusions Upon ER admission, FIB of major trauma patients shows strong correlation with rapidly obtainable, routine laboratory parameters such as Hb and BE. These two parameters might provide an insightful and rapid tool to identify major trauma patients at risk of acquired hypofibrinogenemia. Early calculation of ISS could further increase the ability to predict FIB in these patients. We propose that FIB can be estimated during the initial phase of trauma care based on bedside tests.

[Psychogenic purpura with hematuria and sexual pain disorder: a case report].

2010-01-01

Psychogenic purpura (Gardner-Diamond syndrome) is the occurrence and spontaneous recurrence of painful ecchymosis following emotional stress and minor trauma. Although the exact mechanism of this syndrome remains unknown, apart from skin lesions, different types of hemorrhaging have been reported, such as epistaxis, gastrointestinal bleeding, and bleeding from the ear canals and eyes. We report a psychogenic purpura case that presented with hematuria in addition to skin lesions. Based on the psychiatric evaluation she was diagnosed with major depressive disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Additionally, sexual pain disorder accompanied these disorders. With the help of antidepressant and supportive psychotherapy, the patient's ecchymosis and bleeding disappeared. During 8 months of follow-up the symptoms did not return. Vaginismus has not been reported in patients with psychogenic purpura. The presence of vaginismus, which is seen more frequently in eastern cultures and is thought to be related to sociocultural determinants, suggests that some cultural factors may be common to both psychogenic purpura and vaginismus. The aim of this case report was to call attention to a syndrome that is rarely seen and diagnosed, and to discuss its relationship to psychosocial factors. This syndrome should be considered in the differential diagnosis of not only ecchymotic lesions, but also various types of bleeding, including hematuria. Despite the fact that its etiology and treatment are not clearly understood, it should be noted that psychological factors play a role in this disease and therefore, psychopharmacological and psychotherapeutic approaches can be effective.

Recurrent haematomas of the thigh: a case of von Willebrand's disease presenting to a sports clinic

Von Willebrand's disease is a relatively common mild form of haemophilia. It should be suspected in assessing sports injuries when excessive bleeding occurs in response to relatively mild trauma. Those with the disease should remain active but avoid contact sports. They should not take aspirin or non-steroidal anti-inflammatory drugs, which may exacerbate bleeding, and should be given supportive treatment to cover dental extraction, surgery, or significant bleeding episodes.

Severe hepatic trauma: nonoperative management, definitive repair, or damage control surgery?

2011-12-01

Management of severe liver injuries has evolved to include the options for nonoperative management and damage control surgery. The present study analyzes the criteria for choosing between nonoperative management and early surgery, and definitive repair versus damage control strategy during early surgery. In a retrospective analysis of 144 patients with severe (AAST grade III-V) liver injuries (94% blunt trauma), early laparotomy was performed in 50 patients. Initial management was nonoperative in 94 blunt trauma patients with 8 failures. Uni- and multivariate analyses were used to calculate predictor odds ratios (OR) with 95% confidence intervals (CI). Factors associated with early laparotomy in blunt trauma included shock on admission, associated grade IV-V splenic injury, grade IV-V head injury, and grade V liver injury. Only shock was an independent predictor (OR, 26.1; 95% CI, 8.9-77.1; P < 0.001). The presence of a grade IV-V splenic injury predicted damage control strategy (OR infinite; P = 0.021). Failed nonoperative management was associated with grade IV-V splenic injury (OR, 14.00; 95% CI, 1.67-117.55), and shock (OR, 6.82; 95% CI, 1.49-31.29). The hospital mortality rate was 15%; 8 of 21 deaths were liver-related. Shock (OR, 9.3; 95% CI, 2.4-35.8; P = 0.001) and severe head injury (OR, 9.25; 95% CI, 3.0-28.9; P = 0.000) were independent predictors for mortality. In patients with severe liver injury, associated severe splenic injury favors early laparotomy and damage control strategy. Patients who arrive in shock or have an associated severe splenic injury should not be managed nonoperatively. In addition to severe head injury, uncontrollable bleeding from the liver injury is still a major cause of early death.

The aim of this study was to evaluate the impact of a novel trauma workflow, using an interventional radiology (IVR)-computed tomography (CT) system in severe trauma. In August 2011, we installed an IVR-CT system in our trauma resuscitation room. We named it the Hybrid emergency room (ER), as it enabled us to perform all examinations and treatments required for trauma in a single place. This retrospective historical control study conducted in Japan included consecutive severe (injury severity score ≥16) blunt trauma patients. Patients were divided into 2 groups: Conventional (from August 2007 to July 2011) or Hybrid ER (from August 2011 to July 2015). We set the primary endpoint as 28-day mortality. The secondary endpoints included cause of death and time course from arrival to start of CT and surgery. Multivariable logistic regression analysis adjusted for clinically important variables was performed to evaluate the clinical outcomes. We included 696 patients: 360 in the Conventional group and 336 in the Hybrid ER group. The Hybrid ER group was significantly associated with decreased mortality [adjusted odds ratio (OR), 0.50 (95% confidence interval, 95% CI, 0.29-0.85); P = 0.011] and reduced deaths from exsanguination [0.17 (0.06-0.47); P = 0.001]. The time to CT initiation [Conventional 26 (21 to 32) minutes vs Hybrid ER 11 (8 to 16) minutes; P < 0.0001] and emergency procedure [68 (51 to 85) minutes vs 47 (37 to 57) minutes; P < 0.0001] were both shorter in the Hybrid ER group. This novel trauma workflow, comprising immediate CT diagnosis and rapid bleeding control without patient transfer, as realized in the Hybrid ER, may improve mortality in severe trauma.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

Intravenous hemostats: challenges in translation to patients

Excessive bleeding and the resulting complications are a leading killer of young people globally. There are many successful methods to halt bleeding in the extremities, including compression, tourniquets, and dressings. However, current treatments for internal hemorrhage (including from head or truncal injuries), termed non-compressible bleeding, are inadequate. For these non-compressible injuries, blood transfusions are the current treatment standard. However, they must be refrigerated, may potentially transfer disease, and are of limited supply. In addition, time is of the essence for halting hemorrhage, since more than a third of civilian deaths due to hemorrhage from trauma occur before the patient even reaches the hospital. As a result, particles that can cross-link activated platelets through the glycoprotein IIb/IIIa receptor expressed on activated platelets are being investigated as an alternative treatment for non-compressible bleeding. Ideally, these particles would interact specifically with platelets to stabilize the platelet plug. Initial designs used biologically derived microparticles with red blood cell fragment or albumin cores decorated with RGD or fibrinogen, which bind to GPIIb/IIIa. More recently there has been research into the use of fully synthetic nanoparticles with liposomal or polymer cores that crosslink platelets through a targeting peptide bound to the surface. Some of the challenges for the development of these particles include appropriate sizing to prevent blocking the capillaries of the lungs, immune system evasion to prevent strong reactions and increase circulation time, and storage and resuspension so that first responders can easily use the particles. In addition, the effectiveness of the variety of animal bleeding models in predicting outcomes must be examined before test results can be fully understood. Progress has been made in the development of particles to combat hemorrhage, but issues of immune sensitivity and storage must be resolved before these types of particles can be translated for human use.

Background: Severe bleeding as a result of trauma frequently leads to poor outcome by means of direct or delayed mechanisms. Prehospital fluid therapy is still regarded as the main option of primary treatment in many rescue situations. Our study aimed to assess the influence of prehospital fluid replacement on the posttraumatic course of severely injured patients in a retrospective analysis of matched pairs. Materials and Methods: We reviewed data from 35,664 patients recorded in the Trauma Registry of the German Society for Trauma Surgery (DGU). The following patients were selected: patients having an Injury Severity Score >16 points, who were ≥16 years of age, with trauma, excluding those with craniocerebral injuries, who were admitted directly to the participating hospitals from the accident site. All patients had recorded values for replaced volume and blood pressure, hemoglobin concentration, and units of packed red blood cells given. The patients were matched based on similar blood pressure characteristics, age groups, and type of accident to create pairs. Pairs were subdivided into two groups based on the volumes infused prior to hospitalization: group 1: 0-1500 (low), group 2: ≥2000 mL (high) volume. Results: We identified 1351 pairs consistent with the inclusion criteria. Patients in group 2 received significantly more packed red blood cells (group 1: 6.9 units, group 2: 9.2 units; P=0.001), they had a significantly reduced capacity of blood coagulation (prothrombin ratio: group 1: 72%, group 2: 61.4%; P≤0.001), and a lower hemoglobin value on arrival at hospital (group 1: 10.6 mg/dL, group 2: 9.1 mg/dL; P≤0.001). The number of ICU-free days concerning the first 30 days after trauma was significantly higher in group 1 (group 1: 11.5 d, group 2: 10.1 d; P≤0.001). By comparison, the rate of sepsis was significantly lower in the first group (group 1: 13.8%, group 2: 18.6%; P=0.002); the same applies to organ failure (group 1: 36.0%, group 2: 39.2%; P≤0.001). Conclusion: The high amounts of intravenous fluid replacement was related to early traumatic coagulopathy, organ failure, and sepsis rate. PMID:22090739

INTRODUCTION Portable firearms have a relevant medico-legal interest, being a major cause of injury. Bullet entry wounds generally have a particular appearance, including contusion, skin introflection, and simple or excoriated ecchymosis. The skin wound is typically a hole with frayed margins, whose diameter is smaller than that of the bullet. PRESENTATION OF CASE We report the case of a 19-year-old man with ballistic trauma. Examination of the patient's lesions indicated that the bullet had entered from the left mandibular parasymphysis, creating a small hole without the typical bullet wipe and blackening. Subsequently, the bullet seemed to have fractured the left chin region immediately below the lower alveolar process, and it finally stopped in the submandibular area in the suprahyoid region of the neck. DISCUSSION This case is peculiar because the distinctive features of a firearm injury were absent; the lack of bleeding and edema made the case difficult to interpret without additional diagnostic investigations. CONCLUSION Ballistic trauma can manifest in different ways; therefore, internal trauma should be suspected even in the absence of clear external signs. This case report shows how an unusual bullet entry hole can mask quite serious injuries. PMID:22096751

Prophylactic enoxaparin is used to prevent venous thromboembolism (VTE) in surgical and trauma patients. However, VTE remains an important source of morbidity and mortality, potentially exacerbated by antithrombin III or anti-Factor Xa deficiencies and missed enoxaparin doses. Recent data suggest that a difference in reaction time (time to initial fibrin formation) greater than 1 minute between heparinase and standard thrombelastogram (TEG) is associated with a decreased risk of VTE. To evaluate the effectiveness of TEG-adjusted prophylactic enoxaparin dosing among trauma and surgical patients. This randomized clinical trial, conducted from October 2012 to May 2015, compared standard dosing (30 mg twice daily) with TEG-adjusted enoxaparin dosing (35 mg twice daily) for 185 surgical and trauma patients screened for VTE at 3 level I trauma centers in the United States. The incidence of VTE, bleeding complications, anti-Factor Xa deficiency, and antithrombin III deficiency. Of the 185 trial participants, 89 were randomized to the control group (median age, 44.0 years; 55.1% male) and 96 to the intervention group (median age, 48.5 years; 74.0% male). Patients in the intervention group received a higher median enoxaparin dose than control patients (35 mg vs 30 mg twice daily; P < .001). Anti-Factor Xa levels in intervention patients were not higher than levels in control patients until day 6 (0.4 U/mL vs 0.21 U/mL; P < .001). Only 22 patients (11.9%) achieved a difference in reaction time greater than 1 minute, which was similar between the control and intervention groups (10.4% vs 13.5%; P = .68). The time to enoxaparin initiation was similar between the control and intervention groups (median [range] days, 1.0 [0.0-2.0] vs 1.0 [1.0-2.0]; P = .39), and the number of patients who missed at least 1 dose was also similar (43 [48.3%] vs 54 [56.3%]; P = .30). Rates of VTE (6 [6.7%] vs 6 [6.3%]; P > .99) were similar, but the difference in bleeding complications (5 [5.6%] vs 13 [13.5%]; P = .08) was not statistically significant. Antithrombin III and anti-Factor Xa deficiencies and hypercoagulable TEG parameters, including elevated coagulation index (>3), maximum amplitude (>74 mm), and G value (>12.4 dynes/cm2), were prevalent in both groups. Identified risk factors for VTE included older age (61.0 years vs 46.0 years; P = .04), higher body mass index (calculated as weight in kilograms divided by height in meters squared; 30.6 vs 27.1; P = .03), increased Acute Physiology and Chronic Health Evaluation II score (8.5 vs 7.0; P = .03), and increased percentage of missed doses per patient (14.8% vs 2.5%; P = .05). The incidence of VTE was low and similar between groups; however, few patients achieved a difference in reaction time greater than 1 minute. Antithrombin III deficiencies and hypercoagulable TEG parameters were prevalent among patients with VTE. Low VTE incidence may be due to an early time to enoxaparin initiation and an overall healthier and less severely injured study population than previously reported. clinicaltrials.gov Identifier: NCT00990236.

A literature review was conducted to assess the efficacy and safety of dimethyl sulfoxide (DMSO) cryopreserved platelets for potential military use. In vivo DMSO cryopreserved platelet studies published between 1972 and June of 2013 were reviewed. Assessed were the methods of cryopreservation, posttransfusion platelet responses, prevention or control of bleeding, and adverse events. Using the Department of Defense's preferred 6% DMSO cryopreservation method with centrifugation to remove the DMSO plasma before freezing at -65°C and no postthaw wash, mean radiolabeled platelet recoveries in 32 normal subjects were 33% ± 10% (52% ± 12% of the same subject's fresh platelet recoveries), and survivals were 7.5 ± 1.2 days (89% ± 15% of fresh platelet survivals). Using a variety of methods to freeze autologous platelets from 178 normal subjects, mean radiolabeled platelet recoveries were consistently 39% ± 9%, and survivals, 7.4 ± 1.4 days. More than 3000 cryopreserved platelet transfusions were given to 1334 patients. There were 19 hematology/oncology patient studies, and, in 9, mean 1-hour corrected count increments were 11 100 ± 3600 (range, 5700-15 800) after cryopreserved autologous platelet transfusions. In 5 studies, bleeding times improved after transfusion; in 3, there was either no improvement or a variable response. In 4 studies, there was immediate cessation of bleeding after transfusion; in 3 studies, patients being supported only with cryopreserved platelets had no bleeding. In 1 cardiopulmonary bypass study, cryopreserved platelets resulted in significantly less bleeding vs standard platelets. In 3 trauma studies, cryopreserved platelets were hemostatically effective. No significant adverse events were reported in any study. In summary, cryopreserved platelets have platelet recoveries that are about half of fresh platelets, but survivals are only minimally reduced. The platelets appear hemostatically effective and have no significant adverse events. Copyright © 2014 Elsevier Inc. All rights reserved.

Management of bleeding in vascular surgery.

PubMed

Chee, Y E; Liu, S E; Irwin, M G

2016-09-01

Management of acute coagulopathy and blood loss during major vascular procedures poses a significant haemostatic challenge to anaesthetists. The acute coagulopathy is multifactorial in origin with tissue injury and hypotension as the precipitating factors, followed by dilution, hypothermia, acidemia, hyperfibrinolysis and systemic inflammatory response, all acting as a self-perpetuating spiral of events. The problem is confounded by the high prevalence of antithrombotic agent use in these patients and intraoperative heparin administration. Trials specifically examining bleeding management in vascular surgery are lacking, and much of the literature and guidelines are derived from studies on patients with trauma. In general, it is recommended to adopt permissive hypotension with a restrictive fluid strategy, using a combination of crystalloid and colloid solutions up to one litre during the initial resuscitation, after which blood products should be administered. A restrictive transfusion trigger for red cells remains the mainstay of treatment except for the high-risk patients, where the trigger should be individualized. Transfusion of blood components should be initiated by clinical evidence of coagulopathy such as diffuse microvascular bleeding, and then guided by either laboratory or point-of-care coagulation testing. Prophylactic antifibrinolytic use is recommended for all surgery where excessive bleeding is anticipated. Fibrinogen and prothrombin complex concentrates administration are recommended during massive transfusion, whereas rFVIIa should be reserved until all means have failed. While debates over the ideal resuscitative strategy continue, the approach to vascular haemostasis should be scientific, rational, and structured. As far as possible, therapy should be monitored and goal directed. © The Author 2016. Published by Oxford University Press on behalf of the British Journal of Anaesthesia. All rights reserved.

The Role of Intraoperative Cerebral Angiography in Transorbital Intracranial Penetrating Trauma: A Case Report and Literature Review.

Riley, Jonathan P; Boucher, Andrew B; Kim, Denise S; Barrow, Daniel L; Reynolds, Matthew R

2017-01-01

Transorbital intracranial penetrating trauma with a retained intracranial foreign body is a rare event lacking a widely accepted diagnostic and therapeutic algorithm. Intraoperative catheter angiography (IOA) has been advocated by some authorities to rule out cerebrovascular injury before and/or after removal of the object, but no standard of care currently exists. A 19-year-old man was involved in a construction site accident whereby a framing nail penetrated the left globe, traversed the lateral bony orbit, and terminated in the midtemporal lobe. No hematoma or injury to the middle cerebral arteries (MCAs) was apparent on noncontrast head computed tomography (CT) or CT angiography, respectively. The foreign body was removed in the operating room under direct visualization after a frontotemporal craniotomy without incident. No significant venous or arterial bleeding was encountered. All visualized MCA branches appeared intact. Indocyanine green videoangiography performed immediately after object removal showed adequate filling of the MCA branches. Given these uneventful clinical and radiographic findings, IOA was not performed. Postoperative head CT and CT angiography showed no obvious neurovascular injury. On postoperative day 2, the patient was noted to have an expressive aphasia. Cerebral angiography showed absent antegrade filling of the angular artery with some retrograde perfusion. Magnetic resonance imaging confirmed an ischemic infarction in the midtemporal lobe. The patient's expressive aphasia improved to near baseline during his hospitalization and he made an excellent clinical recovery. In transorbital intracranial penetrating trauma with a retained intracranial object, we advocate microsurgical removal of the object under direct visualization followed immediately by IOA. IOA should be strongly considered even in the setting of minimal intraoperative bleeding and normal findings on videoangiography (a course of action that was not followed in the present case). Given that CT angiography and intraoperative videoangiography may miss a potentially treatable traumatic arterial injury, IOA can help determine whether cerebral revascularization may be necessary.

To determine if stable patients with a hemopericardium detected after penetrating chest trauma can be safely managed with pericardial drainage alone. The current international practice is to perform a sternotomy and cardiac repair if a hemopericardium is detected after penetrating chest trauma. The experience in Cape Town, South Africa, on performing a mandatory sternotomy in hemodynamically stable patients was that a sternotomy was unnecessary and the cardiac injury, if present, had sealed. A single-center parallel-group randomized controlled study was completed. All hemodynamically stable patients with a hemopericardium confirmed at subxiphoid pericardial window (SPW), and no active bleeding, were randomized. The primary outcome measure was survival to discharge from hospital. Secondary outcomes were complications and postoperative hospital stay. Fifty-five patients were randomized to sternotomy and 56 to pericardial drainage and wash-out only. Fifty-one of the 55 patients (93%) randomized to sternotomy had either no cardiac injury or a tangential injury. There were only 4 patients with penetrating wounds to the endocardium and all had sealed. There was 1 death postoperatively among the 111 patients (0.9%) and this was in the sternotomy group. The mean intensive care unit (ICU) stay for a sternotomy was 2.04 days (range, 0-25 days) compared with 0.25 days (range, 0-2) for the drainage (P < 0.001). The estimated mean difference highlighted a stay of 1.8 days shorter in the ICU for the drainage group (95% CI: 0.8-2.7). Total hospital stay was significantly shorter in the SPW group (P < 0.001; 95% CI: 1.4-3.3). SPW and drainage is effective and safe in the stable patient with a hemopericardium after penetrating chest trauma, with no increase in mortality and a shorter ICU and hospital stay.

Summary Introduction: Severe Epistaxis is common in patients with head trauma, especially when associated with multiple fractures of the face and skull base. Several methods of controlling bleeding that can be imposed. The anterior nasal tapenade associated with posterior Foley catheter is one of the most widespread, and the universal availability of necessary materials or their apparent ease of execution. Methods: Case report on control of severe epistaxis after severe TBI, with posterior nasal packing by Foley catheter and control tomography showing multiple fractures of the skull base and penetration of the probe into the brain parenchyma. Conclusion: This is a rare but possible complication in the treatment of severe nose bleeds associated with fracture of the skull base. This brief report highlights risks related to the method and suggests some care to prevent complications related through a brief literature review. PMID:25991984

Is viscoelastic coagulation monitoring with ROTEM or TEG validated?

PubMed

Solomon, Cristina; Asmis, Lars M; Spahn, Donat R

2016-10-01

Recent years have seen increasing worldwide interest in the use of viscoelastic coagulation monitoring tests, performed using devices such as ROTEM and TEG. The use of such tests to guide haemostatic therapy may help reduce transfusion of allogeneic blood products in bleeding patients and is supported in European guidelines for managing trauma and severe perioperative bleeding. In addition, viscoelastic tests form the basis of numerous published treatment algorithms. However, some publications have stated that viscoelastic tests are not validated. A specific definition of the term validation is lacking and regulatory requirements of the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) have been fulfilled by ROTEM and TEG assays. Viscoelastic tests have been used in pivotal clinical trials, and they are approved for use in most of the world's countries. Provided that locally approved indications are adhered to, the regulatory framework for clinicians to use viscoelastic tests in routine clinical practice is in place.

Mucormycosis is a rare fungal infection of the mucorales order, which affects mostly immunocompromised patients. The association with emphysematous gastritis is rare and often fatal produced by gas -forming bacteria. We report the case of a trauma patient with type 1 diabetes mellitus, and diabetic ketoacidosis complicated with gastric mucormycosis associated with emphysematous gastritis. A male aged 32 who is involved in a car accident, who suffered head trauma, is admitted to the Intensive Care Unit, presenting diabetic ketoacidosis and upper gastrointestinal bleeding. An endoscopy was performed and an erosive esophagitis Class C, ischemia and gastric necrosis was found. A computed tomography scan showed emphysematous gastritis and gastric necrosis. He underwent total gastrectomy with a histopathology report of gastric mucormycosis. After the surgical procedure the patient died because of sepsis secondary to pulmonary mucormycosis Mucormycosis is a rare fungical disease which infrequently affects the gastrointestinal tract, being the stomach the most affected site. The mortality is high if the diagnosis is not done promptly and appropriate treatment is given. Suspecting its existence is necessary in patients with immunocompromised status to diagnose and provide timely treatment to increase survival, because of its high mortality. Copyright © 2015.

Identification and immediate treatment of life-threatening conditions is fundamental in patients with multiple trauma. In this context, the S3 guidelines on polytrauma and the S1 guidelines on emergency anesthesia provide the scientific background on how to handle these situations. This case report deals with a seriously injured driver involved in a truck accident. The inaccessible patient showed a scalping injury of the facial skeleton with massive bleeding and partially blocked airway but with spontaneous breathing as well as centralized cardiovascular circulation conditions and an initial Glasgow coma scale (GCS) of 8. An attempt was made to stop the massive bleeding by using hemostyptic-coated dressings. In addition, the patient was intubated via video laryngoscopy and received a left and right thoracic drainage as well as two entry points for intraosseous infusion. In modern emergency medical services, treatment based on defined algorithms is recommended and also increasingly established in dealing with critical patients. The guideline-oriented emergency care of patients with polytrauma requires invasive measures, such as intubation and thoracic decompression in the preclinical setting. The foundation for this procedure includes training in theory and practice both of the non-medical and medical rescue service personnel.

Accidental hypothermia, acidosis, and coagulopathy represent the lethal triad in severely injured patients. Therapeutic hypothermia however is commonly used in transplantations, cardiac and neurosurgical surgery, or after cardiac arrest. However, the effects of therapeutic hypothermia on the coagulation system following multiple trauma need to be elucidated. In a porcine model of multiple trauma including blunt chest injury, liver laceration, and hemorrhagic shock followed by fluid resuscitation, the influence of therapeutic hypothermia on coagulation was evaluated. A total of 40 pigs were randomly assigned to sham (only anesthesia) or trauma groups receiving either hypothermia or normothermia. Each group consisted of 10 pigs. Analyzed parameters were cell count (red blood cells, platelets), pH, prothrombin time (PT), fibrinogen concentration, and analysis with ROTEM and Multiplate. Trauma and consecutive fluid resuscitation resulted in impaired coagulation parameters (cell count, pH, PT, fibrinogen, ROTEM, and platelet function). During hypothermia, coagulation parameters measured at 37°C, such as PT, fibrinogen, thrombelastometry measurements, and platelet function, showed no significant differences between normothermic and hypothermic animals in both trauma groups. Additional analyses of thrombelastometry at 34°C during hypothermia showed significant differences for clotting time and clot formation time but not for maximum clot firmness. We were not able to detect macroscopic or petechial bleeding in both trauma groups. Based on the results of the present study we suggest that mild hypothermia can be safely performed after stabilization following major trauma. Mild hypothermia has effects on the coagulation system but does not aggravate trauma-induced coagulopathy in our model. Before hypothermic treatment can be performed in the clinical setting, additional experiments with prolonged and deeper hypothermia to exclude detrimental effects are required.

OBJECTIVES Retained haemothorax and pneumothorax are the most common complications after blunt chest traumas. Lung lacerations derived from fractures of the ribs are usually found in these patients. Video-assisted thoracoscopic surgery (VATS) is usually used as a routine procedure in the treatment of retained pleural collections. The objective of this study was to find out if there is any advantage in adding the procedure for repairing lacerated lungs during VATS. METHODS Patients who were brought to our hospital with blunt chest trauma were enrolled into this prospective cohort study from January 2004 to December 2011. All enrolled patients had rib fractures with type III lung lacerations diagnosed by CT scans. They sustained retained pleural collections and surgical drainage was indicated. On one group, only evacuation procedure by VATS was performed. On the other group, not only evacuations but also repair of lung injuries were performed. Patients with penetrating injury or blunt injury with massive bleeding, that required emergency thoracotomy, were excluded from the study, in addition to those with cardiovascular or oesophageal injuries. RESULTS During the study period, 88 patients who underwent thoracoscopy were enrolled. Among them, 43 patients undergoing the simple thoracoscopic evacuation method were stratified into Group 1. The remaining 45 patients who underwent thoracoscopic evacuation combined with resection of lung lacerations were stratified into Group 2. The rates of post-traumatic infection were higher in Group 1. The durations of chest-tube drainage and ventilator usage were shorter in Group 2, as were the lengths of patient intensive care unit stay and hospital stay. CONCLUSIONS When compared with simple thoracoscopic evacuation methods, repair and resection of the injured lungs combined may result in better clinical outcomes in patients who sustained blunt chest injuries.

The Australian and New Zealand (ANZ) Massive Transfusion (MT) Registry (MTR) has been established to improve the quality of care of patients with critical bleeding (CB) requiring MT (≥ 5 units red blood cells (RBC) over 4 h). The MTR is providing data to: (1) improve the evidence base for transfusion practice by systematically collecting data on transfusion practice and clinical outcomes; (2) monitor variations in practice and provide an opportunity for benchmarking, and feedback on practice/blood product use; (3) inform blood supply planning, inventory management and development of future clinical trials; and (4) measure and enhance translation of evidence into policy and patient blood management guidelines. The MTR commenced in 2011. At each participating site, all eligible patients aged ≥18 years with CB from any clinical context receiving MT are included using a waived consent model. Patient information and clinical coding, transfusion history, and laboratory test results are extracted for each patient's hospital admission at the episode level. Thirty-two hospitals have enrolled and 3566 MT patients have been identified across Australia and New Zealand between 2011 and 2015. The majority of CB contexts are surgical, followed by trauma and gastrointestinal haemorrhage. Validation studies have verified that the definition of MT used in the registry correctly identifies 94 % of CB events, and that the median time of transfusion for the majority of fresh products is the 'product event issue time' from the hospital blood bank plus 20 min. Data linkage between the MTR and mortality databases in Australia and New Zealand will allow comparisons of risk-adjusted mortality estimates across different bleeding contexts, and between countries. Data extracts will be examined to determine if there are differences in patient outcomes according to transfusion practice. The ratios of blood components (e.g. FFP:RBC) used in different types of critical bleeding will also be investigated. The MTR is generating data with the potential to have an impact on management and policy decision-making in CB and MT and provide benchmarking and monitoring tools for immediate application.

The prevalence, type and etiology of dental and soft tissue injuries and relationship between the time of arrival and sustaining soft tissue injury were analyzed in this retrospective study conducted at the Department of Pediatric Dentistry, University Dental Clinic in Zagreb, Croatia, during the 2010-2014 period using documentation on 447 patients (264 male and 183 female) aged 1-16 years with injuries of primary and permanent teeth. The highest prevalence of traumatic dental injury (TDI) was found in the 7-12 age group and maxillary central incisors were most frequently affected (80.9%) in both primary and permanent dentitions. Enamel-dentin fracture without pulp exposure (31.9%) was the most common TDI of dental hard tissue in both dentitions, whereas subluxation (27.3%) was the most common periodontal tissue injury type. The most frequent location, cause and seasonal variation of trauma were at home, falling and spring. Soft tissue injuries were observed in 203 (45.4%) patients. Soft tissue injuries were less likely when fewer teeth were traumatized (p<0.001). Comparison of children with and without soft tissue injuries yielded a statistically significant difference in the time to arrival between primary and permanent teeth (p<0.01). Because soft tissue injuries include bleeding and clinical presentation appears more dramatic, the time elapsed between injury and initial treatment was shorter than in non-bleeding injuries, pointing to the need of education focused on parents and school teachers regarding the importance of immediate therapy for both bleeding and non-bleeding TDIs.

Acute nonvariceal upper gastrointestinal (UGI) hemorrhage is a frequent complication associated with significant morbidity and mortality. The most common cause of UGI bleeding is peptic ulcer disease, but the differential diagnosis is diverse and includes tumors; ischemia; gastritis; arteriovenous malformations, such as Dieulafoy lesions; Mallory-Weiss tears; trauma; and iatrogenic causes. Aggressive treatment with early endoscopic hemostasis is essential for a favorable outcome. However, severe bleeding despite conservative medical treatment or endoscopic intervention occurs in 5-10% of patients, requiring surgery or transcatheter arterial embolization. Surgical intervention is usually an expeditious and gratifying endeavor, but it can be associated with high operativemore » mortality rates. Endovascular management using superselective catheterization of the culprit vessel, < sandwich> occlusion, or blind embolization has emerged as an alternative to emergent operative intervention for high-risk patients and is now considered the first-line therapy for massive UGI bleeding refractory to endoscopic treatment. Indeed, many published studies have confirmed the feasibility of this approach and its high technical and clinical success rates, which range from 69 to 100% and from 63 to 97%, respectively, even if the choice of the best embolic agent among coils, cyanaocrylate glue, gelatin sponge, or calibrated particles remains a matter of debate. However, factors influencing clinical outcome, especially predictors of early rebleeding, are poorly understood, and few studies have addressed this issue. This review of the literature will attempt to define the role of embolotherapy for acute nonvariceal UGI hemorrhage that fails to respond to endoscopic hemostasis and to summarize data on factors predicting angiographic and embolization failure.« less

Penetrating cardiac trauma represents an increasingly important form of trauma due to the frequent use of firearms and bombs in civilian violence. We report our experience over the past 16 years with missile-induced cardiac injuries. A retrospective study reviewing 40 cases (30 males, 10 females) of missile cardiac injuries was conducted. The nature of injuries, management and outcomes were analyzed. The ages ranged from 14-68 years. The mean time in which patients reached the hospital was 4.1 hours. Forty percent of the patients had firearm injuries and the remaining 60% had pellet or splinter injuries to the heart. Survival was noted in 37.5% in the gunshot group and in 66.6% in the splinter/pellet group. The survival in patients with isolated cardiac injury was 60%, while it was only 40% in those with associated injuries. Single-chamber injury was noted in 87.5% of the patients and the survival in these was 62.8%. Fourteen complications were noted in the patients who were resuscitated. One patient was re-explored for excessive bleeding and a missed right ventricular perforation was repaired. In missile cardiac injuries, results are best if operated early, and outcome depends upon multiple factors including clinical status at arrival, time interval till management, nature of injury, and associated injuries.

An extrapleural hematoma (EH) is an uncommon and potentially life-threatening condition defined as the accumulation of blood in the extrapleural space between the parietal pleura and the endothoracic fascia. EH usually occurs after blunt thoracic trauma causing fractures of the sternum and ribs, which can tear the intercostal or internal mammary vessels. Typical radiological findings of EH are a biconvex opacity on the involved hemithorax and the so-called displaced "extrapleural fat sign." We present a case of a 36-year-old man with an isolated scapular fracture after a high-energy blunt chest trauma complicated with a large contralateral EH that was successfully managed nonoperatively with transcatheter arterial embolization (TAE) and image-guided drainage with a pig-tail catheter. To the best of our knowledge there is only one previous report describing a large EH after blunt thoracic trauma without rib fractures. Only two previous cases of large EHs have been treated initially with TAE, but both patients ultimately required open surgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients with EH can present with respiratory distress and hypotension, so early identification is important to facilitate proper treatment. EH has characteristic radiological findings, and contrast-enhanced computed tomography is not only the best imaging tool for confirming an EH, but also the best technique for detecting the source of the bleeding and other serious thoracic complications that may not be evident on chest x-ray studies.

Deep venous thrombosis (DVT) is common among trauma patients. If left untreated it may result in lethal pulmonary thromboembolism. Previous studies have suggested that intracranial hemorrhage serves as an independent risk factor for the development of DVT. These studies were not able to exclude anticoagulation therapy as a confounding variable in their analysis. Our objective was to determine the association of traumatic brain injury (TBI) to the formation of DVT irrespective of the use of anticoagulation therapy. All patients admitted to an academic level I Trauma Center between 2000 and 2007 with blunt or penetrating injuries were selected for inclusion in this study. Patients who died or who were discharged within 24 hours of admission were excluded in the analysis. TBI was defined as any intraparenchymal hemorrhage or extra-axial intracranial bleeding identified on radiographic imaging or both. Anticoagulation therapy was defined as the uninterrupted use of either subcutaneous lovenox or heparin. Risk ratios and 95% confidence intervals compared the risk of DVT among patients with and without TBI according to the initiation of anticoagulation therapy (no therapy, <24 hours, 24-48 hours, and >48 hours) adjusted for age, gender, race, injury severity, mechanism of injury, spinal injury, and lower extremity fracture. Irrespective of the time of initiation of pharmacologic prophylaxis, TBI is independently associated with the formation of DVT. A threefold to fourfold increased risk of DVT formation is consistent across all prophylaxis groups among patients with TBI. The incidence of DVT among injured patients with TBI is significantly higher than those patients without head injury independent of anticoagulation therapy. Rigorous surveillance to detect DVT among trauma patients with TBI should be undertaken and where appropriate alternate means for pulmonary thromboembolism prevention used.

Traumatic orbital CSF leak

2013-01-01

Compared to the cerebrospinalfluid (CSF) leak through the nose and ear, the orbital CSF leak is a rare and underreported condition following head trauma. We present the case of a 49-year-old woman with oedematous eyelid swelling and ecchymosis after a seemingly trivial fall onto the right orbit. Apart from the above, she was clinically unremarkable. The CT scan revealed a minimally displaced fracture of the orbital roof with no emphysema or intracranial bleeding. The fractured orbital roof in combination with the oedematous eyelid swelling raised the suspicion for orbital CSF leak. The MRI of the neurocranium demonstrated a small-sized CSF fistula extending from the anterior cranial fossa to the right orbit. The patient was treated conservatively and the lid swelling resolved completely after 5 days. Although rare, orbital CSF leak needs to be included in the differential diagnosis of periorbital swelling following orbital trauma. PMID:24323381

To determine whether prolonged (chronic) resuscitation has any beneficial effects on cardiac output and hepatocellular function after trauma-hemorrhage and acute fluid replacement. Acute fluid resuscitation after trauma-hemorrhage restores but does not maintain the depressed hepatocellular function and cardiac output. Male Sprague-Dawley rats underwent a 5-cm laparotomy (i.e., trauma was induced) and were bled to and maintained at a mean arterial pressure of 40 mmHg until 40% of maximal bleed-out volume was returned in the form of Ringer's lactate (RL). The animals were acutely resuscitated with RL using 4 times the volume of maximum bleed-out over 60 minutes, followed by chronic resuscitation of 0, 5, or 10 mL/kg/hr RL for 20 hours. Hepatocellular function was determined by an in vivo indocyanine green clearance technique. Hepatic microvascular blood flow was assessed by laser Doppler flowmetry. Plasma levels of interleukin-6 (IL-6) were determined by bioassay. Chronic resuscitation with 5 mL/kg/hr RL, but not with 0 or 10 mL/kg/hr RL, restored cardiac output, hepatocellular function, and hepatic microvascular blood flow at 20 hours after hemorrhage. The regimen above also reduced plasma IL-6 levels. Because chronic resuscitation with 5 mL/kg/hr RL after trauma-hemorrhage and acute fluid replacement restored hepatocellular function and hepatic microvascular blood flow and decreased plasma levels of IL-6, we propose that chronic fluid resuscitation in addition to acute fluid replacement should be routinely used in experimental studies of trauma-hemorrhage.

Primary hepatic artery embolization in pediatric blunt hepatic trauma.

Non-operative management of isolated blunt hepatic trauma is recommended except when hemodynamic instability requires immediate laparotomy. Hepatic artery angioembolization is increasingly used for hepatic injuries with ongoing bleeding as demonstrated by contrast extravasation on the CT scan. It is used primarily or after laparotomy to control ongoing hemorrhage. Hepatic angioembolization as part of multimodality management of hepatic trauma is reported mainly in adults, with few pediatric case reports. We describe our institution experience with primary pediatric hepatic angioembolization and review the literature with regard to indications and complications. Two cases (3 and 8 years old), with high-grade blunt hepatic injuries with contrast extravasation on the CT scan were successfully managed by emergency primary hepatic angioembolization with minimal morbidity and avoided laparotomy. To date, the only reports of pediatric hepatic angioembolization for trauma are 5 cases for acute bleeding and 15 delayed cases for pseudoaneurysm. The role of hepatic angioembolization in the presence of an arterial blush on CT in adults is accepted, but contested in a pediatric series, despite higher transfusion rate and mortality rate. We propose that hepatic angioembolization should be considered adjunct treatment, in lieu of, or in addition to emergency laparotomy for hemostasis in pediatric blunt hepatic injury.

To review indications, contraindications, and risks of using magnetic resonance imaging (MRI) in order to help primary care physicians refer patients appropriately for MRI, screen for contraindications to using MRI, and educate patients about MRI. Recommendations are based on classic textbooks, the policies of our MRI group, and a literature search using MEDLINE with the MeSH headings magnetic resonance imaging, brain, musculoskeletal, and spine. The search was limited to human, English-language, and review articles. Evidence in favour of using MRI for imaging the head, spine, and joints is well established. For cardiac, abdominal, and pelvic conditions, MRI has been shown useful for certain indications, usually to complement other modalities. For demonstrating soft tissue conditions, MRI is better than computed tomography (CT), but CT shows bone and acute bleeding better. Therefore, patients with trauma or suspected intracranial bleeding should have CT. Tumours, congenital abnormalities, vascular structures, and the cervical or thoracic spine show better on MRI. Either modality can be used for lower back pain. Cardiac, abdominal, and pelvic abnormalities should be imaged with ultrasound or CT before MRI. Contraindications for MRI are mainly metallic implants or shrapnel, severe claustrophobia, or obesity. With the increasing availability of MRI scanners in Canada, better understanding of the indications, contraindications, and risks will be helpful for family physicians and their patients.

It is often difficult to achieve stable fixation in Tile type C1 pelvic fractures and there is no standard fixation technique for these types of injuries. Iliac screw fixation can be used for treating Type C1 pelvic fractures. A retrospective review was performed on 47 patients who underwent iliac screw fixation in posterior column of ilium (PCI) for Tile type C1 pelvic fractures from July 2007 to December 2014. All patients were treated with fracture reduction, sacral nerve root decompression (if needed), internal fixation by iliac screw and connecting rod. The data on surgical time, intraoperative bleeding volume, postoperative neurologic functions and postoperative complications were analyzed. Patients were follow-up for at least 12months. The mean surgical time was 148minutes, and the mean intraoperative bleeding volume was 763ml. Patients were encouraged in-bed activities immediately after surgery. The postoperative Majeed functional score was 48-100 points (mean 80.2), corresponding to an excellent and good recovery of 91.5%. Postoperative X-radiographs and CT scans indicated satisfactory fracture reduction. Iliac screw fixation combined with sacral nerve canal decompression could effectively restore pelvic alignment and improve neurological functions for complex pelvic trauma.

Uterine arteriovenous malformations are rare and have been reported to occur after uterine trauma (eg, surgery, gestational trophoblastic disease, malignancy). A 33-year-old woman, gravida 3 para 3, presented 4 weeks post-cesarean delivery with episodic profuse vaginal bleeding. Pelvic ultrasonography and magnetic resonance imaging revealed a left uterine arteriovenous malformation. After consideration of all treatment options, total laparoscopic hysterectomy was performed. Acquired uterine arteriovenous malformations and placental ingrowth into the myometrium are increasingly reported after surgical uterine procedures. This case of a postpartum patient with both uterine arteriovenous malformation and retained placenta increta suggests a correlation between the two complications.

Spontaneous haemothorax is a subcategory of haemothorax that occurs in the absence of trauma or other causes. It is a rare emergency that can progress rapidly with massive blood loss leading to haemorrhagic shock and death. We describe a patient with massive spontaneous haemothorax caused by the disruption of an oesophageal artery from the middle segment of descending thoracic aorta. We sutured the bleeding artery in an emergency thoracotomy after the failure of interventional procedure. © The Author 2017.

Patients receiving warfarin who experience minor head injury are at risk of intracranial hemorrhage, and optimal management after a single head computed tomography (CT) scan is unclear. We evaluate a protocol of 24-hour observation followed by a second head CT scan. In this prospective case series, we enrolled consecutive patients receiving warfarin and showing no intracranial lesions on a first CT scan after minor head injury treated at a Level II trauma center. We implemented a structured clinical pathway, including 24-hour observation and a CT scan performed before discharge. We then evaluated the frequency of death, admission, neurosurgery, and delayed intracranial hemorrhage. We enrolled and observed 97 consecutive patients. Ten refused the second CT scan and were well during 30-day follow-up. Repeated CT scanning in the remaining 87 patients revealed a new hemorrhage lesion in 5 (6%), with 3 subsequently hospitalized and 1 receiving craniotomy. Two patients discharged after completing the study protocol with 2 negative CT scan results were admitted 2 and 8 days later with symptomatic subdural hematomas; neither received surgery. Two of the 5 patients with delayed bleeding at 24 hours had an initial international normalized ratio greater than 3.0, as did both patients with delayed bleeding beyond 24 hours. The relative risk of delayed hemorrhage with an initial international normalized ratio greater than 3.0 was 14 (95% confidence interval 4 to 49). For patients receiving warfarin who experience minor head injury and have a negative initial head CT scan result, a protocol of 24-hour observation followed by a second CT scan will identify most occurrences of delayed bleeding. An initial international normalized ratio greater than 3 suggests higher risk. Copyright © 2011 American College of Emergency Physicians. Published by Mosby, Inc. All rights reserved.

Sofocleous, Constantinos T., E-mail: constant@pol.net; Hinrichs, Clay; Hubbi, Basil

Purpose To evaluate the angiographic findings and embolotherapy in the management of traumatic renal arterial injury Methods This is a retrospective review of 22 patients with renal trauma who underwent arteriography and percutaneous embolization from December 1995 to January 2002. Medical records, imaging studies and procedural reports were reviewed to assess the type of injury, arteriographic findings and immediate embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians and by clinical chart review.Results Arteriography was performed in 125 patients admitted to a State Trauma Center with suspected internal bleeding. Renal arterial injury was documented in 22more » and was the result of a motor-vehicle accident (10), auto-pedestrian accident (1), gunshot (4) or stab wounds (6) and a fall (1). Percutaneous renal arterial embolization was undertaken in 22 of 125 (18%) patients to treat extravasation (11), arterial pedicle rupture (5), abnormal arteriovenous (3) or arteriocalyceal (2) communication and pseudoaneurysm (3). One of the pseudoaneurysms and one of the arteriovenous fistulae were found in addition to extravasation. All 22 patients (16 men, 6 women) were hemodynamically stable, or controlled during arteriography and embolotherapy. Selective and/or superselective embolization of the abnormal vessels was performed using coils in 9 patients, microcoils in 9 patients and Gelfoam pledgets in 3 patients. In one patient Gelfoam pledgets mixed with polyvinyl alcohol (PVA) particles were used for embolization. Immediate angiographic evidence of hemostasis was demonstrated in all cases. Two initial technical failures were treated with repeat arteriography and embolization. There was no procedure-related death. There was no non-target embolization. One episode of renal abscess after embolization was treated by nephrectomy and 3 patients underwent elective post-embolization nephrectomy to prevent infection. Follow-up ranged from 1 month to 7 years (mean 31 months). No procedure-related or delayed onset of renal insufficiency occurred.Conclusion In hemodynamically stable and controlled patients selective and superselective embolization is a safe and effective method for the management of renal vascular injury.« less

Rupture of the spleen can be secondary to abdominal traumas (usually closed trauma) or spontaneous, can interest an organ normal or with morphological alterations secondary to various pathologies. Among the diseases responsible of occult rupture, infectious diseases are the most frequent and, among these, infectious mononucleosis, that is complicated with splenic rupture in 0.5% of the cases, with 30% of mortality. P.M., 16 years old female, admitted with acute abdomen, progressive anaemia and incipient cardiovascular instability, associated with suggestive clinical diagnosis of infectious mononucleosis, confirmed by serological findings and histological examination. Because of the imaging of subcapsular splenic haematoma, probably ruptured and with peritoneal bleeding we opt for emergency laparotomy intraoperative findings allows to splenectomy. Splenic rupture in infectious mononucleosis often presents as left hypochondrial pain, rare in uncomplicated cases; its occurrence in a patient with a recent diagnosis of infectious mononucleosis or with clinical or laboratory features suggestive of acute EBV infection, should always be investigated with an urgent abdominal ultrasound scan or CT. This approach is mandatory when hypochondrial pain is associated with pain referred to the left shoulder (Kehr's sign), peritoneal irritation and haemodynamic instability. Patients with splenic rupture in infectious mononucleosis generally undergo emergency splenectomy.

BACKGROUND Fibrinogen plays a key role in hemostasis and is the first coagulation factor to reach critical levels in bleeding patients. Current European guidelines on the management of traumatic or perioperative bleeding recommend fibrinogen supplementation at specific threshold levels. Whole blood viscoelastic tests provide fast evaluation of fibrin deficits. Fast measurement of plasma fibrinogen concentration is not yet available. We investigated a method to rapidly determine whole blood fibrinogen concentration using standard Clauss assays and a steel ball coagulometer and provide an estimate of the “plasma-equivalent” fibrinogen concentration within minutes by adjustment of the measured whole blood fibrinogen concentration with a quickly measureable hemoglobin-derived hematocrit. METHODS The feasibility of this approach was tested with a Clauss assay using multiple porcine fresh blood samples obtained during in vivo bleeding, hemodilution, and after treatment with hemostatic therapy. Two different Clauss assays were then tested using multiple human volunteers’ blood samples diluted in vitro and supplemented with fibrinogen concentrate. Comparative measurements with fibrin-based thromboelastometry tests were performed. RESULTS Regression and Bland-Altman analyses of derived “plasma-equivalent” fibrinogen and measured plasma fibrinogen concentration was excellent in porcine and human blood samples, especially in the ranges relevant to traumatic or perioperative bleeding. CONCLUSION Fast whole blood fibrinogen measurements could be considered as an alternative to plasma fibrinogen measurement for acute bleeding management in trauma and perioperative care settings. Further studies are needed to prove this concept and determine the turnaround times for its clinical application in emergency departments and operating theaters. PMID:25742256

Gastrointestinal bleeding remains the leading cause of morbidity and mortality for patients who need hemodialysis treatment. Our aim was to evaluate patients who needed hemodialysis and presented with bleeding during their hospital stay (uremic bleeding patients). Factors that increased the risk of bleeding and death were evaluated. Additionally, uremic bleeding patients were compared to non-uremic bleeding patients regarding gastrointestinal findings. Fifty-one uremic bleeding patients were compared to two control groups which included uremic (hemodialysis dependent and non-bleeding) and non-uremic (no renal insufficiency and bleeding) patients. NSAIDs and anti-ulcer drug usage were more common in uremic bleeding and in uremic non-bleeding groups, respectively. Dialysis vintage was longer in uremic bleeding group. Comparison of uremic bleeding and non-bleeding uremic patients regarding the usage of ACEI or ARB drugs yielded non-significant results. Acute kidney injury, lower plasma albumin level and high CRP level were significantly increased the risk of mortality in uremic bleeding patients. Hospital stay more than 1 week was the only strong factor for mortality when multivariate analysis was performed. Gastroduodenal and duodenal ulcers were significantly detected in uremic bleeding and non-uremic bleeding patients; respectively. Hemodialysis patients presenting with gastrointestinal bleeding should be evaluated regarding use of prescriptions and efforts should be done in order to shorten their hospital stay and decrease their mortality. Effect of ACEI or ARB drugs should also be evaluated in future studies.

Contrast-enhanced ultrasound (CEUS) in blunt abdominal trauma

Baseline ultrasound is essential in the early assessment of patients with a huge haemoperitoneum undergoing an immediate abdominal surgery; nevertheless, even with a highly experienced operator, it is not sufficient to exclude parenchymal injuries. More recently, a new ultrasound technique using second generation contrast agents, named contrast-enhanced ultrasound (CEUS) has been developed. This technique allows all the vascular phase to be performed in real time, increasing ultrasound capability to detect parenchymal injuries, enhancing some qualitative findings, such as lesion extension, margins and its relationship with capsule and vessels. CEUS has been demonstrated to be almost as sensitive as contrast-enhanced CT in the detection of traumatic injuries in patients with low-energy isolated abdominal trauma, with levels of sensitivity and specificity up to 95%. Several studies demonstrated its ability to detect lesions occurring in the liver, spleen, pancreas and kidneys and also to recognize active bleeding as hyperechoic bands appearing as round or oval spots of variable size. Its role seems to be really relevant in paediatric patients, thus avoiding a routine exposure to ionizing radiation. Nevertheless, CEUS is strongly operator dependent, and it has some limitations, such as the cost of contrast media, lack of panoramicity, the difficulty to explore some deep regions and the poor ability to detect injuries to the urinary tract. On the other hand, it is timesaving, and it has several advantages, such as its portability, the safety of contrast agent, the lack to ionizing radiation exposure and therefore its repeatability, which allows follow-up of those traumas managed conservatively, especially in cases of fertile females and paediatric patients.

Severely injured patients experiencing hemorrhagic shock often require massive transfusion. Earlier transfusion with higher blood product ratios (plasma, platelets, and red blood cells), defined as damage control resuscitation, has been associated with improved outcomes; however, there have been no large multicenter clinical trials. To determine the effectiveness and safety of transfusing patients with severe trauma and major bleeding using plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio. Pragmatic, phase 3, multisite, randomized clinical trial of 680 severely injured patients who arrived at 1 of 12 level I trauma centers in North America directly from the scene and were predicted to require massive transfusion between August 2012 and December 2013. Blood product ratios of 1:1:1 (338 patients) vs 1:1:2 (342 patients) during active resuscitation in addition to all local standard-of-care interventions (uncontrolled). Primary outcomes were 24-hour and 30-day all-cause mortality. Prespecified ancillary outcomes included time to hemostasis, blood product volumes transfused, complications, incidence of surgical procedures, and functional status. No significant differences were detected in mortality at 24 hours (12.7% in 1:1:1 group vs 17.0% in 1:1:2 group; difference, -4.2% [95% CI, -9.6% to 1.1%]; P = .12) or at 30 days (22.4% vs 26.1%, respectively; difference, -3.7% [95% CI, -10.2% to 2.7%]; P = .26). Exsanguination, which was the predominant cause of death within the first 24 hours, was significantly decreased in the 1:1:1 group (9.2% vs 14.6% in 1:1:2 group; difference, -5.4% [95% CI, -10.4% to -0.5%]; P = .03). More patients in the 1:1:1 group achieved hemostasis than in the 1:1:2 group (86% vs 78%, respectively; P = .006). Despite the 1:1:1 group receiving more plasma (median of 7 U vs 5 U, P < .001) and platelets (12 U vs 6 U, P < .001) and similar amounts of red blood cells (9 U) over the first 24 hours, no differences between the 2 groups were found for the 23 prespecified complications, including acute respiratory distress syndrome, multiple organ failure, venous thromboembolism, sepsis, and transfusion-related complications. Among patients with severe trauma and major bleeding, early administration of plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio did not result in significant differences in mortality at 24 hours or at 30 days. However, more patients in the 1:1:1 group achieved hemostasis and fewer experienced death due to exsanguination by 24 hours. Even though there was an increased use of plasma and platelets transfused in the 1:1:1 group, no other safety differences were identified between the 2 groups. clinicaltrials.gov Identifier: NCT01545232.

Exsanguination, which was the predominant cause of death within the first 24 hours, was significantly decreased in the 1:1:1 group (9.2% vs 14.6% in 1:1:2 group; difference, −5.4% [95% CI, −10.4% to −0.5%]; P = .03). More patients in the 1:1:1 group achieved hemostasis than in the 1:1:2 group (86% vs 78%, respectively; P = .006). Despite the 1:1:1 group receiving more plasma (median of 7 U vs 5 U, P < .001) and platelets (12 U vs 6 U, P < .001) and similar amounts of red blood cells (9 U) over the first 24 hours, no differences between the 2 groups were found for the 23 prespecified complications, including acute respiratory distress syndrome, multiple organ failure, venous thromboembolism, sepsis, and transfusion-related complications. CONCLUSIONS AND RELEVANCE Among patients with severe trauma and major bleeding, early administration of plasma, platelets, and red blood cells in a 1:1:1 ratio compared with a 1:1:2 ratio did not result in significant differences in mortality at 24 hours or at 30 days. However, more patients in the 1:1:1 group achieved hemostasis and fewer experienced death due to exsanguination by 24 hours. Even though there was an increased use of plasma and platelets transfused in the 1:1:1 group, no other safety differences were identified between the 2 groups.

Patients with hemorrhagic shock and/or trauma are at risk of developing colonic ischemia associated with bacterial translocation that may lead to multiple organ failure and death. Intestinal ischemia is difficult to diagnose noninvasively. The present retrospective study was designed to determine whether circulating plasma D-lactate is associated with mortality in a clinically relevant two-hit model in baboons. Hemorrhagic shock was induced in anesthetized baboons (n = 24) by controlled bleeding (mean arterial pressure, 40 mmHg), base excess (maximum -5 mmol/L), and time (maximum 3 h). To mimic clinical setting more closely, all animals underwent a surgical trauma after resuscitation including midshaft osteotomy stabilized with reamed femoral interlocking nailing and were followed for 7 days. Hemorrhagic shock/surgical trauma resulted in 66% mortality by day 7. In nonsurvivor (n = 16) hemorrhagic shock/surgical trauma baboons, circulating D-lactate levels were significantly increased (2-fold) at 24 h compared with survivors (n = 8), whereas the early increase during hemorrhage and resuscitation declined during the early postresuscitation phase with no difference between survivors and nonsurvivors. Moreover, D-lactate levels remained elevated in the nonsurvival group until death, whereas it decreased to baseline in survivors. Prediction of death (receiver operating characteristic test) by D-lactate was accurate with an area under the curve (days 1-3 after trauma) of 0.85 (95% confidence interval, 0.72-0.93). The optimal D-lactate cutoff value of 25.34 μg/mL produced sensitivity of 73% to 99% and specificity of 50% to 83%. Our data suggest that elevation of plasma D-lactate after 24 h predicts an increased risk of mortality after hemorrhage and trauma.

A Case of Traumatic Mesenteric Bleeding Controlled by only Transcatheter Arterial Embolization

We report a case of mesenteric hematoma following blunt abdominal trauma that was successfully treated with transcatheter arterial embolization (TAE) and did not require surgical repair. A 43-year-old man with blunt abdominal trauma caused in a factory accident was admitted with a stable general condition and laboratory data. On CT examination, a large mesenteric hematoma with extravasation of contrast media was observed. TAE was first attempted to control the bleeding. A superior mesenteric angiogram showed extravasation of contrast medium from a branch of the ileocolic artery and obstruction of the cecal branch. After successful TAE using microcoils, the distal portionmore » of the cecal branch was still preserved via collateral circulation. No abdominal symptoms have occurred during the 7 months following TAE. In mesenteric injury cases with limited intestinal damage, TAE may therefore be a reasonable alternative to emergent laparotomy.« less

Transcatheter Arterial Embolization for Spontaneous Rupture of the Omental Artery

DOE Office of Scientific and Technical Information (OSTI.GOV)

Matsumoto, Tomohiro, E-mail: t-matsu@koto.kpu-m.ac.jp; Yamagami, Takuji; Morishita, Hiroyuki

We encountered a rare case of spontaneous rupture of the omental artery. A 25-year-old man without any episode of abdominal trauma or bleeding disorders came to the emergency unit with left upper abdominal pain. Hematoma with extravasation of the greater omentum and a hemoperitoneum was confirmed on abdominal contrast-enhanced computed tomography. Bleeding from the omental artery was suspected based on these findings. Transcatheter arterial embolization was successfully performed after extravasation of the omental artery, which arises from the left gastroepiploic artery, was confirmed on arteriography. Partial ometectomy was performed 10 days after transcatheter arterial embolization, revealing that the hematoma measuredmore » 10 cm in diameter in the greater omentum. Pathological examination showed rupture of the branch of an omental artery without abnormal findings, such as an aneurysm or neoplasm. Thus, we diagnosed him with spontaneous rupture of the omental artery. The patient recovered and was discharged from the hospital 10 days after the surgery, with a favorable postoperative course.« less

Video-assisted minithoracotomy for blunt diaphragmatic rupture presenting as a delayed hemothorax.

Ota, Hideki; Kawai, Hideki; Matsuo, Tsubasa

2014-01-01

Diaphragmatic ruptures after blunt trauma are rare life-threatening conditions. Most of them occur on the left-sided hemidiaphragm with herniation or associated organ injuries after a motor vehicle accident. We present an unusual case of blunt diaphragmatic rupture resulting in a delayed hemothorax. A 62-year-old man presented with acute dyspnea that initiated while straining to pass stool. He had a bruise on the lower back region of his right thorax after a slip-and-fall accident 7 days previously. Chest computed tomographic scans revealed a right-sided hemothorax without any evidence of herniation or associated organ injuries. Emergency surgery was performed through a video-assisted minithoracotomy. During surgery, we identified a diaphragmatic laceration with a severed blood vessel originating from the right superior phrenic artery. The lesion was repaired with interrupted horizontal mattress sutures. The total amount of bleeding was approximately 2000 mL. The patient had an uneventful recovery with no further bleeding episodes.

Pelvic fractures are severe injuries with frequently associated multi-system trauma and a high mortality rate. The value of the pelvic fracture pattern for predicting transfusion requirements and mortality is not entirely clear. To address hemorrhage from pelvic injuries, the early application of pelvic binders is now recommended and arterial angio-embolization is widely used for controlling arterial bleeding. Our aim was to assess the association of the pelvic fracture pattern according to the Tile classification system with transfusion requirements and mortality rates, and to evaluate the correlation between the use of pelvic binders and arterial angio-embolization and the mortality of patients with pelvic fractures. Single-center retrospective cohort study including all consecutive patients with a pelvic fracture from January 2008 to June 2015. All radiological fracture patterns were independently reviewed and grouped according to the Tile classification system. Data on patient demographics, use of pelvic binders and arterial angio-embolization, transfusion requirements and mortality were extracted from the institutional trauma registry and analyzed. The present study included 228 patients. Median patient age was 43.5 years and 68.9% were male. The two independent observers identified 105 Tile C (46.1%), 71 Tile B (31.1%) and 52 Tile A (22.8%) fractures, with substantial to almost perfect interobserver agreement (Kappa 0.70-0.83). Tile C fractures were associated with a higher mortality rate (p = 0.001) and higher transfusion requirements (p < 0.0001) than Tile A or B fractures. Arterial angio-embolization for pelvic bleeding (p = 0.05) and prehospital pelvic binder placement (p = 0.5) were not associated with differences in mortality rates. Tile C pelvic fractures are associated with higher transfusion requirements and a higher mortality rate than Tile A or B fractures. No association between the use of pelvic binders or arterial angio-embolization and survival was observed in this cohort of patients with pelvic fractures.

CT of trauma to the abnormal kidney

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rhyner, P.; Federle, M.P.; Jeffrey, R.B.

Traumatic injuries to already abnormal kidneys are difficult to assess by excretory urography and clinical evaluation. Bleeding and urinary extravasation may accompany minor trauma; conversely, underlying tumors, perirenal hemorrhage, and extravasation may be missed on urography. Computed tomography (CT) was performed in eight cases including three neoplasms, one adult polycystic disease, one simple renal cyst, two hydronephrotic kidneys, and one horseshoe kidney. CT provided specific and clinically useful information in each case that was not apparent on excretory urography.

Recombinant activated factor VII: its mechanism of action and role in the control of hemorrhage.

Allen, Geoffrey A; Hoffman, Maureane; Roberts, Harold R; Monroe, Dougald M

2002-12-01

Recombinant activated factor VII (rFVIIa) has proven both safe and efficacious in the treatment of bleeding episodes in patients with hemophilia A or B who have developed inhibitors. More recently, a growing number of reports suggests that rFVIIa may also have indications for the treatment of bleeding in patients with other hemostatic disorders, including qualitative and quantitative platelet defects, factor deficiencies other than hemophilia, and in otherwise healthy patients with uncontrollable hemorrhage following surgery or trauma. We have attempted to reconcile the various proposed mechanisms of action of rFVIIa with its apparent efficacy in such diverse clinical settings. A review of the literature was performed to determine those clinical scenarios in which rFVIIa appears to have been effective in controlling associated hemorrhage. Findings from our group and others have demonstrated that rFVIIa is able to directly activate factor X and increase thrombin production on the surface of activated platelets in the absence of factor VIII or IX, as well as to improve thrombin generation in thrombocytopenia, and to yield a fibrin dot more resistant to fibrinolysis in vitro. Through these primary mechanisms, we believe that rFVIIa may be able to compensate for a variety of defects in hemostasis and merits further investigation as a general therapeutic for uncontrollable hemorrhage.

The purpose of this study is to review our postoperative outcomes with liver packing in complex abdominal trauma. 76 liver trauma were admitted for operative procedures in the Surgical Department of City Hospital Timisoara between April 1994 - September 2009 and 16 cases were identified in our series as requiring liver packing. In all cases, this method was efficient, with no postoperative bleeding. In the same time, there were specific complications such as bile leak or abdominal collections. despite a second procedure for packs removal and the possibility for specific complications, liver packing is an efficient method for severe liver trauma or complex abdominal lesions.

Background Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. Material/Methods A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. Results A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13.1); 164 (85.9%) were males. Traffic-related accident was the main mechanism of injury. Splenic contusion and hematoma (77.2%) was the most frequent finding on initial computerized tomography (CT) scans, followed by shattered spleen (11.1%), blush (11.1%), and devascularization (0.6%). Repeated CT scan revealed 3 patients with pseudoaneurysm who underwent angioembolization. Nearly a quarter of patients were managed surgically. Non-operative management failed in 1 patient who underwent splenectomy. Patients with grade V injury presented with higher mean ISS and abdominal AIS, required frequent blood transfusion, and were more likely to be FAST-positive (p=0.001). The majority of low-grade (I–III) splenic injuries were treated conservatively, while patients with high-grade (IV and V) BSI frequently required splenectomy (p=0.001). Adults were more likely to have grade I, II, and V BSI, blood transfusion, and prolonged ICU stay as compared to pediatric BSI patients. The overall mortality rate was 7.9%, which is mainly association with traumatic brain injury and hemorrhagic shock; half of the deaths occurred within the first day after injury. Conclusions Most BSI patients had grade I–III injuries that were successfully treated non-operatively, with a low failure rate. The severity of injury and presence of associated lesions should be carefully considered in developing the management plan. Thorough clinical assessment and CT scan evaluation are crucial for appropriate management of BSI. PMID:28700540

The aim of our study was to investigate the hemostatic mechanism underlying microbubble-enhanced non-focused ultrasound treatment of liver trauma. Thirty rabbits with liver trauma were randomly divided into three groups—the microbubble-enhanced ultrasound (MEUS; further subdivided based on exposure intensity into MEUS1 [0.11 W/cm2], MEUS2 [0.55 W/cm2], and MEUS3 [1.1 W/cm2]), ultrasound without microbubbles (US), and microbubbles without ultrasound (MB) groups. The pre- and post-treatment bleeding weight and visual bleeding scores were evaluated. The serum liver enzyme concentrations as well as the blood perfusion level represented by mean peak contrast intensity (PI) ratio in the treatment area were analyzed. The hemostatic mechanism was evaluated by histological and transmission electron microscopic examination of liver tissue samples. The MEUS subgroups 1–3 (grade 0–1, grade 0–2, and grade 1–2, respectively) exhibited significantly lower post-treatment visual bleeding scores than the US and MB groups (both, grade 3–4; all, P < 0.05). Subgroups MEUS1 (0.346 ± 0.345 g) and MEUS2 (2.232 ± 2.256 g) exhibited significantly lower post-treatment bleeding weight than the US and MB groups (5.698 ± 1.938 and 5.688 ± 2.317 g, respectively; all, P < 0.05). Additionally, MEUS subgroups 1–3 exhibited significantly lower post-treatment blood perfusion levels (PI ratios, 0.64 ± 0.085, 0.73 ± 0.045, and 0.84 ± 0.034, respectively) than the US and MB groups (PI ratios, 1.00 ± 0.005 and 0.99 ± 0.005, respectively; all, P < 0.05). In the MEUS group, hepatic cells became edematous and compressed the hepatic sinus and associated blood vessels. However, the serum liver enzyme levels were not significantly altered. Microbubble-enhanced non-focused ultrasound does not significantly affect blood perfusion and liver function and can be used to induce rapid hemostasis in case of liver trauma. PMID:27633577

The aim of this study was to identify the predictive factors influencing mortality in patients with bleeding Mallory-Weiss syndrome in comparison with peptic ulcer bleeding. Between January 2005 and December 2009, 281 patients with endoscopically confirmed Mallory-Weiss syndrome and 1530 patients with peptic ulcer bleeding were consecutively evaluated. The 30-day mortality and clinical outcome were related to the patients' demographic data, endoscopic, and clinical characteristics. The one-year cumulative incidence for bleeding Mallory-Weiss syndrome was 7.3 cases/100,000 people and for peptic ulcer bleeding 40.4 cases/100,000 people. The age-standardized incidence for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding remained unchanged during the observational five-year period. The majority of patients with bleeding Mallory-Weiss syndrome were male patients with significant overall comorbidities (ASA class 3-4). Overall 30-day mortality rate was 5.3% for patients with bleeding Mallory-Weiss syndrome and 4.6% for patients with peptic ulcer bleeding (p = 0.578). In both patients with bleeding Mallory-Weiss syndrome and peptic ulcer bleeding, mortality was significantly higher in patients over 65 years of age and those with significant overall comorbidities (ASA class 3-4). The incidence of bleeding Mallory-Weiss syndrome and peptic ulcer bleeding has not changed over a five-year observational period. The overall 30-day mortality was almost equal for both bleeding Mallory-Weiss syndrome and peptic ulcer bleeding and was positively correlated to older age and underlying comorbid illnesses.

Over the past two decades, transcatheter arterial embolization has become the first-line therapy for the management of upper gastrointestinal bleeding that is refractory to endoscopic hemostasis. Advances in catheter-based techniques and newer embolic agents, as well as recognition of the effectiveness of minimally invasive treatment options, have expanded the role of interventional radiology in the management of hemorrhage for a variety of indications, such as peptic ulcer bleeding, malignant disease, hemorrhagic Dieulafoy lesions and iatrogenic or trauma bleeding. Transcatheter interventions include the following: selective embolization of the feeding artery, sandwich coil occlusion of the gastroduodenal artery, blind or empiric embolization of the supposed bleeding vessel based on endoscopic findings and coil pseudoaneurysm or aneurysm embolization by three-dimensional sac packing with preservation of the parent artery. Transcatheter embolization is a fast, safe and effective, minimally invasive alternative to surgery when endoscopic treatment fails to control bleeding from the upper gastrointestinal tract. This article reviews the various transcatheter endovascular techniques and devices that are used in a variety of clinical scenarios for the management of hemorrhagic gastrointestinal emergencies.

The role of nonoperative management for penetrating kidney injuries is unknown. Therefore, we review the management and outcome of penetrating kidney injuries at a center with a high incidence of penetrating trauma. Data from all patients presenting with hematuria and/or kidney injury discovered on imaging or at surgery admitted to the trauma center at Groote Schuur Hospital in Cape Town, South Africa during a 19-month period (January 2007 to July 2008) were prospectively collected and reviewed. These data were analyzed for demographics, injury mechanism, perioperative management, nephrectomy rate and nonoperative success. Patients presenting with hematuria and with an acute abdomen underwent a single shot excretory urogram. Those presenting with hematuria without an indication for laparotomy underwent computerized tomography with contrast material. A total of 92 patients presented with hematuria following penetrating abdominal trauma. There were 75 (80.4%) proven renal injuries. Of the patients 84 were men and the median age was 26 years (range 14 to 51). There were 50 stab wounds and 42 gunshot renal injuries. Imaging modalities included computerized tomography in 60 cases and single shot excretory urography in 18. There were 9 patients brought directly to the operating room without further imaging. A total of 47 patients with 49 proven renal injuries were treated nonoperatively. In this group 4 patients presented with delayed hematuria, of whom 1 had a normal angiogram and 3 underwent successful angioembolization of arteriovenous fistula (2) and false aneurysm (1). All nonoperatively managed renal injuries were successfully treated without surgery. There were 18 nephrectomies performed for uncontrollable bleeding (11), hilar injuries (2) and shattered kidney (3). Post-nephrectomy complications included 1 infected renal bed hematoma requiring percutaneous drainage. Of the injuries found at laparotomy 12 were not explored, 2 were drained and 5 were treated with renorrhaphy. Penetrating trauma is associated with a high nephrectomy rate (24.3%). However, a high nonoperative success rate (100%) is achievable with minimal morbidity (9%). Copyright © 2012 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Gegel, Brian; Burgert, James; Loughren, Michael; Johnson, Don

2012-01-01

The purpose of this study was to examine the effectiveness of the hemostatic agent BleedArrest compared to control. This was a prospective, experimental design employing an established porcine model of uncontrolled hemorrhage. The minimum number of animals (n=10 per group) was used to obtain a statistically valid result. There were no statistically significant differences between the groups (P>.05) indicating that the groups were equivalent on the following parameters: activating clotting time, the subject weights, core body temperatures, amount of one minute hemorrhage, arterial blood pressures, and the amount and percentage of total blood volume. There were significant differences in the amount of hemorrhage (P=.033) between the BleedArrest (mean=72, SD±72 mL) and control (mean=317.30, SD±112.02 mL). BleedArrest is statistically and clinically superior at controlling hemorrhage compared to the standard pressure dressing control group. In conclusion, BleedArrest is an effective hemostatic agent for use in civilian and military trauma management.

The objectives of this paper were to investigate the clinicopathological characteristics and prognostic factors of GI-bleeding GIST patients and explore whether GI bleeding is a risk factor for GIST relapse. Primary GIST patients with initial symptoms of GI bleeding or no GI bleeding were retrospectively studied. Up to 178 GI-bleeding GIST patients including 108 (60.7%) males and 70 (39.3%) females were evaluated for the clinicopathological characteristics. The stomach, small bowel, and colorectum were the tumor sites in 82 (46.1%), 85 (47.8%), and 11 (6.2%) patients. Of the 178 patients, 163 GI-bleeding patients had follow-up while another 363 patients from the total population presented without GI bleeding were followed up. Up to 526 patients who received postoperative follow-up were included in the survival analysis. Compared with the 363 non-GI-bleeding patients, GI-bleeding patients developed smaller tumors (P = 0.015) and had a longer relapse-free survival (RFS; P = 0.014). For the 163 GI-bleeding patients, a Cox regression analysis showed that the mitotic count and the platelet-lymphocyte ratio before surgery were independent prognostic predictors for poor outcome regarding RFS. For all 526 patients, a Cox regression analysis indicated that tumor location, mitotic index, platelet-lymphocyte ratio, and GI bleeding were independent prognosis predictors. Compared to non-GI-bleeding GIST patients, patients with GI bleeding were more likely to be male and to have more small intestine GISTs, smaller tumors, and a longer RFS. For GI-bleeding patients, mitotic count and platelet-lymphocyte ratio were independent prognostic indicators. GI bleeding served as a surrogate for smaller GIST and was a protective factor for GIST recurrence.

Hemoperitoneum with hypovolemic shock from avulsion of a pedunculated leiomyoma is a rare but highly fatal condition that can occur spontaneously or as a result of trauma. We report a case of hemoperitoneum and hypovolemic shock secondary to a bleeding leiomyoma detected via computed tomography (CT) scan in a 39 year old premenopausal, gravida 0 female that presented with abdominal pain and became hemodynamically unstable in the emergency department. A preoperative bimanual exam revealed a mass consistent with a 20 week gestational uterus. Following fluid resuscitation, the patient underwent emergent myomectomy and ligation of the right uterine artery and was discharged home in good condition.

To evaluate the performance of dental implant-supported telescopic crown (TC)-retained overdentures to restore the oral function of patients who have insufficient jawbone volume resulting from tumor resection or trauma. From January 2004 to December 2008, implant-supported TC-retained overdentures were used to restore the oral function of patients with severe bony defects resulting from tumor resection or trauma. Clinical data, including implant success and survival rates, biologic and mechanical complications, prosthodontic maintenance efforts, and patient satisfaction, were analyzed annually after delivery of the final prostheses. Twenty-four patients were treated, and a total of 88 implants were inserted to support TC-retained overdentures. The mean modified plaque index of implants remained low (<20%), and the majority of implants (>76.3%) in the study showed the absence of bleeding on probing at follow-up visits. Peri-implant marginal bone loss (MBL) ranged from 0.8 to 1.2 mm. There was no statistically significant difference in the MBL between maxillary and mandibular implants (P = .43). The implant success rate was 100% after 5 years, and the prosthodontic maintenance and complication rate was 0.22 times per year. More than 90% of patients were satisfied with the restoration of their oral function using TCs. Based on our study of 24 patients treated with TC-retained overdentures, it appears that this treatment may be a viable option for patients with insufficient jawbone volume.

In the German population, the percentage of elderly patients is increasing, and consequently there are more elderly patients among trauma cases, and particularly cases of polytrauma. The aim of this study was to present clinical results and a risk profile for geriatric polytrauma patients. Review of 140 geriatric (over 65 years of age) polytrauma patients who received prehospital treatment was performed. Severity of trauma was retrospectively assessed with Hannover Polytrauma Score (HPTS). Age, hemoglobin (Hb) level, systolic blood pressure (BP), Glasgow Coma Scale (GCS) score, timing of and necessity for intubation were analyzed in relation to mortality and in comparison with younger patients. Geriatric polytrauma patients (n=140) had overall mortality rate of 65%, whereas younger patients (n=1468) had mortality rate of 15.9%. Despite equivalent severity of injury (HPTS less age points) in geriatric and non-geriatric groups, mortality rate was 4 times higher in geriatric group. Major blood loss with Hb <8 g/dL was revealed to be 3 times more fatal than moderate or minor blood loss (Hb ≥8 g/dL). GCS score <12 corresponded to double mortality rate (39% vs 83%). Age by itself is significant risk factor and predictor of increased mortality in polytrauma patients. Additional risk factors include very low GCS score and systolic BP <80 mm Hg, for instance, as potential clinical indicators of massive bleeding and traumatic brain injury. Such parameters demand early and rapid treatment at prehospital stage and on admission.

Emergency pancreatico-duodenectomy(EPD) is a very rare procedure and few reports are present in medical literature. It is an uncommon approach, usually used for emergency surgical treatment of abdominal trauma that involves the head of the pancreas or the duodenum, but it is also a surgical tool for the treatment of ruptured aneurysms, bleeding pseudocysts, duodenal perforations, uncontrollable hemorrhage from ulcers and tumors, severe infectious complications of acute pancreatitis or endoscopic retrograde cholangiopancreatography related complications (1,2). It is rarely used as the first line of treatment in case of acute bleeding from arterial pseudoaneurysm of the cephalad region of the pancreas. We present the case of a bleeding pseudoaneurysm of the cefalic region of the pancreas in a young patient with previously undiagnosed chronic pancreatitis and with suspicion of a malignant process located in the head of the pancreas. We performed a pancreatico-duodenectomy with resection of superior mesenteric and portal vein with reconstruction using Gore-Tex vascular graft due to probable venous abutment. Postoperative course was without any major complications, only minor grad-I pancreatic fistula was present. We determine that EPD is a useful tool in the treatment of such cases. It can be used as a first line of treatment or secondary to endovascular stenting or embolization. Celsius.

Retained haemothorax and pneumothorax are the most common complications after blunt chest traumas. Lung lacerations derived from fractures of the ribs are usually found in these patients. Video-assisted thoracoscopic surgery (VATS) is usually used as a routine procedure in the treatment of retained pleural collections. The objective of this study was to find out if there is any advantage in adding the procedure for repairing lacerated lungs during VATS. Patients who were brought to our hospital with blunt chest trauma were enrolled into this prospective cohort study from January 2004 to December 2011. All enrolled patients had rib fractures with type III lung lacerations diagnosed by CT scans. They sustained retained pleural collections and surgical drainage was indicated. On one group, only evacuation procedure by VATS was performed. On the other group, not only evacuations but also repair of lung injuries were performed. Patients with penetrating injury or blunt injury with massive bleeding, that required emergency thoracotomy, were excluded from the study, in addition to those with cardiovascular or oesophageal injuries. During the study period, 88 patients who underwent thoracoscopy were enrolled. Among them, 43 patients undergoing the simple thoracoscopic evacuation method were stratified into Group 1. The remaining 45 patients who underwent thoracoscopic evacuation combined with resection of lung lacerations were stratified into Group 2. The rates of post-traumatic infection were higher in Group 1. The durations of chest-tube drainage and ventilator usage were shorter in Group 2, as were the lengths of patient intensive care unit stay and hospital stay. When compared with simple thoracoscopic evacuation methods, repair and resection of the injured lungs combined may result in better clinical outcomes in patients who sustained blunt chest injuries. © The Author 2013.

We describe a case of methaemoglobinaemia (MtHb) in a previously healthy 39-year-old gentleman who presented with a traumatic glass laceration to his right wrist that required emergency surgery to control bleeding and repair his ulnar artery. The MtHb was noted on blood gas analysis by the anaesthetist after the patient had a drop in arterial oxygen saturation under general anaesthetic. We initially suspected the lidocaine local anaesthetic injected proximal to his wound for pain control in the emergency department an hour preoperatively, but then discovered that the patient was a recreational user of 'poppers' and had in fact been using these drugs just before his injury and hospitalisation. The patient's condition stabilised overnight with conservative management. Given how commonly hand surgeons and other clinical staff use local anaesthetics, we reviewed the literature on this uncommon, but potentially fatal, complication, its causes and evidence-based management.

Incidence of Gastrointestinal Bleeding After Percutaneous Coronary Intervention: A Single Center Experience.

PubMed

Aziz, Fahad

2014-02-01

Gastrointestinal (GI) bleeding is a hemorrhagic complication after percutaneous coronary intervention in patients with acute myocardial infarction. The purpose of the study is to determine predictors of GI bleeding and impact of GI bleeding on the patients undergoing percutaneous coronary intervention. GI bleeding occurred in 6 (7.1%) of 84 patients with STEMI/NSETMI (ST-segment elevated myocardial infarction/Non ST-segment elevated myocardial infarction) undergoing primary percutaneous coronary intervention. Univariate analysis demonstrates that patients with GI bleeding had a significantly higher previous GI bleeding (16.66% vs. 8.6%, P < 0.001). Higher Killip classification at presentation was associated with higher incidence of GI bleeding (61% vs. 18%, P < 0.01). The use of proton pump inhibitors did not reduce the risk of GI bleeding. The GI bleeding in these patients was associated with higher mortality and morbidity in the post percutaneous coronary intervention period. Although, GI bleeding in patients with MI significantly increases mortality and morbidity, previous GI bleeding and higher Killip class are associated with higher incidence of GI bleeding. High-risk patients for GI bleeding can be identified at presentation.

Multiple trauma in children is rare so that even large trauma centers will only treat a small number of cases. Nevertheless, accidents are the most common cause of death in childhood whereby the causes are mostly traffic accidents and falls. Head trauma is the most common form of injury and the degree of severity is mostly decisive for the prognosis. Knowledge on possible causes of injury and injury patterns as well as consideration of anatomical and physiological characteristics are of great importance for treatment. The differences compared to adults are greater the younger the child is. Decompression and stopping bleeding are the main priorities before surgical fracture stabilization. The treatment of a severely injured child should be carried out by an interdisciplinary team in an approved trauma center with expertise in pediatrics. An inadequate primary assessment involves a high risk of early mortality. On the other hand children have a better prognosis than adults with comparable injuries.

Oral trauma and dental emergency management recommendations of first-aid textbooks and manuals.

PubMed

Zadik, Yehuda

2007-10-01

The recommendations of oral trauma and dental emergencies management of nine first-aid textbooks and manuals from the last two decades were evaluated. Only one book includes all the relevant topics: dental anatomy, management of tooth luxations and avulsion, tooth fracture, mandible dislocation, jaw fracture, intraoral bleeding and dental pain. Two books recommend self-replantation of an avulsed tooth, but four books detail the storage media and evaluate the importance of a quick referral to a dental surgery. In three first-aid books, the only mention of oral trauma is the hazard of choking from tooth fragments, and in one other book, only mandible dislocation is mentioned as oral trauma. The insufficient information of oral trauma management in these first-aid texts partly explains the previous reports of poor and inadequate knowledge in that topic among medics, teachers and the general public.

One hundred forty-four critically ill patients admitted to an intensive care setting were randomly assigned to cimetidine or antacid treatament groups. Gastric pH was monitored hourly. One hundred twenty-three (85%) patients demonstrated a fall in pH to less than 4 and were considered to require prophylaxis. Prophylaxis was considered adequate if the measured pH could then be maintained at greater than or equal to 4. Fifty-eight patients received antacids alone, the average requirement being 41 cc/hour. Sixty-five patients received cimetidine. Seventeen (26%) of the cimetidine prophylaxis patients failed to raise their pH and were than placed on hourly administration of antacid with successful elevations of pH to greater than or equal to 4 in all cases on an average supplementary dose of 53 cc/hour. Risk factors, including sepsis, hypotension, head injury, respiratory failure, degree of trauma, and age, were not statistically different in the two treated groups. Using these same criteria, responders to cimetidine could not be differentiated from nonresponders. All patients were protected from significant stress bleeding while on this study. Significant complications of either treatment were minimal. Antacids offered consistent protection against gastric acidity and were 100% effective. A routine schedule of 300 mg every six hours of cimetidine was effective in only 47% of patients, and the maximum dose of cimetidine was effective in only 74% of patients. Hourly measurement of intragastric pH is required for monitoring the response to prophylaxis of stress bleeding in severely ill patients. PMID:7406571

The early use of blood products has been associated with improved patient outcomes following severe hemorrhage or traumatic injury. We aimed to investigate the influence of pre-hospital blood products (i.e. plasma and/or RBCs) on admission hemostatic properties and patient outcomes. We hypothesized that pre-hospital plasma would improve hemostatic function as evaluated by rapid thrombelastography (rTEG). We conducted a prospective observational study recruiting 257 trauma patients admitted to a Level I trauma center having received either blood products pre-hospital or in-hospital within 6 hours of admission. Clinical data on patient demographics, blood biochemistry, injury severity score and mortality were collected. Admission rTEG was conducted to characterize the coagulation profile and hemostatic function. 75 patients received pre-hospital plasma and/or RBCs (PH group; nearly half received both RBCs and plasma) whereas 182 patients only received in-hospital blood products (RBCs, Plasma and Platelets) within 6 hours of admission (IH group). PH patients had lower Glasgow coma scale (GCS) scores, more penetrating injuries, lower systolic blood pressures, lower hemoglobin levels, lower platelet counts and greater acidosis upon ED admission than the IH group (all p < 0.05). Despite differences in type of injury and admission vitals indicating that the PH group had more signs of bleeding than the IH group, there were no significant differences in in-hospital mortality (PH 26.7% vs. IH 20.9% p = 0.31). When comparing rTEG variables between PH patients transfused with 0, 1 or 2 units of plasma, more pre-hospital plasma transfusion was tendency towards improved rTEG variables. When adjusting for pre-hospital RBC, pre-hospital plasma was associated with significantly higher rTEG MA (p = 0.012) at hospital admission. After adjusting for pre-hospital RBCs, pre-hospital plasma transfusion was independently associated with increased rTEG MA, as well as arrival indices of shock and hemodynamic instability. Besides more severe injury and worse clinical presentation, the group that received pre-hospital transfusion had early and late mortality similar to patients not transfused pre-hospital. These data suggest that early administration of plasma can provide significant hemostatic and potential survival benefit to severely hemorrhaging trauma patients.

Dislocation of the mandibular condyle into the middle cranial fossa causing an epidural haematoma.

Dislocation of the mandibular condyle into the middle cranial fossa is a rare complication of mandibular trauma due to anatomical and biomechanical factors. Owing to the proximity of the temporal glenoid fossa to the middle meningeal artery, there is the risk of serious sequelae in case of trauma. The authors report the case of a 36-year-old male patient, who was beaten up in a family dispute and presented with complex mandibular and maxillofacial fractures, including mandibular condyle intrusion into the middle cranial fossa causing extensive meningeal bleeding. The patient underwent immediate surgery, with evacuation of the epidural haematoma via a temporal approach. In addition open reduction and reconstruction of the temporal glenoid fossa via anatomic reduction of the fragments was performed. A functional occlusion was re-established via miniplate reconstruction of the complex mandibular body and ramus fractures. Prompt diagnosis and a multidisciplinary approach are essential to minimize the complications. Advanced imaging modalities of computed tomography are indicated. Treatment options should be individualized in particular in case of suspected neurological injury. Copyright © 2011 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

Spontaneous hemothorax is a well-known yet seldom-reported entity in forensic literature. While trauma-related hemothorax is frequently encountered in a medicolegal setting, non-traumatic and spontaneous hemothorax are relatively uncommon entities. The wide range of causes that can trigger fatal intrathoracic bleeding include thoracic aortic dissection, followed by vascular malformations, various oncological diseases, and connective tissue abnormalities. In rare instances, extramedullary hematopoiesis, ectopic pregnancy, congenital heart defects, amyloidosis, or parasitic diseases may constitute a source of bleeding. This etiological heterogeneity may, as a result, cause diagnostic difficulties during post-mortem elucidation of hemothorax. It should be borne in mind that hemothorax after low-energy trauma does not exclusively indicate traumatic hemorrhage, hence, the non-traumatic origin of bleeding must be taken into consideration. In this paper, we present a systematic review of the relevant literature enriched by the results of our observations to investigate the etiologies and recommendations for the post-mortem diagnosis of spontaneous hemothorax in an attempt to better delineate the possible medicolegal considerations. It is important that forensic pathologist as well as clinicians are aware of the diseases that could potentially give rise to fatal hemothorax. Copyright © 2013 Elsevier Ireland Ltd.

Nonoperative management of blunt hepatic injuries is highly successful. Complications associated with high-grade injuries, however, have not been well characterized. The purpose of the present study was therefore to define hepatic-related complications and associated treatment modalities in patients undergoing nonoperative management of high-grade blunt hepatic injuries. Three hundred thirty-seven patients from two regional Level I trauma centers with grade 3 to 5 blunt hepatic injuries during a 40-month period were reviewed. Complications and treatment of hepatic-related complications in patients not requiring laparotomy in the first 24 hours were identified. Of 337 patients with a grade 3 to 5 injury, 230 (68%) were managed nonoperatively. There were 37 hepatic-related complications in 25 patients (11%); 63% (5 of 8) of patients with grade 5 injuries developed complications, 21% (19 of 92) of patients with grade 4 injuries, but only 1% (1 of 130) of patients with grade 3 injuries. Complications included bleeding in 13 patients managed by angioembolization (n = 12) and laparotomy (n = 1), liver abscesses in 2 patients managed with computed tomography-guided drainage (n = 2) and subsequent laparotomy (n = 1). In one patient with bleeding, hepatic necrosis followed surgical ligation of the right hepatic artery and required delayed hepatic lobectomy. Sixteen biliary complications were managed with endoscopic retrograde cholangiopancreatography and stenting (n = 7), drainage (n = 5), and laparoscopy (n = 4). Three patients had suspected abdominal sepsis and underwent a negative laparotomy, whereas an additional three patients underwent laparotomy for abdominal compartment syndrome. Nonoperative management of high-grade liver injuries can be safely accomplished. Mortality is low; however, complications in grade 4 and 5 injuries should be anticipated and may require a combination of operative and nonoperative management strategies.

Analytical review of 664 cases of penetrating buttock trauma

PubMed Central

2011-01-01

A comprehensive review of data has not yet been provided as penetrating injury to the buttock is not a common condition accounting for 2-3% of all penetrating injuries. The aim of the study is to provide the as yet lacking analytical review of the literature on penetrating trauma to the buttock, with appraisal of characteristics, features, outcomes, and patterns of major injuries. Based on these results we will provide an algorithm. Using a set of terms we searched the databases Pub Med, EMBASE, Cochran, and CINAHL for articles published in English between 1970 and 2010. We analysed cumulative data from prospective and retrospective studies, and case reports. The literature search revealed 36 relevant articles containing data on 664 patients. There was no grade A evidence found. The injury population mostly consists of young males (95.4%) with a high proportion missile injury (75.9%). Bleeding was found to be the key problem which mostly occurs from internal injury and results in shock in 10%. Overall mortality is 2.9% with significant adverse impact of visceral or vascular injury and shock (P < 0.001). The major injury pattern significantly varies between shot and stab injury with small bowel, colon, or rectum injuries leading in shot wounds, whilst vascular injury leads in stab wounds (P < 0.01). Laparotomy was required in 26.9% of patients. Wound infection, sepsis or multiorgan failure, small bowel fistula, ileus, rebleeding, focal neurologic deficit, and urinary tract infection were the most common complications. Sharp differences in injury pattern endorse an algorithm for differential therapy of penetrating buttock trauma. In conclusion, penetrating buttock trauma should be regarded as a life-threatening injury with impact beyond the pelvis until proven otherwise. PMID:21995834

Limited data are available from the Australian setting regarding bleeding in patients with atrial fibrillation (AF) receiving antithrombotic therapy. We aimed to investigate the incidence of hospital admissions due to bleeding and factors associated with bleeding in patients with AF who received antithrombotic therapy. A retrospective cohort study was conducted involving all patients with AF admitted to the Royal Hobart Hospital, Tasmania, Australia, between January 2011 and July 2015. Bleeding rates were calculated per 100 patient-years (PY) of follow-up, and multivariable modelling was used to identify predictors of bleeding. Of 2202 patients receiving antithrombotic therapy, 113 presented to the hospital with a major or minor bleeding event. These patients were older, had higher stroke and bleeding risk scores and were more often treated with warfarin and multiple antithrombotic therapies than patients who did not experience bleeding. The combined incidence of major and minor bleeding was significantly higher in warfarin- versus direct-acting oral anticoagulants (DOAC)- and antiplatelet-treated patients (4.1 vs 3.0 vs 1.2 per 100 PY, respectively; p = 0.002). Similarly, the rate of major bleeding was higher in patients who received warfarin than in the DOAC and antiplatelet cohorts (2.4 vs 0.4 vs 0.6 per 100 PY, respectively; p = 0.001). In multivariate analysis, increasing age, prior bleeding, warfarin and multiple antithrombotic therapies were independently associated with bleeding. The overall rate of bleeding in this cohort was low relative to similar observational studies. The rate of major bleeding was higher in patients prescribed warfarin compared to DOACs, with a similar rate of major bleeding for DOACs and antiplatelet agents. Our findings suggest potential to strategies to reduce bleeding include using DOACs in preference to warfarin, and avoiding multiple antithrombotic therapies in patients with AF.

Effect of nabumetone and aspirin on colonic mucosal bleeding time.

2001-04-01

The management of patients taking aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) who require colonoscopy remains controversial because of concerns over bleeding after biopsy or polypectomy. To determine whether patients using the NSAID nabumetone, a non-acidic prodrug with mixed activity against cyclooxygenase-1 (COX-1) and COX-2, exhibited prolonged mucosal bleeding times and how this might compare with mucosal bleeding times in patients using aspirin. We assessed triplicate mucosal bleeding times in patients undergoing screening flexible sigmoidoscopy. We compared 90 patients who had taken no aspirin or NSAIDs within the previous 2 weeks, to 60 patients who had received nabumetone 1 g b.d. by mouth for the previous 2 weeks, and 30 patients who had taken 325 mg aspirin daily for the previous 2 weeks. In each case, the investigator performing the study was blinded to the patient's medication. Mucosal bleeding times did not differ significantly among control or nabumetone-using patients. However, the patients receiving aspirin exhibited significant prolongation. Mucosal bleeding time correlated statistically significantly, but weakly, with skin bleeding time. Nabumetone does not appear to prolong mucosal bleeding time after mucosal pinch biopsy, and skin bleeding time does not reliably screen for prolonged mucosal bleeding time.

To explore the method and experience in correction of pectus carinatum with minimally invasive procedure. Between June 2010 and January 2014, 30 patients with pectus carinatum were corrected by minimally invasive procedure. There were 21 boys and 9 girls whose average age was 13 years and 2 months (range, from 8 years and 10 months to 18 years and 9 months), including 24 cases of first operation, 2 recurrence after traditional pectus carinatum correction, and 4 cases secondary to median thoracotomy. Thirty patients had symmetric and asymmetric mild pectus carinatum. The operation was performed successfully in all patients, and no severe complication occurred. The operation time was 42-95 minutes (mean, 70 minutes). The bleeding volume during operation was 4-30 mL (mean, 10 mL). The time from operation to discharge was 6-10 days (mean, 7 days). The average time of follow-up was 25 months (range, 9-54 months). All surgical wound healed primarily with no infection. The X-ray films showed slight pneumothorax in 7 cases, and it was absorbed after 1 month without treatment. Loosening of internal fixation was found in 1 patient because of trauma at 6 months, and operation was performed again. The bar was removed at 2 years in 21 patients. The patients had good thoracic contour and normal activity. Minimally invasive procedure for correction of pectus carinatum is safe and will get satisfactory effect in maintaining thoracic contour. It has also less trauma and shorter operation time.

To study the relationship between clinicopathological characteristics, prognosis and gastrointestinal bleeding in primary gastrointestinal stromal tumors (GIST). The clinicopathological and follow-up data of 200 patients with gastrointestinal stromal tumors treated in our hospital from April 2008 to December 2014 were retrospectively reviewed. The correlation of gastrointestinal bleeding with gastrointestinal stromal tumor clinicopathological characteristics and prognosis were analyzed. The 200 GIST patients were divided into two groups according to the bleeding in the digestive tract, including 57 gastrointestinal bleeding patients and 143 non-bleeding patients. The mean tumor diameter was 6.5 cm (range 1.8-22 cm) in the bleeding group and 2.5 cm (range 0.4-18 cm) in the non-bleeding group (P<0.05). Of the 57 bleeding patients, 31 located in the stomach, 25 in the small intestine, and one had colorectal bleeding. Fifty patients had mitotic index (MI) ≤ 5/50 HPF, other 6 patients ranged between 5 and 10/50 HPF and one patient had MI >10/50 HPF. Six GIST patients were complicated with tumor rapture. But in the non-bleeding group, 125 patients had gastric GIST, 8 in the small intestine, one colorectum, and 9 had esophageal or other GIST. 141 patients had MI ≤5/50 HPF, 1 patients ranged between 5 and 10/50 HPF and one patient had MI >10/50 HPF. Only 1 GIST patients was complicated with tumor rapture. The gastrointestinal bleeding was closely associated with tumor size, mitotic index, tumor location, risk classifications, tumor rapture and tumor recurrence (P<0.05 for all). The 3-year and 5-year survival rates of the 200 patients were 96.5% and 86.8%, respectively. 16 patients developed recurrence or metastasis, and 11 died of GIST. The 5-year survival rate of patients with gastrointestinal bleeding was 76.2%, significantly lower than that of patients without gastrointestinal bleeding (91.6%, P<0.05). GIST patients complicated with gastrointestinal bleeding have poor prognosis, and attention should be paid to stratifying patients for therapy.

Thrombosis and inflammation are intricately linked in several major clinical disorders, including disseminated intravascular coagulation and acute ischemic events. The damage-associated molecular pattern molecule high-mobility group box 1 (HMGB1) is upregulated by activated platelets in multiple inflammatory diseases; however, the contribution of platelet-derived HMGB1 in thrombosis remains unexplored. Here, we generated transgenic mice with platelet-specific ablation of HMGB1 and determined that platelet-derived HMGB1 is a critical mediator of thrombosis. Mice lacking HMGB1 in platelets exhibited increased bleeding times as well as reduced thrombus formation, platelet aggregation, inflammation, and organ damage during experimental trauma/hemorrhagic shock. Platelets were the major source of HMGB1 within thrombi. In trauma patients, HMGB1 expression on the surface of circulating platelets was markedly upregulated. Moreover, evaluation of isolated platelets revealed that HMGB1 is critical for regulating platelet activation, granule secretion, adhesion, and spreading. These effects were mediated via TLR4- and MyD88-dependent recruitment of platelet guanylyl cyclase (GC) toward the plasma membrane, followed by MyD88/GC complex formation and activation of the cGMP-dependent protein kinase I (cGKI). Thus, we establish platelet-derived HMGB1 as an important mediator of thrombosis and identify a HMGB1-driven link between MyD88 and GC/cGKI in platelets. Additionally, these findings suggest a potential therapeutic target for patients sustaining trauma and other inflammatory disorders associated with abnormal coagulation.

Post-traumatic pseudoaneurysm of the common hepatic artery with duodenal fistula

PubMed Central

Matsumoto, Cal; Wayne, Michael; Schwartz, Myron E

2002-01-01

Background Post-traumatic pseudoaneurysm of the hepatic artery is rare, especially after blunt abdominal trauma; an even more rare occurrence is enteric fistulisation. Case outline A 29-year-old man was admitted with an acute episode of upper gastrointestinal bleeding three months after blunt abdominal trauma and was found to have an hepatic artery pseudoaneurysm with duodenal fistula. Surgical treatment was by ligature of the artery and duodenal closure with omental patch. Discussion There is one previous case report of hepatic artery pseudoaneurysm as a delayed complication of blunt abdominal trauma. The presence of a haematoma in the hepatoduodenal ligament after blunt trauma should raise the suspicion of hepatic artery injury, and surgical exploration may prevent the subsequent development of pseudoaneurysm. CT scan has become an important instrument both in diagnosis and in surgical planning. PMID:18332952

Although propofol-based sedation can be used during emergency endoscopy for upper gastrointestinal bleeding (UGIB), there is a potential risk of sedation-related adverse events, especially in patients with variceal bleeding. We compared adverse events related to propofol-based sedation during emergency endoscopy between patients with non-variceal and variceal bleeding. Clinical records of patients who underwent emergency endoscopy for UGIB under sedation were reviewed. Adverse events, including shock, hypoxia, and paradoxical reaction, were compared between the non-variceal and variceal bleeding groups. Of 703 endoscopies, 539 and 164 were performed for non-variceal and variceal bleeding, respectively. Shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding (12.2 vs. 3.5%, P < 0.001). All patients except one recovered from shock after normal saline hydration, and emergency endoscopy could be finished without interruption in most cases. The incidence of hypoxia and paradoxical reaction did not differ based on the source of bleeding (non-variceal bleeding vs. variceal bleeding: hypoxia, 3.5 vs. 1.8%, P = 0.275; paradoxical reaction interfering with the procedure, 4.1 vs. 5.5%, P = 0.442). Although shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding, most cases could be controlled without procedure interruption. Paradoxical reaction, rather than shock or hypoxia, was the most common cause of procedure interruption in patients with variceal bleeding, but the rate did not differ between patients with non-variceal and variceal bleeding.

Tranexamic acid--an old drug still going strong and making a revival.

Experience with tranexamic acid, an indirect fibrinolytic inhibitor, started as soon as it was released from Shosuke Okamoto's lab in the early 1960s. It was first prescribed to females with heavy menstrual blood loss and to patients with hereditary bleeding disorders. Soon the indications were widened to elective surgery because of its blood saving effects. Contraindications are few, most important is ongoing venous or arterial thrombosis and allergy to tranexamic acid, and the doses has to be reduced in renal insufficiency. In randomized controlled trials, however, patients with other risk factors are excluded as well (patients with history of cardiovascular disease, thromboembolism, bleeding diathesis, renal failure with creatinine >250μmol/L, pregnancy, and patients on treatment with anticoagulants). Recent meta-analyses of several randomized controlled trials in orthopedic arthroplasty have shown that tranexamic acid reduces peri- and postoperative blood loss, blood transfusion requirements and reoperations caused by bleedings. In general, the preoperative dose was 10-15mg/kg i.v. (or 1g), followed or not, by one or two doses, some as continuous infusion i.v. To validate relationship between dose and effect more data are needed. No evidence was found of increased thromboembolic accidents or other adverse events in the patients on tranexamic acid compared to the control groups. In major cardiac surgery tranexamic acid has been used in a large number of controlled trials with various dosing schemes in which the highest dosages seem to be associated with neurotoxicity; therefore a maximum total dose of 100mg/kg especially in patients over 50years of age is recommended by ISMICS (International Society for Minimally Invasive Cardiothoracic Surgery). Other indications for tranexamic acid are reviewed here as well. In recent years the extensive trial in severe trauma with massive bleedings using tranexamic acid was presented, CRASH-2 (Clinical Randomisation of an Antifibrinolytic in Significant Haemorrhage) comprising more than 20,000 patients. It showed that the survival was increased when tranexamic acid was given early after the accident compared to placebo; further studies are taking place is this field to get more information. Of utmost importance is the ongoing WOMAN (World Maternal Antifibrinolytic) a randomized, double-blind, placebo controlled trial among 15,000 with clinical diagnosis of postpartum haemorrhage bearing in mind that each year a large number of women in low and middle income countries, die from causes related to childbirth. In summary, we consider tranexamic acid is a drug of great value to reduce almost any kind of bleeding, it is cheap and convenient to use and has principally few contraindications. It may be added, that tranexamic acid is included in the WHOs list of essential medicines. Copyright © 2014. Published by Elsevier Ltd.

Endoscopic methods (gastroscopy and colonoscopy) are considered fundamental for the diagnosis of gastrointestinal bleeding. In recent years, multidetector computed tomography (MDCT) has also gained importance in diagnosing gastrointestinal bleeding, particularly in hemodynamically unstable patients and in cases with suspected lower gastrointestinal tract bleeding. CT can detect both the source and the cause of active gastrointestinal bleeding, thereby expediting treatment initiation. The study group consisted of 16 patients with clinical symptoms of gastrointestinal bleeding in whom features of active bleeding were observed on CT. In all patients, bleeding was verified by means of other methods such as endoscopic examinations, endovascular procedures, or surgery. The bleeding source was identified on CT in all 16 patients. In 14 cases (87.5%), bleeding was confirmed by other methods. CT is an efficient, fast, and readily available tool for detecting the location of acute gastrointestinal bleeding.

A group of 133 patients treated for bleeding peptic ulcer in our Department, is reviewed. Within several hours of admission, all patients underwent upper gastrointestinal tract gastroscopy and obliteration of the bleeding ulcer. Bleeding gastric ulcers were found in 41 patients, and duodenal ulcers in 92 patients. Patients were classified according to the Forrest scale: IA – 11 patients, IB – 49 patients, IIA – 35 patients, lIB – 40 patients. In 126 (94.7%) patients the bleeding was stopped, and 7 required urgent surgery: 3 patients with gastric ulcer underwent gastrectomy, and 4 with duodenal ulcer – truncal vagotomy with pyloroplasty and had the bleeding site underpinned. Fifty-five patients underwent elective surgery: gastrectomy and vagotomy (18 patients with gastric ulcer), highly selective vagotomy (25 patients with duodenal ulcer) and truncal vagotomy and pyloroplasty (12 patients with duodenal ulcer). None of the patients was observed to have recurrent bleeding. PMID:18493453

Autoerythrocyte sensitization syndrome (Gardner Diamond syndrome or GDS) is a rare syndrome characterized by painful and spontaneous purpura commonly affecting adult women, and is mostly associated with psychiatric illness. Diagnosis is mainly based on clinical presentation, exclusion of other simulating diseases, and psychiatric evaluation. Only few cases have been reported till date. We report five cases of spontaneous purpura with a normal investigation profile, except for iron deficiency anemia in 1 patient, of which three had associated underlying psychiatric illness. Autoerythrocyte sensitization test was positive in all our cases. Patients presenting with painful bruises without significant medical history such as underlying bleeding disorder or drug history or history of trauma should be considered for autoerythrocyte sensitization syndrome, and managed accordingly. The present study is a case series of patients with characteristic features of autoerythrocyte sensitization syndrome, considering the rarity of the reports on its clinical spectra. PMID:29644197

A headache not to be sneezed at.

Garry, D; Forrest-Hay, A

2009-05-01

A 32-year-old male patient presented to the emergency department (ED) complaining of a headache and vertigo precipitated by sneezing. He had a recent history of neck trauma. Examination revealed horizontal nystagmus and a gait that veered to the left, exacerbated by heel to toe walking. A diagnosis of vertebral artery dissection (VAD) was suspected. A bleed was ruled out in the ED by computerised tomography, after which the patient was loaded with aspirin. The diagnosis was confirmed by magnetic resonance imaging and magnetic resonance angiography. Although optimal treatment for VAD is unknown, the Cervical Artery Dissection in Stroke Study (CADISS) is an ongoing randomised multicentre prospective study comparing antiplatelet therapy with anticoagulation for patients with both carotid artery dissection and VAD. Headache is a very common presentation to the ED and a full neurological examination is essential if rarer causes are not to be missed.

Although the possibility of bleeding during anticoagulant treatment may limit patients from taking part in physical activity, the association between physical activity and anticoagulation-related bleeding is uncertain. To determine whether physical activity is associated with bleeding in elderly patients taking anticoagulants. In a prospective multicenter cohort study of 988 patients aged ≥ 65 years receiving anticoagulants for venous thromboembolism, we assessed patients' self-reported physical activity level. The primary outcome was the time to a first major bleeding, defined as fatal bleeding, symptomatic bleeding in a critical site, or bleeding causing a fall in hemoglobin or leading to transfusions. The secondary outcome was the time to a first clinically relevant non-major bleeding. We examined the association between physical activity level and time to a first bleeding by using competing risk regression, accounting for death as a competing event. We adjusted for known bleeding risk factors and anticoagulation as a time-varying covariate. During a mean follow-up of 22 months, patients with a low, moderate, and high physical activity level had an incidence of major bleeding of 11.6, 6.3, and 3.1 events per 100 patient-years and an incidence of clinically relevant non-major bleeding of 14.0, 10.3, and 7.7 events per 100 patient-years, respectively. A high physical activity level was significantly associated with a lower risk of major bleeding (adjusted sub-hazard ratio 0.40, 95% confidence interval 0.22-0.72). There was no association between physical activity and non-major bleeding. A high level of physical activity is associated with a decreased risk of major bleeding in elderly patients receiving anticoagulant therapy. © 2014 International Society on Thrombosis and Haemostasis.

Earlier Endpoints Are Required for Hemorrhagic Shock Trials among Severely Injured Patients

Background Choosing the appropriate endpoint for a trauma hemorrhage control trial can determine the likelihood of its success. Recent Phase 3 trials and observational studies have used 24-hour and/or 30-day all-cause mortality as the primary endpoint and some have not used exception from informed consent (EFIC), resulting in multiple failed trials. Five recent high-quality prospective studies among 4,064 hemorrhaging trauma patients provide new evidence to support earlier primary endpoints. Methods The goal of this project was to determine the optimal endpoint for hemorrhage control trials using existing literature and new analyses of previously published data. Results Recent studies among bleeding trauma patients show that hemorrhagic deaths occur rapidly, at a high rate, and in a consistent pattern. Early preventable deaths among trauma patients are largely due to hemorrhage and the median time to hemorrhagic death from admission is 2.0-2.6 hours. Approximately 85% of hemorrhagic deaths occur within 6 hours. The hourly mortality rate due to traumatic injury decreases rapidly after enrollment from 4.6% per hour at 1 hour post-enrollment to 1% per hour at 6 hours to <0.1% per hour by 9 hours and thereafter. Early primary endpoints (within 6 hours) have critically important benefits for hemorrhage control trials, including being congruent with the median time to hemorrhagic death, biologic plausibility, and enabling the use of all-cause mortality, which is definitive and objective. Conclusions Primary endpoints should be congruent with the timing of the disease process. Therefore, if a resuscitation/hemorrhage control intervention is under study, a primary endpoint of all-cause mortality evaluated within the first 6 hours is appropriate. Before choosing the timing of the primary endpoint for a large multicenter trial, we recommend performing a Phase 2 trial under EFIC to better understand the effects of the hemorrhage control intervention and distribution of time to death. When early primary endpoints are used, patients should be monitored for multiple subsequent secondary safety endpoints, including 24 hour and 30 day all-cause mortality as well as the customary safety endpoints.

Mihalik, Jason P; Myers, Joseph B; Sell, Timothy C; Anish, Eric J

2005-01-01

Objective: To present the case of a 17-year-old male soccer goalkeeper who sustained maxillofacial fractures and dental trauma after being struck in the face by an opponent's knee. Background: Because of the nature of the sport and a lack of protective headgear, soccer players are at risk for sustaining maxillofacial trauma. Facial injuries can complicate the routine management of on-field medical emergencies often encountered by certified athletic trainers. The appropriate management of maxillofacial trauma on the playing field may help to reduce both the immediate and long-term morbidity and mortality associated with these injuries. Differential Diagnosis: Lacerated superior labial artery, lacerated upper lip, dental fractures, maxillofacial fractures, orbital blowout fracture, closed head injury, cervical spine injury, cerebrovascular accident. Treatment: The athlete received immediate on-field medical care and was subsequently transported to the hospital, where diagnostic testing was performed and further treatment was provided. Hospital inpatient management included dental and plastic surgery. After discharge from the hospital, the athlete underwent several additional dental procedures, including gingival surgery and nonsurgical endodontic treatments. The fractures were followed closely to assure that adequate healing had occurred. The athlete did not return to soccer. Uniqueness: Certified athletic trainers need to be prepared for on-field medical emergencies. Bleeding associated with maxillofacial trauma can complicate basic medical interventions such as airway maintenance. Inappropriate on-field management may result in unnecessary morbidity and mortality for the injured athlete. Therefore, immediate recognition of the severity of the injury is needed in order to institute appropriate airway-management strategies. Conclusions: It is sometimes necessary to consider nonstandard methods of airway management in order to first address heavy bleeding that may be associated with facial trauma. Achieving hemostasis is essential in order to prevent potentially life-threatening complications related to hemorrhage, such as airway obstruction and hypovolemic shock. PMID:15970958

The efficacy and safety of physiotherapeutic prophylaxis for venous thromboembolism in critically ill patients with heparin contraindication remains unclear. In the present study it was hypothesized that physiotherapy prophylaxis with intermittent pneumatic compression (IPC) would be safe and effective for patients unable to receive low-molecular-weight heparin (LMWH). In addition, this study investigated whether a combined therapy of IPC with LMWH would be more effective for the prophylaxis of deep vein thrombosis (DVT) in critical patients. A total of 500 patients were divided into four groups according to the prophylaxis of DVT. The IPC group consisted of 95 patients with heparin contraindication that received IPC treatment; the LMWH group consisted of 185 patients that received an LMWH injection; the LMWH + IPC group consisted of 75 patients that received IPC treatment and LMWH injection; and the control group consisted of 145 patients that received no IPC treatment or injection of LMWH. Each patient was evaluated clinically for development of DVT and the diagnosis was confirmed by Doppler study. Venous thromboembolism was a common complication among the trauma patients with severe injuries. Patients responded positively to the treatment used in the intervention groups. Patients exhibited an improved response to LMWH + ICP compared with IPC or LMWH alone, while no significant difference was detected between the IPC and LMWH groups. These results were applicable to patients that had a Wells score of ≥3; however, no significant differences in DVT incidence were observed among the patients who had a Wells score of <3. In this observational study, LMWH + ICP appeared to be more effective than either treatment alone in treating critically ill trauma patients with severe injuries that are at high risk for VTE and bleeding simultaneously.

Hepatic artery pseudoaneurysm (HAP) is an uncommon but serious complication of blunt trauma abdomen which can be managed by non-surgical interventional methods. We describe the case of a young boy with blunt trauma abdomen having a large hepatic laceration associated with two pseudoaneurysms of the hepatic artery branches. Both these HAPs were successfully managed by percutaneous injection of cyanoacrylate glue under sonographic guidance. A major surgery was thus averted. A brief review of the etiology, diagnosis and management of HAP including the present case is discussed.

The authors present their experience in the endoscopic laser photocoagulation of bleeding peptic ulcer. From 1991 to June 1995, 203 patients admitted for UGI bleeding from peptic ulcer have been treated by this method. The source of bleeding was confirmed by endoscopy. The patients were divided into two groups: actively bleeding peptic ulcer (group IA and IB according to Forrest's classification) and ulcer with stigmata of recent bleeding (group IIA/IIB). The former group consisted of 106 patients, among whom over 40 percent (45 patients) presented signs of hypovolemic shock on admission. Nd:YAG laser (Surgical Laser Technologies) was used in a continuous mode with a contact (8 - 20 watts) or non-contact (over 50 watts) method of coagulation. In actively bleeding patients photocoagulation resulted in stopping the hemorrhage in 95 (90%). Recurrent bleeding occurred in 16 cases; in 9 of them it was stopped by repeated photocoagulation. In this group 18 patients required surgical intervention. The mortality was of 10.3% (11 patients). In 97 patients with recent bleeding stigmata photocoagulation provoked heavy hemorrhage in 3 (in 2 cases stopped by prolonged coagulation). In 9 of the remaining 94 patients recurrent bleeding occurred. Nine patients required surgical intervention. Mortality in this group was of 6%.

Dental extractions challenge the body's haemostatic mechanism. Postoperative bleeding from dental extraction can be prolonged, or even life threatening in patients with inherited bleeding disorders. Pre- and postoperative clotting factor replacements or systemic desmopressin (ddAVP) have been advocated at our institution to prevent bleeding complications in these patients. This study aimed to assess the postoperative bleeding rate in patients with inherited bleeding disorders that underwent dental extractions at our institution between 2003 and 2012. Patients with inherited bleeding disorders such as haemophilia A, haemophilia B, and von Willebrand's disease were included. Retrospective chart review was conducted. The result showed 53 extraction events occurred in 45 patients over the 10-year period. Ten out of 53 extraction events (18.9%) had postoperative bleeding requiring further factor replacement or ddAVP. Postoperative bleeding in one patient with mild haemophilia A was complicated by the development of inhibitors. Type and severity of bleeding disorder, bone removal, and use of a local haemostatic agent did not have any significant effect on postoperative bleeding. Despite the use of perioperative factors and desmopressin, the postoperative bleeding rates remain high for patients with inherited bleeding disorders. More studies are required to assess the safety and effectiveness of using local haemostatic control to achieve haemostasis following extractions. Crown Copyright © 2017. Published by Elsevier Ltd.

Von Willebrand's disease: case report and review of literature.

Von Willebrand Disease (VWD) is the most common human inherited bleeding disorder due to a defect of Von Willebrand Factor (VWF), which a glycoprotein crucial for platelet adhesion to the subendothelium after vascular injury. VWD include quantitative defects of VWF, either partial (type 1 with VWF levels < 50 IU/dL) or virtually total (type 3 with undetectable VWF levels) and also qualitative defects of VWF (type 2 variants with discrepant antigenic and functional VWF levels). The most bleeding forms of VWD usually do not concern type 1 patients with the mildest VWF defects (VWF levels between 30 and 50IU/dL). Von willebrand factor is a complex multimeric protein with two functions: it forms a bridge between the platelets and areas of vascular damage and it binds to and stabilizes factor VIII, which is necessary for the clotting cascade. By taking a clinical history of bleeding (mucocutaneous bleeding symptoms suggestive of a primary haemostatic disorder, a quantitative or qualitative abnormality of VWF is possible) it is important to think about VWD and to make the appropriate diagnosis. If the VWD is suspected diagnostic tests should include an activated partial thromboplastin time, bleeding time, factor VIII: C Ristocetin cofactor and vWF antigen. Additional testing of ristocetin induced plattlet adhesion (RIPA) the multimeric structure and collagen binding test and genanalysis allow diagnosing the different types of von. Willebrand Disease. The treatment of choice in mild forms is the synthetic agent desmopressin. In patients with severe type 1, type 2B, 2N and type 3 or in people who do not response to desmopressin, the appropriate treatment is a factor VIII concentrate that is rich of VWF. We report a case of infant in 27-month-old boy who had been referred due to haemorrhagic shock. His birth histories, his familie's social history and developmental milestones were unremarkable. He was born at full term with no antenatal or perinatal complications. Prior to the symptoms, the child was on a normal diet and was thriving appropriately. The child presented one days before his admission trauma to the inner face of the lower lip that caused an external acute bleeding loss. The laboratory data showed unfortunately, the most severe form of Von Willebrand's Disease; Type 3. The management was based on erythrocyte and fresh-frozen plasma (FFP) transfusions with administration of factor VII with good evolution.

Penetrating abdominal trauma.

The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed by procedures in the ED. Only lifesaving procedures necessary to prevent further deterioration should temporarily delay sending a patient to a waiting surgical team. Stable patients can be further evaluated in the ED. Those with stab wounds to the abdomen, flank, and selected cases of back injuries should undergo LWE. Those with negative LWE can be discharged after appropriate wound care and patient education. Patients with equivocal or positive LWE should undergo DPL. Patients with tangential gunshot wounds and possible type 2 shotgun injuries can undergo DPL. Table 8 lists the recommended thresholds for DPL. Patients with positive DPL should undergo exploration.(ABSTRACT TRUNCATED AT 400 WORDS)

Prasugrel is a third-generation thienopyridine that achieves potent platelet inhibition with less pharmacological variability than other thienopyridines. However, clinical experience suggests that prasugrel may be associated with a higher risk of de novo and recurrent bleeding events compared with clopidogrel in Japanese patients undergoing percutaneous coronary intervention (PCI). In this review, we evaluate the risk of bleeding in Japanese patients treated with prasugrel at the doses (loading/maintenance doses: 20/3.75 mg) adjusted for Japanese patients, evaluate the risk factors for bleeding in Japanese patients, and examine whether patients with a bleeding event are at increased risk of recurrent bleeding. This review covers published data and new analyses of the PRASFIT (PRASugrel compared with clopidogrel For Japanese patIenTs) trials of patients undergoing PCI for acute coronary syndrome or elective reasons. The bleeding risk with prasugrel was similar to that observed with the standard dose of clopidogrel (300/75 mg), including when bleeding events were re-classified using the Bleeding Academic Research Consortium criteria. The pharmacodynamics of prasugrel was not associated with the risk of bleeding events. The main risk factors for bleeding events were female sex, low body weight, advanced age, and presence of diabetes mellitus. Use of a radial puncture site was associated with a lower risk of bleeding during PCI than a femoral puncture site. Finally, the frequency and severity of recurrent bleeding events during continued treatment were similar between prasugrel and clopidogrel. In summary, this review provides important insights into the risk and types of bleeding events in prasugrel-treated patients.Trial registration numbers: JapicCTI-101339 and JapicCTI-111550.

Acute on chronic gastrointestinal bleeding: a unique clinical entity.

Rockey, Don C; Hafemeister, Adam C; Reisch, Joan S

Gastrointestinal bleeding is defined in temporal-spatial terms-as acute or chronic, and/or by its location in the gastrointestinal tract. Here, we define a distinct type of bleeding, which we have coined 'acute on chronic' gastrointestinal bleeding. We prospectively identified all patients who underwent endoscopic evaluation for any form of gastrointestinal bleeding at a University Hospital. Acute on chronic bleeding was defined as the presence of new symptoms or signs of acute bleeding in the setting of chronic bleeding, documented as iron deficiency anemia. Bleeding lesions were categorized using previously established criteria. We identified a total of 776, 254, and 430 patients with acute, chronic, or acute on chronic bleeding, respectively. In patients with acute on chronic gastrointestinal bleeding, lesions were most commonly identified in esophagus (28%), colon and rectum (27%), and stomach (21%) (p<0.0001 vs locations for acute or chronic bleeding). In those specifically with acute on chronic upper gastrointestinal bleeding (n=260), bleeding was most commonly due to portal hypertensive lesions, identified in 47% of subjects compared with 29% of acute and 25% of chronic bleeders, (p<0.001). In all patients with acute on chronic bleeding, 30-day mortality was less than that after acute bleeding alone (2% (10/430) vs 7% (54/776), respectively, p<0.001). Acute on chronic gastrointestinal bleeding is common, and in patients with upper gastrointestinal bleeding was most often a result of portal hypertensive upper gastrointestinal tract pathology. Reduced mortality in patients with acute on chronic gastrointestinal bleeding compared with those with acute bleeding raises the possibility of an adaptive response.

Extracorporeal membrane oxygenation (ECMO) is associated with a significant risk of bleeding and thrombosis. Despite high rates of bleeding and bleeding-related mortality in patients on ECMO, there is little evidence available to guide clinicians in the management of ECMO-associated bleeding. We report the use of aminocaproic acid in four patients with bleeding on ECMO and a review of the literature. High D-dimer levels and low fibrinogen levels suggested that an antifibrinolytic agent may be effective as an adjunct to control bleeding. After aminocaproic acid administration, bleeding was controlled in each patient as evidenced by clinical and laboratory parameters. One patient suffered a cardiac arrest and care was withdrawn. In patients on ECMO with evidence of fibrinolysis, aminocaproic acid may be an effective option to control bleeding and to stabilize clot formation. Copyright © 2016 Elsevier Inc.

Retrospective analysis of patients over 18 years of age who underwent endoscopy for acute upper gastrointestinal bleeding or anaemia (haemoglobin<100 g/l) with proved source of blood losses in upper gastrointestinal tract during a hospital stay in 2013 (from January to June). We included 111 patients of average age 69±15 years, men 60%. Nonvariceal bleeding accounted for 90% of the cases. None of the patients with variceal bleeding (10% of patients) took antiplatelet or anticoagulation therapy. There were 100 patients with nonvariceal bleeding of average age 70±15, 61% men. With the symptoms of acute bleeding (hematemesis, melena) presented in 73% of patients. The most frequent cause of bleeding was gastric and duodenal ulcer (54%). 32% of patients with nonvariceal bleeding had antiplatelets, 19% anticoagulants and 10% used nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors or corticosteroids. 30-days mortality of patients with nonvariceal bleeding was 11%, annual mortality was 23%. There was no significant difference in mortality, blood transfusion requirements or surgical intervention between the patients with antithrombotic agents and without them. 25% of patients (8 patients) using acetylsalicylic acid did not fulfil the indication for this treatment. Among the patients examined by endoscopy for symptomatic nonvariceal bleeding and/or anaemia (haemoglobin<100 g/l) significantly higher portions of patients are taking antiplatelet rather than anticoagulation therapy. This may be caused by greater use of these drugs in the population, but on the other hand it may reflect an association with greater risk of gastrointestinal bleeding. With regard to that, it is alarming, that there still exists a nonnegligible percentage of patients taking acetylsalicylic acid even though they do not meet the indication for the prescription according to the guidelines.

Bleeding complications accompanying coronary revascularization are associated with increased mortality; however, few data are available on subsequent bleeding risk. We used administrative data to assess the incidence of late bleeding events in patients with acute coronary syndrome (ACS) according to treatment allocation. The cohort and bleeding events were identified through the Canadian Institute for Health Information discharge abstract database. Crude and adjusted odds ratios (ORs) were calculated for index and postindex admission bleeding up to 1 year after discharge. Of 31,941 patients hospitalized with ACS, 7681 (32.4%) patients were treated with medication alone, 3728 (15.2%) underwent angiography without intervention, and 13,075 (53.4%) underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). The overall incidence of readmission with bleeding based on administrative codes was low (3.8% for medically treated patients, 2.8% for patients who underwent angiography alone, 2.6% for patients who underwent CABG, and 1.8% for patients who underwent PCI; P < 0.0001). Bleeding codes were mainly gastrointestinal bleeding (52%), but 7.8% were intracranial episodes of bleeding. Patients who received PCI had significantly lower odds of late bleeding compared with medically treated patients (OR, 0.76; 95% CI, 0.62-0.94). Late bleeding during the first year after ACS was associated with mortality (OR, 4.96; 95% CI, 2.47-9.93). Patients who underwent revascularization procedures had a relatively low risk for late bleeding events after a hospitalization for ACS. Late bleeding events were associated with an increased risk of death. Copyright © 2017 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

Management of Patients with Acute Lower Gastrointestinal Bleeding

Strate, Lisa L.; Gralnek, Ian M.

2016-01-01

This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal hemorrhage. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based upon clinical parameters should be performed to help distinguish patients at high and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper GI bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 hours of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, CT angiography, angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation, and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. NSAID use should be avoided in patients with a history of acute lower GI bleeding particularly if secondary to diverticulosis or angioectasia. In patients with established cardiovascular disease who require aspirin (secondary prophylaxis), aspirin should not be discontinued. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis and the risk of a thromboembolic event. Surgery for the prevention of recurrent lower gastrointestinal bleeding should be individualized and the source of bleeding should be carefully localized prior to resection. PMID:26925883

Abdominal blunt trauma is the main cause of death in people younger than 40 years old. The liver injury still represents a challenging problem. Isolated hepatic injury is rare and it occurs more frequentely in polytraumatizated patients and causes massive haemoperitoneum. The Authors report a case of a 83 years-old woman admitted to Emergency Department for syncope due to an active bleeding arising from a rupture of a right hepatic lobe unsuspected tumor. The computer tomography (CT) scans showed a clear pattern of liver laceration of the VI segment with contrast enhancement spreading in the surrounding tissues, and detected a multifocal hepatocarcinoma located in the VI, VII and VIII segments. Patient's haemodinamically unstable conditions suggested an urgent laparotomy. An accurate perihepatic packing with sterile-drape were successfully employed to control liver hemorrage. Temporary abdominal closure, followed by hepatic arteriography and the right hepatic artery embolization, completed the damage control. Re-exploration laparotomy after 72 hours confirmed the definitive haemostasis and the pack removal was performed without complications. CT plays a leading role in the diagnosis of liver damage. The patient's haemodynamic status is the principal criterion determining conservative or operative therapy in blunt liver injury. The early perihepatic packing followed by artheriographic embolization to stop liver hemorrhage showed efficacy and safety for the patient. The packing performed with sterile-drape is able to avoid removal complications and 72 hours timing for the pack removal is effective to avoid re-bleeding.

Previously, we reported on the use of emergency tourniquets to stop bleeding in war casualties, but virtually all the data were from adults. Because no pediatric-specific cohort of casualties receiving emergency tourniquets existed, we aimed to fill knowledge gaps on the care and outcomes of this group by surveying data from a trauma registry to refine device designs and clinical training. A retrospective review of data from a trauma registry yielded an observational cohort of 88 pediatric casualties at US military hospitals in theater on whom tourniquets were used from May 17, 2003, to December 25, 2009. Of the 88 casualties in the study group, 72 were male and 16 were female patients. Ages averaged 11 years (median, 11 years; range, 4-17 years). There were 7 dead and 81 survivor outcomes for a trauma survival rate of 93%. Survivor and dead casualties were similar in all independent variables measured except hospital stay duration (median, 5 days and 1 day, respectively). Six casualties (7%) had neither extremity nor external injury in that they had no lesion indicating tourniquet use. The survival rate of the present study's casualties is similar to that of 3 recent large nonpediatric-specific studies. Although current emergency tourniquets were ostensibly designed for modern adult soldiers, tourniquet makers, perhaps unknowingly, produced tourniquets that fit children. The rate of unindicated tourniquets, 7%, implied that potential users need better diagnostic training. Level 4; case series, therapeutic study.

Correlation Between Findings of Multislice Helical Computed Tomography (CT), Endoscopic Examinations, Endovascular Procedures, and Surgery in Patients with Symptoms of Acute Gastrointestinal Bleeding

2017-01-01

Summary Background Endoscopic methods (gastroscopy and colonoscopy) are considered fundamental for the diagnosis of gastrointestinal bleeding. In recent years, multidetector computed tomography (MDCT) has also gained importance in diagnosing gastrointestinal bleeding, particularly in hemodynamically unstable patients and in cases with suspected lower gastrointestinal tract bleeding. CT can detect both the source and the cause of active gastrointestinal bleeding, thereby expediting treatment initiation. Material/Methods The study group consisted of 16 patients with clinical symptoms of gastrointestinal bleeding in whom features of active bleeding were observed on CT. In all patients, bleeding was verified by means of other methods such as endoscopic examinations, endovascular procedures, or surgery. Results The bleeding source was identified on CT in all 16 patients. In 14 cases (87.5%), bleeding was confirmed by other methods. Conclusions CT is an efficient, fast, and readily available tool for detecting the location of acute gastrointestinal bleeding. PMID:29662594

Novel Use of Thalidomide in Recurrent Gastrointestinal Tract Bleeding in Patients with Left Ventricular Assist Devices: A Case Series.

Bleeding is an important and common complication of left ventricular assist devices (LVADs). One of the common causes of gastrointestinal bleeding is arteriovenous malformations. However, the source of bleeding is often hard to identify. Thalidomide is efficacious in treatment of gastrointestinal (GI) bleeding in non-LVAD patients. We report our experience of the use of thalidomide in the treatment of GI bleeding in four patients with LVAD. Four patients who had recurrent GI bleeding from May 2009 to December 2014 were started on thalidomide. All of them responded to treatment and had no further gastrointestinal bleeding while on thalidomide. One patient developed constipation, requiring thalidomide to be stopped. Another patient developed symptomatic neuropathy, that resolved with reduction of dosage. Thalidomide appears safe and efficacious in LVAD patients with recurrent gastrointestinal bleeding.

Blood autotransfusion outcomes compared with Ringer lactate infusion in dogs with hemorrhagic shock induced by controlled bleeding.

PubMed

Safaei, Mansour; Takami, Hassan Mousavi

2011-10-01

The most common cause of shock in the surgical or trauma patient is hemorrhage. Crystalloid solutions and blood transfusion are the mainstays of treatment of hemorrhagic shock. Considering the disadvantages of allogeneic blood transfusion, such as risk of transmission of infectious diseases, and access and maintenance limitations, treatment of shock with autologous blood seems to be a decent solution. Autologous blood accumulated in body cavities in traumatic bleeding (such hemothorax), and bloodshed in operation field during open heart or vascular surgeries, and similar situations, can be utilized again. In this study, autotransfusion effects compared with crystalloid fluid in the treatment of hemorrhagic shock was investigated. After induction of hemorrhagic shock in dogs by Wiggers type controlled bleeding, treating them in a group with autologous blood and another group with Ringer lactate were performed, and the results of treatment were studied. There was no mortality in both treatment approaches. Immediately after treatment, crystalloid positive effects such as renormalized vital signs and appropriate consciousness were more noticeable than autotransfusion, while twenty-four hours after, the desired effects of autologous blood were more pronounced like decreased metabolic acidosis and improvement of diuresis. Crystalloid during the first hours after treatment of hemorrhagic shock may be better than autologous blood as preferred treatment, while autotransfusion showed its benefits some hours after. This finding can be used to develop better strategies for treatment of hemorrhagic shock.

In the last few years, the number of anticoagulated patients has significantly increased and, as a consequence, so have hemorrhagic complications due to this therapy. We analyzed gastrointestinal (GI) bleeding because it is the most frequent type of major bleeding in these patients, and we hypothesized that they would have lesions responsible for GI bleeding regardless of the intensity of anticoagulation, although excessively anticoagulated patients would have more serious hemorrhages. To study the characteristics of anticoagulated patients with GI bleeding and the relationship between the degree of anticoagulation and a finding of causative lesions and bleeding severity. We prospectively studied 96 patients, all anticoagulated with acenocoumarol and consecutively admitted to hospital between 01/01/2003 and 09/30/2005 because of acute GI bleeding. We excluded patients with severe liver disease, as well as nine patients with incomplete details. The incidence of GI bleeding requiring hospitalization was 19.6 cases/100,000 inhabitants-year. In 90% of patients, we found a causative (85% of upper GI bleeding and 50% of lower GI bleeding) or potentially causative lesion, and 30% of them required endoscopic treatment, without differences depending on the intensity of anticoagulation. No relationship was found between the type of lesions observed and the degree of anticoagulation in these patients. Patients who received more intense anticoagulation therapy had more severe hemorrhages (23% of patients with an INR ≥4 had a life-threatening bleed versus only 4% of patients with INR <4). We found an incidence of 20 severe GI bleeding episodes in anticoagulated patients per 100,000 inhabitants-year, with no difference in localization or in the frequency of causative lesions depending on the intensity of anticoagulation. Patients receiving more intense anticoagulation had more severe GI bleeding episodes. Copyright © 2013 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

Reduced thrombin formation and excessive fibrinolysis are associated with bleeding complications in patients with dengue fever: a case–control study comparing dengue fever patients with and without bleeding manifestations

PubMed Central

2013-01-01

Background Dengue cases have been classified according to disease severity into dengue fever (DF) and dengue hemorrhagic fever (DHF). Although DF is considered a non-severe manifestation of dengue, it has been recently demonstrated that DF represents a heterogeneous group of patients with varied clinical complications and grades of severity. Particularly, bleeding complications, commonly associated to DHF, can be detected in half of the patients with DF. Although a frequent complication, the causes of bleedings in DF have not been fully addressed. Thus, the aim of this study was to perform a comprehensive evaluation of possible pathophysiological mechanisms that could contribute to the bleeding tendency observed in patients with DF. Methods This is a case–control study that enrolled adults with DF without bleeding and adults with DF and bleeding complications during the defervescence period. Healthy controls were also included. Peripheral blood counts, inflammatory, fibrinolysis and endothelial cell activation markers, and thrombin generation were evaluated in patients and controls. Results We included 33 adults with DF without complications, 26 adults with DF and bleeding and 67 healthy controls. Bleeding episodes were mild in 15 (57.6%) and moderate in 11 (42.4%) patients, 8 (30.7%) patients had bleedings in multiple sites. Patients with DF and bleedings had lower platelet counts than DF without bleeding (median = 19,500 vs. 203,500/mm3, P < 0,0001). Levels of TNF-α, thrombomodulin and VWF were significantly increased in the two dengue groups than in healthy controls, but similar between patients with and without bleedings. Plasma levels of tPA and D-dimer were significantly increased in patients with bleedings (median tPA levels were 4.5, 5.2, 11.7 ng/ml, P < 0.0001 and median D-dimer levels were 515.5, 1028 and 1927 ng/ml, P < 0.0001). The thrombin generation test showed that patients with bleeding complications had reduced thrombin formation (total thrombin generated were 3753.4 in controls, 3367.5 in non-bleeding and 2274.5nM in bleeding patients, P < 0.002). Conclusions DF can manifest with spontaneous bleedings, which are associated with specific coagulation and fibrinolysis profiles that are not significantly present in DF without this complication. Particularly, thrombocytopenia, excessive fibrinolysis and reduced thrombin formation may contribute to the bleeding manifestations in DF. PMID:23890510

AIM: To prospectively assess the hemostatic efficacy of the endoscopic topical use of ankaferd blood stopper (ABS) in active non-variceal upper gastrointestinal system (GIS) bleeding. METHODS: Endoscopy was performed on 220 patients under suspiciency of GIS bleeding. Patients with active non-variceal upper gastrointestinal bleeding (NVUGIB) with a spurting or oozing type were included. Firstly, 8-10 cc of isotonic saline was sprayed to bleeding lesions. Then, 8 cc of ABS was applied on lesions in which bleeding continued after isotonic saline application. The other endoscopic therapeutic methods were applied on the lesions in which the bleeding did not stop after ABS. RESULTS: Twenty-seven patients had an active NVUGIB with a spurting or oozing type and 193 patients were excluded from the study since they did not have non-variceal active bleeding. 8 cc of ABS was sprayed on to the lesions of 26 patients whose bleeding continued after isotonic saline and in 19 of them, bleeding stopped after ABS. Other endoscopic treatment methods were applied to the remaining patients and the bleeding was stopped with these interventions in 6 of 7 patients. CONCLUSION: ABS is an effective method on NVUGIB, particularly on young patients with no coagulopathy. ABS may be considered as part of a combination treatment with other endoscopic methods.

The overall incidence, causes, and treatment of posttransplant gastrointestinal bleeding, have been previously described. In this study, we examined the causes and treatment of postoperative gastrointestinal bleeding after orthotopic liver transplant. Clinical data of 335 patients who underwent an orthotopic liver transplant at our institution between September 2001 and December 2012 were analyzed retrospectively. The diagnosis and treatment of postoperative gastrointestinal bleeding after an orthotopic liver transplant were reviewed. Gastrointestinal bleeding occurred in 13 patients (3.8%) after an orthotopic liver transplant. Five patients (38.4%) were adult and 8 patients (61.6%) were pediatric. The sites of the bleeding were Roux-en-Y anastomosis bleeding in 5 cases, peptic ulcer in 3 cases, erosive gastritis in 3 cases, gastric and esophageal varices in 1 case, and hemobilia in 1 case. These 13 patients with gastrointestinal bleeding were managed with conservative treatment, endoscopic treatment, radiologic interventional embolism, or exploratory laparotomy. No patients died because of gastro--intestinal bleeding. During follow-up, 4 patients died because of sepsis and 1 patient died of recurrence of hepatocellular carcinoma. Gastrointestinal bleeding after liver transplant and its incidence, causes, and treatment are not well-described in the literature. Diagnosis and management of gastrointestinal bleeding requires a multidisciplinary approach involving surgeons, hepatologists, advanced and experienced endoscopists, and interventional radiologists.

Computational Model for Hyperfibrinolytic Onset of Acute Traumatic Coagulopathy.

2018-04-19

The onset of acute traumatic coagulopathy in trauma patients exacerbates hemorrhaging and dramatically increases mortality. The disease is characterized by increased localized bleeding, and the mechanism for its onset is not yet known. We propose that the fibrinolytic response, specifically the release of tissue-plasminogen activator (t-PA), within vessels of different sizes leads to a variable susceptibility to local coagulopathy through hyperfibrinolysis which can explain many of the clinical observations in the early stages from severely injured coagulopathic patients. We use a partial differential equation model to examine the consequences of vessel geometry and extent of injury on fibrinolysis profiles. In addition, we simulate the efficacy of tranexamic acid treatment on coagulopathy initiated through endothelial t-PA release, and are able to reproduce the time-sensitive nature of the efficacy of this treatment as observed in clinical studies.

Gastrointestinal Bleeding Due to Gastrointestinal Tract Malignancy: Natural History, Management, and Outcomes.

Schatz, Richard A; Rockey, Don C

2017-02-01

Gastrointestinal (GI) tumor bleeding can vary from occult bleeding to massive hemorrhage and can be the presenting sign of malignancy. Our primary aims were to: (1) characterize the natural history, treatment, and outcomes in patients with GI tumor bleeding and (2) compare and contrast bleeding in upper GI (UGI)/small bowel (SB) and lower GI malignancies. Patients with endoscopically confirmed tumor bleeding were identified through search of consecutive electronic medical records: Bleeding was determined by the presence of melena, hematochezia, hematemesis, or fecal occult blood. Comprehensive clinical and management data were abstracted. A total of 354 patients with GI tumors were identified: 71 had tumor bleeding (42 UGI/SB and 29 colonic). GI bleeding was the initial presenting symptom of malignancy in 55/71 (77%) of patients; 26/71 patients had widely metastatic disease at presentation. Further, 15 of 26 patients with metastatic disease presented with GI bleeding. Visible bleeding was present in 14/42 (33%) and 4/29 (14%) of UGI/SB and colonic tumors, respectively. Endoscopic hemostasis was attempted in 10 patients, and although initial control was successful in all, bleeding recurred in all of these patients. The most common endoscopic lesion was clean-based tumor ulceration. Overall mortality at 1 year was 57% for esophageal/gastric, 14% for SB, and 33% for colonic tumors. When patients with GI malignancy present with GI bleeding, it is often the index symptom. Initial endoscopic hemostasis is often successful, but rebleeding is typical. Esophageal and gastric tumors carry the poorest prognosis, with a high 1-year mortality rate.

Two hundred patients affected by liver cirrhosis and oesophageal varices were studied in 9 Gastrointestinal Units in Lombardy (Northern Italy) in order to assess factors possibly related to variceal bleeding. Only patients without any previous episode of gastrointestinal bleeding were included in the prospective evaluation. For each patient demographic data, aetiology of cirrhosis, various clinical and biochemical parameters able to group patients into the three Child-Pugh Classes, endoscopic items for calculation of Beppu's and of NIEC prognostic scores were recorded on computerized cards. Patients were regularly interviewed every three months for one year and underwent an upper gastrointestinal endoscopy at enrollment, after six months and in case of bleeding. Within the twelve-month follow-up period, 29 out of the 200 patients (14%) bled and 52 out of 200 died (26%). In 16 of the 52 patients who died (59% of bleeding patients) death was directly related to gastrointestinal bleeding. Bleeding from oesophageal varices was endoscopically proven in 19/29 patients, in another 9 bleeding was classified as from unknown source and in one patient a bleeding gastric ulcer was diagnosed. Univariate analysis of all the recorded clinical, biochemical and endoscopic parameters, performed by Chi-square method and Fisher exact test showed that the presence of RWM (p < 0.001) was the only factor significantly associated to variceal bleeding within one year. Relationship between size of varices and bleeding was very close to the statistical significance but did not achieve it (p = 0.058).

Nano- and micro-materials in the treatment of internal bleeding and uncontrolled hemorrhage.

Gaston, Elizabeth; Fraser, John F; Xu, Zhi Ping; Ta, Hang T

2018-02-01

Internal bleeding is defined as the loss of blood that occurs inside of a body cavity. After a traumatic injury, hemorrhage accounts for over 35% of pre-hospital deaths and 40% of deaths within the first 24 hours. Coagulopathy, a disorder in which the blood is not able to properly form clots, typically develops after traumatic injury and results in a higher rate of mortality. The current methods to treat internal bleeding and coagulopathy are inadequate due to the requirement of extensive medical equipment that is typically not available at the site of injury. To discover a potential route for future research, several current and novel treatment methods have been reviewed and analyzed. The aim of investigating different potential treatment options is to expand available knowledge, while also call attention to the importance of research in the field of treatment for internal bleeding and hemorrhage due to trauma.

Quebec platelet disorder: update on pathogenesis, diagnosis, and treatment.

PubMed

Blavignac, Jessica; Bunimov, Natalia; Rivard, Georges E; Hayward, Catherine P M

2011-09-01

Quebec platelet disorder (QPD) is an autosomal dominant bleeding disorder associated with reduced platelet counts and a unique gain-of-function defect in fibrinolysis due to increased expression and storage of urokinase plasminogen activator (uPA) by megakaryocytes. QPD increases risks for bleeding and its key clinical feature is delayed-onset bleeding, following surgery, dental procedures or trauma, which responds only to treatment with fibrinolytic inhibitors. The genetic cause of the disorder is a tandem duplication mutation of the uPA gene, PLAU, which upregulates uPA expression in megakaryocytes by an unknown mechanism. The increased platelet stores of uPA trigger plasmin-mediated degradation of QPD α-granule proteins. The gain-of-function defect in fibrinolysis is thought to be central to the pathogenesis of QPD bleeding as the activation of QPD platelets leads to release of uPA from α-granules and accelerated clot lysis. The purpose of this review is to summarize current knowledge on QPD pathogenesis and the recommended approaches to QPD diagnosis and treatment. Thieme Medical Publishers.

In girls who present with vaginal trauma, sexual abuse is often the primary diagnosis. The differential diagnosis must include patterns and the mechanism of injury that differentiate accidental injuries from inflicted trauma. A 7-year-old prepubertal girl presented to the emergency department with genital bleeding after a serious accidental impaling injury from inline skating. After rapid abduction of the legs and a fall onto the blade of an inline skate this child incurred an impaling genital injury consistent with an accidental mechanism. The dramatic genital injuries when repaired healed with almost imperceptible residual evidence of previous trauma. To our knowledge, this case report represents the first in the medical literature of an impaling vaginal trauma from an inline skate and describes its clinical and surgical management.

We aimed to assess the association between arterial hypertension and bleeding in patients undergoing percutaneous coronary intervention (PCI). The impact of arterial hypertension on bleeding risk of patients with coronary artery disease undergoing PCI is unknown. This study included 14,180 patients who underwent PCI. Bleeding was defined using the Bleeding Academic Research Consortium (BARC) criteria. Arterial hypertension was defined as treatment with antihypertensive drugs or a systolic blood pressure >140 mm Hg and/or diastolic blood pressure value >90 mm Hg documented on at least 2 occasions. The primary outcome was bleeding rate within 30 days of PCI. Overall, 11,066 patients (78.0%) had arterial hypertension. Bleeding events occurred in 1,232 patients with arterial hypertension and 278 patients without arterial hypertension (11.1% vs 8.9%; odds ratio [OR] = 1.28, 95% confidence interval [CI] 1.11-1.46, P < 0.001). Access-site bleeding occurred in 730 patients with arterial hypertension and 175 patients without arterial hypertension (6.6% vs 5.6%: OR = 1.19 [1.01-1.41], P = 0.049). Non-access-site bleeding occurred in 502 patients with and 103 patients without arterial hypertension (4.5% vs 3.3%; OR = 1.39 [1.12-1.72], P = 0.003). After adjustment, arterial hypertension was significantly associated with any bleeding (adjusted OR = 1.41 [1.19-1.67], P < 0.001), access-site bleeding (adjusted OR = 1.36 [1.10-1.68], P = 0.005) and non-access-site bleeding (adjusted OR = 1.42 [1.09-1.83], P = 0.008). A history of arterial hypertension increased the risk of non-access-site bleeding (P = 0.002), whereas systolic blood pressure at the time of PCI increased the risk of access site bleeding (P = 0.018). Arterial hypertension is associated with increased risk of bleeding during PCI procedures. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

The aim of this study was to evaluate the clinical utility of the new bleeding criteria, proposed by the Bleeding Academic Research Consortium (BARC), compared with the old criteria for determining the action of physicians in contact with bleeding events, after percutaneous coronary intervention (PCI). The BARC criteria were independently associated with an increased risk of 1-year mortality after PCI, and provided a predictive value, in regard to 1-year mortality. The standardized bleeding definitions will be expected to help the physician to correctly analyze the bleeding events, to select an optimal treatment, and to objectively compare the results of multiple trials and registries. All the patients undergoing PCI from June to September 2012 were prospectively enrolled. Patients who experienced a bleeding event were further classified, based on three different bleeding severity criteria: BARC, Thrombolysis In Myocardial Infarction (TIMI), and Global Use of Strategies To Open coronary arteries (GUSTO). The primary outcome was the occurrence of bleeding events requiring interruption of antiplatelet therapy (IAT) by physicians. A total of 376 consecutive patients were included in this study. Total bleeding events occurred in 46 patients (12.2%). BARC type ≥2 bleeding occurred in 30 patients (8.0%); however, TIMI major or minor bleeding, and GUSTO moderate or severe bleeding occurred in 6 (1.6%) and 11 patients (2.9%), respectively. Of the 46 patients, 28 (60.9% of patients) required IAT. On receiver-operating characteristic curve analysis, bleeding defined BARC type ≥2 effectively predicted IAT, with a sensitivity of 89.3%, and a specificity of 98.5% (p<0.001), compared with TIMI (sensitivity, 21.4%; specificity, 100%; p<0.001), and GUSTO (sensitivity, 39.3%; specificity, 100%; p<0.001). Compared with TIMI and GUSTO, the BARC definition may be a more useful tool for the detection of bleeding with clinical relevance, for patients undergoing PCI.

While modifiable bleeding risks should be addressed in all patients with atrial fibrillation (AF), use of a bleeding risk score enables clinicians to 'flag up' those at risk of bleeding for more regular patient contact reviews. We compared a risk assessment strategy for major bleeding and intracranial hemorrhage (ICH) based on modifiable bleeding risk factors (referred to as a 'MBR factors' score) against established bleeding risk stratification scores (HEMORR 2 HAGES, HAS-BLED, ATRIA, ORBIT). A nationwide cohort study of 40,450 AF patients who received warfarin for stroke prevention was performed. The clinical endpoints included ICH and major bleeding. Bleeding scores were compared using receiver operating characteristic (ROC) curves (areas under the ROC curves [AUCs], or c-index) and the net reclassification index (NRI). During a follow up of 4.60±3.62years, 1581 (3.91%) patients sustained ICH and 6889 (17.03%) patients sustained major bleeding events. All tested bleeding risk scores at baseline were higher in those sustaining major bleeds. When compared to no ICH, patients sustaining ICH had higher baseline HEMORR 2 HAGES (p=0.003), HAS-BLED (p<0.001) and MBR factors score (p=0.013) but not ATRIA and ORBIT scores. When HAS-BLED was compared to other bleeding scores, c-indexes were significantly higher compared to MBR factors (p<0.001) and ORBIT (p=0.05) scores for major bleeding. C-indexes for the MBR factors score was significantly lower compared to all other scores (De long test, all p<0.001). When NRI was performed, HAS-BLED outperformed all other bleeding risk scores for major bleeding (all p<0.001). C-indexes for ATRIA and ORBIT scores suggested no significant prediction for ICH. All contemporary bleeding risk scores had modest predictive value for predicting major bleeding but the best predictive value and NRI was found for the HAS-BLED score. Simply depending on modifiable bleeding risk factors had suboptimal predictive value for the prediction of major bleeding in AF patients, when compared to the HAS-BLED score.

ACG Clinical Guideline: Diagnosis and Management of Small Bowel Bleeding.

Gerson, Lauren B; Fidler, Jeff L; Cave, David R; Leighton, Jonathan A

2015-09-01

Bleeding from the small intestine remains a relatively uncommon event, accounting for ~5-10% of all patients presenting with gastrointestinal (GI) bleeding. Given advances in small bowel imaging with video capsule endoscopy (VCE), deep enteroscopy, and radiographic imaging, the cause of bleeding in the small bowel can now be identified in most patients. The term small bowel bleeding is therefore proposed as a replacement for the previous classification of obscure GI bleeding (OGIB). We recommend that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract. A source of small bowel bleeding should be considered in patients with GI bleeding after performance of a normal upper and lower endoscopic examination. Second-look examinations using upper endoscopy, push enteroscopy, and/or colonoscopy can be performed if indicated before small bowel evaluation. VCE should be considered a first-line procedure for small bowel investigation. Any method of deep enteroscopy can be used when endoscopic evaluation and therapy are required. VCE should be performed before deep enteroscopy if there is no contraindication. Computed tomographic enterography should be performed in patients with suspected obstruction before VCE or after negative VCE examinations. When there is acute overt hemorrhage in the unstable patient, angiography should be performed emergently. In patients with occult hemorrhage or stable patients with active overt bleeding, multiphasic computed tomography should be performed after VCE or CTE to identify the source of bleeding and to guide further management. If a source of bleeding is identified in the small bowel that is associated with significant ongoing anemia and/or active bleeding, the patient should be managed with endoscopic therapy. Conservative management is recommended for patients without a source found after small bowel investigation, whereas repeat diagnostic investigations are recommended for patients with initial negative small bowel evaluations and ongoing overt or occult bleeding.

The S 2 TOP-BLEED score may help to identify patients at high risk of bleeding on antiplatelet drugs after a transient ischemic attack or ischemic stroke. The score was derived on trial populations, and its performance in a real-world setting is unknown. We aimed to externally validate the S 2 TOP-BLEED score for major bleeding in a population-based cohort and to compare its performance with other risk scores for bleeding. We studied risk of bleeding in 2072 patients with a transient ischemic attack or ischemic stroke on antiplatelet agents in the population-based OXVASC (Oxford Vascular Study) according to 3 scores: S 2 TOP-BLEED, REACH, and Intracranial-B 2 LEED 3 S. Performance was assessed with C statistics and calibration plots. During 8302 patient-years of follow-up, 117 patients had a major bleed. The S 2 TOP-BLEED score showed a C statistic of 0.69 (95% confidence interval [CI], 0.64-0.73) and accurate calibration for 3-year risk of major bleeding. The S 2 TOP-BLEED score was much more predictive of fatal bleeding than nonmajor bleeding (C statistics 0.77; 95% CI, 0.69-0.85 and 0.50; 95% CI, 0.44-0.58). The REACH score had a C statistic of 0.63 (95% CI, 0.58-0.69) for major bleeding and the Intracranial-B 2 LEED 3 S score a C statistic of 0.60 (95% CI, 0.51-0.70) for intracranial bleeding. The ratio of ischemic events versus bleeds decreased across risk groups of bleeding from 6.6:1 in the low-risk group to 1.8:1 in the high-risk group. The S 2 TOP-BLEED score shows modest performance in a population-based cohort of patients with a transient ischemic attack or ischemic stroke. Although bleeding risks were associated with risks of ischemic events, risk stratification may still be useful to identify a subgroup of patients at particularly high risk of bleeding, in whom preventive measures are indicated. © 2018 The Authors.

Gastrointestinal (GI) bleeding is a common complication of oral anticoagulation. This study evaluated GI bleeding in patients who received at least 1 dose of the study drug in the on-treatment arm of the ROCKET AF (Rivaroxaban Once-daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation) trial. The primary outcome was adjudicated GI bleeding reported from first to last drug dose + 2 days. Multivariable modeling was performed with pre-specified candidate predictors. Of 14,236 patients, 684 experienced GI bleeding during follow-up. These patients were older (median age 75 years vs. 73 years) and less often female. GI bleeding events occurred in the upper GI tract (48%), lower GI tract (23%), and rectum (29%) without differences between treatment arms. There was a significantly higher rate of major or nonmajor clinical GI bleeding in rivaroxaban- versus warfarin-treated patients (3.61 events/100 patient-years vs. 2.60 events/100 patient-years; hazard ratio: 1.42; 95% confidence interval: 1.22 to 1.66). Severe GI bleeding rates were similar between treatment arms (0.47 events/100 patient-years vs. 0.41 events/100 patient-years; p = 0.39; 0.01 events/100 patient-years vs. 0.04 events/100 patient-years; p = 0.15, respectively), and fatal GI bleeding events were rare (0.01 events/100 patient-years vs. 0.04 events/100 patient-years; 1 fatal events vs. 5 fatal events total). Independent clinical factors most strongly associated with GI bleeding were baseline anemia, history of GI bleeding, and long-term aspirin use. In the ROCKET AF trial, rivaroxaban increased GI bleeding compared with warfarin. The absolute fatality rate from GI bleeding was low and similar in both treatment arms. Our results further illustrate the need for minimizing modifiable risk factors for GI bleeding in patients on oral anticoagulation. Copyright © 2015 American College of Cardiology Foundation.

BACKGROUND: The present clinical trial was designed to compare the results of bilateral inguinal hernia repair between patients who underwent the conventional Stoppa technique and laparoscopic total extraperitoneal repair (LTE) with a single mesh and without staple fixation. PATIENTS AND METHODS: This controlled, randomised clinical trial was conducted at General Surgery and Trauma of the Clinics Hospital, Medical School, the University of São Paulo between September 2010 and February 2011. Totally, 50 male patients, with a bilateral inguinal hernia, older than 25 years were considered eligible for the study. The following parameters were analysed during the early post-operative period: (1) The intensity of surgical trauma, operation time, C-reactive protein (CRP) levels, white blood cell count, bleeding and pain intensity; (2) quality of life assessment; and (3) post-operative complications. RESULTS: LTE procedure was longer than the Stoppa procedure (134.6 min ± 38.3 vs. 90.6 min ± 41.3; P < 0.05). The levels of CRP were higher in the Stoppa group (P < 0.05) but the number of leucocytes, haematocrit, and haemoglobin were similar between the groups (P > 0.05). There was no difference in pain during the 1st and 7th post-operative, physical functioning, physical limitation, the impact of pain on daily activities, and the Carolinas Comfort Scale during the 7th and 15th post-operative (P > 0.05). Complications occurred in 88% of Stoppa group (22 patients) and 64% in LTE group (16 patients) (P < 0.05). CONCLUSION: The comparative study between the Stoppa and LTE approaches for the bilateral inguinal hernia repair demonstrated that: (1) The LTE approach showed less surgical trauma despite the longer operation time; (2) Quality of life during the early post-operative period were similar; and (3) Complication rates were higher in the Stoppa group.

The influence of gastrointestinal bleeding on clinical presentation and outcomes of patients with acute ischemic stroke remains controversial. We investigate the effect of gastrointestinal bleeding on the outcomes of patients with acute, first-ever ischemic stroke. We enrolled 934 patients with acute, first-ever ischemic stroke and followed up them for 3years. Patients were divided into 2 groups according to the presence or absence of gastrointestinal bleeding during acute stroke stage. Clinical presentation, stroke risk factors, laboratory data, co-morbidities, and outcomes were recorded. Seventy-six (8.1%) patients had gastrointestinal bleeding at admission. The prevalence of old age, atrial fibrillation, and previous transient ischemic attack was higher in patients with gastrointestinal bleeding (P<0.001, P=0.038, and P=0.018, respectively). Total anterior circulation syndrome occurred more frequently among patients with gastrointestinal bleeding (P<0.001). The mean length of acute ward stay, initial impaired consciousness, and stroke in evolution were higher in patients with gastrointestinal bleeding (P<0.001, P<0.001, and P<0.001, respectively). The occurrence of pneumonia and dependent functional outcome were higher in patients with gastrointestinal bleeding (P<0.001 and P<0.001, respectively). A multivariate Cox regression analysis revealed that gastrointestinal bleeding is a significant risk factor for 3-year all-cause mortality (hazard ratio=2.76; 95% confidence interval=1.61-4.72; P<0.001). In conclusion, gastrointestinal bleeding is associated with increased risk of 3-year mortality in patients with acute, first-ever ischemic stroke. Prophylactic therapies for gastrointestinal bleeding might improve ischemic stroke outcome. Copyright © 2017 Elsevier Ltd. All rights reserved.

Acute bleeding after bone marrow transplantation (BMT) was investigated in 1,402 patients receiving transplants at Johns Hopkins Hospital between January 1, 1986 and June 30, 1995. Bleeding categorization was based on daily scores of intensity used by the blood transfusion service. Moderate and severe episodes were analyzed for bleeding sites. Analysis of the cause of death and the interval of the bleeding episode to outcome endpoints was recorded. Survival estimates were computed for 1,353 BMT patients. The overall incidence was 34%. Minor bleeding was seen in 10.6%, moderate bleeding was seen in 11.3%, and severe bleeding was seen in 12% of all patients. Fourteen percent of patients had moderate or severe gastrointestinal hemorrhage, 6.4% had moderate or severe hemorrhagic cystitis, 2.8% had pulmonary hemorrhage, and 2% had intracranial hemorrhage. Sixty-one percent had 1 bleeding site and 34.4% had more than 1 site. Moderate and severe bleeding was more prevalent in allogeneic (31%) and unrelated patients (62.5%) compared with autologous patients (18.5%). Significant distribution of incidence was found among the different diagnoses, but not by disease status in acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, Hodgkin's disease, and non-Hodgkin's lymphoma. Bleeding was associated with significantly reduced survival in allogeneic, autologous, and unrelated BMT and in each disease category except multiple myeloma. Survival was correlated with the bleeding intensity, bleeding site, and the number of sites. Although close temporal association was evident to mortality, bleeding was recorded as the cause of death in only the minority of cases compared with other toxicities after BMT (graft-versus-host disease, infections, and preparative regimen toxicity). Acute bleeding is a common complication after BMT that is profoundly associated with morbidity and mortality. Although bleeding was not a direct cause of death in the majority of cases, it has a potential prognostic implication as a predictor of poor outcome in clinical assessment of patients after BMT.

Essentials Data on bleeding-related causes of death in non-severe hemophilia A (HA) patients are scarce. Such data may provide new insights into areas of care that can be improved. Non-severe HA patients have an increased risk of dying from intracranial bleeding. This demonstrates the need for specialized care for non-severe HA patients. Background Non-severe hemophilia (factor VIII concentration [FVIII:C] of 2-40 IU dL -1 ) is characterized by a milder bleeding phenotype than severe hemophilia A. However, some patients with non-severe hemophilia A suffer from severe bleeding complications that may result in death. Data on bleeding-related causes of death, such as fatal intracranial bleeding, in non-severe patients are scarce. Such data may provide new insights into areas of care that can be improved. Aims To describe mortality rates, risk factors and comorbidities associated with fatal intracranial bleeding in non-severe hemophilia A patients. Methods We analyzed data from the INSIGHT study, an international cohort study of all non-severe hemophilia A patients treated with FVIII concentrates during the observation period between 1980 and 2010 in 34 participating centers across Europe and Australia. Clinical data and vital status were collected from 2709 patients. We report the standardized mortality rate for patients who suffered from fatal intracranial bleeding, using a general European male population as a control population. Results Twelve per cent of the 148 deceased patients in our cohort of 2709 patients died from intracranial bleeding. The mortality rate between 1996 and 2010 for all ages was 3.5-fold higher than that in the general population (95% confidence interval [CI] 2.0-5.8). Patients who died from intracranial bleeding mostly presented with mild hemophilia without clear comorbidities. Conclusion Non-severe hemophilia A patients have an increased risk of dying from intracranial bleeding in comparison with the general population. This demonstrates the need for specialized care for non-severe hemophilia A patients. © 2017 International Society on Thrombosis and Haemostasis.

A Blown Pupil and Intracranial Hemorrhage in a 4-Week-Old: A Case of Delayed Onset Vitamin K Deficiency Bleeding, a Rare "Can't Miss" Diagnosis.

PubMed

Enz, Ryley; Anderson, Robert S

Infants are at risk for vitamin K deficiency bleeding (VKDB) because of limited stores of vitamin K (VK) at birth and a low concentration of VK in human breast milk. Therefore, the administration of intramuscular (IM) VK at birth has been recommended since 1961 in the United States. Infants who do not receive IM VK and who are exclusively breast-fed are at increased risk for VKDB. While VKDB is rare, a common presentation of late onset VKDB is intracranial hemorrhage. We report the case of a 4-week-old infant who presented to the emergency department with lethargy and a grossly dilated right pupil. The parents denied trauma. A computed tomography scan revealed a right-sided subdural hematoma with midline shift. The infant's international normalized ratio was >10.9 and his prothrombin time PT was >120 seconds. VK was administered and the child was transferred to a tertiary care center for emergent neurosurgery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The difficult part of making this critical diagnosis is considering it. Any bleeding in a newborn without trauma should prompt inquiry regarding neonatal VK administration and a serum prothrombin time level. Fortunately, once the diagnosis is made, therapy in the emergency department can be lifesaving and is familiar to emergency physicians. Treatment parallels usual care for the adult with excess anticoagulation caused by warfarin. Prompt intravenous VK is universally accepted. Studies to support fresh frozen plasma or prothrombin complex concentrate are lacking but make good clinical sense for life-threatening bleeding. Copyright © 2016 Elsevier Inc. All rights reserved.

Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR. A history of upper gastrointestinal bleeding (P<0.001) and lower serum albumin (P=0.004) were independently associated with higher upper gastrointestinal bleeding risk. In patients with CKD who are not receiving dialysis, lower renal function is associated with higher risk for upper gastrointestinal bleeding. The risk is higher in patients with previous upper gastrointestinal bleeding history and low serum albumin. Copyright © 2014 by the American Society of Nephrology.

To report on the post-tonsillectomy bleeding outcomes and factors associated with hemorrhage among children with pre- or post-operatively diagnosed bleeding disorders treated with an institutional protocol. Retrospective cohort study of patients with hematologic disorders who underwent tonsillectomy between 2003 and 2016 and were treated with perioperative desmopressin or factor replacement and/or aminocaproic acid. Postoperative outcomes were compared to controls matched for age, sex, and indication for surgery. Analysis of factors associated with hemorrhage was performed in patients with bleeding disorders using Mann-Whitney U or chi-squared tests. 45 patients with hematologic disorders met inclusion criteria. Platelet dysfunction, including von Willebrand Disease (vWD), was the most common diagnosis (77.8%). Most patients had a preoperative diagnosis of a bleeding disorder and received perioperative hematologic medications (86.7%). Compared to matched controls, patients with hematologic disorders experienced more postoperative bleeding (15.5%; 12 bleeds, 7 patients vs. 1.7%; 1 bleed, 1 patient, p = 0.05) and had longer postoperative stays (1.3 days vs. 0.4 days, p < 0.001). Among the patients with hematologic disorders, patients who experienced a postoperative bleed were significantly more likely to have a factor deficiency (e.g. Hemophilia over vWD) and have a postoperative diagnosis (compared to preoperative diagnosis) for which they did not receive perioperative hematologic medication. Of patients with a postoperative bleed, all those diagnosed postoperatively required at least one surgical intervention to control bleeding compared to 33% of patients with a preoperative diagnosis. A history of post-surgical bleeding, male sex, age at surgery, and pharyngitis as surgical indication were not associated with higher hemorrhage rates in this group. This study suggests a clinically important magnitude of increased bleeding risk in patients with hematologic disease. This risk appears to decrease with the use of an institutional protocol consisting of desmopressin or factor replacement and an antifibrinolytic agent extending through postoperative day 10.

Placement of self-expandable nitinol stents is useful for the treatment of esophageal and upper gastrointestinal (GI) obstruction. However, complications such as stent migration, tumor overgrowth, and bleeding occur. Although stent migration and tumor overgrowth are well documented in previous studies, the occurrence of bleeding has not been fully evaluated. To evaluate the incidence, management strategies, and predictors of bleeding after placement of self-expandable nitinol stents in patients with esophageal and upper GI obstruction. We retrospectively reviewed the medical records and results of computed tomography and endoscopy of 1485 consecutive patients with esophageal and upper GI obstructions who underwent fluoroscopically guided stent placement. Bleeding occurred in 25 of 1485 (1.7%) patients 0 to 348 days after stent placement. Early stent-related bleeding occurred in 10 patients (40%) and angiographic embolization was used for 5/10. Late bleeding occurred in 15 patients (60%) and endoscopic hemostasis was used for 7/15. Twenty-two of 25 (88%) patients with bleeding had received prior radiotherapy and/or chemotherapy. Bleeding is a rare complication after placement of expandable nitinol stents in patients with esophageal and upper GI obstruction, but patients with early bleeding may require embolization for control. Care must be exercised on placing stents in patients who have received prior radiotherapy or chemotherapy. © The Foundation Acta Radiologica 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Not all patients with upper gastrointestinal bleeding (UGIB) require emergency endoscopy. Lactate clearance has been suggested as a parameter for predicting patient outcomes in various critical care settings. This study investigates whether lactate clearance can predict active bleeding in critically ill patients with UGIB. This single-center, retrospective, observational study included critically ill patients with UGIB who met all of the following criteria: admission to the emergency department (ED) from April 2011 to August 2014; had blood samples for lactate evaluation at least twice during the ED stay; and had emergency endoscopy within 6 h of ED presentation. The main outcome was active bleeding detected with emergency endoscopy. Classification and regression tree (CART) analyses were performed using variables associated with active bleeding to derive a prediction rule for active bleeding in critically ill UGIB patients. A total of 154 patients with UGIB were analyzed, and 31.2 % (48/154) had active bleeding. In the univariate analysis, lactate clearance was significantly lower in patients with active bleeding than in those without active bleeding (13 vs. 29 %, P < 0.001). Using the CART analysis, a prediction rule for active bleeding is derived, and includes three variables: lactate clearance; platelet count; and systolic blood pressure at ED presentation. The rule has 97.9 % (95 % CI 90.2-99.6 %) sensitivity with 32.1 % (28.6-32.9 %) specificity. Lactate clearance may be associated with active bleeding in critically ill patients with UGIB, and may be clinically useful as a component of a prediction rule for active bleeding.

This study examined the incidence and risk factors for gastrointestinal (GI) bleeding after spontaneous intracerebral hemorrhage (ICH). The available medical records of patients with ICH admitted from June 2008 to December 2009 for any episode of GI bleeding, possible precipitating factors and administration of ulcer prophylaxis were reviewed. The prevalence of GI bleeding was 26.7%, including 3 cases of severe GI bleeding (0.35%). Patients with GI bleeding had significantly longer hospital stay and higher in-hospital mortality compared with patients without GI bleeding. Multivariate logistic regression analyses showed that age, Glasgow Coma Scale scores, sepsis and ICH volume were independent predictors of GI bleeding. About 63.4% of patients with ICH received stress ulcer prophylaxis. GI bleeding occurred frequently after ICH, but severe events were rare. Age, Glasgow Coma Scale score, sepsis and ICH volume were independent predictors of GI bleeding occurring after ICH.

Bleeding episodes in patients with congenital or acquired bleeding disorders are usually managed with factor concentrates or blood products. However, external and accessible bleeds may effectively be managed with topical hemostasis. After the application of the Hemcon, a Food and Drug Administration-approved chitosan-based hemostatic dressing was used as the "last resort" to successfully control external bleeds in 2 patients with severe bleeding disorders. We describe a single-center experience with this dressing, including its use in pediatric patients as the first mode of therapy. A total of 5 patients (median age 2 y) with severe bleeding disorders were treated with topical chitosan-based dressing for a total of 6 bleeding episodes. The dressing was used either after the failure of extensive systemic therapy or as the first choice of treatment. In 4 of the 6 episodes, bleeding ceased immediately alleviating the need for systemic therapy. There was no rebleeding after the removal of the dressing and no adverse events or local skin reactions were recorded. Hemostatic dressings, such as the chitosan, should be encouraged for the treatment of external/accessible bleeds, especially among the pediatric patients with bleeding tendency.

Direct (non-vitamin-K-dependent) oral anticoagulants (DOAC) are given as an alternative to vitamin K antagonists (VKA) to prevent stroke and embolic disease in patients with atrial fibrillation that is not due to pathology of the heart valves. Fatal hemorrhage is rarer when DOACs are given (nonvalvular atrial fibrillation: odds ratio [OR] 0.68; 95% confidence interval [95% CI: 0.48; 0.96], and venous thromboembolism: OR 0.54; [0.22; 1.32]). 48% of emergency trauma patients need an emergency operation or early surgery. Clotting disturbances elevate the mortality of such patients to 43%, compared to 17% in patients without a clotting disturbance. This underscores the impor tance of the proper, targeted treatment of trauma patients who are aking DOAC. This review is based on articles retrieved by a selective search in PubMed and on a summary of expert opinion and the recommendations of the relevant medical specialty societies. Peak DOAC levels are reached 2-4 hours after the drug is taken. In patients with normal renal and hepatic function, no drug accumulation, and no drug interactions, the plasma level of DOAC 24 hours after administration is generally too low to cause any clinically relevant risk of bleeding. The risk of drug accumulation is higher in patients with renal dysfunction (creatinine clearance [CrCl] of 30 mL/min or less). Dabigatran levels can be estimated from the thrombin time, ecarin clotting time, and diluted thrombin time, while levels of factor Xa inhibitors can be estimated by means of calibrated chromogenic anti-factor Xa activity tests. Routine clotting studies do not reliably reflect the anticoagulant activity of DOAC. Surgery should be postponed, if possible, until at least 24-48 hours after the last dose of DOAC. For patients with mild, non-life threatening hemorrhage, it suffices to discontinue DOAC; for patients with severe hemorrhage, there are special treatment algorithms that should be followed. DOACs in the setting of hemorrhage are a clinical challenge in the traumatological emergency room because of the inadequate validity of the relevant laboratory tests. An emergency antidote is now available only for dabigatran.

The overall impact of post percutaneous coronary intervention (PCI) bleeding on long term prognosis after acute coronary syndromes (ACS) has been established, but it may differ between access and non-access related bleeding events. The impact of antithrombin choice on bleeding may also differ according to the origin of the bleed. We sought to determine the origin of bleeding relative to the access site, its prognostic significance and the respective impact of antithrombin therapy in the EUROMAX trial. We performed a blinded review of the case records of all TIMI major or minor bleeds in the EUROMAX trial and assigned them in one of 2 categories: access site bleeds (ASB), or rest of bleeds (ROB). Incidence of bleeding for each category was assessed according to randomization to antithrombotic treatment. A total of 231 out of 2198 patients suffered a TIMI major/minor bleed (10.5%) and ASB accounted for 48.5%, while ROB for 51.5% of the bleeds. Thirty day mortality was 2.5% (50/1967) for patients without a bleed, 2.7% (3/112, p=0.76 vs. no bleed) for patients with ASB, and 10.9% (13/119, p<0.0001 vs. no bleed) for ROB patients. The use of bivalirudin reduced both ASB and ROB with relative risk reductions of 34% and 46% respectively. In contemporary primary PCI, bleeding originates with equal frequency either at or away from the access site. Access site bleeds were not associated with an excess in 30day mortality, but the rest of the bleeds were. Bivalirudin is associated with a lower risk of bleeding irrespective of origin.

Combined anticoagulant and aspirin therapy is associated with increased bleeding risk in patients with atrial fibrillation, but the bleeding risk of combined use of anticoagulant and nonsteroidal anti-inflammatory drugs (NSAIDs) is poorly documented. To estimate the bleeding risk of combined anticoagulant (rivaroxaban or enoxaparin-vitamin K antagonist [VKA]) and NSAID or aspirin therapy in patients with venous thromboembolism. Prospective analysis of observational data from the EINSTEIN deep vein thrombosis and pulmonary embolism clinical trials comparing rivaroxaban with enoxaparin-VKA treatment, trials performed in hospitals and clinics in 8246 patients enrolled from 2007 to 2009. Bleeding event rates during exposure to NSAID and aspirin therapy were compared to time without exposure. Days of NSAID or aspirin use and nonuse, clinically relevant bleeding event and major bleeding event rates by patient-years, and hazard ratios. During NSAID-anticoagulant concomitant treatment, clinically relevant bleeding occurred with an event rate of 37.5 per 100 patient-years vs 16.6 per 100 patient-years during anticoagulant use only (hazard ratio [HR], 1.77 [95% CI, 1.46-2.14]). Major bleeding during NSAID-anticoagulant treatment occurred with an event rate of 6.5 per 100 patient-years, compared to 2.0 per 100 patient-years during nonuse (HR, 2.37 [95% CI, 1.51-3.75]). For aspirin-anticoagulant concomitant treatment, clinically relevant bleeding occurred with an event rate of 36.6 per 100 patient-years, compared to 16.9 per 100 patient-years during aspirin nonuse (HR, 1.70 [95% CI, 1.38-2.11]). Major bleeding in aspirin-anticoagulant-treated patients occurred with an event rate of 4.8 per 100 patient-years, compared to 2.2 per 100 patient-years during aspirin nonuse (HR, 1.50 [95% CI, 0.86-2.62]). Increases in risk for clinically relevant and major bleeding were similar for rivaroxaban and enoxaparin-VKA anticoagulation regimens. Among patients with venous thromboembolism receiving anticoagulant therapy, concomitant use of an NSAID or aspirin is associated with an increased risk of clinically relevant and major bleeding.

Gastrointestinal (GI) bleeding is one of the most common complications after continuous-flow left ventricular assist device implantation. More than one third of patients with incident bleed go on to develop recurrent GI bleeding. Octreotide, a somatostatin analog, is proposed to reduce the risk of recurrent GI bleeding in this population. This multicenter, retrospective analysis evaluated 51 continuous-flow left ventricular assist device patients who received secondary prophylaxis with octreotide after their index GI bleed from 2009 to 2015. All patients had a hospitalization for GI bleed and received octreotide after discharge. Patient demographics, medical and medication history, and clinical characteristics of patients who rebled after receiving octreotide were compared with non-rebleeders. These data were also compared with matched historical control patients previously enrolled in the HMII (HeartMate II) clinical trials, none of whom received octreotide, to provide a context for the bleeding rates. Twelve patients (24%) who received secondary octreotide prophylaxis developed another GI bleed, whereas 39 (76%) did not. There were similar intergroup demographics; however, significantly more bleeders had a previous GI bleeding history before left ventricular assist device placement (33% versus 5%; P =0.02) and greater frequency of angiodysplasia confirmed during endoscopy (58% versus 23%; P =0.03). Fewer patients in this study experienced a recurrent GI bleed compared with a matched historical control group that did not receive octreotide (24% versus 43%; P =0.04). Patients with continuous-flow left ventricular assist device receiving secondary prophylaxis with octreotide had a significantly lower GI bleed recurrence compared with historical controls not treated with octreotide. Additional prospective studies are needed to confirm these data. © 2017 American Heart Association, Inc.

The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality.

Although post-polypectomy bleeding is the most frequent complication after colonoscopic polypectomy, only few studies have investigated the incidence of bleeding prospectively. The aim of this study was to investigate the incidence of delayed post-polypectomy bleeding and its associated risk factors prospectively. Patients who underwent colonoscopic polypectomy at Kangbuk Samsung Hospital from January 2013 to December 2014 were prospectively enrolled in this study. Trained nurses contacted patients via telephone 7 and 30 days after polypectomy and completed a standardized questionnaire regarding the development of bleeding. Delayed post-polypectomy bleeding was categorized as minor or major and early or late bleeding. Major delayed bleeding was defined as a > 2-g/dL drop in the hemoglobin level, requiring hospitalization for control of bleeding or blood transfusion; late delayed bleeding was defined as bleeding occurring later than 24 h after polypectomy. A total of 8175 colonoscopic polypectomies were performed in 3887 patients. Overall, 133 (3.4%) patients developed delayed post-polypectomy bleeding. Among them, 90 (2.3%) and 43 (1.1%) patients developed minor and major delayed bleeding, respectively, and 39 (1.0%) patients developed late delayed bleeding. In the polyp-based multivariate analysis, young age (< 50 years; odds ratio [OR] 2.10; 95% confidence interval [CI] 1.18-3.68), aspirin use (OR 2.78; 95% CI 1.23-6.31), and polyp size of > 10 mm (OR 2.45; 95% CI 1.38-4.36) were significant risk factors for major delayed bleeding, while young age (< 50 years; OR 2.6; 95% CI 1.35-5.12) and immediate bleeding (OR 3.3; 95% CI 1.49-7.30) were significant risk factors for late delayed bleeding. Young age, aspirin use, polyp size, and immediate bleeding were found to be independent risk factors for delayed post-polypectomy bleeding.

Bleeding from anus is usually referred as rectal bleeding but actually rectal bleeding is defined as bleeding from lower colon or rectum, which means bleeding from a place distal to ligament of Treitz. This study was conducted to determine the frequency of different causes of rectal bleeding in patients at Ayub Teaching Hospital, Abbottabad. One hundred and seventy-five patients with evidence of rectal bleed, without gender discrimination were selected by non-probability convenient sampling from the out-patient department and general medical wards. Patients with suspected upper GI source of bleeding; acute infectious bloody diarrhoea and any coagulopathy were excluded from the study. All patients were subjected to fibre optic colonoscopy after preparation of the gut and findings were recorded. Where necessary, biopsy samples were also taken. Diagnosis was based on colonoscopic findings. A total of 175 patients (92 males and 83 females) with mean age 35.81±9.18 years were part of the study. Colonoscopy showed abnormal findings in 150 (85.7%) patients. The commonest diagnosis was haemorrhoids, which was found in 39 (22.3%) patients. It was followed by inflammatory bowel disease (IBD) in 30 (17.1%) patients, solitary rectal ulcer in 13 (7.4%) patients and polyps in 25 (14.3%) patients. Other less frequent findings were non-specific inflammation and fungating growths in rectum. Haemorrhoids was the leading cause of bleeding per rectum in this study, followed by evidence of IBD while infrequent findings of polyps and diverticuli indicate that these are uncommon in this region.

Profuse blood loss affects blood coagulation to various degrees. However, whether bleeding speed affects coagulation remains uncertain. This study aimed to evaluate the effect of bleeding speed on coagulation function. A total of 141 patients in the Department of Thoracic Surgery of our hospital were evaluated between January 2007 and February 2014. There are two groups of patients, those who received decortication for chronic encapsulated empyema were called the slow-bleeding group, and those who received thoracoscopic upper lobectomy were called the fast bleeding group; each group was further subdivided into three: group A, 1000 ml ≤ bleeding amount < 1500 ml; group B, 1500 ml ≤ bleeding amount < 1700 ml; group C, 1700 ml ≤ bleeding amount < 2000 ml. Then, coagulation function was assessed in all patients before and during surgery and at 1, 2, and 24 h after surgery, measuring prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, blood pressure, hematocrit, hemoglobin, and platelets. Bleeding duration was overtly longer in the slow-bleeding group than that in quick bleeding individuals (2.3 ± 0.25 h vs. 0.41 ± 0.13 h, P < 0.001). Fibrinogen, hematocrit, hemoglobin, and platelets strikingly decreased, whereas prothrombin time and APTT values significantly increased with bleeding amounts in both quick and slow-bleeding groups. Interestingly, compared with slow-bleeding patients, coagulation indices at each time point and bleeding amounts had significant differences in the quick bleeding group.Increased consumption of coagulation factors in quick bleeding may have greater impact on coagulation function.

Re-bleeding after initial hemostasis in peptic ulcer bleeding can be life threatening. Identification of factors associated with re-bleeding is important. The aims of this study were to determine incidence of rebleeding in patients with high risk peptic ulcer bleeding and to evaluate factors associated with rebleeding. Among patients diagnosed as upper gastrointestinal hemorrhage at seven hospitals in Daegu-Gyeongbuk, and one hospital in Gyeongnam, South Korea, from Feb 2011 to Dec 2013, 699 patients diagnosed as high risk peptic ulcer bleeding with Forrest classification above llb were included. The data were obtained in a prospective manner. Among 699 patients, re-bleeding occurred in 64 (9.2 %) patients. Second look endoscopy was significantly more performed in the non-rebleeding group than the rebleeding group (81.8 vs 62.5 %, p < 0.001). In multivariate analysis, use of non-steroidal anti-inflammatory agents, larger transfusion volume (≥5 units), and non-performance of second look endoscopy were found as risk factors for rebleeding in high risk peptic ulcer bleeding. In our study, rebleeding was observed in 9.2 % of patients with high risk peptic ulcer bleeding. Performance of second look endoscopy seems to lower the risk of rebleeding in high risk peptic ulcer bleeding patients and caution should be paid to patients receiving high volume transfusion and on medication with NSAIDs.

We aimed to compare clinical outcomes and early adverse events of operative management (OM), nonoperative management (NOM), and NOM with splenic artery embolization (SAE) in blunt splenic injury (BSI) and identify the prognostic factors. Medical records of 136 consecutive patients with BSI admitted to a trauma center from 2005 to 2010 were retrospectively reviewed. Patients were separated into three groups: OM, NOM, and SAE. We focused on associated injuries and early adverse events. Multivariate analysis was performed on 23 prognostic factors to find predictors. The total survival rate was 97.1%, with four deaths all occurred in the OM group. The spleen salvage rate was 91% in NOM and SAE. At least one adverse event was observed in 32.8%, 62%, and 96% of patients in NOM, SAE, and OM groups, respectively (P < 0.001). We found significantly more deaths, infectious complications, pleural drainage, acute renal failures, and pancreatitis in OM and more pseudocysts in SAE. Six prognostic factors were statistically significant for one or more adverse events: simplified acute physiology score 2 ≥25 for almost all adverse events, age ≥50 years for acute respiratory syndrome, limb fracture for secondary bleeding, thoracic injury for pleural drainage, and at least one associated injury for pseudocyst. Adverse events were not related to the type of BSI management. Patients with BSI present worse outcome and more adverse events in OM, but this is related to the severity of injury. The main predictor of adverse events remains the severity of injury.

Longest delayed hemothorax reported after blunt chest injury.

Blunt chest injury is a common presentation to the emergency department. However, a delayed hemothorax after blunt trauma is rare; current literature reports a delay of up to 30days. We present a case of 44-day delay in hemothorax which has not been previously reported in current literature. A 52-year-old Caucasian male first presented to the emergency department complaining of persistent right sided chest pain 2weeks after having slipped on a wet surface at home. His initial chest X-ray showed fractures of the right 7th and 8th ribs without a hemothorax or pneumothorax. He returned 30days after the initial consultation (44days post-trauma) having increasing shortness of breath. A chest X-ray this time revealed a large right hemothorax and 1850ml of blood drained from his chest. There was a complete resolution of the hemothorax within 48h and the patient was discharged after a 6-week follow-up with the chest physicians. Delayed hemothorax after blunt trauma is a rare clinical occurrence but associated with significant morbidity and mortality. The management of delayed hemothorax includes draining the hemothorax and controlling the bleeding. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be vigilant and weary that hemothorax could be a possibility after a chest injury despite a delay in presentation. A knowledge of delayed hemothorax will prompt physicians in providing important advice, warning signs and information to patients after a chest injury to avoid a delay in seeking medical attention.

Blunt cerebrovascular trauma causing vertebral arteryd issection in combination with a laryngeal fracture: a case report

PubMed Central

2011-01-01

Introduction The diagnosis and therapy of blunt cerebrovascular injuries has become a focus since improved imaging technology allows adequate description of the injury. Although it represents a rare injury the long-term complications can be fatal but mostly prevented by adequate treatment. Case presentation A 33-year-old Caucasian man fell down a 7-meter scarp after losing control of his quad bike in a remote area. Since endotracheal intubation was unsuccessfully attempted due to the severe cervical swelling as well as oral bleeding an emergency tracheotomy was performed on scene. He was hemodynamically unstable despite fluid resuscitation and intravenous therapy with vasopressors and was transported by a helicopter to our trauma center. He had a stable fracture of the arch of the seventh cervical vertebra and fractures of the transverse processes of C5-C7 with involvement of the lateral wall of the transverse foramen. An abort of the left vertebral artery signal at the first thoracic vertebrae with massive hemorrhage as well as a laryngeal fracture was also detected. Further imaging showed retrograde filling of the left vertebral artery at C5 distal of the described abort. After stabilization and reconfirmation of intracranial perfusion during the clinical course weaning was started. At the time of discharge, he was aware and was able to move all extremities. Conclusion We report a rare case of a patient with vertebral artery dissection in combination with a laryngeal fracture after blunt trauma. Thorough diagnostic and frequent reassessments are recommended. Most patients can be managed with conservative treatment. PMID:21843321

Portal hypertension (PH) is hemodynamical abnormality associated with the most serious complications of alcoholic liver cirrhosis (ALC): ascites, varices and variceal bleeding. The aim of this study was to determine characteristics of portal hypertension, especially of upper gastrointestinal bleedings in patients with alcoholic liver cirrhosis (ALC). A total of 237 patients with ALC were observed in a 3-year period. A total of 161 patients (68%) were hospitalized because of PH elements: 86 (36.3%) had upper gastrointestinal bleeding, 75 (31.7%) were decompensated. Only 76 (32%) of the patients had icterus. General mortality was 85 (36%). According to the source of bleeding, 61 (71%) patients bled from varices, and 25 (29%) from other sources with existing varices but non-incriminated for bleeding in 16 (64%) of those patients. Active bleeding or stigmata of recent bleeding were found in 63 (73%) cases. Endoscopic treatment of variceal bleeding along with octreotide applied in 20 (32.78%) patients, just octreotide in 32 (52.46%), and octreotid plus balloon tamponade in 9 (14.75%). According to Child-Pugh classification, 25 (29%) of the bleeding patients were in class A, score 5.4; 43 (50%) in class B, score 7.8; and 18 (21%) in class C, score 10.9. Average hemoglobin level was 93 g/L, hematocrit 0.27, AST 71.52 U/L (normal to 37 U/L), ALT 37.74 U/L (normal to 40 U/L). Until this bleeding episode, 41 (47%) of the patients already bled. In the decompensated patients 3 (4%) were in Child Pugh class A, score 6; 42 (56%) in class B, score 8.3; and 30 (40%) in class C, score 10.6. Until this decompensation episode, 7 (9.3%) patients already bled. Patients with ALC need early detection of varices, primary and secondary profilaxis of variceal bleeding and adequate therapy of ascites. When bleeding occurs, patients need urgent upper endoscopy and intensive treatment.

Although orbital compartment syndrome is a rare condition, it is still the most common cause of blindness following simple or complicated facial fractures. Its pathomechanism is similar to the compartment syndrome in the limb. Little extra fluid (blood, oedema, brain, foreign body) in a non-space yielding space results with increasingly higher pressures within a short period of time. Unless urgent surgical intervention is performed the blocked circulation of the central retinal artery will result irreversible ophthalmic nerve damage and blindness. Aim, material and method: A retrospective analysis of ten years, 2007-2017, in our hospital among those patients referred to us with facial-head trauma combined with blindness. 571 patients had fractures involving the orbit. 23 patients become blind from different reasons. The most common cause was orbital compartment syndrome in 17 patients; all had retrobulbar haematomas as well. 6 patients with retrobulbar haematoma did not develop compartment syndrome. Compartment syndrome was found among patient with extensive and minimal fractures such as with large and minimal haematomas. Early lateral canthotomy and decompression saved 7 patients from blindness. We can not predict and do not know why some patients develop orbital compartment syndrome. Compartment syndrome seems independent from fracture mechanism, comminution, dislocation, amount of orbital bleeding. All patients are in potential risk with midface fractures. We have a high suspicion that orbital compartment syndrome has been somehow missed out in the recommended textbooks of our medical universities and in the postgraduate trainings. Thus compartment syndrome is not recognized. Teaching, training and early surgical decompression is the only solution to save the blind eye. Orv Hetil. 2017; 158(36): 1410-1420.

Management of traumatic brachial artery injuries: A report on 49 patients

BACKGROUND AND OBJECTIVE: The brachial artery is the most frequently injured artery in the upper extremity due to its vulnerability. The purpose of our study was to review our experience with brachial artery injuries over a 9-year period, describing the type of injury, surgical procedures, complications, and associated injuries. PATIENTS AND METHODS: Forty-nine patients with brachial artery injury underwent surgical repair procedures at our hospital, from the beginning of May 1999 to the end of June 2008. The brachial artery injuries were diagnosed by physical examination and Doppler ultrasonography. Depending on the mode of presentation, patients were either taken immediately to the operating room for bleeding control and vascular repair or were assessed by preoperative duplex ultrasonography. RESULTS: This study group consisted of 43 males and 6 females, ranging in age from 6 to 65 years with a mean (SD) age of 27.9 (6.7) years. The mechanism of trauma was penetrating in 45 patients and blunt in the remaining 4 patients. Stab injury was the most frequent form of penetrating trauma (24 of 45). Treatment included primary arterial repair in 5 cases, end-to-end anastomosis in 28 cases, interposition vein graft in 15 cases, and interposition-ringed polytetrafluoroethylene graft in 1 case. Associated injuries were common and included venous injury (14), bone fracture (5), and peripheral nerve injury (11). Fifteen patients developed postoperative complications. One patient underwent an above-elbow amputation. CONCLUSIONS: Prompt and appropriate management of the brachial artery injuries, attention to associated injuries, and a readiness to revise the vascular repair early in the event of failure will maximize patient survival and upper extremity salvage.

Guidelines recommend the assessment of stroke and bleeding risk before initiating warfarin anticoagulation in patients with atrial fibrillation. Many of the elements used to predict stroke also overlap with bleeding risk in atrial fibrillation patients and it is tempting to use stroke risk scores to efficiently estimate bleeding risk. Comparison of stroke risk scores to bleeding risk scores to predict bleeding has not been thoroughly assessed. 2600 patients followed at seven anticoagulation clinics were followed from October 2009-May 2013. Five risk models (CHADS2, CHA2DS2-VASc, HEMORR2HAGES, HAS-BLED and ATRIA) were retrospectively applied to each patient. The primary outcome was the first major bleeding event. Area under the ROC curves were compared with C statistic and net reclassification improvement (NRI) analysis was performed. 110 patients experienced a major bleeding event in 2581.6 patient-years (4.5%/year). Mean follow up was 1.0±0.8years. All of the formal bleeding risk scores had a modest predictive value for first major bleeding events (C statistic 0.66-0.69), performing better than CHADS2 and CHA2DS2-VASc scores (C statistic difference 0.10 - 0.16). NRI analysis demonstrated a 52-69% and 47-64% improvement of the formal bleeding risk scores over the CHADS2 score and CHA2DS2-VASc score, respectively. The CHADS2 and CHA2DS2-VASc scores did not perform as well as formal bleeding risk scores for prediction of major bleeding in non-valvular atrial fibrillation patients treated with warfarin. All three bleeding risk scores (HAS-BLED, ATRIA and HEMORR2HAGES) performed moderately well. Copyright © 2014 Elsevier Ltd. All rights reserved.

We have recognized a unique clinical syndrome in patients with upper gastrointestinal bleeding who are found to have severe esophagitis. We aimed to more clearly describe the clinical entity of upper gastrointestinal bleeding in patients with severe esophagitis. We conducted a retrospective matched case-control study designed to investigate clinical features in patients with carefully defined upper gastrointestinal bleeding and severe esophagitis. Patient data were captured prospectively via a Gastrointestinal Bleeding Healthcare Registry, which collects data on all patients admitted with gastrointestinal bleeding. Patients with endoscopically documented esophagitis (cases) were matched with randomly selected controls that had upper gastrointestinal bleeding caused by other lesions. Epidemiologic features in patients with esophagitis were similar to those with other causes of upper gastrointestinal bleeding. However, hematemesis was more common in patients with esophagitis 86% (102/119) than in controls 55% (196/357) (p < 0.0001), while melena was less common in patients with esophagitis 38% (45/119) than in controls 68% (244/357) (p < 0.0001). Additionally, the more severe the esophagitis, the more frequent was melena. Patients with esophagitis had less abnormal vital signs, lesser decreases in hematocrit, and lesser increases in BUN. Both pre- and postRockall scores were lower in patients with esophagitis compared with controls (p = 0.01, and p < 0.0001, respectively). Length of hospital stay (p = 0.002), rebleeding rate at 42 days (p = 0.0007), and mortality were less in patients with esophagitis than controls. Finally, analysis of patients with esophagitis and cirrhosis suggested that this group of patients had more severe bleeding than those without cirrhosis. We have described a unique clinical syndrome in patients with upper gastrointestinal bleeding who have erosive esophagitis. This syndrome is manifest by typical clinical features and is associated with favorable outcomes.

Risk scores for patients who are at high risk for major bleeding complications during treatment with vitamin K antagonists (VKAs) do not perform that well. BLEEDS was initiated to search for new biomarkers that predict bleeding in these patients. To describe the outline and objectives of BLEEDS and to examine whether the study population is generalizable to other VKA treated populations. A cohort was created consisting of all patients starting VKA treatment at three Dutch anticoagulation clinics between January-2012 and July-2014. We stored leftover plasma and DNA following analysis of the INR. Of 16,706 eligible patients, 16,570 (99%) were included in BLEEDS and plasma was stored from 13,779 patients (83%). Patients had a mean age of 70 years (SD 14), 8713 were male (53%). The most common VKA indications were atrial fibrillation (10,876 patients, 66%) and venous thrombosis (3920 patients, 24%). 326 Major bleeds occurred during 17,613 years of follow-up (incidence rate 1.85/100 person years, 95%CI 1.66-2.06). The risk for major bleeding was highest in the initial three months of VKA treatment and increased when the international normalized ratio increased. These results and characteristics are in concordance with results from other VKA treated populations. BLEEDS is generalizable to other VKA treated populations and will permit innovative and unbiased research of biomarkers that may predict major bleeding during VKA treatment.

The clinical benefit and safety profile associated with first-line bevacizumab with doublet chemotherapy in patients with advanced non-squamous non-small cell lung cancer (NSCLC) was established in two large phase III studies, E4599 and AVAiL. SAiL, a single-arm phase IV study, was conducted to evaluate bevacizumab with a range of first-line chemotherapy regimens in a routine oncology practice setting. This analysis of the SAiL data was undertaken to specifically evaluate bleeding adverse events (AEs) in this study, and to explore potential associations between bleeding and baseline patient and disease characteristics. In total, 2212 patients were evaluated. Bleeding AEs (any grade) occurred in 38.2% of patients (grade ≥ 3 bleeding AEs: 3.6%). Grade ≥ 3 pulmonary hemorrhage and central nervous system bleeding events were observed in 0.7% and 0.1% of patients, respectively. The incidence of grade ≥ 3 bleeding AEs was comparable across patient subgroups defined by central tumor location, tumor cavitation, histology, concomitant anticoagulation therapy and age. The majority (88.6%) of bleeding events resolved or improved, 10.2% persisted and 1.3% led to death; 10.2% of bleeding events required bevacizumab interruption or discontinuation. This analysis from the SAiL trial reaffirms a comparable incidence of clinically significant bleeding associated with first-line bevacizumab and chemotherapy as previous phase III studies in NSCLC patients despite less stringent first-line selection criteria. Grade ≥ 3 bleeding appears to be comparable when analyzed for patient and tumor characteristics, including tumor cavitation and concomitant anticoagulation therapy. Most bleeding events resolved or improved, and interruption/discontinuation of bevacizumab was infrequent in a standard oncology practice setting. Copyright © 2012 Elsevier Ireland Ltd.

Anastomotic leakage, bleeding, and stricture are major complications after gastrectomy. Of these complications, postoperative anastomotic bleeding is relatively rare, but lethal if not treated immediately. Of 2031 patients with gastric cancer who underwent radical gastrectomy (R0 resection) between January 2002 and December 2010, postoperative anastomotic bleeding was observed in 7 patients. The clinicopathological features, postoperative outcomes such as surgical procedures, bleeding sites and, methods used to achieve hemostasis, and the risk factors of anastomotic bleeding of these 7 patients were analyzed. Of the 2031 patients, 1613 and 418 underwent distal and total gastrectomy, respectively. The bleeding sites were as follows: Billroth-I anastomosis using a circular stapler (n = 1), Billroth-II anastomosis by manual suture (n = 5), and esophagojejunostomy using a circular stapler (n = 1). All patients were treated with endoscopic clipping or epinephrine injection. There was no further endoscopic intervention or reoperation for anastomotic bleeding. Postoperative anastomotic bleeding is an infrequent but potentially life-threatening complication. Scrupulous surgical procedures are essential for the prevention of postoperative bleeding, and endoscopy was useful for both the confirmation of bleeding and therapeutic intervention.

The importance of pelvic ring stabilization as a life-saving measure in pre-hospital - A case report commented by autopsy.

Hip fractures with unstable pelvic ring have great morbidity and mortality rates. These fractures result from high energy trauma such as falls from heights, road accidents and collapsing structures or other similar mechanisms of action. We report the case of a 63 years old man, construction worker, who stood inside a ditch during a wall construction when he was surprised by this collapse, which resulted in direct trauma to the right thigh and pelvis. The autopsy revealed diaphysis fracture of the right femur with an open book pelvic fracture with severe hemorrhagic infiltration and hematoma of the pelvic muscles without arterial injury. Bone bleeding and the vascular damage associated with disruption of the sacroiliac ligaments promote a very significant bleeding. Simple maneuvers such as sheet circumferential compression to promote pelvic ring closure are effective on stabilizing and closure of the sacroiliac joint. Hip manipulation of the fracture was performed during the necropsy to demonstrate and prove how a simple sheet contention can promote stabilization of the pelvic ring by closing the sacroiliac joints in open book fractures.

The decision to perform a tracheostomy on patients with maxillofacial trauma is complex. There is little data exploring the role of tracheostomy in facial fracture management. We sought to profile the utilization of tracheostomy in the context of maxillofacial trauma at our institution by comparing patients who required tracheostomy with and without facial fractures versus those with facial fractures not requiring tracheostomy. All patients admitted to the Trauma Service at Legacy Emanuel Hospital and Health Center (LEHHC), Portland, OR, from 1993 to 2003 that sustained facial fractures or underwent tracheostomy were identified and data were retrospectively reviewed using patient charts and the trauma registry. Variables such as age, gender, death, injury severity score (ISS), facial injury severity score (FISS), Glasgow coma score (GCS), intensive care days (ICU), hospital length of stay (LOS), facial fracture profile, and oral and maxillofacial surgery (OMFS) operative intervention were tabulated and analyzed. Data were divided into 3 groups for comparison: group 1 (ffxT) consisted of patients who underwent a tracheostomy procedure and repair of their facial fracture during the SAME operation by the OMFS department (N = 125); group 2 (ffxNT) were those patients who had repair of their facial fractures by OMFS and did not require a tracheostomy (N = 224); and group 3 (NffxT) were patients who did not have facial fractures but received a tracheostomy during their hospitalization (N = 259). Ten-year data were used to analyze the ffxT and 5-year data were used to analyze the ffxNT and NffxT. Analysis of variance and chi2 testing was used for statistical analysis. A total of 18,187 patients were admitted to the trauma LEHHC Trauma Service during the study period, of which 1,079 (5.9%) patients sustained facial fractures and 788 (4.3%) required a tracheostomy. One hundred twenty-five patients (0.69% of total; 11.6% of facial fracture) received a tracheostomy at the same time as the facial fracture repair. All patients had their facial fractures successfully managed, regardless of the type of method used to stabilize the airway. There were no known cases of tracheal stenosis, severe bleeding requiring a return to the operating room, airway obstruction, or loss of secured airway. Males were the predominate gender in all 3 groups. The NffxT group (mean, 44.9 years) was much older compared with the ffxT (mean, 36.2 years) and ffxNT (mean, 30.9 years) groups. The incidence of death was higher in the tracheostomy groups compared with 0% with the non-tracheostomy group. The ffxNT group had a statistically significant higher GCS with an average of 12.4 when compared with the tracheostomy groups (ffxT = 6.8; NffxT = 6.7). ISS was nearly the same in the tracheostomy group (ffxT = 28.45; NffxT = 30.04), but higher when compared with the ffxNT (ISS = 17.33). All 3 groups were much different in terms of LOS and ICU days, in which the NffxT group had an average hospital LOS and ICU days of 34.4 and 16.56, respectively. This was higher when compared with the ffxT (LOS = 19.71 days; ICU = 7.21 days) and ffxNT (LOS = 6.82 days; ICU = 1.33 days) groups. The FISS averaged 6.22 in the ffxT group and was higher compared with an FISS of 3.16 in the ffxNT group. Overall, the fracture profile was different between the tracheostomy and non-tracheostomy groups. There was a higher prevalence of mandibular fractures, multiple mandibular fractures, and Le Fort III fractures in the ffxT group compared with the ffxNT group. Tracheostomy is commonly performed in the context of multisystem trauma and is a safe method for airway stabilization in patients with craniomaxillofacial trauma. Multi-institutional collaboration and a prospective, randomized trial measuring outcome, resource utilization, and length of ICU stay is necessary to determine if tracheostomy is indeed of measurable benefit to patients with complex injuries.

Intravenous lipid emulsion does not reverse dabigatran-induced anticoagulation in a rat model.

The anticoagulant dabigatran has no reversal agent and may cause life-threatening bleeding in patients with trauma or closed-space hemorrhage. Intravenous lipid emulsion (ILE) is thought to create a lipid compartment in serum that sequesters lipophilic drugs. Dabigatran is lipophilic, and its anticoagulant effects are concentration dependent. The study objective was to determine if ILE therapy reverses dabigatran's anticoagulant effects. Twenty rats were selected at random, 10 in the ILE group and 10 in a normal saline (NS) control group. Animals had a baseline tail bleeding time (T0), followed by oral dabigatran administration (15 mg/kg). At 45 minutes (T45), a second tail bleed time measurement was performed, followed by a 7-minute infusion of 15 mL/kg ILE or NS. A final 60-minute (T60) bleed time measurement was obtained. An ILE-only group of five animals had bleeding times assessed prior to (T0) and 15 minutes after (T15) ILE therapy. A mixed-effect repeated-measures analysis of variance modeling the effect of time, group, and the interaction of group and time on bleed times was conducted. There was a significant within-subject change in bleeding time across the assessment points (F(2,36) = 33; p < 0.001), but there were no effect of group (F(1,18) = 1.42, p = 0.25) or an interaction between group and assessment point on mean bleeding time (F(2,36) = 0.59, p = 56). Between T0 and T45, average bleeding times increased from 109.5 seconds (95% confidence interval [CI] = 94 to 125 seconds) to 231.8 seconds (95% CI = 193 to 271 seconds; p < 0.0001) for both the ILE group and the NS control group. Between T45 and T60, bleeding times in the ILE group decreased by 31.5 seconds (95% CI = -77 to 14 seconds) and by 6 seconds (95% CI = -67 to 55 seconds) in the NS group (p = 0.46). In the five ILE-only animals, the average bleeding time at T0 was 114 seconds (95% CI = 62 to 166 seconds), which increased significantly at T15 to 237 seconds (95% CI = 161 to 313 seconds; p = 0.02). The anticoagulant effects of dabigatran are not reversed with ILE therapy. Although ILE itself significantly prolonged bleeding times, when administered to dabigatran-anticoagulated rats, bleeding times did not change significantly. There may be a complex interaction of ILE with dabigatran that this study was not able to elucidate. © 2013 by the Society for Academic Emergency Medicine.

Background Bleeding following hospital discharge from percutaneous coronary intervention (PCI) is associated with increased risk of subsequent myocardial infarction (MI) and death, however the timing of adverse events following these bleeding events is poorly understood. Defining this relationship may help clinicians identify critical periods when patients are at highest risk. Methods and Results All patients undergoing PCI from 2004–2007 who survived to hospital discharge without a bleeding event were identified from the HMO Research Network-Stent Registry. Post-discharge rates and timing of bleeding-related hospitalizations, MI and death were defined. We then assessed the association between post-discharge bleeding-related hospitalizations with death and MI using Cox proportional hazards models. Among 8,137 post-PCI patients surviving to hospital discharge without in-hospital bleeding, 391 (4.8%) suffered bleeding-related hospitalization after discharge, with the highest incidence of bleeding-related hospitalizations occurring within 30 days of discharge (n=79, 20.2%). Post-discharge bleeding-related hospitalization after PCI was associated with subsequent death or MI (hazard ratio [HR] 3.09; 95% confidence interval [CI] 2.41–3.96), with the highest risk for death or MI occurring in the first 60 days after bleeding-related hospitalization (HR 7.16, CI 3.93–13.05). Conclusions Approximately 1 in 20 post-PCI patients are readmitted for bleeding, with the highest incidence occurring within 30 days of discharge. Patients suffering post-discharge bleeding are at increased risk for subsequent death or MI, with the highest risk occurring within the first 60 days following a bleeding-related hospitalization. These findings suggest a critical period after bleeding events when patients are most vulnerable for further adverse events. PMID:27301394

The advent of potent antiplatelet and antithrombotic agents over the past decade has resulted in significant improvement in reducing ischemic events in acute coronary syndrome (ACS). However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI), has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%–10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%–14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed. PMID:21915172

Traumatic injury to the retrohepatic veins continues to carry high mortality rates. In the last few decades various management strategies have been proposed. However, treatment of such injuries still remains highly variable and technically challenging due to the surgically inaccessible location of these vessels and the consequent difficulty controlling bleeding. We report a successful repair of complete transection of the two main extraparenchymal hepatic veins and laceration of the retrohepatic inferior vena cava using cardiopulmonary bypass (CPB) and hypothermic circulatory arrest (HCA) following blunt abdominal trauma. Immediate CPB with or without HCA can be life-saving and should be considered for patients with complex isolated retrohepatic venous injuries.

Objectives This study sought to determine if there is an association between bleed location and clinical outcomes in acute coronary syndromes (ACS) patients. Background The prognostic significance of bleeding location among ACS patients undergoing cardiac catheterization is not well known. Methods We analyzed in-hospital bleeding events among 9,978 patients randomized in the SYNERGY (Superior Yield of the New Strategy of Enoxaparin, Revascularization, and Glycoprotein IIb/IIIa Inhibitors) study. Bleeding events were categorized by location as access site, systemic, surgical, or superficial, and severity was graded using the GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definition. We assessed the association of each bleeding location and severity with 6-month risk of death or myocardial infarction using a multicovariate-adjusted Cox proportional hazard model. Results A total of 4,900 bleeding events were identified among 3,694 ACS patients with in-hospital bleeding. Among 4,679 GUSTO mild/moderate bleeding events, only surgical and systemic bleeds were associated with an increased risk of 6-month death or myocardial infarction (adjusted hazard ratio [HR]: 2.52 [95% confidence interval (CI): 2.16 to 2.94, and 1.40 [95% CI: 1.16 to 1.69], respectively). Mild/moderate superficial and access-site bleeds were not associated with downstream risk (adjusted HR: 1.17 [95% CI: 0.97 to 1.40], and 0.96 [95% CI: 0.82 to 1.12], respectively). Among 221 GUSTO severe bleeds, surgical bleeds were associated with the highest risk (HR: 5.27 [95% CI: 3.80 to 7.29]), followed by systemic (HR: 4.48 [95% CI: 2.98 to 6.72]), and finally access-site bleeds (HR: 3.57 [95% CI: 2.35 to 5.40]). Conclusions Among ACS patients who develop in-hospital bleeding, systemic and surgical bleeding are associated with the highest risks of adverse outcomes regardless of bleeding severity. Although the most frequent among bleeds, GUSTO mild/moderate access-site bleeding is not associated with increased risk. These data underscore the importance of strategies to minimize overall bleeding risk beyond vascular access site management. PMID:23866183

Hemorrhage is a leading cause of potentially preventable death in both civilian and military trauma patients. Animal data have shown that hemostatic bandages reduce hemorrhage and improve survival. This article reports recent clinical observations regarding the efficacy and evolution of use of two new hemostatic bandages employed in the global war on terrorism. We performed a retrospective cohort review of soldiers treated with either the QuikClot or HemCon hemostatic bandages between April and October 2006. Hemostatic dressings were placed on wounds either in the field or at the combat support hospital (CSH). During the 6-month study period, 1691 trauma patients were admitted to the CSH. Fifty uses of hemostatic dressings in 44 patients (2.6% of admissions) were identified. Forty patients were treated with HemCon dressings, three patients with QuikClot, and one with both QuikClot and HemCon. Eighteen percent of the dressings were used in the field, predominantly on extremity wounds (7/8). In contrast, most dressings used in the CSH were for truncal wounds (26/36 patients). Hemostatic dressings were applied to extremity wounds in prehospital and hospital settings, either alone or in conjunction with tourniquets. In surviving patients (95%), the treating surgeon determined that the hemorrhage was either stopped or greatly decreased by use of hemostatic dressings. Two of the four patients treated with QuikClot had burns from exothermic reactions, while no adverse reactions were noted with HemCon. Hemostatic agents stop or decrease bleeding. Whereas HemCon appears to be safe, QuikClot may produce superficial burns. These new hemostatic agents have a place in the surgical armamentarium to assist in controlling internal hemorrhage from truncal and pelvic hemorrhage, especially during damage-control surgery.

Uncertainty exists about the frequency, correlates, and clinical significance of bleeding with dual antiplatelet therapy (DAPT), particularly over an extended period in a stable population. We sought to determine the frequency and time course of bleeding with DAPT in patients with established vascular disease or risk factors only; identify correlates of bleeding; and determine whether bleeding is associated with mortality. We analyzed 15 603 patients enrolled in the Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization, Management, and Avoidance (CHARISMA) trial, a double-blind, placebo-controlled, randomized trial comparing long-term clopidogrel 75 mg/d versus placebo; all patients received aspirin (75 to 162 mg) daily. Patients had either established stable vascular disease or multiple risk factors for vascular disease without established disease. Median follow-up was 28 months. Bleeding was assessed with the use of the Global Utilization of Streptokinase and t-PA for Occluded Coronary Arteries (GUSTO) criteria. Severe bleeding occurred in 1.7% of the clopidogrel group versus 1.3% on placebo (P=0.087); moderate bleeding occurred in 2.1% versus 1.3%, respectively (P<0.001). The risk of bleeding was greatest the first year. Patients without moderate or severe bleeding during the first year were no more likely than placebo-treated patients to have bleeding thereafter. The frequency of bleeding was similar in patients with established disease and risk factors only. In multivariable analysis, the relationship between moderate bleeding and all-cause mortality was strong (hazard ratio, 2.55; 95% confidence interval, 1.71 to 3.80; P<0.0001), along with myocardial infarction (hazard ratio, 2.92; 95% confidence interval, 2.04 to 4.18; P<0.0001) and stroke (hazard ratio, 4.20; 95% confidence interval, 3.05 to 5.77; P<0.0001). In CHARISMA, there was an increased risk of bleeding with long-term clopidogrel. The incremental risk of bleeding was greatest in the first year and similar thereafter. Moderate bleeding was strongly associated with mortality. Clinical Trial Registration- URL: http://www.clinicaltrials.gov. Unique identifier: NCT00050817.

Critical role of oxygen radicals in the initiation of hepatic depression after trauma hemorrhage.

Although depression in hepatocellular function occurs early after trauma and severe hemorrhage and persists despite fluid resuscitation, it remains unknown whether reactive oxygen species (ROS) play any role in the initiation of hepatocellular depression and damage under those conditions. We hypothesized that administration of a ROS scavenger at the beginning of resuscitation will attenuate organ injury after severe shock. Male Sprague-Dawley rats (275-325 g) underwent laparotomy (i.e., induction of soft tissue trauma) and were then bled to and maintained at a mean arterial pressure of 40 mm Hg until 40% of the maximal bleed-out volume was returned in the form of Ringer's lactate. The animals were then resuscitated with four times the volume of maximal bleed-out with RL over 60 minutes. The ROS scavenger 2-mercaptopropionyl glycine (30 mg/kg) or vehicle was administered intravenously as a bolus at the beginning of resuscitation. At 2 hours after the completion of crystalloid resuscitation or the equivalent interval after sham-operation, cardiac index was measured by a dye dilution technique. Hepatocellular function, i.e., the maximum velocity of indocyanine green clearance (Vmax) and the efficiency of the active transport (Km), was determined using an in vivo hemoreflectometer. Serum levels of tumor necrosis factor (TNF)-alpha and alanine aminotransferase were determined with ELISA and colorimetrically, respectively. The results indicate that at 2 hours after trauma hemorrhage and resuscitation, cardiac index and hepatocellular function were markedly depressed with concomitantly increased serum levels of TNF-alpha and alanine aminotransferase (p < 0.05). Administration of 2-mercaptopropionyl glycine, however, restored the depressed cardiac and hepatic function and markedly attenuated liver enzyme release and serum levels of TNF-alpha (p < 0.05). Our data suggest that ROS play a role in producing the depression in organ functions after severe hemorrhagic shock. Thus, adjuncts that attenuate the detrimental effects of ROS may be useful for improving the depressed cardiac and hepatocellular functions after trauma hemorrhage and resuscitation.

To compare outcomes using the novel portable endoscopy with that of nasogastric (NG) aspiration in patients with gastrointestinal bleeding. Patients who underwent NG aspiration for the evaluation of upper gastrointestinal (UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration. In total, 129 patients who had GI bleeding signs or symptoms were included in the study (age 64.46 ± 13.79, 91 males). The UGI tract (esophagus, stomach, and duodenum) was the most common site of bleeding (81, 62.8%) and the cause of bleeding was not identified in 12 patients (9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration (85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding (88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding.

The risk of gastrointestinal (GI) bleeding with dabigatran when compared to warfarin has been controversial in the literature. The aim of our study was to assess this risk with the use of dabigatran. We examined the medical records of patients who were started on dabigatran or warfarin from October 2010 to October 2012. The study was conducted in two hospitals. A total of 417 patients were included (208 dabigatran vs. 209 warfarin). GI bleeding occurred in 10 patients (4.8%) in the dabigatran group compared to 21 patients (10.1%) in the warfarin group (p=0.0375). Multivariate analysis showed that patients who were on dabigatran for ≤ 100 days had a higher incidence of GI bleeding than those who were on it for >100 days (p=0.0007). The odds of GI bleeding in patients who were on dabigatran for ≤ 100 days was 8.2 times higher compared to those who were on the drug for >100 days. The incidence of GI bleeding in patients >65 years old was higher than in those <65 years old (p=0.0453, OR=3). History of previous GI bleeding was another risk factor for GI bleeding in the dabigatran group (p=0.036, OR=6.3). The lower GI tract was the most common site for GI bleeding in the dabigatran group (80.0% vs. 38.1%, p=0.014). The risk of GI bleeding was lower with dabigatran. The risk factors for GI bleeding with dabigatran were the first 100 days, age >65 years, and a history of previous GI bleeding.

Understanding the epidemiology of death after battlefield injury is vital to combat casualty care performance improvement. The current analysis was undertaken to develop a comprehensive perspective of deaths that occurred after casualties reached a medical treatment facility. Battle injury died of wounds (DOW) deaths that occurred after casualties reached a medical treatment facility from October 2001 to June 2009 were evaluated by reviewing autopsy and other postmortem records at the Office of the Armed Forces Medical Examiners (OAFME). A panel of military trauma experts classified the injuries as nonsurvivable (NS) or potentially survivable (PS), in consultation with an OAFME forensic pathologist. Data including demographics, mechanism of injury, physiologic and laboratory variables, and cause of death were obtained from the Joint Theater Trauma Registry and the OAFME Mortality Trauma Registry. DOW casualties (n = 558) accounted for 4.56% of the nonreturn to duty battle injuries over the study period. DOW casualties were classified as NS in 271 (48.6%) cases and PS in 287 (51.4%) cases. Traumatic brain injury was the predominant injury leading to death in 225 of 271 (83%) NS cases, whereas hemorrhage from major trauma was the predominant mechanism of death in 230 of 287 (80%) PS cases. In the hemorrhage mechanism PS cases, the major body region bleeding focus accounting for mortality were torso (48%), extremity (31%), and junctional (neck, axilla, and groin) (21%). Fifty-one percent of DOW casualties presented in extremis with cardiopulmonary resuscitation upon presentation. Hemorrhage is a major mechanism of death in PS combat injuries, underscoring the necessity for initiatives to mitigate bleeding, particularly in the prehospital environment.

Background and study aims  TC-325 (Hemospray, Cook Medical) is a powder agent for endoscopic hemostasis in patients with upper gastrointestinal bleeding (UGIB). Although most publications are based on case-reports and retrospective studies, data on efficacy are promising. Here we report our experience with TC-325 for diffuse or refractory UGIB. Patients and methods  Data on patients receiving TC-325 for endoscopic hemostasis from November 2013 to February 2017 at our center were analyzed retrospectively. Primary endpoints were technical success (successful immediate hemostasis) and clinical success (effective hemostasis and no recurrent bleeding). Secondary endpoints were recurrent bleeding within 3 and 7 days, hospital mortality and TC-325 associated complications. TC-325 was used for bleeding not amenable to standard endoscopic treatment (e. g. diffuse bleeding) or as salvage therapy after failure of conventional methods Results  Fifty-two patients received TC-325 treatment. Most of the patients were treated for peptic ulcer bleeding (18/52 patients, 34.6 %) and post-interventional bleeding (13/52 patients, 25 %). Hemospray was used in 23/52 (44.2 %) patients as monotherapy and in 29/52 (55.8 %) patients as a salvage therapy. Application of the powder on the bleeding source was successful in all patients with no therapy-related adverse events (AEs). Immediate hemostasis was achieved in 51/52 (98.1 %) patients. Recurrent bleeding within 3 and 7 days was observed in 22/51 and 25/51 patients respectively (43.1 % and 49 %). The overall clinical success was 56.9 % on day 3 and 51 % on day 7. Total mortality was 15.4 % (8 patients), bleeding associated mortality was 3.8 % (2 patients). There were no therapy-related AEs. Conclusions  TC-325 showed a high technical success rate as monotherapy for bleeding sources not amenable to standard methods or as an “add-on” therapy after unsuccessful hemostasis. However, rebleeding was frequent in this cohort and further studies are warranted to exactly define a treatment algorithm for TC-325 use. PMID:29124127

LAPAROSCOPIC MANAGEMENT OF RETROPERITONEAL INJURIES IN PENETRATING ABDOMINAL INJURIES.

2017-09-01

Laparoscopy in penetrating abdominal injuries is now accepted and practiced in many modern trauma centres. However its role in evaluating and managing retroperitoneal injuries is not yet well established. The aim of this study was to document our experience in using laparoscopy in a setting of penetrating abdominal injuries with suspected retroperitoneal injury in haemodynamically stable patients. A retrospective descriptive study of prospectively collected data from a trauma unit at Dr George Mukhari Academic Hospital (DGMAH) was done. All haemodynamically stable patients with penetrating abdominal injury who were offered laparoscopy from January 2012 to December 2015 were reviewed and those who met the inclusion criteria were analysed. A total of 284 patients with penetrating abdominal injuries were reviewed and 56 met the inclusion criteria and were analysed. The median age was 30.8 years (15-60 years) and males constituted 87.5% of the study population. The most common mechanism of injury was penetrating stab wounds (62.5%). Forty-five patients (80.3%) were managed laparoscopically, of these n=16 (28.5%) had retroperitoneal injuries that required surgical intervention. The most commonly injured organ was the colon (19.6%). The conversion rate was 19.6% with most common indication for conversion been active bleeding (14%). The complication rate was 7.14% (N=4) and were all Clavien-Dindo grade 3. There were no recorded missed injuries and no mortality. The positive outcomes documented in this study with no missed injuries and absence of mortality suggests that laparoscopy is a feasible option in managing stable patients with suspected retroperitoneal injuries.

Canalicular lacerations are common complications of eyelid trauma in the pediatric population. Irrigating air, water, and colored or viscous agents through the intact canaliculus have been suggested to identify the torn proximal edge. We report our experience in repairing canalicular lacerations using a novel viscoelastic injection technique with a Monoka monocanalicular stent. The medical records of patients <18 years of age who underwent repair of a canalicular laceration with a monocanalicular stent using superficial viscoelastic deployment to locate the torn canaliculus were retrospectively reviewed. Demographics, cause of eyelid injury, surgical management using our novel viscoelastic injection technique, and outcome were analyzed. A total of 38 children with lid lacerations were identified, of whom the 17 with canalicular involvement were included (mean age, 6.27 years). Canalicular injury in these 17 was due to dog bite (9 patients) and shearing trauma (8 patients). In 11 patients, the injury was located in the lower lid; in 4, the upper lid; and in 2, combined upper and lower lids. All patients had good anatomic repair and on follow-up had negative dye disappearance tests and were free of tearing. Deploying viscoelastic superficially near, and injecting into the injured canaliculus can improve visualization of the operative field by retracting the surrounding tissue and tamponading any bleeding, which aids in location and dilation of the torn canaliculus initially and in subsequent steps, eases intubation into the lubricated torn canaliculus and nasolacrimal duct, and avoids iatrogenic injury to an uninjured canaliculus.

This case report presents a newly diagnosed congenital factor VII deficiency treated with recombinant activated factor VII (rFVIIa). Congenital factor VII deficiency is a rare autosomal-recessive bleeding disorder that occurs in fewer than 1/500,000 persons. Its presentation can vary from epistaxis to hemarthroses and severe central nervous system bleeding, and correlates poorly with factor VII levels. Our patient had not had a significant hemostatic challenge prior to his presentation and therefore never had any symptomatology suggestive of this disease. He was treated with rFVIIa, and was able to undergo repair of his fractures without bleeding. Case report A 19-year-old African-American male presented to the emergency room after an altercation that resulted in significant trauma. He sustained bilateral mandibular angle fractures and orbital floor fractures, requiring urgent surgical correction. On initial evaluation, he was noted to have a prolonged prothrombin time of 40.1 seconds, with an International Normalized Ratio of 4.0, a normal activated partial thromboplastin time of 29.9 seconds, and a platelet count of 241. After receiving vitamin K and fresh frozen plasma, he was taken to the operating room for a temporary rigid maxillomandibular fixation. A 1:1 mixing study with normal plasma corrected the prothrombin time (decreasing from 40.7 to 14.7 seconds) and a factor VII assay revealed 5% of the normal factor VII level. The patient was diagnosed with congenital factor VII deficiency. Due to his coagulopathy and the extensive surgical correction needed, rFVIIa was administered and surgery was accomplished without hemorrhagic sequelae. Conclusion This case report and review describes a rare congenital disease, the history of rFVIIa use, and its mechanism. rFVIIA use in our patient provided a treatment option that allowed the necessary surgical correction, but further prospective studies on dose optimization would ensure adequate dosing with minimal risk of severe side effects.

Ultrasonic bone-cutting surgery has been introduced as a feasible alternative to the conventional sharp instruments used in craniomaxillofacial surgery because of its precision and safety. The piezosurgery medical device allows the efficient cutting of mineralized tissues with minimal trauma to soft tissues. Piezoelectric osteotome has found its role in surgically assisted rapid maxillary expansion (SARME), a procedure well established to correct transverse maxillary discrepancies. The advantages include minimal risk to critical anatomic structures. The purpose of this clinical comparative study (CIS 2007-237-M) was to present the advantages of the piezoelectric cut as a minimally invasive device in surgically assisted, rapid maxillary expansion by protecting the maxillary sinus mucosal lining. Thirty patients (18 females and 12 males) at the age of 18 to 54 underwent a surgically assisted palatal expansion of the maxilla with a combined orthodontic and surgical approach. The patients were randomly divided into two separate treatment groups. While Group 1 received conventional surgery using an oscillating saw, Group 2 was treated with piezosurgery. The following parameters were examined: blood pressure, blood values, required medication, bleeding level in the maxillary sinus, duration of inpatient stay, duration of surgery and height of body temperature. The results displayed no statistically significant differences between the two groups regarding laboratory blood values and inpatient stay. The duration of surgery revealed a significant discrepancy. Deploying piezosurgery took the surgeon an average of 10 minutes longer than working with a conventional-saw technique. However, the observation of the bleeding level in the paranasal sinus presented a major and statistically significant advantage of piezosurgery: on average the bleeding level was one category above the one of the remaining patients. This method of piezoelectric surgery with all its advantages is going to replace many conventional operating procedures in oral and maxillofacial surgery. CIS 2007-237-M.

Background Risk scores for patients who are at high risk for major bleeding complications during treatment with vitamin K antagonists (VKAs) do not perform that well. BLEEDS was initiated to search for new biomarkers that predict bleeding in these patients. Objectives To describe the outline and objectives of BLEEDS and to examine whether the study population is generalizable to other VKA treated populations. Methods A cohort was created consisting of all patients starting VKA treatment at three Dutch anticoagulation clinics between January-2012 and July-2014. We stored leftover plasma and DNA following analysis of the INR. Results Of 16,706 eligible patients, 16,570 (99%) were included in BLEEDS and plasma was stored from 13,779 patients (83%). Patients had a mean age of 70 years (SD 14), 8713 were male (53%). The most common VKA indications were atrial fibrillation (10,876 patients, 66%) and venous thrombosis (3920 patients, 24%). 326 Major bleeds occurred during 17,613 years of follow-up (incidence rate 1.85/100 person years, 95%CI 1.66–2.06). The risk for major bleeding was highest in the initial three months of VKA treatment and increased when the international normalized ratio increased. These results and characteristics are in concordance with results from other VKA treated populations. Conclusion BLEEDS is generalizable to other VKA treated populations and will permit innovative and unbiased research of biomarkers that may predict major bleeding during VKA treatment. PMID:27935941

A bleeding diathesis is a common feature of Noonan syndrome, and various coagulation abnormalities have been reported. Platelet function has never been carefully investigated. The degree of bleeding diathesis in a cohort of patients with Noonan syndrome was evaluated by a validated bleeding score and investigated with coagulation and platelet function tests. If ratios of prothrombin time and/or activated partial thromboplastin time were prolonged, the activity of clotting factors was measured. Individuals with no history of bleeding formed the control group. The study population included 39 patients and 28 controls. Bleeding score was ≥2 (ie, suggestive of a moderate bleeding diathesis) in 15 patients (38.5%) and ≥4 (ie, suggestive of a severe bleeding diathesis) in 7 (17.9%). Abnormal coagulation and/or platelet function tests were found in 14 patients with bleeding score ≥2 (93.3%) but also in 21 (87.5%) of those with bleeding score <2. The prothrombin time and activated partial thromboplastin time were prolonged in 18 patients (46%) and partial deficiency of factor VII, alone or in combination with the deficiency of other vitamin K-dependent factors, was the most frequent coagulation abnormality. Moreover, platelet aggregation and secretion were reduced in 29 of 35 patients (82.9%, P < .01 for all aggregating agents). Nearly 40% of patients with the Noonan syndrome had a bleeding diathesis and >90% of them had platelet function and/or coagulation abnormalities. Results of these tests should be taken into account in the management of bleeding or invasive procedures in these patients. Copyright © 2014 by the American Academy of Pediatrics.

The present clinical trial was designed to compare the results of bilateral inguinal hernia repair between patients who underwent the conventional Stoppa technique and laparoscopic total extraperitoneal repair (LTE) with a single mesh and without staple fixation. This controlled, randomised clinical trial was conducted at General Surgery and Trauma of the Clinics Hospital, Medical School, the University of São Paulo between September 2010 and February 2011. Totally, 50 male patients, with a bilateral inguinal hernia, older than 25 years were considered eligible for the study. The following parameters were analysed during the early post-operative period: (1) The intensity of surgical trauma, operation time, C-reactive protein (CRP) levels, white blood cell count, bleeding and pain intensity; (2) quality of life assessment; and (3) post-operative complications. LTE procedure was longer than the Stoppa procedure (134.6 min ± 38.3 vs. 90.6 min ± 41.3; P < 0.05). The levels of CRP were higher in the Stoppa group (P < 0.05) but the number of leucocytes, haematocrit, and haemoglobin were similar between the groups (P > 0.05). There was no difference in pain during the 1st and 7th post-operative, physical functioning, physical limitation, the impact of pain on daily activities, and the Carolinas Comfort Scale during the 7th and 15th post-operative (P > 0.05). Complications occurred in 88% of Stoppa group (22 patients) and 64% in LTE group (16 patients) (P < 0.05). The comparative study between the Stoppa and LTE approaches for the bilateral inguinal hernia repair demonstrated that: (1) The LTE approach showed less surgical trauma despite the longer operation time; (2) Quality of life during the early post-operative period were similar; and (3) Complication rates were higher in the Stoppa group.

To present a case report of a patient with Noonan syndrome who developed life-threatening gastrointestinal bleeding shortly after cardiac surgery that was successfully treated with recombinant factor VIIa. Case report. Pediatric intensive care unit of a children's hospital. Ten-month-old with Noonan syndrome and massive gastrointestinal bleeding resulting in severe hypovolemic shock. Recombinant factor VIIa was used in this patient's severe bleeding associated with Noonan syndrome after no other supportive measures were successful. Recombinant Factor VIIa significantly decreased the patient's bleeding and allowed his hypovolemic shock to improve. Ultimately, the patient made a complete recovery. Noonan syndrome has a constellation of both cardiac and noncardiac malformations including an increased risk of bleeding, and recombinant factor VIIa is an important agent in the treatment of significant bleeding.

Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall score; endoscopic data, including severity of lesions and therapy; feeding related records of seven days: liquid diet prescription, first liquid intake, soft/solid diet prescription, first soft/solid intake. From 133 patients (84 men) Rockall classification was possible in 126: 76 score ≥5, 50 score <5. One persistent bleeding, eight rebled, two underwent surgery, 13 died. Ulcer was the major bleeding cause, 63 patients underwent endoscopic therapy. There was 142/532 possible refeeding records, no record 37% patients. Only 16% were fed during the first day and half were only fed on third day or later. Rockall <5 patients started oral diet sooner than Rockall ≥5. Patients that underwent endoscopic therapy were refed earlier than those without endotherapy. Most feeding records are missing. Data reveals delayed refeeding, especially in patients with low-risk lesions who should have been fed immediately. Nonvariceal upper gastrointestinal bleeding patients must be refed earlier, according to guidelines.

To determine the risk factors, causes, and outcome of clinically important upper gastrointestinal bleeding that occurs in severely burned patients. The charts of all patients admitted to the burn intensive care unit were analyzed retrospectively over a 4-year period (from January 2006 to December 2009). Cases consisted of burned patients who developed upper gastrointestinal bleeding more than 24 hours after admission to the burn intensive care unit. Controls were a set of patients, in the burn intensive care unit, without upper gastrointestinal bleeding matched with cases for age and gender. Cases and controls were compared with respect to the risk factors of upper gastrointestinal bleeding and outcomes. During the study period, clinically important upper gastrointestinal bleeding occurred in 20 patients out of all 964 patients. The most common cause of upper gastrointestinal bleeding was duodenal ulcer (11 of 20 cases, 55%). In the multivariate analysis, mechanical ventilation (p = 0.044) and coagulopathy (p = 0.035) were found to be the independent predictors of upper gastrointestinal bleeding in severely burned patients. Upper gastrointestinal hemorrhage tends to occur more frequently after having prolonged mechanical ventilation and coagulopathy.

Death of patients presenting with bleeding events to the Emergency Department still represent a major problem. We sought to analyze clinical characteristics associated with worse outcomes including short- and long-term death, beyond antithombotic treatment strategy. Patients presenting with any bleeding events during 2016-2017years were enrolled. Clinical parameters, site of bleeding, major bleeding, ongoing anti-thrombotic treatment strategy and death were collected. Hard 5:1 propensity score matching was performed to adjust dead patients in baseline characteristics. Endpoints were one-month and one-year death. Out of 166,000 visits to the Emergency Department, 3.050 patients (1.8%) were enrolled and eventually 429 were analyzed after propensity. Overall, anticoagulants or antiplatelets were given to 234(54%). Major bleeding account for 111(26%) patients, without differences between those taking anticoagulants or antiplatelets versus others. Death at one-month and one-year was 26(6%) and 72(17%), respectively. Independent predictors of one-month death were major bleeding (Odds Ratio, OR 26, p<0.001), female gender (OR 7, p<0.001) and white blood cells (OR 1.2, p=0.01); of one-year were major bleeding (OR 7, p<0.001), age (OR 1.1, p<0.001) and female gender (OR 2.3, p=0.043). Of note, death rate of gastrointestinal and intracranial bleeding where higher than others (p<0.001). Overall mortality was approximately 40% on one-month; 60% in older patients and 80% in female gender with CHA 2 D 2 VASC-score≥2. Receiver operator characteristics analysis showed larger areas for major bleeding and age (0.75 and 0.72, respectively) over others; p<0.05 on C-statistic. In patients with bleeding events, death rate was driven by major bleeding on short-term and older age on long-term. Among dead patients mortality was approximately 40% on one-month; 60% in older patients, and 80% in female gender. Copyright © 2017 Elsevier Inc. All rights reserved.

Why Do Patients Bleed?

Patients undergoing surgical procedures can bleed for a variety of reasons. Assuming that the surgical procedure has progressed well and that the surgeon can exclude surgical reasons for the unexpected bleeding, then the bleeding may be due to structural (anatomical) anomalies or disorders, recent drug intake, or disorders of hemostasis, which may be acquired or congenital. The current review aims to provide an overview of reasons that patients bleed in the perioperative setting, and it also provides guidance on how to screen for these conditions, through consideration of appropriate patient history and examination prior to surgical intervention, as well as guidance on investigating and managing the cause of unexpected bleeding.

Biecker, Erwin

2013-01-01

Gastrointestinal bleeding related to portal hypertension is a serious complication in patients with liver cirrhosis. Most patients bleed from esophageal or gastric varices, but bleeding from ectopic varices or portal hypertensive gastropathy is also possible. The management of acute bleeding has changed over the last years. Patients are managed with a combination of endoscopic and pharmacologic treatment. The endoscopic treatment of choice for esophageal variceal bleeding is variceal band ligation. Bleeding from gastric varices is treated by injection with cyanoacrylate. Treatment with vasoactive drugs as well as antibiotic treatment is started before or at the time point of endoscopy. The first-line treatment for primary prophylaxis of esophageal variceal bleeding is nonselective beta blockers. Pharmacologic therapy is recommended for most patients; band ligation is an alternative in patients with contraindications for or intolerability of beta blockers. Treatment options for secondary prophylaxis include variceal band ligation, beta blockers, a combination of nitrates and beta blockers, and combination of band ligation and pharmacologic treatment. A clear superiority of one treatment over the other has not been shown. Bleeding from portal hypertensive gastropathy or ectopic varices is less common. Treatment options include beta blocker therapy, injection therapy, and interventional radiology. PMID:27335828

: To investigate perioperative and postoperative bleeding, complications in patients under therapy with anticoagulant or antiplatelet drugs submitted to oral surgery. To evaluate the risk of bleeding and safety for dental surgery, a retrospective chart review was performed. Medical and dental records of patients taking oral antithrombotic drugs undergoing dental surgery between 2010 and 2015 were reviewed. Results were statistically analyzed using Fisher's exact test, t test or the χ test. One hundred and seventy-nine patients underwent 293 surgical procedures. A total of eight cases of perioperative and 12 episodes of postoperative bleeding were documented. The complications were generally managed with local measures and did not require hospitalization. We found significant association of postoperative hemorrhage with increased perioperative bleeding (P = 0.043) and combination of anticoagulant and antiplatelet therapy (P < 0.001). The chance of postoperative hemorrhage for procedures with increased perioperative bleeding is 8.8 times bigger than procedures without perioperative bleeding. Dental surgery in patients under antithrombotic therapy might be carried out without altering the regimen because of low risk of perioperative and postoperative bleeding. However, patients with increased perioperative bleeding should be closely followed up because of postoperative complications risk.

 TC-325 (Hemospray, Cook Medical) is a powder agent for endoscopic hemostasis in patients with upper gastrointestinal bleeding (UGIB). Although most publications are based on case-reports and retrospective studies, data on efficacy are promising. Here we report our experience with TC-325 for diffuse or refractory UGIB.  Data on patients receiving TC-325 for endoscopic hemostasis from November 2013 to February 2017 at our center were analyzed retrospectively. Primary endpoints were technical success (successful immediate hemostasis) and clinical success (effective hemostasis and no recurrent bleeding). Secondary endpoints were recurrent bleeding within 3 and 7 days, hospital mortality and TC-325 associated complications. TC-325 was used for bleeding not amenable to standard endoscopic treatment (e. g. diffuse bleeding) or as salvage therapy after failure of conventional methods.  Fifty-two patients received TC-325 treatment. Most of the patients were treated for peptic ulcer bleeding (18/52 patients, 34.6 %) and post-interventional bleeding (13/52 patients, 25 %). Hemospray was used in 23/52 (44.2 %) patients as monotherapy and in 29/52 (55.8 %) patients as a salvage therapy. Application of the powder on the bleeding source was successful in all patients with no therapy-related adverse events (AEs). Immediate hemostasis was achieved in 51/52 (98.1 %) patients. Recurrent bleeding within 3 and 7 days was observed in 22/51 and 25/51 patients respectively (43.1 % and 49 %). The overall clinical success was 56.9 % on day 3 and 51 % on day 7. Total mortality was 15.4 % (8 patients), bleeding associated mortality was 3.8 % (2 patients). There were no therapy-related AEs.  TC-325 showed a high technical success rate as monotherapy for bleeding sources not amenable to standard methods or as an "add-on" therapy after unsuccessful hemostasis. However, rebleeding was frequent in this cohort and further studies are warranted to exactly define a treatment algorithm for TC-325 use.

Non-vitamin K antagonist oral anticoagulants (NOACs) are effective at preventing stroke in patients with atrial fibrillation (AF). However, little is known about the management of bleeding in contemporary, clinical use of NOACs. We aimed to assess the frequency, management, and outcomes of major bleeding in the setting of community use of NOACs. Using the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II registry, we analyzed rates of International Society on Thrombosis and Haemostasis major bleeding and subsequent outcomes in patients treated with NOACs versus warfarin. Outcomes of interest included acute and chronic bleeding management, recurrent bleeding, thromboembolic events, and death. In total, 344 patients with atrial fibrillation experienced major bleeding events over a median follow-up of 360 days follow-up: n = 273 on NOAC (3.3 per 100 patient-years) and n = 71 on warfarin (3.5 per 100 patient-years). Intracranial bleeding was uncommon but similar (0.34 per 100 patient-years for NOAC vs 0.44 for warfarin, p = 0.5), as was gastrointestinal bleeding (1.8 for NOAC vs 1.3 for warfarin, p = 0.1). Blood products and correction agents were less commonly used in NOAC patients with major bleeds compared with warfarin-treated patients (53% vs 76%, p = 0.0004 for blood products; 0% vs 1.5% for recombinant factor; p = 0.0499); no patients received pharmacologic hemostatic agents (aminocaproic acid, tranexamic acid, desmopressin, aprotinin). Within 30 days, 23 NOAC-treated patients (8.4%) died versus 5 (7.0%) on warfarin (p = 0.7). At follow-up, 126 NOAC-treated (46%) and 29 warfarin-treated patients (41%) were not receiving any anticoagulation. In conclusion, rates of major bleeding are similar in warfarin and NOAC-treated patients in clinical practice. However, NOAC-related bleeds require less blood product administration and rarely require factor replacement. Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.

Stroke and systemic thromboembolism are serious problems for patients with atrial fibrillation (AF), but their incidence can be substantially reduced by appropriate anticoagulation. Bleeding is the major complication of anticoagulant treatment, and the relative risks for bleeding vs stroke must be considered when starting anticoagulation. The AFFIRM trial included patients with AF and at least one risk factor for stroke, randomly assigning them to either a rate-control or rhythm-control strategy. All patients were initially treated with warfarin. The incidence of protocol-defined major and minor bleeding was documented during follow-up. Variables associated with bleeding were determined using a Cox proportional hazards model, using baseline and time-dependent covariates. The 4060 patients in the AFFIRM trial were followed for an average of 3.5 years. Major bleeding occurred in 260 patients, an annual incidence of approximately 2% per year, with no significant difference between the rate-control and rhythm-control groups. Increased age, heart failure, hepatic or renal disease, diabetes, first AF episode, warfarin use, and aspirin use were significantly associated with major bleeding. Minor bleeding was common in both treatment arms, with 738 patients reporting this problem in one or more visits. Bleeding is a significant problem that complicates management of patients with AF. Risk factors for bleeding can be identified, and knowledge of these risk factors can be used to plan therapy.

AIM: To evaluate the effectiveness of barium impaction therapy for patients with colonic diverticular bleeding. METHODS: We reviewed the clinical charts of patients in whom therapeutic barium enema was performed for the control of diverticular bleeding between August 2010 and March 2012 at Yokohama Rosai Hospital. Twenty patients were included in the review, consisting of 14 men and 6 women. The median age of the patients was 73.5 years. The duration of the follow-up period ranged from 1 to 19 mo (median: 9.8 mo). Among the 20 patients were 11 patients who required the procedure for re-bleeding during hospitalization, 6 patients who required it for re-bleeding that developed after the patient left the hospital, and 3 patients who required the procedure for the prevention of re-bleeding. Barium (concentration: 150 w%/v%) was administered per the rectum, and the leading edge of the contrast medium was followed up to the cecum by fluoroscopy. After confirmation that the ascending colon and cecum were filled with barium, the enema tube was withdrawn, and the patient’s position was changed every 20 min for 3 h. RESULTS: Twelve patients remained free of re-bleeding during the follow-up period (range: 1-19 mo) after the therapeutic barium enema, including 9 men and 3 women with a median age of 72.0 years. Re-bleeding occurred in 8 patients including 5 men and 3 women with a median age of 68.5 years: 4 developed early re-bleeding, defined as re-bleeding that occurs within one week after the procedure, and the remaining 4 developed late re-bleeding. The DFI (disease-free interval) decreased 0.4 for 12 mo. Only one patient developed a complication from therapeutic barium enema (colonic perforation). CONCLUSION: Therapeutic barium enema is effective for the control of diverticular hemorrhage in cases where the active bleeding site cannot be identified by colonoscopy. PMID:25987779

Blood autotransfusion outcomes compared with Ringer lactate infusion in dogs with hemorrhagic shock induced by controlled bleeding*

BACKGROUND: The most common cause of shock in the surgical or trauma patient is hemorrhage. Crystalloid solutions and blood transfusion are the mainstays of treatment of hemorrhagic shock. Considering the disadvantages of allogeneic blood transfusion, such as risk of transmission of infectious diseases, and access and maintenance limitations, treatment of shock with autologous blood seems to be a decent solution. Autologous blood accumulated in body cavities in traumatic bleeding (such hemothorax), and bloodshed in operation field during open heart or vascular surgeries, and similar situations, can be utilized again. In this study, autotransfusion effects compared with crystalloid fluid in the treatment of hemorrhagic shock was investigated. METHODS: After induction of hemorrhagic shock in dogs by Wiggers type controlled bleeding, treating them in a group with autologous blood and another group with Ringer lactate were performed, and the results of treatment were studied. RESULTS: There was no mortality in both treatment approaches. Immediately after treatment, crystalloid positive effects such as renormalized vital signs and appropriate consciousness were more noticeable than autotransfusion, while twenty-four hours after, the desired effects of autologous blood were more pronounced like decreased metabolic acidosis and improvement of diuresis. CONCLUSIONS: Crystalloid during the first hours after treatment of hemorrhagic shock may be better than autologous blood as preferred treatment, while autotransfusion showed its benefits some hours after. This finding can be used to develop better strategies for treatment of hemorrhagic shock. PMID:22973328

Postpartum Hemorrhage.

Interventional radiologists are often called for emergent control of abnormal uterine bleeding. Bleeding, even heavy bleeding as a result of uterine fibroids is not a common emergent procedure; instead, pregnancy and pregnancy related conditions, trauma and malignancy associated with bleeding can be the source of many interventional radiology on call events or procedures. Postpartum hemorrhage (PPH) is the most common cause, and is defined as blood loss of 500mL after vaginal delivery or 1000mL after cesarean section. Several authors have suggested a simpler definition of any amount of blood loss that creates hemodynamic instability in the mother. Regardless, PPH can be a life-threatening emergency and is a leading cause of maternal mortality requiring prompt action. Primary PPH is bleeding within the first 24 hour of delivery and secondary PPH is hemorrhage that occurs more than 24 hour after delivery. In addition to death, other serious morbidity resulting from postpartum bleeding includes shock, adult respiratory distress syndrome, coagulopathy, and loss of fertility due to hysterectomy. Transcatheter uterine artery embolization was first introduced as a treatment for PPH in 1979. It is a nonsurgical, minimally invasive, extremely safe and effective treatment for controlling excessive bleeding of the female reproductive track usually after conservative measures have failed, yet somewhat underused. Referring providers have limited awareness of the procedure. In hospitals where interventional radiologists have the experience and technical expertise to perform pelvic arteriography and embolization, this therapeutic option can play a pivotal role in the management of emergent obstetric hemorrhage.

Background Massive transfusion protocols (MTPs) have become standard of care in the management of bleeding injured patients, yet strategies to guide them vary widely. We conducted a pragmatic, randomized clinical trial (RCT) to test the hypothesis that an MTP goal directed by the viscoelastic assay thrombelastography (TEG) improves survival compared with an MTP guided by conventional coagulation assays (CCA). Methods This RCT enrolled injured patients from an academic level-1 trauma center meeting criteria for MTP activation. Upon MTP activation, patients were randomized to be managed either by an MTP goal directed by TEG or by CCA (ie, international normalized ratio, fibrinogen, platelet count). Primary outcome was 28-day survival. Results One hundred eleven patients were included in an intent-to-treat analysis (TEG = 56, CCA = 55). Survival in the TEG group was significantly higher than the CCA group (log-rank P = 0.032, Wilcoxon P = 0.027); 20 deaths in the CCA group (36.4%) compared with 11 in the TEG group (19.6%) (P = 0.049). Most deaths occurred within the first 6 hours from arrival (21.8% CCA group vs 7.1% TEG group) (P = 0.032). CCA patients required similar number of red blood cell units as the TEG patients [CCA: 5.0 (2–11), TEG: 4.5 (2–8)] (P = 0.317), but more plasma units [CCA: 2.0 (0–4), TEG: 0.0 (0–3)] (P = 0.022), and more platelets units [CCA: 0.0 (0–1), TEG: 0.0 (0–0)] (P = 0.041) in the first 2 hours of resuscitation. Conclusions Utilization of a goal-directed, TEG-guided MTP to resuscitate severely injured patients improves survival compared with an MTP guided by CCA and utilizes less plasma and platelet transfusions during the early phase of resuscitation.

To evaluate whether the risk of cardiovascular events increases when antithrombotics are discontinued after ulcer bleeding. Peptic ulcer bleeding associated with antithrombotics has increased due to the increase in the proportion of elderly population. Little is known about the long-term effects of discontinuing antithrombotics after peptic ulcer bleeding. The aim of this study was to evaluate whether the risk of cardiovascular events increases when antithrombotics are discontinued after ulcer bleeding. We reviewed the medical records of patients with ulcer bleeding who were taking antiplatelet agents or anticoagulants at the time of ulcer bleeding. Cox-regression model was used to adjust for potential confounders, and analyzed association between discontinuation of antithrombotic drugs after ulcer bleeding and thrombotic events such as ischemic heart disease or stroke. Of the 544 patients with ulcer bleeding, 72 patients who were taking antithrombotics and followed up for >2 months were analyzed. Forty patients discontinued antithrombotics after ulcer bleeding (discontinuation group) and 32 patients continued antithrombotics with or without transient interruption (continuation group). Thrombotic events developed more often in discontinuation group than in the continuation group [7/32 (21.9%) vs. 1/40 (2.5%), P=0.019]. Hazard ratio for thrombotic event when antithrombotics were continuously discontinued was 10.9 (95% confidence interval, 1.3-89.7). There were no significant differences in recurrent bleeding events between the 2 groups. Discontinuation of antithrombotics after peptic ulcer bleeding increases the risk of cardiovascular events. Therefore, caution should be taken when discontinuing antithrombotics after ulcer bleeding.

An innovative outcome-based care and procurement model of hemophilia management.

PubMed

Gringeri, Alessandro; Doralt, Jennifer; Valentino, Leonard A; Crea, Roberto; Reininger, Armin J

2016-06-01

Hemophilia is a rare bleeding disorder associated with spontaneous and post-traumatic bleeding. Each hemophilia patient requires a personalized approach to episodic or prophylactic treatment, but self-management can be challenging for patients, and avoidable bleeding may occur. Patient-tailored care may provide more effective prevention of bleeding, which in turn, may decrease the likelihood of arthropathy and associated chronic pain, missed time from school or work, and progressive loss of mobility. A strategy is presented here aiming to reduce or eliminate bleeding altogether through a holistic approach based on individual patient characteristics. In an environment of budget constraints, this approach would link procurement to patient outcome, adding incentives for all stakeholders to strive for optimal care and, ultimately, a bleed-free world.

This case series reports the outcomes of 8 patients (ages 9-4 years) who presented with 9 immature permanent teeth with pulpal necrosis and apical periodontitis. During treatment, 5 of the teeth were found to have at least some residual vital tissue remaining in the root canal systems. After NaOCI irrigation and medication with ciprofloxacin, metronidazole, and minocycline, these teeth were sealed with mineral trioxide aggregate and restored. The other group of 4 teeth had no evidence of any residual vital pulp tissue. This second group of teeth was treated with NaOCl irrigation and medicated with ciprofloxacin, metronidazole, and minocycline followed by a revascularization procedure adopted from the trauma literature (bleeding evoked to form an intracanal blood clot). In both groups of patients, there was evidence of satisfactory postoperative clinical outcomes (1-5 years); the patients were asymptomatic, no sinus tracts were evident, apical periodontitis was resolved, and there was radiographic evidence of continuing thickness of dentinal walls, apical closure, or increased root length.

Bleeding manifestations among patients with rare bleeding disorders (RBDs) vary significantly between disorders and patients, even when affected with the same disorder. In response to the challenge represented by the clinical assessment of the presence and severity of bleeding symptoms, a number of bleeding score systems (BSSs) or bleeding assessment tools (BATs) were developed. The majority of these were specifically developed for patients with more common bleeding disorders than RBDs. Few RBDs patients were evaluated with these tools and without conclusive results. A new BSS was developed using data retrieved from a large group of patients with RBDs enrolled in the EN-RBD database and from healthy subjects. These data included previous bleeding symptoms, frequency, spontaneity, extent, localization, and relationship to prophylaxis and acute treatment. The predictive power of this BSS was also compared with the ISTH-BAT and examined for the severity of RBDs based on coagulant factor activity. This BSS was able to differentiate patients with RBDs from healthy individuals with a bleeding score value of 1.5 having the highest sum of sensitivity (67.1%) and specificity (73.8%) in discriminating patients with RBD from those without. An easy-to-use calculation was also developed to assess the probability of having a RBD. Its comparison with the ISTH-BAT confirmed its utility. Finally, in RBDs patients, there was a significant negative correlation between BS and coagulant factor activity level, which was strongest for fibrinogen and FXIII deficiencies. The use of this quantitative method may represent a valuable support tool to clinicians. Copyright © 2016 Elsevier Ltd. All rights reserved.

[Gastrointestinal bleeding in the elderly].

PubMed

Glaser, J

2014-08-01

Peptic ulcer disease is a common cause of gastrointestinal bleeding, independent of the patient's age. With advancing age, an increase of lower gastrointestinal bleeding (diverticula, angiodysplasia) has been observed. The administration of non-steroidal anti-inflammatory drugs and aspirin is an important risk factor for upper and lower gastrointestinal bleeding, thus in patients aged 65 years and more a concomitant therapy with proton pump inhibitors is recommended in order to prevent ulcer bleeding. Even in very old individuals endoscopy should be used for the diagnosis of gastrointestinal bleeding, providing the opportunity for definite endoscopic bleeding therapy. In elderly patients with comorbidities and recurrent bleeding after endoscopic therapy or continuous blood loss, surgery or transarterial embolisation should be considered in good time.

The aim of the study is to examine the importance of Rockall scoring system in long-term setting to estimate re-bleeding and mortality rate due to upper gastrointestinal bleeding. A total of 321 patients who had been treated for upper gastrointestinal bleeding were recruited to the study. Patients' demographic and clinical data, the amount of blood transfusion, endoscopy results, and Rockall scores were retrieved from patients' charts. The re-bleeding, morbidity, and mortality rates were noted after 3 years of follow-up with telephone. Re-bleeding rate was statistically significantly higher in Rockall 4 group compared to Rockall 0 group. Mortality rate was also statistically significantly higher in Rockall 4 group. Rockall risk scoring system is a valuable tool to predict re-bleeding and mortality rates for patients with upper gastrointestinal bleeding in long-term setting.

AIM: To compare outcomes using the novel portable endoscopy with that of nasogastric (NG) aspiration in patients with gastrointestinal bleeding. METHODS: Patients who underwent NG aspiration for the evaluation of upper gastrointestinal (UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration. RESULTS: In total, 129 patients who had GI bleeding signs or symptoms were included in the study (age 64.46 ± 13.79, 91 males). The UGI tract (esophagus, stomach, and duodenum) was the most common site of bleeding (81, 62.8%) and the cause of bleeding was not identified in 12 patients (9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration (85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding (88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. CONCLUSION: The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding. PMID:25009396

The goal of this study was to retrospectively assess the efficacy of emergency percutaneous transcatheter arterial embolization in patients with severe bleeding due to upper gastrointestinal or jejunal tumor. Twelve patients (7 men, 5 women; mean age, 74 years±14 (SD); range: 54-86 years) with severe bleeding from the upper gastrointestinal tract, with failed endoscopic treatment not eligible for emergency surgery were treated by emergency percutaneous transcatheter arterial embolization. The bleeding cause was gastric tumor in 7 patients, duodenal tumor in 4 patients and jejunal tumor in one patient. Procedure details and follow-up were reviewed. Twelve embolization procedures were performed using various embolic agents. Embolization was achieved and bleeding was stopped in all patients. Five patients underwent surgery within the 30 days following embolization. In the remaining 7 patients, no bleeding occurred at 1 month follow-up in 6 patients and bleeding recurred in one patient at 1 month. In this later patient, endoscopic treatment was successful. The results of our study suggest that transcatheter arterial embolization is safe and effective in patients with severe arterial bleeding due to upper gastrointestinal or jejunal tumor. In some patients, transcatheter arterial embolization can be used as a bridge to surgery. Copyright © 2016 Éditions françaises de radiologie. Published by Elsevier Masson SAS. All rights reserved.

Acute upper gastrointestinal bleeding (UGIB) affects large number of elderly with high rates of morbidity and mortality. Early identification and management of the factors predicting in-hospital mortality might decrease mortality. This study was conducted to identify the causes of acute UGIB and the predictors of in-hospital mortality in elderly Egyptian patients.286 elderly patients with acute UGIB were divided into: bleeding variceal group (161 patients) and bleeding nonvariceal group (125 patients). Patients' monitoring was done during hospitalization to identify the risk factors that might predict in-hospital mortality in elderly.Variceal bleeding was the most common cause of acute UGIB in elderly Egyptian patients. In-hospital mortality rate was 8.74%. Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding were the predictors of in-hospital mortality.Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding should be considered when triaging those patients for immediate resuscitation, close observation, and early treatment.

No scoring system for evaluating the bleeding risk of atrial fibrillation (AF) patients after drug-eluting stent (DES) implantation with triple antithrombotic therapy (TAT) is available. We aimed to develop a new scoring system for predicting bleeding complications in AF patients after DES implantation with TAT. Between April 2007 and April 2014, 227 AF patients undergoing DES implantation with TAT were enrolled. Bleeding incidence defined as Bleeding Academic Research Consortium criteria≥2 was investigated and predictors of bleeding complications were evaluated using multivariate analysis. Bleeding complications occurred in 58 patients (25.6%) during follow-up. Multivariate analysis revealed dual antiplatelet therapy (DAPT) continuation (OR 3.33, P=0.01), age>75 (OR 2.14, P=0.037), international normalized ratio>2.2 (OR 5.82, P<0.001), gastrointestinal ulcer history (OR 3.06, P=0.037), and anemia (OR 2.15, P=0.042) as predictors of major bleeding complications. A score was created using the weighted points proportional to the beta regression coefficient of each variable. The DAIGA score showed better predictive ability for bleeding complications than the HAS-BLED score (AUC: 0.79 vs. 0.62, P=0.0003). Bleeding incidence was well stratified: 17.8% in low-risk (scores 0-1), 55.5% in moderate-risk (2-3), and 83.0% in high-risk (4-7) patients (P<0.001). This scoring system is useful for predicting bleeding complications and risk stratification of AF patients after DES implantation with TAT. Copyright © 2016 Elsevier Ireland Ltd.

Very elderly patients (age ≥ 85 years) are a rapidly increasing segment of the population. As a group, they experience high rates of in-hospital mortality and bleeding complications following percutaneous coronary intervention (PCI). However, the relationship between bleeding and mortality in the very elderly is unknown. Retrospective review was performed on 17,378 consecutive PCI procedures from 2000 to 2015 at Dartmouth-Hitchcock Medical Center. Incidence of bleeding during the index PCI admission (bleeding requiring transfusion, access site hematoma > 5 cm, pseudoaneurysm, and retroperitoneal bleed) and in-hospital mortality were reported for four age groups (< 65 years, 65-74 years, 75-84 years, and ≥ 85 years). The mortality of patients who suffered bleeding complications and those who did not was calculated and multivariate analysis was performed for in-hospital mortality. Lastly, known predictors of bleeding were compared between patients age < 85 years and age ≥ 85 years. Of 17,378 patients studied, 1019 (5.9%) experienced bleeding and 369 (2.1%) died in-hospital following PCI. Incidence of bleeding and in-hospital mortality increased monotonically with increasing age (mortality: 0.94%, 2.27%, 4.24% and 4.58%; bleeding: 3.96%, 6.62%, 10.68% and 13.99% for ages < 65, 65-74, 75-84 and ≥ 85 years, respectively). On multivariate analysis, bleeding was associated with increased mortality for all age groups except patients age ≥ 85 years [odds ratio (95% CI): age < 65 years, 3.65 (1.99-6.74); age 65-74 years, 2.83 (1.62-4.94); age 75-84 years, 3.86 (2.56-5.82), age ≥ 85 years: 1.39 (0.49-3.95)]. Bleeding and mortality following PCI increase with increasing age. For the very elderly, despite high rates of bleeding, bleeding is no longer predictive of in-hospital mortality following PCI.

Gastrointestinal bleeding is one of the most common indications for urgent endoscopy in the pediatric setting. The majority of these procedures are performed for control of variceal bleeding, with few performed for nonvariceal upper gastrointestinal (NVUGI) bleeding. The data on therapeutic endoscopy for NVUGI are sparse. The aims of our study were to review our experience with NVUGI bleeding, describe technical aspects and outcomes of therapeutic endoscopy, and determine gastroenterology fellows' training opportunities according to the national training guidelines. We performed a retrospective review of endoscopy database (Endoworks, Olympus Inc, Center Valley, PA) from January 2009 to December 2014. The search used the following keywords: bleeding, hematemesis, melena, injection, epinephrine, cautery, clip, and argon plasma coagulation. The collected data included demographics, description of bleeding lesion and medical/endoscopic therapy, rate of rebleeding, relevant laboratories, physical examination, and need for transfusion and surgery. The study was approved by the institutional review board. During the study period 12,737 upper endoscopies (esophagogastroduodenoscopies) were performed. A total of 15 patients underwent 17 esophagogastroduodenoscopies that required therapeutic intervention to control bleeding (1:750 procedures). The mean ± standard deviation (median) age of patients who required endoscopic intervention was 11.6 ± 6.0 years (14.0 years). Seven out of 17 patients received dual therapy to control the bleeding lesions. All but 3 patients received medical therapy with intravenous proton pump inhibitor, and 3 received octreotide infusions. Six of the patients experienced rebleeding (40%), with 4 out of 6 initially only receiving single modality therapy. Two of these patients eventually required surgical intervention to control bleeding and both patients presented with bleeding duodenal ulcers. There were no cases of aspiration, perforation, or deaths. There were a total of 24 fellows trained in our program during the study period. Less than 1 therapeutic endoscopy per fellow for NVUGI bleeding was performed. NVUGI bleeding requiring therapeutic endoscopic intervention is rare in pediatrics. A high rate (40%) of rebleeding was noted with a large proportion (66%) of patients receiving single modality therapy. Two patients required surgical intervention to control bleeding and both presented with bleeding duodenal ulcers. An insufficient number of therapeutic procedures is available for adequate fellow training requiring supplemental simulator and hands-on animal model, or adult endoscopy unit training.

 When assessing bleeding risk in patients with atrial fibrillation (AF), risk stratification is often based on the baseline risks. We aimed to investigate changes in bleeding risk factors and alterations in the HAS-BLED score in AF patients. We hypothesized that a follow-up HAS-BLED score and the 'delta HAS-BLED score' (reflecting the change in score between baseline and follow-up) would be more predictive of major bleeding, when compared with baseline HAS-BLED score.  A total of 19,566 AF patients receiving warfarin and baseline HAS-BLED score ≤2 were studied. After a follow-up of 93,783 person-years, 3,032 major bleeds were observed. The accuracies of baseline, follow-up, and delta HAS-BLED scores as well as cumulative numbers of baseline modifiable bleeding risk factors, in predicting subsequent major bleeding, were analysed and compared. The mean baseline HAS-BLED score was 1.43 which increased to 2.45 with a mean 'delta HAS-BLED score' of 1.03. The HAS-BLED score remained unchanged in 38.2% of patients. Of those patients experiencing major bleeding, 76.6% had a 'delta HAS-BLED' score ≥1, compared with only 59.0% in patients without major bleeding ( p  < 0.001). For prediction of major bleeding, AUC was significantly higher for the follow-up HAS-BLED (0.63) or delta HAS-BLED (0.62) scores, compared with baseline HAS-BLED score (0.54). The number of baseline modifiable risk factors was non-significantly predictive of major bleeding (AUC = 0.49).  In this 'real-world' nationwide AF cohort, follow-up HAS-BLED or 'delta HAS-BLED score' was more predictive of major bleeding compared with baseline HAS-BLED or the simple determination of 'modifiable bleeding risk factors'. Bleeding risk in AF is a dynamic process and use of the HAS-BLED score should be to 'flag up' patients potentially at risk for more regular review and follow-up, and to address the modifiable bleeding risk factors during follow-up visits.

Endoscopic band ligation is the treatment of choice for bleeding esophageal varices. However it is not clear if this procedure is associated with less early and late mortality than sclerotherapy. To assess rates of re-bleeding and mortality in cohorts of patients with bleeding esophageal varices treated with endoscopic injection or band ligation. Analysis of medical records and endoscopy reports of two cohorts of patients with bleeding esophageal varices, treated between 1990 and 2010. Of these, 54 patients were treated with sclerotherapy and 90 patients with band ligation. A third cohort of 116 patients that did not require endoscopic treatment, was included. The mean analyzed follow up period was 2.5 years (range 1-16). Collection of data was retrospective for patients treated with sclerotherapy and prospective for patients treated with band ligation. Rates of re-bleeding and medium term mortality were assessed. During the month ensuing the first endoscopic treatment, re-bleeding was recorded in 39 and 72% of patients treated with band ligation and sclerotherapy, respectively (p < 0.01). The relative risk of bleeding after band ligation was 0.53 (95% confidence limits 0.390.73). Death rates until the end of follow up were 20 and 48% among patients with treated with band ligation and sclerotherapy, respectively (p < 0.01), with a relative risk of dying for patients subjected to band ligation of 0.41 (95% confidence limits 0.25-0.68). Band ligation was associated with lower rates of re-bleeding and mortality in these cohorts of patients.

Early management of vascular injury, starting at the field, is imperative for survival no less than any operative maneuver. Contemporary prehospital management of vascular trauma, including appropriate fluid and volume infusion, tourniquets, and hemostatic agents, has reversed the historically known limb hemorrhage as a leading cause of death. In this context, damage control (DC) surgery has evolved to DC resuscitation (DCR) as an overarching concept that draws together preoperative and operative interventions aiming at rapidly reducing bleeding from vascular disruption, optimizing oxygenation, and clinical outcomes. This review addresses contemporary DCR techniques from the prehospital to the surgical setting, focusing on civilian vascular injuries.

Endovascular interventions for traumatic portal venous hemorrhage complicated by portal hypertension

Life-threatening hemorrhage rarely occurs from the portal vein following blunt hepatic trauma. Traditionally, severe portal bleeding in this setting has been controlled by surgical techniques such as packing, ligation, and venorrhaphy. The presence of portal hypertension could potentially increase the amount of hemorrhage in the setting of blunt portal vein trauma making it more difficult to control. This case series describes the use of indirect carbon dioxide portography to identify portal hemorrhage. Furthermore, these cases illustrate attempted endovascular treatment utilizing a transjugular intrahepatic portosystemic shunt in one scenario and transmesocaval shunt coiling of a jejunal varix in the other.

Tracheostomy is a common surgical procedure performed in long-term ventilated patients in intensive care. Since the role of percutaneous dilatational tracheostomy (PDT) on Intensive Care Unit (ICU) has become steadily more important in the last few years, a prospective study was started to evaluate the economic efficiency and to show the minimization of the complication rate of this procedure. In 72 patients we performed PDT as a bedside procedure. Initially the thyroid gland and the subcutaneous vessels were studied by ultrasound in every patient. The puncture of the trachea, the dilatational procedure and the insertion of the tracheal cannula were executed under bronchoscopic monitoring. Finally, a bronchoscopic control view followed via the new cannula to detect intratracheal complications. Mechanical ventilation was maintained during the procedure and controlled by continuous pulse oximetry. According to prior ultrasound findings the place to puncture the trachea was changed in 24% of the patients, in one case tracheostomy was performed as an open conventional procedure. The following complications could be observed: one case involving perforation of a cartilaginous ring, one case with venous bleeding of a small subcutaneous vein and two cases with punctures of the bronchoscope. There were no cases of miscannulation, penetration of the posterior tracheal wall or major bleeding requiring intervention or conversion. The followup study revealed that there was no sign of further complications in any patient. In addition, cost analysis demonstrated that there was a significant economical advantage of PDT in comparison with open standard tracheostomy. Standardized ultrasonographically and bronchoscopically controlled PDT turns out to be a safe, simple and cost effective bedside procedure on ICU. Because of ultrasound examination performed before the procedure, and bronchoscopic surveillance during the procedure, safety of this procedure can be enhanced, thus minimizing the rate of complications.

Acute major gastrointestinal bleeding caused by hookworm infection in a patient on warfarin therapy: A case report.

The use of anticoagulants is a contributor to gastrointestinal (GI) bleeding. Most bleeding patients on anticoagulant therapy such as warfarin commonly have basic lesions existing in their GI mucosa. We report a case of major GI bleeding following the use of anticoagulants in a patient with hookworm infection. The patient was diagnosed with nephrotic syndrome with pulmonary embolism. He was treated with anticoagulants and suffered from acute major GI bleeding during the treatment. Capsule endoscopy revealed many hookworms in the lumen of jejunum where fresh blood was seen coming from the mucosa. The patient was successfully rescued and cured with albendazole. Latent hookworm infection can be a cause of massive small-bowel hemorrhage in patients on anticoagulant therapy and anthelmintic treatment is the key to stop bleeding.

Gastrointestinal hemorrhage is considered to be a severe complication of von Willebrand disease. The optimal therapy for acquired von Willebrand syndrome and severe gastrointestinal bleeding with hypertrophic cardiomyopathy is undefined. Seventy-seven patients (median age, 67 years; interquartile range [IQR], 56-75 years; 49% women) with hypertrophic cardiomyopathy underwent von Willebrand factor multimer testing and acquisition of bleeding history. Bleeding was detected in 27 (36%) (median age, 74 years; IQR 66-76 years; 74% women), 20 with gastrointestinal bleeding, including 11 women with transfusion dependence. In these 11 women, the median duration of transfusion dependency was 36 months (IQR 18-44 months), and the median number of transfusions required was 25 (IQR 20-38). Two patients had undergone bowel resection for bleeding, one of them twice. Seven patients showed angiodysplasia, and the remainder had no endoscopic lesion. Bleeding recurred after bowel surgery or endoscopic intervention and medical therapy for hypertrophic cardiomyopathy in 10 of 11 patients. Two patients had septal myectomy, and six patients underwent alcohol septal ablation. With the exception of one patient in whom a significant gradient persisted after septal ablation, after the periprocedural period, patients after septal reduction therapy remained free of recurrent bleeding and need for transfusions. Acquired von Willebrand syndrome is common in hypertrophic cardiomyopathy. Gastrointestinal bleeding often recurs after endoscopic therapy, but may be relieved by structural cardiac repair. © 2014 International Society on Thrombosis and Haemostasis.

Background: Abdominal trauma is a major public health problem for all nations and all socioeconomic strata. Aim: This study was designed to determine the incidence and patterns of abdominal injuries in trauma patients. Materials and Methods: We classified and identified the incidence and subtype of abdominal injuries and associated trauma, and identified variables related to morbidity and mortality. Results: Abdominal trauma was present in 248 of 300 cases; 172 patients with blunt abdominal trauma and 76 with penetrating. The most frequent type of abdominal trauma was blunt trauma; its most common cause was motor vehicle accident. Among patients with penetrating abdominal trauma, the most common cause was stabbing. Most abdominal trauma patients presented with other injuries, especially patients with blunt abdominal trauma. Mortality was higher among penetrating abdominal trauma patients. Conclusions: Type of abdominal trauma, associated injuries, and Revised Trauma Score are independent risk factors for mortality in abdominal trauma patients. PMID:22454826

Risk scores in patients with atrial fibrillation (AF) based on clinical factors alone generally have only modest predictive value for predicting high risk patients that sustain events. Biomarkers might be an attractive prognostic tool to improve bleeding risk prediction. The new ABC-Bleeding score performed better than HAS-BLED score in a clinical trial cohort but has not been externally validated. The aim of this study was to analyze the predictive performance of the ABC-Bleeding score compared to HAS-BLED score in an independent "real-world" anticoagulated AF patients with long-term follow-up. We enrolled 1,120 patients stable on vitamin K antagonist treatment. The HAS-BLED and ABC-Bleeding scores were quantified. Predictive values were compared by c-indexes, IDI, NRI, as well as decision curve analysis (DCA). Median HAS-BLED score was 2 (IQR 2-3) and median ABC-Bleeding was 16.5 (IQR 14.3-18.6). After 6.5 years of follow-up, 207 (2.84 %/year) patients had major bleeding events, of which 65 (0.89 %/year) had intracranial haemorrhage (ICH) and 85 (1.17 %/year) had gastrointestinal bleeding events (GIB). The c-index of HAS-BLED was significantly higher than ABC-Bleeding for major bleeding (0.583 vs 0.518; p=0.025), GIB (0.596 vs 0.519; p=0.017) and for the composite of ICH-GIB (0.593 vs 0.527; p=0.030). NRI showed a significant negative reclassification for major bleeding and for the composite of ICH-GIB with the ABC-Bleeding score compared to HAS-BLED. Using DCAs, the use of HAS-BLED score gave an approximate net benefit of 4 % over the ABC-Bleeding score. In conclusion, in the first "real-world" validation of the ABC-Bleeding score, HAS-BLED performed significantly better than the ABC-Bleeding score in predicting major bleeding, GIB and the composite of GIB and ICH.

Multinational Prospective Study of Patient-Reported Outcomes After Prostate Radiation Therapy: Detailed Assessment of Rectal Bleeding

Lee, Jae Y.; Daignault-Newton, Stephanie; Heath, Gerard

Purpose: The new short Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) patient-reported health-related quality of life (HRQOL) tool has removed the rectal bleeding question from the previous much longer version, EPIC-26. Herein, we assess the impact of losing the dedicated rectal bleeding question in 2 independent prospective multicenter cohorts. Methods and Materials: In a prospective multicenter test cohort (n=865), EPIC-26 patient-reported HRQOL data were collected for 2 years after treatment from patients treated with prostate radiation therapy from 2003 to 2011. A second prospective multicenter cohort (n=442) was used for independent validation. A repeated-effects model was used to predictmore » the change from baseline in bowel summary scores from longer EPIC instruments using the change in EPIC-CP bowel summary scores with and without rectal bleeding scores. Results: Two years after radiation therapy, 91% of patients were free of bleeding, and only 2.6% reported bothersome bleeding problems. Correlations between EPIC-26 and EPIC-CP bowel scores were very high (r{sup 2}=0.90-0.96) and were statistically improved with the addition of rectal bleeding information (r{sup 2}=0.94-0.98). Considering all patients, only 0.2% of patients in the test cohort and 0.7% in the validation cohort reported bothersome bleeding and had clinically relevant HRQOL changes missed with EPIC-CP. However, of the 2.6% (n=17) of men with bothersome rectal bleeding in the test cohort, EPIC-CP failed to capture 1 patient (6%) as experiencing meaningful declines in bowel HRQOL. Conclusions: Modern prostate radiation therapy results in exceptionally low rates of bothersome rectal bleeding, and <1% of patients experience bothersome bleeding and are not captured by EPIC-CP as having meaningful HRQOL declines after radiation therapy. However, in the small subset of patients with bothersome rectal bleeding, the longer EPIC-26 should strongly be considered, given its superior performance in this patient subset.« less

To evaluate the efficacy and clinical outcomes of transcatheter arterial embolization (TAE) for gastrointestinal (GI) bleeding from gastrointestinal stromal tumor (GIST). TAE was performed in 20 referred patients (male:female = 13:7; median age, 56.3 y) for GI bleeding from GISTs. The locations of GISTs were assessed using contrast-enhanced computed tomography (CT) and catheter angiography. The technical and clinical success of TAE and clinical outcomes including procedure-related complications, recurrent bleeding, 30-day and overall mortality, and cumulative survival were evaluated. The sites of GIST-related bleeding or tumor staining were the jejunum (n = 9), stomach (n = 5), ileum (n = 3), duodenum (n = 2), and jejunum and colon (n = 1). Angiography showed bleeding from GIST in 5 patients, and tumor staining was noted in only 15 patients. TAE was performed for patients with and without contrast medium extravasation on angiography. Technical and clinical success rates of TAE were 95% (19 of 20 patients) and 90% (18 of 20 patients), respectively. Recurrent bleeding was noted in 1 patient. There were no procedure-related complications. In 15 patients, surgical resection of the tumors was performed after TAE. The 30-day and overall mortality rates were 10% (2 of 20 patients) and 30% (6 of 20 patients), respectively. TAE is a safe and effective method for controlling GI bleeding from the GIST.

Venous thromboembolism (VTE) occurs most often during hospitalization for major surgery or trauma but may also occur up to several months after surgery. Since the potential for VTE exists in a range of clinical settings, an assessment of its impact on overall outcomes and costs to the patient and to the healthcare system is warranted. To evaluate the effects of VTE (deep vein thrombosis, pulmonary embolism, or both) occurring within the first 30 days of hospital discharge for total hip replacement (THR) or total knee replacement (TKR) surgery on inpatient costs, mortality, rehospitalization, and major bleeding within 1 year after initial hospitalization for THR or TKR surgery. The Medicare Provider Analysis and Review (MEDPAR) file for calendar years 2005-2007 provided hospital discharge abstracts for the fee-for-service, acute-care hospitalizations of all Medicare recipients. All patients included in the analysis underwent THR (n = 51,108) or TKR (n = 115,627). VTE events were diagnosed within the first 30 days and within 1 year post discharge. Propensity score matching was used to control for differences in baseline characteristics in patients with and without VTE events. Total cost was measured as Medicare cost plus beneficiary out-of-pocket cost. VTE occurred in 0.74% of patients undergoing THR. For patients with VTE versus no VTE, mortality was higher (2.9% vs 0.4%, P < 0.001) and rehospitalization within 1 year was more frequent (51.9% vs 22.4%, P < 0.001), as were complications such as bleeding (11.2% vs 2.7%, P < 0.001). Risk-adjusted Medicare cost and total healthcare cost, including beneficiary cost share in 1 year, were significantly higher for VTE patients versus patients with no VTE ($18,929 vs $3763, P < 0.001). VTE occurred in 0.70% of patients undergoing TKR. For patients with VTE versus no VTE, mortality was higher (2.5% vs 0.15%, P < 0.001), and rehospitalization within 1 year was more frequent (48.7% vs 20.7%, P < 0.001), as were complications such as bleeding (13.7% vs 2.1%, P < 0.001). For TKR surgery, risk-adjusted total healthcare cost, including beneficiary cost share in 1 year, was significantly different for VTE versus no VTE ($17,996 vs $4358, P < 0.001). Study limitations include a reliance on ICD-9-CM codes, which could be inaccurate, and the inability (1) to control for unmeasured confounders, such as surgeons' skills; (2) to include outpatient medical care costs; and (3) to ensure that all patients were enrolled continuously throughout the study period. VTE after THR or TKR is associated with higher mortality, rehospitalization, and bleeding within 1 year, compared with no VTE. Risk-adjusted total, Medicare, and beneficiary healthcare costs were significantly higher for both THR and TKR patients with VTE (P < 0.001).

The aim of this study is to evaluate the short and long-term results of percutaneous tracheostomy in patients with documented cervical spine fracture. Between June 2000 and September 2005, 38 consecutive percutaneous tracheostomy procedures were performed on multi-trauma patients with cervical spine fracture. Modified Griggs technique was employed at the bedside in the general intensive care department. Staff thoracic surgeons and anesthesiologists performed all procedures. Demographics, anatomical conditions, presence of co-morbidities and complication rates were recorded. The average operative time was 10 min (6-15). Two patients had minor complications. One patients had minor bleeding (50 cc) and one had mild cellulitis. Nine patients had severe paraparesis or paraplegia prior to the PCT procedure and 29 were without neurological damage. There was no PCT related neurological deterioration. Twenty-eight patients were discharged from the hospital, 21 were decannulated. The average follow-up period was 18 months (1-48). There was no delayed, procedure related, complication. These results demonstrate that percutaneous tracheostomy is feasible and safe in patients with cervical spine fracture with minimal short and long-term morbidity. We believe that percutaneous tracheostomy is the procedure of choice for patients with cervical spine fracture who need prolonged ventilatory support.

Perimesencephalic hemorrhage (PMH) is a type of subarachnoid hemorrhage with excellent long-term outcomes. Only 1 well-documented case of in-hospital rebleeding after PMH is described in the literature, which occurred after initiating antithrombotic treatment because of myocardial ischemia. We describe a patient with PMH without antithrombotic treatment who had 2 episodes of recurrent bleeding on the day of ictus. To validate the radiologic findings, we conducted a case-control study. Six neuroradiologists and 2 neuroradiology fellows performed a blinded assessment of serial unenhanced head computed tomography (CT) scans of 8 patients with a perimesencephalic bleeding pattern (1 index patient, 6 patients with PMH, 1 patient with perimesencephalic bleeding pattern and basilar artery aneurysm) to investigate a potential increase in amount of subarachnoid blood. A 56-year-old woman with a perimesencephalic bleeding pattern and negative CT angiography had 2 episodes after the onset headache with a sudden increase of the headache. Blinded assessment of serial head CT scans of 8 patients with a perimesencephalic bleeding pattern identified the patient who was clinically suspected to have 2 episodes of recurrent bleeding to have an increased amount of subarachnoid blood on 2 subsequent CT scans. Recurrent bleeding after PMH may also occur in patients not treated with antithrombotics. Even after early rebleeding, the prognosis of PMH is excellent. Copyright © 2017 Elsevier Inc.

To determine the incidence and severity of bleeding events requiring hospitalization among patients with atrial fibrillation (AF) receiving anticoagulants (dabigatran or warfarin) or antiplatelet agents (eg, aspirin and clopidogrel). This was a single-center, retrospective cohort study involving 1494 patients with AF hospitalized from November 1, 2010, to November 1, 2011, with prior warfarin, dabigatran, or antiplatelet therapy. Overall bleeding events in the dabigatran group compared to the warfarin group were 24% and 12%, respectively ( P = .004). Of these events, individually, there were no significant differences in major (56% vs 58%, P = .88), life-threatening (25% vs 36%, P = .38), or minor bleeding (44% vs 42%, P = .06). Gastrointestinal (GI) bleeding occurred more in the dabigatran group compared to the warfarin group ( P = .02). Intracranial bleeding occurred in 15% of patients in the warfarin group and did not occur at all in the dabigatran group. Warfarin patients had significantly more overall bleeding events compared to antiplatelet therapy ( P < .001), with an increasing trend seen in major bleeding ( P = .06). GI bleeding, however, favored the warfarin group over the antiplatelet group (48% vs 73%, P = .04). Anticoagulation with dabigatran was associated with an overall increased occurrence of bleeding requiring hospital admission compared to warfarin. GI bleeding was more prevalent with dabigatran and antiplatelets than with warfarin. There were more intracranial hemorrhages seen in the warfarin group.

There is limited understanding of the effects of bleeding episodes on the daily lives of patients with congenital hemophilia with inhibitors and their caregivers. This analysis of the Dosing Observational Study in Hemophilia examined the impact of acute bleeding episodes on work, school, and family activities. Patients and caregivers participated in a diary study for 90 or more days or until patients experienced four bleeding episodes. All bleed treatments, interference with daily activities, and quality-of-life assessments were captured in daily records. Patients and caregivers reported planned workdays or school days eligible to be "lost" so as to differentiate from days lost because of disability or nonworking status, weekends, and vacations. Diaries were completed for 39 patients (18 adults and 21 children). Bleeding episodes that continued for 3 or more days (16.4%) accounted for most of the major changes to family plans. For the 38 patients with bleeding episodes, 47% of 491 bleed days fell on planned workdays or school days; the remainder fell on weekends, holidays, or nonworkdays or non-school days and therefore did not count as "lost days." Patients reported a loss of productivity on a greater percentage of eligible bleed days than did caregivers (3.9% vs. 0.8%, respectively). Patients and caregivers reported 13.5%/9.3% fully missed and 3.5%/7.6% partially missed days. This study demonstrated that in hemophilia with inhibitors, bleeding episodes interfere with the daily activities of patients and their caregivers. Furthermore, documenting only lost days underestimated the impact of bleeding episodes because of the high percentage of days without planned work or school.

Acute gastrointestinal bleeding-massive acute bleeding from gastrointestinal section is one of the most frequent forms of acute abdomen. The mortality degree in emergency surgery is about 10%. It's very difficult to identify the place of bleeding and etiology. The important purpose of this research is to present the cases of acute gastrointestinal bleeding from the patients which were monitored and treated at The University Clinical Center of Kosova-Emergency Center in Pristina. These inquests included 137 patients with acute gastrointestinal bleeding who were treated in emergency center of The University Clinical Center in Pristina for the period from January 2005 until December 2006. From 137 patients with acute gastrointestinal bleeding 41% or 29% was female and 96% or 70.1% male. Following the sex we gained a high significant difference of statistics (p < 0.01). The gastrointestinal bleeding was two times more frequent in male than in female. Also in the age-group we had a high significant difference of statistics (p < 0.01) 63.5% of patients were over 55 years old. The mean age of patients with an acute gastrointestinal bleeding was 58.4 years SD 15.8 age. The mean age for female patients was 56.4 age SD 18.5 age. The patients with arterial systolic pressure under 100 mmHg have been classified as patients with hypovolemic shock. They participate with 17.5% in all prevalence of acute gastrointestinal bleeding. From the number of prevalence 2 {1.5%} patients have been diagnosed with peptic ulcer, 1 {0.7%} as gastric perforation and 1 {0.7%} with intestine ischemia. Abdominal Surgery and Intensive Care 2 or 1.5% died, 1 at intensive care unit and 1 at nephrology. As we know the severe condition of the patients with gastrointestinal bleeding and etiology it is very difficult to establish, we need to improve for the better conditions in our emergency center for treatment and initiation base of clinic criteria.

To assess rates of further bleeding, surgery and mortality in patients hospitalized owing to peptic ulcer bleeding. Consecutive patients hospitalized for peptic ulcer bleeding and treated with a proton pump inhibitor (PPI) (esomeprazole or pantoprazole) were identified retrospectively in 12 centers in Spain. Patients were included if they had high-risk stigmata (Forrest class Ia-IIb, underwent therapeutic endoscopy and received intravenous PPI ≥120 mg/day for ≥24 h) or low-risk stigmata (Forrest class IIc-III, underwent no therapeutic endoscopy and received intravenous or oral PPI [any dose]). Of 935 identified patients, 58.3% had high-risk stigmata and 41.7% had low-risk stigmata. After endoscopy, 88.3% of high-risk patients and 22.1% of low-risk patients received intravenous PPI therapy at doses of at least 160 mg/day. Further bleeding within 72 h occurred in 9.4% and 2.1% of high- and low-risk patients, respectively (p < 0.001). Surgery to stop bleeding was required within 30 days in 3.5% and 0.8% of high- and low-risk patients, respectively (p = 0.007). Mortality at 30 days was similar in both groups (3.3% in high-risk and 2.3% in low-risk patients). Among patients hospitalized owing to peptic ulcer bleeding and treated with PPIs, patients with high-risk stigmata have a higher risk of further bleeding and surgery, but not of death, than those with low-risk stigmata.

Performance of risk scores for major bleeding in patients with atrial fibrillation and a previous transient ischemic attack or ischemic stroke is not well established. We aimed to validate risk scores for major bleeding in patients with atrial fibrillation treated with oral anticoagulants after cerebral ischemia and explore the net benefit of oral anticoagulants among bleeding risk categories. We analyzed 3623 patients with a history of transient ischemic attack or stroke included in the RE-LY trial (Randomized Evaluation of Long-Term Anticoagulation Therapy). We assessed performance of HEMORR 2 HAGES (hepatic or renal disease, ethanol abuse, malignancy, older age, reduced platelet count or function, hypertension [uncontrolled], anemia, genetic factors, excessive fall risk, and stroke), Shireman, HAS-BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly), ATRIA (Anticoagulation and Risk Factors in Atrial Fibrillation), and ORBIT scores (older age, reduced haemoglobin/haematocrit/history of anaemia, bleeding history, insufficient kidney function, and treatment with antiplatelet) with C statistics and calibration plots. Net benefit of oral anticoagulants was explored by comparing risk reduction in ischemic stroke with risk increase in major bleedings on warfarin. During 6922 person-years of follow-up, 266 patients experienced a major bleed (3.8 per 100 person-years). C statistics ranged from 0.62 (Shireman) to 0.67 (ATRIA). Calibration was poor for ATRIA and moderate for other models. The reduction in recurrent ischemic strokes on warfarin was larger than the increase in major bleeding risk, irrespective of bleeding risk category. Performance of prediction models for major bleeding in patients with cerebral ischemia and atrial fibrillation is modest but comparable with performance in patients with only atrial fibrillation. Bleeding risk scores cannot guide treatment decisions for oral anticoagulants but may still be useful to identify modifiable risk factors for bleeding. Clinical usefulness may be best for ORBIT, which is based on a limited number of easily obtainable variables and showed reasonable performance. © 2017 American Heart Association, Inc.

Acquired hemophilia A is a rare bleeding disorder caused by autoantibodies to coagulation FVIII. Bleeding episodes at presentation are spontaneous and severe in most cases. Optimal hemostatic therapy is controversial, and available data are from observational and retrospective studies only. The EACH2 registry, a multicenter, pan-European, Web-based database, reports current patient management. The aim was to assess the control of first bleeding episodes treated with a bypassing agent (rFVIIa or aPCC), FVIII, or DDAVP among 501 registered patients. Of 482 patients with one or more bleeding episodes, 144 (30%) received no treatment for bleeding; 31 were treated with symptomatic therapy only. Among 307 patients treated with a first-line hemostatic agent, 174 (56.7%) received rFVIIa, 63 (20.5%) aPCC, 56 (18.2%) FVIII, and 14 (4.6%) DDAVP. Bleeding was controlled in 269 of 338 (79.6%) patients treated with a first-line hemostatic agent or ancillary therapy alone. Propensity score matching was applied to allow unbiased comparison between treatment groups. Bleeding control was significantly higher in patients treated with bypassing agents versus FVIII/DDAVP (93.3% vs 68.3%; P = .003). Bleeding control was similar between rFVIIa and aPCC (93.0%; P = 1). Thrombotic events were reported in 3.6% of treated patients with a similar incidence between rFVIIa (2.9%) and aPCC (4.8%).

The endoscopic approach for pituitary tumors is a recent innovation and is said to reduce the nasal trauma associated with transnasal transsphenoidal surgery. The authors assessed the temporal changes in the rhinological symptoms following endoscopic transsphenoidal surgery for pituitary lesions, using the General Nasal Patient Inventory (GNPI). The GNPI was administered to 88 consecutive patients undergoing endoscopic transsphenoidal surgery at 3 time points (presurgery, 3-6 months postsurgery, and at final follow-up). The total GNPI score and the scores for the individual GNPI questions were calculated and differences between groups were assessed once before surgery, several months after surgery, and at final follow-up. Of a maximum possible score of 135, the mean GNPI score at 3-6 months postsurgery was only 12.9 ± 12 and was not significantly different from the preoperative score (10.4 ± 13) or final follow-up score (10.3 ± 10). Patients with functioning tumors had higher GNPI scores than those with nonfunctioning tumors for each of these time points (p < 0.05). Individually, a mild increase in symptom severity was seen for symptoms attributable to the nasal trauma of surgery, with partial recovery (nasal sores and bleeding) or complete recovery (nasal blockage, painful sinuses, and unpleasant nasal smell) by final follow-up (p < 0.05). Progressive improvements in symptom severity were seen for symptoms more attributable to tumor mass preoperatively (for example, headaches and painkiller use [p < 0.05]). In total, by final follow-up 8 patients (9%) required further treatment or advice for ongoing nasal symptoms. Endoscopic transsphenoidal surgery is a well-tolerated minimally invasive procedure for pituitary fossa lesions. Overall patient-assessed nasal symptoms do not change, but some individual symptoms may show a mild worsening or overall improvement.

Scores for cardio-embolic and bleeding risk in patients with atrial fibrillation are described in the literature. However, it is not clear how they co-classify elderly patients with multimorbidity, nor whether and how they affect the physician's decision on thromboprophylaxis. Four scores for cardio-embolic and bleeding risks were retrospectively calculated for ≥ 65 year old patients with atrial fibrillation enrolled in the REPOSI registry. The co-classification of patients according to risk categories based on different score combinations was described and the relationship between risk categories tested. The association between the antithrombotic therapy received and the scores was investigated by logistic regressions and CART analyses. At admission, among 543 patients the median scores (range) were: CHADS2 2 (0-6), CHA2DS2-VASc 4 (1-9), HEMORR2HAGES 3 (0-7), HAS-BLED 2 (1-6). Most of the patients were at high cardio-embolic/high-intermediate bleeding risk (70.5% combining CHADS2 and HEMORR2HAGES, 98.3% combining CHA2DS2-VASc and HAS-BLED). 50-60% of patients were classified in a cardio-embolic risk category higher than the bleeding risk category. In univariate and multivariable analyses, a higher bleeding score was negatively associated with warfarin prescription, and positively associated with aspirin prescription. The cardio-embolic scores were associated with the therapeutic choice only after adjusting for bleeding score or age. REPOSI patients represented a population at high cardio-embolic and bleeding risks, but most of them were classified by the scores as having a higher cardio-embolic than bleeding risk. Yet, prescription and type of antithrombotic therapy appeared to be primarily dictated by the bleeding risk. © 2013.

Clinical trial data suggest that dabigatran and warfarin have similar rates of major bleeding but higher rates of gastrointestinal bleeding. These findings have not been evaluated outside of a clinical trial. We evaluated the relative risks of any, gastrointestinal, intracranial, and other bleeding for Veterans Affairs patients who switched to dabigatran after at least 6 months on warfarin, compared with patients who continued on warfarin. We used national Veterans Affairs administrative encounter and pharmacy data from fiscal years 2010-2012 to identify 85,344 patients with atrial fibrillation who had been taking warfarin for at least 180 days before June 2011, of whom 1394 (1.7%) received dabigatran (150 mg) during the next 15 months. Dates of the first occurrence of each type of bleed and dates of death from June 2011 to September 2012 were determined. Baseline and time-dependent patient characteristics were identified, including comorbid conditions, stroke and bleeding risk scores, and time in therapeutic range for international normalized ratios. Marginal structural models were used to address selection bias in the longitudinal observational data. Weighted logistic regression models were fit using generalized estimating equations and reflected baseline and time-dependent covariates and weekly indicators of anticoagulant type (warfarin or dabigatran). Compared with patients who never used dabigatran, patients who used dabigatran at least once were younger, were more likely to be white, had lower international normalized ratio time in therapeutic range on warfarin, had lower stroke risk scores, and had similar bleeding risk scores. Overall, 10,734 patients experienced bleeding events, including 131 events after dabigatran use. The risk-adjusted rate of any bleeding was higher with dabigatran compared with warfarin, which was largely driven by a 54% higher risk of gastrointestinal bleeding with dabigatran. Rates of intracranial, other bleeding, and death were similar for dabigatran and warfarin. Dabigatran may increase the likelihood of gastrointestinal bleeds. Published by Elsevier Inc.

Periprocedural bleeding events are common after percutaneous coronary intervention. We evaluated the association of periprocedural bleeding events with thrombogenicity, which was measured quantitatively by the Total Thrombus-formation Analysis System equipped with microchips and thrombogenic surfaces (collagen, platelet chip [PL]; collagen plus tissue factor, atheroma chip [AR]). Between August 2013 and March 2016, 313 consecutive patients with coronary artery disease undergoing elective percutaneous coronary intervention were enrolled. They were divided into those with or without periprocedural bleeding events. We determined the bleeding events as composites of major bleeding events defined by the International Society on Thrombosis and Hemostasis and minor bleeding events (eg, minor hematoma, arteriovenous shunt and pseudoaneurysm). Blood samples obtained at percutaneous coronary intervention were analyzed for thrombus formation area under the curve (PL 24 -AUC 10 for PL chip; AR 10 -AUC 30 for AR chip) by the Total Thrombus-formation Analysis System and P2Y12 reaction unit by the VerifyNow system. Periprocedural bleeding events occurred in 37 patients. PL 24 -AUC 10 levels were significantly lower in patients with such events than those without ( P =0.002). Multiple logistic regression analyses showed association between low PL 24 -AUC 10 levels and periprocedural bleeding events (odds ratio, 2.71 [1.22-5.99]; P =0.01) and association between PL 24 -AUC 10 and periprocedural bleeding events in 176 patients of the femoral approach group (odds ratio, 2.88 [1.11-7.49]; P =0.03). However, PL 24 -AUC 10 levels in 127 patients of the radial approach group were not significantly different in patients with or without periprocedural bleeding events. PL 24 -AUC 10 measured by the Total Thrombus-formation Analysis System is a potentially useful predictor of periprocedural bleeding events in coronary artery disease patients undergoing elective percutaneous coronary intervention. © 2017 The Authors.

The incidence of postprocedural bleeding in patients undergoing rubber band ligation (RBL) for symptomatic internal hemorrhoids while taking clopidogrel bisulfate is unknown. To determine the postprocedural bleeding risk of RBL for patients taking clopidogrel compared with age- and sex-matched controls. This is a retrospective case-controlled cohort study analyzing data from 2005 to 2013 conducted at a single tertiary care academic center. The study included a total of 80 rubber bands placed on 41 patients taking clopidogrel bisulfate and 72 bands placed on 41 control patients not taking clopidogrel matched for age and sex. The 30-d rates of significant and insignificant bleeding events after RBL were recorded. A bleeding event was considered significant if the patient required admission to the hospital, transfusion of blood products, or additional procedures to stop the bleeding. Insignificant bleeding was defined as passage of blood or clots per rectum with spontaneous cessation and no need for additional intervention. There was no significant difference in the number of bleeding events per band placed in the clopidogrel group when compared with the control group (3.75% versus 2.78%, P = 0.7387). The rate of significant (2.5% versus 1.39%, P = 0.6244) and insignificant bleeding events (1.25% versus 1.39%, P = 0.9399) was also similar between the two groups. Two significant bleeding events occurred in the clopidogrel group requiring intervention: cauterization in one patient and colonoscopy and transfusion in the other. The risk of a bleeding complication after RBL for hemorrhoids does not appear to be increased in patients taking clopidogrel. Our results support the practice of continuing clopidogrel bisulfate in the periprocedural period as the associated risk of thrombosis is greater than the risk of bleeding.

A 74-year old female was transferred to our institution because of blunt chest trauma. Chest X-ray and computed tomography (CT) revealed right haemothorax and little pericardial effusion. She was taken to the operating theatre for emergent operation because of hypotension and massive bleeding from the right-sided chest tube. Cardiopulmonary resuscitation was started during surgical exploration. There were three 1-cm lacerations actively bleeding from the right atrium and inferior vena cava junction, which were repaired successfully. Furthermore, we identified a 10 cm laceration in the right-side pleuropericardium and a communication existing between the pericardial space and the right pleural space. PMID:24218497

Stomal variceal bleeding can develop in patients with underlying cirrhosis and portal hypertension. Most patients are best treated with transjugular intrahepatic portosystemic shunt (TIPS) creation because this addresses the underlying problem of portal hypertension. However, some patients are not good candidates for TIPS creation because they have end-stage liver disease or encephalopathy. We describe such a patient who presented with recurrent bleeding stomal varices, which was successfully treated with percutaneous coil embolization. The patient had bleeding-free survival for 1 month before death from unrelated causes.

Prediction models for intracranial hemorrhage or major bleeding in patients on antiplatelet therapy: a systematic review and external validation study.

ESSENTIALS: Prediction models may help to identify patients at high risk of bleeding on antiplatelet therapy. We identified existing prediction models for bleeding and validated them in patients with cerebral ischemia. Five prediction models were identified, all of which had some methodological shortcomings. Performance in patients with cerebral ischemia was poor. Background Antiplatelet therapy is widely used in secondary prevention after a transient ischemic attack (TIA) or ischemic stroke. Bleeding is the main adverse effect of antiplatelet therapy and is potentially life threatening. Identification of patients at increased risk of bleeding may help target antiplatelet therapy. This study sought to identify existing prediction models for intracranial hemorrhage or major bleeding in patients on antiplatelet therapy and evaluate their performance in patients with cerebral ischemia. We systematically searched PubMed and Embase for existing prediction models up to December 2014. The methodological quality of the included studies was assessed with the CHARMS checklist. Prediction models were externally validated in the European Stroke Prevention Study 2, comprising 6602 patients with a TIA or ischemic stroke. We assessed discrimination and calibration of included prediction models. Five prediction models were identified, of which two were developed in patients with previous cerebral ischemia. Three studies assessed major bleeding, one studied intracerebral hemorrhage and one gastrointestinal bleeding. None of the studies met all criteria of good quality. External validation showed poor discriminative performance, with c-statistics ranging from 0.53 to 0.64 and poor calibration. A limited number of prediction models is available that predict intracranial hemorrhage or major bleeding in patients on antiplatelet therapy. The methodological quality of the models varied, but was generally low. Predictive performance in patients with cerebral ischemia was poor. In order to reliably predict the risk of bleeding in patients with cerebral ischemia, development of a prediction model according to current methodological standards is needed. © 2015 International Society on Thrombosis and Haemostasis.

Self-Expandable Metal Stents for Persisting Esophageal Variceal Bleeding after Band Ligation or Injection-Therapy: A Retrospective Study.

Despite a pronounced reduction of lethality rates due to upper gastrointestinal bleeding, esophageal variceal bleeding remains a challenge for the endoscopist and still accounts for a mortality rate of up to 40% within the first 6 weeks. A relevant proportion of patients with esophageal variceal bleeding remains refractory to standard therapy, thus making a call for additional tools to achieve hemostasis. Self-expandable metal stents (SEMS) incorporate such a tool. We evaluated a total number of 582 patients admitted to our endoscopy unit with the diagnosis "gastrointestinal bleeding" according to our documentation software between 2011 and 2014. 82 patients suffered from esophageal variceal bleeding, out of which 11 cases were refractory to standard therapy leading to SEMS application. Patients with esophageal malignancy, fistula, or stricture and a non-esophageal variceal bleeding source were excluded from the analysis. A retrospective analysis reporting a series of clinically relevant parameters in combination with bleeding control rates and adverse events was performed. The initial bleeding control rate after SEMS application was 100%. Despite this success, we observed a 27% mortality rate within the first 42 days. All of these patients died due to non-directly hemorrhage-associated reasons. The majority of patients exhibited an extensive demand of medical care with prolonged hospital stay. Common complications were hepatic decompensation, pulmonary infection and decline of renal function. Interestingly, we found in 7 out of 11 patients (63.6%) stent dislocation at time of control endoscopy 24 h after hemostasis or at time of stent removal. The presence of hiatal hernia did not affect obviously stent dislocation rates. Refractory patients had significantly longer hospitalization times compared to non-refractory patients. Self-expandable metal stents for esophageal variceal bleeding seem to be safe and efficient after failed standard therapy. Stent migration appeared to be a common incident that did not lead to reactivation of bleeding in any of our patients. SEMS should be considered a reasonable treatment option for refractory esophageal variceal bleeding after treatment failure of ligature and sclerotherapy and non-availability of or contraindication for other measures (e.g. TIPS).

Factor V deficiency (FVD) is a rare bleeding disorder (RBD) mostly present in regions with a high rate of consanguinity. FVD after FXIII deficiency is the next more prevalent RBD in Sistan and Baluchistan (S&B) in southeastern Iran. The aim of this study was to evaluate the clinical manifestations and severity of bleeding diathesis in patients with FVD. This descriptive study was conducted on 23 patients with FVD in S&B province. FVD was diagnosed by clinical findings and routine laboratory tests. Bleeding diatheses were classified into three grades (I-III) depending on the severity of symptoms. The severity of bleeding episodes in our patients was compared with other RBDs. Based on residual plasma FV activity, 6 (26%), 16 (69.5%) and 1 (4.5%) patients had mild, moderate and severe factor deficiency, respectively. 24% of the patients had grade III life-threatening bleeding episodes which in comparison with FVII deficiency (17.4%) and FI deficiency (21%) had a higher incidence, and in comparison with FX deficiency (41.7%) and FXIII deficiency (63.1) had a lower incidence. Grade II and grade I bleeding diathesis were observed in 56.2 and 16.7% of the patients, respectively. FVD is the second most common type of RBD in S&B province and grade II bleeding episodes were the major bleeding presentation and observed in more than half of the patients. © 2014 S.

Several studies suggest that recombinant activated factor VII (rFVIIa) is more cost-effective than plasma-derived activated prothrombin complex concentrate (pd-aPCC) in haemophilia with inhibitors. However, most do not consider differences between treated patients. This study compared the pharmacoeconomics of rFVIIa versus pd-aPCC treatment of mild to moderate bleeds in inhibitor patients, taking co-variables into account. The HemoRec and HemIS registries capture exhaustive bleeding data in inhibitor patients in the Czech Republic. For each bleed, patient and bleed characteristics, treatment outcomes and bypassing agent use were retrospectively analysed, and direct costs of care per bleed calculated. Generalised Linear Model regression methods with cluster effect were employed to account for the possibility of several bleedings from the same patient. There were 108 and 53 mild to moderate bleeds in the rFVIIa and pd-aPCC groups, respectively. Although re-bleeding rates were similar in both groups, deeper analyses revealed significant differences in time to bleed resolution: 93.8% of bleeds treated with rFVIIa were resolved within ≤ 12 h, versus 60.4% with pd-aPCC (P < 0.001). Mean total cost/bleed was lower with rFVIIa (336,852 [median, 290,696] CZK; €12,760 [11,011]) than pd-aPCC (522,768 [341,310] CZK; €19,802 [12,928]) (P = 0.002). Results were maintained after controlling for potential co-variables (bleed nature, time to treatment, target joints). The lower total treatment costs per bleed with rFVIIa than pd-aPCC suggest that first-line rFVIIa is more cost-effective than pd-aPCC in mild to moderate bleeds. Time to bleed resolution was also significantly shorter with rFVIIa. These results were maintained when controlled for potential confounders. Copyright © 2012 Elsevier Ltd. All rights reserved.

Acute upper gastrointestinal bleeding (AUGIB) in cirrhotic patients occurs mainly from esophageal and gastric varices; however, quite a large number of cirrhotic patients bleed from other sources as well. The aim of the present work is to determine the prevalence of non-variceal UGIB as well as its different causes among the cirrhotic portal hypertensive patients in Nile Delta. Emergency upper gastrointestinal (UGI) endoscopy for AUGIB was done in 650 patients. Out of these patients, 550 (84.6%) patients who were proved to have cirrhosis were the subject of the present study. From all cirrhotic portal hypertensive patients, 415 (75.5%) bled from variceal sources (esophageal and gastric) while 135 (24.5%) of them bled from non-variceal sources. Among variceal sources of bleeding, esophageal varices were much more common than gastric varices. Peptic ulcer was the most common non-variceal source of bleeding. Non-variceal bleeding in cirrhosis was not frequent, and sources included peptic ulcer, portal hypertensive gastropathy, and erosive disease of the stomach and duodenum.

Upper gastrointestinal (GI) bleeding remains a commonly encountered diagnosis for acute care surgeons. Initial stabilization and resuscitation of patients is imperative. Stable patients can have initiation of medical therapy and localization of the bleeding, whereas persistently unstable patients require emergent endoscopic or operative intervention. Minimally invasive techniques have surpassed surgery as the treatment of choice for most upper GI bleeding. Copyright © 2014 Elsevier Inc. All rights reserved.

Essentials Low-molecular-weight-heparins (LMWH) kinetics differ which may result in different bleeding risks. A cohort of 12 934 venous thrombosis patients on LMWH was followed until major bleeding. The absolute major bleeding risk was low among patients registered at the anticoagulation clinic. Once-daily dosing was associated with a lower bleeding risk as compared with twice-daily. Background Low-molecular-weight heparins (LMWHs) are considered members of a class of drugs with similar anticoagulant properties. However, pharmacodynamics and pharmacokinetics between LMWHs differ, which may result in different bleeding risks. As these agents are used by many patients, small differences may lead to a large effect on numbers of major bleeding events. Objectives To determine major bleeding risks for different LMWH agents and dosing schedules. Methods A cohort of acute venous thrombosis patients from four anticoagulation clinics who used an LMWH and a vitamin K antagonist were followed until they ceased LMWH treatment or until major bleeding. Exposures were classified according to different types of LMWHs and for b.i.d. and o.d. use. Cumulative incidences for major bleeding per 1000 patients and risk ratios were calculated and adjusted for study center. Results The study comprised 12 934 patients with a mean age of 59 years; 6218 (48%) were men. The cumulative incidence of major bleeding was 2.5 per 1000 patients (95% confidence interval [CI], 1.7-3.5). Enoxaparin b.i.d. or o.d. was associated with a relative bleeding risk of 1.7 (95% CI, 0.2-17.5) compared with nadroparin o.d. In addition, a nadroparin b.i.d. dosing schedule was associated with a 2.0-fold increased major bleeding risk (95% CI, 0.8-5.1) as compared with a nadroparin o.d. dosing schedule. Conclusions Absolute major bleeding rates were low for all LMWH agents and dosing schedules in a large unselected cohort. Nevertheless, twice-daily dosing with nadroparin appeared to be associated with an increased major bleeding risk as compared with once-daily dosing, as also suggested in a meta-analysis of controlled clinical trials. © 2017 International Society on Thrombosis and Haemostasis.

AIM: To determine the value of computed tomographic angiography (CTA) for diagnosis and therapeutic planning in lower gastrointestinal (GI) bleeding. METHODS: Sixty-three consecutive patients with acute lower GI bleeding underwent CTA before endovascular or surgical treatment. CTA was used to determine whether the lower GI bleeding was suitable for endovascular treatment, surgical resection, or conservative treatment in each patient. Treatment planning with CTA was compared with actual treatment decisions or endovascular or surgical treatment that had been carried out in each patient based on CTA findings. RESULTS: 64-row CTA detected active extravasation of contrast material in 57 patients and six patients had no demonstrable active bleeding, resulting in an accuracy of 90.5% in the detection of acute GI bleeding (57 of 63). In three of the six patients with no demonstrable active bleeding, active lower GI bleeding recurred within one week after CTA, and angiography revealed acute bleeding. The overall location-based accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for the detection of GI bleeding by 64-row CTA were 98.8% (249 of 252), 95.0% (57 of 60), 100% (192 of 192), 100% (57 of 57), and 98.5% (192 of 195), respectively. Treatment planning was correctly established on the basis of 64-row CTA with an accuracy, sensitivity, specificity, PPV and NPV of 98.4% (248 of 252), 93.3% (56 of 60), 100% (192 of 192), 100% (56 of 56), and 97.5% (192 of 196), respectively, in a location-based evaluation. CONCLUSION: 64-row CTA is safe and effective in making decisions regarding treatment, without performing digital subtraction angiography or surgery, in the majority of patients with lower GI bleeding.

Posterior epistaxis is a frequent emergency, and the key to efficient management is identification of the bleeding point. We performed a retrospective study of 318 patients with posterior epistaxis treated with endoscopic bipolar electrocautery during a 4-year period. Distribution of the bleeding sites was recorded. Patients with no definite bleeding sites in the first operation were assigned to Group A (n = 39) and Group B (n = 34). Patients in Group A were only observed in the ward. Patients in Group B were given prophylactic electrocoagulation at the common bleeding points. Of the 318 patients, bleeding sites were successfully identified and coagulated in 263 patients. All of them were located posteriorly, with 166 on the lateral nasal wall, 86 on the septum, and 11 on the anterior face of the sphenoid sinus. The rebleeding rate of Group B (8.8%) was lower than that of Group A (38.5%) (p < 0.01).

Patients with minor acute ischemic stroke or transient ischemic attack are at high risk for subsequent stroke, and more potent antiplatelet therapy in the acute setting is needed. However, the potential benefit of more intense antiplatelet therapy must be assessed in relation to the risk for major bleeding. The SOCRATES trial (Acute Stroke or Transient Ischemic Attack Treated With Aspirin or Ticagrelor and Patient Outcomes) was the first trial with ticagrelor in patients with acute ischemic stroke or transient ischemic attack in which the efficacy and safety of ticagrelor were compared with those of aspirin. The main safety objective was assessment of PLATO (Platelet Inhibition and Patient Outcomes)-defined major bleeds on treatment, with special focus on intracranial hemorrhage (ICrH). An independent adjudication committee blinded to study treatment classified bleeds according to the PLATO, TIMI (Thrombolysis in Myocardial Infarction), and GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definitions. The definitions of ICrH and major bleeding excluded cerebral microbleeds and asymptomatic hemorrhagic transformations of cerebral infarctions so that the definitions better discriminated important events in the acute stroke population. A total of 13 130 of 13 199 randomized patients received at least 1 dose of study drug and were included in the safety analysis set. PLATO major bleeds occurred in 31 patients (0.5%) on ticagrelor and 38 patients (0.6%) on aspirin (hazard ratio, 0.83; 95% confidence interval, 0.52-1.34). The most common locations of major bleeds were intracranial and gastrointestinal. ICrH was reported in 12 patients (0.2%) on ticagrelor and 18 patients (0.3%) on aspirin. Thirteen of all 30 ICrHs (4 on ticagrelor and 9 on aspirin) were hemorrhagic strokes, and 4 (2 in each group) were symptomatic hemorrhagic transformations of brain infarctions. The ICrHs were spontaneous in 6 and 13, traumatic in 3 and 3, and procedural in 3 and 2 patients on ticagrelor and aspirin, respectively. In total, 9 fatal bleeds occurred on ticagrelor and 4 on aspirin. The composite of ICrH or fatal bleeding included 15 patients on ticagrelor and 18 on aspirin. Independently of bleeding classification, PLATO, TIMI, or GUSTO, the relative difference between treatments for major/severe bleeds was similar. Nonmajor bleeds were more common on ticagrelor. Antiplatelet therapy with ticagrelor in patients with acute ischemic stroke or transient ischemic attack showed a bleeding profile similar to that of aspirin for major bleeds. There were few ICrHs.

Bleeding from esophageal varices is a significant factor in mortality of patients with terminal liver cirrhosis. This complication is a major health problem for recipients on the list for liver transplant. In that regard, studying predictors of variceal bleeding episode is very important. Also, it is important to find the best survival predictor among prognostic scores. The aim of the study was to compare validity of prognostic scores in assessment of survival in hospital-treated patients after bleeding from esophageal varices, and to compare validity of baseline Child-Turcotte-Pugh (CTP) and Modul for End-stage Liver Disease (MELD) scores with CTP creatinine modified (CTP-crea) I and II scores in assessment of survival in patients within a long-term follow-up period after the episode of bleeding from esophageal varices. The study included a total of 126 patients suffering from terminal liver cirrhosis submited to testing CTP score score I and II, MELD score, MELD Na score, integrated MELD score, MELD sodium (MESO) index, United Kingdom Model for End-Stage Liver Disease (UKELD) score and updated MELD score. Patients with bleeding from esophageal varices most often had CTP score rank C (46,9%). CTP score rank B had 37.5% patients, while the smallest percentage of patients had CTP rank A, 15.6% of them. Patients who have values of CTP score higher than 10.50 and bleeding from esophagus, have 3.2 times higher chance for death outcome compared to other patients. Patients who have values of CTP-crea I score higher than 10.50 and bleeding from esophagus, have 3.1 times higher chance for death out-come than other patients. Patients who have values of CTP-crea II score higher than 11.50 and bleeding from esophagus, have 3,7 times higher chance for death outcome compared to other patients. Survival of patients with bleeding from esophageal varices in the short-term follow up can be predicted by following CTP score and creatinine modified CTP scores. Patients with bleeding from esophageal varices who have CTP score and CTP-crea I score higher than 10.5 and CTP-crea II score higher than 11.5, have statistically significantly higher risk from mortality within one-month follow-up compared to patients with bleeding from esophageal varices who have lower numerical values of scores of the CTP group.

PURPOSE We aimed to compare clinical outcomes and early adverse events of operative management (OM), nonoperative management (NOM), and NOM with splenic artery embolization (SAE) in blunt splenic injury (BSI) and identify the prognostic factors. METHODS Medical records of 136 consecutive patients with BSI admitted to a trauma center from 2005 to 2010 were retrospectively reviewed. Patients were separated into three groups: OM, NOM, and SAE. We focused on associated injuries and early adverse events. Multivariate analysis was performed on 23 prognostic factors to find predictors. RESULTS The total survival rate was 97.1%, with four deaths all occurred in the OM group. The spleen salvage rate was 91% in NOM and SAE. At least one adverse event was observed in 32.8%, 62%, and 96% of patients in NOM, SAE, and OM groups, respectively (P < 0.001). We found significantly more deaths, infectious complications, pleural drainage, acute renal failures, and pancreatitis in OM and more pseudocysts in SAE. Six prognostic factors were statistically significant for one or more adverse events: simplified acute physiology score 2 ≥25 for almost all adverse events, age ≥50 years for acute respiratory syndrome, limb fracture for secondary bleeding, thoracic injury for pleural drainage, and at least one associated injury for pseudocyst. Adverse events were not related to the type of BSI management. CONCLUSION Patients with BSI present worse outcome and more adverse events in OM, but this is related to the severity of injury. The main predictor of adverse events remains the severity of injury. PMID:26081719

Pre-endoscopic triage of patients who require an early upper endoscopy can improve management of patients with non-variceal upper gastrointestinal bleeding. To validate a new simplified clinical score (T-score) to assess the need of an early upper endoscopy in non variceal bleeding patients. Secondary outcomes were re-bleeding rate, 30-day bleeding-related mortality. In this prospective, multicentre study patients with bleeding who underwent upper endoscopy were enrolled. The accuracy for high risk endoscopic stigmata of the T-score was compared with that of the Glasgow Blatchford risk score. Overall, 602 patients underwent early upper endoscopy, and 472 presented with non-variceal bleeding. High risk endoscopic stigmata were detected in 145 (30.7%) cases. T-score sensitivity and specificity for high risk endoscopic stigmata and bleeding-related mortality was 96% and 30%, and 80% and 71%, respectively. No statistically difference in predicting high risk endoscopic stigmata between T-score and Glasgow Blatchford risk score was observed (ROC curve: 0.72 vs. 0.69, p=0.11). The two scores were also similar in predicting re-bleeding (ROC curve: 0.64 vs. 0.63, p=0.4) and 30-day bleeding-related mortality (ROC curve: 0.78 vs. 0.76, p=0.3). The T-score appeared to predict high risk endoscopic stigmata, re-bleeding and mortality with similar accuracy to Glasgow Blatchford risk score. Such a score may be helpful for the prediction of high-risk patients who need a very early therapeutic endoscopy. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

We need to include bystander first aid in trauma research.

The chain of trauma survival is a concept that originated in the area of out-of-hospital cardiac arrest (OHCA) and was adapted to the treatment of trauma. In out-of-hospital cardiac arrest research into bystander first aid has resulted in improved outcome. Whereas, in trauma research the first link of the chain of survival is almost ignored. In OHCA, cardiopulmonary resuscitation (CPR) from bystanders has been subject of a vast amount of research, as well as measures and programs to raise the rate of bystander CPR to cardiac arrest victims. These efforts have resulted in improved survival. The research effort has been well grounded in the research community, as demonstrated by its natural inclusion in the uniform reporting template (Utstein) for the treatment of OHCA. In trauma the bystander may contribute by providing an open airway, staunch bleedings, or prevent hypothermia. In trauma however, while the chain of survival has been adopted along with it distinct links, including bystander first aid, the consensus-based uniform reporting template for trauma (the Utstein template) does not include the bystander first aid efforts. There is extremely little research on what first aid measures bystanders provide to trauma victims, and on what impact such measures have on outcome. An important step to improve research on bystander first aid in trauma would be to include this as part of the uniform reporting template for trauma CONCLUSION: The lack of research on bystander first aid makes the first link in the trauma chain of survival the weakest link. We, the trauma research community, should either improve our research and knowledge in this area, or remove the link from the chain of survival.

Ximelagatran is a novel direct thrombin inhibitor that can be administered as a fixed oral dose, without the need for anticoagulant monitoring. We undertook a pooled analysis of 7329 patients with nonvalvular atrial fibrillation from the Stroke Prevention Using Oral Thrombin Inhibitor in Atrial Fibrillation III and V trials to compare bleeding outcomes in patients who received ximelagatran, 36 mg twice daily, or warfarin sodium (target international normalized ratio, 2.0-3.0). We determined annual risk of bleeding (any, major), case-fatality rate, time course and anatomic sites of major bleeding, and risk factors for major bleeding with ximelagatran and warfarin treatment. Annual incidence of any bleeding was 31.75% with ximelagatran and 38.82% with warfarin (relative risk reduction, 18.2%; 95% confidence interval [CI], 13.0-23.1; P<.001). Annual incidence of major bleeding was 2.01% with ximelagatran and 2.68% with warfarin (relative risk reduction, 25.1%; 95% CI, 3.2-42.1; P = .03). Case-fatality rate of bleeding was comparable in ximelagatran- and warfarin-treated patients (8.16% vs 8.09%; P = .98). Cumulative incidence of major bleeding was higher with warfarin than ximelagatran after 24 months of treatment (4.7% vs 3.7%; P = .04). Anatomic sites of bleeding were comparable with both treatments. Risk factors for bleeding with ximelagatran were as follows (hazard ratios and 95% CIs in parentheses): diabetes mellitus (1.81; 1.19-2.77; P = .006), previous stroke or transient ischemic attack (1.78; 1.16-2.73; P = .008), age 75 years or greater (1.70; 1.33-2.18; P<.001), and aspirin use (1.68; 1.08-2.59; P = .02). Risk factors for bleeding in warfarin-treated patients were previous liver disease (4.88; 1.55-15.39; P = .007); aspirin use (2.41; 1.69-3.43; P<.001); and age 75 years or greater (1.26; 1.03-1.52; P = .02). Treatment with ximelagatran, 36 mg twice daily, is associated with a lower risk of bleeding than warfarin in patients with nonvalvular atrial fibrillation. Aspirin use and increasing age were associated with an increased risk of bleeding in ximelagatran- and warfarin-treated patients.

Reversal of Direct Oral Anticoagulants: Current Status and Future Directions.

PubMed

Weitz, Jeffrey I

2017-02-01

Direct oral anticoagulants (DOACs) are increasingly used for prevention and treatment of venous thromboembolism and for prevention of stroke in patients with nonvalvular atrial fibrillation. In phase III clinical trials that included more than 100,000 patients, the DOACs were at least as effective as vitamin K antagonists (VKAs) and were associated with less serious bleeding, particularly less intracranial bleeding. Real-world evidence supports these outcomes. Despite this, some physicians and patients are concerned about serious bleeding or emergencies unless specific reversal agents for the DOACs are available. However, in clinical trials performed without reversal agents, the outcome of major bleeds was similar or better in patients receiving DOACs than in those taking VKAs. Because of their short half-lives, supportive measures are sufficient to manage most bleeds in patients receiving DOACs. Anticoagulant reversal should only be considered with life-threatening bleeds, with bleeds that fail to respond to usual measures and in patients requiring urgent surgery. Idarucizumab is licensed for dabigatran reversal and andexanet alfa is likely to be soon licensed for reversal of rivaroxaban, apixaban, and edoxaban. To ensure responsible use of these agents, every hospital needs a bleeding management algorithm that identifies patients eligible for reversal and outlines appropriate dosing regimens.

Abstract Intramural duodenal hematoma (IDH) is a rare complication in endoscopic management of ulcer hemorrhage. Usually noted in cases of blunt abdominal trauma, non-traumatic IDHs have been reported in individuals on anticoagulation, with blood disorders, pancreatic diseases and in endoscopic procedures such as biopsy, sclerotherapy and argon plasma coagulation. Patients may be asymptomatic or present with acute blood loss anemia, abdominal pain or vomiting. We report a case of an 83-year-old man with melena and syncope who underwent endoscopy for bleeding ulcer control and subsequently developed acute pancreatitis due to an acute IDH. Computed tomography (CT) scan confirms the diagnosis. Most cases are conservatively managed however when unsuccessful, laparoscopic surgical drainage or ultrasound or CT guided drainage can be performed. PMID:29383264

Earlobe piercing is a common office room procedure done by a plastic surgeon. Various methods of ear piercing have been described. In this article, we describe a novel method of laser ear piercing using the diode laser. An 18-year-old female patient underwent an ear piercing using a diode laser with a power of 2.0 W in continuous mode after topical local anaesthetic and pre-cooling. The diode laser was fast, safe, easy to use and highly effective way of ear piercing. The advantages we noticed while using the diode laser over conventional methods were more precision, minimal trauma with less chances of hypertrophy and keloids, no bleeding with coagulation effect of laser, less time taken compared to conventional method and less chance of infection due to thermal heat effect of laser.

Current guidelines make no specific recommendations on the selection of direct oral anticoagulants for the prevention and treatment of venous thromboembolism in patients with end-stage renal disease (ESRD) receiving hemodialysis. Based on these guidelines, warfarin remains the anticoagulant of choice in these patients. To compare bleeding rates in patients receiving apixaban or warfarin with ESRD undergoing chronic hemodialysis. This was a single-center, retrospective, institutional review board-approved cohort analysis. Patients with ESRD undergoing chronic hemodialysis and receiving anticoagulation therapy with either apixaban or warfarin were included in this study. All data were collected from paper charts and electronic medical records and included documentation of bleeding events and related interventions. The primary outcome of this study was clinically relevant major bleeding events. Secondary outcomes included clinically relevant nonmajor bleeding events and minor bleeding events. A total of 160 patients were included in this study (warfarin group, n = 120; apixaban group, n = 40). There were 7 major bleeding events in the warfarin group compared with zero in the apixaban group ( P = 0.34). There were similar rates of clinically relevant nonmajor bleeding events (12.5% vs 5.8%, P = 0.17) and minor bleeding (2.5% vs 2.5%, P = 0.74) events in patients receiving apixaban and warfarin. There were no observed differences in bleeding rates in patients receiving apixaban compared with those receiving warfarin. Apixaban may be a cautious consideration in hemodialysis patients until there is further insight into the effect of subsequent, multiple doses on drug accumulation and clinical outcomes.

The bleeding phenotype has been suggested to differ between haemophilia A and B. More knowledge on the bleeding phenotype at initiation of treatment is important to optimize patient care. The aim of this study was to investigate the severity of the bleeding phenotype and the variation in bleeding in children with severe or moderate haemophilia A and B. Consecutive, previously untreated patients with severe or moderate haemophilia A and B (factor VIII or IX activity <0.01 or 0.01-0.05 IU mL(-1) respectively) born between January 1st 2000 and January 1st 2010 were included. Primary outcome was severity of bleeding tendency. Secondary outcome was variation in bleeding pattern. A total of 582 patients with severe haemophilia A and 76 with severe haemophilia B did not differ in age at first exposure to clotting factor (0.81 vs. 0.88 years, P = 0.20), age at first bleed (0.82 vs. 0.88 years, P = 0.36), and age at first joint bleed (1.18 vs. 1.20 years, P = 0.59). Patients with moderate haemophilia were older compared to patients with severe haemophilia. In patients with moderate haemophilia there were no clear differences between haemophilia A and B. Severity and variation in bleeding phenotype are similar during the early stage of treatment in patients with severe and moderate haemophilia A and B respectively. The findings imply that children with haemophilia B should be observed and treated as vigilantly as those with haemophilia A. © 2014 John Wiley & Sons Ltd.

Bleeding is a serious and frequent complication of peptic ulcer disease. Hepatic dysfunction can cause coagulopathy and increases the risk of peptic ulcer bleeding. However, whether chronic liver disease increases mortality after peptic ulcer bleeding remains unclear. To examine the prognostic impact of chronic liver disease on mortality after peptic ulcer bleeding. We used population-based medical registries to conduct a cohort study of all Danish residents hospitalised with incident peptic ulcer bleeding from 2004 through 2011. We identified patients diagnosed with liver cirrhosis or non-cirrhotic chronic liver disease before their admission for peptic ulcer bleeding. We then computed 90-day mortality after peptic ulcer bleeding based on the Kaplan-Meier method (1 - survival function) and used a Cox regression model to estimate mortality rate ratios (MRRs), controlling for potential confounders. We identified 21,359 patients hospitalised with peptic ulcer bleeding. Among these, 653 (3.1%) had a previous diagnosis of liver cirrhosis and 474 (2.2%) had a history of non-cirrhotic chronic liver disease. Patients with liver cirrhosis and non-cirrhotic chronic liver disease had a cumulative 90-day mortality of 25.3% and 20.7%, respectively, compared to 18.3% among patients without chronic liver disease. Liver cirrhosis was associated with an adjusted 90-day MRR of 2.38 (95% CI: 2.02-2.80), compared to 1.49 (95% CI: 1.22-1.83) among patients with non-cirrhotic chronic liver disease. Patients with chronic liver disease, particularly liver cirrhosis, are at increased risk of death within 90 days after hospitalisation for peptic ulcer bleeding compared to patients without chronic liver disease. © 2015 John Wiley & Sons Ltd.

Multi-detector-row computed tomography (MDCT) has been reported to be a potentially useful modality for detection of the bleeding origin in patients with acute upper massive gastrointestinal (GI) bleeding. The purpose of this study is to investigate the efficacy of MDCT as a routine method for detecting the origin of acute upper GI bleeding prior to urgent endoscopy. Five hundred seventy-seven patients with acute upper GI bleeding (514 nonvariceal patients, 63 variceal patients) who underwent urgent upper GI endoscopy were retrospectively analyzed. Patients were divided into three groups: enhanced MDCT, unenhanced MDCT, and no MDCT before endoscopy. The diagnostic accuracy of MDCT for detection of the bleeding origin was evaluated, and the average procedure times needed to endoscopically identify the bleeding origin were compared between groups. Diagnostic accuracy among endoscopists was 55.3% and 14.7% for the enhanced MDCT and unenhanced MDCT groups, respectively. Among nonvariceal patients, accuracy was 50.2% in the enhanced MDCT group, which was significantly better than that in the unenhanced MDCT group (16.5%). In variceal patients, accuracy was significantly better in the enhanced MDCT group (96.4%) than in the unenhanced MDCT group (0.0%). These accuracies were similar to those achieved by expert radiologists. The average procedure time to endoscopic detection of the bleeding origin in the enhanced MDCT group was significantly faster than that in the unenhanced MDCT and no-MDCT groups. Enhanced MDCT preceding urgent endoscopy may be an effective modality for the detection of bleeding origin in patients with acute upper GI bleeding. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Fat embolism (FE) is a consequence of skeletal trauma that occurs in more than 90% of cases of severe trauma. However, most of these emboli are clinically insignificant. We report the case of a 59-yr-old man with massive progressive fibrosis who died from widespread FE after a single-lung transplantation (SLT). The lung donor was a 22-yr-old woman who died from traumatic cerebral injury. She had sustained a closed fracture of the tibia, fibula and pelvis. The PaO(2)/FiO(2) before procurement was 452 mmHg. A left SLT using cardiopulmonary bypass was performed. In the immediate postoperative period, profound pulmonary edema in the transplanted lung developed, with overinflation of the native lung and systemic hypotension. Severe Primary Graft Dysfunction (PGD) was suspected and nitric oxide (NO) and independent lung ventilation (ILV) initiated. Over the next 24 h the patient's condition deteriorated and extracorporeal membrane oxygenation (ECMO) was initiated. The patient died 45 h after transplantation as cardiovascular and respiratory function continued to decline and massive thoracic bleeding secondary to coagulopathy appeared. Post-mortem examination revealed both massive FE in the non-transplanted donor lung and in the allograft lung. Only two previous cases of donor-acquired FE and PGD after lung transplantation (LT) have been reported. Occult pulmonary FE in a traumatized donor should be considered a cause of PGD.

Purpose: Colonoscopy is reported to be a safe procedure that is routinely performed for the diagnosis and treatment of colorectal diseases. Splenic rupture is considered to be a rare complication with high mortality and morbidity that requires immediate diagnosis and management. Nonoperative management (NOM), surgical treatment (ST), and, more recently, proximal splenic artery embolization (PSAE) have been proposed as treatment options. The goal of this study was to assess whether PSAE is safe even in high-grade ruptures. Methods: We report two rare cases of post colonoscopy splenic rupture. A systematic review of the literature from 2002 to 2010 (first reportedmore » case of PSAE) was performed and the three types of treatment compared. Results: All patients reviewed (77 of 77) presented with intraperitoneal hemorrhage due to isolated splenic trauma. Splenic rupture was high-grade in most patients when grading was possible. Six of 77 patients (7.8 %) were treated with PSAE, including the 2 cases reported herein. Fifty-seven patients (74 %) underwent ST. NOM was attempted first in 25 patients with a high failure rate (11 of 25 [44 %]) and requiring a salvage procedure, such as PSAE or ST. Previous surgery (31 of 59 patients), adhesions (10 of 13), diagnostic colonoscopies (49 of 71), previous biopsies or polypectomies (31 of 57) and female sex (56 of 77) were identified as risk factors. In contrast, splenomegaly (0 of 77 patients), medications that increase the risk of bleeding (13 of 30) and difficult colonoscopies (16 of 51) were not identified as risk factors. PSAE was safe and effective even in elderly patients with comorbidities and those taking medications that increase the risk of bleeding, and the length of the hospital stay was similar to that after ST. Conclusion: We propose a treatment algorithm based on clinical and radiological criteria. Because of the high failure rate after NOM, PSAE should be the treatment of choice to manage grade I through IV splenic ruptures after colonoscopy in hemodynamically stabilized patients.« less

Benefits and risks of antithrombotic agents remain unclear in the hemodialysis population. We aimed to determine variation in antithrombotic agent use, rates of major bleeding events, and to determine factors predictive of stroke and bleeding to allow for risk stratification, enabling more rational decisions about using antithrombotic agents. The sample included 48,144 patients in 12 countries in the Dialysis Outcomes and Practice Patterns Study Phase I–IV. Antithrombotic agents included oral anticoagulants (OAC), ASA and anti-platelet agents (APA). OAC prescription, comorbidities and vascular access were assessed at study entry; data on clinical events including hospitalization due to bleeding were collected every four months during follow-up. There was wide variation in OAC (0.3–18%), APA (3–25%) and ASA use (8–36%), and major bleeding rates (0.05–0.22 events/year) among countries. Rates of all-cause mortality, cardiovascular mortality, and bleeding events requiring hospitalization were elevated in patients prescribed OAC across adjusted models. The CHADS2 score predicted the risk of stroke in atrial fibrillation patients. Gastrointestinal bleeding in the past 12 months was highly predictive of major bleeding events; for patients with previous gastrointestinal bleeding, the rate of bleeding exceeded the rate of stroke by at least 2-fold across categories of CHADS2 score. Prescription of antithrombotic agents varied greatly. The CHADS2 score and a history of gastrointestinal bleeding were predictive of stroke and bleeding events, respectively, with bleeding rates substantially exceeding stroke rates in all groups including patients at high stroke risk. Appropriate risk stratification and a cautious approach should be considered before OAC use in the dialysis population. PMID:23677245

Screening laboratory studies for bleeding disorders are of little predictive value for operative bleeding risk in adults. Predicting perioperative bleeding in pediatric patients is particularly difficult as younger patients often have not had significant hemostatic challenges. This issue is distinctly important for high bleeding risk surgeries, such as major spinal procedures. The aim of this study was to determine if the score of a detailed bleeding questionnaire (BQ) correlated with surgical bleeding in pediatric patients undergoing major spinal surgery. A total of 220 consecutive pediatric patients (mean age 14.2years) undergoing major spinal surgery were administered the BQ preoperatively, as well as having routine screening laboratory studies (i.e., PT, aPTT, PFA) drawn. A retrospective analysis was conducted to determine if there was a correlation between either the results of the BQ and/or laboratory studies with operative outcomes. A BQ score>2 showed a strong positive correlation with intraoperative bleeding based on both univariate and multivariate analyses. In contrast, abnormalities in screening laboratory studies showed no significant correlation with operative bleeding outcomes. Relying on screening laboratory studies alone is inadequate. The BQ used here correlated with increased intraoperative hemorrhage, suggesting this tool may be useful for assessing pediatric surgical bleeding risk, and may also be useful in identifying a subset of patients with a very low bleeding risk that may not require laboratory screening.

This observational, retrospective cohort study assessed outcomes of the current management strategies for nonvariceal upper gastrointestinal bleeding in several European countries (Belgium, Greece, Italy, Norway, Portugal, Spain, and Turkey) (NCT00797641; ENERGIB). Turkey contributed 23 sites to this study. Adult patients (≥18 years old) consecutively admitted to hospital and who underwent endoscopy for overt non-variceal upper gastrointestinal bleeding (hematemesis, melena or hematochezia, with other clinical/laboratory evidence of acute upper GI blood loss) were included in the study. Data were collected from patient medical records regarding bleeding continuation, re-bleeding, pharmacological treatment, surgery, and mortality during a 30-day follow-up period. A total of 423 patients (67.4% men; mean age: 57.8 ± 18.9 years) were enrolled in the Turkish study centers, of whom 96.2% were admitted to hospital with acute non-variceal upper gastrointestinal bleeding. At admission, the most common symptom was melena (76.1%); 28.6% of patients were taking aspirin, 19.9% were on non-steroidal anti-inflammatory drugs, and 7.3% were on proton pump inhibitors. The most common diagnoses were duodenal (45.2%) and gastric (27.7%) ulcers and gastritis/gastric erosions (26.2%). Patients were most often managed in general medical wards (45.4%). A gastrointestinal team was in charge of treatment in 64.8% of cases. Therapeutic procedures were performed in 32.4% of patients during endoscopy. After the endoscopy, most patients (94.6%) received proton pump inhibitors. Mean (SD) hospital stay was 5.36 ± 4.91 days. The cumulative proportions of continued bleeding/re-bleeding, complications and mortality within 30 days of the non-variceal upper gastrointestinal bleeding episode were 9.0%, 5.7% and 2.8%, respectively. In the Turkish sub-group of patients, the significant risk factors for bleeding continuation or re-bleeding were age >65 years, presentation with hematemesis or shock/syncope, and the diagnosis of duodenal ulcer. The risk of clinical complications after non-variceal upper gastrointestinal bleeding was higher in female patients older than 65 years, in patients with comorbidities, and in patients presenting with shock/syncope, and also according to time to endoscopy. The use of aspirin, non-steroidal anti-inflammatory drugs or warfarin at baseline was negatively associated with the development of bleeding or clinical complications. The risk of death within 30 days after non-variceal upper gastrointestinal bleeding was significantly higher in patients older than 65 years and in those receiving transfusions other than intravenous fluid or red blood cells within 12 hours of presentation. According to the survey results, non-variceal upper gastrointestinal bleeding in Turkey varies from that in other European countries in a number of aspects. These differences could be associated with a younger population and Helicobacter pylori incidence. Despite the diminishing need for surgical intervention and mortality rates for non-variceal upper gastrointestinal bleeding, as is the case in other European countries, non-variceal upper gastrointestinal bleeding remains a serious problem.

Lower gastrointestinal bleeding is usually self-limiting in about 80% of cases; however, surgical treatment may be required in selected cases. Preoperative precise identification of the bleeding source is crucial for a successful outcome. To determine the most frequent diagnoses, as well as short and long-term results in a series of patients who underwent a surgical procedure for lower gastrointestinal bleeding. Retrospective analysis of 39 patients operated upon for lower gastrointestinal bleeding from 1979 through 1997 in a referral center. Demographic data, history, physical examination, laboratory tests, resuscitative measures, preoperative work-up for identification of bleeding source, definitive cause of bleeding, surgical procedure, operative morbidity and mortality, as well as long-term status and recurrence of bleeding were recorded. There were 54% women and 46% men. Mean age was 56 years (range, 15-92). Most patients presented hematochezia (69%). Colonoscopy was the most used diagnostic procedure (69%). The bleeding source was located in 90% of patients. Diverticular disease was the most frequent cause of bleeding. A segmental bowel resection was the treatment in 97% of cases. Morbidity was 23% with 18% of mortality. Recurrence occurred in 9% of survivors. Morbidity and mortality were high. Patients who require a surgical operation should be carefully selected and evaluated with a complete work-up to determine the site and cause of bleeding.

Immune thrombocytopenia (ITP) is a rare disorder characterized by low platelet counts and an increased tendency to bleed. The goal of ITP therapy is to treat or prevent bleeding. Actual rates of bleeding are unknown. Clinical trial data may not reflect real-world bleeding rates because of the inclusion of highly refractory patients and more frequent use of rescue therapy. We used administrative medical claims data in the US to examine the occurrence of bleeding-related episodes (BREs) - a composite end point including bleeding and/or rescue therapy use - in adults diagnosed with primary ITP (2008-2012). BRE rates were calculated overall and by ITP phase and splenectomy status. Patients were followed from ITP diagnosis until death, disenrollment from the health plan, or June 30, 2013, whichever came first. We identified 6,651 adults diagnosed with primary ITP over the study period (median age: 53 years; 59% female). During 13,064 patient-years of follow-up, 3,768 patients (57%) experienced ≥1 BRE (1.08 BREs per patient-year; 95% confidence interval: 1.06-1.10). The majority (58%) of BREs consisted of rescue therapy use only. Common bleeding types were gastrointestinal hemorrhage, hematuria, ecchymosis, and epistaxis. Intracranial hemorrhage was reported in 74 patients (1%). Just over 7% of patients underwent splenectomy. Newly diagnosed and splenectomized patients had elevated BRE rates. We provide current real-world estimates of BRE rates in adults with primary ITP. The majority of ITP patients experienced ≥1 BRE, and over half were defined by rescue therapy use alone. This demonstrates the importance of examining both bleeding and rescue therapy use to fully assess disease burden.

Vitamin K antagonists (VKAs) have been the standard of care for treatment of thromboembolic diseases. Target-specific oral anticoagulants (TSOACs) have been developed and found to be at least noninferior to VKAs with regard to efficacy, but the risk of bleeding with TSOACs remains controversial. We performed a systematic review and meta-analysis of phase-3 randomized controlled trials (RCTs) to assess the bleeding side effects of TSOACs compared with VKAs in patients with venous thromboembolism or atrial fibrillation. We searched MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials; conference abstracts; and www.clinicaltrials.gov with no language restriction. Two reviewers independently performed study selection, data extraction, and study quality assessment. Twelve RCTs involving 102 607 patients were retrieved. TSOACs significantly reduced the risk of overall major bleeding (relative risk [RR] 0.72, P < .01), fatal bleeding (RR 0.53, P < .01), intracranial bleeding (RR 0.43, P < .01), clinically relevant nonmajor bleeding (RR 0.78, P < .01), and total bleeding (RR 0.76, P < .01). There was no significant difference in major gastrointestinal bleeding between TSOACs and VKAs (RR 0.94, P = .62). When compared with VKAs, TSOACs are associated with less major bleeding, fatal bleeding, intracranial bleeding, clinically relevant nonmajor bleeding, and total bleeding. Additionally, TSOACs do not increase the risk of gastrointestinal bleeding. © 2014 by The American Society of Hematology.

Damage control is well established as a potentially life-saving procedure in a few selected critically injured patients. In these patients the 'lethal triad' of hypothermia, acidosis, and coagulopathy is presented as a vicious cycle that often can not be interrupted and which marks the limit of the patient's ability to cope with the physiological consequences of injury. The principles of damage control have led to improved survival and to stopped bleeding until the physiologic derangement has been restored and the patient could undergo a prolong operation for definitive repair. Although morbidity is remaining high, it is acceptable if it comes in exchange for improved survival. There are five critical decision-making stages of damage control: I, patient selection and decision to perform damage control; II, operation and intraoperative reassessment of laparotomy; III, resuscitation in the intensive care unit; IV, definitive procedures after returning to the operating room; and V, abdominal wall reconstruction. The purpose of this article is to review the physiology of the components of the 'lethal triad', the indication and principles of abdominal damage control of trauma patients, the reoperation time, and the pathophysiology of abdominal compartment syndrome.

Concerns have arisen regarding the use of retrievable inferior vena cava filters (rIVCFs) in trauma patients due to increasing reports of low retrieval rates. We hypothesized that complete follow-up with a dedicated trauma nurse practitioner would be associated with a higher rate of retrievability. This study was undertaken to determine the rate of retrievability of rIVCFs placed in a Canadian Lead Trauma Centre, and to compare the rate of retrievability in our trauma population to our non-trauma patients. We performed a retrospective cohort study of all patients with rIVCF placed between Jan 1 2000 and June 30 2014. Data were collected on demographics, indication for filter placement, retrieval status, and reasons for non-retrieval. Comparison was made between trauma patients and non-trauma patients. A total of 374 rIVCFs were placed (61 in trauma patients and 313 in non-trauma patients) and follow-up was complete for the entire cohort. Filter retrieval was achieved in 86.9 % of trauma patients. Reasons for non-retrieval were technical in two patients, and death before retrieval in six patients. Retrieval was successful in 48.9 % of non-trauma patients. This study demonstrates that rIVCFs can be successfully retrieved amongst trauma patients. We demonstrated a higher rate of successful retrieval amongst trauma patients than non-trauma patients in our institution. Careful patient follow-up may play a role in successful retrieval of rIVCFs.

Prophylactic platelet transfusions are administered to prevent bleeding in haemato-oncological patients. However, bleeding still occurs, despite these transfusions. This practice is costly and not without risk. Better predictors of bleeding are needed, and flow cytometric evaluation of platelet function might aid the clinician in identifying patients at risk of bleeding. This evaluation can be performed within the hour and is not hampered by low platelet count. Our objective was to assess a possible correlation between bleeding and platelet function in thrombocytopenic haemato-oncological patients. Inclusion was possible for admitted haemato-oncology patients aged 18 years and above. Furthermore, an expected need for platelet transfusions was necessary. Bleeding was graded according to the WHO bleeding scale. Platelet reactivity to stimulation by either adenosine diphosphate (ADP), cross-linked collagen-related peptide (CRP-xL), PAR1- or PAR4-activating peptide (AP) was measured using flow cytometry. A total of 114 evaluations were available from 21 consecutive patients. Platelet reactivity in response to stimulation by all four studied agonists was inversely correlated with significant bleeding. Odds ratios (OR) for bleeding were 0·28 for every unit increase in median fluorescence intensity (MFI) [95% confidence interval (CI) 0·11-0·73] for ADP; 0·59 [0·40-0·87] for CRP-xL; 0·59 [0·37-0·94] for PAR1-AP; and 0·43 [0·23-0·79] for PAR4-AP. The platelet count was not correlated with bleeding (OR 0·99 [0·96-1·02]). Agonist-induced platelet reactivity was significantly correlated to bleeding. Platelet function testing could provide a basis for a personalized transfusion regimen, in which platelet transfusions are limited to those at risk of bleeding. © 2017 International Society of Blood Transfusion.

Essential In patients on treatment with direct anticoagulants (DOACs) variation of renal function is common. The effect of variations of renal function over time on major bleeding is not well defined. Variation of renal function over time is an independent predictor of major bleeding. Identifying conditions associated with variation of renal function may increase safety of DOACs. Background Chronic kidney disease is a risk factor for major bleeding in patients with atrial fibrillation (AF) treated with warfarin. Objective To assess the effect of variations in renal function over time on the risk of major bleeding during treatment with direct oral anticoagulants (DOACs) in patients with non-valvular AF. Methods Consecutive AF patients were prospectively followed after they had received the first DOAC prescription. Estimated glomerular filtration rate (eGFR) was periodically assessed, and the incidence of major bleeding was recorded. A joint survival model was used to estimate the association between variation in eGFR and the risk of major bleeding. Results During a mean follow-up of 575 days, 44 major bleeds occurred in 449 patients (6.1% per patient-year). eGFR over time was inversely and independently associated with the risk of major bleeding; every 1 mL min -1 absolute decrease in eGFR was associated with a 2% increase in the risk of major bleeding (hazard ratio [HR] 1.02, 95% confidence interval [CI] 1.01-1.04). A similar effect of the variation in eGFR over time was observed on the risk of clinically relevant non-major bleeding (HR 1.02, 95% CI 1.01-1.03). Deterioration of renal function leading to a change in eGFR staging was associated with an increase in the risk of major bleeding (HR 2.43, 95% CI 1.33-4.45). Conclusions Variation in renal function over time is associated with the risk of major bleeding in AF patients treated with DOACs in real life. Identification of intervening clinical conditions associated with variation in renal function is essential to reduce the risk of major bleeding and to make DOAC treatment more safe. © 2018 International Society on Thrombosis and Haemostasis.

Use of oral anticoagulation therapy in patients with atrial fibrillation (AF) involves a trade-off between a reduced risk of ischemic stroke and an increased risk of bleeding events. Different anticoagulation therapies have different safety profiles and data on the societal costs of both ischemic stroke and bleeding events are necessary for assessing the cost-effectiveness and budgetary impact of different treatment options. To our knowledge, no previous studies have estimated the societal costs of bleeding events in patients with AF. The objective of this study was to estimate the 3-years societal costs of first-incident intracranial, gastrointestinal and other major bleeding events in Danish patients with AF. The study was an incidence-based cost-of-illness study carried out from a societal perspective and based on data from national Danish registries covering the period 2002-2012. Costs were estimated using a propensity score matching and multivariable regression analysis (first difference OLS) in a cohort design. Average 3-years societal costs attributable to intracranial, gastrointestinal and other major bleeding events were 27,627, 17,868, and 12,384 EUR per patient, respectively (2015 prices). Existing evidence shows that the corresponding costs of ischemic stroke were 24,084 EUR per patient (2012 prices). The average costs of bleeding events did not differ between patients with AF who were on oral anticoagulation therapy prior to the event and patients who were not. The societal costs attributable to major bleeding events in patients with AF are significant. Intracranial haemorrhages are most costly to society with average costs of similar magnitude as the costs of ischemic stroke. The average costs of gastrointestinal and other major bleeding events are lower than the costs of intracranial haemorrhages, but still substantial. Knowledge about the relative size of the costs of bleeding events compared to ischemic stroke in patients with AF constitutes valuable evidence for decisions-makers in Denmark as well as in other countries.

To identify the frequency and characteristics of bleeding complications during acute inpatient rehabilitation of hematologic malignancy patients with severe thrombocytopenia. Retrospective descriptive analysis. Comprehensive cancer center acute inpatient rehabilitation unit. Consecutive hematologic malignancy patients with a platelet count of less than or equal to 20,000/microliter (μL) on the day of acute inpatient rehabilitation admission from 1/1/2005 through 8/31/2016. Medical records were retrospectively analyzed for demographic, laboratory, and medical data. Patients were rehabilitated using the institutional exercise guidelines for thrombocytopenic patients. Bleeding events noted in the medical record. Out of 135 acute inpatient rehabilitation admissions, 133 unique patients were analyzed with a total of 851 inpatient rehabilitation days. The mean platelet count was 14,000/μL on the day of admission and 22,000/μL over the course of the rehabilitation admission. There were 252 days of inpatient rehabilitation where patients had less than 10,000/μL platelets. A total of 97 bleeding events were documented in 77/135 (57%) admissions. Of the 97 bleeding events, 72 (74%), 14 (14%), and 11 (11%) were considered to be of low, medium, and high severity, respectively. There were 4/97 (4%) bleeding events that were highly likely attributable to physical activity but only 1/4 was considered high severity. Bleeding rates were .09, .08, .17, and .37 for > 20,000, 15-20,000, 10-15,000, and < 10,000/μL mean platelet counts respectively (p = .003). Forty-four percent of patients were transferred back to the primary acute care service with infection being the most common reason for transfer. This study is the first to examine exercise-related bleeding complications during acute inpatient rehabilitation in severely thrombocytopenic hematologic cancer patients. Bleeding rates increased with lower platelet counts. However, using the exercise guidelines for severely thrombocytopenic patients, the risk of severe exercise-related bleeding events was low.

Balancing the risks for thromboembolism and postpolypectomy bleeding in patients requiring anticoagulation and antiplatelet agents is challenging. We investigated the incidence and risk factors for postpolypectomy bleeding on anticoagulation, including heparin bridge and other antithrombotic therapy. We performed a retrospective cohort and case control study at 2 tertiary-care medical centers from 2004 to 2012. Cases included male patients on antithrombotics with hematochezia after polypectomy. Nonbleeding controls were matched to cases 3 to 1 by antithrombotic type, study site, polypectomy technique, and year of procedure. Our outcomes were the incidence and risk factors for postpolypectomy bleeding. There were 59 cases and 174 matched controls. Postpolypectomy bleeding occurred in 14.9% on bridge anticoagulation. This was significantly higher than the overall incidence of bleeding on antithrombotics at 1.19% (95% confidence interval, 0.91%-1.54%) (59/4923). We identified similarly low rates of bleeding in patients taking warfarin (0.66%), clopidogrel (0.84%), and aspirin (0.92%). Patients who bled tended to have larger polyps (13.9 vs 7.3 mm; P < .001) and more polyps ≥2 cm (41% vs 10%; P < .001). Bleeding risk was increased with restarting antithrombotics within 1 week postpolypectomy (odds ratio [OR] 4.50; P < .001), having polyps ≥2 cm (OR 5.94; P < .001), performing right-sided cautery (OR 2.61; P = .004), and having multiple large polyps (OR 2.92; P = .001). Among patients on warfarin, the presence of bridge anticoagulation was an independent risk factor for postpolypectomy bleeding (OR 12.27; P = .0001). We conclude that bridge anticoagulation is associated with a high incidence of postpolypectomy bleeding and is an independent risk factor for hemorrhage compared with patients taking warfarin alone. A higher threshold to use bridge anticoagulation should be considered in patients with an elevated bleeding risk. Copyright © 2018. Published by Elsevier Inc.

Endoscopic variceal ligation (EVL) is widely used to prevent esophageal variceal bleeding in patients with advanced cirrhosis. However, the safety and efficacy of EVL in this setting have not been clearly established. This study included 300 adult patients with cirrhosis on our liver transplant waitlist who underwent upper gastrointestinal endoscopy. Esophageal varices deemed to be at high risk of bleeding were banded until eradication or transplantation. A retrospective review of patient notes and endoscopy databases was undertaken, and the number of banding episodes, complications, and patient outcomes were recorded. Forty-two of 300 patients presented with or had previous variceal bleeding prior to referral and were excluded from the analysis. Of the remaining 258 patients, 101 underwent a total of 259 banding episodes (2.6 per patient) with a median follow-up post-banding of 18.4 months per patient (a total of 150 patient years). Failed prophylaxis occurred in 2 patients (2%), and there were 3 episodes (1.2%) of acute hematemesis from band-induced ulceration. One patient (1%) had mild esophageal stricturing post-banding without dysphagia. Four of 36 patients (11%) previously found to have moderately sized or larger varices that were not banded presented with hematemesis due to variceal bleeding and were subsequently banded. None of the patients that received banding died because of bleeding or failed to receive a transplant as a result of banding complications. This study shows that in liver transplant candidates, EVL is highly effective in preventing first variceal bleed. Although banding carries a small risk of band-induced bleeding, this rate is low in comparison with the predicted rate of variceal bleeding in this population.

Gastrointestinal and abdominal bleeding can lead to life-threatening situations. Embolization is considered a feasible and safe treatment option. The relevance of surgery has thus diminished in the past. The aim of the present study was to evaluate the role of surgery in the management of patients after embolization. We performed a retrospective single-center analysis of outcomes after transarterial embolization of acute abdominal and gastrointestinal hemorrhage between January 2009 and December 2012 at the Sisters of Charity Hospital, Linz. Patients were divided into three groups, as follows: upper gastrointestinal bleeding (UGIB), lower gastrointestinal bleeding (LGIB), and abdominal hemorrhage. Fifty-four patients with 55 bleeding events were included. The bleeding source could be localized angiographically in 80 %, and the primary clinical success rate of embolization was 81.8 % (45/55 cases). Early recurrent bleeding (<30 days) occurred in 18.2 % (10/55) of the patients, and delayed recurrent hemorrhage (>30 days) developed in 3.6 % (2/55). The mean follow-up was 8.4 months, and data were available for 85.2 % (46/54) of the patients. Surgery after embolization was required in 20.4 % of these patients (11/54). Failure to localize the bleeding site was identified as predictive of recurrent bleeding (p = 0.009). More than one embolization effort increased the risk of complications (p = 0.02) and rebleeding (p = 0.07). Surgery still has an important role after embolization in patients with gastrointestinal and abdominal hemorrhage. One of five patients required surgery in cases of early and delayed rebleeding or because of ischemic complications (2/55 both had ischemic damage of the gallbladder) and bleeding consequences.

One Stage Emergency Pancreatoduodenectomy  for Isolated Injury to Pancreatic Head Following Blunt Abdominal Trauma: Case Report and Review of Literature.

Major pancreatic injury following blunt abdominal trauma by itself is a relatively rare occurrence, and in vast majority of cases (95%) it is associated with injury to adjacent major vessels and organs; thus making isolated major pancreatic injury even rarer. While most pancreatic injuries are managed by simple measures like debridement and drainage, complex proximal injury poses surgical challenge regarding surgical skill and judgement. Disproportionate approach at any stage of management can contribute  to high mortality and morbidity. Emergency pancreatoduodenectomy plays a limited but important role in managing serious trauma to proximal pancreas and duodenum. Author presents a case where isolated injury to head of pancreas required emergency pancreatoduodenectomy. After a bizarre road accident, a middle aged male underwent emergency laparotomy for intraperitoneal bleeding and during exploration a deep transverse laceration with ampullary disruption was found in the head of the organ. Duodenum in all its part was intact and there was no other injury. The nature and site of injury made emergency pancreatoduodenectomy the only viable option. Leaking pancreatojejunostomy enhances infective complications that lead to late mortality. To circumvent this problem there is enthusiasm for staged surgery with resection and tube pancreatostomy in first stage, leaving the difficult anastomosis for a later date, However, if the patient is haemodynamically stable and operated reasonably early, one stage pancreatoduodenectomy gives good result and avoids repeating surgery with inherent problems and reduces hospital stay. For successful management of pancreatic trauma it is essential to make early diagnosis of duct disruption, with sound application of operative skill and judgement by treating surgeon.

This case report is intended to inform acute care surgeons about treating rare horizontal laceration of the pancreas head caused by blunt trauma. A 57-year-old woman who sustained blunt abdominal trauma during a car crash was transported to the emergency center of our hospital with unstable vital signs due to hemorrhagic shock. Computed tomography showed transection of the pancreas head and massive intra-abdominal hemorrhage. She was referred for emergency surgery because of a transient response. Laparotomy at five hours after the accident initially revealed consistent massive bleeding from branches of the superior mesenteric artery and vein, which we resolved by suturing the vessels without damaging the main trunks. A horizontal laceration and complete transection of the pancreatic head were then confirmed but the main pancreatic duct remained intact. The lower part of the pancreatic head including the uncus with the attached part of the duodenum was resected, and the pancreatic stump remaining after transection was fixed by suturing. The jejunal limb was attached to the remnant duodenum by side-to-side functional anastomosis. Although gastric emptying was delayed for one month after surgery, the postoperative course was good and the patient recovered at three months thereafter. The embryonic border of pancreas head accompanied with pancreatic divisum was considered for this laceration without disruption of the main pancreatic duct. Blunt pancreatic trauma usually causes vertical transection and thus, horizontal transection is considered rare. The embryological anatomical border between the ventral and dorsal pancreas due to pancreatic divisum was supposed to be transected and therefore the main pancreatic duct was not damaged. Hemorrhagic shock and rare pancreatic head trauma were treated by appropriate intraoperative management. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

To evaluate massive transfusion protocol practices by trauma type at a level I trauma center. A retrospective analysis was performed on a sample of 76 trauma patients with MTP activation between March 2010 and January 2015 at a regional trauma center. Patient demographics, transfusion practices, and clinical outcomes were compared by type of trauma sustained. Penetrating trauma patients who required MTP activation were significantly younger, had lower injury severity score (ISS), higher probability of survival (POS), decreased mortality, and higher Glasgow Coma scale (GCS) compared to blunt trauma patients. Overall, the mortality rate was 38.16%. The most common injury sustained among blunt trauma patients was head injury (36.21%), whereas the majority of the penetrating trauma patients sustained abdominal injuries (55.56%). Although the admission coagulation parameters and timing of coagulopathy were not significantly different between the two groups of patients, a significantly higher proportion of penetrating trauma patients received high plasma content therapy relative to blunt trauma patients (p < 0.01). Despite the use of the same MTP for all injured patients requiring massive transfusion, significant differences existed between blunt trauma patients and penetrating trauma patients. These differences in transfusion characteristics and outcomes following MTP activation underscore the complexity of implementing MTPs and warrant vigilant transfusion practices to improve outcomes in trauma patients.

ObjectiveThis study was designed to evaluate the role of a negative computed tomography angiogram (CTA) in patients who present with gastrointestinal (GI) hemorrhage.MethodsA review of all patients who had CTAs for GI hemorrhage over an 8-year period from January 2005 to December 2012 was performed. Data for patient demographics, location of hemorrhage, hemodynamic stability, and details of angiograms and/or the embolization procedure were obtained from the CRIS/PACS database, interventional radiology database, secure electronic medical records, and patient’s clinical notes.ResultsA total of 180 patients had 202 CTAs during the 8-year period: 87 CTAs were performed for upper GI hemorrhage (18 positivemore » for active bleeding, 69 negative) and 115 for lower GI hemorrhage (37 positive for active bleeding, 78 negative); 58.7 % (37/63) of patients with upper GI bleed and 77.4 % (48/62) of patients with lower GI bleed who had an initial negative CTA did not rebleed without the need for radiological or surgical intervention. This difference was statistically significant (p = 0.04). The relative risk of rebleeding, following a negative CTA, in lower GI bleeding versus upper GI bleeding patients is 0.55 (95 % confidence interval 0.32–0.95).ConclusionsPatients with upper GI bleed who had negative CTAs usually require further intervention to stop the bleeding. In contrast, most patients presenting with lower GI hemorrhage who had a negative first CTA were less likely to rebleed.« less

Thromboembolism is rarely considered in discussions of the complications of blunt chest trauma. The few cases of thromboembolism that have been reported in this setting have occurred in association with significant myocardial damage. A previously fit 23 year old woman was admitted to the intensive care unit following a road traffic accident. A day later, left atrial thrombus was demonstrated by transoesophageal echocardiography in the absence of any other evidence of important myocardial injury. Anticoagulation with heparin was cautiously introduced in spite of her extensive injuries, and there were no consequent bleeding complications. At hospital discharge on day 18 she was entirely well. Full anticoagulation with warfarin was continued for a further eight weeks at which time follow up transoesophageal echocardiography showed complete resolution of the thrombus.
