    Femoral vein catheterization is an alternative method of obtaining central venous access. Placement of femoral venous catheters (FVCs) is possible in the majority of patients, suitable for most indications, and associated with a low complication rate during insertion. We wished to determine the incidence of infections or other complications resulting when parenteral nutrition was delivered through FVCs. Fifty-two patients were followed from a hospital-wide population including patients in the critical care units. Triple-lumen catheters were placed by using the sterile Seldinger technique, and sites were examined daily for inflammation. Bacteriologic surveillance was accomplished by submitting the catheter tip for semiquantitative cultures. If catheter line sepsis was suspected, blood samples for cultures were drawn through the catheter and peripherally. The rate of occurrence of colonized catheters was 9.6% (five of 52), and catheter sepsis was found in one case (1.9%). Other than inflammation at six (11.5%) of 52 catheter sites, noninfectious complications of FVCs were not found. On the basis of these findings, we consider FVC-delivered parenteral alimentation a safe and effective alternative to other forms of central venous access.

    The objective of this prospective observational study was to determine the influence of femoral and central internal jugular venous catheters on the incidence of catheter-related bacteremia (CRB). We included patients admitted to a 12-bed polyvalent medico-surgical intensive care unit over 4 years who received one or more femoral or central internal jugular venous catheters. We diagnosed 16 cases of CRB in 208 femoral catheters and 22 in 515 central internal jugular venous catheters. We found a higher incidence of CRB with femoral (9.52 per 1,000 catheter days) than with central internal jugular venous access (4.83 per 1,000 catheter days; risk ratio = 1.93; 95% confidence interval: 1.03-3.73; P = 0.04). Central internal jugular venous access could be considered a safer route of venous access than femoral access in minimizing the risk of central venous catheter-related bacteremia.

  5. Transpulmonary thermodilution using femoral indicator injection: a prospective trial in patients with a femoral and a jugular central venous catheter

    PubMed Central

    2010-01-01

    Introduction Advanced hemodynamic monitoring using transpulmonary thermodilution (TPTD) is established for measurement of cardiac index (CI), global end-diastolic volume index (GEDVI) and extra-vascular lung water index (EVLWI). TPTD requires indicator injection via a central venous catheter (usually placed via the jugular or subclavian vein). However, superior vena cava access is often not feasible due to the clinical situation. This study investigates the conformity of TPTD using femoral access. Methods This prospective study involved an 18-month trial at a medical intensive care unit at a university hospital. Twenty-four patients with both a superior and an inferior vena cava catheter at the same time were enrolled in the study. Results TPTD-variables were calculated from TPTD curves after injection of the indicator bolus via jugular access (TPTDjug) and femoral access (TPTDfem). GEDVIfem and GEDVIjug were significantly correlated (rm = 0.88; P < 0.001), but significantly different (1,034 ± 275 vs. 793 ± 180 mL/m2; P < 0.001). Bland-Altman analysis demonstrated a bias of +241 mL/m2 (limits of agreement: -9 and +491 mL/m2). GEDVIfem, CIfem and ideal body weight were independently associated with the bias (GEDVIfem-GEDVIjug). A correction formula of GEDVIjug after femoral TPTD, was calculated. EVLWIfem and EVLWIjug were significantly correlated (rm = 0.93; P < 0.001). Bland-Altman analysis revealed a bias of +0.83 mL/kg (limits of agreement: -2.61 and +4.28 mL/kg). Furthermore, CIfem and CIjug were significantly correlated (rm = 0.95; P < 0.001). Bland-Altman analysis demonstrated a bias of +0.29 L/min/m2 (limits of agreement -0.40 and +0.97 L/min/m2; percentage-error 16%). Conclusions TPTD after femoral injection of the thermo-bolus provides precise data on GEDVI with a high correlation, but a self-evident significant bias related to the augmented TPTD-volume. After correction of GEDVIfem using a correction formula, GEDVIfem shows high predictive capabilities

    Guidelines for the prevention of catheter-related bloodstream infection (CRBSI) recommend subclavian rather than femoral venous access to minimize the risk of CRBSI. However, they do not address the issue of CRBSI with subclavian venous access in the presence of tracheostomy, where the incidence of CRBSI has been found to be higher than without tracheostomy. In this study, we found lower CRBSI in subclavian venous access in the presence of tracheostomy than in femoral venous access (3.9 vs. 10.1 CRBSI per 1000 catheter-days; odds ratio = 0.39; 95% confidence interval ≤0.001-0.91; p 0.03). 2010 The Authors.

    The objective of this study is to determine the catheter-related bloodstream infection (CRBSI) rate in a severely burned patient population, many of whom required prolonged use of central venous catheters (CVCs). Between January 2008 and June 2012, 151 patients underwent placement of 455 five-lumen minocycline/rifampin-impregnated CVCs. CRBSI was defined as at least one blood culture (>100,000 colonies) and one simultaneous roll-plate CVC tip culture (>15 colony forming units) positive for the same organism. Most patients had accidental burns (81.5%) with a mean TBSA of 50%. A mean of three catheters were inserted per patient (range, 1-25). CVCs were inserted in the femoral vein (91.2%), subclavian vein (5.3%), and internal jugular vein (3.3%). Mean overall catheter indwell time was 8 days (range, 0-39 days). The overall rate of CRBSI per 1000 catheter days was 11.2; patients with a TBSA >60% experienced significantly higher rates of CRBSI than patients with a TBSA ≤60% (16.2 vs 7.3, P = .01). CVCs placed through burned skin were four times more likely to be associated with CRBSI than CVCs placed through intact skin. The most common infectious organism was Acinetobacter baumannii. Deep venous thrombosis developed in eleven patients (7%). The overall rate of CRBSI was 11.2, consistent with published rates of CRBSI in burn patients. Thus, femoral placement of 5-lumen CVCs did not result in increased CRBSI rates. These data support the safety of femoral CVC placement in burn patients, contrary to the Centers for Disease Control recommendation to avoid femoral CVC insertion.

To review the use of femoral arterial and venous catheters inserted percutaneously on the neonatal intensive care unit. Infants admitted to one of two regional neonatal intensive care units who underwent femoral vessel catheterisation were identified. Information collected included basic details, indication for insertion of catheter, type of catheter and insertion technique, duration of use, and any catheter related complications. Sixty five femoral catheters were inserted into 53 infants. The median gestational age was 29 weeks (range 23-40). Twenty three femoral arterial catheters (FACs) were inserted into 21 infants and remained in situ for a median of three days (range one to eight). Twelve (52%) FACs remained in place until no longer required, and four (17%) infants developed transient ischaemia of the distal limb. Forty two femoral venous catheters (FVCs) were inserted into 40 infants and remained in situ for a median of seven days (range 1-29). Twenty seven (64%) FVCs remained in place until no longer required, and eight (19%) catheters were removed because of catheter related bloodstream infection. FACs and FVCs are useful routes of vascular access in neonates when other sites are unavailable. Complications from femoral vessel catheterisation include transient lower limb ischaemia with FACs and catheter related bloodstream infection.

    Peripheral arterial catheters are perceived as having low infective potential compared with other catheters and may be overlooked as a cause of catheter-related bloodstream infection. We aimed to measure colonization and rates of catheter-related bloodstream infection in arterial catheters, to investigate risk factors for arterial catheter colonization, and to compare arterial catheter infection rates with those in concurrently sited and managed central venous catheters. Prospective 24-month cohort study. Eight-bed combined general intensive care and high-dependency unit of a 350-bed Australian teaching hospital. Three hundred twenty-one arterial catheters in 252 adult and pediatric patients were observed for 1,082 catheter days, and 618 central venous catheters in 410 patients were observed for 4,040 catheter days. All catheters were inserted in, or presented to, the intensive care unit. Both arterial catheters and central venous catheters were inserted by trained personnel under aseptic conditions, and management was standardized. None. The incidence per 1,000 (95% confidence interval) catheter days of colonization (> or = 15 colonies) and catheter-related bloodstream infection was 15.7 (9.5-25.9) and 0.92 (0.13-6.44) for arterial catheters and 16.8 (13.3-21.3) and 2.23 (1.12-4.44) for central venous catheters. Arterial catheter colonization was not significantly different than that in central venous catheters (hazard ratio, 1.17; 95% confidence interval, 0.41-3.36; p = .77). Arterial catheter colonization increased with dwell time and was similar to central venous catheters over time. Femoral arterial catheters were colonized more often than radial arterial catheters (hazard ratio, 5.08; 95% confidence interval, 0.85, 30.3; p = .075), and colonization was significantly higher when the catheter was inserted in the operating theater or emergency department (hazard ratio, 4.45; 95% confidence interval, 1.42-13.9; p = .01) compared with the intensive care unit.

    Femoral catheters pose a potential barrier to early rehabilitation in the intensive care unit (ICU) due to concerns, such as catheter removal, local trauma, bleeding, and infection. We prospectively evaluated the feasibility and safety of physical therapy (PT) in ICU patients with femoral catheters. We evaluated consecutive medical ICU patients who received PT with a femoral venous, arterial, or hemodialysis catheter(s) in situ. Of 1074 consecutive patients, 239 (22%) received a femoral catheter (81% venous, 29% arterial, 6% hemodialysis; some patients had >1 catheter). Of those, 101 (42%) received PT interventions, while the catheter was in situ, for a total of 253 sessions over 210 medical ICU (MICU) days. On these 210 MICU days, the highest daily activity level achieved was 49 (23%) standing or walking, 57 (27%) sitting, 25 (12%) supine cycle ergometry, and 79 (38%) in-bed exercises. During 253 PT sessions, there were no catheter-related adverse events giving a 0% event rate (95% upper confidence limit of 2.1% for venous catheters). Physical therapy interventions in MICU patients with in situ femoral catheters appear to be feasible and safe. The presence of a femoral catheter should not automatically restrict ICU patients to bed rest. Copyright © 2013 Elsevier Inc. All rights reserved.

    Peripheral nerve catheters are effective and well-established tools to provide postoperative analgesia to patients undergoing orthopedic surgery. The performance of these techniques is usually considered safe. However, placement of nerve catheters may be associated with a considerable number of side effects and major complications have repeatedly been published. In this work, we report on a patient who underwent total knee replacement with spinal anesthesia and preoperative insertion of femoral and sciatic nerve catheters for postoperative analgesia. During insertion of the femoral catheter, significant resistance was encountered upon retracting the catheter. This occurred due to knotting of the catheter. The catheter had to be removed by operative intervention which has to be considered a major complication. The postoperative course was uneventful. The principles for removal of entrapped peripheral catheters are not well established, may differ from those for neuroaxial catheters, and range from cautious manipulation up to surgical intervention.

    A 77-year-old woman was admitted due to AV graft thrombosis; given the technical impossibility of performing other native AV fistulas, we chose to insert a tunnelled central venous catheter. Considering the vascular history of the patient, the central venous catheter could not be placed into the internal jugular vein; it was therefore put into the left femoral vein. Following a 3-month-period of the catheter working properly, the patient was hospitalized due to sudden acute pain in the left thigh. In a few days the patient developed an important haematoma with serious anemization in the left lower limb. Ultrasonography showed the presence of a fistula between the left common femoral artery and the femoral vein, leading to the subsequent successful positioning of a stent into the common femoral artery through right trans-femoral access. Angiography examination showed the femoral vein patency along the proximal stretch with respect to the function of the tunnelled venous catheter.

    2008-03-01

    Central venous catheter fracture is a rare complication of long-term indwelling subclavian venous access. Subclavian vein access has been the recommended approach for placing central venous catheters. The anatomical landmark method for subclavian access remains a highly successful and nonequipment-dependent method for rapid central access. More recently, the internal jugular vein approach has emerged as the preferred route for long-term central venous access. However, variations in internal jugular vein anatomy make the landmark method less reliable. Use of two-dimensional real-time ultrasound during internal jugular vein access is associated with better success, a lower complication rate, and faster access. A case of central venous catheter fracture initiated an internal review of long-term central venous access procedures. We have converted to a predominantly internal jugular vein approach. This case report and literature review may assist other physicians and institutions in re-evaluating long-term central venous access protocols.

    Central venous catheters are of an essential importance to critically ill patients who require long-term venous access for various purposes. Their use made the treatment much easier, but still they are not harmless and are prone to numerous complications. Catheter infections represent the most significant complication in their use. The frequency of infections varies in different patient care settings, but their appearance mostly depends on the patient's health condition, catheter insertion time, localization of the catheter and type of the used catheter. Since they are one of the leading causes of nosocomial infections and related to significant number of morbidity and mortality in intensive care units, it is very important that maximal aseptic precautions are taken during the insertion and the maintenance period. Prevention of infection of the central venous catheters demands several measures that should be applied routinely.

    Background Long-term central venous catheters have improved the quality of care for patients with chronic illnesses, but are complicated by obstructions which can result in delay of treatment or catheter removal. Design and Methods This paper reviews thrombolytic treatment for catheter obstruction. Literature from Medline searches using the terms “central venous catheter”, “central venous access device” OR “central venous line” associated with the terms “obstruction”, “occlusion” OR “thrombolytic” was reviewed. Efficacy of thrombolytic therapy, central venous catheter clearance rates and time to clearance were assessed. Results Alteplase, one of the current therapies, clears 52% of obstructed catheters within 30 min with 86% overall clearance (after 2 doses, when necessary). However, newer medications may have higher efficacy or shorter time to clearance. Reteplase cleared 67–74% within 30–40 min and 95% of catheters overall. Occlusions were resolved in 70 and 83% of patients with one and 2 doses of tenecteplase, respectively. Recombinant urokinase cleared 60% of catheters at 30 min and 73% overall. Alfimeprase demonstrated rapid catheter clearance with resolution in 40% of subjects within 5 min, 60% within 30 min, and 80% within 2 h. Additionally, urokinase prophylaxis decreased the incidence of catheter occlusions from 16–68% in the control group to 4–23% in the treatment group; in some studies, rates of catheter infections were also decreased in the urokinase group. Conclusions Thrombolytic agents successfully clear central venous catheter occlusions in most cases. Newer agents may act more rapidly and effectively than currently utilized therapies, but randomized studies with direct comparisons of these agents are needed to determine optimal management for catheter obstruction.

    The central venous catheter (CVC) is a catheter placed into a large vein in the neck [internal jugular vein (IJV)], chest (subclavian vein or axillary vein) or groin (femoral vein). There are several situations that require the insertion of a CVC mainly to administer medications or fluids, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure. CVC usually remain in place for a longer period of time than other venous access devices. There are situations according to the drug administration or length of stay of the catheter that specific systems are indicated such as; a Hickman line, a peripherally inserted central catheter (PICC) line or a Port-a-Cath may be considered because of their smaller infection risk. Sterile technique is highly important here, as a line may serve as a port of entry for pathogenic organisms, and the line itself may become infected with organisms such as Staphylococcus aureus and coagulase-negative Staphylococci. In the current review we will present the complication of pneumothorax after CVC insertion.

    Multiple benefits of arteriovenous fistulas (AVF) and arteriovenous grafts (AVGs) exist over catheters. As part of a strategy to preserve thoracic venous sites and reduce internal jugular (IJ) vein catheter use, we inserted tunneled femoral vein catheters in incident "urgent start" dialysis patients while facilitating a more appropriate definitive dialysis access. "Urgent start" dialysis patients between January 15, 2013 and January 15, 2014 who required chronic dialysis, and did not have prior modality and vascular access plans, had tunneled femoral vein catheters inserted. We determined the femoral vein catheter associated infections rates, thrombosis, and subsequent dialysis access. Eligible patients were surveyed on their femoral vein catheter experience. Twenty-two femoral vein catheters were inserted without complications. Subsequently, one catheter required intraluminal thrombolytic locking, while all other catheters maintained blood flow greater than 300 ml/min. There were no catheter-related infections (exit site infection or bacteremia). Six patients continued to use their tunneled catheter at report end, one transitioned to peritoneal dialysis, thirteen to an arteriovenous graft, and two to a fistula. One patient received a tunneled IJ vein catheter. Of the patients who completed the vascular access survey, all indicated satisfaction with their access and that they had minimal complaints of bruising, bleeding, or swelling at their access sites. Pain/discomfort at the exit site was the primary complaint, but they did not find it interfered with activities of daily living. Femoral vein tunneled catheters appear to be a safe, well tolerated, and effective temporary access in urgent start dialysis patients while they await more appropriate long-term access.

    Availability of a functional vascular access is a mandatory prerequisite for extracorporeal renal replacement therapy in patients with acute renal failure. The femoral site of insertion commonly is chosen because it is an easy and convenient access. However, an array of complications may substantially alter the quality of treatment, and it appears that catheter-related morbidity and dysfunction are more frequent with the femoral than internal jugular site. This study is designed to evaluate the potential benefits of using soft silicone tunneled catheters ((ST)Caths) at the femoral site. Thirty patients with acute renal failure treated by intermittent hemodialysis (IHD) and/or continuous venovenous hemodiafiltration (CVVHDF) were assigned to either twin (ST)Caths or twin polyurethane nontunneled femoral catheters. Time necessary for catheter insertion, catheter-related complications, and catheter lifespan were monitored. Catheter performance during IHD and the effect of catheter type on dialysis dose were evaluated. The time necessary for (ST)Cath insertion was significantly longer. The incidence of vein thrombosis and catheter-related infection was lower, and the ratio of venous return pressure to catheter blood flow was better with an (ST)Cath. Recirculation rates were similar for both types of catheters. Whether treated by using IHD or CVVHDF, patients with an (ST)Cath benefited from a greater delivered dialysis dose. Multivariate analysis confirmed that (ST)Cath use was a determinant factor to optimize dialysis dose delivery. (ST)Cath patency was significantly longer. In patients with acute renal failure, use of an (ST)Cath minimizes catheter-related morbidity and improves dialysis efficiency compared with conventional femoral catheters.

Position and patency of central venous lines can be incidentally evaluated by using existing central venous catheters for administration of radiopharmaceuticals during radionuclide imaging studies.

    The majority of nosocomial bloodstream infections in critically ill patients originate from an infected central venous catheter (CVC). Catheter-related bloodstream infections (CRBSIs) cause significant morbidity and mortality and increase the cost of care. The most frequent causative organisms for CRBSI are coagulase-negative staphylococci (CoNSs), Staphylococcus aureus, enterococci, and Candida species. The path to infection frequently includes migration of skin organisms at the insertion site into the cutaneous catheter tract, resulting in microbial colonization of the catheter tip and formation of biofilm. Evidence-based strategies for the prevention of CRBSI include behavioral and educational interventions, effective skin antisepsis coupled with maximum barrier precautions, the use of antiseptic dressings, and the use of antiseptic or antibiotic impregnated catheters. Achieving and maintaining very low rates of CRBSI requires a multidisciplinary approach involving the entire health care team, the use of novel technologies in patients with the highest risk of CRBSI, and frequent reeducation of staff.

    Current clinical practice is characterised for importance of the patient's quality of life and the need to reduce the costs of their treatment. We search intravenous therapy alternatives that meet the needs of the patient, reducing the complications associated with the use of venous catheters. Scientific evidence shows that there are midline venous catheters that offer patients and professionals the possibility of extending the duration of infusion therapy, using more venous compatibility materials, and with less risk of infection. The Midlines are becoming in a safe an efficient device for intravenous therapy, continuous and intermittent infusion, provided the necessary care by expert nurses. Midline catheters are peripheral venous access devices between 3 to 10 inches in length (8 to 25 cm). Midlines are usually placed in an upper arm vein, such as the brachial or cephalic, and the distal extreme ends below the level of the axillary line. Midlines catheters implanted in the cephalic or deep basilica veins get more blood flow. This large blood volume justifies the lower risk of mechanical or chemical phlebitis. Midlines are routinely used for two to six weeks. Due that the extrem of these catheters does not extend beyond the axillary line, there are limitations for its use: type of infused drugs, velocity of infusion, etc. In general, solutions that have pH 5 to 9, or an osmolarity less than 500 mOsm are appropriate for infusion through a Midline. Its use is recommended in case of treatments over 7 days with low irritant capacity fluids. According to the Infusion Nurses Society's standards of practice, Midline catheters are appropriate for all intravenous fluids that would normally be administered through a short peripheral IV Importantly, due that the catheter does not pass through the central veins, Midlines can be placed without a chest X-ray to confirm placement. For certain situations, Midlines are suitable for acute units and even for care home settings

    The use of central venous oxygen saturation (SvcO2) and arterial lactate in the diagnosis of severe tissue hypoperfusion is well established, and the optimization of these parameters is currently under investigation, particularly in patients with severe sepsis/septic shock. However, the only place for deep venous puncture or the first choice for puncture is often the femoral vein. Although venous saturation obtained from blood sampling from this catheter, instead of SvcO2, has already been used in the diagnosis of severe tissue hypoperfusion, little is known about the accuracy of the results. The venous lactate in place of arterial puncture has also been used to guide therapeutic decisions. We conducted this literature review to seek evidence on the correlation and concordance of parameters obtained by collecting femoral venous blood gases in relation to SvcO2 and arterial lactate. Few studies in the literature have evaluated the use of femoral venous oxygen saturation (SvfO2) or venous lactate. The results obtained thus far demonstrate no adequate agreement between SvfO2 and SvcO2, which limits the clinical use of SvfO2. However, the apparent strong correlation between arterial and peripheral and central venous lactate values suggests that venous lactate obtained from the femoral vein could eventually be used instead of arterial lactate, although there is insufficient evidence on which to base this procedure at this time.

To collect data in Brazilian and international databases were used the key word bundle and the descriptors catheter-related infection, infection control and central venous catheterization, resulting in fifteen articles, after inclusion criteria application. This work showed five interventions as those commonly employed in the bundles methods: hand hygiene, chlorhexidine gluconate for skin antisepsis, use of maximal sterile barrier precaution during the catheter insertion, avoid the femoral access and daily review of catheter necessity with prompt removal as no longer essential. The majority of the studies showed a significant reduction in bloodstream infection related to or associated with central venous catheters.

    Central venous occlusion in children is a challenging problem that can occur after a central venous catheter insertion. Long-term catheter-related complications include sepsis and venous thrombosis with consequent loss of central access. We describe 2 cases of children younger than 1 year who were dependent on a central venous catheter for total parenteral nutrition. They developed a chronic extensive obstruction of the right and left brachiocephalic veins with a superior vena cava syndrome. The patients' survival was dependent on the restoration of central venous access until the planned intestinal transplantation could be performed. Retrograde recanalization of the superior vena cava was successfully achieved using a pathway created under general anesthesia from the femoral vein to, respectively, the right thyroid vein and the right subclavian vein.

    The guidelines to prevent central venous catheter related bloodstream infections (CVCBSI) of the Centers for Disease Control and Prevention (CDC) of 2002, Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias/ Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEMICYUC/SEIMC) of 2004, and the recently published guidelines of the Society for Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA(IDSA) of 2008 have recommended using the subclavian vein and avoiding the use of the femoral vein. They also recommend considering the use of antiseptic- or antimicrobial-impregnated CVCs for hospital units or groups of patients with a high incidence of CVCBSI. When implementing these guidelines, two questions could be asked: 1) Could the abuse of the subclavian vein and avoiding the use of the femoral vein imply a decrease in the incidence of CVCBSI, but an increase in the rate of mechanical complications as pneumothorax and/or hemothorax? 2) Couldn't antimicrobial-impregnated CVCs be used to prevent CVCBSI when the femoral venous access is used?

    Central venous access is increasingly becoming the domain of the radiologist, both in terms of the insertion of central venous catheters (CVCs) and in the subsequent management of these lines. This article seeks to provide an overview of the CVC types available for paediatric patients and a more detailed explanation of the spectrum of complications that may lead to catheter malfunction. A standard catheter contrast study or ‘linogram’ technique is described. The normal appearances of such a study and a detailed pictorial review of abnormal catheter studies are provided, together with a brief overview of how information from catheter investigations can guide the management of catheter complications.

    The use of central venous catheters (CVCs) in children is escalating, which is likely linked to the increased incidence of pediatric venous thromboembolism (VTE). In order to better understand the specific risk factors associated with CVC-VTE in children, as well as available prevention methods, a literature review was performed. The overall incidence of CVC-VTE was found to range from 0 to 74%, depending on the patient population, CVC type, imaging modality, and study design. Throughout the available literature, there was not a consistent determination regarding whether a particular type of central line (tunneled vs. non-tunneled vs. peripherally inserted vs. implanted), catheter material, insertion technique, or insertion location lead to an increased VTE risk. The patient populations who were found to be most at risk for CVC-VTE were those with cancer, congenital heart disease, gastrointestinal failure, systemic infection, intensive care unit admission, or involved in a trauma. Both mechanical and pharmacological prophylactic techniques have been shown to be successful in preventing VTE in adult patients, but studies in children have yet to be performed or are underpowered. In order to better determine true CVC-VTE risk factors and best preventative techniques, an increase in large, prospective pediatric trials needs to be performed.

    The insertion of central venous catheters is a common bedside procedure performed in intensive care units. Here, we present a case of an 82-year-old man who underwent insertion of a central venous catheter in the internal jugular vein without perceived complications. Postprocedural radiographs showed rostral migration of the catheter, and computed tomography performed coincidentally showed cannulation of the jugular bulb at the level of the jugular foramen. To our knowledge, this is the first report to document migration of a central venous catheter from the internal jugular vein into the dural sinuses, as confirmed by computed tomography. The case highlights the importance of acquiring postprocedural radiographs for all insertions of central venous catheters to confirm catheter placement.

    Two cases of catheter embolization from implanted venous access devices are reported and the available literature is reviewed. The catheter from an implanted venous access device migrated into the right heart after slippage of the O-ring, which attaches the catheter to the infusion port. The distal 6 cm of an infusion port catheter embolized to the right heart after spontaneous fracture of the catheter at the point where it passed between the clavicle and first rib. Both catheters were removed percutaneously without complication. Risk factors for embolization were apparent on x-ray films with evidence of O-ring slippage in 1 case an obvious kinking of the catheter in the other. Symptoms of embolization included chest discomfort, right upper quadrant pain, and nausea. In 1 case, an extra heart sound, initially thought to be an S3, disappeared when the catheter was removed.

    The placement of central venous catheter (CVC) through internal jugular vein is not free from potential hazards. We report two cases of triple lumen central venous catheter, placed into right internal jugular vein, which got entrapped in patients who had undergone mitral valve replacement. The entrapment of catheter went unnoticed until the time of removal. Subsequent investigations, mechanism of entrapment, prevention, and removal is described. To conclude, we encountered an unusual cause of stuck central venous catheter, in the left atrial suture line. Removal of central venous catheter requires utmost care, and should never be done by forceful traction in the postoperative cardiac surgical patients, as it may lead to disruption of suture lines or rupture of vessels.

    The 3SITES study randomly assigned a nontunneled central venous catheter site in over 3000 adults treated in intensive care units. The subclavian site was associated with a lower rate of short-term complications, including catheter-related bloodstream infection and deep venous thrombosis, compared to the femoral or internal jugular site. Nephrologists should be aware of this study and should continue to advocate for alternatives to subclavian vein catheter placement in patients with chronic kidney disease who are expected to require arteriovenous access for dialysis in the future.

    Purpose. The purpose of this study was to evaluate radiological-interventional central venous port catheter corrections in migrated/malpositioned catheter tips. Materials and Methods. Thirty patients with migrated/malpositioned port catheter tips were included in this retrospective analysis. To visualize the catheter patency a contrast-enhanced port catheter series was performed, followed by transfemoral port catheter correction with various 5-F angiographic catheters (pigtail; Sos Omni), gooseneck snares, or combinations thereof. Results. One patient showed spontaneous reposition of the catheter tip. In 27 of 29 patients (93%), radiological-interventional port catheter correction was successful. In two patients port catheter malposition correction was not possible, because of the inability to catch either the catheter tip or the catheter in its course, possibly due to fibrin sheath formation with attachment of the catheter to the vessel wall. No disconnection or port catheter dysfunction was observed after correction. Conclusions. We conclude that in migrated catheter tips radiological-interventional port catheter correction is a minimally invasive alternative to port extraction and reimplantation. In patients with a fibrin sheath and/or thrombosis port catheter correction is often more challenging.

    Infection of perineural catheter is rare, although bacterial colonization is frequent. An observational study reported that subcutaneous tunneling perineural catheter could decrease its colonization rate. We performed a comparative study to assess the incidence of catheter related bacterial colonization of tunnelized femoral perineural catheters. This bicentric, randomized, single-blind, controlled and intention-to-treat study was conducted from December 2009 to December 2011. The catheter was secured with adhesive strips in the control group and was tunneled subcutaneously in the tunnelization group. Primary endpoint was catheter colonization rate assessed by by Brun-Buisson quantitative culture. Secondary endpoints included catheter-related infection, inadvertent catheter dislodgement rate, incidence of technical problems with subcutaneous tunneling and, risk factors for catheter-related colonization. Of the total 338 patients included, 2 patients were later excluded and 78 were lost to follow-up for primary endpoint. Inadvertent removal of femoral catheter accounted for 33 of these 78 patients (10 for the tunnelization group versus 23 for the control group, P=0.02). There was a lower colonization rate in the patient group with tunnelization compared to the control group without tunnelization (6% versus 13.5%, respectively; OR=2.4; 95% CI: 1.1-5.3; P=0.02). No infection was observed. Coagulase-negative staphylococci is present in 61%. The absence of tunnelization is the only risk factor of colonization. For 7 patients, accidental perforation of perineural catheter during procedure was observed. Tunneled subcutaneous perineural catheter decreased the incidence of colonization. Moreover, tunnelization is an effective technique for securing the perineural catheter.

    We analyzed 99 blood cultures taken from 28 children with central venous catheter. Children were hospitalized in pediatric, pediatric surgery and pediatric intensive care department. All samples were collected from peripherial vein. Positive blood cultures were obtained more frequently from children with central venous catheter than from children without central venous catheter (57.5% vs. 7.4%). Staphylococcus epidermidis was the most frequently obtained bacteria. The other bacterial species were obtained less frequently. The highest percentage of multi resistant straines was isolated from blood samples collected from intensive care department patients. In each departments in which coagulase-negative Staphylococci were isolated, metycillin-resistant straines dominated.

    Central venous catheterization is widely used in neonatal intensive care units to support tiny preterm babies. Pericardial effusion (PCE) and cardiac tamponade are uncommon but potentially fatal complications of percutaneous, umbilical and surgically placed central venous catheters related to intracardiac position or migration. This report describes a case of PCE arising from fluid infused via umbilical venous catheter. The case study highlights two important aspects: one, occurrence of PCE in a baby with satisfactory position of the umbilical catheter, and second, the life-saving application of basic echocardiography by bedside caregivers for the diagnosis and treatment of this critical condition.

We report the case of a 31-year-old woman presenting with a malabsorption caused by short gut syndrome due to congenital aganglionic megacolon. The patient developed a chronic occlusion of all central neck and femoral veins due to long-term use of multiple CVCs over more than 20 years. In patients with central venous occlusion and venous transformation, the implantation of a totally implanted port system by accessing collateral veins is an option to continue long-term parenteral nutrition when required. A 0.014-in. Whisper guidewire (Terumo, Tokyo) with high flexibility and steerability was chosen to maneuver and pass through the collateral veins. We suggest this approach to avoid unfavorable translumbar or transhepatic central venous access and to conserve the anatomically limited number of percutaneous access sites.

    To assess the effects of length of continuous femoral catheter on blockade of femoral nerve, lateral femoral cutaneous nerve and obturator nerve. In the study, 70 patients with American Association of Anesthesiologist grades I-II undergoing total knee arthroplasty were randomly divided into three groups, femoral nerve catheters were inserted 5 cm, 10 cm or 20 cm with assistance of a nerve stimulator, patient-controlled analgesia pumps were connected after load of 30 mL 0.3% ropivacaine via the catheters. Sensory blockade of the femoral nerve, lateral femoral cutaneous nerve and obturator nerve were recorded at 24 h postoperatively. Visual analog scale (VAS) pain scores during rest and motion were recorded at 24 h and 48 h postoperatively. The blockade effect of lateral femoral nerve in the 20 cm group was the best. There was no significant difference in sensory blockade between the 5 cm group and the 10 cm group. There was no significant difference in VAS score among the three groups. When continuous femoral nerve block is used for postoperative analgesia after total knee arthroplasty surgery, the catheters that are inserted 5 cm, 10 cm or 20 cm could provide similar and satisfying analgesia effect.

    Venous catheters provide access for hemodialysis (HD) when patients do not have functioning access device. Obstruction of jugular, femoral or even external iliac vessels further depletes options. Subclavian approach is prohibited. Catheterization of inferior vena cava requires specialized equipment and skills. The purpose is to assess a new lifesaving HD vascular access approach for patients with nonfunctioning access device in the ordinary sites. This entails insertion of a retrograde temporary HD catheter in the superficial femoral vein, directing the catheter distally, toward the foot. We included six end-stage renal disease (ESRD) patients retrospectively who are on regular renal replacement therapy and need urgent HD with nonfunctioning access device in the ordinary sites. Successful insertion of six retrograde femoral vein catheters in the superficial femoral vein. The mean catheter days were 2.5±0.5 days with one patient having 26 catheter days. The mean blood pump speed was 230.0±44.7 mL/min. Urea reduction ratio and Kt/V at 3 hours HD session were 47% and 1.5, respectively, which increased with increasing session duration. The ultrafiltration volume was 2-3 L/session which increased up to 6 L/session in case of using slow low-efficiency dialysis. No major complications were observed during insertion or the postinsertion period except thigh pain in one patient and exit site infection in the case of long duration. This is a newly applied lifesaving HD vascular access approach for selected ESRD patients with no available HD vascular access at the ordinary sites with accepted HD adequacy. It needs more evaluation and more studies.

    Central venous catheters (CVCs) in neonates are associated with a risk of central line-associated bloodstream infections (CLABSI). Most reports on the incidence of CLABSI in neonates focus on umbilical venous catheters (UVCs) and peripherally inserted central catheters (PICCs). We evaluated the incidence and risk factors for CLABSI in a cohort of neonates with femoral venous catheters (FVCs), UVCs, and PICCs, with a gestational age ≥34 weeks born between January 1, 2006 and June 30, 2013. We included 2,986 neonates with a total of 656 catheters. The CLABSI incidence rate varied from 12.3 per 1,000 catheter-days in FVCs to 10.6 per 1,000 catheter-days in UVCs and 5.3 per 1,000 catheter-days in PICCs. In a Kaplan–Meier survival analysis, we did not find a difference in CLABSI risk between the catheter types (p = 0.29). The following factors were independently associated with an increased risk of CLABSI: parenteral nutrition [hazard ratio (HR) 2.60, 95% confidence interval (CI) 1.25–5.41], male gender (HR 2.63, 95% CI 1.17–5.90), and higher birth weight (HR 1.04, 95% CI 1.002–1.09), whereas antibiotic treatment at birth (HR 0.25, 95% CI 0.12–0.52) was associated with a decreased risk. Conclusion: In our cohort, we did not find a difference between the CLABSI incidence in FVCs, PICCs, and UVCs. Occurrence of CLABSI is associated with parenteral nutrition, male gender, and higher birth weight. Antibiotic treatment at birth was associated with a decreased risk of CLABSI. PMID:28676849

We studied 147 patients and performed 488 collections after mobilization with either G-CSF alone or chemotherapy + G-CSF, when the white blood cell count exceeded 1 x 10(9)/L, or when a measurable population of CD34+ cells (20/microL) was detected in peripheral blood. All patients received systemic anticoagulation with a low weight heparin and ultrasound examination was performed after the removal of the catheter. Seven patients developed thrombosis (4.7%), ten experienced hematomas at the site of catheter placement (6.8%) despite prophylactic platelet transfusions, while only one patient (0.6%) had a catheter-related infection. In conclusion, the short-term use of large bore femoral catheters in setting up PBSC collection seems to be associated with minimal risk of infection and low thrombotic incidence.

    Cerebral angiography with femoral catheters in two patients was followed by an incomplete cervical transverse myelitis. The complications were thought to be due to high contrast concentration in the cervical spinal vessels because of hypoplasia of one vertebral artery, and to contrast injection into the thyro-cervical trunk.

    Tunnelled femoral catheters with their tip in the lower inferior vena cava (IVC) are proposed only in few cases, but they often provide less than optimal blood flows and frequently have complications. The aim of this prospective observational study is to evaluate the use of 70-cm-long tunnelled cuffed femoral twin Tesio catheters with their tip in the upper IVC for haemodialysis. Between May 2007 and May 2009, 25 tunnelled femoral catheters (fCVC) have been placed in 25 patients (77.7 +/- 10.8 years) with exhausted thoracic venous accesses or old patients with several comorbidities. Two 10 Fr carbothane 70-cm-long Tesio catheters with a Dacron cuff at 45 cm from the tip were placed in the femoral vein of each patient and then tunnelled; tips were in the upper third of the IVC. fCVCs were removed for either malfunction (Qb < 200 ml/min) or infection that did not resolve with antibiotics. Technical success of placement was 100%. The 6- and 12-month assisted primary patency rate were respectively 67 +/- 13% and 54 +/- 17%. The mean session Kt/V was 1.45 +/- 0.19, and the blood flow was 270 +/- 17 ml/min. Six fCVCs have been removed: three for infection, one for accidental damaging and two for the making of a different vascular access. The main complications were 2 catheter tip thrombi, 3 tunnel infections and 11 fCVC-related bacteraemia (1.77 episodes per 1000 CVC-days). The placement of twin fCVCs with their tip in the high IVC can provide an adequate dialysis and can be considered for patients with no remaining thoracic accesses.

    Peripheral vein catheterization is generally considered a harmless procedure. Venous catheter rupture associated with pulmonary embolism is an unlikely but potentially serious complication. We report a case of a peripheral venous catheter (PVC) fracture with pulmonary artery embolization in the left lower lobe treated successfully by a surgical approach. The positioning of a PVC is not always a harmless procedure. Every time there are difficulties in positioning or in removal of a catheter device, it should be carefully inspected to verify integrity. The advisability of removal of these small foreign bodies is debated; percutaneous retrieval is preferred, while surgery should be discussed case by case. PMID:28149586

    Peripherally inserted central catheters (PICC) are widely used to provide central venous access, often in chronically ill patients with long-term intravenous access requirements. There are a number of significant complications related to both insertion and maintenance of PICC lines, including catheter malposition, migration, venous thrombosis, and line fracture. The incidence of these complications is likely to rise as the number of patients undergoing intravenous outpatient therapy increases, with a corresponding rise in radiologist input. This paper provides an overview of the relevant peripheral and central venous anatomy, including anatomical variations, and outlines the complications of PICC lines. Imaging examples demonstrate the range of radiological findings seen in these complications.

    Central venous catheterization (CVC)-related venous thrombosis is a common but serious clinical complication, thus prevention and treatment on this problem should be extensively investigated. In this research, we aimed to investigate the incidence rate of CVC-related venous thrombosis in senile patients and give a further discussion on the related risk factors and predictors. A total of 324 hospitalized senile male patients subjected to CVC were selected. Retrospective investigation and analysis were conducted on age, underlying diseases, clinical medications, catheterization position and side, catheter retention time, and incidence of CVC-related venous thrombosis complications. Basic laboratory test results during catheterization and thrombogenesis were also collected and analyzed. Among the 324 patients, 20 cases (6.17%) of CVC-related venous thrombosis were diagnoseds. The incidence rate of CVC-related venous thrombosis in subclavian vein catheterization was significantly lower than that in femoral vein catheterization (P<0.01) and that in internal jugular vein catheterization (P<0.05). No statistically significant difference was found between femoral vein catheterization and internal jugular vein catheterization (P<0.05). Previous venous thrombosis history (P<0.01), high lactate dehydrogenase level (P<0.01), low high-density lipoprotein (HDL) level (P<0.05), and low albumin level (P<0.05) were found as risk factors or predictors of CVC-related venous thrombosis in senile male patients. Subclavian vein catheterization was the most appropriate choice among senile patients to decrease the incidence of CVC-related venous thrombosis. Previous venous thrombosis history, high lactate dehydrogenase level, low HDL level, and low albumin level were important risk factors in predicting CVC-related venous thrombosis.

    Entrapment of central venous catheters (CVC) at the superior vena cava (SVC) cardiopulmonary bypass cannulation site by closing purse-string sutures is a rare complication of cardiac surgery. Historically, resternotomy has been required for suture release. An endovascular catheter release approach was developed. Four cases of CVC tethering against the SVC wall and associated resistance to removal, suggestive of entrapment, were encountered. In each case, catheter removal was achieved using a reverse catheter fluoroscopically guided over the suture fixation point between catheter and SVC wall, followed by the placement of a guidewire through the catheter. The guidewire was snared and externalized to create a through-and-through access with the apex of the loop around the suture. A snare placed from the femoral venous access provided concurrent downward traction on the distal CVC during suture release maneuvers. In the initial attempt, gentle traction freed the CVC, which fractured and was removed in two sections. In the subsequent three cases, traction alone did not release the CVC. Therefore, a cutting balloon was introduced over the guidewire and inflated. Gentle back-and-forth motion of the cutting balloon atherotomes successfully incised the suture in all three attempts. No significant postprocedural complications were encountered. During all cases, a cardiovascular surgeon was present in the interventional suite and prepared for emergent resternotomy, if necessary. An endovascular algorithm to the "entrapped CVC" is proposed, which likely reduces risks posed by resternotomy to cardiac surgery patients in the post-operative period.

    (1) The signs of infection of implanted port catheters are inflammation along the course of a central catheter, oozing or signs of an abscess of the pocket in which the port is implanted. Catheter-related venous thrombosis should be suspected in the event of pain, oedema, local swelling, a palpable venous cord and development of superficial collateral circulation; (2) The rapid appearance of local signs and symptoms at the time of injection suggests extravasation of the injected drug; (3) Catheter patency should be checked with normal saline, never using too much force if resistance is encountered. If there is a thrombotic occlusion, the catheter can often be unblocked with heparin, or if not, with urokinase. There is only a moderate risk of bleeding if these agents are used carefully.

    We aimed to compare the effectiveness of various catheters for prevention of catheter-related infection and to evaluate whether specific catheters are superior to others for reducing catheter-related infections. We identified randomised, controlled trials that compared different types of central venous catheter (CVC), evaluating catheter-related infections in a systematic search of articles published from January 1996 to November 2009 via Medline, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials. Network meta-analysis with a mixed treatment comparison method using Bayesian Markov Chain Monte Carlo simulation was used to combine direct within-trial, between-treatment comparisons with indirect trial evidence. Forty-eight clinical trials (12 828 CVCs) investigating 10 intervention catheters contributed to the analyses. For prevention of CVC colonisation, adjusted silver iontophoretic catheters (odds ratio: 0.58; 95% confidence interval: 0.33-0.95), chlorhexidine and silver sulfadiazine catheters (0.49; 0.36-0.64), chlorhexidine and silver sulfadiazine blue plus catheters (0.37; 0.17-0.69), minocycline-rifampicin catheters (0.28; 0.17-0.43) and miconazole-rifampicin catheters (0.11; 0.02-0.33) were associated with a significantly lower rate of catheter colonisation compared with standard catheters. For prevention of CRBSI, adjusted heparin-bonded catheters (0.20; 0.06-0.44) and minocycline-rifampicin catheters (0.18; 0.08-0.34) were associated with a significantly lower rate of CRBSI with standard catheters. Rifampicin-based impregnated catheters seem to be better for prevention of catheter-related infection compared with the other catheters.

    Purpose: To determine the patency rates of and factors associated with increased risk of patency failure in patients with femoral vein tunneled hemodialysis catheters. Methods: All femoral tunneled catheter insertions from 1996 to 2006 were reviewed, during which time 123 catheters were inserted. Of these, 66 were exchanges. Patients with femoral catheter failure versus those with femoral catheter patency were compared. Confounding factors, such as demographic and procedural factors, were incorporated and assessed using univariate and multivariable Cox proportional hazards regression analyses. Results: Mean catheter primary patency failure time was 96.3 days (SE 17.9 days). Primary patency at 30, 60, 90, and 180 days was 53.8%, 45.4%, 32.1%, and 27.1% respectively. Crude rates of risk of catheter failure did not suggest a benefit for patients receiving catheters introduced from one side versus the other, but more cephalad location of catheter tip was associated with improved patency. Multivariate analysis showed that patients whose catheters were on the left side (p = 0.009), were of increasing age at the time of insertion (p = 0.002) and that those who had diabetes (p = 0.001) were at significantly greater risk of catheter failure. The catheter infection rate was 1.4/1000 catheter days. Conclusion: Patients who were of a more advanced age and had diabetes were at greater risk of femoral catheter failure, whereas those who received femoral catheters from the right side were less at risk of catheter failure.

    Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible. The subclavian catheter is at a somewhat lower risk of catheter-associated sepsis and symptomatic venous thrombosis than approaches via the internal jugular and femoral veins. Indeed, access via the subclavian vein carries a substantial risk of pneumo- and hemothorax. Damage to the subclavian vein or artery can also occur during deliberate and inadvertent punctures and result in life-threatening complications. Therefore, careful consideration of the access route is required in relation to the patient and the clinical situation, to keep the incidence of complications as low as possible. For catheterization of the subclavian vein, puncture of the axillary vein in the infraclavicular fossa is a good alternative, because ultrasound imaging of the target vessel is easier than in the subclavian vein and the puncture can be performed much further from the lung.

    Central venous catheters (CVC) are frequently used in patients with a hematological disorders in order to administer drugs, stem cell infusions, blood products, parenteral alimentation as well as for blood sampling. There are known mechanical, infectious and thrombotic complications of central venous catheters in hematological patients. Infectious and thrombotic complications have been considered as separate entities so far, but there are theory and accumulating evidence that they are interrelated. Since data on central venous catheters-related thrombosis in hematological patients have been obtained mainly from retrospective studies of small size, prospective randomized studies are warranted. In this review we present current opinions about epidemiology, pathogenesis, diagnosis of CVC-related thrombosis and also its correlations with infectious CVC-related complications.

This article discusses one area, the incidence of central venous catheter-related bloodstream infection in acute care, to examine the available evidence and identify ways in which this evidence can be applied to practice. Research indicates that implementing best practice at the time of insertion is a principal determinant in minimising the risk of catheter-related bloodstream infection.

    Placement of a central venous catheter is one of the most common invasive procedures and is associated with septic and mechanical complications, such as bleeding and pneumothorax. Up to 30% of attempts to cannulate the central vein fail. Correct positioning of the patient can help to maximise the success rate. For placement of catheters in the subclavian vein, patients should be in the Trendelenburg position without the use of a shoulder roll to retract the shoulders. Traditionally, central venous catheters are placed using a 'blind' technique that relies on external anatomical reference marks to localise the vein. However, unnoticed anatomical variations or central venous thrombosis may contribute to cannulation failure with this technique. The use of ultrasound has been shown to increase the success rate and avoid mechanical complications when placing a catheter in the internal jugular vein. It may also increase the success rate in subclavian vein catheterisation. To increase patient safety, the use of ultrasound when placing a central venous catheter should be embraced and become the standard of care.

    Cardiac tamponade secondary to the use of central venous catheter is a rare complication; however, it is potentially reversible when it is caught in time. We report two cases of cardiac tamponade that was diagnosed using a transthoracic echocardiography, followed by urgent pericardiocentesis and surgical pericardial drainage as a complication from umbilical venous catheterization. In one case, the tip of the catheter was properly placed, and in the other case, it was not. In both cases, a hyperosmolar solution was being injected. Although it may be an uncommon situation, it should be always considered as a possibility in a newborn who develops cardiogenic shock without an apparent cause.

    The purpose of this study is to report a novel two-stage Hemodialysis Reliable Outflow (HeRO) graft implantation technique that avoids the use of a femoral bridging hemodialysis catheter in internal jugular vein (IJV) catheter-dependent patients with contralateral central venous occlusion. The first stage is to implant the ePTFE component and consists of: 1) performing two to three incisions in the upper arm ipsilateral to the preexisting IJV catheter, 2) tunneling the expanded polytetrafluoroethylene (ePTFE) component through these incision sites, and 3) placing the ePTFE component in the subcutaneous tissue without anastomosing it to the target artery. The preexisting IJV catheter is maintained to provide continuous dialysis access. The second stage is initiated in 4 weeks and includes: 1) thrombectomy and anastomosing the ePTFE component arterial end to the target artery, 2) insertion of the venous outflow component using the preexisting IJV catheter access site, and 3) connecting the venous outflow component to the ePTFE component in the standard fashion. The HeRO graft was successfully implanted in two stages without using a femoral bridging catheter. Immediate postimplant cannulatabilty was achieved upon completion of the second stage procedure. This novel two-stage HeRO implantation technique is simple, yet allows immediate cannulation upon completion of the second stage procedure while avoiding the need of a femoral bridging catheter in IJV catheter- dependent patients with contralateral central venous occlusion, and thus lowering the risk of infection related to a femoral bridging catheter.

    Central venous catheterization represents a significant medical advancement, particularly in the treatment of critical ill. However, there is a high risk of central venous catheters-related infection. A novel antiseptic central venous catheter, made of polyurethane and impregnated with chlorhexidine and silver sulfadiazine, was developed to reduce the risk of catheters-related infection. In this study, we did a randomized clinical study to determine the efficacy by using antiseptic catheters for the prevention of central venous catheters-related infection in the intensive care units. A total of 204 patients with 235 central venous catheters were studied at the surgical intensive care units at National Taiwan University Hospital between November 1998 and June 1999. Participants received either a standard triple-lumen polyurethane catheter or an antiseptic catheter (Arrow International, Reading, Pennsylvania, USA). Both were indistinguishable from each other. Compared to standard polyurethane catheters, antiseptic catheters were less likely to be colonized by microorganisms when they were cultured at the removal (8.0 versus 20.0 colonized catheters per 100 catheters; relative risk 0.34 [95% CI, 0.15 to 0.74]; p<0.01). There was no significant differences between both groups in catheter-related infections (0.9 versus 4.9 infections per 100 catheters; relative risk 0.17 [95% CI, 0.03 to 1.15]; p = 0.07). Gram-positive cocci and fungi were more likely to colonize in the standard polyurethane catheters (p = 0.06 and 0.04, compared to antiseptic catheters respectively). Two of our cases in the control group died directly due to catheter-related candidemia. No adverse reactions such as hypersensitivity or leukopenia were found in the antiseptic catheter group. Our study showed that central venous catheters with antiseptic coating were safe and had less risk of colonization of bacteria and fungi than standard catheters in the critically ill patients.

    A series of 9 patients of a mean age of 48 years, operated on for compression of the ilio-femoral venous axis is reported. The cause of obstruction was external compression in 3 cases, a retroperitoneal sarcoma in 1 case, and an infrarenal aortic aneurysm in 2. Two patients presented with a Cockett's syndrome, 3 with a chronic ilio-femoral thrombosis, and one with a post-traumatic segmentary stenosis. Treatment consisted in a resection/Dacron grafting of 2 infrarenal aortic aneurysms, one femoro-caval bypass graft, 2 transpositions of the right common iliac artery in the left hypogastric artery for Cockett's syndrome, 3 Palma's operations for chronic thrombosis, and one internal jugular vein interposition for segmentary stenosis. There were no postoperative deaths and no early thromboses of venous reconstructions performed. All the patients were relieved of symptoms during the follow-up period, whose mean length was 38 months. The cause of venous obstruction and the presence of symptoms which are resistant to medical treatment are the main indications to ilio-femoral venous revascularization. The choice of the optimal treatment in each single case yields satisfactory results.

    The purpose of this review is to explore the pathophysiology, epidemiology, and interventional treatment of central vein stenosis (CVS) that may result from central vein catheter (CVC) placement. The precise mechanism of CVC-associated CVS remains largely undefined, though anatomic considerations appear to play a prominent pathologic role. The impact of CVC-associated CVS on arteriovenous fistula outcomes is reviewed. The percutaneous treatment of CVS, observation, angioplasty, or angioplasty with stent placement is reviewed, along with potential surgical treatment options. As the treatment outcomes of CVC-associated CVS have been disappointing, catheter avoidance remains the best strategy.

    One hundred and seven Hickman catheters for haemodialysis were inserted in 90 end-stage chronic renal failure patients, and were used for 1-448 days (median 45 days). Sixty-nine per cent of the patients were treated without any problem for 1-165 days (median 34 days). Clinically evident complications occurred in 44 catheters inserted in 28 patients, and included outflow obstruction (16.8% of the catheters) and thrombosis (13.1% of the catheters). However, many episodes of clotting or insufficient flow could be corrected by simple manoeuvres. Other less frequent complications were recorded: sepsis, mainly in patients with increased risk factors (4.1% of the catheters), laceration of the catheter (3.7%) and occasional cases of jugular-vein phlebitis, transient palsy of a vocal cord, haematoma of the wound, and bleeding of the cutaneous orifice. No clinical sign of subclavian or innominate-vein thrombosis was observed. Nevertheless, a prospective study conducted in 50 asymptomatic patients demonstrated a 12% rate of anomalies of the venous system, although two-thirds of these alterations were mild and had no consequence. When the present series is compared to the results obtained with currently available percutaneous haemodialysis catheters, it is concluded that the Hickman catheter is a safe, comfortable and efficient vascular access device.

    Patients with sickle cell disease (SCD) are prone to develop thrombosis and infection due to their inflammatory and immune deficiency state. These patients require red cell exchange therapy for treatment or prevention of hemoglobin S associated complications. Owing to vascular access problems, adult patients need central venous catheterization (CVC) for exchange procedures. Procedure related complications have been reported for long-term CVCs in pediatric patients. However, short-term CVC complications in adult patients are not clear. This report represents the results of documented complications of short-term CVCs in patients with SCD who undergo apheresis. A total of 142 non-tunneled catheters with average median diameter of 9 F (range 8-16 F) were implanted for apheresis. The catheters were mainly inserted through the right internal jugular vein (66.2 %). Total days of catheter were 412. Results were reported as a complication rate and event according to 1,000 catheter days and compared to a control group including 37 healthy stem cell donors. In the patient group, 1 (1 %) hematoma and 1 (1 %) infection were observed for internal jugular vein catheterization (3.7 hemorrhages and 3.7 infections according to 1,000 catheter days), whereas four (8.9 %) cases of thrombosis and 1 (2.2 %) infection (27 and 6.9 according to 1,000 catheter days) developed in femoral vein. There was a significant difference in terms of thrombosis (P = 0.009). In the control group, only individual developed thrombosis in internal jugular vein. Short-term CVC inserted through to the internal jugular vein seems to be safer than femoral vein in patients with SCD.

    Despite the level of skill of the operator and the use of ultrasound guidance, central venous catheter (CVC) placement can result in CVC malpositioning, an unintended placement of the catheter tip in an inadequate vessel. CVC malpositioning is not a complication of central line insertion; however, undiagnosed CVC malpositioning can be associated with significant morbidity and mortality. The objectives of this review were to describe factors associated with intravascular malpositioning of CVCs inserted via the neck and chest and to offer ways of preventing, identifying, and correcting such malpositioning. A literature search of PubMed, Cochrane Library, and MD Consult was performed in June 2014. By searching for "Central line malposition" and then for "Central venous catheters intravascular malposition," we found 178 articles written in English. Of those, we found that 39 were relevant to our objectives and included them in our review. According to those articles, intravascular CVC malpositioning is associated with the presence of congenital and acquired anatomical variants, catheter insertion in left thoracic venous system, inappropriate bevel orientation upon needle insertion, and patient's body habitus variants. Although plain chest radiography is the standard imaging modality for confirming catheter tip location, signs and symptoms of CVC malpositioning even in presence of normal or inconclusive conventional radiography findings should prompt the use of additional diagnostic methods to confirm or rule out CVC malpositioning. With very few exceptions, the recommendation in cases of intravascular CVC malpositioning is to remove and relocate the catheter. Knowing the mechanisms of CVC malpositioning and how to prevent, identify, and correct CVC malpositioning could decrease harm to patients with this condition.

    Suprapubic catheterization is an alternative method for urinary drainage that is used when transurethral catheterization fails. Traditionally, inserted large-bore suprapubic catheters may cause fatal complications. During the past decade, we used a small central venous catheter (CVC) suprapubicly in 16 male patients for the purpose of urinary drainage, when transurethral catheterization failed. The procedure is performed in no more than 10 minutes. Success rate was 100% and this approach did not lead to any complications. In conclusion, placing a CVC for suprapubic drainage is a safe method with a high success rate and we recommend it in patients with failed transurethral catheterization after a few attempts (2-3 attempts).

    Large numbers of central venous catheters (CVCs) are placed each year and misplacement occurs frequently. This review outlines the normal and abnormal anatomy of the central veins in relation to the placement of CVCs. An understanding of normal and variant anatomy enables identification of congenital and acquired abnormalities. Embryological variations such as a persistent left-sided superior vena cava are often diagnosed incidentally only after placement of a CVC, which is seen to take an abnormal course on X-ray. Acquired abnormalities such as stenosis or thrombosis of the central veins can be problematic and can present as a failure to pass a guidewire or catheter or complications after such attempts. Catheters can also be misplaced outside veins in a patient with otherwise normal anatomy with potentially disastrous consequences. We discuss the possible management options for these patients including the various imaging techniques used to verify correct or incorrect catheter placement and the limitations of each. If the course of a misplaced catheter can be correctly identified as not lying within a vulnerable structure then it can be safely removed. If the misplaced catheter is lying within or traversing large and incompressible arteries or veins, it should not be removed before consideration of what is likely to happen when it is removed. Advice and further imaging should be sought, typically in conjunction with interventional radiology or vascular surgery. With regard to misplaced CVCs, in the short term, a useful aide memoir is: 'if in doubt, don't take it out'.

    The placement of a central venous catheter remains an important intervention in the care of critically ill patients in the emergency department. We propose an ultrasound-first protocol for 3 aspects of central venous catheter placement above the diaphragm: dynamic procedural guidance, evaluation for pneumothorax, and confirmation of the catheter tip location.

    Summary Background Contemporary medical care, especially in the field of pediatrics often requires central venous line (CVC – Central Venous Catheter) implantation for carrying out treatment. Some conditions are treated intravenously for several months, other require long-term venous access due to periodical administration of medications or daily nutritional supplementation. Material/Methods A total number of 309 CVCs were implanted at Children’s University Hospital in Cracow between January 2011 and December 2012 (24 months). Malposition of the CVC is not common. The target of our article was to present two rare cases of malposition of catheters and two displacements of catheter due to chest tumors, and to enhance the importance of differential diagnostic imaging when difficulties occur. Results CVC malposition was detected with different imaging modalities followed by appropriate medical procedures. Conclusions In case of any difficulties with central lines, it is necessary to investigate the underlying cause. The central line team at hospital cooperating with other specialists is needed to detect complications and to prevent them. PMID:25177409

    This report summarizes data obtained via a mailed questionnaire from 129 Department of Veterans Affairs (VA) hospitals regarding current practices in the care of central venous catheters (CVCs) used for total parenteral nutrition (TPN). The size of VA hospitals' acute medical-surgical beds ranged from 14 to 1320 (median 168) beds. Over 6000 patients annually received CVCs for TPN. Hospitals reported using triple-lumen catheters most frequently as their CVC for TPN (80.3%). A povidone-iodine scrub was used to prepare the skin for CVC insertion by 72.6% of reporting hospitals. Sixty percent of hospitals used transparent polyurethane dressings. Care of CVCs varied among hospitals. Catheter-related infection and sepsis rates were within the national average, although < 50% of responding hospitals provided data on these outcomes. The results of this survey point to the need for a national standardized database relative to patients receiving TPN via a CVC.

    Thrombotic occlusion of central venous catheters (CVCs) is a common problem in newborns. There is no guideline that systematically addresses the diagnosis, management, and prevention of this complication. The objective of this review is to establish evidence-based guidance for the management of CVC-related thrombosis. A comprehensive search of the scientific literature was conducted from 1948 to 2012. Twenty-six articles fulfilling four criteria - humans, neonates aged below 28 days, CVC insertion, and English language - were included for analysis. The incidence of thrombosis was 9.2% (308/3332). Singly inserted umbilical venous catheters (UVCs) and peripherally inserted central catheters accounted for over 80% of all CVCs. Frequently reported thrombotic sites were the hepatic vein, right atrium, and inferior vena cava. Symptoms included distal swelling of affected areas and thrombocytopenia. Increased length of catheter stay, infusion of blood products and malpositioned UVCs were identified as risk factors. The commonest diagnostic investigations to confirm thrombosis were echocardiography and ultrasonography. Spontaneous resolution may occur in UVC-related thrombosis, but this warrants close monitoring. Thrombolysis with urokinase alone or combined with low-molecular-weight heparin might be effective and well tolerated as treatment strategies. Prophylactic heparin increases the duration of catheter usability (P < 0.005, 95% confidence interval 0.35-0.81), decreases catheter occlusion, but may not uniformly prevent thrombosis. CVL-related thrombosis is an underreported complication because events in the majority occur silently. Currently, solid evidence-based recommendations for diagnosis and treatment are not possible. Well designed prospective studies are urgently required to establish a concrete investigational approach to CVC-related thrombosis and to institute safe therapeutic modalities.

    Therapeutic and donor apheresis requires adequate vascular access to achieve inlet flow rates of ∼50-100 mL/min. While central dialysis-type venous catheters can usually provide such access, their use includes several associated risks. Some of these risks can be avoided or diminished if adequate peripheral venous access can be established. Some patients have adequate peripheral veins for apheresis that cannot be readily identified visually or by palpation. We hypothesized that ultrasound-guided peripheral venous access would benefit such patients and would lead to placement of fewer central venous catheters. The technique of ultrasound-guided peripheral access for apheresis has been in use at Houston Methodist Hospital since 2012. We performed a prospective review of patients undergoing inpatient and outpatient apheresis at Houston Methodist Hospital from July 1, 2015 to September 30, 2015, to assess its benefit. During this time, we performed 831 procedures on 186 patients, including 787 therapeutic plasma exchanges, three red blood cell exchanges, 41 peripheral stem cell collections. Ultrasound-guided vascular access was used for 68 procedures (8% of all procedures), including 62 therapeutic plasma exchanges, 4 peripheral stem cell collections, and 2 red blood cell changes. Use of ultrasound-guided peripheral access prevented the placement of central venous catheters in 37 (20%) patients, demonstrating its utility in a busy transfusion service. © 2016 Wiley Periodicals, Inc.

  6. Heparin Leakage in Central Venous Catheters by Hemodynamic Transport

    Central venous catheters (CVCs), placed in the superior vena cava for hemodialysis, are routinely filled with heparin, an anticoagulant, while not in use to maintain patency and prevent thrombus formation at the catheter tip. However, the heparin-lock procedure places the patient at risk for systemic bleeding incidences, as heparin is known to leak into the blood stream. We propose that the driving mechanism behind heparin leakage is advective-diffusive transport due to the pulsatile blood flow surrounding the catheter tip. This novel hypothesis is based on Planar Laser Induced Fluorescence (PLIF) measurements of heparin transport from a CVC placed inside an in vitro pulsatile flow loop and validated with CFD simulations. The results show an initial, fast (<10s), advection-dominated phase that rapidly depletes the concentration of heparin at the CVC tip, followed by a slow, diffusion-limited phase inside the catheter lumen, where concentration is still high, that is insufficient at replenishing the lost heparin at the tip. These results, which estimate leakage rates consistent with published in vivo data, predict that the concentration of heparin at the catheter tip is effectively zero for the majority of the interdialytic phase, rendering the heparin lock ineffective.

    Antibiotic lock therapy (ALT) is an adjunctive procedure to prevent or treat central venous catheter infections, ensuing catheter-related bacteremia, and catheter-related metastatic infections. Daptomycin is a cyclic lipopeptide that is rapidly bactericidal against methicillin-susceptible and -resistant Staphylococcus aureus. The efficacies of daptomycin against central venous catheter biofilms, catheter-related bacteremia, and catheter-related metastatic infections were evaluated by adapting a previously reported central venous catheter biofilm model in rats. Combined daptomycin ALT and systemic dosing resulted in the clearance of an established in vivo S. aureus central venous catheter biofilm after just two daily ALT treatments (30 min with daptomycin at 5 mg/ml) with concurrent systemic daptomycin dosing (40 mg/kg of body weight/day subcutaneously [s.c.]; equivalent exposure of 6 mg/kg/day in people). Daptomycin ALT solutions formulated in either saline or lactated Ringer's solution were equally fast in eradicating established in vivo methicillin-resistant Staphylococcus epidermidis (MRSE) central venous catheter biofilms. However, the lactated Ringer's formulation was superior to that of saline in sustaining the bacterial clearance of treated central venous catheters (83% versus 50%). In MRSE-infected central venous catheter studies, 3 days of daptomycin or vancomycin ALT (18 h at 5 mg/ml) with systemic s.c. dosing (40 mg/kg/day daptomycin or 100 mg/kg/day vancomycin) was equally effective 1 week posttherapy in maintaining cleared central venous catheters (90% [n = 10] versus 100% [n = 8]). These results suggest that daptomycin ALT, along with systemic dosing, could be an effective treatment option for the prevention or eradication of staphylococcal central venous catheter biofilm infections, thereby reducing the occurrence of catheter-related bacteremia or catheter-related metastatic infections.

    Central venous catheters are used for delivering medications and parenteral nutrition, measuring hemodynamic variations, and providing long-term intravenous access. In our clinic, during liver transection using a living-liver donor, peripherally inserted central venous catheters are generally preferred because they involve a less invasive technique with a lower risk of complications. In this report, we present the case of a 36-year-old male liver donor into whom we peripherally inserted a central venous catheter from his left basilic vein. After transecting the hepatic vein, the surgeon found foreign material inside the venous lumen, which turned out to be the distal segment of the catheter.

    Thirty-one patients with suspected central venous catheter-related bacteremia were evaluated with comparative quantitative cultures of central venous and peripheral blood specimens. Using criteria developed from studies in bacteremic animals, 19 patients were confirmed to have catheter-related bacteremia. Antibiotic therapy was administered through the catheter (in situ therapy) in 17 of those patients to evaluate the feasibility of treating patients with true central venous catheter-related bacteremias without catheter removal. Bacteremia was successfully eradicated in 11 of 17 patients (65%), allowing 7 patients to retain their catheter a median of 157 days. This study validates the use of comparative quantitative blood cultures in the diagnosis of catheter-related bacteremia and indicates that in situ therapy is a rational alternative to catheter removal in patients with catheter-related bacteremia.

    Intravascular device placement (IVD) is a part of everyday medical practice, however, its application is associated with a high risk of onset of nosocomial infections (NI) and increased mortality and morbidity. Nosocomial blood infections (NBIs) account for 10% of all the registered NI. NBIs are more frequent in patients with a placed IVD and it present an important risk factor for the onset of NBI, i.e. catheter-associated NBIs (CANBIs). Pathogenesis of CANBIs is complex and conditioned by the presence of different characteristics related to a catheter, patient and a specific causative organism. The most common CRBSI causes include coagulase-negative staphylococcus, S. aureus, Enterobacter spp, Candida spp, Klebsiella spp, Pseudomonas spp. and Enterococcus spp. All the patients hospitalized at the Intensive Care Department of the Clinic of Digestive Diseases over the period January 1, 2004-September 1, 2004 were retrospectively analyzed. The study included 107 patients in whom central venous catheter (CVC) was placed for more than 48 h. All the causes isolated from a CVC segment were recorded. Culture, isolation and identification of the causative organisms were performed using standard microbiological methods in the Bacteriological Laboratory within the Emergency Center, Clinical Center of Serbia. Catheter segment samples (tip of the CVC 3-5 cm long) were analyzed. Based on the insight into medical documentation, patients' examination and medical staff interview, catheter and patient-related characteristics were recorded. A total of 107 CVCs were analyzed, out of which 56 (52%) were sterile while 51 (48%) were colonized. The results of our study evidenced that total parenteral nutrition (TPN) (p < 0.05), number of catheterization days (p < 0.05), and central venous pressure measurement (p < 0.05) were significantly associated with CVC colonization. In this study, no statistically significant difference in catheter colonization was found with respect to sex, age

    The results of fibrinolytic therapy with urokinase were evaluated in 26 neonates with catheter related central venous thrombosis. Complete thrombolysis could be achieved in 13 patients (50%), partial thrombolysis in 3 patients (12%). No effect was seen in 10 patients (38%). Therapy success was influenced by age, size and location of the thrombus. Coincidence of infection occurred in 16 patients (62%). Mild hemorrhagic complications were seen in 2 patients (8%), no other significant side effects were observed. Nine patients with residual thrombosis were treated with oral anticoagulants following urokinase resulting in resolution of the thrombus in 6 patients within 3 months (67%). The incidence of asymptomatic recurrent thrombosis was high (28%). Urokinase might be an effective and safe treatment for central venous thrombosis in neonates. Prophylactic antibiotic therapy during the infusion of urokinase and long-term treatment with oral anticoagulants after thrombosis are advisable. Early detection of thrombosis might enhance the success rate of fibrinolytic therapy. Therefore, we strongly recommend routine echocardiographic screening of central venous catheters.

    We compared catheter survival and sepsis rates in a tertiary paediatric gastroenterology centre with those at home in the same patients. We examined whether there were differences in the safety in the two locations, and estimated the financial and opportunity cost implications of any difference. We used survival analysis to analyse differences. Surgical records were audited to determine venous access workload, and to estimate cost implications. Twenty patients with chronic intestinal failure but stable parenteral nutrition requirements, ranging from 0.04-15.83 years of age were studied. The duration of line survival and sepsis-free intervals and rates of re-operation for venous access were determined to estimate morbidity and costs. The study encompassed 28 patient-years in hospital and 48 patient-years at home. There was a significant reduction in the rate of sepsis at home compared with hospital (Z = 4.30, P < 0.00001), and a similar improvement in line survival (Z = 4.36, P < 0.00001). Line insertions accounted for 21% of minor surgery in our hospital, one third being reinsertions. We conclude that central venous catheter sepsis rates are greatly improved at home. If home results could be achieved in the hospital setting, considerable cost savings would be made.

    Long-term or repeated venous access in chelonians is difficult to obtain and manage, but can be critically important for administration of medications and blood sampling in hospitalized patients. Jugular catheterization provides the most rapid and secure route for vascular access, but catheters can be difficult to place, and maintaining catheter patency may be challenging. Long multilumen polyurethane catheters provide flexibility and sampling access, and minimize difficulties, such as catheter displacement, that have been encountered with traditional over-the-needle catheters. We describe placement of 4 Fr. 13-cm polyurethane catheters in three chelonians with the use of a modified Seldinger technique. Venous access was obtained with the use of an over-the-needle catheter, which allowed placement of a 0.018-in.-diameter wire, over which the polyurethane catheter was placed. Indwelling time has ranged between 1 and 4 mo currently. All tortoises were sedated for this procedure. Polyurethane central catheters provide safe, long-term venous access that allows clinicians to perform serial blood sampling as well as intravenous administration of medications, anesthetic agents, and fluids. A jugular catheter can also allow central venous pressure measurement. Utilization of central line catheters was associated with improvements in diagnostic efficiency and therapeutic case management, with minimal risks and complications.

    Aim Central venous access is frequently provided by way of umbilical venous catheter placement in critically ill newborns. This study compared the methods of Dunn, Shukla-Ferrara, and Revised Shukla-Ferrara in determining the appropriate insertion length of umbilical vein catheters. Material and Methods This prospective observational study was carried out in 121 newborns with umbilical venous catheter, group 1 (n=41) used Dunn method, group 2 (n=40) used the Shukla-Ferrara formula, and group 3 used revised Shukla-Ferrara formula (n=40). Catheter tip position was evaluated with an anterior-posterior chest radiograph after insertion of the umbilical venous catheter. The ideal position for the umbilical venous catheter was defined as the catheter tip being visible between the 9th and 10th thoracic vertebrae on an anterior-posterior chest radiograph. The position of the umbilical venous catheter was considered too high if the tip of the catheter was higher than the 9th thoracic vertebra and too low if the tip was below the 10th thoracic vertebra. The following data were collected: appropriate, inappropriate (low, high) placement, and complications of umbilical venous catheterization. Results In the Shukla-Ferrara group, 53% (17/32) of umbilical venous catheters were placed directly in the appropriate position, compared with 40% (12/30) in the revised Shukla-Ferrara group and 38% (11/29) in the Dunn method group. Umbilical venous catheter-related complications developed in two patients, thrombus in one, and catheter-related blood stream infection in the other. Conclusions This study showed that the Shukla-Ferrara formula is more accurate in predicting the insertion length for umbilical venous catheters, though statistical significance was not found. Further studies with larger samples are needed on this topic. PMID:28439199

    The use of central venous catheters (CVCs) represents an important step in the management of the surgical, onco-hematology and critically ill patients. CVCs in neonates, like in adult patients, are mainly used to infuse hyperosmolar solutions, to take blood samples and for hemodynamic monitoring. The need for CVCs is higher in neonates than in adults. Poor peripheral access and the high demand for IV access and blood samples are already valuable indications for a CVC.

    To investigate the relationship between central venous oxygen saturation (ScvO(2)) and femoral venous oxygen saturation (SfvO(2)) in a large group of critically ill patients. Observational study. A group of unselected critically ill patients with central line placed into superior vena cava were included. A 26-bed intensive care unit in a tertiary referral hospital. None. Venous blood samples of superior vena cava and femoral vein were collected within an interval of 5 to 15 minutes and analyzed with blood gas/electrolyte analyzer immediately. Although SfvO(2) was significantly correlated with ScvO(2) (r = 0.493, P < .001; Pearson correlation, 2 tailed), the limits of agreement were wide (up to 61% to -41%) between the 731 pairs of blood samples collected from 357 patients. The fit line of scatter diagram ScvO(2) vs SfvO(2) had a large intercept (48.68%) and a low slope (0.2978); ScvO(2) was still around 50% while SfvO(2) was nearing 0%. The distribution of blood flow, measured with Doppler ultrasound, had a similar trend in 237 patients and 412 measurements. The ratio of femoral artery flow over common carotid artery flow varied widely (from 0 to 7.13). Blood flow was not distributed in a fixed ratio to the superior vena cava-drained organs and tissues. Central venous oxygen saturation was not representative of the whole systemic circulation in critically ill patients. Central venous oxygen saturation alone might be misleading in goal-directed therapy. Copyright © 2015 Elsevier Inc. All rights reserved.

  19. Prevention of central venous catheter-related infection: update.

    Casey, Anna L; Elliott, Tom S J

    Central venous catheters (CVCs) are an essential part of modern-day healthcare, but infections associated with these devices continue to cause significant morbidity and mortality. There are many approaches for the prevention of CVC-related infection and these are outlined in national guidelines. The Department of Health Saving Lives campaign has developed a care-bundle for the prevention of CVC-related infections that focuses on the fundamental actions to be undertaken during the catheter insertion process and ongoing care. If the rate of catheter-related infection remains high despite the implementation of these infection prevention strategies, the use of novel antimicrobial technologies and practices may be considered. These include CVCs that contain antimicrobial agents, such as antiseptics or antibiotics, needleless intravenous (IV) access devices coated with silver and/or chlorhexidine, IV dressings incorporating chlorhexidine, and the use of antimicrobial catheter lock solutions, such as antibiotics, chelators or ethanol. This article outlines the different types of CVCs available, the risk of infection associated with their use and established and novel measures for prevention of these infections.

    Central venous catheters (CVC) are used to provide vascular access during hemodialysis in patients with end-stage kidney disease. Despite several advantages and widespread use, CVCs have a high incidence rate of clot formation during the interdialytic phase (48 hrs). In an attempt the prevent clot formation, hospitals routinely administer heparin, an anticoagulant, into the catheter after a dialysis session. It has been reported, however, that up to 40% of the heparin solution will leak into the blood stream during the interdialytic phase, placing the patient at risk for systemic bleeding incidences. The aim of this study is to determine the role that advective-diffusive transport plays in the heparin leaking process. Numerical simulations of heparin convective mass transfer have been conducted, showing that while advective losses may be significant at the tip, previous studies may be overestimating the total amount of heparin leakage. To validate the quantitative prediction from the simulations, P.L.I.F. is used to experimentally measure heparin transport from CVCs placed in an idealized Superior Vena Cava with physically accurate pulsatile flow conditions. Improved understanding of flow near the catheter tip is applied to improve catheter design and heparin locking procedures.

    Suprapubic catheterization is an alternative method for urinary drainage that is used when transurethral catheterization fails. Traditionally, inserted large-bore suprapubic catheters may cause fatal complications. During the past decade, we used a small central venous catheter (CVC) suprapubicly in 16 male patients for the purpose of urinary drainage, when transurethral catheterization failed. The procedure is performed in no more than 10 minutes. Success rate was 100% and this approach did not lead to any complications. In conclusion, placing a CVC for suprapubic drainage is a safe method with a high success rate and we recommend it in patients with failed transurethral catheterization after a few attempts (2–3 attempts).

    The Peripherally Inserted Central Catheter (PICC) has been used as a safe venous access for infants at risk. The aim of this study was to describe the knowledge and practice of nurses from the five public Neonatal Intensive Care Units, of Recife-PE, Brazil, about the use of the PICC. The sample was comprised by 52 nurses; data were collected from January to February/2010. It was found that 64,8% of nurses did not have license for insertion of the PICC. Only two units routinely used the PICC. About the indication of the access, the accuracy was above 70%. In unit B only 8,3% of nurses reported adequate initial location of the catheter tip. It was concluded that is necessary greater incentives to train nurses to use the PICC.

    A central venous catheter enables the measurement of hemodynamic variations, such as accurate central venous pressure; catheter malposition may induce potentially fatal complications. This case report describes a rare central venous catheter tip malposition in the right internal mammary artery. A 56-year-old Japanese woman who presented with severe pneumonia secondary to scleroderma was treated under ventilator support because of acute respiratory failure. A right central venous catheter was inserted using a landmark technique to monitor central venous pressure and administer medications. However, central venous waveforms detected by the catheter using a pressure lot transducer were later found to be absent. Further imaging studies, including plain radiography, computed tomography, and angiography, confirmed central venous catheter malposition in the internal mammary artery. Her right internal mammary artery was embolized using two interlocking detachable coils, and the central venous catheter was removed from her internal mammary artery without further complications. Internal mammary artery malposition is a rare but potentially lethal complication of central venous catheter catheterization; however, caution should be taken regarding the assessment of risk factors and management of a severe complication. An ultrasound-guided approach would be helpful.

    Femoral venous catheterization is a common, invasive procedure, which may lead to serious complications. Validated checklists are central to teaching and assessing procedural skills and may result in improved health care quality. The results of the first step of the validation of a femoral venous catheterization checklist are described. A comprehensive literature review of articles published on femoral venous catheterization did not yield a checklist validated by the Delphi method. A modified Delphi technique, involving a panel of 8 interdisciplinary, interinstitutional experts, was used to develop a femoral venous catheterization checklist. The internal consistency coefficient using Cronbach α was .99. Developing a 29-item checklist for teaching and assessing femoral venous catheterization is the first step in the validation process. For this checklist to become further validated, it should be implemented and studied in the simulation and clinical environments.

    To evaluate the risk factors associated with an increased risk of symptomatic peripherally inserted central venous catheter (PICC)-related venous thrombosis. Retrospective analyses identified 2313 patients who received PICCs from 1 January 2012 to 31 December 2013. All 11 patients with symptomatic PICC-related venous thrombosis (thrombosis group) and 148 who did not have thromboses (non-thrombosis group) were selected randomly. The medical information of 159 patients (age, body mass index (BMI), diagnosis, smoking history, nutritional risk score, platelet count, leucocyte count as well as levels of D-dimer, fibrinogen, and degradation products of fibrin) were collected. Logistic regression analysis was undertaken to determine the risk factors for thrombosis. Of 2313 patients, 11 (0.47%) were found to have symptomatic PICC-related venous thrombosis by color Doppler ultrasound. Being bedridden for a long time (odds ratio [(OR]), 17.774; P=0.0017), D-dimer >5 mg/L (36.651; 0.0025) and suffering from one comorbidity (8.39; 0.0265) or more comorbidities (13.705; 0.0083) were the major risk factors for PICC-catheter related venous thrombosis by stepwise logistic regression analysis. Among 159 patients, the prevalence of PICC-associated venous thrombosis in those with ≥1 risk factor was 10.34% (12/116), in those with ≥2 risk factors was 20.41% (10/49), and in those with >3 risk factors was 26.67% (4/15). Being bedridden >72 h, having increased levels of D-dimer (>5 mg/L) and suffering from comorbidities were independent risk factors of PICC-related venous thrombosis.

  6. Adjacent central venous catheters can result in immediate aspiration of infused drugs during renal replacement therapy.

    2012-02-01

    Dual-lumen haemodiafiltration catheters enable continuous renal replacement therapy in the critically ill and are often co-located with central venous catheters used to infuse drugs. The extent to which infusions are immediately aspirated by an adjacent haemodiafiltration catheter remains unknown. A bench model was constructed to evaluate this effect. A central venous catheter and a haemodiafiltration catheter were inserted into a simulated central vein and flow generated using centrifugal pumps within the simulated vein and haemodiafiltration circuit. Ink was used as a visual tracer and creatinine solution as a quantifiable tracer. Tracers were completely aspirated by the haemodiafiltration catheter unless the infusion was at least 1 cm downstream to the arterial port. No tracer was aspirated from catheters infusing at least 2 cm downstream. Orientation of side ports did not affect tracer elimination. Co-location of central venous and haemodiafiltration catheters may lead to complete aspiration of infusions into the haemodiafilter with resultant drug under-dosing.

  7. Cost-Effectiveness of a Central Venous Catheter Care Bundle

    2010-01-01

    Background A bundled approach to central venous catheter care is currently being promoted as an effective way of preventing catheter-related bloodstream infection (CR-BSI). Consumables used in the bundled approach are relatively inexpensive which may lead to the conclusion that the bundle is cost-effective. However, this fails to consider the nontrivial costs of the monitoring and education activities required to implement the bundle, or that alternative strategies are available to prevent CR-BSI. We evaluated the cost-effectiveness of a bundle to prevent CR-BSI in Australian intensive care patients. Methods and Findings A Markov decision model was used to evaluate the cost-effectiveness of the bundle relative to remaining with current practice (a non-bundled approach to catheter care and uncoated catheters), or use of antimicrobial catheters. We assumed the bundle reduced relative risk of CR-BSI to 0.34. Given uncertainty about the cost of the bundle, threshold analyses were used to determine the maximum cost at which the bundle remained cost-effective relative to the other approaches to infection control. Sensitivity analyses explored how this threshold alters under different assumptions about the economic value placed on bed-days and health benefits gained by preventing infection. If clinicians are prepared to use antimicrobial catheters, the bundle is cost-effective if national 18-month implementation costs are below $1.1 million. If antimicrobial catheters are not an option the bundle must cost less than $4.3 million. If decision makers are only interested in obtaining cash-savings for the unit, and place no economic value on either the bed-days or the health benefits gained through preventing infection, these cost thresholds are reduced by two-thirds. Conclusions A catheter care bundle has the potential to be cost-effective in the Australian intensive care setting. Rather than anticipating cash-savings from this intervention, decision makers must be prepared

    There are few reported cases of death attributed to retrograde cerebral air embolism from central venous catheter. The pathophysiological mechanism and the necessary conditions are not fully understood, also because of missing experimental data. We performed experimental simulation while working on a possible case of retrograde cerebral air embolism. A hermetic system consisting of two containers connected to each other and to an electric pump by means of rubber hoses was built. In this system, a fluid (water and blood) could continuously flow under conditions similar to those of the common jugular vein. The part of the system representing the jugular vein could be freely positioned at angles between 0 and 90°. A central venous catheter was inserted into this part. After disconnection, the behavior of the air bubbles entering the hose through the tip of the catheter was evaluated at different positions. At angles between 0 and 45°, the air bubbles followed the fluid flow. At angles >45°, the air bubbles showed the tendency to flow upstream; this phenomenon was more evident the more vertically the hose was located. We were able to demonstrate that a retrograde air embolism can be caused by a disconnected catheter and is even more likely if the neck is in a vertical position. © 2010 American Academy of Forensic Sciences.

    This experiment was conducted to evaluate efficacy and safety of the Oasis thrombectomy catheter on arterial thrombosis in dogs. Thrombosis was induced in 18 femoral arteries of nine mongrel dogs. Recanalization of the thrombosed femoral artery was performed using a thrombectomy catheter 7-10 days after thrombus induction. Pre- and postprocedural arterial status was documented by angiography. After mechanical thrombectomy, the animals were sacrificed and the femoral arteries were harvested and examined macro- and microscopically. Additionally, in vitro fragmentation was carried out to determine particle size and distribution from the recovered effluent. Subacute thrombosis was successfully created in 15 femoral arteries. Full recanalization was achieved in 80% (12/15) of the thrombosed femoral arteries without any residual thrombus. No significant downstream embolization was documented angiographically. Endothelial denudation was observed in all the treated arteries along with occasional disruption of the internal elastic lamina. No medial injury was seen. Ninety-eight percent of thrombus was liquefied, defined as particles smaller than 15 microm, by the catheter. Particles larger than 400 microm represented 0.27% of the original clot weight. Occluded femoral arteries with 7- to 10-day-old thrombus can be efficiently recanalized with the Oasis catheter in dogs without any significant complication. This thrombectomy catheter appears to be highly effective and safe and requires no sophisticated equipment. Blood loss was our major concern regarding use of this catheter but can be minimized by strictly controlling activation time and restricting the inflow into the vascular segment being treated.

    Perforation by central venous catheters into the extravascular space is a rare complication of central venous lines that may explain new onset shortness of breath in hospitalized patients. We found that lowering bottles containing infusate and looking for return of venous blood is a highly specific test for this problem. Using Bayes' Theorem we calculated that for prior probabilities of catheter perforation of 0.01 and 0.05, corresponding posterior probabilities ranged from 0.1 to 0.15 and 0.35 to 0.49 respectively. This test should be used in all patients with new shortness of breath who have central venous catheters.

    Although real-time ultrasound guidance during central venous catheter insertion has become a standard of care, postinsertion chest radiograph remains the gold standard to confirm central venous catheter tip position and rule out associated lung complications like pneumothorax. We hypothesize that a combination of transthoracic echocardiography and lung ultrasound is noninferior to chest radiograph when used to accurately assess central venous catheter positioning and screen for pneumothorax. All operating rooms and surgical and trauma ICUs at the institution. Single-center, prospective noninferiority study. Patients receiving ultrasound-guided subclavian or internal jugular central venous catheters. During ultrasound-guided central venous catheter placement, correct positioning of central venous catheter was accomplished by real-time visualization of the guide wire and positive right atrial swirl sign using the subcostal four-chamber view. After insertion, pneumothorax was ruled out by the presence of lung sliding and seashore sign on M-mode. Data analysis was done for 137 patients. Chest radiograph ruled out pneumothorax in 137 of 137 patients (100%). Lung ultrasound was performed in 123 of 137 patients and successfully screened for pneumothorax in 123 of 123 (100%). Chest radiograph approximated accurate catheter tip position in 136 of 137 patients (99.3%). Adequate subcostal four-chamber views could not be obtained in 13 patients. Accurate positioning of central venous catheter with ultrasound was then confirmed in 121 of 124 patients (97.6%) as described previously. Transthoracic echocardiography and lung ultrasound are noninferior to chest x-ray for screening of pneumothorax and accurate central venous catheter positioning. Thus, the point of care use of ultrasound can reduce central venous catheter insertion to use time, exposure to radiation, and improve patient safety.

    Central venous catheters are used in various hospital wards. An anterior-posterior chest X-ray is usually obtained soon after cannulation to assess the location of the catheter tip. This prospective clinical study was designed to determine the radiographic catheter tip position after central venous cannulation by various routes, to identify clinical problems possibly associated with the use of malpositioned catheters and to make a cost-benefit analysis of routine chest X-ray with respect to catheter malposition. A total 1619 central venous cannulations were recorded during a three-year period with respect to patient data, information about the cannulation procedures, the radiographic catheter positions and complications during clinical use. The total incidence of radiographic catheter tip malposition, defined as extrathoracic or ventricular positioning, was 3.3% (confidence interval 25 to 4.3%). Cannulation by the right subclavian vein was associated with the highest risk of malposition, 9.1%, compared with 1.4% by the right internal jugular vein. Six of the 53 malpositioned catheters were removed or adjusted. No case of malposition was associated with vascular perforation, local venous thrombosis or cerebral symptoms. We conclude that the radiographic incidence of central venous catheter malpositioning is low and that clinical use of malpositioned catheters is associated with few complications. However, determination of the catheter position by chest X-ray should be considered when mechanical complications cannot be excluded, aspiration of venous blood is not possible, or the catheter is intended for central venous pressure monitoring, high flow use or infusion of local irritant drugs.

    The central venous catheter (CVC) is a device used for many functions, including monitoring haemodynamic indicators and administering intravenous medications, fluids, blood products and parenteral nutrition. However, as a foreign object, it is susceptible to colonisation by micro-organisms, which may lead to catheter-related blood stream infection (BSI) and in turn, increased mortality, morbidities and health care costs. To assess the effects of skin antisepsis as part of CVC care for reducing catheter-related BSIs, catheter colonisation, and patient mortality and morbidities. In May 2016 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations and Epub Ahead of Print); Ovid EMBASE and EBSCO CINAHL Plus. We also searched clinical trial registries for ongoing and unpublished studies. There were no restrictions with respect to language, date of publication or study setting. We included randomised controlled trials (RCTs) that assessed any type of skin antiseptic agent used either alone or in combination, compared with one or more other skin antiseptic agent(s), placebo or no skin antisepsis in patients with a CVC in place. Two authors independently assessed the studies for their eligibility, extracted data and assessed risk of bias. We expressed our results in terms of risk ratio (RR), absolute risk reduction (ARR) and number need to treat for an additional beneficial outcome (NNTB) for dichotomous data, and mean difference (MD) for continuous data, with 95% confidence intervals (CIs). Thirteen studies were eligible for inclusion, but only 12 studies contributed data, with a total of 3446 CVCs assessed. The total number of participants enrolled was unclear as some studies did not provide such information. The participants were mainly adults admitted to intensive care units, haematology oncology units or general wards

Clinically significant infection due to Bacillus species is rare and mostly due to Bacillus cereus infections in immuno-compromised hosts. Case presentation We report a case of central venous catheter infection with Bacillus pumilus in an immunocompetent child with tufting enteropathy on long-term parenteral nutrition (PN). There were three episodes of central venous catheter infection with Bacillus pumilus in three months. Despite adequate and appropriate use of intravenous antibiotics, the infection failed to clear resulting in the need for removal of the catheter for complete cure. Conclusion Bacillus species can cause clinically significant central venous catheter infection, even in an immunocompetent host. Despite adequate antibiotic treatment, the central venous catheter may need removal for complete cure. PMID:17967173

    Antimicrobial-impregnated catheters are more expensive than standard catheters (S-C). A higher incidence of catheter-related bloodstream infection (CRBSI) has been found in jugular venous access with tracheostomy than without tracheostomy. The objective of this study was to determine central venous catheter (CVC)-related costs (considering only the cost of the CVC, diagnosis of CRBSI, and antimicrobial agents used to treat CRBSI) using rifampicin-miconazole-impregnated catheters (RM-C) or S-C in jugular venous access with tracheostomy. We performed a retrospective cohort study of patients admitted to the intensive care unit (ICU) with tracheostomy who received one or more jugular venous catheters. RM-C showed a lower incidence of CRBSI compared with S-C (0 vs. 20.16 CRBSI episodes/1,000 catheter-days; odds ratio=0.05; 95% confidence interval=0.001-0.32; p<0.001) and lower CVC-related costs (including the cost of the CVC, diagnosis, and treatment of CRBSI) (11.46 ± 6.25 vs. 38.11 ± 77.25; p<0.001) in jugular venous access with tracheostomy. The use of RM-C could reduce CVC-related costs in jugular venous access with tracheostomy. The results of our study may contribute to clinical decision-making and selection of those patients who could benefit from the use of antimicrobial-impregnated catheters.

    Patients with central venous catheters (CVCs) are at increased risk of bloodstream infections and sepsis-related death. CVC-related bloodstream infections (CRBSIs) are costly and account for a significant proportion of hospital-acquired infections. The aim of this audit was to assess current practice and staff knowledge of CVC post-insertion care and therefore identify aspects of CVC care with potential for improvement. We conducted a prospective audit over 28 consecutive days at a university teaching hospital investigating current practice of CVC post-insertion care in wards with high CVC usage. A multiple choice questionnaire on best practice of CVC insertion and care was distributed among clinical staff. Rates of breaches in catheter care and CRBSIs were calculated and statistical significance assumed when P<0.05. Data was recorded from 151 CVCs in 106 patients giving a total of 721 catheter days. In all, 323 breaches in care were identified giving a failure rate of 44.8%, with significant differences between intensive care unit (ICU) and non-ICU wards (P<0.001). Dressings (not intact) and caps and taps (incorrectly placed) were identified as the major lapses in CVC care with 158 and 156 breaches per 1000 catheter days, respectively. During the study period four CRBSIs were identified, producing a CRBSI rate of 5.5 per 1000 catheter days (95% confidence interval: 0.12-10.97). There are several opportunities to improve CVC post-insertion care. Future interventions to improve reliability of care should focus on implementing best practice rather than further education.

During 1997 central venous catheter type Hickman was used in nine children between two and half to eleven years old (average six years and one months). The average time of catheter placement was six months, in two cases catheter were eliminated after two and three months respectively since application (spontaneous elimination and repeated septic attacks, caused bu resistant bacterial strains). Gram-positive bacteria have been isolated with eight children (Staphylococcus aureus and Staphylococcus epidermidis), and gram-negative enterobacteriaceae (Serratia marcescens, Pseudomonas aeruginosa, Klebsiella oxytocia and pneumoniae, Escherichia coli, Salmonella group C and Enterococcus faecalis) in samples taken from the catheter and hemoculture. The central venous catheter is useful in treating oncological patients, but may cause serious consequences, like local infections or septicaemia.

    Central venous access is an important aspect of neonatal intensive care management. Malpositioned central catheters have been reported to induce cardiac tachyarrhythmia in adult populations and there are case reports within the neonatal population. We present a case of a preterm neonate with a preexisting umbilical venous catheter (UVC), who then developed a supraventricular tachycardia (SVT). This was initially treated with intravenous adenosine with transient reversion. Catheter migration was subsequently detected, with the UVC tip located within the heart. Upon withdrawal of the UVC and a final dose of adenosine, the arrhythmia permanently resolved. Our literature review confirms that tachyarrhythmia is a rare but recognised neonatal complication of malpositioned central venous catheters. We recommend the immediate investigation of central catheter position when managing neonatal tachyarrhythmia, as catheter repositioning is an essential aspect of management. PMID:28058050

    Purpose: Central venous catheters (CVC) may fail for many reasons, though 'fibrin sheaths' blocking catheter ports are usually implicated. We examined the sheaths removed from dialysis catheters to determine their histopathology.Methods: Ten catheter strippings were performed and the removed material was studied grossly and microscopically.Results: The histologic specimens showed thrombus both with and without a proteinaceous sheath.Conclusion: Dialysis catheters fail because of thrombus formation. This can occur in either the absence or presence of a protein coating on the catheter, the so-called 'fibrin sheath.'.

    Eighty used and 20 new silicone, polyurethane and polyvinylchloride central venous catheters were tested to establish the Young's modulus and the bending stiffness of the catheters and their introducers. The catheters were subjected to longitudinal traction forces and their lengthening measured. Young's modulus and the geometric moment of inertia were then calculated. It is shown that polyurethane catheters show least variation in their elastic characteristics, and that silicone catheters offer least resistance to bending and do not change their elastic properties after use. All catheters were equally unlikely to cause thrombus production if this is related to excessive bending stiffness.

    This study was designed to evaluate the usefulness of central venous access via the external jugular vein (EJV) employing Groshong catheters, and to compare the complications with those of conventional internal jugular venous catheterization. Central venous access was achieved by insertion of a single-lumen 4.0 Fr Groshong catheter via the EJV or internal jugular vein (IJV) with a single puncture. Complications associated with insertion and central venous catheter-related bloodstream infection (CVC-RBSI) were evaluated from the database. Two hundred and twenty-five patients received 400 catheters for a total period of 5377 catheter-days. Ninety-six patients underwent 201 internal jugular venous catheter (IJV-C) procedures for 2381 catheter-days, and 129 patients underwent 199 external jugular venous catheter (EJV-C) procedures for 2996 catheter-days. Use of EJV-C was associated with a longer catheter insertion length (p < .01) and period (p < .01), a larger number of operations (p < .01), and more frequent use of total parenteral nutrition (TPN) (p < .01) and less frequent use of chemotherapy (p < .01) than for IJV-C. However, there were no significant differences (NS) in complications associated with insertion and CVC-RBSI between IJV-C and EJV-C. There were no significant differences such complications as malposition, oozing or hematoma formation of insertion site, arterial bleeding, nerve damage, pneumothorax, and phlebitis between IJV-C and EJV-C. Moreover, EJV-C was not associated with morbidities such as pneumothorax, arterial bleeding, and nerve damage. Thus the study concluded that EJV-C using Groshong catheters has no severe complications and has the same rates of CVC-RBSI as conventional IJV-C for central venous access.

    Background Ultrasound guidance for continuous femoral perineural catheters may be supplemented by electrical stimulation through a needle or through a stimulating catheter. We tested the primary hypothesis that ultrasound guidance alone is noninferior on both postoperative pain scores and opioid requirement and superior on at least one of the two. Secondarily, we compared all interventions on insertion time and incremental cost. Methods Patients having knee arthroplasty with femoral nerve catheters were randomly assigned to catheter insertion guided by: 1) ultrasound alone (n=147); 2) ultrasound and electrical stimulation through the needle (n=152); or, 3) ultrasound and electrical stimulation through both the needle and catheter (n=138). Noninferiority between any two interventions was defined for pain as no more than 0.5 points worse on a 0–10 Verbal Response Scale (VRS) scale and for opioid consumption as no more than 25% greater than the mean. Results The stimulating needle group was significantly noninferior to the stimulating catheter (difference (95% CI) in mean VRS pain score [stimulating needle versus stimulating catheter] of −0.16 (−0.61, 0.29), P<0.001; percent difference in mean IV morphine equivalent dose of −5% (−25%, 21%), P=0.002) and to ultrasound only (difference in mean VRS pain score of −0.28 (−0.72, 0.16), P<0.001; percent difference in mean IV morphine equivalent dose of −2% (−22%, 25%), P=0.006). In addition, the use of ultrasound alone for femoral nerve catheter insertion was faster and cheaper than the other two methods. Conclusion Ultrasound guidance alone without adding either stimulating needle or needle/catheter combination thus appears to be the best approach to femoral perineural catheters. PMID:24758775

    The objectives of this pilot trial were to assess the safety of a new device for pulmonary embolism (PE) prophylaxis. The device, the Angel Catheter, was placed in eight patients who were in the intensive care unit and were at high risk of PE. The device was inserted at the bedside without fluoroscopic guidance via a femoral venous approach. All eight devices were inserted and subsequently retrieved without complications (follow-up, 33-36 d). One filter trapped a large clot.

  9. Central venous catheters: choosing the most appropriate access route.

    PubMed

    Hamilton, Helen

    Intravenous therapy and care is a complex and intricate area of practice, which is being subsumed into the core role of registered nurses. As more patients become recipients of a vascular access device (VAD), particularly those requiring intermediate to long-term central venous access, it is important to ensure that not only the device but also the most appropriate vein meets their clinical physiological and psychological needs. There is much research and literature on the insertion and care of central venous catheters (CVCs) as well as the detection and treatment of complications. However, apart from a few small studies comparing the performance of devices placed either in the subclavian or jugular veins, there is little to guide doctors or nurses as to which vein is preferable, if secondary complications are to be avoided. This article will describe a number of primary and secondary complications associated with both the subclavian and internal jugular veins and how these can be minimized by selecting the most appropriate vessel. The article concludes with the author's suggestions for correct patient assessment in order that the correct vein is utilized.

    A 5 year old girl with ASD was scheduled for open heart surgery. A central venous catheter was placed via the right infraclavicular vein after induction of anesthesia. Thirty minutes after insertion of the catheter, a decrease in arterial pressure and pulse pressure, an increase in heart rate and central venous pressure were observed. Cardiac tamponade was revealed by rapid opening of the chest. Gushing blood out of a hole in the right ventricular free wall was confirmed by pericardiotomy. The hemodynamics were stabilized by blood transfusion and surgical closure of the hole on the ventricle. This perforation was thought to be caused by careless insertion of a relatively stiff central venous catheter.

    Mediastinitis is a complication generally associated with thoracic surgery. Its occurrence after placement of a central venous catheter is uncommon, and only a few cases have been reported. An 83-year-old man who had mediastinitis due to extravasation of parenteral nutritional formula via a central venous catheter is presented. The signs and symptoms, diagnosis, and treatment of this unusual complication are described. This complication should be included in the differential diagnosis of mediastinitis in patients with a central venous catheter in place who have not had thoracic surgery.

    A major source of microbial colonization of short-term central venous catheters (CVC) is the patients' endogenous skin microorganisms located at the CVC insertion site. The aim of this study was to determine if a transparent film dressing incorporating a 2% (weight/weight) chlorhexidine gluconate (CHG) gel decreases CVC and insertion site microbial colonization compared with a nonantimicrobial dressing in adult patients in critical care. On CVC removal, samples for microbiological investigation were taken from both the skin surrounding the CVC insertion site and also from sutures securing the CVC. The sutures and intradermal and tip sections of the CVC were also collected for microbiological investigation. Microorganisms recovered from the samples were subsequently tested for susceptibility to CHG. There was a significant reduction in the number of microorganisms recovered from the CVC insertion site, suture site, sutures, and catheter surface in the CHG dressing group (n = 136) compared with the nonantimicrobial dressing group (n = 137). There was no significant difference in susceptibility to CHG between the microorganisms isolated from the CHG and standard dressing study patients. A film dressing incorporating a CHG gel pad significantly reduced the number of microorganisms at the CVC insertion and suture sites with concomitant reduced catheter colonization.

    The supraclavicular fossa ultrasound view can be useful for central venous catheter (CVC) placement. Venipuncture of the internal jugular veins (IJV) or subclavian veins is performed with a micro-convex ultrasound probe, using a neonatal abdominal preset with a probe frequency of 10 Mhz at a depth of 10-12 cm. Following insertion of the guidewire into the vein, the probe is shifted to the right supraclavicular fossa to obtain a view of the superior vena cava (SVC), right pulmonary artery and ascending aorta. Under real-time ultrasound view, the guidewire and its J-tip is visualized and pushed forward to the lower SVC. Insertion depth is read from guidewire marks using central venous catheter. CVC is then inserted following skin and venous dilation. The supraclavicular fossa view is most suitable for right IJV CVC insertion. If other insertion sites are chosen the right supraclavicular fossa should be within the sterile field. Scanning of the IJVs, brachiocephalic veins and SVC can reveal significant thrombosis before venipuncture. Misplaced CVCs can be corrected with a change over guidewire technique under real-time ultrasound guidance. In conjunction with a diagnostic lung ultrasound scan, this technique has a potential to replace chest radiograph for confirmation of CVC tip position and exclusion of pneumothorax. Moreover, this view is of advantage in patients with a non-p-wave cardiac rhythm were an intra-cardiac electrocardiography (ECG) is not feasible for CVC tip position confirmation. Limitations of the method are lack of availability of a micro-convex probe and the need for training.

    Bloodstream infections related to the use of central venous catheters are an important cause of patient morbidity, mortality, and increased health care costs. Catheter-related infection may be due to fibrin deposition associated with catheters. Interventions designed to decrease fibrin deposition have the potential to reduce catheter-related infections. This study was a randomized, controlled trial in which 246 patients with nontunneled central venous catheters were randomly assigned to receive a heparin-coated catheter with 50 mL/d of normal saline solution as a continuous infusion (heparin-coated group) or a noncoated catheter with a continuous infusion of low-dose unfractionated heparin (control group: continuous infusion of 100 U/kg/d). Catheter-related bloodstream infection occurred in 2.5% (3/120 catheters) in the heparin-coated group (0.9 events per 1,000 days) and in 9.1% (11/120 catheters) in the control group (3.5 events per 1,000 days; P = 0.027). No other risk factors were found for the development of catheter-related bloodstream infection. Six and seven patients experienced severe bleeding in the heparin-coated and control groups, respectively (P = 1.00). We did not observe heparin-induced thrombocytopenia. The use of heparin-coated catheters can be a safe and effective approach to the prevention of catheter-related bloodstream infection in patients with hematooncologic disease.

    Obtaining intravenous (IV) access in the emergency department (ED) can be especially challenging, and physicians often resort to placement of central venous catheters (CVCs). Use of ultrasound-guided peripheral IV catheters (USGPIVs) can prevent many "unnecessary" CVCs, but the true impact of USGPIVs has never been quantified. This study set out to determine the reduction in CVCs by USGPIV placement. This was a prospective, observational study conducted in 2 urban EDs. Patients who were to undergo placement of a CVC due to inability to establish IV access by other methods were enrolled. Ultrasound-trained physicians then attempted USGPIV placement. Patients were followed up for up to 7 days to assess for CVC placement and related complications. One hundred patients were enrolled and underwent USGPIV placement. Ultrasound-guided peripheral IV catheters were initially successfully placed in all patients but failed in 12 patients (12.0%; 95 confidence interval [CI], 7.0%-19.8%) before ED disposition, resulting in 4 central lines, 7 repeated USGPIVs, and 1 patient requiring no further intervention. Through the inpatient follow-up period, another 11 patients underwent CVC placement, resulting in a total of 15 CVCs (15.0%; 95 CI, 9.3%-23.3%) placed. Of the 15 patients who did receive a CVC, 1 patient developed a catheter-related infection, resulting in a 6.7% (95 CI, 1.2%-29.8%) complication rate. Ultrasound prevented the need for CVC placement in 85% of patients with difficult IV access. This suggests that USGPIVs have the potential to reduce morbidity in this patient population.

    The antimetabolite drug, 5-fluorouracil, inhibits microbial growth. Coating of central venous catheters with 5-fluorouracil may reduce the risk of catheter infection. Our objective was to compare the safety and efficacy of central venous catheters externally coated with 5-fluorouracil with those coated with chlorhexidine and silver sulfadiazine. Prospective, single-blind, randomized, active-controlled, multicentered, noninferiority trial. Twenty-five US medical center intensive care units. A total of 960 adult patients requiring central venous catheterization for up to 28 days. Patients were randomized to receive a central venous catheter externally coated with either 5-fluorouracil (n = 480) or chlorhexidine and silver sulfadiazine (n = 480). The primary antimicrobial outcome was a dichotomous measure (<15 colony-forming units or ≥ 15 colony-forming units) for catheter colonization determined by the roll plate method. Secondary antimicrobial outcomes included local site infection and catheter-related bloodstream infection. Central venous catheters coated with 5-fluorouracil were noninferior to chlorhexidine and silver sulfadiazine coated central venous catheters with respect to the incidence of catheter colonization (2.9% vs. 5.3%, respectively). Local site infection occurred in 1.4% of the 5-fluorouracil group and 0.9% of the chlorhexidine and silver sulfadiazine group. No episode of catheter-related bloodstream infection occurred in the 5-fluorouracil group, whereas two episodes were noted in the chlorhexidine and silver sulfadiazine group. Only Gram-positive organisms were cultured from 5-fluorouracil catheters, whereas Gram-positive bacteria, Gram-negative bacteria, and Candida were cultured from the chlorhexidine and silver sulfadiazine central venous catheters. Adverse events were comparable between the two central venous catheter coatings. Our results suggest that central venous catheters externally coated with 5-fluorouracil are a safe and effective

    Objectives The objective of this exploratory study was to find out the correlation of femoral vein diameter (FVD) to central venous pressure (CVP) measurements and to derive a prediction equation to help ascertain the fluid volume status in a critical patient. Patients and methods This was a single-centered prospective cohort study designed and conducted by the critical care department of Shifa International hospital in Islamabad, Pakistan. Patients were enrolled from the medical and surgical intensive care units. The inclusion criteria consisted of patients > 18 years of age, and an intrathoracic central venous catheterization (CVC) in place for producing CVP waveform through the transducer. Patients having contraindications to CVP placement and those unable to lie supine were excluded from the study. Critical Care fellows with sufficient training in performing venous ultrasonography measured the FVD. They were blinded to the CVP values of the same patients. Results The study included 108 patients. Among these 70/108 (64.8%) were males. Mean age was 53.85 (SD=16.74). The CVP and femoral vein diameter were measured in all patients. Mean CVP was 9.89 cmH2O (SD=3.46) and mean femoral vein diameter was 0.92 cm (SD=0.27). Multiple regression was used to generate a prediction model. FVD, age and sex of the patient were used as predictor variables to predict CVP diameter. The model was statistically significant with a p-value of < 0.000 and an F-value of 104.806. R-squared value for this model came out to be 0.744, thus the model was able to explain about 74.4% of the variance in the values observed for CVP. When controlled for age and sex, FVD was found highly correlated with CVP diameter with a p-value of < 0.000. A regression equation was derived that can be used to generate predicted values of CVP in millimeters of mercury with an R-square of 0.745 if FVD in centimeters is provided; CVP (cmH2O) = -0.039 + 10.718* FVD. Conclusions FVD was found highly correlated to

    Three patients were referred for lung ventiliation and perfusion (V/Q) imaging with symptoms strongly suggestive of pulmonary embolus (PE). Chest roentgenograms and xenon ventilation studies on all three were normal, save for prominent mediastinal silhouettes and effusions. Technetium-99m macroaggregated albumin(Tc-99m MAA), when injected through the central venous catheter (CVP), revealed mediastinal localization, whereas antecubital injections showed normal pulmonary perfusion. Contrast fluoroscopy introduced through the venous catheter in the first patient defined the extravasation. For patients under strong suspicion of PE, with a venous catheter whose distal tip is seen about the level of the heart on chest radiograph, the authors recommend administering the perfusion agent slowly through the central catheter to exclude catheter-induced complications. When extravasation is detected, injection of Tc-99m MAA by peripheral vein should be used to exclude PE.

Admitting area of a university-based high-volume trauma center. Surgical and emergency medicine residents rotating through the trauma services. An online training course on recommended sterile practices during central venous catheter insertion was developed. The course contained short video clips from actual patient care demonstrating common noncompliant behaviors and breaks regarding recommended sterile practices. A 4-month study with a counterbalanced design compared residents trained by the video-based online training course (video group) with those trained with a paper version of the course (paper group). Residents who inserted central venous catheters but received neither the paper nor video training were used as a control group. Consecutive central venous catheter insertions from 12 noon to 12 midnight except Sundays were video recorded. Sterile-practice compliance was judged through video review by two surgeons blinded to the training status of the residents. Fifty residents inserted 73 elective central venous catheters (19, 31, and 23 by the video, paper, and control group operators, respectively) into 68 patients. Overall compliance with proper operator preparation, skin preparation, and draping was 49% (36 of 73 procedures). The training had no effect on selection of site and skin preparation agent. The video group was significantly more likely than the other two groups to fully comply with sterile practices (74% vs. 33%; odds ratio, 6.1; 95% confidence interval, 2.0-22.0). Even after we controlled for the number of years in residency training, specialty, number of central venous catheters inserted, and central venous catheter site chosen, the video group was more likely to comply with recommended sterile practices (p = .003).

    The most important targets of hospital-acquired infection control are to reduce the incidence of surgical-site, catheter-related, and ventilator-associated infections. In this report, we address previously presented infection-control strategies for central venous (CV) line catheterization, using a CV catheter-related infection surveillance system. Data concerning CV catheter insertion were collected from all facilities in our 650-bed hospital, excluding the operating and hemodialysis wards. Collected data included the insertion method, purpose, length of catheter inserted, duration of catheterization, infection rate, and complication rate. Catheter-related infection was diagnosed based on bacteriological examinations from blood cultures. The total number of catheterizations was 806 a year, and average duration of catheterization was 9.8 days. The purpose of catheterization was nutritional support in 210 cases, hemodialysis in 96 cases, cardiac support in 174 cases, and other treatments in 260 cases. In 66 cases, the purpose of CV catheter was not specified. The rate of positive cultures was 7.1%, and complications other than infection occurred in 0.5%. The main causative organisms were methicillin-resistant Staphylococcus aureus (MRSA) in 38.6%, coagulase-negative Staphylococcus epidermidis (CNS) in 33.3%, and S. aureus in 12.3% of infections. Infection rates were 3.8 per 1000 catheter-days in subclavian, 6.1 in jugular, and 15.7 in femoral vein catheterization. In high-risk departments (intensive care unit [ICU] and emergency departments) the infection rate was 5.4 for subclavian and 10.2 for jugular catheterization, whereas it was 3.6 for subclavian and 4.6 for jugular catheterization in noncritical-care departments. Considering complications such as pneumothorax, CV catheterization of the jugular vein is recommended in certain situations.

    Neonatal parenteral nutrition may be delivered via peripheral cannulas or central venous catheters (umbilical or percutaneous). As the result of complications associated with umbilical catheters, many neonatal units prefer to use percutaneous catheters after initial stabilisation. Although they can be difficult to place, these catheters may be more stable than peripheral cannulae and require less frequent replacement. These delivery methods may be associated with different risks of adverse events, including acquired invasive infection and extravasation injury. To determine the effects of infusion of parenteral nutrition via percutaneous central venous catheters versus peripheral cannulae on nutrient input, growth and development and complications among hospitalised neonates receiving parenteral nutrition in terms of adverse consequences such as bacteraemia or invasive fungal infection, cardiac tamponade or other extravasation injuries. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 5), MEDLINE (1966 to June 2015) and EMBASE (1980 to June 2015), as well as conference proceedings and previous reviews. Randomised controlled trials that compared delivery of intravenous fluids (primarily parenteral nutrition) via percutaneous central venous catheters versus peripheral cannulae in hospitalised neonates. We extracted data using standard methods of the Cochrane Neonatal Group, with separate evaluation of trial quality and data extraction by two review authors. We found six trials recruiting a total of 549 infants. One trial showed that use of a percutaneous central venous catheter was associated with a smaller deficit between prescribed and actual nutrient intake during the trial period (mean difference (MD) -7.1%, 95% confidence interval (CI) -11.02 to -3.2). Infants in the percutaneous central venous catheter group needed significantly fewer catheters/cannulae (MD -4.3, 95% CI -5.24, -3.43). Meta-analysis of data from all trials

    To evaluate the indication, technical success, clinical outcome and safety of percutaneously placed totally implantable venous power ports (TIVPPs) in a femoral position in patients with contraindications to implantation in a standard position. Retrospectively, we screened our interventional radiology department database between 12/2,009 and 3/2,013 to identify 1,729 patients with a port implantation. In 8/1,729 (0.47 %) patients (1 male, 7 female, mean age 55.5 ± 9.6 years) the TIVPP was implanted via the common femoral vein with the port placed in the anterior thigh. All devices were high-pressure injectable, implanted under local anaesthesia with sonographic as well as fluoroscopic guidance, and were tunnelled subcutaneously. Indication, technical success and complications were retrospectively analysed according to the Society of Interventional Radiology (SIR) criteria. Indications were planned chemotherapy for breast (n = 6) and oesophagus cancer (n = 1) as well as need for long-term central venous access for intravenous therapy (n = 1) with a contraindication to or failed implantation in a standard position owing to central vein occlusions. Technical success was 100 %. A number of five devices were placed in the right, three in the left thigh. Altogether 1,979 catheter days were analysed. One device was explanted owing to infection after 84 days (late complication, 0.05/100 catheter days). No early complication was observed. Our data suggest that if implantation of a TIVPP is not favourable in a standard chest, upper arm or forearm position, femoral placement of the device may alternatively be used safely and with high technical success.

    The aim of this study was to investigate the in vitro and in vivo efficacy and the tissue reaction of an antibiofilm coating composed of xylitol, triclosan, and polyhexamethylene biguanide. The antimicrobial activity was analyzed by a turbidimetric method. Scanning electron microscopy was used to evaluate the antiadherent property of central venous catheter (CVC) fragments impregnated with an antibiofilm coating (I-CVC) in comparison with noncoated CVC (NC-CVC) fragments. Two in vivo assays using subcutaneous implantation of NC-CVC and I-CVC fragments in the dorsal area of rats were performed. The first assay comprised hematological and microbiological analysis. The second assay evaluated tissue response by examining the inflammatory reactions after 7 and 21 days. The formulation displayed antimicrobial activity against all tested strains. A biofilm disaggregation with significant reduction of microorganism's adherence in I-CVC fragments was observed. In vivo antiadherence results demonstrated a reduction of early biofilm formation of Staphylococcus aureus ATCC 25923, mainly in an external surface of the I-CVC, in comparison with the NC-CVC. All animals displayed negative hemoculture. No significant tissue reaction was observed, indicating that the antibiofilm formulation could be considered biocompatible. The use of I-CVC could decrease the probability of development of localized or systemic infections.

    In a intensive care unit (ICU) there are many factors that can lead to the occurrence of adverse events. A high percentage of these events are associated with the administration of drugs. Diagnostic tests, such as computed tomography, is common in critically ill patients and technique can be performed with injection of contrast agent to enhance the visualization of soft tissue. The contrast is a medication and the nurse is responsible for its proper administration. The management of the critically ill patient is complex. ICU team and radiology shares responsibility for the care and safety of the patient safety during the transfer and performing tests with contrast. The World Health Organisation patient safety strategies, recommends analysing errors and learning from them. Therefore, it was decided to investigate the causes of the category E severity adverse events that occurred in a patient who was admitted to the ICU for septic shock of abdominal origin. An abdominal computed tomography was performed with contrast which was injected through a central venous catheter. The contrast did not appear in the image. What happened? Causal analysis helped to understand what triggered the event. A care plan and an algorithm were drafted to prevent it from happening again, with the following objectives: improving knowledge, skills and promoting positive attitudes towards patient safety, working at primary, secondary and tertiary care levels.

    This report presents our experience using double-lumen, silicone rubber, indwelling central venous catheters with a subcutaneous Dacron cuff as access for hemodialysis. Twenty-seven catheters were placed in 27 patients through venous cutdowns. A 10-cm subcutaneous tunnel was created leaving the Dacron cuff 2 cm from the external exit. Sixteen Raaf catheters (lumen diameter [LD], 1 mm), three double-lumen Hickman catheters (LD, 1.6 mm) and eight HemoCath catheters (LD, 2 mm) were used. The tip of the catheter was positioned fluoroscopically in either the superior vena cava or the right atrium. One hundred fifty-nine treatments were done with the Raaf catheters (mean blood flow [MBF], 188.1 +/- 26.4 mL/min); two of these catheters became obstructed and could not be used further. Three double-lumen Hickman catheters were used in 12 hemodialysis treatments (MBF, 216.3 +/- 27.1 mL/min). One hundred fifty-five treatments were done using the HemoCath catheters (MBF, 236.7 +/- 5.5 mL/min). The degree of recirculation of these catheters was 8.56% +/- 4.34%. The major advantages of this modality include simplicity of introduction, lack of serious complications, no sacrifice of major arteries, no need for venipuncture, and potential use in either short- or long-term hemodialysis.

    Infection is the most common problem with central venous catheters (CVCs) in neonates. There are two published guidelines, including the Centers for Disease Control and Prevention (CDC), for the prevention of intravascular catheter-related infection that describes evidence-based practice to reduce nosocomial infection. Our aims were to survey current medical and nursing management of central venous catheters in tertiary neonatal intensive care units in Australia and New Zealand and to compare with the CDC evidence-based practice guideline. A cross sectional survey was performed across 27 Australian and New Zealand neonatal units in September 2012. Two web-based questionnaires were distributed, one to medical directors related to the insertion of CVCs while CVC "maintenance" surveys were sent to nurse unit managers. Seventy percent (19/27) medical management and 59% (16/27) on nursing management surveys were completed. In all neonatal intensive care units (NICUs) there were guidelines for CVC maintenance and for 18 out of 19 there were guidelines for insertion. In the seven units using femoral lines, three had a guideline on insertion and four for maintenance. CVC insertion was restricted to credentialed staff in 57.9% of neonatal units. Only 26.5% used full maximal sterile barriers for insertion. Skin disinfection practices widely varied. Dressing use and dressing change regimens were standardised; all using a semi-permeable dressing. Duration of cleaning time of the access point varied significantly; however, the majority used a chlorhexidine with alcohol solution (68.8%). Line and fluid changes varied from daily to 96 h. The majority used sterile gloves and a sterile dressing pack to access the CVC (68.8%). In the majority of NICUs stopcocks were used (62.5%) with a needle-less access point attached (87.5%). In less than 50% of NICUs education was provided on insertion and maintenance. There is diversity of current practices and some aspects vary from the CDC

    Umbilical venous catheter (UVC) is widely used in neonatal intensive care units. Pericardial effusion is an uncommon but life-threatening complication; and tamponade have been reported in 3% of neonates having such catheters. We present a case of cardiac tamponade as a complication of venous catheter in a neonate. The patient was diagnosed at the appropriate time by echocardiography and the pericardiocentesis was performed, and after removal of the complete pericardial effusion,an improvement of the critical condition was achieved. It is important to document the optimal positioning of UVC before the start of infusions.

    Long-term central venous catheters are essential for the management of chronic medical conditions, including childhood cancer. Catheter occlusion is associated with an increased risk of subsequent complications, including bloodstream infection, venous thrombosis, and catheter fracture. Therefore, predicting and pre-emptively treating occlusions should prevent complications, but no method for predicting such occlusions has been developed. We conducted a prospective trial to determine the feasibility, acceptability, and efficacy of catheter-resistance monitoring, a novel approach to predicting central venous catheter occlusion in pediatric patients. Participants who had tunneled catheters and were receiving treatment for cancer or undergoing hematopoietic stem cell transplantation underwent weekly catheter-resistance monitoring for up to 12 weeks. Resistance was assessed by measuring the inline pressure at multiple flow-rates via a syringe pump system fitted with a pressure-sensing transducer. When turbulent flow through the device was evident, resistance was not estimated, and the result was noted as "non-laminar." Ten patients attended 113 catheter-resistance monitoring visits. Elevated catheter resistance (>8.8% increase) was strongly associated with the subsequent development of acute catheter occlusion within 10 days (odds ratio = 6.2; 95% confidence interval, 1.8-21.5; p <0.01; sensitivity, 75%; specificity, 67%). A combined prediction model comprising either change in resistance greater than 8.8% or a non-laminar result predicted subsequent occlusion (odds ratio = 6.8; 95% confidence interval, 2.0-22.8; p = 0.002; sensitivity, 80%; specificity, 63%). Participants rated catheter-resistance monitoring as highly acceptable. In this pediatric hematology and oncology population, catheter-resistance monitoring is feasible, acceptable, and predicts imminent catheter occlusion.

    This study aimed to investigate the causes and managements of the fractures and migrations of the implantable venous access port catheter (IVAPC). The fracture or migration of IVAPC occurred in 4 patients who were treated between May 2012 and January 2014 in Union Hospital, Wuhan, China. The port catheter leakage was found in 2 cases during drug infusion. Catheters that dislodged to the superior vena cava and right atrium were confirmed by port angiogram. The two dislodged catheters were successfully retrieved by interventional procedures. Catheter fracture occurred in two cases during port removal. One catheter was eventually removed from the subclavian vein through right clavicle osteotomy and subclavian venotomy, and the other removed by external jugular venotomy. Flushing the port in high pressure and injury of the totally implantable venous access port (TIVP) during implantation are usually responsible for catheter displacement. Interventional retrieval procedure can be used if the catheter dislodges to the vena cava and right atrium. Catheter fracture may occur during removal if clipping syndrome occurs or the catheter is sutured very tight during implantation.

    Tunneled central venous catheters (CVC) were developed five decades ago. Since then, several clinician-inventors have created a variety of catheters with different functions. Indeed, many catheters have been named after their inventor. Many have wondered who the inventors were of each catheter, and what specifically inspired their inventions. Many of these compelling stories have yet to be told. A literature review of common catheters and personal communication with inventors. Only first person accounts from inventors or those close to the invention were used. CVCs are now essential devices that have saved countless lives. Though the inventors have earned the honor of naming their catheters, it may be reasonable to consider more consistent terminology to describe these catheters to avoid confusion.

    A 50's underwent gastrectomy for gastric cancer 4 years before. He had received chemotherapy for para-aortic lymph node metastases. A central venous catheter with a subcutaneous port was implanted via the right subclavian vein, under ultrasonographic guidance, 1 year 3 months earlier. The patient complained of swelling in his right chest during intravenous injection of ramucirumab and paclitaxel via the port. A chest radiograph revealed that a catheter fracture. A CT scan showed that the fractured catheter had lacerated the pectoralis minor muscle and the tip was in the right inferior pulmonary artery. The catheter fragment was removed using a pigtail catheter and a snare catheter via a percutaneous transfemoral approach, without any complication. The catheter was cut at 15.5 cm from the tip. This fracture was thought to be caused by a kink in the pectoralis muscle.

    Catheter fracture represents a rare problem among non-infectious complications following the insertion of totally implantable long-term central venous access systems for the application of chemotherapeutic agents. A literature survey revealed a total incidence of catheter fractures of 0-2.1%. Imminent catheter fracture can be identified radiologically, using different degrees of catheter narrowing between the clavicle and the first rib, called pinch-off sign. Two cases of catheter fracture are described and potential causes are discussed. Recommendations to avoid the pinch-off sign with the subsequent risk of catheter fracture and migration include a more lateral and direct puncture of the subclavian vein. In case of catheter narrowing in the clavicular-first rib angle, patients should be followed carefully by chest X-rays every 4 weeks. Whenever possible, the system should be removed within 6 months following insertion.

    Ilio-femoral deep vein thrombosis (DVT) has a high rate of long-term morbidity in the form of the postthrombotic syndrome (PTS). Therefore, management of acute thrombosis should not only focus on the prevention of acute complications such as propagation or embolisation of the initial clot but also on preventing PTS and recurrent thrombosis. Contemporary catheter-based treatments of deep vein thrombosis have proven to be safe and effective in selected patients. Current guidelines recommend medical therapy with anticoagulation alone for all but the most severe, limb-threatening thrombosis. They additionally allow for consideration of catheter-based treatment in patients with acute DVT and low risk of bleeding complications to prevent PTS. Recent studies favoring interventional therapy have not been included in these guidelines. Data on long-term outcome is expected to be published soon, clarifying and very likely strengthening the role of catheter-based treatments in the management of acute ilio-femoral DVT.

    In a young adult patient having situs solitus with dextrocardia the attempted pulmonary artery catheter placement for emergency mitral valve replacement required an unduly long length (50cm) of catheter insertion to get into right ventricle and then into pulmonary artery. Although catheter coiling was suspected initially, chest x-ray taken after successfully placement revealed an uncommon congenital anomalous venous connection i.e. right internal jugular opening into left sided superior vena cava then into inferior vena cava after running all along the left border of the heart. With the result, it required to pass 50cm of PA catheter to get into right ventricle in our patient. This emphasizes the need to look for abnormal venous connections during echocardiography and x-ray screening in congenital heart disease. Fluoroscopy is recommended when an unusual length of pulmonary artery catheter insertion is required to enter the pulmonary artery.

    Background Central venous catheter (CVC) and hemodialysis (HD) catheter usage are associated with complications that occur during catheter insertion, dwell period, and removal. This study aims to identify and describe the incidence rates of catheter-related complications in a large patient population in a United States-based health care claims database after CVC or HD catheter placement. Methods Patients in the i3 InVision DataMart® health care claims database with at least 1 CVC or HD catheter insertion claim were categorized into CVC or HD cohorts using diagnostic and procedural codes from the US Renal Data System, American College of Surgeons, and American Medical Association’s Physician Performance Measures. Catheter-related complications were identified using published diagnostic and procedural codes. Incidence rates (IRs)/1000 catheter-days were calculated for complications including catheter-related bloodstream infections (CRBSIs), thrombosis, embolism, intracranial hemorrhage (ICH), major bleeding (MB), and mechanical catheter–related complications (MCRCs). Results Thirty percent of the CVC cohort and 54% of the HD cohort had catheter placements lasting <90 days. Catheter-related complications occurred most often during the first 90 days of catheter placement. IRs were highest for CRBSIs in both cohorts (4.0 [95% CI, 3.7-4.3] and 5.1 [95% CI, 4.7-5.6], respectively). Other IRs in CVC and HD cohorts, respectively, were thrombosis, 1.3 and 0.8; MCRCs, 0.6 and 0.7; embolism, 0.4 and 0.5; MB, 0.1 and 0.3; and ICH, 0.1 in both cohorts. Patients with cancer at baseline had significantly higher IRs for CRBSIs and thrombosis than non-cancer patients. CVC or HD catheter–related complications were most frequently seen in patients 16 years or younger. Conclusions The risk of catheter-related complications is highest during the first 90 days of catheter placement in patients with CVCs and HD catheters and in younger patients (≤16 years of age) with HD

    More than 2.1 million central venous catheters are placed annually. While carotid artery cannulation is rare, its effects can be devastating. Anesthesia providers frequently work with central venous catheters in the perioperative setting. Therefore, it is imperative that they be able to identify and react appropriately to carotid artery injury both in preexisting central lines and those that they have placed. This case report details a case of accidental carotid artery catheterization during attempted right internal jugular vein catheterization and the steps taken to treat the patient following its recognition. A discussion of technique for central venous catheterization, indications for suspicion of arterial puncture, methods for confirming venous or arterial placement, appropriate methods for management of carotid artery cannulation, and the benefit of ultrasound in central venous cannulation follow. Through the appropriate use of equipment, early detection and management of carotid artery injury, and proper training, patient outcomes may be improved.

    Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down." A separate exit site is then created for the new catheter and it is tunneled to the "cut-down" site per routine. The non-functioning catheter is then removed from the surgical field. The proximal fibrous sheath is finally cannulated either directly with the new catheter or with a wire/dilator system. This technique effectively re-uses the same venous access point while allowing for a complete change of the physical line and external site. Twenty attempts at this technique were made in twelve patients; six patients underwent the site re-utilization procedure multiple times. Re-using the fibrous tunnel to re-cycle the internal catheter site was successful in seventeen of twenty attempts. All patients had chronic conditions leading to difficult long-term central venous access [short bowel syndrome (6), hemophilia (2), cystic fibrosis (1), chronic need for central IV access (3)]. Indications for catheter replacement included catheter occlusion/mechanical failure/breakage (9), dislodgement (6), infection (1), and inadequate catheter length due to patient growth (4). Broviac/Hickman catheter sites were most commonly re-used (13; one failure); re-using a portcath site was successful in 5 of 7 attempts. There were no short term infections or mechanical complications. We describe a novel technique for salvaging tunneled central venous catheter access sites. This technique is well suited

    It is unknown if central venous catheters bypass the skin's electrical resistance and engender a risk of nerve conduction study-induced cardiac arrhythmia. The objective of this study is to determine if nerve conduction studies affect cardiac conduction and rhythm in patients with central venous catheters. Under continuous 12-lead electrocardiogram monitoring, subjects with and without central venous catheters underwent a series of upper extremity nerve conduction studies. A cardiologist reviewed the electrocardiogram tracings for evidence of cardiac conduction abnormality or arrhythmia. Ten control subjects and 10 subjects with central venous catheters underwent the nerve conduction study protocol. No malignant arrhythmias or conduction abnormalities were noted in either group. Nerve conduction studies of the upper extremities, including both proximal stimulation and repetitive stimulation, do not appear to confer increased risk of cardiac conduction abnormality in those patients with central venous catheters who are not critically ill or have a prior history of arrhythmia.

    2013-01-01

    Background Central venous catheter-associated bloodstream infections in children are an increasingly recognized serious safety problem worldwide, but are often preventable. Central venous catheter bundles have proved effective to prevent such infections. Successful implementation requires changes in the hospital system as well as in healthcare professionals’ behaviour. The aim of the study is to evaluate process and outcome of implementation of a state-of-the-art central venous catheter insertion and maintenance bundle in a large university children’s hospital. Methods/design An interrupted time series design will be used; the study will encompass all children who need a central venous catheter. New state-of-the-art central venous catheter bundles will be developed. The Pronovost-model will guide the implementation process. We developed a tailored multifaceted implementation strategy consisting of reminders, feedback, management support, local opinion leaders, and education. Primary outcome measure is the number of catheter-associated infections per 1000 line-days. The process outcome is degree of adherence to use of these central venous catheter bundles is the secondary outcome. A cost-effectiveness analysis is part of the study. Outcomes will be monitored during three periods: baseline, pre-intervention, and post-intervention for over 48 months. Discussion This model-based implementation strategy will reveal the challenges of implementing a hospital-wide safety program. This work will add to the body of knowledge in the field of implementation. We postulate that healthcare workers’ willingness to shift from providing habitual care to state-of-the-art care may reflect the need for consistent care improvement.

    Context: Central venous catheter-related bloodstream infection (CRBSI) is associated with high rates of morbidity and mortality in critically ill patients. Aims: This study was conducted to determine the incidence of central venous catheter-related infections (CRIs) and to identify the factors influencing it. So far, there are very few studies that have been conducted on CRBSI in the intensive care unit in India. Settings and Design: This was a prospective, observational study carried out in the medical intensive care unit (MICU) over a period of 1 year from January to December 2004. Materials and Methods: A total of 54 patients with indwelling central venous catheters of age group between 20 and 75 years were included. The catheters were cultured using the standard semiquantitative culture (SQC) method. Statistical analysis used SPSS-10 version statistical software. Results: A total of 54 CVC catheters with 319 catheter days were included in this study. Of 54 patients with CVCs studied for bacteriology, 39 (72.22%) catheters showed negative SQCs and also negative blood cultures. A total of 15 (27.77%) catheters were positive on SQC, of which 10 (18.52%) were with catheter-associated infection and four (7.41%) were with catheter-associated bacteremia; the remaining one was a probable catheter-associated bacteremia. CRIs were high among catheters that were kept in situ for more than 3 days and emergency procedures where two or more attempts were required for catheterization (P < 0.05). In multivariate analysis of covariance duration of catheter in situ for >3 days, inexperienced venupucturist, more number of attempts and emergency CVC were associated with more incidence of CVCBSIs, with P <0.02. The duration of catheter in situ was negatively correlated (-0.53) and number of attempts required to put CVC was positively correlated (+0.39) with incidence of CVCBSIs. Sixty-five percent of the isolates belonged to the CONS group (13/20). Staphylococcus epidermidis showed

Other fields requiring high reliability have used Failure Mode and Effects Analysis (FMEA) to prioritize quality and safety improvement efforts. To use FMEA in the development of a formal, standardized curriculum for central venous catheter training. We surveyed interns regarding their prior experience with central venous catheter placement. A multidisciplinary team used FMEA to identify high-priority failure modes and to develop online and hands-on training modules to decrease the frequency, diminish the severity, and improve the early detection of these failure modes. We required new interns to complete the modules and tracked their progress using multiple assessments. Survey results showed new interns had little prior experience with central venous catheter placement. Using FMEA, we created a curriculum that focused on planning and execution skills and identified 3 priority topics: (1) retained guidewires, which led to training on handling catheters and guidewires; (2) improved needle access, which prompted the development of an ultrasound training module; and (3) catheter-associated bloodstream infections, which were addressed through training on maximum sterile barriers. Each module included assessments that measured progress toward recognition and avoidance of common failure modes. Since introducing this curriculum, the number of retained guidewires has fallen more than 4-fold. Rates of catheter-associated infections have not yet declined, and it will take time before ultrasound training will have a measurable effect. The FMEA provided a process for curriculum development. Precise definitions of failure modes for retained guidewires facilitated development of a curriculum that contributed to a dramatic decrease in the frequency of this complication.

    Fourteen severely ill ventilated patients in an intensive care unit, requiring short-term total parenteral nutrition, were examined for catheter-related infection. Microbiological analysis using Maki's SQ technique was carried out on catheter exit site, catheter hub, proximal subcutaneous segment of catheter and catheter up. Qualitative cultures were carried out on total parenteral nutrition and peripheral blood samples. Twenty six of 29 catheters removed (90%) were culture positive but only 7 catheters were related to positive blood cultures, giving a catheter-related bacteremia (CRB) rate of 24%. Haematogenous seeding was strongly implicated in 7/29 (24%) of catheters. Patients' skin flora appeared to be the main source of catheter-related infection. The organisms isolated for patients with CRB included coagulase-negative staphylococci, Acinetobacter and Klebsiella. It is suggested that to control infective complications of central venous catheters, emphasis should be focused on specialised intravenous therapy teams and the use of strict protocols for insertion and care of central lines.

    Infraclavicular and internal jugular catheterization are commonly used techniques for hemodialysis access, but may at times be impeded in patients whose anatomy makes cannulation difficult. In an effort to enlarge the spectrum of alternative access sites, we evaluated the supraclavicular approach for large-bore catheters. During an 18-month period we prospectively collected data on success rate and major and minor complications of the supraclavicular access for conventional dialysis catheters as well as Dacron-cuffed tunneled devices in 175 adult patients admitted for various extracorporeal therapies and bone marrow transplantation. Two hundred eight large-bore catheters (99 conventional dialysis catheters, 63 semirigid tunneled Dacron-cuffed catheters, and 46 Hickman catheters) were successfully placed in 164 patients (success rate, 93.8%), 58 (33.1%) of whom had been previously catheterized. Complications included pneumothorax (one patient), arterial puncture (seven patients), and puncture of the thoracic duct (two patients) without sequelae. Postinsertional chest radiographs demonstrated impressive coaxial lie of most catheters. Catheter malpositions occurred only sporadically (1%). Difficulty of introducing the catheter via a placed sheath was rarely observed. There was no clinically significant evidence of catheter-induced venous thrombosis or stenosis. We conclude that the supraclavicular route is an easy and safe first approach for large-bore catheters, as well as a useful alternative to traditional puncture sites for precatheterized and anatomically problematic patients.

  13. Flushing and Locking of Venous Catheters: Available Evidence and Evidence Deficit

    PubMed Central

    2015-01-01

    Flushing and locking of intravenous catheters are thought to be essential in the prevention of occlusion. The clinical sign of an occlusion is catheter malfunction and flushing is strongly recommended to ensure a well-functioning catheter. Therefore fluid dynamics, flushing techniques, and sufficient flushing volumes are important matters in adequate flushing in all catheter types. If a catheter is not in use, it is locked. For years, it has been thought that the catheter has to be filled with an anticoagulant to prevent catheter occlusion. Heparin has played a key role in locking venous catheters. However, the high number of risks associated with heparin forces us to look for alternatives. A long time ago, 0.9% sodium chloride was already introduced as locking solution in peripheral cannulas. More recently, a 0.9% sodium chloride lock has also been investigated in other types of catheters. Thrombolytic agents have also been studied as a locking solution because their antithrombotic effect was suggested as superior to heparin. Other catheter lock solutions focus on the anti-infective properties of the locks such as antibiotics and chelating agents. Still, the most effective locking solution will depend on the catheter type and the patient's condition. PMID:26075094

    To evaluate the accuracy of the simultaneous analysis of three radiographic anatomical landmarks - diaphragm, cardiac silhouette, and vertebral bodies - in determining the position of the umbilical venous catheter distal end using echocardiography as a reference standard. This was a cross-sectional, observational study, with the prospective inclusion of data from all neonates born in a public reference hospital, between April 2012 and September 2013, submitted to umbilical venous catheter insertion as part of their medical care. The position of the catheter distal end, determined by the simultaneous analysis of three radiographic anatomical landmarks, was compared with the anatomical position obtained by echocardiography; sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. Of the 162 newborns assessed by echocardiography, only 44 (27.16%) had the catheter in optimal position, in the thoracic portion of the inferior vena cava or at the junction of the inferior vena cava with the right atrium. The catheters were located in the left atrium and interatrial septum in 54 (33.33%) newborns, in the right atrium in 26 (16.05%), intra-hepatic in 37 (22.84%), and intra-aortic in-one newborn (0.62%). The sensitivity, specificity and accuracy of the radiography to detect the catheter in the target area were 56%, 71%, and 67.28%, respectively. Anteroposterior radiography of the chest alone is not able to safely define the umbilical venous catheter position. Echocardiography allows direct visualization of the catheter tip in relation to vascular structures and, whenever possible, should be considered to identify the location of the umbilical venous catheter.

    Long-term central venous catheters (CVC) facilitate care for patients with chronic illnesses, but catheter occlusions and catheter-related thrombosis (CRT) are common complications. This review summarizes management of CVC and CRT. Mechanical CVC occlusions require cause-specific therapy; whereas, thrombotic occlusions usually resolve with thrombolytic therapy, such as alteplase. Prophylaxis with thrombolytic flushes may decrease CVC infections and CRT, but confirmatory studies and cost-effectiveness analysis are needed. Risk factors for CRT include previous catheter infections, malposition of the catheter tip, and prothrombotic states. CRT can lead to catheter infection, pulmonary embolism, and post-thrombotic syndrome. CRT is diagnosed primarily using Doppler ultrasound or venography and treated with anticoagulation for 6 weeks to a year, depending on the extent of the thrombus, response to initial therapy, and whether thrombophilic factors persist. Prevention of CRT includes proper positioning of the CVC and prevention of infections; anticoagulation prophylaxis is not recommended at present. PMID:19595350

    Abnormal origin of right coronary artery (RCA) is not uncommon. The incidence is .25-.92%. Right Judkin catheter is used universally for engaging right coronary ostium from femoral route. We have tried Tiger catheter from femoral route in abnormal origin of RCA patients. We were successful in cannulating RCA ostium in most of the cases. We have studied about 5120 patients over 4 years. We have selected patients from November 2010 to November 2014. Our patients are from two institutions-I.P.G.M.E.R., Kolkata and Burdwan Medical College, West Bengal. Right Judkin 3.5 and 4 were used universally. We have used AL-1,2,3, AR1,2, multipurpose, different guide catheters for cannulating RCA ostium in those cases where we failed to engage by right Judkin catheter. We have used Tiger catheter as a last resort when all endeavor failed. Among 40 cases of left sinus origin Type A-9, Type B-14, Type C-6, Type D-3, and Type E-8 patients were observed. But 668 cases abnormal origin of RCA were from right coronary sinus only. High take-off origin were 422 cases (8%), low take-off were 132 cases (2.5%), and posterior origin were 114 cases (2%). We could engage right coronary ostium by Tiger catheter in 690 cases (97%). We failed in 23 cases (3%). Tiger catheter can be used successfully in abnormal RCA origin cases.

    Central venous catheter insertions may lead to preventable adverse events. Attending physicians' central venous catheter insertion skills are not assessed routinely. We aimed to compare attending physicians' simulated central venous catheterinsertion performance to published competency standards. Prospective cohort study of attending physicians' simulated internal jugular and subclavian central venous catheter insertion skills versus a historical comparison group of residents who participated in simulation training. Fifty-eight Veterans Affairs Medical Centers from February 2014 to December 2014 during a 2-day simulation-based education curriculum and two academic medical centers in Chicago. A total of 108 experienced attending physicians and 143 internal medicine and emergency medicine residents. None. Using a previously published central venous catheter insertion skills checklist, we compared Veterans Affairs Medical Centers attending physicians' simulated central venous catheter insertion performance to the same simulated performance by internal medicine and emergency medicine residents from two academic centers. Attending physician performance was compared to residents' baseline and posttest (after simulation training) performance. Minimum passing scores were set previously by an expert panel. Attending physicians performed higher on the internal jugular (median, 75.86% items correct; interquartile range, 68.97-86.21) and subclavian (median, 83.00%; interquartile range, 59.00-86.21) assessments compared to residents' internal jugular (median, 37.04% items correct; interquartile range, 22.22-68.97) and subclavian (median, 33.33%; interquartile range, 0.00-70.37; both p < 0.001) baseline assessments. Overall simulated performance was poor because only 12 of 67 attending physicians (17.9%) met or exceeded the minimum passing score for internal jugular central venous catheter insertion and only 11 of 47 (23.4%) met or exceeded the minimum passing score for

    Central venous catheters are a popular choice for the initiation of hemodialysis or for bridging between different types of access. Despite this, they have many drawbacks including a high morbidity from thrombosis and infection. Advances in technology have allowed placement of these lines relatively safely, and national guidelines have been established to help prevent complications. There is an established algorithm for location and technique for placement that minimizes harm to the patient; however, there are significant short- and long-term complications that proceduralists who place catheters should be able to recognize and manage. This review covers insertion and complications of central venous catheters for hemodialysis, and the social and economic impact of the use of catheters for initiating dialysis is reviewed.

    Cellulosimicrobium cellulans (formerly known as Oerskovia xanthineolytica) rarely causes human infection. Infections have been reported in immunocompromised hosts or in patients with foreign bodies, such as catheters, where treatment has generally involved removal of the foreign body. We report on a case in which the organism was isolated in multiple blood cultures from a 13-year-old male. After initial therapy failed, treatment with vancomycin and rifampin resulted in infection clearance without removal of the central venous catheter. PMID:16825406

    The incidence of acute kidney injury (AKI) is estimated at 10 to 20% in patients admitted to intensive care units (ICU) and often requires renal replacement therapy (RRT). ICU mortality in AKI patients can exceed 50%. Venous catheters are the preferred vascular access method for AKI patients requiring RRT, but carry a risk of catheter thrombosis or infection. Catheter lock solutions are commonly used to prevent such complications. Heparin and citrate locks are both widely used for tunneled, long-term catheters, but few studies have compared citrate versus heparin for patients with short-term, non-tunneled catheters. We aim to compare citrate 4% catheter lock solution versus heparin in terms of event-free survival of the first non-tunneled hemodialysis catheter inserted in ICU patients with AKI requiring RRT. Secondary objectives are the rate of fibrinolysis, incidence of catheter thrombosis and catheter-related infection per 1,000 catheter days, length of stay in ICU and in-hospital and 28-day mortality. The VERROU-REA study is a randomized, prospective, multicenter, double-blind, parallel-group, controlled superiority study carried out in the medical, surgical and nephrological ICUs of two large university hospitals in eastern France. A catheter lock solution composed of trisodium citrate at 4% will be compared to unfractionated heparin at a concentration of 5,000 IU/mL. All consecutive adult patients with AKI requiring extracorporeal RRT, and in whom a first non-tunneled catheter is to be inserted by the jugular or femoral approach, will be eligible. Catheters inserted by the subclavian approach, patients with acute liver failure, thrombopenia or contraindication to systemic anticoagulation will be excluded. Patients will be followed up daily in accordance with standard practices for RRT until death or discharge. Data is scarce regarding the use of non-tunneled catheters in the ICU setting in patients with AKI. This study will provide an evidence base for

Medical intensive care unit and Surgical/Burn/Trauma intensive care unit at Barnes-Jewish Hospital, St. Louis, MO. Three hundred forty-one patients with multilumen central venous catheters. Patients with at least one lumen with a minimum of two flushes were included in the analysis. Patients were randomly assigned within 12 hrs of central venous catheter insertion to receive either heparin or 0.9% sodium chloride flush. The primary outcome was lumen nonpatency. Secondary outcomes included the rates of loss of blood return, inability to infuse or flush through the lumen (flush failure), heparin-induced thrombocytopenia, and catheter-related blood stream infection. Assessment for patency was performed every 8 hrs in lumens without continuous infusions for the duration of catheter placement or discharge from intensive care unit. Three hundred twenty-six central venous catheters were studied yielding 709 lumens for analysis. The nonpatency rate was 3.8% in the heparin group (n = 314) and 6.3% in the 0.9% sodium chloride group (n = 395) (relative risk 1.66, 95% confidence interval 0.86-3.22, p = .136). The Kaplan-Meier analysis for time to first patency loss was not significantly different (log rank = 0.093) between groups. The rates of loss of blood return and flush failure were similar between the heparin and 0.9% sodium chloride groups. Pressure-injectable central venous catheters had significantly greater rates of nonpatency (10.6% vs. 4.3%, p = .001) and loss of blood return (37.0% vs. 18.8%, p <.001) compared to nonpressure-injectable catheters. The frequencies of heparin-induced thrombocytopenia and catheter-related blood stream infection were similar between groups. 0.9% sodium chloride and heparin flushing solutions have similar rates of lumen nonpatency.

The main species isolated in the lumen were 50% coagulase-negative Staphylococcus, 14.3% Staphylococcus aureus, and 14.3% Pseudomonas aeruginosa. Fifty nine percent of multidrug-resistant bacteria were isolated of the three-way stopcocks, 42% of the lumens, and 44% of the dressing with a predominance of coagulase-negative Staphylococcus resistant to methicillin. Besides, 18% gram-negative bacteria with resistance to carbapenems were identified from multidrug-resistant bacteria on the external surfaces of the three-way stopcocks. it is important to emphasize the isolation of coagulase-negative Staphylococcus and gram-negative bacteria resistant to methicillin and carbapenems in samples of devices, respectively, which reinforces the importance of nursing care in the maintenance of the biologically safe environment as well as prevention and infection control practices. avaliar o uso de cateteres venosos periféricos com base em análises microbiológicas de dispositivos (curativos e torneiras de três vias - T3Vs) e assim contribuir para a prevenção e controle de infecção. estudo prospectivo de análise microbiológica de 30 T3Vs (superfícies externas e lúmens) e 30 curativos utilizados na manutenção dos cateteres venosos periféricos de pacientes adultos hospitalizados. todas as superfícies externas, 40% dos lúmens e 86,7% dos curativos apresentaram crescimento bacteriano.

    Although it can be prevented, catheter-related bacteremia is common and dangerous. The antiseptics most widely used during insertion of peripheral venous catheters (PVCs) include povidone iodine, alcohol, and chlorhexidine. Another widely used antiseptic is a solution of 0.057 g sodium hypochlorite. This pilot study explored the contamination rate of the PVC tip inserted after skin decontamination with sodium hypochlorite. Culture analysis of the tips of the PVCs inserted into the 42 participants showed 7 (16.7%) colonized catheters. The results of this pilot study suggest taking into serious consideration the assessment of this antiseptic in randomized experimental studies.

    This was a systematic review of the incidence density and risk factors for central venous catheter-related infections in a neonatal population. The MEDLINE, Embase, Cochrane, BDENF, SciELO, and LILACS databases were used without date or language restriction. Studies that analyzed risk factors for bloodstream infections in newborns were identified. A total of 134 articles were found that met the eligibility criteria. Of these articles, 14 were selected that addressed risk factors for central venous catheter-related infection in neonates. Catheter-related bloodstream infections remain an important complication, as shown by the incidence rates reported in the studies included in this review. The observed risk factors indicate that low birth weight, prematurity, and longer catheter permanence are related to a higher incidence of bloodstream infections. It has been observed that low rates of catheter-related infections, i.e., close to zero, are already a reality in health institutions in developed countries, since they use infection surveillance and control programs. Catheter-related bloodstream infections still show high incidence density rates in developing countries. The authors emphasize the need for further longitudinal studies and the need for better strategies to prevent risk factors, aiming at the reduction of catheter-related infections. Copyright © 2017.

    Vascular access in paediatric patients with chronic and/or life-threatening illness is crucial to survival. Access is frequently lost in this group because of thrombosis, infection, or displacement, and vascular options can quickly be exhausted. The last resort access procedure is generally a direct atrial catheter inserted via a thoracotomy. A viable alternative is the percutaneous transhepatic Broviac catheter (Bard Access Systems, Salt Lake City, UT). We retrospectively reviewed the charts of 5 patients who underwent percutaneous transhepatic Broviac insertion for long-term access over a 4-year period in a single institution. Four of the patients (80%) had a significant cardiac abnormality, with 1 patient requiring long-term parenteral nutrition after complicated necrotizing enterocolitis. All patients had significant caval thrombosis, which precluded them having placement of a standard percutaneous or openly placed central catheter. Of the 5 patients, 2 (40%) died of cardiac-related illnesses. Of the 3 surviving patients, 2 had functioning catheters electively removed because they were no longer required. One catheter was removed at thoracotomy for right atrial perforation because of catheter erosion. Vascular access in paediatric patients with chronic and/or life-threatening illness is crucial to survival. Transhepatic central venous catheters are a feasible, reliable, and relatively easily placed form of central access in patients with multiple venous thromboses requiring long-term access. This route should be considered in paediatric patients requiring central access in preference to a thoracotomy.

    Purpose. To compare the differences in practice and outcome of all radiologically and surgically placed central venous catheters retrospectively over a 2-year period simultaneously, at a single institution. Methods.A total of 253 Hickman catheters were inserted in 209 patients; 120 were placed radiologically in 102 patients and 133 were placed surgically in 107 patients. The indication was chemotherapy in 76% of radiological and in 47% of surgical cases; the remainder were for total parenteral nutrition and venous access. Results. There were 6 (4.5%) primary surgical failures and a further 17 (13%) surgical cases requiring multiple placement attempts. Pneumothorax occurred once (0.8%) surgically and four times (3.3%) radiologically. There were no radiological primary misplacements but there were five (3.7%) surgical ones. Catheter or central vein thrombosis occurred in four (3.3%) radiological and five (3.7%) surgical cases. The rate of infection per 1000 catheter-days was 1.9 in radiologically placed catheters and 4.0 in surgically placed ones (p<0.001). Average catheter life-span was similar for the two placement methods (100{+-}23 days). Conclusion. Radiological placement is consistently more reliable than surgical placement. There are fewer placement complications and fewer catheter infections overall.

    Central venous catheters (CVCs) nowadays constitute critical devices used in medical care, namely in intensive care units. However, CVCs also represent one of the indwelling medical devices with enhanced risk of nosocomial device-related infection. Catheter-related infections (CRIs) are a major cause of patient morbidity and mortality, often justifying premature catheter removal and an increase in costs and use of resources. Adhesion and subsequent biofilm formation on the surfaces of indwelling catheters is elemental to the onset of pathogenesis. Seeking the prevention of CVC colonisation and CRI, a variety of approaches have been studied, tested and, in some cases, already applied in clinical practice. This review looks at the current preventive strategies often used to decrease the risk of CRIs due to colonization and biofilm formation on catheter surfaces, as well as at the more recent approaches under investigation.

  12. Central venous catheter "pinch-off" and fracture: a review of two under-recognized complications.

    Although uncommon, "pinch-off syndrome" and catheter fracture are reported complications of central venous catheters (CVCs). Pinch-off syndrome is characterized by intermittent catheter malfunction in conjunction with radiologic evidence of catheter compression. Warning signs of pinch-off syndrome include difficulty with-drawing blood samples and resistance to infusion of IV fluids. CVC fracture is characterized by migration of the distal catheter fragment through the heart and, often, into the pulmonary artery; it may be accompanied by the sudden onset of chest pain, palpitations, and arrhythmias. Twenty-seven cases of CVC fracture were reviewed, including 22 cases reported in the literature as well as an analysis of 5 cases that occurred at the authors' institution. Among the 22 cases reported in the literature, the average length of time between catheter insertion and fracture was 6.7 months. In 82% of these cases, the fracture occurred at the clavicle/first rib junction, where mechanical friction against the catheter has been well established as the mechanism for most fractures. In 9 of these 22 cases, evidence of catheter compression was noted on chest x-ray prior to fracture. This paper discusses assessment criteria for pinch-off syndrome and catheter fracture, as well as nursing implications regarding the prevention and early detection of these potentially serious complications.

    Central venous catheter needleless connectors (NCs) have been shown to develop microbial contamination. A protocol was developed for the collection, processing, and examination of NCs to detect and measure biofilms on these devices. Sixty-three percent of 24 NCs collected from a bone marrow transplant center contained biofilms comprised primarily of coagulase-negative staphylococci. PMID:11158143

    The insertion of Hickman central venous catheters for chronic venous access is a procedure usually conducted in the operating theatre under local or general anaesthesia. In a prospective study over a one year period we have assessed the feasibility of radiologists inserting central venous catheters for long term access. A subclavicular approach to the subclavian vein with prior digital subtraction angiography or video imaging of the vein was the technique of choice. Thirty-one Hickman catheters were inserted in 21 patients. All but two patients had a haematological malignancy. Ages ranged from 19 to 77 years. The mean time for insertion was 43 min (range 20-80 min). The catheters remained in situ for between 2 days and 242 days with a mean of 86 days. There was one documented line infection; nine patients had episodes of septicaemia with identified organisms, and a further six had pyrexias of unknown origin during the line indwelling period. There were four documented line and or ipsilateral subclavian vein thromboses, and one death occurred within 36 hours of the procedure. We conclude that radiological placement is an excellent alternative to 'blind' surgical placement. Screening during insertion provides immediate facilities for correction of malposition and monitoring of immediate complications. The time taken for catheter insertion did not impede the usual patient throughout in the interventional radiology suite.

    Intravenous prostanoid therapy is one cornerstone of therapy for patients with pre-capillary pulmonary hypertension (PH). Long-term central venous catheters expose patients to infectious complications. We report the incidence of catheter-related infection (CRI) and the spectrum of bacteria for ambulatory PH patients treated with iloprost via non-tunnelled central venous catheters from our Swiss referral centre in Zurich. Data from 15 PH patients treated with intravenous iloprost between May 2000 and June 2012 were reviewed. We found 11 CRI in 4 cases by two different organisms. Pathogens found were Brevibacterium (55%), Micrococcus luteus (18%), coagulase-negative Staphylococcus (9%) and Staphylococcus aureus (9%), as well as unusual organisms such as Agrobacterium tumefaciens or Delftia tsuruhatensis. The overall CRI rate was 1.28 per 1,000 catheter days, or 0.47 per year. The incidence of CRI using long-term, non-tunnelled central venous catheters in PH patients treated with iloprost is low. Uncommon, rare pathogens causing CRI were found in a substantial number of patients. Copyright © 2013 S. Karger AG, Basel.

    Catheter-related bloodstream infections (CRBSI) are a significant cause of morbidity and excess hospital cost. Data from prospective, randomized trials demonstrate that the risk of these infections can be minimized by simple interventions. Changing the behaviour of healthcare workers who insert and care for intravascular catheters is imperative. Creating a culture of patient safety and assuring easy access to the products necessary to maintain strict asepsis during catheter insertion, dressing changes, and when manipulating catheter hubs, will enhance adherence to optimal practice and will reduce the risk posed to the millions of patients in need of such devices.

    Objectives The purpose of this study was to test if venous blood drawn from femoral access can be used to estimate the central venous oxygen saturation and arterial lactate levels in critically ill patients. Methods Bland-Altman analysis and Spearman correlations were used to compare the femoral venous oxygen saturation and central venous oxygen saturation as well as arterial lactate levels and femoral lactate. A pre-specified subgroup analysis was conducted in patients with signs of hypoperfusion. In addition, the clinical agreement was also investigated. Results Blood samples were obtained in 26 patients. In 107 paired samples, there was a moderate correlation (r = 0.686, p < 0.0001) between the central venous oxygen saturation and femoral venous oxygen saturation with a bias of 8.24 ± 10.44 (95% limits of agreement: -12.23 to 28.70). In 102 paired samples, there was a strong correlation between the arterial lactate levels and femoral lactate levels (r = 0.972, p < 0.001) with a bias of -2.71 ± 9.86 (95% limits of agreement: -22.03 to 16.61). The presence of hypoperfusion did not significantly change these results. The clinical agreement for venous saturation was inadequate, with different therapeutic decisions in 22.4% of the situation; for lactate, this was the case only in 5.2% of the situations. Conclusion Femoral venous oxygen saturation should not be used as a surrogate of central venous oxygen saturation. However, femoral lactate levels can be used in clinical practice, albeit with caution. PMID:26761471

    The extensive use of central venous catheters (CVC) in a hospital environment leads to increased iatrogenic complications, as more catheters are used enclosed and its maintenance is prolonged. Several complications are known to be related to central venous catheter, of which the uncommon cardiac tamponade (CT), hardly recognized and associated with high mortality. We present a clinical case, with favorable outcome, of a patient who developed a CT 17 days after CVC placement, and try to reflect on the measures that can be taken to reduce its incidence, as well as the therapeutic approaches to practice in the presence of a suspected CT.

    2014-10-01

    Central venous catheters (CVC) play an essential role in the management of cancer patients. Venous thrombosis is a common complication of CVC. The incidence of CVC-associated venous thromboembolism (CVC-VTE) is 1.7 per 1000 catheter days. Risk factors for CVC-VTE include the patient's underlying cancer, a history of previous thrombotic events and the location and type of CVC. Anticoagulant prophylaxis is not effective for CVC-VTE. Anticoagulation alone is the preferred initial treatment for CVC-VTE. CVC removal may be considered in refractory cases or when anticoagulation is contraindicated. Thrombolytic therapy is reserved for patients with limb-threatening thrombosis or thrombosis unresponsive to conventional treatment. Anticoagulation should be continued for at least 3 months or as long as the CVC is present.

    The aim of this study is to compare the complication rates of three vascular access devices in patients with solid tumours having infusion chemotherapy. An observational study of 58 central venous catheter (CVC) lines inserted in 55 patients with solid tumours requiring infusional chemotherapy was performed. The study was conducted between January 2011 and August 2013, looking at complication and infection rates as primary outcomes. Data were recorded from patients with 19 tunnelled cuffed silicone catheters, nine with peripherally inserted central catheters (PICCs) and 30 central venous ports. The two CVC groups (ports and non-ports) matched equally in terms of tumour site; all patients with solid tumours were included, haematology patients were excluded and chemotherapy regimens were comparable. Thirteen out of 28 non- ports had complications compared with one out of 30 central venous ports. Ten out of 19 tunnelled catheters had complications including three displacements and seven were removed due to infection. There were no reports of line-related sepsis in the PICC or ports. Three out of nine PICC lines had complications including two displacements and one PICC blocked permanently requiring removal. In addition, one port out of 30 was removed due to erosion through the skin. There were no episodes of thrombosis or fibrin sheath formation related to any of the devices. In our study, we demonstrated that central venous ports and PICC lines in patients undergoing infusional chemotherapy had lower line infection rates than tunnelled catheters, and only ports have been shown to be almost complication-free. In addition, we found infection rates higher in CVCs s cared for by patient/carers rather than hospital only care, and higher in colorectal patients with stomas. Therefore, we recommend that central venous ports are a safe, acceptable CVC option for infusional chemotherapy for adults with solid tumours.

    Central venous catheter-related infections are a significant medical problem. Improved preventive measures are needed. To ascertain 1) effectiveness of a second-generation antiseptic-coated catheter in the prevention of microbial colonization and infection; 2) safety and tolerability of this device; 3) microbiology of infected catheters; and 4) propensity for the development of antiseptic resistance. Multicenter, randomized, double-blind, controlled trial. 9 university-affiliated medical centers. 780 patients in intensive care units who required central venous catheterization. Patients received either a standard catheter or a catheter coated with chlorhexidine and silver sulfadiazine. The authors assessed catheter colonization and catheter-related infection, characterized microbes by molecular typing, and determined their susceptibility to antiseptics. Patient tolerance of the catheter was monitored. Patients with the 2 types of catheters had similar demographic features, clinical interventions, laboratory values, and risk factors for infection. Antiseptic catheters were less likely to be colonized at the time of removal compared with control catheters (13.3 vs. 24.1 colonized catheters per 1000 catheter-days; P < 0.01). The center-stratified Cox regression hazard ratio for colonization controlling for sampling design and potentially confounding variables was 0.45 (95% CI, 0.25 to 0.78). The rate of definitive catheter-related bloodstream infection was 1.24 per 1000 catheter-days (CI, 0.26 to 3.62 per 1000 catheter-days) for the control group versus 0.42 per 1000 catheter-days (CI, 0.01 to 2.34 per 1000 catheter-days) for the antiseptic catheter group (P = 0.6). Coagulase-negative staphylococci and other gram-positive organisms were the most frequent microbes to colonize catheters. Noninfectious adverse events were similar in both groups. Antiseptic susceptibility was similar for microbes recovered from either group. The antiseptic catheter was not compared with an

    Recent advances in anticancer chemotherapy have resulted in an increase in the number of patients requiring a central venous port catheter, and the incidence of catheter pinch-off syndrome has been increasing. Catheter pinch-off syndrome is a rare and unusual complication. It is difficult to retrieve dislodged catheters from the pulmonary artery, especially if the catheter is stuck to the peripheral pulmonary artery. We herein describe the successful removal of a catheter stuck in the pulmonary artery with a stepwise approach. First, a pigtail catheter was used to tug the dislodged catheter in order to free the unilateral end. Then, a gooseneck snare was used to catch and pull the catheter out of the patient. The key to success is to free the end of the catheter. PMID:27668096

    Central venous catheter placement is indicated in many situations, and an increasing number of patients require temporary and long-term central catheters. Frequently, patients who have undergone multiple central veins catheterizations develop complete and diffuse venous occlusion, and this constitutes a difficult-to-manage clinical problem. We report a case of a 20-year-old patient who was referred to our department for central venous line placement who manifested bilateral femoral, jugular, and subclavian veins occlusion. A central venous catheter was implanted through a cervical collateral vein, targeting on and puncturing an angioplasty balloon, and advanced into the collateral vein through a transhepatic venous access.

    As part of the vascular access procedures, venous ports, commonly referred to as catheters, are placed under the skin to enable safe and easy vascular access for administration of repeated drug treatments. 122 patients who had received a venous port catheter insertion procedure in the general surgery department between January 1012 and January 2014 were involved in this study. Patients were divided into two groups: those who had undergone a fluoroscopy (group 1) and those who had not undergone a fluoroscopy (group 2). Complications that emerged during and after the port catheter insertion procedure and successful insertion rates were recorded in the database. Data of these patients were presented in a prospective manner. There were 92 to 30 patients in groups 1 and 2, respectively. In group 1, the mean age was approximately 56.8, total catheter stay time was 20,631 days, and mean time of port use was 224.2 days. In group 2, the mean age was approximately 61.2, total catheter stay time was 13,575 days, and mean time of port use was 452.5 days. Successful insertion rate was 100% and 90% in groups 1 and 2, respectively (P < 0.05). The proper insertion of the port catheter accompanied by monitoring methods can decrease procedure-related complications. Statistical comparisons between the two groups in terms of malposition and successful insertion rates also support this view (P < 0.05). The findings support the view that in cancer patients, a venous port catheter insertion accompanied by a fluoroscopy can be safely performed by general surgeons. PMID:26011202

    A transfemoral venous approach is the current standard for accessing malpositioned and fractured central venous catheters (CVCs). The purpose of this study was (1) to describe a transbrachial approach for correction and (2) to assess the success and failure of this method in a pediatric population. A 12-year retrospective review of all patients referred for correction of malpositioned, retained, and fractured CVCs was conducted. Based on the performing interventionalist's preference, transbrachial or transfemoral venous sheaths where placed under ultrasonographic guidance. Diagnostic angiographic catheters and snares were used to manipulate the catheters. Patients who underwent the transfemoral approach received postprocedural monitoring for 4 hours, whereas patients who underwent the transbrachial approach were allowed unrestricted activity immediately after hemostasis was obtained. Technical success of malpositioned lines was defined (1) by final position in the superior vena cava or at the cavoatrial junction on postprocedural imaging or (2) by successful removal of retained catheter fragments, if present. Transbrachial approach was used for access in 11 patients. Problematic lines included malpositioned (n = 10) and retained (n = 1) lines. The ipsilateral arm was used for transbrachial entry in 7 patients. Initial use of angiographic catheters was attempted in 7 cases, of which 4 were successful. All 3 unsuccessful cases had tips positioned in the contralateral brachiocephalic vein, and these were successfully repositioned using snares. A combination of snares and angiographic catheters was used in 2 cases. Snares were used for all other cases. Technical success by way of the transbrachial approach was observed in all cases. Periprocedural follow-up demonstrated no immediate complications. We conclude that the transbrachial approach is a suitable alternative to the transfemoral approach for catheter tip position correction. Tip malposition in the contralateral

    When planning parenteral nutrition (PN), the proper choice, insertion, and nursing of the venous access are of paramount importance. In hospitalized patients, PN can be delivered through short-term, non-tunneled central venous catheters, through peripherally inserted central catheters (PICC), or - for limited period of time and with limitation in the osmolarity and composition of the solution - through peripheral venous access devices (short cannulas and midline catheters). Home PN usually requires PICCs or - if planned for an extended or unlimited time - long-term venous access devices (tunneled catheters and totally implantable ports). The most appropriate site for central venous access will take into account many factors, including the patient's conditions and the relative risk of infective and non-infective complications associated with each site. Ultrasound-guided venepuncture is strongly recommended for access to all central veins. For parenteral nutrition, the ideal position of the catheter tip is between the lower third of the superior cava vein and the upper third of the right atrium; this should preferably be checked during the procedure. Catheter-related bloodstream infection is an important and still too common complication of parenteral nutrition. The risk of infection can be reduced by adopting cost-effective, evidence-based interventions such as proper education and specific training of the staff, an adequate hand washing policy, proper choices of the type of device and the site of insertion, use of maximal barrier protection during insertion, use of chlorhexidine as antiseptic prior to insertion and for disinfecting the exit site thereafter, appropriate policies for the dressing of the exit site, routine changes of administration sets, and removal of central lines as soon as they are no longer necessary. Most non-infective complications of central venous access devices can also be prevented by appropriate, standardized protocols for line insertion

    Central venous catheters (CVC) are widely used in clinical practice for the administration of chemotherapy, parental nutrition, hemodynamic monitoring, and hemodialysis. International guidelines have defined the right internal jugular vein as the preferred site of CVC insertion and underline that accurate positioning of the catheter tip is essential to maximize the blood flow and reduce long-term complications. Endocavitary electrocardiography (EC-ECG) improves the accuracy of catheter tip positioning without increasing the placement time by the recognition of typical P wave patterns during catheter insertion:the normally shaped P wave identifies the mid to upper superior vena cava, the widest P wave may be used to place the CVC tip at the superior vena cava-right atrium junction, and biphasic P waves identify the location of the right atrium. Because of its simplicity and safety, EC-ECG should always be considered during CVC placement, especially if other means of verifying correct CVC insertion are not available.

    Background A 72 year old male was admitted to the medical intensive care unit with septic shock. Case presentation A left subclavian central venous catheter was inserted on the day of admission whose tip was pushing against the wall of the vessel lumen. The patient's condition improved with treatment, but three days later had a new episode of acute hypotension. CT scan of the chest showed that the catheter had eroded through the superior vena cava wall. Conclusion The catheter was pulled out and patient recovered from the complication with supportive therapy. Care should be taken that the tip of the catheter is in the center of the vessel lumen to avoid this rare, but potentially life threatening, complication. PMID:19036145

    Pigs are used for long-term biomedical experiments requiring repeated injections, infusions and collections of blood samples. Thus, it is necessary for vascular catheters to be indwelling to avoid undue stress to the animals and the use of restraints. We propose a refined model of percutaneous insertion of long-term central venous catheters to minimize the surgical trauma and postoperative complications associated with catheter insertion. Different sizes of needles (18 Ga versus 21 Ga) for initial puncture of the veins were compared. In conventional pigs weighing less than 30 kg, catheter insertion may be facilitated by using a microintroducer set with a 21 Ga needle. In pigs weighing 50 kg, a standard 18 Ga needle may be preferable.

    Pelvic venous embolization is performed for pelvic congestion syndrome and prior to lower limb varicose vein surgery in females with associated pelvic venous insufficiency. The procedure is analogous to varicocele embolization in males, although refluxing internal iliac vein tributaries may also be embolized. We report a case of inadvertent coil placement in the common femoral vein while embolizing the obturator vein, during pelvic vein embolization for recurrent lower limb varicose veins. There were no clinical consequences and the coil was left in situ. We advise caution when embolizing internal iliac vein tributaries where there is clinically significant communication with veins of the lower limb.

A late-preterm newborn, born at 35 weeks of gestational age to a diabetic mother and large for gestational age, with respiratory distress and rule-out sepsis, required an umbilical venous access. After the insertion of the umbilical venous catheter, the patient presented with tachycardia. Chest radiography showed that the catheter was placed in the position that corresponds to the left atrium, and traction was applied. The patient persisted with tachycardia, and an electrocardiogram showed atrial flutter. As the patient was hemodynamically unstable, electric cardioversion was successfully applied. The association between atrial arrhythmias and misplaced umbilical catheters has been described in the literature, but in this case, it is noteworthy that the patient was an infant born to a diabetic mother, which consists in another risk factor for heart arrhythmias. Isolated atrial flutter is a rare tachyarrhythmia in the neonatal period and its identification is essential to establish early treatment and prevent systemic complications and even death.

    Long-term intravenous catheters (LTIVC) are standard practice for patients with chronic diseases such as cancer, digestive disease requiring total parenteral nutrition or end-stage renal disease. Even if they greatly improved patients' care, the use of LTIVC is also associated with microbial contamination and subsequent infection. These catheter-related infections are associated with morbidity, mortality and increased health-care costs. As patients carrying these LTIVC stay at home for their treatment (home parenteral nutrition for instance) or between cycles of treatment (antineoplastic chemotherapy or dialysis), it is mandatory that general practitioner and nurses are aware of recent data on the epidemiology, diagnosis and treatment of LTIVC-related infections.

    Abstract Objective: to evaluate the effectiveness and safety in the use of second-generation central venous catheters impregnated in clorhexidine and silver sulfadiazine when compared with other catheters, being them impregnated or not, in order to prevent the bloodstream infection prevention. Method: systematic review with meta-analysis. Databases searched: MEDLINE, EMBASE, CINAHL, LILACS/SciELO, Cochrane CENTRAL; search in Congress Proceedings and records from Clinical Trials. Results: 1.235 studies were identified, 97 were pre-selected and 4 were included. In catheter-related bloodstream infection, there was no statistical significance between second-generation impregnated catheter compared with the non-impregnated ones, absolute relative risk 1,5% confidence interval 95% (3%-1%), relative risk 0,68 (confidence interval 95%, 0,40-1,15) and number needed to treat 66. In the sensitivity analysis, there was less bloodstream infection in impregnated catheters (relative risk 0,50, confidence interval 95%, 0,26-0,96). Lower colonization, absolute relative risk 9,6% (confidence interval 95%, 10% to 4%), relative risk 0,51 (confidence interval 95% from 0,38-0,85) and number needed to treat 5. Conclusion: the use of second-generation catheters was effective in reducing the catheter colonization and infection when a sensitivity analysis is performed. Future clinical trials are suggested to evaluate sepsis rates, mortality and adverse effects. PMID:27508901

    The totally implantable venous access ports (TIVAPs) are indicated for patients undergoing chemotherapy, total parenteral nutrition and long-term antibiotic treatment. But, among their complications, the fracture and migration of the catheter of a TIVAP via internal jugular vein represents a very rare but potentially severe condition. A 50-year-old woman indentified with a spontaneous fracture and migration of catheter of a TIVAP via right internal jugular vein after adjuvant chemotherapy for ovary cancer. She had been not evaluated and not managed with the heparin lock flush solution during three months after adjuvant chemotherapy. And then, she complained right neck bulging during saline infusion via a TIVAP and a chest radiography showed the fractured and migrated catheter of a TIVAP in right atrium. So, we emergently removed the catheter fragment by a goose neck snare via right femoral vein. After then, there was no problem. If the fractured catheter of a TIVAP is detected, it is desirable to remove a fragment by an endovascular approach if it is possible.

    The aim of this study was to evaluate the technical aspects and efficacy of placing tunneled central venous access catheters (CVA) in the inferior vena cava (IVC) via a direct translumbar approach. Between August 1994 and July 1998, 50 CVA (Hickman 13.5 F) were placed in the IVC via a direct translumbar approach in 46 patients (10 males, 36 females) with a mean age of 39.9 years (age range 10-87 years). The indications were chemotherapy administration plus leukoaphoresis (n = 39), bone marrow transplantation (n = 2) and hemodialysis (n = 5). The reasons for placing the CVA in the IVC were cosmetic (n = 34), supradiaphragmatic venous thrombosis (n = 8), previous catheter infection (n = 2), and non-functioning arteriovenous fistula (n = 2). There were no immediate complications. The mean period of time the CVA was in place was 3 months (15 days to 15 months), during which the function was excellent. The commonest late complication was infection (4 local, 6 bacteremia). Others included: pain (n = 2), ureteric fistula (n = 1), pericatheter fibrin sheath formation (n = 6) and catheter-tip impaction (n = 2). Two catheters were damaged due to postprocedural inappropriate manipulations and two others fell off due to incorrect fixation. Due to these complications, it was necessary to remove ten catheters, replace an additional four and reposition two. Direct translumbar catheterization of the IVC is a safe and effective way of placing a long-term CVA with a moderate complication rate.

    We report a 63-year-old male with central venous catheter-related infection caused by Malassezia sympodialis after total gastrectomy for a gastric cancer. He had fever and his leukocyte counts and C-reactive protein were elevated 14 days after his operation. After his central venous hyperalimentation catheter was removed, the inflammatory signs immediately disappeared, suggesting an intravenous catheter-related infection. A yeast-like fungus was cultured in brain-heart infection semi-solid agar ten days later, and was diagnosed morphologically as Malassezia sp. This strain was identified as M. sympodialis by Tween assimilation test and was confirmed by whole-sequence of internal transcribed spacer 1 regions (ITS1). This is the first report of catheter-related infection caused by M. sympodialis. This strain grew and was subcultured on CHROMagar Candida, potato dextrose agar and Sabouraud agar. There have been no reports of such a lipid-independent Malassezia sp. except for M. pachydermatis. The mechanism of lipid independence of this strain is undetermined and future work is needed. Malassezia sp. is receiving increased attention as an etiologic pathogen of catheter-related fungemia in clinical microbiology laboratories and infectious disease sections.

    This study evaluated the existing technology used to improve the safety and ease of ultrasound-guided central venous catheterization. Electronic database searches were conducted in Scopus, IEEE, Google Patents, and relevant conference databases (SPIE, MICCAI, and IEEE conferences) for related articles on assistive technology for ultrasound-guided central venous catheterization. A total of 89 articles were examined and pointed to several fields that are currently the focus of improvements to ultrasound-guided procedures. These include improving needle visualization, needle guides and localization technology, image processing algorithms to enhance and segment important features within the ultrasound image, robotic assistance using probe-mounted manipulators, and improving procedure ergonomics through in situ projections of important information. Probe-mounted robotic manipulators provide a promising avenue for assistive technology developed for freehand ultrasound-guided percutaneous procedures. However, there is currently a lack of clinical trials to validate the effectiveness of these devices.

    Evaluating thrombi microstructure developed in central venous catheters using confocal and electron microscopy. An experimental, descriptive study carrying out a microstructural evaluation of venous thrombi developed in central venous catheters using Scanning Electron Microscopy and Confocal Laser Scanning Microscopy. A total of 78 venous catheters were collected over a period of three months. Different fibrin structures were distinguished: fibrin plates, fibrin network, and fibrin fibers. It was observed that the thrombus had thick fibrin plates adhered to the catheter wall openings in both a catheter with three days of permanence as well as in a catheter with 20 days of insertion in the patient. However, a greater amount of erythrocytes and fibrin fibers were found in the central region of the thrombus. This study contributes to improving health care and can have a positive impact on clinical practice, as easy adherence of platelets and fibrins to the catheter wall demonstrated in this study makes it possible to adopt thrombus prevention strategies such as therapy discontinuation for an extended period, blood reflux by a catheter, slow infusion rate and hypercoagulo pathyclinical conditions.

    Umbilical venous catheterization has become a widely accepted intravenous route for premature babies. These catheters allow administration of parenteral nutrition and medication and facilitate blood sampling. Besides these benefits, they also have significant potential complications like portal vein thrombosis, infection, vascular or hepatic injury, arrhythmia and sepsis. One of the rare but important complication is extravasation of the fluids due to misplacement of the catheter. The typical symptoms of this condition are sudden deterioration, hepatic enlargement, hematocrit drop, hypotension and abdominal distension. We herein present a premature newborn with unusual acute abdomen findings suggesting a surgical pathology after the extravasation of total parenteral nutrition into the abdomen.

    Multiple sclerosis (MS) is a disorder characterized by damage to the myelin sheath insulation of nerve cells of the brain and spinal cord affecting nerve impulses which can lead to numerous physical and cognitive disabilities. The disease, which affects over 500,000 people in the United States alone, is widely believed to be an autoimmune condition potentially triggered by an antecedant event such as a viral infection, environmental factors, a genetic defect or a combination of each. Chronic cerebrospinal venous insufficiency (CCSVI) is a condition characterized by abnormal venous drainage from the central nervous system that has been theorized to have a possible role in the pathogenesis and symptomatology of MS (1). A significant amount of attention has been given to this theory as a possible explanation for the etiology of symptoms related to MS patients suffering from this disease. The work of Dr. Zamboni, et al, who reported that treating the venous stenoses causing CCSVI with angioplasty resulting in significant improvement in the symptoms and quality of life of patients with MS (2) has led to further interest in this theory and potential treatment. The article presented describes endovascular techniques employed to diagnose and treat patients with MS and CCSVI.

    We report the results of a 4-years-experience with Hickman-Broviac double lumen silicone catheters. The catheters were inserted in 51 dialysed and nondialysed children. Forty three catheters were placed for temporary or permanent dialysis access, 2 in patients for plasmapheresis, 4 in severely burnt patients, and 2 in neonates with the "short gut" syndrome. The youngest patient was 7 days old and the eldest 14.5 years (mean age 5.4 years). The catheters were implanted by open surgery into the right atrium through the right (92%) or left internal jugular vein (8%) in more than 80% of patients. Ten catheters were implanted in the femoral vein (three through the saphenous vein: in a patient with extensive burns in the thorax and neck area, and in seven patients with acute renal failure and high risk for anaesthesia). The complications, except the insufficient flow, were fewer and less dangerous than those reported in literature. Therefore, we strongly recommend insertion of these catheters as the method of choice for immediate vascular access in children in whom the creation of conventional vascular access is difficult or impossible, as well as in patients in whom provision of long- term intravenous nutrition or medication is essential.

    Background and Aim The use of venous catheters is a widespread practice, especially in oncological and oncohematological units. The objective of this study was to evaluate the complications associated with peripherally inserted central catheters (PICCs) in a cohort of patients. Materials and Methods In this retrospective cohort study, we included all patient carrying PICCs (n = 603) inserted at our institute between October 2010 and December 2013. The main variables collected were medical diagnosis, catheter care, location, duration of catheterization, reasons for catheter removal, complications, and nursing care. Complications were classified as infection, thrombosis, phlebitis, migration, edema, and/or ecchymosis. Results All patients were treated according to the same “nursing care” protocol. The incidence rate of complications was two cases per 1000 days of catheter duration. The most relevant complications were infection and thrombosis, both with an incidence of 0.17 cases per 1000 days of the total catheterization period. The total average duration of catheterization was 170 days [SD 6.06]. Additionally to “end of treatment” (48.42%) and “exitus”, (22.53%) the most frequent cause of removal was migration (displacement towards the exterior) of the catheter (5.80%). Conclusions PICCs are safe devices that allow the administration of long-term treatment and preserve the integrity of the venous system of the patient. Proper care of the catheter is very important to improve the quality life of patients with oncologic and hematologic conditions. Therefore, correct training of professionals and patients as well as following the latest scientific recommendations are particularly relevant. PMID:27588946

    Six hundred and fifty-five central venous catheters (CVC) in 496 patients in the intensive care unit of Hospital Sultanah Aminah were studied to determine the incidence and risk factors for central venous catheter-related blood stream infection (CR-BSI). CR-BSI was diagnosed in 38 catheters, giving an incidence of 9.43 CR-BSI per 1000 catheter days. The mean duration in situ was 8.4 +/- 4.9 days for infected CVCs and 6.0 +/- 3.8 days for non infected CVCs (p = 0.001). CVCs inserted in ICU had the highest infection rate (9.4%) compared to those inserted in the operating theatre (1.4%) and ward (2.8%) (p = 0.001). The highest rate of CR-BSI occurred with 4-lumen catheters (usually inserted when patients needed total parenteral nutrition) with a percentage of 15.8%. The majority of the CVCs (97.9%) were inserted via the subclavian or the internal jugular routes and there was no statistical difference in CR-BSI between them (p = 0.83). Number of attempts more than one had a higher rate of CR-BSI compared to single attempt with percentage of 7.0% vs 4.8% (p = 0.22). The top two organisms were Klebseilla pneumoniae and Pseudomonas aeruginosa. In conclusion, the incidence of CR-BSI in our ICU was 9.43 CR-BSI per 1000 catheter days. The risk factors were duration of CVC in situ, venue of insertion and use of 4 lumen catheter for total parenteral nutrition. The site of insertion, number of lumen up to 3 lumens and the number of attempts were not risk factors.

    The frequency and risk factors for central venous catheter-related thrombosis (CRT) during prolonged intravenous (i.v.) antibiotic therapy have rarely been reported. The primary objective of this study was to evaluate the frequency, incidence, and risk factors for CRT among patients being treated with prolonged i.v. antibiotic therapy. The secondary objective was to describe the clinical manifestations, diagnostic evaluation, and clinical management. This cohort study was conducted between August 2004 and May 2010 in a French referral center for osteoarticular infections. All patients treated for bone and joint infections with i.v. antimicrobial therapy through a central venous catheter (CVC) for ≥2 weeks were included. Risk factors were identified using nonparametric tests and logistic regression. A case-control study investigated the role of vancomycin and catheter malposition. A total of 892 patients matched the inclusion criteria. CRT developed in 16 infections occurring in 16 patients (incidence, 0.39/1,000 catheter days). The median time to a CRT was 29 days (range, 12 to 48 days). Local clinical signs, fever, and secondary complications of CRT were present in 15, 8, and 4 patients, respectively. The median C-reactive protein level was 95 mg/liter. The treatment combined catheter removal and a median of 3 months (1.5 to 6 months) of anticoagulation therapy. The outcome was good in all patients, with no recurrence of CRT. Three risk factors were identified by multivariate analysis: male sex (odds ratio [OR], 5.4; 95% confidence interval [CI], 1.1 to 26.6), catheter malposition (OR, 5.3; 95% CI, 1.6 to 17.9), and use of vancomycin (OR, 22.9; 95% CI, 2.8 to 188). Catheter-related thrombosis is a rare but severe complication in patients treated with prolonged antimicrobial therapy. Vancomycin use was the most important risk factor identified.

    Vascular access is invaluable in the treatment of hospitalized patients. Central venous catheters provide a durable and long-term solution while saving patients from repeated needle sticks for peripheral IVs and blood draws. The initial catheter placement procedure and long-term catheter usage place patients at risk for infection. The goal of this project was to develop a system to track and evaluate central line-associated blood stream infections related to interventional radiology placement of central venous catheters. A customized web-based clinical database was developed via open-source tools to provide a dashboard for data mining and analysis of the catheter placement and infection information. Preliminary results were gathered over a 4-month period confirming the utility of the system. The tools and methodology employed to develop the vascular access tracking system could be easily tailored to other clinical scenarios to assist in quality control and improvement programs.

    An adequate vascular access is of importance for the treatment of patients with cancer and complex illnesses in the intensive, perioperative or palliative care setting. Deep vein thrombosis and thrombotic occlusion are the most common complications attributed to central venous catheters in short-term and, especially, in long-term use. In this review we will focus on the risk factors, management and prevention strategies of catheter-related thrombosis and occlusion. Due to the lack of randomised controlled trials, there is still controversy about the optimal treatment of catheter-related thrombotic complications, and therapy has been widely adopted using the evidence concerning lower extremity deep vein thrombosis. Given the increasing use of central venous catheters in patients that require long-term intravenous therapy, the problem of upper extremity deep venous thrombosis can be expected to increase in the future. We provide data for establishing a more uniform strategy for preventing, diagnosing and treating catheter-related thrombotic complications.

    ABSTRACT Introduction: Central Venous Catheters (CVC) are essential in everyday medical practice, especially in treating patients in intensive care units (ICU). The application of these catheters is accompanied with the risk of complications, such as the complications caused during the CVC insertion, infections at the location of the insertion, and complications during the use of the catheter, sepsis and other metastatic infections. Patients and methods: This study is a retrospective-prospective and it was implemented in the period 1st January 2011- 31st December 2012. It included 108 examinees with CVC placed for more than 7 days. Results: The most common complications occurring in more than 2 attempts of CVC applications are: hearth arrhythmias in both groups in 12 cases, 7 in multi-lumen (12.72%) and 5 in mono-lumen ones (9.43%). Artery puncture occurs in both groups in 7 cases, 5 in multi-lumen (9.09%) and 2 in mono-lumen ones (3.77%). Hematoma occurred in both groups in 4 cases, 3 in multi-lumen CVCs (5.45%) and 1 in mono-lumen ones (1.88%). The most common complication in multi-lumen catheters was heart arrhythmia, in 20 cases (36.37%). The most common complications in mono-lumen CVCs was hearth arrhythmias, in 20 cases as extrasystoles and they were registered in 16 catheter insertions (30.18%). Out of total number of catheters of both groups, out of 108 catheters the complications during insertion occurred in 49 catheters (45.40%). The most common complications in both groups were heart arrhythmias, artery punctures and hematomas at the place of catheter insertion. PMID:25568558

    Introduction Intramuscular venous malformations have been previously described as intramuscular hemangiomas, and various therapies have been applied for their treatment. This condition is relatively rare, and therefore, physicians often struggle to determine the appropriate therapy. We presented a case of an enlarged intramuscular venous malformation relapsed after surgery successfully treated with complete resection. Presentation of case We presented a case of an enlarged intramuscular venous malformation with postoperative recurrence successfully treated with complete resection. A 63-year-old woman presented with a subcutaneous mass in the right distal thigh. She experienced swelling in the right thigh 19 years previously and was diagnosed with a venous aneurysm. Three-dimensional CT angiography confirmed the presence of an irregular vessel assumed to be the feeding vessel, which was dendritically branched from the deep femoral artery. We performed surgical complete resection. Her pain and gait disturbance improved after surgery, and she has not experienced recurrence of the mass for the past 2 years. Discussion Conservative therapy is initially used for venous malformations. Sclerotherapy, laser therapy, or surgical resection is considered after low-dose aspirin therapy, in combination with the use of compressive garments. Surgical resection is indicated for completely resectable lesions and is appropriate for large lesions in terms of cosmetic benefit. However, partial resection may result in excessive bleeding or postoperative recurrence. Conclusion The therapy for venous malformations should be decided based on the degree of disability in daily living, adjacent tissue damage, and cosmetic concerns after appropriate differential diagnostic investigations and biopsy.

    In this prospective, observational study, we sought to investigate the incidence, risk factors, and outcomes of central venous catheter-associated infection in 56 patients admitted for hematopoietic stem cell transplantation. In multivariate analysis, we found a 7-fold higher risk of central line-associated bloodstream infection with central venous catheter insertion in the internal jugular vein as compared with the subclavian access. Patients with central line-associated bloodstream infection had a higher incidence of acute renal failure.

    Objective: to develop and validate an educational digital video on changing the dressing of short-term, non-cuffed, non-tunneled central venous catheters in hospitalized adult patients. Method: this is a descriptive, methodological study based on Paulo Freire's assumptions. The development of the script and video storyboard were based on scientific evidence, on the researchers' experience, and that of nurse experts, as well as on a virtual learning environment. Results: the items related to the script were approved by 97.2% of the nurses and the video was approved by 96.1%. Conclusion: the educational instrument was considered to be appropriate and we believe it will contribute to professional training in the nursing field, the updating of human resources, focusing on the educational process, including distance education. We believe it will consequently improve the quality of care provided to patients with central venous catheters. PMID:26626011

    Keeping the operating field clean and visible is an important technique in neurosurgery. Continuous irrigation-suction (IS) of the surgical field is currently often done using devices available that are expensive and demand technical proficiency. We report a simple method of continuous IS using a widely available central venous catheter and a controlled suction cannula. We used a controlled suction cannula attached to a central suction system. A single lumen central venous catheter is passed through the keyhole of a controlled suction cannula, which is connected to a continuous irrigation system. The operative field was clean throughout the procedure, obviating the need for an assisting surgeon to irrigate into the deep operating field and, hence, reducing the duration of surgery. The proposed IS system could be surgeon friendly, easily manageable, yet cost-effective and efficient. Copyright © 2016 Elsevier Inc. All rights reserved.

    Central venous stenosis (CVS) in hemodialysis patients could be secondary to central venous catheterization, high flow arteriovenous fistula, as well as extrinsic compression. However, we report a senile hemodialysis patient of left internal jugular vein stenosis and right innominate vein occlusion unrelated to any known risk factors. Aided by computed tomography and digital subtraction angiography, we managed to dilate the stenosis by percutaneous balloon angioplasty, followed by successful tunneled catheter placement. Nephrologists should be aware of idiopathic CVS and its impact on the creation and preservation of vascular access. When confronted with difficulties in catheter placement, practitioners need to consider the possibilities of idiopathic CVS and refer to radiological tests. © 2013 International Society for Hemodialysis.

    Malfunctioning tunneled hemodialysis central venous catheters (CVCs), because of thrombotic or infectious complications, are frequently exchanged. During the CVC exchanging procedure, there are several possible technical complications, as in first insertion, including air embolism. Prevention remains the key to the management of air embolism. Herein, we emphasize the technical tricks capable of reducing the risk of air embolism in long-term CVC exchange. In particular, adoption of a 5 to 10 degrees Trendelenburg position, direct puncture of the previous CVC venous lumen for guide-wire insertion, as opposed to guide-wire introduction after cutting the CVC, a light manual compression of the internal jugular vein venotomy site after catheter removal. The Valsalva maneuvre in collaborating patients, valved introducers, and correction of hypovolemia are also useful precautions. Principles of air embolism diagnosis and treatment are also outlined in the article.

    For successful catheter placement, central venous cannulation (CVC) through internal jugular vein and subclavian vein has been recommended in both adult and pediatric patients. But it carries a risk of serious complications, such as pneumothorax, carotid, or subclavian artery puncture, which can be life-threatening, particularly in critically ill children. So a prospective study was carried out to determine the success rate of correct catheter tip placement during CVC through antecubital veins in pediatric neurosurgical patients. A total of 200 pediatric patients (age 1-15 years) of either sex were studied. Basilic or cephalic veins of either arm were selected. All the patients were cannulated in the operation room under general anesthesia. Single lumen, proper size catheters (with stillete) were used for cannulation. The catheter was inserted in supine position with the arm abducted at right angle to the body and neck turned ipsilaterally. The length of insertion was determined from cubital fossa to the right second intercostal space. The exact position of the tip of the catheter was confirmed radiologically in ICU. Correct catheter tip placement was achieved in 98 (49%) patients. Multivariate logistic regression analysis of data shows that there was no statistically significant difference among correct and incorrect catheter tip placement in relation to factors including sex, side of cannulation (left or right), and type of vein (basilic or cephalic). The analysis of correct catheter tip placement in relation to age showed that the highest success rate was achieved in children of age group 6 to 10 years (60.2%) followed by 30.6% in the 11 to 15 year group. The lowest success rate of tip placement of only 9.2% was observed in younger children of age 1 to 5 years, which is statistically significant (P = 0.001). Of 102 incorrect placements reported, 37% were in 1 to 5 year age group versus 9.2% correct tip placements. The most common unsatisfactory placements were

    Thirty-one critically ill patients with acute respiratory failure and circulatory shock were divided into three groups. Group 1 included 11 patients with an inserted mixed venous saturation (SvO2) catheter using three-reference wavelengths and characterized by one transmitting and one detecting fiberoptic filament (Oximetrix opticath catheter); group 2 included eight patients with an inserted SvO2 catheter using two-reference wavelengths and characterized by one transmitting and one detecting fiberoptic filament; (Edwards sat-one catheter); group 3 included 12 patients with an inserted SvO2 catheter using two-reference wavelengths and characterized by one transmitting and two detecting fiberoptic filaments. Once calibration procedures were performed, SvO2 measured by the catheter and by an hemoximeter OSM 3 (reference value) were compared following each therapeutic intervention. Over a period of 1.5 to 6 hours during which the hematocrit value remained unchanged, 119 measurements were obtained in group 1, 91 in group 2 and 181 in group 3. The dispersion of SvO2 values was much more pronounced with the two-reference wavelength systems using either one or two detecting fiber optic filaments, and the correlation coefficient was significantly higher with the three-reference wavelength system (r = 0.970 for the Oximetrix catheter vs r = 0.855 for the Edwards catheter and r = 0.826 for the Spectramed catheter, p less than 0.001). After 24 hours, the spontaneous drifts in the two-reference wavelength systems, using either one or two detecting fiber optic filaments (expressed as the SvO2 value measured by the catheter minus the reference SvO2 value) were significantly higher than the spontaneous drift in the three-reference wavelength system (9.3 +/- 7 percent for the Edwards catheter and +/- 6 +/- 4.1 percent for the Spectramed catheter vs 3.3 +/- 3.1 percent for the Oximetrix catheter, p less than 0.05). This study shows that a three-wavelength system is more accurate

    To determine the effect of routine intravenous (IV) administration set changes on central venous catheter (CVC) colonization and catheter-related bacteremia. Prospective, randomized, controlled trial. Eighteen-bed intensive care unit (ICU) in a large metropolitan hospital. Two hundred fifty-one patients with 404 chlorhexidine gluconate and silver sulfadiazine-coated multi-lumen CVCs. CVCs inserted in the ICU and in situ on day 4 were randomized to have their IV administration sets changed on day 4 (n = 203) or not at all (n = 201). Use of fluid containers and blood product administration sets was limited to 24 hours. CVCs were removed when not required, infection was suspected, or in place on day 7. Catheter cultures were performed on removal by blinded laboratory staff. Catheter-related bacteremia was diagnosed by a blinded intensivist using strict definitions. Data were collected regarding catheter duration, site, Acute Physiology and Chronic Health Evaluation (APACHE) II score, patient age, diagnosis, hyperglycemia, hypoalbuminemia, immune status, number of fluid containers and IV injections, and administration of propofol, blood, total parenteral nutrition, or lipid infusion. There were 10 colonized CVCs in the group receiving a set change and 19 in the group not receiving one. This difference was not statistically significant on Kaplan-Meier survival analysis. There were 3 cases of catheter-related bacteremia per group. Logistic regression found that burns diagnosis and increased ICU stay significantly predicted colonization. IV administration sets can be used for 7 days in patients with short-term, antiseptic-coated CVCs.

    Central venous catheter (CVC) placement is associated with increased risk of thrombosis in the paediatric population, particularly in relation to the type of catheter and the manner of its insertion. Here, we investigate risk factors associated with CVC-related thrombosis in children, with particular emphasis on positioning of the catheter tip. Patients aged 0-18 who underwent at least one CVC placement from 2008 to 2013 at a single centre with a subsequent follow-up echocardiogram were included for a total of 104 patients and 147 lines. Data on clinical and catheter-related risk factors were collected from patient charts. Statistical analysis using Pearson's χ tests, independent samples t-test, and odds ratios were used to assess potential risk factors for thrombosis. Neither insertion site (subclavian vein or otherwise), left- vs. right-sided insertion, nor catheter type were significant risk factors for thrombosis. There were no thrombotic events reported at the superior vena cava (SVC)-right atrium junction and no significant differences in thrombotic risk with initial tip placement in the SVC-right atrium junction vs. the SVC, right atrium, or inferior vena cava. Acute lymphoblastic leukaemia was a major clinical risk factor for thrombosis. Tip movement was common and may have been an important factor in the development of CVC-related thrombi. Prospective studies can yield insight into the role of follow-up imaging in the prevention of catheter-related thrombosis in children.

    We report a case of puncture of the thoracic duct during left subclavian vein catheterization on the intensive care unit. Computed tomography and measurement of the triglyceride levels in the aspirated fluid proved the inadvertent penetration of the guidewire into the thoracic duct. Early recognition of central line misplacement avoided serious complications. Inadvertent central venous catheter placement into the thoracic duct may have the potential complications of infusion mediastinum and chylothorax.

    Indwelling central venous catheters (CVCs) are used in the management of hematologic patients. However, insertion and maintenance of CVCs are susceptible to complications. Study design and methods data concerning 388 consecutive catheterisations, performed in oncohematologic patients between April 2003 and December 2004, were prospectively collected. At insertion thrombocytopenia was present in 109 cases (28.1%) and neutropenia in 67 (17.3%). Hemorrhage after CVC insertion occurred in five thrombocytopenic patients (1.3%). The median duration of catheterisation was 18.8 days (range 1-89), longer in the 7-French CVCs utilised in leukemic patients (24.3 days) and shorter in 12-French CVCs (11 days), used for PBSC harvesting. Deep venous thrombosis was diagnosed in 13 cases (3.3%). Ninety-two catheterisations (12.6/1000 days-catheter) were complicated by infections: 19 local infections (4.8%) and 73 (18.8%) bacteraemias of which 45 (11.6%) were catheter-related, mainly due to Gram positive germs (32/45, 71.1%). The frequency of catheter-related bacteraemia was 7.2 events/1000 days-catheter. Thirteen CVCs were removed due to thrombosis, 15 due to infections, 20 due to malfunction, the remaining 333 at patients discharge. At univariate analysis high-dose chemotherapy (p = 0.013), 7-Fr lumen (p = 0.023), acute myeloid leukemia (AML) (p = 0.001), duration of neutropenia >10 days and length of catheterisation were significantly correlated to infection. Multivariate analysis confirmed the duration of catheterisation, AML and high-dose chemotherapy as risk factors. Even though hematological in-patients are at increased risk for bleeding and infections, non-tunnelled CVCs offer a safe venous access also in patients affected by severe thrombocytopenia and prolonged neutropenia.

    Functional outcome of venous stent placement for the management of acute iliofemoral deep vein thrombosis (DVT) following catheter-directed thrombolysis (CDT), remain undefined. The purpose of this study was to assess immediate and intermediate term outcomes among patients treated with venous stenting following CDT in patients with proximal lower limb DVT. Thirty consecutive patients aged between 20-70 years with proximal lower limb DVT formed the study group. The mean duration of CDT done with streptokinase was 4.5 ± 1.3 days. Patients with residual venous obstruction and/or large clot burden were treated further with venous angioplasty and/or stenting. Primary endpoint was to evaluate the safety, efficacy and patency of venous stenting in the management of incomplete result following CDT. After 12 months, post-thrombotic syndrome (PTS) was assessed clinically using Villalta scale and deep venous patency was assessed through duplex ultrasound. We studied 8 (5 female and 3 male) patients with 9 (3 left and 6 right) limb involvement and 13 stent (4 balloon expandable and 9 self expandable) placement. All patients improved clinically immediately following venous stenting. Technical success was achieved in all patients. One patient developed pulmonary embolism during course of hospital stay. One patient had stent thrombosis and PTS and another patient died due to carcinoma breast during follow-up. Deep venous stenting is an effective mode of treatment in proximal acute lower limb DVT with high late patency rate up to 1-year.

    BACKGROUND: The current standard for confirmation of correct supra-diaphragmatic central venous catheter (CVC) placement is with plain film chest radiography (CXR). We hypothesized that a simple point-of-care ultrasound (POCUS) protocol could effectively confirm placement and reduce time to confirmation. METHODS: We prospectively enrolled a convenience sample of patients in the emergency department and intensive care unit who required CVC placement. Correct positioning was considered if turbulent flow was visualized in the right atrium on sub-xiphoid, parasternal or apical cardiac ultrasound after injecting 5 cc of sterile, non-agitated, normal saline through the CVC. RESULTS: Seventy-eight patients were enrolled. POCUS had a sensitivity of 86.8% (95%CI 77.1%–93.5%) and specificity of 100% (95%CI 15.8%–100.0%) for identifying correct central venous catheter placement. Median POCUS and CXR completion were 16 minutes (IQR 10–29) and 32 minutes (IQR 19–45), respectively. CONCLUSION: Ultrasound may be an effective tool to confirm central venous catheter placement in instances where there is a delay in obtaining a confirmatory CXR. PMID:28123616

    There is an increasing incidence of infective endocarditis secondary to central venous catheters, which is termed as 'healthcare-associated infective endocarditis'. There is an increased risk of getting infective endocarditis in conditions with malnutrition and also if the tip of the central venous catheter is deep in the right atrium close to the tricuspid valve. We present a case of 31-year-old female who had all these risk factors. She was admitted to the hospital for the work up of the weight loss and was diagnosed with celiac disease. Central venous access was obtained because of poor peripheral intravenous access via the peripherally inserted central catheter which was complicated by thrombosis and removed after three days of insertion, and she was started on anticoagulation. Two weeks after being discharged, she presented to the emergency department with fever, shortness of breath, and had signs of congestive heart failure. A computed tomography of the chest for pulmonary embolism was taken and showed small clot burden pulmonary embolism and two cavitary lesions in the right lung. A transthoracic echocardiogram was taken and showed vegetation on the tricuspid valve and blood cultures were positive for Staphylococcus aureus. Hence, a diagnosis of infective endocarditis was made, and she was treated with intravenous antibiotics for a total of six weeks after a long and complicated hospital stay. PMID:28348945

    Clotting is a serious problem in patients with A-V shunts. Balloon Embolectomy catheters or irrigating devices are frequently unsuccessful in declotting shunts, resulting in surgical revision of the shunt. Frequent surgical revisions reduce sites of vascular access, making it difficult to perform adequate hemodialysis. New instruments, constructed mainly of stainless steel, have been devised and used to declot A-V shunts. The instruments have been devised for specific purposes and labeled as follows: (1) Explanding Mesh, (2) Helix and (3) Rotating Cutter. These instruments will dislodge and remove organized clots, snare and cut fibrin "flaps", open and enlarge the vessel lumens. They have been used successfully in removing vascular obstructions adjacent to the vessel tips of the shunt or at the site of anastamosis of the shunt and vessel. These are the most common sites of obstruction. By prolonging shunt life we have been able to decrease the number of shunt revisions.

    The purpose of this study is to describe a novel method to visualize the position of central venous catheters, which is safe, expeditious, and less expensive than the routine postprocedural chest radiograph. Retrospective comparative study. Dialysis Center of the Department of Nephrology, Klinikum rechts der Isar, Technische Universität München, Munich, Germany. Two hundred and two adult patients undergoing central venous catheter placement for dialysis, plasmapheresis, or administration of medication and solutions. None. Data of 202 adult patients with 219 central venous catheterizations were retrospectively analyzed. Each catheter insertion was followed by an agitated saline bubble-enhanced transthoracic echocardiography, which was used to localize the tip of the catheter. The position of catheter was then controlled by chest radiograph in all cases. During the 13-month study period, two catheter malpositions occurred. Both were identified by agitated saline bubble-enhanced transthoracic echocardiography and confirmed by chest radiograph. The mean time between catheter insertion and chest radiograph control (28.3 min) was clearly longer than agitated saline bubble-enhanced transthoracic echocardiography (3.2 min) (p < 0.001). The total costs of the procedure were reduced by 86.7-95.0%. Specific complications related to the procedure were not observed. The results revealed that the accuracy of agitated saline bubble-enhanced transthoracic echocardiography is equivalent to the chest radiograph. It offers a safe, cost-effective, expeditious alternative to routine chest radiograph for position controls of central venous catheters.

    The use ofa central venous(CV)port system has become common for the treatment of patients with tumors. We report on the failure to remove CV catheters in 2 patients. The first patient was a 50 years woman with acute myeloid leukemia. She underwent CV port implantation via the left brachial approach 11 years previously. The second patient was an 80 years man with a lower gingival carcinoma. He underwent CV port implantation via the left brachial approach 6 years previously. CV catheter removal was attempted in both patients, but was unsuccessful because of strong adhesion to the vessel wall. Based on our experience, if catheter removal is impossible, its retention is more suitable.

    Kocuria kristinae is a catalase-positive, coagulase-negative, Gram-positive coccus found in the environment and in normal skin and mucosa in humans; however, it is rarely isolated from clinical specimens and is considered a nonpathogenic bacterium. We describe a case of catheter-related bacteremia due to K. kristinae in a young adult with propionic acidemia undergoing periodic hemodialysis. The patient had a central venous catheter implanted for total parenteral nutrition approximately 6 months prior to the onset of symptoms because of repeated acute pancreatitis. K. kristinae was isolated from two sets of blood cultures collected from the catheter. Vancomycin followed by cefazolin for 16 days and 5-day ethanol lock therapy successfully eradicated the K. kristinae bacteremia. Although human infections with this organism appear to be rare and are sometimes considered to result from contamination, physicians should not underestimate its significance when it is isolated in clinical specimens.

    Sixty central venous catheterizations in 53 patients were prospectively studied with respect to phlebographic findings after prolonged parenteral nutrition. Phlebography was performed by a special technique on completion of the intravenous therapy. Under fluoroscopic control, the central venous catheter was slowly removed, while simultaneously contrast medium was continuously injected through it. Two types of thrombosis were demonstrated--sleeve thrombosis, on 25 occasions (42%), and mural veno-occlusive thrombosis, on five occasions (8%). On removal of the catheter the sleeve thrombosis peeled off the catheter and in several cases it was noticed that parts of the sleeve thrombus or the entire sleeve became detached and were carried away with the blood flow. Although the sleeve thrombus seldom gave rise to any symptoms, this type of thrombosis is of great importance in view of the risk of pulmonary embolism, especially in connection with removal of the catheter. With use of the described phlebographic technique thrombi of this type can be visualized. Images Fig. 1A. Fig. 1B. Fig. 2. Fig. 3. Fig. 4. PMID:7305496

    The tip of a central vein catheter for hemodialysis should be located in the upper right atrium for the best performance. Hemodialysis catheters do have internal diameter unadjusted to the catheter length; however, the longer the catheter the slower the flow at the same pressure difference. On the other hand, the catheter diameter cannot be so large as to fill the vein too tightly as it predisposes to the damage of the vein wall, thrombosis and stenosis. Therefore, the catheter length and diameter should be appropriate for the patient. For this purpose, the exact dimensions of the venous system in vivo should be known. In this study we correlated the anthropometric measurements and the dimensions of the large upper body veins in 31 adult volunteers. After deep inspiration, magnetic resonance imaging of the chest was performed in three planes; the positions of specific points in the three-dimensional coordinate system were measured, and the distance to adjacent points was calculated according to the analytic geometry formula. The total length from the catheter entry point to the right atrium was the sum of distances between the adjacent points. The lengths of the veins were correlated with the body anthropometric measurements (height, weight, body surface area, bi-acromion span, and height plus bi-acromion span). The best overall correlations of the lengths and diameters of the large upper body veins are with the body surface area. A table is included to guide the selection of the total catheter length and diameter in relation to the body surface area and insertion site.

    Objective Although use of the peripherally inserted central venous catheter (PICC) has become increasingly common, there are few reports of PICCs used for patients with hematologic diseases. In this study, we analyzed the safety of PICC placement in patients with hematologic diseases where PICCs had been placed to perform blood collection, blood transfusion, drug administration, and hematopoietic stem cell transplantation. Methods This study included 142 PICCs placed in 95 patients managed at our department from November 2013 to December 2015. The PICCs used were the GroshongⓇ Catheter (NXT single-lumen; BARD Inc.). Results A total of 95 patients underwent the placement of 142 PICCs. The mean patient age was 65.5 years. The total duration of catheterization was 8,089 days, with a mean duration of 57.0 days. Chemotherapy was administered through 107 catheters. Stem cells were injected through 12 catheters. Although a fever was observed in association with 103 catheters, it was generally controlled by antimicrobial therapy. There were 18 catheter-related bloodstream infection (CRBSI) cases, an incidence equivalent to 2.1 cases per 1,000 catheter-days. Conclusion The present study demonstrated a low CRBSI incidence rate and found no evidence of serious complications with PICC placement. PICCs can be used for blood collection, blood transfusion, drug administration, and hematopoietic stem cell transplantation without problems. Thus, PICC placement appears to be a safe procedure for patients with hematologic diseases. Safe catheters are therefore urgently needed for these patients. We expect that PICCs will be widely adopted in Japan in the near future. PMID:28202859

    Antimicrobial- and antiseptic-impregnated catheters are strategies recommended to prevent central venous catheter (CVC) colonisation. Few data regarding chlorhexidine/silver sulfadiazine-impregnated catheters in intensive care unit (ICU) patients have been reported. We performed a prospective, randomised study comparing the colonisation rates of chlorhexidine/silver sulfadiazine-impregnated CVCs (group 1) against standard CVCs (group 2). In order to assess catheter colonisation rates, a 4cm segment from the tips of aseptically removed catheters was cultured by the roll-plate method. In all, 109 patients were enrolled with successful catheter insertion, 51 of them in group 1 and 58 in group 2. There were no statistically significant differences between the two groups with regards to age, Sequential Organ Failure Assessment (SOFA) score, ICU admission diagnosis, infection risk, catheter insertion sites or catheter length of stay. The colonisation rates were 29.4% (15 catheters) for group 1 and 34.5% (20 catheters) for group 2 (P=0.50). Double-lumen CVCs impregnated with chlorhexidine and silver sulfadiazine were not effective in reducing the incidence of catheter colonisation in ICU patients.

    We report a case of a patient with septic shock who underwent central venous catheter placement in the left internal jugular vein, and a bedside ultrasound 'bubble study' revealed venous cannulation. A chest X-ray postprocedure revealed concern for arterial system catheterisation. However, the possibility of a persistent left superior vena cava was discussed and confirmed with a formal transthoracic echocardiogram and CT. This case demonstrates the importance of ultrasound-guided visualisation of anatomical structures in real time during central venous catheterisation. Other similar cases from the literature are briefly described. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    Does the electrocardiographic method for central venous catheter positioning distinguish between a correct intravasal and a malpositioned extravasal position? 24 cardiac surgical patients were enrolled in this prospective observational study. In 18 patients the left, in another 6 patients the right internal jugular vein was cannulated. Using a J-wire within a triple-lumen catheter the amplitude of the P-wave was measured at 3 different intravasal sites: Intra-1: (intravasal baseline electrocardiogram), i. e. 10 cm marking of the catheter on skin level; Intra-2: clear rise of the P-wave amplitude upon further insertion of the catheter; Intra-3: maximum P-wave amplitude. At this position the control of the catheter tip was achieved by means of transoesophageal echocardiography (TOE). Intraoperatively, another J-wire within a triple-lumen catheter was placed by the heart surgeon on 3 extravasal sites and the ECG was recorded: Extra-1: extravasal at the left innominate vein above the pericardial reflection; Extra-2: extravasal on the superior vena cava below the pericardial reflection; Extra-A: extravasal on ascending aorta below the pericardial reflection. The catheter was suture fixed with its tip in position Intra-3. Post surgery a chest radiograph was taken. All catheter tips were visualised at the basis of the Crista terminals (border between right atrium and superior vena cava) by TOE control. The rise of the P wave amplitude at Intra-2, Extra-2 and Extra-A was highly significant compared to the base line at Intra-1 (Intra-1/Intra-2, Intra-1/Extra-2, Intra-1/Extra-A: p in each case < 0.001). The P wave amplitudes of the corresponding intra- and extravasal positions of the left innominate vein (Intra-1/Extra-1, n = 18, p = 0.096)) as well as those of the superior vena cava (Intra-2/Extra-2, n = 24, p = 0.859) did not differ. The electrocardiographic method can not differentiate between intra- and extravasal position of a central venous catheter, and thus

    A prospective study of 45 central venous catheters was conducted to assess, by strain delineation, the turnover of skin and catheter hub (superficial) colonization and the relative contributions of catheter hub and skin colonization to catheter tip colonization. Serial quantitative cultures of skin and catheter hub were performed. Catheter tip, blood, and specimens for culture from targeted superficial sites (TSSs) were also collected at the time of catheter removal. Strains from 17 tip-positive catheters were delineated by pulsed-field gel electrophoresis. Only 12 (28.6%) of 42 skin strains and 14 (31.1%) of 45 catheter hub strains were found to be present at the time of catheter removal. In addition, only 9 (29.0%) of the 31 tip-colonizing strains were present on TSSs. Moreover, 15 (48.4%) of the 31 tip-colonizing strains had a superficial origin, and the other 16 (51.6%) were of unknown origin. In catheters suspected of infection, cultures of TSSs had a negative predictive value for catheter-related bacteremia of 94.4% but a positive predictive value of 44.4%. When the causative agent was identified (to the strain level) these values dropped to 80.9 and 18.7%, respectively. The study shows that skin and catheter hub colonization is a common, dynamic phenomenon. Strains recovered from TSSs showed a low level of correlation with strains from previous cultures of specimens from superficial sites and catheter tip isolates. Consequently, TSSs cannot be recommended for use in determining the therapy. However, catheter-related bacteremia is uncommon when cultures of TSSs are negative. PMID:9196194

    Background: Peripheral venous catheters are frequently used in hospitalized patients but increase the risk of nosocomial bloodstream infection. Evidence-based guidelines describe specific steps that are known to reduce infection risk. However, the degree of guideline implementation in clinical practice is not known. The aim of this study was to determine the use of specific steps for insertion of peripheral venous catheters in clinical practice and to implement a multimodal intervention aimed at improving both compliance and the optimum order of the steps. Methods: The study was conducted at University Hospital Hamburg. An optimum procedure for inserting a peripheral venous catheter was defined based on three evidence-based guidelines (WHO, CDC, RKI) including five steps with 1A or 1B level of evidence: hand disinfection before patient contact, skin antisepsis of the puncture site, no palpation of treated puncture site, hand disinfection before aseptic procedure, and sterile dressing on the puncture site. A research nurse observed and recorded procedures for peripheral venous catheter insertion for healthcare workers in four different departments (endoscopy, central emergency admissions, pediatrics, and dermatology). A multimodal intervention with 5 elements was established (teaching session, dummy training, e-learning tool, tablet and poster, and direct feedback), followed by a second observation period. During the last observation week, participants evaluated the intervention. Results: In the control period, 207 insertions were observed, and 202 in the intervention period. Compliance improved significantly for four of five steps (e.g., from 11.6% to 57.9% for hand disinfection before patient contact; p<0.001, chi-square test). Compliance with skin antisepsis of the puncture site was high before and after intervention (99.5% before and 99.0% after). Performance of specific steps in the correct order also improved (e.g., from 7.7% to 68.6% when three of five steps

    Catheter-related blood stream infection (CRBI) is a major cause of morbidity and mortality, and is a source of significant healthcare expenditures in patients that require central venous catheters for intravenous nutrition, chemotherapy, and other products. The source of many catheter-related infections is contamination of the catheter hub. Herein an antimicrobial catheter cap, the AB Cap is described. The AB Cap device is a catheter cleaning device designed to keep needleless luer valves clean by encapsulating them in a cleaning solution. This device was evaluated using an in vitro model of hub contamination with Staphylococcus aureus, Staphylococcus epidermidis (S. epidermidis), Klebsiella pneumonia (K. pneumonia), Pseudomonas aeruginosa, Escherichia coli and Candida albicans (C. albicans). Following hub contamination on days 1, 3, 5 and 7, saline was infused through the AB Cap and effluent collected from the efferent end. The effluent fluid was cultured for the index organisms, and allowed to incubate in culture for up to 7 days. Negative control caps were not contaminated and positive controls lacked cleaning solution and were contaminated. Microbial growth developed for all index organisms, and generally within 1 day of culture growth following the first day of contamination (day 1) in effluent from all positive controls, while no growth occurred in effluent from negative controls. No growth of any organism occurred in any of the test items after the first day of contamination. Growth of three organisms was detected in two of the three test AB Caps following contamination day 3, after 1-4 days of incubation. All organisms could be cultured in the effluent from two of the three test items at contamination day 5, generally by the second day of incubation. One test item remained free of growth for the entire test period except for one organism. By day 7, this particular test item grew an additional organism and the testing was concluded. All positive growth test

    Colorectal cancer patients with central venous catheters (CVC) for pharmacokinetic modulating chemotherapy (PMC) have a substantial risk of venous thromboembolism (VTE). PMC, designed as a hybrid of lower metronomic and higher shorter plasma 5-FU concentrations, has been clinically successful. To determine the effectiveness and safety of D-dimer tests and multidetector-row CT (MDCT) for diagnosis in cancer patients with suspected VTE, we carried out a clinical outcome study on PMC outpatients. Patients received a D-dimer test before and after commencing the PMC regimen. MDCT was performed additionally if the D-dimer test appeared positive or showed signs of VTE. When CT results were positive for thromboembolism, anticoagulation was started. The overall prevalence of VTE in PMC patients was 2.0% (7 of 350 patients). In this study, 34 out of 102 colorectal cancer patients gave a positive D-dimer test (33.3%). CT identified venous thrombi in 2 of the 102 patients (2.0%), mural thrombosis on catheterized veins in another 3 patients (2.9%), and endothelial hyperplasia on catheterized veins in 8 patients (7.8%). The catheters of these patients did not show any significant abnormalities. Patients with negative D-dimer tests showed no signs or symptoms of VTE. In colorectal cancer patients receiving continuous 5-FU infusion via CVC, a D-dimer test can be safely used as the primary diagnostic test for ruling out VTE. We suggest 7.0 microg/ml as the D-dimer cut-off value. Thromboprophylaxis should be considered in the patients showing values >7.0 microg/ml.

    To compare median patency times after treatment of malfunctioning tunneled hemodialysis catheters by one of three techniques: over-the-wire catheter exchange (CE), fibrin sheath stripping (FSS) from a femoral vein approach, and over-the-wire catheter removal with balloon dilation of fibrin sheath (DFS) followed by catheter replacement with use of the same tract. Retrospective study was conducted of 66 consecutive procedures performed over a period of 47 months for poor flow through tunneled hemodialysis catheters despite tissue plasminogen activator infusion trials (CE, n=33; FSS, n=18; DFS, n=15). Baseline parameters (time since initial catheter placement, number of previous catheter interventions, catheter access site, and patient age and sex) were recorded to identify possible pretreatment differences among groups. Outcome comparison was based on duration of adequate catheter function on dialysis during follow-up. No significant differences in baseline parameters were identified among the three groups (P>.05). Mean follow-up duration (67+/-89 days; range, 0-398 d) was similar among the three groups. The immediate technical success rate was 100%, and there were no complications. Cumulative catheter patency rates were 73% (CE), 72% (FSS), and 65% (DFS) at 1 month; 43% (CE), 60% (FSS), and 39% (DFS) at 3 months; and 28% (CE), 45% (FSS), and 39% (DFS) at 6 months. Median duration of patency was similar among groups (P=.60). All three therapies were equivalent in terms of immediate technical success, complication rates, and durability of catheter function during later follow-up. Hence, when one technique is chosen over another, factors other than the period of secondary patency should be considered, such as cost and patient and physician preference.

    Abstract Objective: to identify the model, average length of stay on site and complications of central venous catheter in patients undergoing transplant of hematopoietic stem cells and verify the corresponding relationship between the variables: age, gender, medical diagnosis, type of transplant, implanted catheter and insertion site. Method: a retrospective and quantitative study with a sample of 188 patients transplanted records between 2007 and 2011. Results: the majority of patients used Hickman catheter with an average length of stay on site of 47.6 days. The complication fever/bacteremia was significant in young males with non-Hodgkin's lymphoma undergoing autologous transplant, which remained with the device for a long period in the subclavian vein. Conclusion: nurses should plan with their team the minimum waiting time, recommended between the catheter insertion and start of the conditioning regimen, as well as not to extend the length of time that catheter should be on site and undertake their continuing education, focusing on the prevention of complications.

    Limited data on the risk of peripherally inserted central venous catheter-associated bloodstream infections (PICC BSIs) in hospitalized patients are available. In 2007, dedicated intravenous therapy nurses were no longer available to place difficult peripheral intravenous catheters or provide PICC care Barnes-Jewish Hospital. To determine the hospital-wide incidence of PICC BSIs and to assess the effect of discontinuing intravenous therapy service on PICC use and PICC BSI rates. A 1,252-bed tertiary care teaching hospital. A 31-month retrospective cohort study was performed. PICC BSIs were defined using National Healthcare Safety Network criteria. In total, 163 PICC BSIs were identified (3.13 BSIs per 1,000 catheter-days). PICC use was higher in intensive care units (ICUs) than non-ICU areas (PICC utilization ratio, 0.109 vs 0.059 catheter-days per patient-day for ICU vs non-ICU; rate ratio [RR], 1.84 [95% confidence interval {CI}, 1.78-1.91]). PICC BSI rates were higher in ICUs (4.79 vs 2.79 episodes per 1,000 catheter-days; RR, 1.7 [95% CI, 1.10-2.61]). PICC use increased hospital-wide after the intravenous therapy service was discontinued (0.049 vs 0.097 catheter-days per patient-day; P =.01), but PICC BSI rates did not change (2.68 vs 3.63 episodes per 1,000 catheter-days; P =.06). Of PICC BSIs, 73% occurred in non-ICU patients. PICC use and PICC BSI rates were higher in ICUs; however, most of the PICC BSIs occurred in non-ICU areas. Reduction in intravenous therapy services was associated with increased PICC use across the hospital, but PICC BSI rates did not increase.

    Peripherally-inserted central catheters (PICC) have a greater retention time and less complications compared to central venous catheters (CVC). The study was conducted from From January of 2014 to December 2015 at Beijing DiTan Hospital, Beijing, China, and comprised 70 patients undergoing devascularisation. Of the total, 36(51.4%) patients underwent placement of PICC (Group A), while 34(48.6%) underwent had CVC (Group B). Venous catheterisation was successful in all patients. The median duration of venous catheterization in Group A was greater than that in Group B (p=0.002). Catheter-associated complications did not differ between the groups (p=0.46). The level of blood platelet (PLT) count, Prothrombin activity (PTA) and white blood cell (WBC) count before venous catheterisation were independent risk factors for bleeding at the puncture site and catheter-related infections. A Power PICC may be a better choice than a CVC in patients undergoing devascularisation requiring catheterisation. For patients with a lower PLT count, a decreased PTA, or a decreased WBC, venous catheterisation should be performed with caution.

    Forty-three evaluable patients with hematologic malignancies, mainly acute leukemia, were prospectively randomized to receive a double lumen central venous catheter or a totally implantable venous access system. The mean catheter stay was 166 days (median, 104 days) for the 23 double lumen catheters and 164 days (median, 65 days) for implanted systems. Exit site infections were not encountered in double lumen catheters, but there were two proven infections around the injection port of implanted devices. Tunnel infections did not occur. Seven double lumen catheters and four implanted systems were removed because of infection. Staphylococcus epidermidis was the predominant microorganism cultured from these catheters. Five of nine patients with double lumen catheters and catheter-related S. epidermidis infection and the two patients with implanted systems in whom S. epidermidis was cultured were on selective gut decontamination. The pattern of infection did not seem to be influenced by this regimen. Totally implantable systems proved to be as safe as double lumen central venous lines.

    Heparin locking of venous dialysis catheters is routinely performed in intensive care to maintain catheter patency when the catheters are not being used. Leakage of heparin into the circulation can potentially cause systemic anticoagulation and may present a risk to intensive care patients. To assess the effect of 5000 units per millilitre heparin locking of non-tunnelled dialysis catheters on systemic anticoagulation, we performed a prospective observational study of ten intensive care patients receiving heparin locking of dialysis catheters in an adult tertiary intensive care unit between July and September 2015. Activated partial thromboplastin time (APTT) was measured prior to, and three minutes after, heparin locking of catheter lumens with the manufacturer's recommended locking volume to assess the effect on systemic anticoagulation. Heparin locking of venous dialysis catheters resulted in a significant rise in APTT (P=0.002). The median rise was by 56 seconds (interquartile range 30-166.5). Following heparin locking, 80% of patients had APTT values within or above the range associated with therapeutic anticoagulation. Heparin locking of non-tunnelled venous dialysis catheters can cause systemic anticoagulation in intensive care patients and therefore poses a potential risk to patient safety.

    For most items used in operating rooms, it is unclear whether reusable items are environmentally and financially advantageous in comparison with single-use variants. We examined the life cycles of reusable and single-use central venous catheter kits used to aid the insertion of single-use, central venous catheters in operating rooms. We did not examine the actual disposable catheter sets themselves. We assessed the entire financial and environmental costs for the kits, including the influence of the energy source used for sterilization. For the reusable central venous catheter kit, we performed a "time-in-motion" study to determine the labor costs and measured the energy and water consumption for cleaning and sterilization at Western Health, Melbourne, Australia. For the majority of the inputs for the single-use kit, we relied upon industry and inventory-sourced databases. We modeled the life cycles of the reusable and single-use central venous catheter kits with Monte Carlo analysis. Inclusive of labor, the reusable central venous catheter insertion kits cost $6.35 Australian ($A) (95% confidence interval [CI], $A5.89 to $A6.86), and the single-use kits cost $A8.65. For the reusable kit, CO(2) emissions were 1211 g (95% CI, 1099 to 1323 g) and for the single-use kit 407 g (95% CI, 379 to 442 g). Water use was 27.7 L (95% CI, 27.0 to 28.6 l) for the reusable kit and 2.5 L (95% CI, 2.1 to 2.9 l) for the single-use kit. For the reusable kit, sterilization had the greatest environmental cost, and for the single-use kit, the manufacture of plastic and metal components had the largest environmental costs. Different sources of electricity to make the reusable kits patient-ready again affected the CO(2) emissions: electricity from hospital gas cogeneration resulted in 436 g CO(2) (95% CI, 410 to 473 g CO(2)), from the United States electricity grid 764 g CO(2) (95% CI, 509 to 1174 g CO(2)), and from the European electricity grid 572 g (95% CI, 470 to 713 g CO(2

    Catheter-related blood stream infections (CRBSI) cause significant morbidity and mortality. A retrospective study of a performance improvement project in our teaching hospital's surgical intensive care unit (SICU) showed that intensivist supervision was important in reinforcing maximal sterile barriers (MSB) use during the placement of a central venous catheter (CVC) in the prevention of CRBSI. A historical control period, 1 January 2001-31 December 2003, was established for comparison. From 1 January 2003-31 December 2007, MSB use for central venous line placement was mandated for all operators. However, in 2003 there was no intensivist supervision of CVC placements in the SICU. The use of MSB alone did not cause a significant change in the CRBSI rate in the first year of the project, but close supervision by an intensivist in years 2004-2007, in conjunction with MSB use, demonstrated a significant drop in the CRBSI rate when compared to the years before intensivist supervision (2001-2003), p < .0001. A time series analysis comparing monthly rates of CRBSI (2001-2007) also revealed a significant downward trend, p = .028. Additionally, in the first year of the mandated MSB use (2003), 85 independently observed resident-placed CVCs demonstrated that breaks in sterile technique (34/85), as compared those placements that had no breaks in technique (51/85), had more CRBSI, 6/34 (17.6%) vs. 1/51 (1.9%), p < .01. Interventions to reduce CRBSI in our SICU needed emphasis on adequate supervision of trainees in CVC placement, in addition to use of MSB, to effect lower CRBSI rates.

    Central venous catheters (CVCs) facilitate venous access, allowing the intravenous administration of complex drug treatments, blood products and nutritional support, without the trauma associated with repeated venepuncture. However, CVCs are associated with a risk of infection. Some studies have indicated that the type of dressing used with them may affect the risk of infection. Gauze and tape, transparent polyurethane film dressings such as Tegaderm® and Opsite®, and highly vapour-permeable transparent polyurethane film dressings such as Opsite IV3000®, are the most common types of dressing used to secure CVCs. Currently, it is not clear which type of dressing is the most appropriate. To compare gauze and tape with transparent polyurethane CVC dressings in terms of catheter-related infection, catheter security, tolerance to dressing material and dressing condition in hospitalised adults and children. For this third update, we searched The Cochrane Wounds Group Specialised Register (10 May 2011); The Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library 2011, Issue 2), Ovid MEDLINE (1950 to April Week 4 2011); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, May 11, 2011); Ovid EMBASE (1980 to 2011 Week 18); and EBSCO CINAHL (1982 to 6 May 2011). All randomised controlled trials (RCTs) evaluating the effects of dressing type (e.g. gauze and tape versus transparent polyurethane dressings) on CVC-related infection, catheter security, tolerance to dressing material and dressing condition in hospitalised patients. Two review authors independently assessed trial quality and extracted data. We contacted study authors for missing information. Six studies were included in earlier versions of the review. In this update two of the previously included papers have been excluded and two new trials have been added. Of these six trials, four compared gauze and tape with transparent polyurethane dressings (total participants = 337) and two

    We describe a case of central venous catheter-related fungemia caused by Cryptococcus liquefaciens, a non-neoformans and non-gattii Cryptococcus, in a non-HIV patient. A 71-year-old man with diffuse large B-cell lymphoma receiving antineoplastic chemotherapy was febrile approximately 30 weeks after central venous port insertion, and C. liquefaciens was isolated from all three performed blood cultures as well as a central venous catheter tip culture. In vitro antifungal susceptibility tests showed that this yeast isolate was susceptible to low concentrations of amphotericin B, fluconazole, itraconazole and voriconazole yet was resistant to 5-fluorocytosine (MIC: >64 μg/ml), unlike Cryptococcus neoformans. Treatment of the patient with oral and intravenous voriconazole was effective and consistent with the susceptibility tests. Although non-neoformans and non-gattii Cryptococcus spp. are considered non-pathogenic environmental yeast, they may rarely be the causative agents of serious infections in humans, as in the present case.

    Autologous peripheral blood progenitor cell (PBPC) transplantation frequently requires sequential placement and use of two separate central venous catheters: (1) a short-term, large-bore, stiff device inserted for leukapheresis, and after removal of that device, (2) a long-term, multi-lumen, flexible, Silastic catheter for administration of high-dose chemotherapy, re-infusion of hematopoietic cells, and intensive supportive care. We reviewed our recent experience with two dual-lumen, large-bore, Silastic multi-purpose ('hybrid') catheters, each of which can be used as a single device for both leukapheresis and long-term supportive care throughout the transplant process. Quinton-Raaf PermCath and Bard-Hickman hemodialysis/apheresis dual-lumen catheters were used as the sole venous access device in 112 consecutive patients who underwent autologous PBPC collection and transplantation. The catheter exit site was monitored three times a week, and lumen patency was assessed using clinical and radiologic techniques. Catheters were removed prematurely for persistent thrombus, positive blood cultures despite appropriate antibiotics, or mechanical dysfunction. There were no intra-operative or immediate post-operative complications relating to insertion. Thirty-two patients experienced catheter occlusion necessitating urokinase instillation. Persistent occlusive problems were noted in 16 patients, and in 10 patients the catheter had to be removed. Two exit site infections and 17 bacteremias occurred. Catheters had to be removed for persistent infection in two subjects and for mechanical problems in five others. Cost analysis comparing the hybrid catheters alone vs conventional devices revealed a charge of $4230 in patients with hybrid catheters vs. $7530 in those requiring a temporary non-Silastic dialysis catheter in addition to a flexible, long-term Silastic catheter. Hybrid, Silastic, dual-lumen, large-bore central venous catheters are safe, cost-effective and convenient

    Totally implantable central venous accesses (port-a-cath) are often used for chemotherapy administration or prolonged intravenous infusions in cancer patients. Local and systemic complications may occur both during and after placement of port-a-cath despite the well-established techniques for its placement and care. Out of other catheter-related local complications, thrombosis and infections represent the most common. Complications related to central venous catheter may be associated with infusion of both conventional chemotherapy and molecularly targeted therapy. Incidence and nature of complications of central venous catheter have been well established for long-term chemotherapy. However, very sparse data exists on the incidence of complications of molecularly targeted therapies administered through a central venous catheter. Hence, we decided to retrospectively analyze the local complications of a central venous catheter in patients receiving molecularly targeted therapy and conventional chemotherapy, respectively. Over a 2-year period, 459 devices were placed in two academic Italian institutions. Patients' characteristics, catheter-related complications, and their relationship with targeted therapy administration were retrospectively assessed. Catheter-related complications occurred in 30 out of the 459 analyzed cancer patients (7 %). Local complications occurred in 12 (40 %) and 18 (60 %) patients receiving standard chemotherapy and biological drugs, respectively. Eighteen (72 %) out of 25 patients developing biological complications (BC) were receiving biological drugs. Infusion of a biological drug through a central venous catheter has been shown to increase the risk of central venous catheter complications (p = 0.02). No difference between the incidence of complication between anti-angiogenic and anti-epidermal growth factor receptor (EGFR) agents was observed in our study despite the statistically significant early development of port

    Central venous catheters (CVC) are frequently used for haemodialysis (HD) in children. However, there is paucity of information on the outcomes of CVCs when used for HD in very young patients. Our objective is to report the success, safety and complication rates of CVCs used for HD in children weighing less than 15 kg. This is a single-center retrospective study of all patients with end-stage renal disease (ESRD) weighing <15kg, who underwent a tunneled CVC placement for HD, between July 2006 and June 2012 at our institution. Analysed data included clinical background, age and weight at initiation of HD, outcome of HD, CVC vein insertion site, reason for removal, and catheter survival (in days). Thirty-one CVC were placed in 11 patients weighing <15 kg, 8 males and 3 females. The main causes of ESRD were renal dysplasia and congenital nephrotic syndrome. At the beginning of HD, mean age was 27.5 (range 5-60) months and mean weight was 10.4 kg (4.5-13 kg). The preferred insertion site was the right internal jugular vein (90%). Mean duration of HD was 312 days. Mechanical factors were the main reason for catheter removal (39%). Mean catheter survival was 110 days/catheter. We believe our study provides relevant information and encouraging data to support the use of CVC for HD in this cohort of infants; however, further improvement in prevention of catheter thrombosis and management of infections needs to be achieved.

    To determine the efficacy and tolerability of octenidine hydrochloride, a non-alcoholic skin antiseptic, for the care of central venous catheter (CVC) insertion sites. Prospective, observational study. Bone marrow transplantation unit of a university hospital. All consecutive patients with a nontunneled CVC were enrolled prospectively after informed consent. Octenidine hydrochloride (0.1%) was applied for disinfection at the CVC insertion site during dressing changes. The following cultures were performed weekly as well as at the occurrence of any systemic inflammatory response syndrome criteria: cultures of the skin surrounding the CVC entry site, cultures of the three-way hub connected to the CVC, blood cultures, and cultures of the CVC tip on removal. Enhanced microbiological methods (skin swabs of a 24-cm2 standardized area, roll plate, and sonication of catheter tips) were applied. One hundred thirty-five CVCs were inserted in 62 patients during the study period and remained for a mean period of 19.1 days, corresponding to 2,462 catheter-days. Bacterial density at the insertion site declined substantially over time, and most cultures became negative 2 weeks after insertion. Only 6 patients had a documented catheter-related bloodstream infection. The incidence density was 2.39 catheter infections per 1,000 catheter-days. No side effects were noted with application of the antiseptic. Disinfection with a skin antiseptic that contains octenidine hydrochloride is highly active and well tolerated. It leads to a decrease in skin colonization over time and may be a new option for CVC care.

    Background Chest radiography after central venous catheter (CVC) insertion is the main method of verifying the catheter location. Despite the widespread use of radiography for detecting catheter position, x-ray may not always be readily available, especially in the operating room. Objectives We aimed to compare contrast-enhanced ultrasonography (CEUS) and chest radiography for detecting the correct location of CVCs. Methods One hundred sixteen consecutive patients with indications for CVC before cardiac surgery were enrolled in this observational study. After catheter insertion, CEUS was performed. Portable radiography was obtained postoperatively in the intensive care unit. Sensitivity, specificity, and predictive values were determined by comparing the ultrasonography results with radiographic findings as a reference standard. Results Chest radiography revealed 16 CVC misplacements: two cases of intravascular and 14 cases of right atrium (RA) misplacement. CEUS detected 11 true catheter malpositionings in the RA, while it could not recognize seven catheter placements correctly. CEUS showed two false RA misplacements and five falsely correct CVC positions. A sensitivity of 98% and specificity of 69% were achieved for CEUS in detecting CVC misplacements. Positive and negative predictive values were 95% and 85%, respectively. The interrater agreement (kappa) between CEUS and radiography was 0.72 (P < 0.001). Conclusions Despite close concordance between ultrasonography and chest radiography, CEUS is not a suitable alternative for standard chest radiography in detecting CVC location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting CVC location on a real-time basis in the operating room cannot be ignored.

    Present guidelines recommend culturing only central venous catheter (CVC) tips from patients with suspected catheter-related bloodstream infection (CR-BSI). However, a high proportion of these suspicions are not confirmed. Moreover, CVC tip culture increases laboratory workload, and reports of colonization may be meaningless or misleading for the clinician. Our working hypothesis was that CVC tips should be refrigerated and cultured only in patients with positive blood cultures. We evaluated the effect of 6-day refrigeration of 215 CVC tips. We selected all the catheters with a significant count according to the Maki's roll-plate technique and randomly assigned them to 2 groups. In group A, the catheters were recultured after 24 h of refrigeration, and in group B, the catheters were recultured after 6 days more of refrigeration, so that the refrigeration time evaluated would be of 6 days. The yield of refrigerated CVC tips that grow significant colony counts of primary culture in group B was compared with the yield of refrigerated catheter tips in group A. The difference showed that 6-day refrigeration reduced the number of significant CVCs by 15.2%. Only 61 CVCs were obtained from patients with CR-BSI, and in most of them, blood cultures were already positive before CVC culture, so only 0.91% of the CR-BSI episodes would have been misdiagnosed as culture negative after refrigeration. Refrigeration of CVC tips sent for culture and culturing only those from patients with positive blood cultures reduce the workload in the microbiology laboratory without misdiagnosing CR-BSI.

    To describe the intensive care units (ICU) current infection control practices regarding the management of central venous catheters (CVCs) in Yemeni hospitals and compare the current practices with the evidence-based guidelines. This study was carried out in ICUs of Sana'a hospitals, Republic of Yemen, in July 2010. We gathered the data regarding the infection control practices associated with CVC management in 25 ICUs of 14 hospitals. A self-administered questionnaire was distributed to ICUs' nurse managers in Sana'a city. The results were analyzed and tabulated using the Statistical Package for Social Sciences software version 11, and compared with the evidence-based guidelines. Only 44% of units had written policies for CVC management. The 2 most commonly used practices that comply with the guidelines were: wearing of gloves and dressing material. None of the units used 2% chlorhexidine solutions. More than half of the units were adherent to the recommended practice for hand hygiene (before and after insertion, accessing, dressing or replacing/repairing of CVC), preferred insertion site, antimicrobial-coated catheters, aseptic technique during catheter insertion and site care, disinfection of intravenous access ports, capping stopcocks and infusion set tips while they are not in use, and CVC replacement/removal. In all other sections, only the minority were adherent to the recommended practices. There is a diversity of current practices and lack of consistent adherence to the evidence-based guidelines for the prevention of intravascular catheter-related infections.

    Central venous catheter infections are the leading cause of healthcare-associated bloodstream infections and contribute significantly to mortality and morbidity in neonatal intensive care units. Moreover, infection poses significant economic consequence which increased hospital costs and increased length of hospital stay. Prevention strategies are detailed in guidelines published by the Centers for Disease Control and Prevention (CDC) in the United States; nevertheless, recent surveys in neonatal units in the United States, and Australia and New Zealand demonstrate these are not always followed. This review discusses the numerous evidence-based strategies to prevent catheter infections including hand hygiene, maximal sterile barriers during insertion, skin disinfection, selection of insertion site, dressings, aseptic non-touch technique, disinfection of catheter hubs/ports, administration set management, prompt removal of catheter, antibiotic locks, systemic antibiotic prophylaxis and chlorhexidine bathing. Furthermore, it will describe different strategies that can be implemented into clinical practice to reduce infection rates. These include the use of care bundles including checklists, education and the use of CVC teams.

    Central venous catheters (CVCs) are important for the treatment of patients with cancer, especially in the perioperative and palliative care settings. These devices not only allow for the administration of chemotherapy, parenteral nutrition, and other intravenous therapies, but they may also improve the patients' quality of life by reducing the need for repeated peripheral venipunctures. Thrombotic and infectious complications are common, especially in the long-term use of CVCs. There are different types of thrombotic complications associated with CVCs, that is, a thrombotic occlusion of the catheter, a mural thrombus at the catheter tip and classical deep vein thrombosis, which occurs most frequently in the upper extremity where the majority of long-term catheters are inserted. Infections are common complications associated with CVCs. Patients with cancer who receive intensive chemotherapy and those patients who undergo hematopoietic stem cell transplantation have a markedly increased risk for insertion site and bloodstream infections. In this review, the epidemiology and risk factors that predispose patients to CVC-related thrombosis and infection are discussed. The diagnostic and therapeutic options according to the published data and the current guidelines are summarized and data for establishing primary and secondary preventative strategies are provided.

    Systemic hypotension is common in very low birthweight preterm infants but the nature of the precipitating cause may be unclear. Targeted neonatal echocardiography (TnEcho) is being increasingly used to support hemodynamic decisions in the neonatal intensive care unit (NICU), including identifying impairments in the transitional circulation of preterm infants, providing timely re-evaluation after institution of therapies and evaluating the placement of indwelling catheters. We present a case of a preterm infant with systemic hypotension and low cardiac output secondary to a large transatrial shunt induced by a malpositioned umbilical venous catheter. Repositioning of the line led to resolution of the hemodynamic disturbance and clinical instability, highlighting the utility of TnEcho in the NICU. PMID:25032055

    Haemothorax is an uncommon and serious complication, occurring most often during or immediately after percutaneous internal jugular and subclavian vein catheterizations. Delayed haemothorax is a rare complication, especially following right-sided catheterization. We report a case of acute yellow phosphorus poisoning with acute liver failure (resulting from rat killer paste ingestion) in a 28-year-old male who developed right-sided haemothorax eight days after placement of right internal jugular central venous catheter. The proposed pathogenesis involves vascular wall erosion by the indwelling catheter tip. Awareness of this complication perhaps avoids unnecessary investigations for other causes of haemothorax such as pulmonary embolism. © Journal of the Association of Physicians of India 2011.

    Three-dimensional (3D) echocardiography is becoming widely available and with novel applications. We report an interesting case of a 68-year-old lady with a central venous thrombosis coincident with both a dialysis catheter infection and a recent pacemaker insertion. Two-dimensional transesophageal echocardiography was unable to delineate whether the thrombosis was involved with the pacemaker wire or due to the tunneled catheter infection. The use of 3D echocardiography was able to produce distinct images aiding diagnosis. This circumvented the need for invasive investigations and inappropriate, high-risk removal of the pacing wire. This case highlights the emerging application of 3D echocardiography in routine nephrology practice. PMID:26688761

    Although deep venous insufficiency is common and important, the anatomy of deep vein valves is poorly understood. The aim of this study was to investigate the location, number and consistency of venous valves in the femoral and popliteal veins in normal subjects. A detailed literature search of PubMed was performed. Abstracts and selected full text articles were scrutinised and relevant studies published between 1949 and 2010 reporting anatomical details of deep vein valves were included. From 7470 articles identified by the initial search strategy, nine studies with a total of 476 legs were included in this review. All studies were cadaveric and subjects ranged from stillborn fetuses to 103 years of age. Studies suggested that femoral veins contain between one and six valves, and popliteal veins contain between zero and four valves. Deep vein valves were consistently located in the common femoral vein (within 5 cm of the inguinal ligament), the femoral vein (within 3 cm of the deep femoral vein tributary) and in the popliteal vein near the adductor hiatus. Valves are consistently located at specific locations in the deep veins of the leg, although there is often significant variability between subjects. Further anatomical and functional studies using new imaging modalities available should target these areas to identify whether certain valves play a more important role in venous disease. This may guide us in the development of new treatment options for patients with deep venous disease. PMID:21740424

    We report a case of a preterm neonate born at 26 weeks' of gestation diagnosed with unilateral diaphragmatic paralysis. This paralysis was a consequence of a phrenic nerve injury due to extravasation of hyperosmolar parenteral nutrition fluid in the upper thorax. Chest X-rays and ultrasonography confirmed the diagnosis. The neonate was treated with prolonged respiratory support and did not require surgical treatment. This report describes a case of hemidiaphragmatic paralysis as a complication of central venous catheter insertion. In neonates, spontaneous recovery of diaphragmatic paralysis is possible. This study concludes that recovery of extravasation injury-induced phrenic nerve palsy in the context of conservative management is possible. PMID:28405492

    Peripherally inserted central venous catheters (PICCs) are of growing interest because they allow intravenous therapies up to several months. The appropriate management of the PICCs is crucial to minimize complications and largely depends on the right information for everyone who cares for the patient. To reach this goal we develop the mobile application "PICC App" to provide the necessary information for all involved persons in the outpatient setting. We expect to be able to report about the PICC App and the results of the usability evaluation with pilot users.

    Clostridium novyi has been associated with a large outbreak of severe infections in injection drug users. A case of bacteraemia with Clostridium butyricum in an injection drug user is reported. During treatment for Staphylococcus aureus osteomyelitis, the patient used an indwelling central venous catheter to inject cocaine. He was admitted with C. butyricum sepsis that responded to broad spectrum antibiotics, including vancomycin. Local investigation for other cases was unrevealing; however, growth of an unusual pathogen in clinical specimens should be investigated as it may represent a sentinel event with public health implications.

    To review the literature on prevention of intravascular catheter-related infections. The MEDLINE database, conference proceedings, and bibliographies of review articles and book chapters were searched for relevant articles. Primary authors were contacted directly if data were incomplete. Studies met the following criteria unless otherwise stated: Trials were prospective and randomized; catheters were inserted into new sites, not into old sites over guidewires; catheter cultures were done by using semi-quantitative or quantitative methods; and, for prospective studies, catheter-related bloodstream infection was confirmed by microbial growth from percutaneously drawn blood cultures that matched catheter cultures. Data on population, methods, preventive strategy, and outcome (measured as catheter-related bloodstream infections) were gathered. The quality of the data was graded by using preestablished criteria. The recommended preventive strategies with the strongest supportive evidence are full barrier precautions during central venous catheter insertion; subcutaneous tunneling short-term catheters inserted in the internal jugular or femoral veins when catheters are not used for drawing blood; contamination shields for pulmonary artery catheters; povidone-iodine ointment applied to insertion sites of hemodialysis catheters; specialized nursing teams caring for patients with short-term peripheral venous catheters, especially at institutions with a high incidence of catheter-related infection; no routine replacement of central venous catheters; antiseptic chamberfilled hub or hub-protective antiseptic sponge for central venous catheters; and use of chlorhexidine-silver sulfadiazine-impregnated or minocycline-rifampin-impregnated short-term central venous catheters if the rate of infection is high despite adherence to other strategies that do not incorporate antimicrobial agents (for example, maximal barrier precautions). Simple interventions can reduce the risk for

    Limitations imposed by the coronary sinus venous anatomy triggered the transseptal approach for endocardial LV lead placement. The alignment of the interatrial septum (IAS) and its neighborhood anatomy does not favor transseptal puncture from the pre-pectoral area. Locating and advancing a pre-pectoral LV lead delivery catheter (PDC) through an opening created in the IAS via femoral transseptal puncture (FTP) is time consuming and technically difficult. We describe a method where the PDC is snare coupled to the femoral transseptal apparatus (FTA). When the FTA is advanced into the left atrium (LA) the coupled PDC follows. The catheter of a 25-mm loop snare kit is replaced with the PDC (SelectSite®). The snare loop is positioned in the right common iliac vein from the pre-pectoral access. The PDC is coupled to the FTA by advancing the transseptal apparatus through the open snare loop. After conventional FTP, the FTA is withdrawn back into the right atrium (RA) over an extra support wire positioned in the LA. The PDC with open snare loop is pulled over the FTA up to the RA. The PDC is advanced to close the snare loop on the extra support wire immediately distal to the tip of the dilator close to the puncture site. The PDC is deflected to align with the FTA. The snare coupled catheters are gently advanced across the IAS into the LA. The PDC is released from the FTA by advancing the snare and opening the loop; the snare is then removed from the PDC. The PDC is deflected and advanced into the left ventricle (LV). After positioning the 4.1 Fr lumen less LV lead, the PDC is sliced and removed. The PDC snare coupled to the FTA was advanced into the LA in all five patients, however, access was lost during catheter manipulation in the one right-sided case. Endocardial LV lead was successfully positioned in all five patients. Snare coupling the pre-pectoral SelectSite® catheter to the FTA is technically simple, reliable and a safe method for transseptal endocardial LV lead

    Bedside vascular ultrasound machines are increasingly available. They are used to facilitate safer vascular access across a number of different specialties. In the electrophysiology laboratory however, where patients are frequently anticoagulated and require the insertion of multiple venous sheaths, anatomical landmark techniques predominate. Despite the high number of vascular complications associated with electrophysiological procedures and the increasing evidence to support its use in electrophysiology, ultrasound remains underutilised. A new standard of care is required. A comprehensive technical report, providing a detailed explanation of this important technique, will provide other electrophysiology centres with the knowledge and justification for adopting ultrasound guidance as their standard practice. We review the increasing body of evidence which demonstrates that routine ultrasound usage can substantially improve the safety of femoral venous access in the electrophysiology laboratory. We offer a comprehensive technical report to guide operators through the process of ultrasound-guided venous access, with a specific focus on the electrophysiology laboratory. Additionally, we detail a novel technique which utilises real-time colour Doppler ultrasound to accurately identify needle tip location during venous puncture. The use of vascular ultrasound to guide femoral venous cannulation is rapid, inexpensive and easily learnt. Ultrasound is readily available and offers the potential to significantly reduce vascular complications in the unique setting of the electrophysiology laboratory. Ultrasound guidance to achieve femoral venous access should be the new standard of care in electrophysiology.

    In the academic trauma unit during initial evaluation and resuscitation of trauma victims, central venous catheters are often placed by multiple operators. There are few data on compliance with accepted, standard sterile practices during such procedures. Prospective data were tabulated from video capture of 144 consecutive central venous catheterizations in a trauma resuscitation unit, during peak hours, by a team of trained video technicians. The physicians were surgical and emergency medicine residents. The number of primary operators (trainees) and secondary operators (mentors) for each line was recorded from the video analysis, as well as physician adherence to the use of maximum barrier precautions (MBP; sterile gown, gloves, full operative drape, cap, and mask). Procedures were stratified by level of urgency: Emergent (n = 7), semi-emergent (n = 20), and elective (n = 113). The subclavian vein was used for 73% of the elective catheter placements. For elective central venous catheters, 99 of 113 primary operators (88%) observed MBP, whereas only 31 of 45 secondary operators (69%) did so (p < or = 0.01). Among the 45 elective central venous catheters placed with a secondary operator, there were four instances of frank contamination (9%). Secondary operators, typically trauma surgery attendings, trauma/critical care fellows, or senior surgical residents, function as mentors in academic institutions and act as role models. Secondary operators participated in many of the studied cases, yet failed to demonstrate consistent use of MBP. In elective central venous catheter placement, those where there was the greatest opportunity to follow MBP, we observed a statistically significant difference in compliance rate between the primary and secondary operators. The study suggests the need to address the performance of the secondary operators and to educate them, as although they may be technically experienced in placing central venous catheters, they may comply less

    Catheter-related thrombosis (CRT) is a serious complication in hematological patients, but the risk factors for its occurrence are not well established. The study objectives were to estimate the incidence of CRT and to identify the risk factors for developing CRT in hematological patients. In a prospective setting, 104 consecutive patients with 200 insertions of central venous catheters were enrolled into the study. The patients were screened for CRT by compression Doppler ultrasound every 10-14 days. Additionally, ultrasonography was performed in the case of clinical symptoms suggesting CRT. Over the course of 6,098 catheter days of follow-up, the incidence of CRT was 13.5 %. In 18/27 cases (66.6 %), radiological evidence of CRT was preceded by clinical symptoms. However, in 9/27 (33.3 %), CRT was clinically asymptomatic. The median times to symptomatic and asymptomatic CRT were 17 (range 1-49) and 8 (range 1-16) catheter days, respectively. In univariate analysis, the risk factors for CRT were exit-site infection (ESI) (P < 0.001), two or more prior chemotherapy lines (P = 0.015), catheter-related blood stream infection (P < 0.001), and Coagulase-negative staphylococci infection (P = 0.002). In multivariate analysis, ESI (OR 5.0; 95 % CI 1.6-6.3; P = 0.006) and two or more prior chemotherapy lines (OR 3.57; 95 % CI 1.27-10.11; P = 0.015) remained significantly associated with the risk of CRT. The results of our study provide information regarding the characteristic features of the patients who are at high risk of thrombosis, for whom Doppler ultrasound screening should be considered.

    We intended to evaluate the risk factors for catheter-related bloodstream infection (CR-BSI) with central venous (CV) catheters. For the hub of the CV line, we used three-way stopcocks in the first year of the study and closed needleless connectors (NCs) in the second year. Background factors included the age and sex of patients; the ward; the specialty service; the CV catheter and its days of placement; and the staff compounding the intravenous infusion, i.e., either nurses, who disinfect hands-free, or pharmacists using clean benches. Outcome factors included positive culture from the blood-related samples and the body temperature estimate. Of a total of 29 221 device-days in 1073 patients, positive cultures showed an overall incidence of 2.26 per 1000 device-days. Multivariate analysis showed a higher odds ratio of positive cultures for the ICU (odds ratio [OR], 4.415; 95% confidence interval [CI], 2.054-9.490]) and for CV catheter placement for more than 30 days (OR, 7.529; 95% CI, 4.279-13.247), but no significance for male sex (OR, 1.752; 95% CI, 0.984-3.119) or for pharmacists' compounding (OR, 2.150; 95% CI, 0.974-4.749). Univariate analysis showed no significance for the following factors: age more than 70 years (OR, 0.968; 95% CI 0.561-1.641), the surgery service (OR, 1.029; 95% CI, 0.582-1.818), double-lumen CV catheters (OR, 0.841; 95% CI, 0.465-1.521), or the NC (1.107; 95% CI, 0.673-1.821). We conclude that the theoretical benefit of the NC, the abolished dead space in the hub, contributed little to the outcomes of blood-related culture. The hands-free disinfection may have resulted in comparable odds ratios for the nurses and the pharmacists compounding the infusions.

    Intravenous prostanoids are the backbone of therapy for advanced pulmonary arterial hypertension (PAH) and have improved long-term outcome and quality of life. Currently, two prostanoids are approved by the US Food and Drug administration for parenteral administration: epoprostenol (Flolan) and treprostinil (Remodulin). Chronic intravenous therapy presents considerable challenges for patients and caregivers who must learn sterile preparation of the medication, operation of the pump, and care of the central venous catheter. Patients are routinely counseled and advised regarding the risks of CR-BSIs and catheter care before central line insertion. Central line infections as well as bacteremia are well documented risks of chronic intravenous therapy and may significantly contribute to morbidity and mortality. Recent reports have suggested a possible increase in CR-BSI; therefore, the Scientific Leadership Council of the Pulmonary Hypertension Association decided to provide guidelines for good clinical practice regarding catheter care. Although data exits regarding patients with central venous catheters and the risk of blood stream infections in patients with cancer or other disorders, there is little data regarding the special needs of patients with pulmonary arterial hypertension requiring central venous access. These guidelines are extrapolated from the diverse body of literature regarding central venous catheter care.

    The authors advise on an exceptional complication in a totally implantable venous access and give recommendations on how to avoid this problem. In an obese person, one week after the implantation of a totally implantable venous access, a chest X-ray showed that the catheter was too short. In the operative room, at the time of the second intervention, the radioscopy did not find this anomaly. The subcutaneous injection port was positioned too low. When the patient was in a supine position, the subcutaneous injection port was in the correct position but when she was in an upright position, the breast descended and pulled down the subcutaneous injection port and the catheter.

    Central venous devices are frequently used in children to monitor haemodynamic status, to administer fluids, medication, parenteral nutrition and for blood sampling. Life-threatening complications that may occur on insertion if the central venous catheter (CVC) is misplaced, are cardiac tamponade or a hydro-/haemopericardium. There is still controversy over the optimum catheter tip position in paediatric patients, whether to place the CVC tip in the superior vena cava, outside the pericardial boundaries or in the right atrium. However, the exact location of the pericardium cannot be seen on a normal chest x-ray. The carina is a radiographic marker for CVC placement, suggested on the basis of studies with conserved and fresh adult cadavers. In order to confirm this landmark for children, the present study was performed with 31 fresh cadavers of small children (mean age 12.5+/-3.4 months) that had been selected for autopsy in the Institute of Legal Medicine. Results clearly demonstrate that the carina was 0.5+/-0.04 cm above the pericardial duplication as it transversed the SVC. In no infant cadaver was the carina inferior to the pericardium. Thus, the results are analogous to those in adults and confirm that the carina is a simple anatomical-radiological landmark, superior to the pericardial reflection, that can be used to identify the placement of CVC even in newborn and small children.

    ABSTRACT Objective: to evaluate the use of peripheral venous catheters based on microbiological analysis of devices (dressing and three-way stopcocks) and thus contribute to the prevention and infection control. Methods: this was a prospective study of microbiological analysis of 30 three-way stopcocks (external surfaces and lumens) and 30 dressing used in maintaining the peripheral venous catheters of hospitalized adult patients. Results: all external surfaces, 40% of lumens, and 86.7% of dressing presented bacterial growth. The main species isolated in the lumen were 50% coagulase-negative Staphylococcus, 14.3% Staphylococcus aureus, and 14.3% Pseudomonas aeruginosa. Fifty nine percent of multidrug-resistant bacteria were isolated of the three-way stopcocks, 42% of the lumens, and 44% of the dressing with a predominance of coagulase-negative Staphylococcus resistant to methicillin. Besides, 18% gram-negative bacteria with resistance to carbapenems were identified from multidrug-resistant bacteria on the external surfaces of the three-way stopcocks. Conclusion: it is important to emphasize the isolation of coagulase-negative Staphylococcus and gram-negative bacteria resistant to methicillin and carbapenems in samples of devices, respectively, which reinforces the importance of nursing care in the maintenance of the biologically safe environment as well as prevention and infection control practices.

    An ultrasound investigation was undertaken of the neck region of 42 patients with normal neck anatomy in order to determine whether the results of ultrasound-gained topographical data provided pointers to the choice of entry site to the internal jugular vein (IJV). In addition, the IJV was punctured under ultrasound control in 23 patients in an intensive care unit in whom there was a problem of increased bleeding tendency, anatomical difficulty or previously failed "blind" puncture. In all of them a central venous catheter was placed without complication by the Seldinger technique via the primary chosen point for puncture. An approach through the sternocleidomastoid muscle, between the cricoid level and the "central" place of puncture between the two bellies of the sternocleidomastoid muscle proved to be the most satisfactory compromise between easy application of the ultrasound head, large vein diameter and reduction of any risk of mistakenly puncturing artery or pleura. This approach has to be varied according to the ultrasound findings. It is concluded from this experience that ultrasound is suitable for the placement of central venous catheters. But since the equipment is bulky it cannot be used in an emergency.

    Transvenous lead extraction can be a method to regain venous access. We present the case of a man, aged 67, with indications to upgrade an ICD to a resynchronization therapy device. Since innominate vein occlusion was diagnosed and extraction of an abandoned ventricular pacing lead did not provide lumen regain, a functional atrial lead was extracted with the femoral approach to stabilization and venous access was regained. Asymptomatic vein wall damage but no other complications were recorded. The simultaneous application of different techniques to regain venous access may allow success of the final procedure in system upgrading.

    Candidemia causes significant morbidity and mortality among children. Removal of a central venous catheter (CVC) is often recommended for adults with candidemia to reduce persistent and metastatic infection. Pediatric-specific data on the impact of CVC retention are limited. A retrospective cohort study of inpatients <19 years with candidemia at the Children's Hospital of Philadelphia between 2000 and 2012 was performed. The final cohort included patients that had a CVC in place at time of blood culture and retained their CVC at least 1 day beyond the blood culture being positive. A structured data collection instrument was used to retrieve patient data. A discrete time failure model, adjusting for age and the complexity of clinical care before onset of candidemia, was used to assess the association of CVC retention and 30-day all-cause mortality. Two hundred eighty-five patients with candidemia and a CVC in place at the time of blood culture were identified. Among these 285 patients, 30 (10%) died within 30 days. Central venous catheter retention was associated with a significant increased risk of death on a given day (odds ratio, 2.50; 95% confidence interval, 1.06-5.91). Retention of a CVC was associated with an increased risk of death after adjusting for age and complexity of care at candidemia onset. Although there is likely persistence of unmeasured confounding, given the strong association between catheter retention and death, our data suggest that early CVC removal should be strongly considered. © The Author 2015.

    The use of peripherally inserted central catheter (PICC) line for central venous access in thermally injured patients has increased in recent years despite a lack of evidence regarding safety in this patient population. A recent survey of invasive catheter practices among 44 burn centers in the United States found that 37% of burn units use PICC lines as part of their treatment protocol. The goal of this study was to compare PICC-associated complication rates with the existing literature in both the critical care and burn settings. The methodology involved is a single institution retrospective cohort review of patients who received a PICC line during admission to a regional burn unit between 2008 and 2013. Fifty-three patients were identified with a total of seventy-three PICC lines. The primary outcome measurement for this study was indication for PICC line discontinuation. The most common reason for PICC line discontinuation was that the line was no longer indicated (45.2%). Four cases of symptomatic upper extremity deep vein thrombosis (5.5%) and three cases of central line-associated bloodstream infection (4.3%, 2.72 infections per 1000 line days) were identified. PICC lines were in situ an average of 15 days (range 1 to 49 days). We suggest that PICC line-associated complication rates are similar to those published in the critical care literature. Though these rates are higher than those published in the burn literature, they are similar to central venous catheter-associated complication rates. While PICC lines can be a useful resource in the treatment of the thermally injured patient, they are associated with significant and potentially fatal risks.

    The lack of technical information from suppliers and from the literature, a wide variety of features and the absence of medical device reference document explain the difficulty for medical and pharmaceutical staffs to choose a central venous catheter (CVC). The aim of this study was to establish the specifications to choose a CVC according to the clinician needs. An analysis of suppliers' technical documentation and a literature review was performed to identify criteria and to collect them in a questionnaire to conduct semi-structured interviews between 1 pharmacist and 5 anaesthesiologists/intensivists. With these interviews, the technical criteria were classified according to their importance in 3 levels. Thirteen technical criteria were identified after reading the technical documents and the literature. Among them, 8 were classified as "essential criteria" (level I) by the physicians: J-shaped guide, one clamp on each way, identified lumen, radiopacity, graduation every centimeter by 5 to 20 cm from the distal extremity, a length of 15 to 25 cm, a single-lumen catheter with a 14 to 16G way and a three-lumen catheter with 14 to 18G way. Finally, three criteria were classified as "intermediate criteria" (level II) and two as "optional criteria" (level III). This collaborative approach allowed to reference new medical devices according to the clinicians needs. These CVC are a mean to respect guidelines for physicians and nurses and to secure the patient's care. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    To evaluate dialysis history, imaging findings and outcome of endovascular treatment in six patients with central venous stenosis without a history of previous catheter placement. Between April 2000 and June 2004, six (10%) of 57 haemodialysis patients had stenosis of a central vein without a previous central catheter placement. Venography findings and outcome of endovascular treatment in these six patients were retrospectively evaluated. Patients were three women (50%) and three men aged 32-60 years (mean age: 45 years) and all had massive arm swelling as the main complaint. The vascular accesses were located at the elbow in five patients and at the wrist in one patient. Three patients had stenosis of the left subclavian vein and three patients had stenosis of the left brachiocephalic vein. The mean duration of the vascular accesses from the time of creation was 25.1 months. Flow volumes of the vascular access were very high in four patients who had flow volume measurement. The mean flow volume was 2347 ml/min. One of three patients with brachiocephalic vein stenosis had compression of the vein by the brachiocephalic artery. All the lesions were first treated with balloon angioplasty and two patients required stent placement on long term. Number of interventions ranged from 1 to 4 (mean: 2.1). Symptoms resolved in five patients and improved in one patient who had a stent placed in the left BCV. Central venous stenosis in haemodialysis patients without a history of central venous catheterization tends to occur or be manifested in patients with a proximal permanent vascular access with high flow rates. Balloon angioplasty with or without stent placement offers good secondary patency rates in mid-term.

    Background There is little data comparing catheter-directed thrombolysis (CDT) via small saphenous veins vs. systematic thrombolysis on complications and efficacy in acute deep venous thrombosis patients. The aim of our study was to compare the efficacy and safety of CDT via the small saphenous veins with systematic thrombolysis for patients with acute deep venous thrombosis (DVT). Material/Methods Sixty-six patients with acute DVT admitted from June 2012 to December 2013 were divided into 2 groups: 27 patients received systemic thrombolysis (ST group) and 39 patients received CDT via the small saphenous veins (CDT group). The thrombolysis efficiency, limb circumference differences, and complications such as post-thrombotic syndrome (PTS) in the 2 groups were recorded. Results The angiograms demonstrated that all or part of the fresh thrombus was dissolved. There was a significant difference regarding thrombolysis efficiency between the CDT group and ST group (71.26% vs. 48.26%, P=0.001). In both groups the postoperative limb circumference changes were higher compared to the preoperative values. The differences between postoperative limb circumferences on postoperative days 7 and 14 were significantly higher in the CDT group than in the ST group (all P<0.05). The incidence of postoperative PTS in the CDT group (17.9%) was significantly lower in comparison to the ST group (51.85%) during the follow-up (P=0.007). Conclusions Catheter-directed thrombolysis via the small saphenous veins is an effective, safe, and feasible approach for treating acute deep venous thrombosis. PMID:27552357

    Central line-associated bloodstream infection (CLABSI) is the major complication of central venous catheters (CVC). The aim of the study was to test the effectiveness of a hospital-wide strategy on CLABSI reduction. Between 2008 and 2011, all CVCs were observed individually and hospital-wide at a large university-affiliated, tertiary care hospital. CVC insertion training started from the 3rd quarter and a total of 146 physicians employed or newly entering the hospital were trained in simulator workshops. CVC care started from quarter 7 and a total of 1274 nurses were trained by their supervisors using a web-based, modular, e-learning programme. The study included 3952 patients with 6353 CVCs accumulating 61,366 catheter-days. Hospital-wide, 106 patients had 114 CLABSIs with a cumulative incidence of 1.79 infections per 100 catheters. We observed a significant quarterly reduction of the incidence density (incidence rate ratios [95% confidence interval]: 0.92 [0.88-0.96]; P<0.001) after adjusting for multiple confounders. The incidence densities (n/1000 catheter-days) in the first and last study year were 2.3/1000 and 0.7/1000 hospital-wide, 1.7/1000 and 0.4/1000 in the intensive care units, and 2.7/1000 and 0.9/1000 in non-intensive care settings, respectively. Median time-to-infection was 15 days (Interquartile range, 8-22). Our findings suggest that clinically relevant reduction of hospital-wide CLABSI was reached with a comprehensive, multidisciplinary and multimodal quality improvement programme including aspects of behavioural change and key principles of good implementation practice. This is one of the first multimodal, multidisciplinary, hospital-wide training strategies successfully reducing CLABSI.

    We compared two routes for myocardial delivery of therapeutics, transendocardial (TE) delivery with an intramyocardial injection catheter, and retrograde coronary venous (RCV) delivery with a balloon occlusion catheter in the interventricular vein. TE and RCV injection of 15 microM, neutron-activatable microspheres was compared in healthy pigs (Group I, n = 3), pigs with a 1-week-old myocardial infarction (MI; group II, n = 5), and pigs with a 2-weeks-old MI (group III, n = 4). The MI was induced by a 1-hr balloon occlusion in the LAD. Both methods were compared in the same animal using different microspheres. The RCV catheter allowed for continuous measurement of distal pressure and 2.5 x 10(6) microspheres were injected in 10 ml at 300 mmHg above balloon occlusion pressure. The TE injections were targeted to the infarct zone and 2.5 x 10(6) microspheres were distributed over 10 injections of 200 microl. The retention of microspheres decreased with increase in MI age, but was comparable between devices within the groups. RCV delivery resulted in (14.3 +/- 0.9)% microsphere retention in Group I, (10.3 +/- 0.2)% in Group II, and (6.4 +/- 0.1)% in group III (P < 0.05 versus group I). Microsphere retention after TE was (15.1 +/- 0.7)% in group I, (18.9 +/- 0.6)% in group II, (4.1 +/- 0.1)% in Group III (P < 0.05 versus groups I and II). The RCV catheter delivered primarily to midventricular, antero-septal segments, whereas TE targeted apical areas predominantly. Delivery efficacy was comparable between devices in each group however RCV targeted midventricular areas whereas TE targeted apical areas.

    We report two cases of a retained guide wire after perioperative placement of a central venous catheter during a six-month period. Case 1: A 73-year-old male was scheduled for an open cholecystectomy and hepatectomy. After induction of anesthesia, a central venous (CV) catheter was inserted via the right internal jugular vein using an ultrasound guide. Chest radiographs showed a retained guide wire in the inferior vena cava immediately after surgery, which was removed by interventional radiologist before the patient emerged from anesthesia. Case 2: A 77-year-old male was scheduled for colostomy closure. The surgeon inserted a CV catheter in the right internal jugular vein 4 days before the colostomy. Chest radiographs revealed a retained guide wire in the inferior vena cava, which was removed by interventional radiologists before the patient emerged from anesthesia. Although a retained guide wire is a rare complication, awareness of this mishap is necessary to prevent it from happening.

    Intravenous catheters are used for the administration of intravenous therapy and for blood sampling. These devices are considered as well-functioning if both the injection and aspiration are easy. Malfunction is frequently observed and usually vaguely described as occlusion. We developed the CINAS, the Catheter Injection and Aspiration scheme. The CINAS is a catheter function classification tool, which classifies both the injection and the aspiration ability in a uniform way. Each CINAS class consists of a combination of an injection (IN) and an aspiration (AS) code: e.g. IN1AS1 is the CINAS class for a well-functioning catheter. In this series, we aimed to determine the accuracy of the CINAS class reported by nurses, after minimal training, versus a trained researcher, acting as a reference standard. Catheter function was assessed during a standard blood sampling procedure through a totally implantable venous access device in a convenience sample of 150 oncology patients. One nurse researcher and 111 oncology nurses both scored the catheter function according to the CINAS classification scheme, independently. Concordance between the scores was calculated. For the 140 catheters scored as well-functioning (IN1AS1 score) by the researcher, 139 or 99.3 % (95 % confidence interval (CI) 96.1-99.9 %) were scored correctly by the nurse participants. Nine out of ten or 90 % (95 % CI 55.5-98.3 %) of malfunctioning catheters (researcher scores different from IN1AS1) were also identified as malfunctioning by the nurse participants and received exactly the same CINAS score in eight cases (80 %, 95 % CI 44.4-97.5 %). The overall accuracy of the CINAS scored by the nurse participants versus the researcher is (139 + 9)/150 or 98.7 % (95 % CI 95.3-99.8 %). Nurse participants were able to classify the catheter function of totally implantable venous access devices with the CINAS accurately after a brief explanation about the classification options.

    Post-thrombotic syndrome secondary to iliofemoral deep venous thrombosis is a significant contributor to advanced chronic venous insufficiency. Iliac vein stenting is a standard procedure to treat iliocaval obstruction. In cases with obstruction extending across the groin, venous inflow for an iliac vein stent may be poor and compromise results of iliac vein stenting. Treatment options include extension of stents across the inguinal ligament that may have limitations in improving inflow only from only one vessel. Endovenectomy in this scenario becomes an attractive option with or without iliac vein stenting to provide outflow to the profunda vein, which otherwise is "axially transformed" in chronic iliofemoral deep venous thrombosis. We describe a technique of endovenectomy in combination with iliac vein stenting to establish a patent outflow tract for profunda and femoral veins. Accompanying also is a video demonstration of endovenectomy that will help viewers understand more technical aspects of the procedure.

    Central venous catheters (CVCs) are used for vascular access in hemodialysis patients who have no alternative access or are awaiting placement or maturation of a permanent access. The major complications of CVCs are catheter-related bloodstream infection and clotting in the catheter lumen. Parallel-group, randomized, multicenter clinical trial, with patients blinded to study intervention. 16 free-standing dialysis facilities in Northern California belonging to a single provider. 303 adult maintenance hemodialysis patients who were using a tunneled cuffed CVC for vascular access. The treatment group received an antibiotic lock containing gentamicin 320 μg/mL in 4% sodium citrate, whereas the control group received the standard catheter lock containing heparin 1,000 U/mL. Both groups received triple-antibiotic ointment on the catheter exit site during dressing changes at each dialysis treatment. Catheter-related bloodstream infection and catheter clotting. Catheter-related bloodstream infection was defined as the occurrence of symptoms consistent with bacteremia together with positive blood culture results in the absence of another obvious source of infection. Catheter clotting was measured as the rate of thrombolytic agent use required to maintain adequate blood flow. A single patient could contribute more than one infection or clotting episode. The rate of catheter-related bloodstream infection was 0.91 episodes/1,000 catheter-days in the control group and 0.28 episodes/1,000 catheter-days in the treatment group (P = 0.003). The time to the first episode of bacteremia was significantly delayed (P = 0.005). The rates of tissue plasminogen activator use were similar in the treatment and control groups: 2.36 versus 3.42 events/1,000 catheter-days, respectively (P = 0.2). The requirement for dialysis facility staff to prepare the treatment intervention prevented a completely blinded study. Gentamicin 320 μg/mL in 4% sodium citrate used as a routine catheter lock in

The experimental oesophageal burn was established by the application of 10% sodium hydroxide to the distal oesophagus under a pressure of 20 cmH 2 O, via 5-F double-lumen central venous catheter without a gastrotomy. The control group was given 0.9% sodium chloride. All rats were killed 24 h after administration of NaOH or 0.9% NaCl. Histologic damage to oesophageal tissue was scored by a single pathologist blind to groups. The rats in the control group were observed to have no pathological changes. Corrosive oesophagitis (tissue congestion, oedema, inflammation, ulcer and necrosis) was observed in rats exposed to NaOH. We believe that an experimental corrosive oesophageal burn can safely be created under same hydrostatic pressure without a gastric puncture using this model.

    The tendency of medium- and long-term silicone central venous catheters (CVCs) to block, fracture, and become displaced has led to the evaluation of a polyurethane CVC, Cuff Cath (Viggo Spectramed, Swindon, Wilts, United Kingdom) as a possible alternative because polyurethane is smoother and stronger. We report the first prospective study of polyurethane cuffed CVCs in children. Sixty Cuff Caths were placed in 53 children, mean age 4.7 years (range, 4 days to 16.3 years), mean weight 15.6 kg (range, 3.1 to 58 kg). All CVCs were tunnelled (mean tunnel length, 12 cm; range, 5 to 20 cm) and inserted either into the subclavian vein (n = 28) or internal jugular vein (n = 32). In a total of 6363 catheter days (mean, 111 days per patient; range, 15 to 364 days), three (5%) CVCs had to be removed because of sepsis and one (2%) because of blockage. All other Cuff Caths remained patent to infusion and blood sampling. No Cuff Caths were pulled or fell out, fractured, or migrated. This study demonstrates significant advantages of polyurethane compared with previous series using silicone CVCs with respect to blockage, fragmentation, and dislodgement. A prospective, randomized, controlled trial of Cuff Cath compared with a silicone CVCs in children is required.

    To evaluate the effects of the central venous catheter self-management education program (CVC S-MEP) in improving knowledge, attitude, and behavior regarding CVC and in decreasing CVC-related complications in patients with cancer during homecare service. A quasi-experimental, sequential cohort design study of patients with cancer and who have CVCs was performed to compare the effect of CVC S-MEP with usual care. The study group consisted of 45 participants (26 male and 19 female), and the mean age was 46.1 (SD, 10.5) years. The subjects of the CVC S-MEP had significantly high mean levels of self-management knowledge (p = 0.007), attitude (p < 0.001), and behavior (p = 0.002). Also, the participants in the CVC S-MEP had significantly lower frequency of catheter-related complications (p = 0.030). The CVC S-MEP helped improve patients' ability to resolve problems and adequately respond to CVC-related emergency situations by fostering greater self-care ability. Additionally, providing practical information for CVC self-management in a gradual and repetitive manner had a notable positive effect on patients. Copyright © 2016 Elsevier Ltd.

    To understand the vulnerability of patients with cancer to central line-associated bloodstream infections related to tunneled central venous catheters (CVCs), patients were asked to describe their line care at home and in clinic and to characterize their knowledge and experience managing CVCs. Forty-five adult patients with cancer were recruited to participate. Patients were interviewed about the type of line, duration of use, and observations of variations in line care. They also were asked about differences between line care at home and in the clinic, precautions taken when bathing, and their education regarding line care. Demographic information and primary cancer diagnosis were taken from the patients' medical records. Patients with hematologic and gastrointestinal malignancies were heavily represented. The majority had tunneled catheters with subcutaneous implanted ports. Participants identified variations in practice among nurses who cared for them. Although many participants expressed confidence in their knowledge of line care, some were uncertain about what to do if the dressing became loose or wet, or how to recognize an infection. Patients seemed to be astute observers of their own care and offered insights into practice variation. Their observations show that CVC care practices should be standardized, and educational interventions should be created to address patients' knowledge deficits.

    Background: The current study was designed to compare the complications and adverse effects of central venous catheter (CVC) insertion under ultrasound guidance in patients with and without coagulopathy. Materials and Methods: In this clinical trial, 59 patients who needed CVC for various reasons were enrolled. Patients were divided into two groups of those with and without coagulopathy based on complete blood count, prothrombin time, partial thromboplastin time, and international normalized ratio test results, and then, CVC was inserted with ultrasound guidance in both groups. The CVC inserting site was examined for hematoma and hemorrhage in four stages at different times. Results: There was no significant difference in the terms of demographic features, catheter lumen size (P = 0.43), and number of attempting for CVC placement (odds ratio [OR] =2.35, 95% confidence interval [CI] = 0.36–15.3, P = 0.39) between two groups. Seven out of 59 patients suffered from complications (11.9%) that the complications in coagulopathic patients were oozing (5.7%) and superficial hematoma (8.6%) while in noncoagulopathic patients were 4.2% for both complications (OR = 0.54, 95% CI = 0.09–3.07, P = 0.767). Conclusion: According to our results, it can be concluded that inserting CVC with ultrasound guidance under emergency conditions causes no serious and life-threatening complications in coagulopathic patients.

    This study evaluated the effects of urokinase in the prevention of central venous catheter (CVC)-related complications in children with malignancy. Fifteen patients with 16 CVCs (study group A) received an intraluminal application of urokinase (10,000 IU in each catheter lumen for 4 h) once a week. They were monitored prospectively with quantitative blood cultures and ultrasonography (color Doppler ultrasound of the great veins and echocardiography). The rate of complications was compared with that of 15 children with 19 CVCs without thromboprophylaxis, treated the previous significantly lower incidence of CVC dysfunction year (control group B). The authors found a wer incidence of CVC dysfunction (3/16 versus 13/19), no major thrombosis, fewer CVC-related bacteremias (2/16 versus 8/19), and a higher salvage of CVCs (1/16 versus 5/19 CVC removals due to persistent bacteremia) in the thromboprophylaxis group. Asymptomatic thrombosis rate was also lower (7/16 cases in group A versus 9/11 in group B when sonography was performed). No hemorrhagic complications were noted. Thromboprophylaxis with urokinase seems a safe and effective measure for reducing the rate of CVC-related complications.

    Central venous catheter (CVC)-related infections are commonly caused by Staphylococcus epidermidis that is able to form a biofilm on the catheter surface. Many studies involving biofilm formation by Staphylococcus have been published each adopting an own in vitro model. Since the capacity to form a biofilm depends on multiple environmental factors, direct comparison of results obtained in different studies remains challenging. This study characterized the phenotype (strong versus weak biofilm-producers) of S. epidermidis from CVCs in four different in vitro biofilm models, covering differences in material type (glass versus polymer) and nutrient presentation (static versus continuous flow). A good correlation in phenotype was obtained between glass and polymeric surfaces independent of nutrient flow, with 85% correspondence under static growth conditions and 80% under dynamic conditions. A 80% correspondence between static and dynamic conditions on polymeric surfaces could be demonstrated as well. Incubation time had a significant influence on the biofilm phenotype with only 55% correspondence between the dynamic models at different incubation times (48h versus 17h). Screening for the presence of biofilm-related genes only revealed that ica A was correlated with biofilm formation under static but not under dynamic conditions. In conclusion, this study highlights that a high level of standardization is necessary to interpret and compare results of different in vitro biofilm models. Copyright © 2016 Elsevier B.V.

    We performed a systematic review and meta-analysis to examine the accuracy of bedside ultrasound for confirmation of central venous catheter position and exclusion of pneumothorax compared with chest radiography. PubMed, Embase, Cochrane Central Register of Controlled Trials, reference lists, conference proceedings and ClinicalTrials.gov. Articles and abstracts describing the diagnostic accuracy of bedside ultrasound compared with chest radiography for confirmation of central venous catheters in sufficient detail to reconstruct 2 × 2 contingency tables were reviewed. Primary outcomes included the accuracy of confirming catheter positioning and detecting a pneumothorax. Secondary outcomes included feasibility, interrater reliability, and efficiency to complete bedside ultrasound confirmation of central venous catheter position. Investigators abstracted study details including research design and sonographic imaging technique to detect catheter malposition and procedure-related pneumothorax. Diagnostic accuracy measures included pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio. Fifteen studies with 1,553 central venous catheter placements were identified with a pooled sensitivity and specificity of catheter malposition by ultrasound of 0.82 (0.77-0.86) and 0.98 (0.97-0.99), respectively. The pooled positive and negative likelihood ratios of catheter malposition by ultrasound were 31.12 (14.72-65.78) and 0.25 (0.13-0.47). The sensitivity and specificity of ultrasound for pneumothorax detection was nearly 100% in the participating studies. Bedside ultrasound reduced mean central venous catheter confirmation time by 58.3 minutes. Risk of bias and clinical heterogeneity in the studies were high. Bedside ultrasound is faster than radiography at identifying pneumothorax after central venous catheter insertion. When a central venous catheter malposition exists, bedside ultrasound will identify four out of every five earlier than

    Cerebral infarction is one of the serious neurological complications of diabetic ketoacidosis (DKA). Especially in patients who are genetically prone to thrombosis, cerebral infarction may develop due to inflammation, dehydration, and hyperviscocity secondary to DKA. A 6-year-old child with DKA is diagnosed with cerebral infarction after respiratory insufficiency, convulsion, and altered level of consciousness. Femoral and external iliac venous thrombosis also developed in a few hours after central femoral catheter had been inserted. Heterozygous type of factor V Leiden and PAI-14G/5G mutation were detected. In patients with DKA, cerebral infarction may be suspected other than cerebral edema when altered level of consciousness, convulsion, and respiratory insufficiency develop and once cerebral infarction occurs the patients should also be evaluated for factor V Leiden and PAI-14G/5G mutation analysis in addition to the other prothrombotic risk factors.

    Children who require long-term parenteral nutrition (PN) have central venous catheters (CVCs) in place to allow the safe and effective infusion of life-sustaining fluids and nutrition. Many consider recreational swimming to be a common part of childhood, but for some, the risk may outweigh the benefit. Children with CVCs may be at increased risk of exit site, tunnel, and catheter-related bloodstream infections (CRBSIs) if these catheters are immersed in water. The purpose of this review is to evaluate the current literature regarding the risk of infection for patients with CVCs who swim and determine if there is consensus among home PN (HPN) programs on this controversial issue. A total 45 articles were reviewed and 16 pediatric HPN programs were surveyed regarding swimming and CVCs. Due to the limited data available, a firm recommendation cannot be made. Recreational water associated outbreaks are well documented in the general public, as is the presence of human pathogens even in chlorinated swimming pools. As a medical team, practitioners can provide information and education regarding the potential risk, but ultimately the decision lies with the parents. If the parents decide swimming is worth the risk, they are encouraged to use products designed for this use and to change their child's dressing immediately after swimming. Due to our experience with a fatal event immediately after swimming, we continue to strongly discourage patients with CVCs from swimming. Further large and well-designed studies regarding the risk of swimming with a CVC are needed to make a strong, evidence-based recommendation.

    Patient: Male, 50 Final Diagnosis: Retained guidewire removal by interventional radiology Symptoms: Swelling Medication: — Clinical Procedure: Fluoroscopic retrieval of the guidewire Specialty: Critical Care Medicine Objective: Unusual setting of medical care Background: Central venous catheterization is a common tool used in critically ill patients to monitor central venous pressure and administer fluids and medications such as vasopressors. Here we present a case of a missing guide wire after placement of peripherally inserted central catheter (PICC), which was incidentally picked up by bedside ultrasound in the intensive care unit. Case Report: A 50-year-old Hispanic male was admitted to the intensive care unit for alcohol intoxication. He was managed for septic shock and required placement of a peripherally inserted central line in his left upper extremity for antibiotics and vasopressor administration. A bedside ultrasound performed by the intensivist to evaluate upper extremity swelling revealed a foreign body in the left arm. Percutaneous procedure by Interventional radiologist was required for retrieval of the guidewire. Conclusions: Guide wire related complications are rarely reported, but are significantly associated with mortality and morbidity. The use of ultrasound guidance placement of PICC lines decreases the risk of complications, provides better optimal vein selection, and enhances success. PMID:27920421

    Background Simulation training may improve proficiency at and reduces complications from central venous catheter (CVC) placement, but the scope of simulation’s effect remains unclear. This randomized controlled trial evaluated the effects of a pragmatic CVC simulation program on procedural protocol adherence, technical skill, and patient outcomes. Methods Internal medicine interns were randomized to standard training for CVC insertion or standard training plus simulation-based mastery training. Standard training involved a lecture, a video-based online module, and instruction by the supervising physician during actual CVC insertions. Intervention-group subjects additionally underwent supervised training on a venous access simulator until they demonstrated procedural competence. Raters evaluated interns’ performance during internal jugular CVC placement on actual patients in the medical intensive care unit. Generalized estimating equations were used to account for outcome clustering within trainees. Results We observed 52 interns place 87 CVCs. Simulation-trained interns exhibited better adherence to prescribed procedural technique than interns who received only standard training (p=0.024). There were no significant differences detected in first-attempt or overall cannulation success rates, mean needle passes, global assessment scores or complication rates. Conclusions Simulation training added to standard training improved protocol adherence during CVC insertion by novice practitioners. This study may have been too small to detect meaningful differences in venous cannulation proficiency and other clinical outcomes, highlighting the difficulty of patient-centered simulation research in settings where poor outcomes are rare. For high-performing systems, where protocol deviations may provide an important proxy for rare procedural complications, simulation may improve CVC insertion quality and safety. PMID:26154250

    Purpose: The OUTBACK® catheter is a reentry device that enables reentry into a vessel lumen from the subintimal space during subintimal angioplasty. It is reserved for cases where reentry has not been possible using conventional wire and catheter techniques. We report a two-center experience in recanalization of the chronic total occlusions of the common iliac (CIA) and the superficial femoral artery (SFA) using the OUTBACK® catheter in cases where other techniques were unsuccessful. Material and Methods: All cases where recanalization was performed using the OUTBACK® reentry catheter between January 2010 to January 2015 were retrospectively identified and included in this study. 21 patients were identified. The indication for intervention in these cases included claudication and critical leg ischemia. In all cases, conventional recanalization could not be successfully achieved. Results: The OUTBACK® catheter was used to recanalize 10 SFA occlusion and 9 CIA occlusions. In 19 patients (90%), reentry into true arterial lumen was successfully achieved. 17 patients had their recanalization through the transfemoral approach whereas 2 patients had a transpopliteal artery approach. In 2 patients, reentry into the true lumen could not be achieved using the OUTBACK® catheter due to patient's intolerability for the procedure and severe atherosclerotic calcified plaques. There was 100% patency of the vessel intervened on Duplex ultrasound at 24 months of follow up. 16 patients (84%) remained asymptomatic and 2 patients (10.5%) reported worsening of their symptoms due to the development of new lesions within the arterial system. Conclusion: The OUTBACK® catheter is an effective and safe technique for reentry into the vessel lumen when conventional techniques fail. PMID:27413275

    People admitted to intensive care units and those with chronic health care problems often require long-term vascular access. Central venous access devices (CVADs) are used for administering intravenous medications and blood sampling. CVADs are covered with a dressing and secured with an adhesive or adhesive tape to protect them from infection and reduce movement. Dressings are changed when they become soiled with blood or start to come away from the skin. Repeated removal and application of dressings can cause damage to the skin. The skin is an important barrier that protects the body against infection. Less frequent dressing changes may reduce skin damage, but it is unclear whether this practice affects the frequency of catheter-related infections. To assess the effect of the frequency of CVAD dressing changes on the incidence of catheter-related infections and other outcomes including pain and skin damage. In June 2015 we searched: The Cochrane Wounds Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We also searched clinical trials registries for registered trials. There were no restrictions with respect to language, date of publication or study setting. All randomised controlled trials (RCTs) evaluating the effect of the frequency of CVAD dressing changes on the incidence of catheter-related infections on all patients in any healthcare setting. We used standard Cochrane review methodology. Two review authors independently assessed studies for inclusion, performed risk of bias assessment and data extraction. We undertook meta-analysis where appropriate or otherwise synthesised data descriptively when heterogeneous. We included five RCTs (2277 participants) that compared different frequencies of CVAD dressing changes. The studies were all conducted in Europe and published between 1995 and 2009. Participants

    Introduction Peripherally inserted central venous catheters (PICCs) may adversely impact future successful arteriovenous fistulae (AVF). As part of a quality improvement project, the performance of tunneled small bore tunneled central venous catheters (TSB-CVCs), as alternatives to PICCs, was evaluated. Methods A retrospective observational study, involving individuals ≥18 years of age who underwent TSB-CVC placement by Interventional Radiology at Mayo Clinic, Rochester, MN between 1/1/2010 and 8/30/2013. Findings The study cohort included 92 patients with a median age of 55 (46-67) years, who underwent 108 TSB-CVC placements. Baseline renal disease was present in 71% (77/108). Most TSB-CVCs were placed in hospitalized patients (94%; 102/108); five French in diameter (61%; 66/108) and located in an internal jugular vein (84%; 91/108). Median catheter indwelling time was 20 (11-43) days (n = 84). TSB-CVC-related bloodstream infection, deep venous thrombosis (DVT), and superficial venous thrombosis (SpVT) rates per line were 0.009 (1/108), 0.018 (2/108), and 0.009 (1/108), respectively. Venous outcomes in a subgroup of 54 patients, who had documented PICC placements (n = 161) in addition to TSB-CVC (n = 58) were compared. TSB-CVC-DVT rate was lower than the PICC-DVT rate (0.017 [1/58] vs. 0.106 per line [17/161]; P = 0.04). The TSB-CVC-SpVT rate was not different from the PICC-SpVT rate (0 [0/58] vs. 0.037 [6/161] per line; P = 0.14). Discussion TSB-CVCs demonstrated an excellent safety profile in our study. These catheters should be preferentially utilized for arm vein preservation in advanced kidney disease. Their impact on future AVF success needs further evaluation.

    Most femoral artery arteriovenous fistulas occur as a result of percutaneous interventions. However, arteriovenous fistulas can occur in the setting of trauma, with resultant consequences such as heart failure, steal syndrome, or venous insufficiency. Indications for endovascular repair in this setting are limited to patients who are at too high risk for anesthesia, have a hostile groin, or would not survive significant bleeding. We report the case of a traumatic femoral arteriovenous fistula, causing severe venous insufficiency and arteriomegaly, in a 58-year-old male, with history of traumatic gunshot wound complicated by popliteal DVT. Surgical options for arteriovenous fistula include open and endovascular repair but this patient's fistula was more suitable for endovascular repair for reasons that will be discussed. PMID:28808595

    To compare the effect of 3 kinds of different materials on the hemostasis of puncture site after central venous catheterization. Method: A selection of 120 patients with peripheral central venous catheter chemotherapy in the Affiliated Hospital of our university from January 2014 to April 2015, Randomly divided into 3 groups, using the same specification (3.5cm × 2cm) alginate gelatin sponge and gauze dressing, 3 kinds of material compression puncture point, 3 groups of patients after puncture 24 h within the puncture point of local blood and the catheter after the catheter 72 h within the catheter maintenance costs. Result: (1) The local infiltration of the puncture point in the 24 h tube: The use of alginate dressing and gelatin sponge hemostatic effect is better than that of compression gauze. The difference was statistically significant (P <0.05). Compared with gelatin sponge and alginate dressing hemostatic effect, The difference was not statistically significant. (2) Tube maintenance cost: Puncture point using gelatin sponge, The local maintenance costs of the catheter within 72 h after insertion of the tube are lowest, compared with alginate dressing and gauze was significant (P<0.05). Conclusion: The choice of compression hemostasis material for the puncture site after PICC implantation, using gelatin sponge and gauze dressing is more effective and economic.

    Direct measurement of venous length is easy to cause contamination during bedside insertion of peripherally inserted central venous catheter (PICC). It is necessary to provide an equation for proper estimate of catheter length in case of bedside insertion of PICC in relation to patient height. For 165 PICC cases through left arm vein in 151 adult patients (male: female = 72:79), the cubital crease to carina length (CCL) was calculated as follows: CCL = (distance from cubital crease to puncture point) + (length of PICC inside body) - (distance from carina to catheter tip on post-procedural chest radiograph). We analyzed the relationship between CCL and height with regression analysis and suggest a new equation of CCL based on height. The mean CCL through the left arm vein was 47.1 ± 2.6 cm in male and 44.0 ± 2.9 cm in female. CCL was significantly correlated with patient height. Equation of CCL (cm) based on height was as follows: CCL = height * 0.19 + 14. The equation of our study would provide a new equation for proper estimation of catheter length in case of bedside insertion of left arm PICC in relation to height and be helpful for optimal positioning of catheter tip of PICC.

    Central venous catheters (CVC) are frequently used in intensive care units (ICU), with a low incidence of complications, most of them being of mechanical origin and occurring during the insertion of the catheter. To avoid such complications, "ultrasound guidance" and "ultrasound assistance" are recommended. Nevertheless, even with trained and experienced physicians, mechanical complications of IJV access such as carotid punctures are still reported. We report the case of a 75-year-old woman, admitted into the ICU for CVC insertion due to impossibility of peripheral venous access. About 12 hours after the procedure, the patient presented a neurological deficit. The cervical and thoracic CT scan showed a transfixing path of the catheter from the left IJV into the left common carotid artery, with distal extremity of the catheter localized in the ascending aorta. The catheter was removed, and thereafter the neurological deficit immediately and definitely disappeared. Onset of a neurological deficit after CVC insertion into the IJV, regardless the time of occurrence after the procedure, should suggest complication due to the CVC insertion, even if procedure was uneventful and chest radiography confirmed the apparent accurate position of CVC.

    To determine whether a bacteriophage antimicrobial-lock technique can reduce bacterial colonization and biofilm formation on indwelling central venous catheters in a rabbit model. Cuffed central venous catheters were inserted into the jugular vein of female New Zealand White rabbits under image guidance. Catheters were inoculated for 24 hours with broth culture of methicillin-sensitive Staphylococcus aureus. The inoculum was aspirated, and rabbits were randomly assigned to two equal groups for 24 hours: (i) untreated controls (heparinized saline lock), (ii) bacteriophage antimicrobial-lock (staphylococcal bacteriophage K, propagated titer > 10(8)/mL). Blood cultures were obtained via peripheral veins, and the catheters were removed for quantitative culture and scanning electron microscopy. Mean colony-forming units (CFU) per cm(2) of the distal catheter segment, as a measure of biofilm, were significantly decreased in experimental animals compared with controls (control, 1.2 × 10(5) CFU/cm(2); experimental, 7.6 × 10(3); P = .016). Scanning electron microscopy demonstrated that biofilms were present on the surface of five of five control catheters but only one of five treated catheters (P = .048). Blood culture results were not significantly different between the groups. In a rabbit model, treatment of infected central venous catheters with a bacteriophage antimicrobial-lock technique significantly reduced bacterial colonization and biofilm presence. Our data represent a preliminary step toward use of bacteriophage therapy for prevention and treatment of central venous catheter-associated infection. Copyright © 2014 SIR. All rights reserved.

Am J Physiol Heart Circ Physiol 288: H2995–H3000, 2005; doi:10.1152/ajpheart.00703.2004.—The purpose of this study is to evaluate the feasibility of percutaneous antegrade myocardial gene transfer (PAMGT). A consistent and safe technique for in vivo gene transfer is required for clinical application of myocardial gene therapy. PAMGT with concomitant coronary venous blockade was performed in 12 swine. The myocardium was preconditioned with 1 min of occlusion of the left anterior descending and left circumflex arteries. The anterior interventricular vein was occluded during left anterior descending artery delivery, and the great cardiac vein at the entrance of the middle cardiac vein was occluded during left circumflex artery delivery. With arterial and venous balloons inflated (3 min) and after adenosine (25 μg) injection, PAMGT was performed by antegrade injection of an adenoviral solution (1 ml of 1011 plaque-forming units in each coronary artery) carrying β-galactosidase or saline through the center lumen of the angioplasty balloon. In one set of animals, PAMGT was performed with selective coronary vein blockade (n = 9); in another set of animals, PAMGT was performed without coronary vein blockade (n = 5). At 1 wk after gene delivery, the animals were killed. Quantitative β-galactosidase analysis was performed in the left and right ventricular walls. PAMGT was successfully performed in all animals with and without concomitant occlusion of the coronary veins. Quantitative β-galactosidase analysis showed that PAMGT with coronary blockade was superior to PAMGT without coronary blockade. β-Galactosidase activity increased significantly in the

    Treatment for most children with cancer includes the use of a central venous catheter (CVC). CVCs provide reliable venous access for delivery of chemotherapy and supportive care. This advantage is mitigated by an increased risk of bloodstream infections (BSIs). Despite the ubiquitous use of CVCs, few prospective studies have been conducted to address infection prevention strategies in pediatric oncology patients. Prospective, crossover pilot study of a CVC team intervention versus standard care. Two inpatient oncology units in a metropolitan children's hospital. A total of 41 patients/135 admissions for the experimental unit (EU) and 41/129 admissions for the control unit (CU). Patients received a CVC blood draw bundle procedure by a CVC registered nurse (RN) team member (experimental intervention: EU) for 6 months and by the assigned bedside RN (standard care: CU) for 6 months. Feasibility of implementing a CVC RN team; a significant difference in CVC-related BSIs between the team intervention versus standard care and risk factors associated in the development of CVC-related BSIs were determined. There were 7 CVC-related BSIs/1238 catheter days in the EU group (5.7/1000 catheter days) versus 3 CVC-related BSIs/1419 catheter days in the CU group (2.1/1000 catheter days; P = .97). Selected risk factors were not significantly associated with the development of a CVC-related BSI. A CVC team in the care of pediatric oncology patients is feasible; however, a larger cohort will be required to adequately determine the effectiveness of the team reducing CVC-related BSIs.

    Hemostasis at the femoral venous access site after atrial fibrillation (AF) ablation is often prolonged because of aggressive anticoagulation and the use of several large-sized sheaths. A newly developed hemostatic pad containing a natural mineral called kaolin causes blood to clot quickly. We evaluated the efficacy of this pad for hemostasis at the venous access site after AF ablation. Patients who were scheduled to undergo AF ablation were randomized to be treated with manual compression with (n = 59) or without kaolin-impregnated pads (n = 59) as hemostatic approaches at the femoral venous access site following sheath removal. Hemostasis time, rebleeding frequency, massive hematoma, device-related complications, and deep venous thrombosis (DVT) were compared between the two groups. Hemostasis time in the patients treated with kaolin-impregnated pads was significantly shorter than in those treated without (6.1 ± 2.3 vs. 14.5 ± 4.0 min; p < 0.0001). Multiple linear regression analysis revealed that the use of kaolin-impregnated pads was the only independent variable reducing hemostasis time (β = -0.78; p < 0.0001). However, rebleeding rates of the two groups were similar (37% with vs. 46% without kaolin-impregnated pads; p = 0.35). Only one patient had a massive groin hematoma, and no patient had device-related complications or DVT. Kaolin-impregnated hemostatic pads safely and effectively decreased hemostasis time for the femoral venous access site in patients undergoing AF ablation. However, whether its use allows earlier postprocedural ambulation is difficult to predict.

    This report describes a technique of inserting an implantable venous access port (portacath) through a thrombosed and occluded vein employing a pre-existing peripherally inserted central catheter (PICC) as the route of access. The PICC was used as a conduit for venous access in a way that has not been described previously in the literature. This procedure was performed in a young patient with cystic fibrosis in an effort to prevent the use of his virgin contralateral veins, which might be used in the future.

    To evaluate variations of pulmonary venous drainage and venous ostium index (VOI) in patients with atrial fibrillation (AF) prior to radio-frequency catheter ablation (RFCA) by MDCT pulmonary venography. 16-detector row CT pulmonary venography was performed in 64 AF patients referred to RFCA from June, 2005 to May, 2006. Variations in pulmonary venous drainage were observed in volume render imagines. Anterior-posterior and superior-inferior diameters of pulmonary venous ostium were measured on maximum intensity projection images. VOI derived from left superior, left inferior, right superior, right inferior pulmonary veins and variations in pulmonary venous drainage were calculated. Classic pulmonary veins anatomy was found in 11 patients (17.18%), early branching veins in 45 patients (70.31%), left common ostium in 5 patients (7.81%), right common ostia in 1 patient, right accessory (middle) pulmonary vein in 5 patients (7.81%) and left accessory (middle) pulmonary vein in 1 patient (1.56%). VOI of homolateral pulmonary veins and bilateral superior pulmonary veins were similar (P > 0.05) while there was a significant difference on VOIs derived from left superior and right inferior; two inferior, left inferior versus right superior veins (P < 0.05). Right inferior pulmonary venous ostium was most rounded and had the highest index (0.88) and left inferior pulmonary venous ostium was most oval and had the lowest index (0.72). Multidetector row CT pulmonary venography (MDCT-PV) could provide valuable informations on pulmonary venous anatomy in AF patients referred to RFCA and should be used as a routine examination prior to the operation.

    To describe the incidence and risk factors of venous thromboembolism in a large sample of critical care pediatric, adolescent, and young adult trauma patients. The National Trauma Data Bank-the largest and most complete aggregation of trauma registry data in the United States. Seven hundred eighty-four level I to level IV trauma centers. Patients ≤ 21 yrs of age who spent at least 1 day in a critical care unit during a trauma admission between 2001 and 2005. To characterize differences between patients with and without venous thromboembolism, we extracted variables regarding patient demographics, injury pattern and severity, procedures, total length of stay, and intensive care unit and ventilator days. Odds ratios for predictors of venous thromboembolism were estimated with a logistic regression model. Among the 135,032 critical care patients analyzed, venous thromboembolism was uncommon (6 per 1,000 discharges). Placement of a central venous catheter was a significant predictor of venous thromboembolism (odds ratio = 2.24; p < .0001) when populations were analyzed collectively. When we narrowed our focus to injuries associated with venous thromboembolism, such as lower-extremity fractures, the effects of central venous catheter were of even greater magnitude, particularly in adolescents and young adults. The risk of venous thromboembolism in critical care patients without a central venous catheter was <1% even in adolescents/young adults. Venous thromboembolism is rare in young critical care trauma patients, even older adolescents. The absence of published data on both the baseline risk of venous thromboembolism in pediatric critical care patients and the efficacy and safety of venous thromboembolism prophylaxis preclude the ability to make definitive recommendations for the use of venous thromboembolism prophylaxis in this setting. Our results, however, suggest that venous thromboembolism prophylaxis may need to be considered only in critically injured

    Objective: To evaluate the efficacy and safety of the treatment of traumatic hemothorax by closed pleural drainage using a central venous catheter (CVC), compared with using a conventional chest tube. Methods: A prospective controlled study with the Ethics Committee approval was undertaken. A total of 407 patients with traumatic hemothorax were involved and they were randomly assigned to undergo closed pleural drainage with CVCs (n=214) or conventional chest tubes (n=193). The Seldinger technique was used for drainage by CVC, and the conventional technique for drainage by chest tube. If the residual volume of the hemothorax was less than 200 ml after the daily volume of drainage decreased to below 100 ml for two consecutive days, the treatment was considered successful. The correlative data of efficacy and safety between the two groups were analyzed using t or chi-squared tests with SPSS 13.0. A P value of less than 0.05 was taken as indicating statistical significance. Results: Compared with the chest tube group, the operation time, fraction of analgesic treatment, time of surgical wound healing, and infection rate of surgical wounds were significantly decreased (P<0.05) in the CVC group. There were no significant differences between the two groups in the success rate of treatment and the incidence of serious complications (P>0.05), or in the mean catheter/tube indwelling time and mean medical costs of patients treated successfully (P>0.05). Conclusions: Management of medium or large traumatic hemothoraxes by closed thoracic drainage using CVC is minimally invasive and as effective as using a conventional large-bore chest tube. Its complications can be prevented and it has the potential to replace the large-bore chest tube. PMID:22205619

    Central venous catheters (CVCs) are commonly used for the administration of intravenous chemotherapy in outpatient setting. Nevertheless, outbreaks of catheter-associated bloodstream infections had been reported from oncology centers. We describe a large outbreak of CVCs-associated Klebsiella oxytoca bloodstream infection, occurring in an oncology chemotherapy outpatient unit of northern Greece between October 2006 and May 2007. The outbreak involved approximately 10% of the patients with CVCs who were receiving home-based chemotherapy, and it represents the second larger outbreak of CVCs-associated BSIs due to Klebsiella oxytoca in oncology outpatient centers. We retrospectively analyzed the chain of investigations and prophylactic/diagnostic measures taken to eradicate the infection: (1) patients' chart audit, (2) estimation of the infection among asymptomatic patients, (3) implementation of the level of awareness of medical and paramedical personnel, (4) collection of samples from environment, medications and infusion materials, (5) critical appraisal of chemotherapeutical schemes and (6) cooperation with peripheral institutions. The isolation of Klebsiella oxytoca in a chemotherapy solution (infusional 5-FU in dextrose 5% solution within a 48 h pump) from a peripheral General Hospital and the prompt transmission of the data to the chemotherapy center played a key role for the management of the infection cluster. This is the first report that evidenced the detection of Klebsiella oxytoca within a chemotherapeutical preparation. Data transmission from peripheral hospitals to the central institution resulted in an important feedback that allowed a better estimation of the infection cluster and more tailored actions for the eradication of the infection.

    Adherent bacteria and biofilm frequently colonize central venous catheters (CVCs). CVC colonization is correlated to infections and particularly to bloodstream ones. The classical microbiological methods to determine of CVC colonization are not fully reliable and are time-consuming. BioTimer Assay (BTA) is a biological method already used to count bacteria adherent to abiotic surfaces and biofilm without sample manipulation. BTA employs specific reagents whose color changed according to bacterial metabolism. BTA is based on the principle that a metabolic reaction will be faster when more bacteria are present in the sample. Therefore, the time required for color changes of BTA reagents determines the number of bacteria present in the sample through a correlation line. Here, for the first time, we applied BTA and a specifically developed laboratory procedure to evaluate CVC colonization in comparison with the routine microbiological method (RMM). 125 CVCs removed from patients for suspected catheter-related bloodstream infection (CRBSI) or at hospital discharge were examined. BTA was reliable in assessing sterility and CVC colonization (100% agreement with RMM) and in recognizing the presence of fermenting or non-fermenting bacteria (97.1% agreement with RMM) shortening the analytical time by between 2- and 3-fold. Moreover, the reliability of BTA as early alert of CRBSI was evaluated. The sensitivity, specificity, positive, and negative predictive values for BTA as an early alert of CRBSI were 100, 40.0, 88.8 and 100%, respectively. In conclusion, BTA and the related laboratory procedure should be incorporated into routine microbiological methods since it can be considered a reliable tool to evaluate CVC colonization in a very short time and a rapid alert for CRBSIs.

    Aim The objective of this study was to critically analyze data of the National Notification System for Adverse Events and Technical Complaints (Notivisa) related to central venous catheters, through an evaluation of the description of notifications recorded between 2006 and 2009. Methods Notifications were categorized and evaluated to: (i) determine the number of adverse events and technical complaints, (ii) verify compliance with the classification criteria defined by the legislation, (iii) reclassify notifications, when necessary, in order for them to fit in with the legal definitions, (iv) verify registered companies in Brazil, (v) quantify the notifications according to the registered company and product lot, and (vi) identify the country of original of the notified product. Microsoft Excel(r) 2010 was used to categorize and systematize the data. Results Some conceptual errors and incomplete records were found. Altogether, 228 notifications of technical complaints and 119 of adverse events were identified. Some notifications on guidewires and broken catheters were reported which led to the necessity of duplicating some medical procedures and to the occurrence of lesions/lacerations of vessels and tissue injury. Forty-seven percent of companies presented at least one notification in Notivisa and in all, 38 product lots had more than one notification. Conclusion These data support a necessity for cooperation between all entities of the National Health Surveillance System to check compliance of this type of product and to properly report adverse events and technical complaints. It is also important to incorporate minimum standards for the management of technologies in health services, including in the acquisition of products and training of staff. PMID:23904810

    Infection of the central venous catheter (CVC) is the main aggravating factor of parenteral nutrition. The aim of this study was to determine the ecology of these infections in our home parenteral nutrition center and to evaluate our care protocol. The present study was monocentric and retrospective, and was conducted in the parenteral nutrition service of the Marseille University Hospital between 1 January 2011 and 31 May 2012. During this period, all the children who presented fever and a positive hemoculture in a medical emergency were taken into account, and the characteristics of the infection were analyzed. After 17 months, 17 children had been subject to an infection in their central catheter: 47 bacteremia were identified, which is equivalent to 5.4 infections for 1000 days of CVC. An average 2.8 hemocultures were performed during this time. The most common bacterium was Staphylococcus hominis. The children affected by a digestive stoma or by a gastrostomy were not subject to more infections and their ecology was not different. All the children were referred to the hospital and treated with an intravenous antibiotic through the CVC. As expected during the time of the study, the infection rate was very high. This finding led us to reassess our prevention protocol. It is also very likely that the number of infections was overestimated due to the protocol for sampling in the hemocultures and their subsequent analysis. Lastly, some children relapsed easily, although no predisposing factor was found in the present study. The therapy chosen was in agreement with the best practices and the ecology recovered. The high number of infections observed during the study encourages a prospective evaluation of current practices. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    The use of peripheral venous catheters (PVCs) has increased outside intensive care units, as has the rate of PVC-associated-bloodstream infection (PVC-BSI). PVCs are widely used in internal medicine departments (IMDs), but data on the incidence of PVC-BSI and its characteristics in IMDs are scarce. To assess the incidence of PVC-BSI episodes detected in IMDs in Spain. A one-year multi-centre prospective observational cohort study in 14 Spanish IMDs was undertaken. Adult patients admitted with at least one PVC and bacteraemia were included in the study. Demographic and clinical data were provided by local coordinators. Seventy episodes of PVC-BSI were recorded, representing an overall rate of 1.64 PVC-BSI episodes/1000 IMD admissions. The mean age of patients was 67.44 (standard deviation 16.72) years. It was estimated that 25.7% of PVCs were no longer necessary. Staphylococcus aureus was the most frequently isolated micro-organism (41.7%). Phlebitis was clinically evident in 44 (62.9%) episodes, and proved to be an independent predictor of catheter insertion in emergency departments (odds ratio 5.44). The crude and attributable mortality rates were 12.9% and 5.7%, respectively. PVCs carry a significant risk for bacteraemia in Spanish IMDs. Phlebitis is not always clinically evident in patients with bacteraemia in this population. The study findings support the need for educational and interventional preventive measures in both IMDs and emergency departments to reduce the rate of PVC-BSI and associated comorbidities, and costs.

  11. Convective Leakage Makes Heparin Locking of Central Venous Catheters Ineffective within Seconds: Experimental Measurements in a Model Superior Vena Cava

    Central venous catheters (CVCs), placed in the Superior Vena Cava (SVC) for hemodialysis or chemotherapy, are routinely filled while not in use with heparin, an anticoagulant, to maintain patency and prevent thrombus formation at the catheter tip. The heparin-locking procedure, however, places the patient at risk for systemic bleeding, as heparin is known to leak from the catheter into the blood stream. We provide evidence from detailed in-vitro experiments that shows the driving mechanism behind heparin leakage to be convective-diffusive transport due to the pulsatile flow surrounding the catheter. This novel mechanism is supported by experimental planar laser induced fluorescence (PLIF) and particle image velocimetry (PIV) measurements of flow velocity and heparin transport from a CVC placed inside a model SVC inside a pulsatile flow loop. The results predict an initial, fast (< 10s), convection-dominated phase that rapidly depletes the concentration of heparin in the near-tip region, the region of the catheter with side holes. This is followed by a slow, diffusion-limited phase inside the catheter lumen, where the concentration is still high, that is insufficient at replenishing the lost heparin concentration in the near-tip region. The results presented here, which are consistent with previous in vivo estimates of 24-hour leakage rates, predict that the concentration of heparin in the near-tip region is essentially zero for the majority of the interdialytic phase, rendering the heparin locking procedure ineffective.

    A preliminary observational study was undertaken to evaluate the risk of failure of ultrasound-guided peripheral intravenous catheterization of a deep arm vein for a maximum of 7 days, after peripheral intravenous (PIV) cannulation failure. This prospective study included patients referred to the intensive care unit for placement of a central line, a polyurethane cannula commercialized for arterial catheterization was used for peripheral venous cannulation. Catheter length and diameter were chosen based on preliminary ultrasound measurements of vein diameter and skin-vein distance. Catheterization was successful for all 29 patients. Mean vein diameter was 0.42 ± 0.39 cm; mean vein depth was 0.94 ± 0.52 cm. Mean catheter duration was 6 (median 7) days. Two occluded catheters were removed prematurely. No thrombophlebitis, catheter infection, or extravasation was observed. Our results suggest that catheters inserted with the Seldinger method are adapted to prolonged peripheral deep-vein infusion. Ultrasound can play a role in catheter monitoring by identifying early thrombosis formation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Central venous port devices made of two different polymeric materials, thermoplastic polyurethane (TPU) and silicone rubber (SiR), were compared due their material properties. Both naïve catheters as well as catheters after removal from patients were investigated. In lab experiments the influence of various chemo-therapeutic solutions on material properties was investigated, whereas the samples after removal were compared according to the implanted time in patient. The macroscopic, mechanical performance was assessed with dynamic, specially adapted tests for elasticity. The degradation status of the materials was determined with common tools of polymer characterisation, such as infrared spectroscopy, molecular weight measurements and various methods of thermal analysis. The surface morphology was analysed using scanning electron microscopy. A correlation between material properties and clinical performance was proposed. The surface morphology and chemical composition of the polyurethane catheter materials can potentially result in increased susceptibility of the catheter to bloodstream infections and thrombotic complications. The higher mechanic failure, especially with increasing implantation time of the silicone catheters is related to the lower mechanical performance compared to the polyurethane material as well as loss of barium sulphate filler particles near the surface of the catheter. This results in preformed microscopic notches, which act as predetermined sites of fracture.

    Purpose Long-term central venous catheters (CVCs) are often used in patients with cancer to facilitate venous access to administer intravenous fluids and chemotherapy. CVCs can also be a source of bloodstream infections, although this risk is not well understood. We examined the impact of long-term CVC use on infection risk, independent of other risk factors such as chemotherapy, in a population-based cohort of patients with cancer. Patients and Methods We conducted a retrospective analysis using SEER-Medicare data for patients age > 65 years diagnosed from 2005 to 2007 with invasive colorectal, head and neck, lung, or pancreatic cancer, non-Hodgkin lymphoma, or invasive or noninvasive breast cancer. Cox proportional hazards regression was used to examine the relationship between CVC use and infections, with CVC exposure as a time-dependent predictor. We used multivariable analysis and propensity score methods to control for patient characteristics. Results CVC exposure was associated with a significantly elevated infection risk, adjusting for demographic and disease characteristics. For patients with pancreatic cancer, risk of infections during the exposure period was three-fold greater (adjusted hazard ratio [AHR], 2.93; 95% CI, 2.58 to 3.33); for those with breast cancer, it was six-fold greater (AHR, 6.19; 95% CI, 5.42 to 7.07). Findings were similar when we accounted for propensity to receive a CVC and limited the cohort to individuals at high risk of infections. Conclusion Long-term CVC use was associated with an increased risk of infections for older adults with cancer. Careful assessment of the need for long-term CVCs and targeted strategies for reducing infections are critical to improving cancer care quality. PMID:24982458

    The incidence of deep venous thrombosis (DVT) related to a central venous catheter varies considerably in ICUs depending on the population included. The aim of this study was to determine subclavian central venous catheter (SCVC)-related DVT risk factors in severely traumatized patients with regard to two kinds of polyurethane catheters. Critically ill trauma patients needing a SCVC for their usual care were prospectively included in an observational study. Depending on the month of inclusion, patients received one of the two available products in the emergency unit: either an aromatic polyurethane SCVC or an aliphatic polyurethane SCVC. Patients were screened weekly by ultrasound for SCVC-related DVT. Potential risk factors were collected, including history-related, trauma-related and SCVC-related characteristics. A total of 186 patients were included with a median Injury Severity Sore of 30 and a high rate of severe brain injuries (21% of high intracranial pressure). Incidence of SCVC-related DVT was 37% (95% confidence interval: 26 to 40) in patients or 20/1,000 catheter-days. SCVC-related DVT occurred within 8 days in 65% of cases. There was no significant difference in DVT rates between the aromatic polyurethane and aliphatic polyurethane SCVC groups (38% vs. 36%). SCVC-related DVT independent risk factors were age>30 years, intracranial hypertension, massive transfusion (>10 packed red blood cell units), SCVC tip position in the internal jugular or in the innominate vein, and ipsilateral jugular catheter. SCVC-related DVT concerned one-third of these severely traumatized patients and was mostly clinically silent. Incidence did not depend on the type of polyurethane but was related to age>30 years, intracranial hypertension or misplacement of the SCVC. Further studies are needed to assess the cost-effectiveness of routine screening in these patients in whom thromboprophylaxis may be hazardous.

  18. In vitro evaluation of a micro-Doppler catheter for detection and aspiration of venous air emboli.

    Venous air embolism (VAE) is a potentially fatal complication of surgery when open veins at a surgical site are exposed to ambient air pressure which exceeds the pressure in the venous system. Common techniques of detecting VAE are precordial Doppler monitoring and transesophogeal echocardiography. Precordial Doppler monitoring has poor accuracy and transesophogeal echocardiography is expensive and user-intensive. In both methods, a separate catheter must be inserted into the vena cava so that an embolus may be aspirated if it is detected. We created a micro-Doppler assembly using two ceramic transducers fitted over a 5.8F multiorifice central venous catheter. This micro-Doppler catheter (MDC) was tested in vitro using a static tank and an artificial vena cava (AVC). The MDC was also tested for acoustic pressure and current leakage in the static tank and for heat generation and cavitation in the AVC. The MDC was able to detect bubbles more than 2 mm in diameter with 100% accuracy. A blinded observer was able to identify the onset of vapor lock in 10 of 10 trials. The same observer was able to terminate vapor lock in 10 of 10 trials. The acoustic pressures measured were <1.8 MPa. There was no increase in temperature in the AVC over 24 h and there was no evidence of cavitation in the AVC over 4 h. We have created a MDC that can detect air emboli and relieve vapor lock in a simulated vena cava and atrium. This catheter could be placed percutaneously in the vena cava. Based on the measurements of acoustic pressure, temperature in the AVC and lack of cavitation in the AVC, the device appears to be safe for use in humans. More studies are required to determine if the catheter could be used to detect and aspirate VAE during surgeries where VAE is likely, such as sitting craniotomy.

    Cuffed tunneled venous access catheters are commonly used for temporary and permanent access in hemodialysis (HD) patients. These catheters serve an essential role in providing permanent access in subjects in whom all other access options have been exhausted. The predominant complications are catheter thrombosis, catheter fibrin sheating and infection. The aim of this study was to evaluate long-term survival and complications of permanent venous catheters (PVC) placed for the purpose of HD during the period from January 1992 to December 1998, at the Dialysis Units of Lucania (a southern Italian region). A total of 98 PVC were placed in 88 patients during this period. The catheters used were of three types: (a) 72 VasCath Soft Cell catheters (Bard Instrument Company, Toronto, Ont., Canada); (b) 22 PermCath catheters (Quinton Instrument Company, Seattle, Wash., USA), and (c) 4 Tesio catheters (Bellco SpA, Mirandola, Italy). Survival curves of catheters were calculated using the Kaplan-Meier product-limit estimator. The patient survival was 60% at the 78th month. Actually, 52 patients (27 males, 25 females) are still alive: 15 (26.9%) of these patients have diabetes mellitus and 1 has been transplanted. The actuarial survival rate of PVC was 89% in the whole population studied and 82% in subjects alive after 84 months. Twenty-five patients (28.4%) had PVC as the first reliable vascular access. Long-term complications occurred 27 times (1 episode every 44.81 month/patient) as: breakage (3.1%); thrombosis (10.2%); displacement (2.0%); subcutaneous tunnel bleeding (3.1%); inadequate blood flow (7.1%), and infection (10.2%). In conclusion, our data confirm that PVC might represent an effective long-term blood access route for HD. Again, PVC are getting the access of choice for selected patients (i.e., older subjects with cardiovascular diseases and cancer patients) and are enjoying a dramatic increase in use for subjects who are terrified of repetitive venopuncture.

    Central venous catheters are commonly used in the management of critically ill patients. Their insertion can be challenging in hemodynamically unstable patients and in those with altered thoracic anatomy. Although ultrasound guided insertion can reduce this problem, this facility may not be available in all locations and in all institutions. Accidental arterial puncture is one of the very serious complications that can occur during central venous catheter insertion. This is usually detected clinically by bright color and projectile/pulsatile flow of the returning blood. However, such means are known to be misleading especially in hypoxic and hemodynamically unstable patients. Other recognized measures used to identify arterial puncture would be blood gas analysis of the returning blood, use of pressure transducer to identify waveform pattern and the pressures. In this article, we propose that trachea and carina can be used as a reliable radiological landmark to identify accidental arterial placement of central venous catheters. We further conclude that this information could be useful especially when dealing with post-resuscitation victims and hemodynamically unstable critically ill patients.

  1. Skin Necrosis after a Low-Dose Vasopressin Infusion through a Central Venous Catheter for Treating Septic Shock

    This is a report on a case of severe skin necrosis in a vasodilatory septic shock patient after the infusion of low-dose vasopressin through a central venous catheter. An 84-year-old male was hospitalized for edema on both legs at Asan Medical Center, Seoul, Korea. On hospital day 8, the patient began to complain of dyspnea and he subsequently developed severe septic shock caused by E. coli. After being transferred to the medical intensive care unit, his hypotension, which was refractory to norepinephrine, was controlled by an infusion of low-dose vasopressin (0.02 unit/min) through a central venous catheter into the right subclavian vein. After the infusion of low-dose vasopressin, severe skin necrosis with bullous changes developed, necessitating discontinuation of the low-dose vasopressin infusion. The patient expired from refractory septic shock. Although low-dose vasopressin can control hypotension in septic shock patients, low-dose vasopressin must be used with caution because ischemic complications such as skin necrosis can develop even with administration through a central venous catheter.

    A peripheral venous catheter (PVC) is typically used for short-term delivery of intravascular fluids and medications. It is an essential element of modern medicine and the most frequent invasive procedure performed in hospitals. However, PVCs often fail before intravenous treatment is completed: this can occur because the device is not adequately attached to the skin, allowing the PVC to fall out, leading to complications such as phlebitis (irritation or inflammation to the vein wall), infiltration (fluid leaking into surrounding tissues) or occlusion (blockage). An inadequately secured PVC also increases the risk of catheter-related bloodstream infection (CRBSI), as the pistoning action (moving back and forth in the vein) of the catheter can allow migration of organisms along the catheter and into the bloodstream. Despite the many dressings and securement devices available, the impact of different securement techniques for increasing PVC dwell time is still unclear; there is a need to provide guidance for clinicians by reviewing current studies systematically. To assess the effects of PVC dressings and securement devices on the incidence of PVC failure. We searched the following electronic databases to identify reports of relevant randomised controlled trials (RCTs): the Cochrane Wounds Group Register (searched 08 April 2015): The Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 3), Ovid MEDLINE (1946 to March 7 2015); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, March 7 2015); Ovid EMBASE (1974 to March 7 2015); and EBSCO CINAHL (1982 to March 8 2015). RCTs or cluster RCTs comparing different dressings or securement devices for the stabilisation of PVCs. Cross-over trials were ineligible for inclusion, unless data for the first treatment period could be obtained. Two review authors independently selected studies, assessed trial quality and extracted data. We contacted study authors for missing information. We used standard

    Background Catheters are the most common cause of nosocomial infections and are associated with increased risk of mortality, length of hospital stay and cost. Prevention of infections and fast and correct diagnosis is highly important. Methods In this study traditional semiquantitative culture-dependent methods for diagnosis of bacteria involved in central venous catheter-related infections as described by Maki were compared with the following culture-independent molecular biological methods: Clone libraries, denaturant gradient gel electrophoresis, phylogeny and fluorescence in situ hybridization. Results In accordance with previous studies, the cultivation of central venous catheters from 18 patients revealed that S. epidermidis and other coagulase-negative staphylococci were most abundant and that a few other microorganisms such as P. aeruginosa and K. pneumoniae occasionally were found on the catheters. The molecular analysis using clone libraries and sequencing, denaturant gradient gel electrophoresis and sequencing provided several important results. The species found by cultivation were confirmed by molecular methods. However, many other bacteria belonging to the phyla Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes were also found, stressing that only a minor portion of the species present were found by cultivation. Some of these bacteria are known to be pathogens, some have not before been described in relation to human health, and some were not closely related to known pathogens and may represent new pathogenic species. Furthermore, there was a clear difference between the bacterial species found in biofilm on the external (exluminal) and internal (luminal) side of the central venous catheter, which can not be detected by Maki's method. Polymicrobial biofilms were observed on most of the catheters and were much more common than the cultivation-dependent methods indicated. Conclusion The results show that diagnosis based on molecular methods

    Peripherally inserted central venous catheters (PICC) have been successfully used to provide central access for chemotherapy and frequent transfusions. The purpose of this study was to assess the feasibility of PICCs and determine PICC-related complications in pediatric hematology/oncology patients in a resource-poor setting. All pediatric patients (age below 16 y) with hematologic and malignant disorders who underwent PICC line insertion at Aga Khan University Hospital from January 2008 to June 2010 were enrolled in the study. Demographic features, primary diagnosis, catheter days, complications, and reasons for removal of device were recorded. Total of 36 PICC lines were inserted in 32 pediatric patients. Complication rate of 5.29/1000 catheter days was recorded. Our study showed comparable complication profile such as infection rate, occlusion, breakage, and dislodgement. The median catheter life was found to be 69 days. We conclude that PICC lines are feasible in a resource-poor setting and recommend its use for chemotherapy administration and prolonged venous access.

    Totally implanted venous access ports (TIVAPs) are commonly used catheters for the management of acute or chronic pathologies. Although these devices improve health care, repeated use of this type of device for venous access over long periods of time is also associated with risk of colonization and infection by pathogenic bacteria, often originating from skin. However, although the skin microbiota is composed of both pathogenic and nonpathogenic bacteria, the extent and the consequences of TIVAP colonization by nonpathogenic bacteria have rarely been studied. Here, we used culture-dependent and 16S rRNA gene-based culture-independent approaches to identify differences in bacterial colonization of TIVAPs obtained from two French hospitals. To explore the relationships between nonpathogenic organisms colonizing TIVAPs and the potential risk of infection, we analyzed the bacterial community parameters between TIVAPs suspected (symptomatic) or not (asymptomatic) of infection. Although we did not find a particular species assemblage or community marker to distinguish infection risk on an individual sample level, we identified differences in bacterial community composition, diversity, and structure between clinically symptomatic and asymptomatic TIVAPs that could be explored further. This study therefore provides a new view of bacterial communities and colonization patterns in intravascular TIVAPs and suggests that microbial ecology approaches could improve our understanding of device-associated infections and could be a prognostic tool to monitor the evolution of bacterial communities in implants and their potential susceptibility to infections. IMPORTANCE Totally implanted venous access ports (TIVAPs) are commonly used implants for the management of acute or chronic pathologies. Although their use improves the patient's health care and quality of life, they are associated with a risk of infection and subsequent clinical complications, often leading to implant removal

    This multi-centre prospective field study evaluated whether peripheral venous catheter site of insertion influences the risk of catheter-related phlebitis. Potential predictors of phlebitis were also investigated. Millions of patients worldwide use peripheral venous catheters, which frequently cause local complications including phlebitis, infection and obstruction. Although phlebitis predictors have been broadly investigated, uncertainties remain on the potential effect of cannulation anatomical site, duration and the appropriate time for catheter removal. A prospective cohort design was carried out from January-June 2012. The clinical course of each patient who received a new peripheral venous catheter for any cause in five Italian hospitals was followed by trained nurses until catheter removal. The presence of phlebitis was assessed every 24 hours using the Visual Infusion Phlebitis score. Analyses were based upon multilevel mixed-effects regression. The final sample consisted of 1498 patients. The average time for catheters in situ was 65·6 hours and 23·6% of the catheters were in place beyond 96 hours. Overall phlebitis incidence was 15·4%, 94·4% of which were grade 1. The likelihood of phlebitis independently increased with increasing catheter duration, being highest after 96 hours. Compared with patients with catheter placed in the dorsum of the hand (22·8% of the sample), those with the catheter located in the antecubital fossa (34·1%) or forearm were less likely to have a phlebitis of any grade. Antecubital fossa and forearm veins may be preferential sites for peripheral venous cannulation. Our results support Centers for Disease Control and Prevention recommendations to replace catheters in adults no later than 96 hours. A relevant proportion of healthcare personnel did not adhere to such guidelines - more attention to this issue is required. © 2014 John Wiley & Sons Ltd.

  8. Factors affecting survival in pediatric cardiac tamponade caused by central venous catheters.

    Pediatric central venous catheter (CVC) placement is useful but associated with complications such as cardiac tamponade. We aimed to identify risk factors for death in cardiac tamponade. Published articles on pediatric CVC-associated cardiac tamponade were obtained by searching PubMed and Google and retrospectively reviewed to analyze risk factors for death. Factors examined for their effect on mortality risk included patient age, weight, CVC size, days from CVC insertion to tamponade occurrence, substances administered, insertion site, treatment, CVC material, and initial CVC tip position. Of 110 patients reported in 62 articles, 69 survived and 41 died. Among survivors, 55 of 69 patients were treated; among deaths, only 7 of 38 (OR 537.9, 95% CI 29.3-9,877, p < 0.0001). Multiple regression analysis in 44 cases showed that treatment (p < 0.0001) and initial CVC tip position (p = 0.020) were independent predictive factors related to improved cardiac tamponade survival. Past studies have mainly discussed how to avoid pediatric cardiac tamponade; by contrast, the present study focused on how to avoid deaths. The findings of this review suggest that cardiac tamponade survival is better when tamponade is detected early and treated promptly and might be affected by initial CVC tip position.

    We experienced a case in which a central venous catheter (CVC) was misplaced into the wrong vein, which was mistaken for the internal jugular vein (IJV), identified by chest x-ray and ultrasound. The vertebral vein passes through the transverse foramina from the atlas to the 6th cervical vertebra. After exiting the transverse foramen of the 6th vertebra, the vein subsequently runs anterolateral to the vertebral artery and posterior to the IJV and drains the innominate vein. In this case, chest x-ray and ultrasound revealed that the inserted CVC had a course very similar to the vertebral vein. The misplacement of a CVC into the vertebral vein might occur from excessive rotation of the patient's head, which leads to alterations in the cervical vascular anatomy, and from deep insertion of the puncture needle. Therefore, it is advised, for safe CVC insertion, to minimize a patient's head rotation and to make use of ultrasound when the anatomical structures cannot be clearly identified. PMID:25473464

    Central venous catheters (CVC) are used commonly in clinical practice. Incidences of CVC-related right atrial thrombosis (CRAT) are variable, but, when right atrial thrombus is present, it carries a mortality risk of 18% in hemodialysis patients and greater than 40% risk in nonhemodialysis patients. Different pathogenic mechanisms have been postulated for the development of CRAT, which includes mechanical irritation of the myocardial wall, propagation of intraluminal clot, hypercoagulability, and hemodynamics of right atria. Presentation of CRAT may be asymptomatic or may be associated with one of the complications of CRAT like pulmonary embolism, systemic embolism, infected thrombi, or hemodynamic compromise. There are no established treatment guidelines for CRAT. We describe an interesting case of a 59-year-old asymptomatic male successfully treated with open heart surgery after failure of medical treatment for a large CRAT discovered during a preoperative evaluation for a kidney transplant. Our case underscores that early detection of CRAT may carry a favorable prognosis as opposed to waiting until catastrophic complications arise. It also underscores the importance of transesophageal echocardiography in the detection of thrombus and perhaps guides clinicians on which treatment modality to be used according to the size of the thrombus.

    We report a case of a 51-year-old male who developed frequent nonsustained episodes of monomorphic ventricular tachycardia after being diagnosed with bioprosthetic aortic valve endocarditis and treated with intravenous antibiotics. A peripherally inserted central venous catheter (PICC) had been placed without complication less than 24 hours prior to the episodes. Ventricular tachycardia (VT) occurred during the night, while sleeping, when he assumed a right lateral decubitus position with abduction of the right arm and placement of the forearm under his head. VT occurred repeatedly when such position was assumed again upon request, and it would terminate immediately when sitting upright. The PICC was repositioned in the superior vena cava without further VT. He was discharged home the same day and underwent successful aortic valve replacement 2 months later. Position-dependent VT related to PICC requires careful history taking and PICC repositioning to make the diagnosis. X-ray in different patient positions during PICC placement can be considered to evaluate for ventricular migration. PMID:27826374

    Bloodstream infections (BSIs) complicate the management of intensive care unit (ICU) patients. We assessed the clinical and economic impact of BSI among patients of a managed care provider group who had a central venous catheter (CVC) placed in the ICU. We considered hospitalizations occurring between January 1, 2011, and September 30, 2014, that involved an ICU stay during which a CVC was placed. Comparisons were made between episodes where the patient did vs did not develop BSI after CVC insertion. Length of stay, costs of index hospitalization, and total costs over the 180 days after discharge were compared using linear mixed models. Inhospital mortality and 30-day readmission rates were compared using negative binomial regression models. Development of BSI was associated with longer hospital stay (+7 days), more than 3-fold increase in risk of inhospital death, and an additional $129 000 in costs for the index hospitalization. No statistically significant differences in 30-day readmission rates or costs of care over the 180-day period after discharge from the index admission were observed. Bloodstream infections after CVC placement in ICU patients are associated with significant increases in costs of care and risk of death during the index hospitalization but no differences in readmissions or costs after discharge.

    To analyze success rate, dwell-time, and complications of long peripheral venous catheters (L-PVCs) inserted under ultrasound guidance. In difficult venous access (DVA) patients, L-PVC can represent an alternative to central or midline catheters. Prospective observational study. L-PVCs were positioned in DVA patients. The outcome of the cannulation procedure and the times and reasons for catheters removal were analyzed. A 100% placement success rate was documented. The catheter dwell-time was 14.7 ± 11.1 days. Most catheters were removed at end-use in the absence of complications. The rate of catheters appropriately or inappropriately removed before completing the intravenous therapies was 27.7/1000 catheter-days. Two thrombophlebitis (1.91/1000 catheter-days) and 1 catheter-related bloodstream infection (0.96/1000 catheter-days) occurred. L-PVC could be a viable solution in DVA patients, as it may reduce the need for multiple vein punctures, patients' discomfort, and nursing workload. A better adherence to catheter management recommendations should further reduce complications. Copyright © 2016 Elsevier Inc. All rights reserved.

    Interdisciplinary team (IDT) rounds were initiated in the intensive care unit (ICU) in June 2010. All catheters were identified by location, duration, and indication. Catheters with no indication were removed. Data were collected retrospectively on catheter days and associated infections in a 20-month period before and after intervention with an aggregate of 19 207 ICU days before and 23 576 ICU days after institution of rounds. Results showed a statistically significant decrease in the number of indwelling urinary catheter (IUC) days (5304 vs 4541 days, P = .05) and catheter-associated urinary tract infection rates (4.71 vs 1.98 infections/1000 ICU days, P < .05). Central line days statistically increased after IDT rounds (3986 vs 4305 days, P < .05) but the catheter-related bloodstream infection rate trended down (3.5 vs 1.6 infections/1000 ICU days, P = .62). This analysis suggests that IDT rounds may have an impact on reducing the number of IUC days and associated infections.

    Arterio-venous fistulas may develop spontaneously, following trauma or infection, or be iatrogenic in nature. We present a rare case of a jejunal arterio- venous fistula in a 35-year-old man with a history of pancreatic head resection that had been performed two years previously because of chronic pancreatitis. The patient was admitted with acute upper abdominal pain, vomiting and an abdominal machinery-type bruit. The diagnosis of a jejunal arterio-venous fistula was established by MR imaging. Transfemoral angiography was performed to assess the possibility of catheter embolization. The angiographic study revealed a small aneurysm of the third jejunal artery, abnormal early filling of dilated jejunal veins and marked filling of the slightly dilated portal vein (13-14 mm). We considered the presence of segmental portal hypertension. The patient was treated with coil embolization in the same angiographic session. This case report demonstrates the importance of auscultation of the abdomen in the initial clinical examination. MR imaging and color Doppler ultrasound are excellent noninvasive tools in establishing the diagnosis. The role of interventional radiological techniques in the treatment of early portal hypertension secondary to jejunal arterio-venous fistula is discussed at a time when this condition is still asymptomatic. A review of the current literature is included.

    Peripherally inserted central catheters (PICCs) are a common vascular access device used in clinical practice. Their use may be complicated by adverse events such as venous thromboembolism (VTE). The size of the vein used for PICC insertion and thus the catheter to vein ratio is thought to be a controllable factor in the reduction of VTE rates in patients who have a PICC. However, an optimal catheter to vein ratio for PICC insertion has not previously been investigated to inform clinical practice. To determine the effect of the catheter to vein ratio (proportion of the vein measured at the insertion point taken up by the catheter) on rates of symptomatic VTE in patients with a PICC and identify the optimal ratio cut-off point to reduce rates of this adverse event. Adult patients waiting for PICC insertion at a large metropolitan teaching hospital were recruited between May and December 2013. Vein diameter at the PICC insertion site was measured using ultrasound with in-built callipers. Participants were followed up at eight weeks to determine if they developed symptomatic VTE. Data were available for 136 patients (50% cancer; 44% infection; 6% other indication for PICC). Mean age was 57 years with 54% males. There were four cases of confirmed symptomatic VTE (two involving the deep veins, one peripheral vein and one pulmonary embolism). Receiver operator characteristic (ROC) analysis determined that a 45% catheter to vein ratio was the ideal cut off point to maximise sensitivity and specificity (AUC 0.761; 95% CI 0.681-0.830). When a ratio of 46% or above was compared to one that was less than or equal to 45% using a log binomial generalised linear model it was found that participants with a catheter to vein ratio >45% were 13 times more likely to suffer VTE (relative risk 13, p=0.022; CI 1.445-122.788). It was found that a 45% catheter to vein ratio was the optimal cut off with high sensitivity and specificity to reduce the risk of VTE. However, further research

    To describe the management of patients with long-term central venous catheters (CVCs) during an outbreak of infection due to Pseudomonas putida and Stenotrophomonas maltophilia associated with contaminated heparin catheter-lock solution. Descriptive study. Private, 250-bed tertiary-care hospital. In March 2003, we identified 2 febrile cancer patients with P. putida bacteremia. Over 2 days, 7 cases of bacteremia were identified; lots of syringes prefilled with heparin catheter-lock solution, supplied by a compounding pharmacy, were recalled and samples were cultured. More cases of bacteremia appeared during the following days, and any patient who had had a catheter lock infused with the suspect solution was asked to provide blood samples for culture, even if the patient was asymptomatic. Isolates that were recovered from culture were typed by pulsed-field gel electrophoresis. Antimicrobial salvage treatment of long-term CVCs was attempted. A total of 154 patients had had their catheter lock infused with solution from the lots that were suspected of being contaminated. Only 48 of these patients had CVCs. By day 7 of the outbreak, 18 of these patients had become symptomatic. Twenty-six of the remaining 30 asymptomatic patients then also provided blood samples for culture, 10 of whom developed fever shortly after samples were collected. Thirty-two patients were identified who had P. putida bacteremia; 9 also had infection due to S. maltophilia. Samples from 1 of the 3 lots of prefilled syringes in use at the time of the outbreak also grew P. putida on culture. Molecular typing identified 3 different clones of P. putida from patients and heparin catheter-lock solution, and 1 clone of S. maltophilia. A total of 27 patients received antimicrobial therapy regimens, some of which included decontamination of the catheter lock with anti-infective lock solution. Of 27 patients, 19 (70%) retained their long-term CVC during the 6-month follow-up period. To our knowledge, this is

    Over 60% of patients initiating chronic hemodialysis in the United States have a chronic central venous catheter (CVC) as their first blood access device. Although it would be better if these patients started dialysis with fistulas, the CVC is used because it is a reliable and relatively safe method for obtaining blood access over a period of months. Drawing blood from a vein at 300-400 ml/minute is a relatively delicate and somewhat unpredictable process, and there is always a tendency for the vein wall to draw over the arterial tip and obstruct flow. Several methods have been employed to minimize this problem and maximize blood flow, and differing catheter designs have resulted. With all of the different catheter designs now on the market, it is natural to ask what is the logic of different designs. Moreover, in the absence of many direct comparative studies it is natural to ask whether one design is really better than another. There is some misinformation regarding catheter design and function. The following is a list of 10 frequently asked questions In this review, the hydraulic features of CVC are discussed and explained, and logical answers are provided for the following questions: 1. Why do ''D'' catheters flow better than concentric or side by side catheters? 2. Why are all catheters about the same diameter? Does making them bigger really decrease the resistance to flow? 3. Why might a split tip catheter flow better than a solid body catheter? 4. What happens to injections of lock solution at catheter volume? 5. What's better-numerous side holes or none? 6. Why does blood rise into some internal jugular catheters over time, displacing the lock solution? 7. How can a little kink (or stenosis) decrease flow so much? 8. Where should the tips be placed-superior vena cava or right atrium? 9. Which is really better, splitsheath or over-the-wire placement? 10. Which dialysis access has a lower complication rate--CVC or arteriovenous (AV) graft? There remain

    Thrombosis of tunneled central venous catheters (CVC) in hemodialysis (HD) patients is common and it can lead to the elimination of vascular sites. This study aimed to evaluate the incidence of thrombotic obstruction of tunneled CVC in HD patients and the efficacy of occlusion treatment with alteplase use, and identify factors associated with thrombotic occlusion. It was a prospective cohort study performed in two centers which evaluated the diagnosis and treatment of thrombotic occlusion of CVC in HD patients for 24 consecutive months. The catheter occlusion was defined as the difficulty infusing or withdrawing fluid from their paths. Alteplase dose was infused to fill the lumen of the occluded catheter and remained for 50 min. As there was no obstruction of the catheter, the procedure was repeated. Three hundred and thirty-nine CVC in 247 patients were evaluated and followed, totalling 67,244 CVC-days. One hundred fifty-seven patients had only one CVC, 88 patients had two CVC during the study, and two patients had three CVC. The median age was 58 (47-66) years, patients were predominantly men (54%), with diabetic nephropathy as the main cause of chronic kidney disease (44%), the internal jugular vein as the main site of implantation (82%), and duration of dialysis before CVC implantation of 119 (41.5 to 585.5) days. Eight hundred and fifteen occlusion episodes were diagnosed (12 episodes/1000 CVC-days), with primary success with alteplase in 596 episodes (77%) and secondary in 81 cases (10%). In 99 episodes (13%), success was not achieved after the second dose of alteplase. Two hundred and thirty CVC were removed during the study and the removal causes were arteriovenous fistula use in 88 patients (38.3%), infectious and mechanical complications in 89 (38.7%) and 21 (9.1%), respectively, and others (transplantation, transfer, or death) in 32 patients (13.9%). Adverse effects were also not observed. In the multivariate analysis, we identified the greatest number

    To investigate the procedural aspects in inserting central venous catheters that minimise central line-associated bloodstream infection rates in adult intensive care units through a structured literature review. In adult intensive care units, central line-associated bloodstream infections are a major cause of high mortality rates and increased in costs due to the consequences of complications. Eligible articles were identified by combining indexed keywords using Boolean operator of "AND" under databases of Ovid and CINAHL. Titles and abstract of retrieved papers were screened and duplicates removed. Inclusion and exclusion criteria were applied to derive the final papers, which contained seminal studies. The quality of papers was assessed using a special data extraction form. The number of papers retrieved from all databases was 337, reduced to 302 after removing duplicates. Papers were scanned for titles and abstract to locate those relevant to the review question. After this, 250 papers were excluded for different reasons and a total of 52 papers were fully accessed to assess for eligibility. The final number of papers included was 10 articles. Many interventions can be implemented in the adult intensive care unit during the insertion of a central venous catheter to minimise central line-associated bloodstream infections rates. These include choosing the subclavian site to insert the catheters as the least infectious and decolonising patients' skin with alcoholic chlorhexidine gluconate preparation due to its broad antimicrobial effect and durability. Choosing optimal sites for central venous catheter insertion is a complex process that relies on many factors. Furthermore, the introduction of chlorhexidine gluconate preparations should be accompanied with multifaceted interventions including quality improvement initiatives to improve healthcare workers' compliance. As a quality marker in adult intensive care units, healthcare sectors should work on establishing

    Pharmacomechanical thrombolysis (PMT) and catheter-directed thrombolysis (CDT) are commonly used for the treatment of iliofemoral deep venous thrombosis (DVT). The purpose of this study was to examine the short- and long-term venous patency and venous valvular function as well as clinical outcomes of patients treated for iliofemoral DVT by PMT and CDT. A retrospective review of all patients with symptomatic DVT treated between 2006 and 2011 with PMT or CDT was performed. All patients were treated by local tissue plasminogen activator delivered with PMT or CDT. Patients were divided into two groups on the basis of initial treatment modality: patients treated by PMT alone (group 1), and those who underwent PMT and CDT or CDT alone (group 2). Group comorbidities, initial presenting symptoms, and Clinical, Etiologic, Anatomic, and Pathologic (CEAP) classification scores were compared. Postprocedural duplex ultrasound was used to assess valve function and treated vein patency rates. At all visits, Villalta and CEAP scores were recorded and compared. Group demographic and procedural results were analyzed by Fisher exact test for dichotomous variables and Kruskal-Wallis equality-of-populations rank test for the ordinal and continuous data. Kaplan-Meier survival estimates were used to assess preserved valve function as well as primary and secondary patency rates. There were 79 patients with 102 limbs treated for extensive iliofemoral DVT (median age, 51.5 years; range, 16.6-83.8 years). There were 18 patients in group 1 and 61 patients in group 2 (PMT + CDT [n = 54] or CDT alone [n = 7]). There were no differences in demographics or comorbidities between groups aside from malignant disease, which was more common in group 1 (35.3% vs 11.5%; P = .03). A total of 102 limbs were analyzed, 24 in group 1 and 78 in group 2. Patients in group 1 had a shorter symptom duration compared with group 2 (7 days vs 16 days; P = .011).

Prospective, randomized clinical trial. Surgical-trauma intensive care unit (ICU) in a university hospital. All patients admitted to the ICU and requiring the insertion of a central venous and/or an arterial catheter from July 1, 1992 to October 31, 1993. Patients were randomly assigned to one of two groups according to the antiseptic solution used for insertion and catheter care. The same solution was used for skin disinfection from the time of catheter insertion to the time of removal of each catheter. Catheter distal tips were quantitatively cultured when catheters were no longer necessary, if there was a suspicion of catheter-related infection, and routinely after 7 days of use for arterial catheters, or after 15 days of use for central venous catheters. The rate of significant catheter colonization (i.e., > or = 10(3) colony-forming units [cfu]/mL by quantitative culture), and catheter-related sepsis (as defined by sepsis abating following catheter removal per 1,000 catheter-days), were significantly lower in the chlorhexidine group (12 vs. 31 [relative risk 0.4, 95% confidence interval 0.1 to 0.9, p < .01] and 6 vs. 16 [relative risk 0.4, 95% confidence interval 0.1 to 1, p = 0.5], respectively).

    Background: Proper placement of central venous catheter (CVC) tip could reduce early and late catheter-related complications. Although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. Therefore, the present study evaluated the sensitivity and specificity of bedside chest X-ray (CXR) for proper positioning of the catheter tip. Materials and Methods: A total of 82 adult patients undergoing elective placement of tunneled CVC were enrolled in this study during 2010-2012. The catheter tip position was evaluated by postoperative bedside chest radiographs as well as trans-thoracic echocardiogram as definite diagnostic tool. The catheter position was considered correct if the tip was positioned in the right atrium both in CXR or echocardiography. Finally, CXRs interpreted by expert radiologist. Thus findings were compared by echocardiography. Sensitivity, specificity, accuracy, positive, and negative predictive values were calculated. Data were analyzed using SPSS version 16 (SPSS Inc., Chicago, IL), and P < 0.05 considered as significant. Results: The patients were 57.37 ± 18.91 years of age, weighed 65.79 ± 15.58 kg and were 166.36 ± 9.91 cm tall. Sensitivity and specificity of CXR for proper catheter tip position were 74.3% and 58.3%, respectively. Positive and negative predictive values were 91.2% and 28%. In addition accuracy, positive likelihood ratio, and negative likelihood ratio were 71.9%, 1.78, and 2.27 respectively. Conclusion: Bedside CXR alone does not reliably predict malpositioning after CVC placement. PMID:25767527

    Abdominal compartment syndrome (ACS) is associated with high morbidity and mortality rates. Therefore, the need for a good diagnostic tool to predict intra-abdominal hypertension (IAH) and progression to ACS is paramount. Bladder pressure (BP) has been used for several years for intra-abdominal pressure (IAP) measurement but has the disadvantage that it is not a continuous measurement. In this study, a single-lumen central venous catheter (CVC) is placed through the abdominal wall into the abdominal cavity to continuously and directly monitor the intraabdominal pressure (CDIAP). The aim of this study was to evaluate the use of CDIAP to measure BP as a representative of the true IAP. Both BP and CDIAP were prospectively recorded on a variety of surgical patients admitted to the intensive care unit (ICU) from March 2003 up to December 2004. At the end of the surgical procedure, the CVC was placed through the abdominal wall and connected to a pressure transducer. In addition, the BP was measured through the urine drainage port after clamping the catheter and filling the bladder with 50 ml of 0.9% saline. At least three paired measurements (BP and CDIAP) were performed for at least one day on the ICU in a standardized manner at preset time intervals on each patient. The paired measurements were compared using the Bland-Altman (B-A) method. Data are presented as mean ± standard deviation. Over a period of 22 months (March 2003 until December 2004), 125 paired measurements of both BP and CDIAP were recorded on 25 patients. The mean age was 72.4 ± 6.6 years. Eighteen patients underwent central vascular surgery, and seven patients with peritonitis received laparotomy. The mean CDIAP was 11.4 ± 4.8 (range 2-30) mmHg, and the BP was 12.9 ± 5.3 (range 3-37) mmHg. The mean difference between CDIAP and BP was 1.6 ± 2.7 mmHg. There was an acceptable level of agreement (intraclass correlation 0.82) between IAP measured by BP and IAP measured via CDIAP. Continuous direct

    Antimicrobial releasing biomaterial coatings have found application for instance in the fixation of orthopedic joint prostheses and central venous catheters. Most frequently, the release kinetics is such that antimicrobially-effective concentrations are only reached within the first days to weeks after implantation, leaving no local antimicrobial release available when a biomaterial-associated infection occurs later. Here we compare the ad libitum release of chlorhexidine and silver-sulfadiazine from a central venous catheter with their release from a new, on-demand release coating consisting of a temperature-sensitive copolymer of styrene and n-butyl (meth)acrylate. The copolymer can be loaded with an antimicrobial, which is released when the temperature is raised above its glass transition temperature. Ad libitum release of chlorhexidine and silver-sulfadiazine from a commercially-purchased catheter and associated antimicrobial efficacy against Staphylococcus aureus was limited to 16days. Consecutive temperature-triggers of our on-demand coating yielded little or no antimicrobial efficacy of silver-acetate release, but antimicrobially-effective chlorhexidine concentrations were observed over a time period of 60-80days. This attests to the clear advantage of on-demand coatings above ad libitum releasing coatings, that may have released their antimicrobial content before it is actually needed. Importantly, glass transition temperature of chlorhexidine loaded copolymers was lower (48°C) than of silver loaded ones (61°C), facilitating their clinical use.

    The goal was to determine the interchangeability of peripheral venous catheter (PVC) and venipuncture blood sampling (BS). Paired blood samples from hospitalized children were obtained through venipuncture and from existing PVCs, following discard of 2 mL of blood. Comparisons of 9 complete blood count indices (white and red blood cell counts, hemoglobin and hematocrit levels, mean corpuscular volume, mean corpuscular hemoglobin level, red blood cell distribution width, platelet count, and mean platelet volume) and 5 basic chemical analysis indices (sodium, potassium, glucose, chloride, and urea levels) were performed, and hemolysis was documented. Irrespective of gauge, blood samples were obtained successfully from 40 (85.1%) of 47 PVCs, with no abnormal hemolysis. BS through venipuncture took longer than BS from PVCs (175.8 +/- 229.6 vs 104.5 +/- 53.4 seconds; P = .053) and was associated with significantly more distress/crying (73.1% vs 0%; P < .001). There were no significant differences between venipuncture and PVC samples (paired t test). Twenty-one (6%) of 348 pairs analyzed with the Clinical Laboratory Improvement Amendment standards fell outside the range of acceptable variance (8 of 21 aberrations were attributed to glucose measurements). Bland-Altman analysis indicated that, with the exclusion of glucose measurements, BS from PVCs is reliable, with 29 (6.5%) of 448 pairs exceeding the limits of agreement. Of those, 9 cases were clinically significant, but none would have altered clinical management. PVC sampling was shown to be a pain-reducing method that can be used for children for selected basic analytes. The findings for glucose were unreliable.

    Peripheral venous catheters (PVCs) can be associated with serious complications. We evaluated the effect of education and feedback on processes related to PVC placement. We implemented an educational intervention in a 72-bed Emergency Department (ED) over 12 months (4 periods, each a quarter). During preimplementation period, we evaluated PVC placement, condition, accurate documentation, and demonstration of aseptic steps for medication infusion. With implementation, ED nurses had formal education, with direct observations and feedback. For postimplementation periods 1 and 2, we continued direct observations and feedback, reducing the number of audits per week. Of 2,568 PVCs evaluated in the ED, accurate documentation on dressing improved from 83 of 803 (10.3%) preimplementation to 300 of 476 (63%) at the end of the study (P < .0001). Correct documentation in ED records improved from 498 of 803 (62%) preimplementation to 409 of 476 (85.9%) at the end of study (P < .0001). We observed 273 attempts to place PVC; of them, 220 (80.6%) were completed. The overall compliance with the procedure steps was very poor preimplementation (n = 3/63, 4.8%) and improved in implementation (n = 17/55, 30.9%) and postimplementation periods 1 (n = 19/60, 31.7%) and 2 (n = 14/42, 33.3%, P < .0001). ED health care workers showed significant improvement in knowledge with education. Education and real-time feedback to ED health care workers are associated with an increased and sustained compliance with processes to reduce the risk of infection from PVCs.

    Measurement of central line-associated bloodstream infection (CLABSI) rates outside of intensive care units is challenged by the difficulty in reliably determining central venous catheter (CVC) use. The National Healthcare Safety Network (NHSN) allows for use of electronic data for determination of CVC-days, but validation of electronic data has not been studied systematically. To design and validate a process to reliably measure CVC-days outside of the intensive care units that leverages electronic documentation. Thirty-four inpatient wards at 2 academic hospitals using a common electronic platform for nursing documentation were studied. Electronic queries were created to capture patient and CVC information, and tools and processes for tracking and reporting errors in documentation were developed. Strategies to validate electronic data included comparisons with manual CVC-day determinations and automated data validation using customized tools. Interventions included redesign of documentation interface, real-time audit with feedback of errors, and education. The primary outcome was patient-level total error rate in electronic CVC-day measurement compared with manually counted CVC-days. At baseline, there were a mean (± standard deviation) of [Formula: see text] electronic CVC-day errors (omission and commission errors summed and counted equally) per manually counted CVC-day. After several process improvement cycles over 7 months, the error rate decreased to <0.05 errors per CVC-day and remained at or below this level for 2 years. Baseline electronic CVC-day counts had a high error rate. Stepwise interventions reduced errors to consistently low levels. Validation of electronic calculation of CVC-days is essential to ensure accuracy, particularly if these data will be used for interinstitutional comparison.

    Spinal infections are a rare yet serious metastatic complication of bacteremia among patients with long-term central venous catheters (CVCs) for which clinicians must remain vigilant. We performed a retrospective review of all cases of spinal infection occurring in the context of a CVC for long-term parenteral nutrition (PN) managed in our department between January 2010 and October 2013, a cohort of 310 patients over this time period. Six patients were identified (mean age, 65 years; 5 male). One hundred percent of patients presented with spinal pain (5/6 cervical, 1/6 thoracic). Organisms were cultured from the CVC in 5 of 6 patients. In all cases, the white blood cell count was normal, and in 5 of 6, C-reactive protein was normal. All diagnoses were confirmed on magnetic resonance imaging (MRI), and in 3 of 6 cases, an MRI was repeated (on the advice of neurosurgical colleagues) to confirm resolution of changes after a period of antimicrobial therapy. There was no clear correlation between duration of PN or number of days following CVC insertion and onset of infection. The CVC was replaced in 4 of 6 patients at the time of diagnosis, delayed removal in 1 of 6, and salvaged in the remaining case. Although rare, a high index of suspicion is needed in patients receiving long-term PN who present with spinal pain. Peripheral inflammatory markers may not be elevated. MRI should be performed and patients should be treated with antibiotics alongside involvement of local microbiology and neurosurgical teams. Multidisciplinary discussion on CVC salvage in these cases is important, especially in cases of challenging vascular anatomy.

    Central venous catheters (CVC) related thrombosis (CRT) represents a well known complication in patients with acute myeloid leukemia (AML) receiving intensive chemotherapy but the efficacy of antithrombotic prophylaxis still remains controversial. We analyzed 71 consecutive AML patients whose CVC was inserted before each chemotherapy cycle for an overall number of 106 CVC placements. In 47/106 insertions, a prophylaxis with 100 IU/kg/day low molecular weight heparin (LMWH) was administered for 7 days after CVC insertion and additional 7 after CVC removal. This unconventional dose of LMWH, although higher than usual, appeared adequate for a short-course approach. LMWH was delivered regardless of the platelet (PLT) count once provided that it should have been maintained above 20 x 10(9)/L by transfusions. Of 106 insertions, we observed 19 (18%) episodes of CRT, 58 (54%) of sepsis and 50 (47%) infections of CVC-exit site with no difference between LMWH and no-LMWH group. Occurrence of CRT was significantly associated with CVC-exit site infections (14/19, p=0.01) and sepsis (16/19, p=0.005) with no difference between LMWH and no-LMWH group. In multivariate analysis, both CVC-exit site infections and sepsis were confirmed to be independent risk factors for CRT development. Our retrospective study, although based on a small sample size, suggests that the occurrence of CVC-exit site infections and neutropenic sepsis following chemotherapy significantly increases the risk of CRT in AML, independently from the use of LMWH prophylaxis. © 2013.

    Chronic indwelling central venous catheters can result in formation of fibrin sheaths increasing risk of occlusion, thrombosis and infection. Endovascular infection of right-sided heart structures induced by such sheaths is very rare. A 48-year-old woman with end-stage renal disease initially treated for diabetic ketoacidosis developed persistent Staphylococcus epidermidis bacteraemia without an identifiable source. Although transthoracic echocardiography was unremarkable, transoesophageal echocardiography revealed a fibrin sheath and vegetations in superior vena cava-right atrium junction, which was the site of the tip of a central catheter that had been removed 2 months prior, consistent with fibrin sheath-associated endovascular infection. The bacteraemia cleared and clinical improvement was seen with prolonged intravenous vancomycin. In patients with unexplained bacteraemia and history of a central catheter, rare causes of endovascular infections of right-sided heart structures like fibrin sheaths should be considered. These can persist months after catheter removal. Transoesophageal echocardiogram should be used for earlier detection. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    To report the efficacy of a new percutaneous technique for extraction of embolized catheters, five female patients (62 ± 14 years) referred to our institution were analyzed. With the combination of a large-diameter steerable sheath with a sizeable snare system, three dislodged Port-A-Cath tubes and two ventriculoatrial shunts were retrieved successfully. Mean procedure time was 51 ± 23 min, biplane fluoroscopy time was 22 ± 21 min, and dose area product was 1188 ± 992 dGy cm(2). Percutaneous extraction of embolized venous catheters is highly effective with the help of this novel, self-assembled system. The presented technique provides major advantages with respect to three-dimensional steerability and should be considered for complex cases.

    Catheter-related central thrombosis is a rare complication of long-term central line. We describe the case of an asymptomatic boy who was diagnosed a calcified thrombus in right atrium eight years after the removal of a long-term central venous device. Although the most appropriate therapeutic approach for managing floating right heart thrombi remains to be determined, surgical removal is an effective and safe procedure for calcified long-standing thrombus and it is to be preferred in elective conditions especially in young asymptomatic patients without hemodynamic involvement, that are at low risk of surgery-related morbidity and mortality.

    Peri-operative high-calorie nutrition was administered, through a total of 500 catheters introduced into the superior vena cava via the subclavian vein, to 404 patients admitted to hospital for gastro-intestinal cancer resection or other major abdominal operations, some of them taking a complicated course. Most of the catheters remained in situ for 6-20 days; the longest period was 44 days. Catheter insertion was successful in 97.8%. Faulty position of the catheter occurred in 4.4%; in 2.8% it was rectified under fluoroscopic control. In 92.2% there were no complications ascribable to the catheter. A pneumothorax resulted in 1.4% of patients, central thrombosis in 0.4%. Catheter-related sepsis was noted in 6.2%.

    Venous access by cannulation of the central vein is a necessary prerequisite of the oncological treatment. Within the period 1998-2001 there 395 CVCs (Central Venous Catheters) were introduced using a subcutaneous tunnel in 335 hospitalised patients at the Clinic of the Child Surgery, Orthopaedics and Traumatology FN Brno. In 310 patients Hickman CVC was used and in 25 Groshong CVC. Using the vena subclavia 1. dx., 131 CVCs were introduced, via the vena subclavia 1. sin. 264 CVCs. The average period of CVCs introduction was 3 months. In 78 introduced CVCs infectious complication developed. A local infection was noticed only 8 times, general infection at 70 cases. In 13 patients CVCs had to be removed. The authors present their experience with the introduction of tunneled CVCs in oncological patients and the options for solving the infectious complications when using CVCs.

    Catheters are the leading source of bloodstream infections in critically ill patients. Because the clinical signs of infection are nonspecific, such infections are overly suspected, which results in unnecessary removal of catheters. A conservative approach might be attempted in mild infections, whereas catheters should always be removed in cases of severe sepsis or septic shock. Nowadays, comprehensive unit-based improvement programs are effective to reduce catheter-related bloodstream infections (CR-BSIs). Rates of CR-BSI higher than 2 per 1000 catheter-days are no longer acceptable. A locally adapted checklist of preventive measures should include cutaneous antisepsis with alcoholic preparation, maximal barrier precaution, strict policy of catheter maintenance, and ablation of useless catheters. Antiseptic dressings and, to a lesser extent, antimicrobial-coated catheters, might be added to the prevention strategies if the level of infections remains high despite implementation of a prevention program. In the case of CR-BSI in intensive care units (ICUs), the catheter should be removed. In the case of persistence of fever or positive blood cultures after 3 days, inadequate antibiotic therapy, endocarditis, or thrombophlebitis should be ruled out.

    Over the last decade, significant advances have been made in percutaneous treatment of structural heart diseases. Many of these interventions require insertion of large caliber sheaths in the femoral veins. Manual compression, compression devices, and various closure devices have been used for removal of large-sized venous sheaths. Here, we describe the use of a temporary subcutaneous "Figure-of-Eight" suture technique for venous access site closure after removal of large-caliber sheaths.

    We describe a case of a patient with a functional kidney transplant who was admitted to our department with clinically evident central vein stenosis (CVS) 7 years after the removal of a central venous catheter (CVC) from the right internal jugular vein. The catheter was used as a hemodialysis access for a 2-month period. In the interval before his last admission, the patient suffered two episodes of deep vein thrombosis. Investigation revealed heterozygosity for factor V Leiden, the most common inherited thrombophilia encountered in 5% of Caucasians, and anticoagulation treatment was started. Magnetic resonance angiography showed stenosis just after the convergence of the right subclavian vein with the internal jugular vein to the innominate vein. Transluminal angioplasty restored venous patency and right upper arm edema resolved. Coexistence of CVS, accompanied by hemodynamic changes and endothelial dysfunction, with thrombophilia fulfill all the elements of the Virchow's triad. Therefore, the patient was at great risk for central vein thrombosis, from which he was possibly protected by the early administration of anticoagulant treatment. This case indicates that CVS can be asymptomatic for several years after CVC removal and also raises the question if thrombophilia workup and investigation for CVS may be beneficial in every patient with CVC placement in order to avoid any harmful outcomes.

    To evaluate and compare the risk of long-term central venous catheter (CVC) infection in human immunodeficiency virus (HIV)-infected and cancer patients. Prospective multicenter cohort study based on active surveillance of long-term CVC manipulations and patient outcome over a 6-month period. Services of infectious diseases and oncology of 12 university hospitals in Paris, France. In 1995, all HIV and cancer patients with solid malignancy were included at the time of long-term CVC implantation. Overall, 31.6% of long-term CVC infections were identified in 32% of 201 HIV and 5% of 255 cancer patients. Most were associated with bacteremia, most commonly coagulase-negative staphylococci. The long-term CVC time-related infection risk was greater in HIV than in cancer patients (3.78 vs 0.39 infections per 1,000 long-term CVC days; P<.001). The independent risk factors of long-term CVC infection were as follows: in HIV patients, frequency of long-term CVC handling and neutropenia; in cancer patients, poor Karnofsky performance status; in both HIV and cancer patients, recent history of bacterial infection. The risk of long-term CVC infection was similar for tunneled catheters and venous access ports in each population. Prevention of long-term CVC infection should focus first on better sterile precautions while handling long-term CVC, especially in HIV patients who have frequent and daily use of the long-term CVC.

    Nek2 (NIMA-related kinase 2) is a serine-threonine kinase and human homolog of the mitotic regulator NIMA of Aspergillus nidulan. We reported the efficiency of Nek2 siRNA in several cancer xenograft models using cholangiocarcinoma, breast cancer and colorectal cancer. Pancreatic cancer is difficult to treat due to its rapid progression and resistance to chemotherapy. Novel treatments are urgently required to improve survival in pancreatic cancer, and siRNA are a promising therapeutic option. However, finding an in vivo drug delivery system of siRNA remains a major problem for clinical application. In this study, the overexpression of Nek2 was identified in pancreatic cancer cell lines. Nek2 siRNA inhibited tumor growth in a subcutaneous xenograft mouse model of pancreatic cancer, prolonged the survival time in an intraperitoneal xenograft mouse model and efficiently prevented the progression of liver metastasis using a portal venous port-catheter system. Taken together, Nek2 is an effective therapeutic target in pancreatic cancer. An adequate delivery system is considered important in treating advanced pancreatic cancer, such as peritoneal dissemination and liver metastasis. Further investigations are required on the safety and side effects of the portal venous port-catheter system. We hope that Nek2 siRNA will be a novel therapeutic strategy for pancreatic cancer with liver metastasis and peritoneal dissemination.

    Femoral or subclavian central venous catheters are commonly used for temporary vascular access in haemodialysis. We used 36 tunnelized siliconed double lumen catheter (Quinton Permcath or Hickman Bard), most of them in right internal jugular percutaneously. Indication for this catheter were acute or chronic renal failure, plasma exchange, rescue of arterio venous fistula or peritoneal dialysis. Insertion incidents were minors (local haematoma), mean functional time was 51 days. Catheters were changed in 5 cases of infection, 3 cases of obstruction and in 2 accidental remove. Insertion facility, low morbidity, potentially long time use, high blood flow rate with low recirculation argue for this expensive material.

    Critically ill pediatric patients, especially in the intensive care unit, receive multiple medications and have a higher risk of central venous catheter (CVC) occlusion. If an occlusion occurs immediately after the administration of multiple medications or incompatible medications, either an acidic solution such as 0.1 N hydrochloric acid (HCl) or a basic solution of 1 mEq/mL sodium bicarbonate or 0.1 N sodium hydroxide can be used. However, compounding and storing of 0.1 N HCl has become more complex due to USP <797> guidelines for sterile compounding, and an alternative is needed. We report a series of cases in which L-cysteine was used instead of HCl to clear CVCs occluded due to administration of multiple medications. L-cysteine is a commercially available, sterile solution with a pH of 1–2.5. CVC occlusion was resolved in 10 of the 16 episodes in 13 patients. Two of the 16 occlusions were phenytoin related and would not have responded. An L-cysteine dose of 50 mg was used during 10 of the 16 episodes, 100 mg during 5 episodes, and 25 mg during 1 episode. A correlation between catheter clearance and dose was not observed. Occlusion resolution due to L-cysteine was not correlated to the prior use of tissue plasminogen activator. Metabolic acidosis, adverse effects, or damage to the catheters due to L-cysteine were not observed. On the basis of this limited experience, we propose L-cysteine as an effective alternative to 0.1 N HCl for clearing CVC occlusions caused by drugs with an acidic pKa.

    Transvenous lead extraction can be a method to regain venous access. We present the case of a man, aged 67, with indications to upgrade an ICD to a resynchronization therapy device. Since innominate vein occlusion was diagnosed and extraction of an abandoned ventricular pacing lead did not provide lumen regain, a functional atrial lead was extracted with the femoral approach to stabilization and venous access was regained. Asymptomatic vein wall damage but no other complications were recorded. The simultaneous application of different techniques to regain venous access may allow success of the final procedure in system upgrading. PMID:24570742

    Purpose: Despite some advantages to their use, long-term central venous catheters (CVCs) are associated with complications for patients who require chemotherapy. Understanding of these risks in commercially insured populations is limited. This information can inform medical policies that ensure the appropriate use of venous access devices. This study's objectives were to assess the extent of variation in use of long-term CVCs in a cohort of commercially insured women with breast cancer, and to assess risks of associated complications. Methods: Retrospective cohort analysis was conducted using health insurance claims between January 2006 and October 2013. The cohort included commercially insured women age ≥ 18 years diagnosed with breast cancer who received infusion chemotherapy (N = 31,047). We conducted matched and case-mix adjusted Cox proportional hazard modeling to assess differences in bloodstream infections and thrombovascular complications between patients using long-term CVCs and those using temporary intravenous catheters. Results: Approximately two thirds of the cohort had a long-term CVC, although rates varied across regions (57% to 75%), health plans (65% to 70%), and insurance coverage (63% to 68%). After propensity score matching, the adjusted hazard ratio for infection was 2.70 (95% CI, 2.31 to 3.16) and thrombovascular complications, 2.61 (95% CI, 2.33 to 2.93) in patients with long-term CVCs compared with those with temporary intravenous catheters. Conclusion: Although long-term CVCs may have benefits, they are associated with increased morbidity. Regional and health plan variation in long-term CVC insertion suggests that some of their use reflects provider- or institution-driven variation in practice. Evidence-based guidelines and tools may help decrease discretionary use of long-term CVCs. PMID:26265170

    PurposePercutaneous mechanical thrombectomy (PMT) is now established as an alternative treatment of acute arterial occlusions in addition to fibrinolysis and surgical thrombectomy. The objective of this retrospective study was the investigation of a rotational atherothrombectomy catheter in terms of safety and efficacy in the treatment of acute and subacute femoropopliteal bypass occlusions.Materials and MethodsForty-two patients (average age 65.8 {+-} 9.1 years) with acute (<14 days [n = 31]) and subacute (14-42 days [n = 11]) femoropopliteal bypass occlusions were treated consecutively with a rotational debulking and removal catheter (Straub Rotarex). The average occlusion length was 28.4 {+-} 2.9 (24-34) cm. Thirty-four (81 %) patients underwent venous bypass, and 8 (19 %) patients underwent polytetrafluoroethylene bypass.ResultsThe technical success rate was 97.6 % (41 of 42). In 1 patient, blood flow could not be restored despite the use of the atherothrombectomy system. The average catheter intervention time was 6.9 {+-} 2.1 (4-9) min. Ankle-brachial index increased from 0.39 {+-} 0.13 to 0.83 {+-} 0.11 at discharge and to 0.82 {+-} 0.17 after 1 month (p < 0.05). There were a total of 2 (4.8 %) peri-interventional complications: One patient developed a distal embolism, which was successfully treated with local lysis, and another patient had a small perforation at the distal anastomosis, which was successfully treated with a stent.ConclusionPMT with the Rotarex atherothrombectomy catheter represents a safe and effective option in the treatment of acute and subacute femoropopliteal bypass occlusions because it can quickly restore blood flow.

    To compare the efficacy of two commercially available, alcohol-based antiseptic solutions for preparation and care of central venous catheter (CVC) insertion sites, with and without octenidine dihydrochloride, a double-blind, randomized, controlled trial was undertaken in the haematology units and in one surgical unit of two university hospitals. Adult patients with a non-tunnelled CVC were randomly assigned to two different skin disinfection regimens at the insertion site: 0.1% octenidine with 30% 1-propanol and 45% 2-propanol, and as control 74% ethanol with 10% 2-propanol. Endpoints were (i) skin colonization at the insertion site; (ii) positive culture from the catheter tip (> or = 15 CFU); and (iii) occurrence of CVC-associated bloodstream infection (defined according to criteria set by the CDC). Four hundred patients with inserted CVC were enrolled from May 2002 through April 2005. Both groups were similar in respect of patient characteristics and co-morbidities. Skin colonization at the CVC insertion site during the first 10 days was significantly reduced by octenidine treatment (relative difference octenidine vs. control: 0.21; 95%CI: 0.11-0.39, p <0.0001). Positive culture of the catheter tip was significantly less frequent in the octenidine group (7.9%) than in the control group (17.8%): OR = 0.39 (95%CI: 0.20-0.80, p 0.009). Patients treated with octenidine had a non-significant reduction in catheter-associated bloodstream infections (4.1% vs. 8.3%; OR = 0.44; 95%CI: 0.18-1.08, p 0.081). Side effects were similar in both groups. This randomized controlled trial supports the results of two observational studies demonstrating octenidine in alcoholic solution to be a better option than alcohol alone for the prevention of CVC-associated infections.

    Patients with difficult intravenous access (DIVA) often experience discomfort because of failed attempts to place peripheral venous catheters (PVCs); however, ultrasound guidance may improve this problem with catheter placement. The aim of this study was to evaluate the use of ultrasound when operated by nurse anesthetists for these patients. This prospective observational study with a pre/post design focused on inpatients with DIVA referred for PVC placement, a service provided by nurse anesthetists in most Scandinavian hospitals. The rate of success, procedure time, number of skin punctures, discomfort, catheter size, location, and incidence of central venous catheter placement are reported before and after implementation of a training program and a mobile service using ultrasound to place difficult-to-place PVCs. The success rate increased from 0% (0 of 33 patients) to 83% (58 of 70 patients) with ultrasound. Procedure time was reduced from 20 to 10 minutes, discomfort was unchanged, and the median number of skin punctures decreased from 3 to 2. The incidence of central venous catheter placement dropped from 34% to 7%. Implementation of a training program and a mobile service in which nurse anesthetists performed ultrasound-guided PVC placement improved the success rate and quality of care in patients with DIVA.

    US Centers for Disease Control guidelines recommend replacement of peripheral intravenous (IV) catheters no more frequently than every 72 to 96 hours. Routine replacement is thought to reduce the risk of phlebitis and bloodstream infection. Catheter insertion is an unpleasant experience for patients and replacement may be unnecessary if the catheter remains functional and there are no signs of inflammation. Costs associated with routine replacement may be considerable. This is an update of a review first published in 2010. To assess the effects of removing peripheral IV catheters when clinically indicated compared with removing and re-siting the catheter routinely. For this update the Cochrane Vascular Trials Search Co-ordinator searched the Cochrane Vascular Specialised Register (March 2015) and CENTRAL (2015, Issue 3). We also searched clinical trials registries (April 2015). Randomised controlled trials that compared routine removal of peripheral IV catheters with removal only when clinically indicated in hospitalised or community dwelling patients receiving continuous or intermittent infusions. Two review authors independently assessed trial quality and extracted data. Seven trials with a total of 4895 patients were included in the review. The quality of the evidence was high for most outcomes but was downgraded to moderate for the outcome catheter-related bloodstream infection (CRBSI). The downgrade was due to wide confidence intervals, which created a high level of uncertainty around the effect estimate. CRBSI was assessed in five trials (4806 patients). There was no significant between group difference in the CRBSI rate (clinically-indicated 1/2365; routine change 2/2441). The risk ratio (RR) was 0.61 (95% CI 0.08 to 4.68; P = 0.64). No difference in phlebitis rates was found whether catheters were changed according to clinical indications or routinely (clinically-indicated 186/2365; 3-day change 166/2441; RR 1.14, 95% CI 0.93 to 1.39).

    Objective: To compare the efficacy of two concentrations of heparin to clear the lumen of in vitro clotted neonatal peripherally inserted central catheters (PICCs). Methods: This is an in vitro, experimental quantitative study of 76 neonatal 2.0-Fr PICCs coagulated in vitro. The catheters were divided into two groups of 38 PICCs each. In both groups an infusion of low molecular weight heparin was administered with a dose of 25IU/mL for Group 1 and 50IU/mL for Group 2. The negative pressure technique was applied to the catheters of both groups at 5, 15 and 30min and at 4h to test their permeability. Kaplan-Meier survival analysis was used to verify the outcome of the groups according to time intervals. Results: The comparison between both groups in the first 5min showed that more catheters from Group 2 were cleared compared to Group 1 (57.9 vs. 21.1%, respectively). Kaplan-Meier survival analysis showed that less time was needed to clear catheters treated with 50IU/mL of heparin (p<0.001). Conclusions: The use of low molecular weight heparin at a concentration of 50IU/mL was more effective in restoring the permeability of neonatal PICCs occluded in vitro by a clot, and the use of this concentration is within the safety margin indicated by scientific literature.

    To evaluate the cost-effectiveness, from the funding body's point of view, of real-time ultrasound-guided central venous catheter insertion compared to the traditional method, which is based on the external anatomical landmark technique. A theoretical simulation based on international literature data was applied to the Brazilian context, i.e., the Unified Health System (Sistema Único de Saúde - SUS). A decision tree was constructed that showed the two central venous catheter insertion techniques: real-time ultrasonography versus external anatomical landmarks. The probabilities of failure and complications were extracted from a search on the PubMed and Embase databases, and values associated with the procedure and with complications were taken from market research and the Department of Information Technology of the Unified Health System (DATASUS). Each central venous catheter insertion alternative had a cost that could be calculated by following each of the possible paths on the decision tree. The incremental cost-effectiveness ratio was calculated by dividing the mean incremental cost of real-time ultrasound compared to the external anatomical landmark technique by the mean incremental benefit, in terms of avoided complications. When considering the incorporation of real-time ultrasound and the concomitant lower cost due to the reduced number of complications, the decision tree revealed a final mean cost for the external anatomical landmark technique of 262.27 Brazilian reals (R$) and for real-time ultrasound of R$187.94. The final incremental cost of the real-time ultrasound-guided technique was -R$74.33 per central venous catheter. The incremental cost-effectiveness ratio was -R$2,494.34 due to the pneumothorax avoided. Real-time ultrasound-guided central venous catheter insertion was associated with decreased failure and complication rates and hypothetically reduced costs from the view of the funding body, which in this case was the SUS.

The probabilities of failure and complications were extracted from a search on the PubMed and Embase databases, and values associated with the procedure and with complications were taken from market research and the Department of Information Technology of the Unified Health System (DATASUS). Each central venous catheter insertion alternative had a cost that could be calculated by following each of the possible paths on the decision tree. The incremental cost-effectiveness ratio was calculated by dividing the mean incremental cost of real-time ultrasound compared to the external anatomical landmark technique by the mean incremental benefit, in terms of avoided complications. Results When considering the incorporation of real-time ultrasound and the concomitant lower cost due to the reduced number of complications, the decision tree revealed a final mean cost for the external anatomical landmark technique of 262.27 Brazilian reals (R$) and for real-time ultrasound of R$187.94. The final incremental cost of the real-time ultrasound-guided technique was -R$74.33 per central venous catheter. The incremental cost-effectiveness ratio was -R$2,494.34 due to the pneumothorax avoided. Conclusion Real-time ultrasound-guided central venous catheter insertion was associated with decreased failure and complication rates and hypothetically reduced costs from the view of the funding body, which in this

    Peripheral venous catheters (PVCs) are the simplest and most frequently used method for drug, fluid, and blood product administration in the hospital setting. It is estimated that up to 90% of patients in acute care hospitals require a PVC; however, PVCs are associated with inherent complications, which can be mechanical or infectious. There have been a range of strategies to prevent or reduce PVC-related complications that include optimizing patency through the use of flushing. Little is known about the current status of flushing practice. This observational study quantified preparation and administration time and identified adherence to principles of Aseptic Non-Touch Technique and organizational protocol on PVC flushing by using both manually prepared and prefilled syringes.

    We prospectively studied 45 central venous catheters to determine whether Gram's staining and culture of skin swabs from the entry site could be used to predict catheter-related infection. Data were collected from insertion site swabs, intracutaneous and intravascular catheter segments, and blood cultures. Surveillance site cultures at the time of dressing changes showed that bacterial growth, once established, persisted until removal of the catheter but that the time of onset of infection was not predictable. Gram's staining alone and Gram's staining combined with culture were tested for their ability to predict catheter colonization and catheter-related infection. Bacteria seen with Gram's staining invariably denoted catheter colonization. When bacteria were not seen with Gram's staining, positive results of culture did not change the pretest probabilities of colonization or infection; however, negative results of culture reduced the probability of colonization to low levels (likelihood ratio less than 0.06). We conclude that Gram's staining and culture of skin swabs from the entry site provide, without line removal, a simple, inexpensive and practical test for the diagnosis of catheter-related infection.

    Tachycardia arising from the pulmonary venous atrium (PVA) has not been adequately characterized in the setting of surgically repaired congenital heart disease (CHD). The purpose of this study was to determine the mechanisms, approach, and outcomes of catheter ablation of PVA tachycardia after CHD repair. The adult CHD procedural database was searched for consecutive ablation procedures over a 4-year period. Procedural characteristics of the population with tachycardia arising from the PVA were compared to those without PVA tachycardia. Groups were classified as (1) biventricular CHD, (2) single ventricle, or (3) d-transposition of the great arteries (DTGA)-baffle. Complete 3-dimensional mapping was possible for 113 of 124 sustained tachycardias during 81 procedures. Of these, 31 (19%) arose from the PVA, including 11 (15%) tachycardias in biventricular CHD, 8 (31%) in single ventricle, and 12 (80%) in DTGA-baffle procedures. Intra-atrial reentrant tachycardia was less frequently observed in the PVA vs the systemic venous atrium (SVA) (P = .012). Independent predictors of PVA tachycardia were absence of biventricular CHD (odds ratio 0.19, confidence interval 0.05-0.64, P = .010) and ipsilateral atrial surgery (odds ratio 15.7, confidence interval 4.8-59.9, P <.001). PVA procedure duration was greater than SVA-only procedures (median 5.3 hours vs 4.0 hours, P = .012), but acute success was similar (87% vs 82%, respectively, P = NS). PVA tachycardia is not unusual after surgical repair of CHD. Predictors include ipsilateral atrial surgery and absence of biventricular CHD. Such procedures involve increased complexity and unique tachycardia substrates but appear equally amenable to catheter ablation. Published by Elsevier Inc.

    The current paper reports on the predicting factors associated with satisfactory peripheral blood stem cell collection and the efficacy of large-volume leukapheresis (LVL) using femoral vein catheterization to harvest PBSCs with Fenwal CS 3000 Plus from normal healthy donors for allogeneic transplantation. A total of 113 apheresis procedures in 57 patients were performed. The median number of MNCs, CD3+ cells, and CD34+ cells harvested per apheresis was 5.3 x 10(8)/kg (range, 0.3-11.0 x 10(8)/kg), 3.0 x 10(8)/kg (range, 0.2-6.6 x 10(8)/kg), and 7.9 x 10(6)/kg (range, 0.1-188.9 x 10(6)/kg), respectively. The median collection efficiency of MNCs and CD34+ cells was 49.8% and 49.7%, respectively. A highly significant correlation was found between the collected CD34+ cell counts and the pre-apheresis WBC counts in the donors (P = 0.013), and between the collected CD34+ cell counts and the pre-apheresis peripheral blood (PB) CD34+ cell counts (P<0.001). Harvesting at least >4 x 10(6)/kg CD34+ cells from the 1st LVL was achieved in 44 (77.2%) out of 57 donors and in 19 (90.5%) out of 21 donors with a PB-CD34+ cell count of >40/microl. There was no significant difference in the harvested MNC and CD34+ cell counts between the 1st and 2nd apheresis. The catheter-related complications included catheter obstruction (n = 2) and hematoma at the insertion site (n = 3). Accordingly, LVL using femoral venous access for allogeneic PBSC collection from normal healthy donors would appear to be safe and effective.

    To evaluate the effect of mannitol injection into the rabbit ear vein by intravenous catheter on endothelial cells apoptosis, thrombus formation, the expression of plasma tissue factor (TF) and von Willebrand factor (vWF). Sixty-four Zealand rabbits were randomly divided into experiment and control group and received 20% mannitol or normal saline via ear margin veins, respectively. Both groups were injected daily. On days 1, 3, 5, and 7 after catheterization, rabbits were subjected to intraperitoneal anesthesia and their ear veins were isolated and then subjected to hematoxylin and eosin staining. Cell apoptosis was evaluated using TUNEL (terminal deoxynucleotide transferase mediated d-UTP nick end labeling) staining, and the levels of TF and vWF were analyzed by enzyme-linked immunosorbent assay. Compared with the control group, the experiment group showed significantly increased thrombus formation (p < 0.05), and a significant higher rate of apoptosis in endothelial cells (p < 0.05) on days 3, 5, and 7. In addition, the experiment group showed significant elevation of plasma TF and vWF on days 3, 5, and 7 (p < 0.05). Continuous mannitol injection by intravenous catheterization induces more serious venous thrombus formation and endothelial cells apoptosis and higher TF and vWF levels than normal saline injection. These data suggest that clinical use of hyperosmotic mannitol by intravenous catheter may exert direct deleterious effects on vascular endothelium.

    ABSTRACT Objective To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Methods Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. Results In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Conclusion Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others. PMID:28076593

    Bacteraemia associated with indwelling central venous catheters (CVC) causes significant morbidity in children with cancer. Hydrochloric acid (HCl) instillations have been reported to salvage CVCs with antibiotic-refractory infection. We implemented this treatment in 2002. The impact on the survival of CVCs has been evaluated in a retrospective cohort study of children with acute lymphoblastic leukaemia (ALL). Children with newly diagnosed ALL during 1999-2005 having their first CVC inserted before (n = 16) and after (n = 24) the introduction of the procedure were studied. All bacteraemic episodes were reviewed, recording bacteriological findings and treatment, and the time to premature or planned removal of the CVC was determined. In the comparison cohort, 31.0% (9/29) of bacteraemic episodes led to removal of the CVC, compared to 5.5% (2/36) in the intervention cohort (p = 0.01). Thus, the rate of catheter loss due to infection fell from 56.3% (9/16) to 8.3% (2/24) after introducing HCl treatment (p = 0.0025). Overall, the premature catheter removal rate fell from 75.0% (12/16) to 45.8% (11/24) (p = 0.10). Analysed in a CUSUM plot the reduced frequency of premature CVC removal evidently coincided with the introduction of the procedure. In a subgroup analysis of 21 monobacterial infections with coagulase-negative staphylococci, a decrease in systemic and lock antibiotic therapy was found. No adverse events were noted. HCl instillations significantly reduced the need to remove and replace CVCs. The procedure is practical, appears to be safe, and may reduce the consumption of antibiotics.

    To facilitate therapy of central venous catheter-related Gram-positive bacterial infection in patients who require total parenteral nutrition (TPN) therapy, we studied the stability of vancomycin in a commonly used TPN solution (V-TPN) at final concentrations of 0.5 mg/mL and 1.0 mg/mL and in heparin (100 U/mL in 0.9% NaCl) at 25 micrograms/mL (V-H). Vancomycin concentrations in V-TPN and V-H after storage at 4 degrees C over 35 and 14 days, respectively, were stable (within 10% of the prestorage vancomycin concentration). After 14 days at 4 degrees C heparin activity in V-H solution was 100 +/- 4% of that noted initially. Vancomycin remained stable (100 +/- 6% of the original vancomycin concentration) when the previously refrigerated V-TPN was held for an additional 24 hours at 22 degrees C. When the previously refrigerated V-H was held for an additional 24 hours at 37 degrees C, vancomycin concentrations decreased to 78 +/- 9% of the baseline concentrations (p less than .001). The stability of vancomycin in this TPN solution allows the daily dose of vancomycin to be mixed with the solution and then infused over 10 hours. As shown with pharmacokinetic modeling, this form of therapy will achieve serum vancomycin concentrations within the therapeutic range throughout a 24-hour period. The relative stability of vancomycin in a heparin line-flush solution allows vancomycin concentration in the lumen of the catheter to be maintained at greater than or equal to 15 micrograms/mL during the interval between catheter flushing and the subsequent TPN infusion. A simplified method of administering vancomycin to patients receiving concurrent TPN is possible.

    Bilateral total knee replacement (BTKR) has been associated with a higher incidence of fat embolism (FES) compared to single knee replacement. Consequently, intraoperative monitoring with a pulmonary artery catheter (PAC) has been recommended. This study compares clinical outcome in BTKR patients monitored with central venous pressure versus PAC. A retrospective chart review of 249 consecutive patients undergoing BTKR, 132 of whom had PAC insertion versus 117 who had central line insertion, over a 1-year period were included in the study. Their medical records were reviewed for co-morbidities, baseline characteristics, and type of intraoperative monitoring. Need and duration for postoperative monitoring in the postoperative care, length of hospital stay (LOHS), signs of fat embolism, development of arrhythmias, and respiratory failure were all outcome measures. A total of four patients (1.6%) had FES as per Schonfeld criteria. One of these patients died within 48 h of surgery. They all had PAC monitoring intraoperatively. Pulmonary artery pressure (PAP) remained unchanged during surgery which raises doubt as to the clinical utility and advisability of the use of PAC’s in this setting. There was no statistically significant difference in cardiac or pulmonary complications, or LOHS between the two groups. Central venous pressure monitoring appears to be sufficient in patients undergoing BTKR. PMID:19002531

    Central venous catheter (CVC) insertions are increasingly performed in surgical patients and intensive therapy. A simple and invasive procedure performed under strict sterile precautions with complications ranging from arrhythmias; infections; and life-threatening complications such as pericardial tamponade, cardiac perforation and even death. A post-procedure chest X-ray (CXR), though does not accurately assess the tip of the catheter in relation to the superior vena cava (SVC) and right atrium (RA), can detect malpositions, safety of catheter tip, pneumothorax and kinking. We would like to share some of the malpositions we encountered in our centre, their management and a brief review of the literature on optimal catheter tip location. PMID:24106371

    We describe the effect of simulation-based education on residents' adherence to protocols for and performance of central venous access. Internal medicine and emergency medicine residents underwent a central venous access course that included a lecture, video presentation, readings, and simulation demonstrations presented by faculty. Baseline data were collected before the course was initiated. After a skills session where they rehearsed their ultrasound-guided central venous access skills, residents were evaluated using a procedural checklist and written knowledge exam. Residents also completed questionnaires regarding confidence in performing ultrasound-guided central venous access and opinions about the training course. Residents demonstrated significant improvement on the written knowledge exam (P < 0.0001) and Standard Protocol Checklist (P < 0.0001) after the training course. Training improved a number of patient safety elements, including adherence to sterile technique, transparent dressing, discarding sharps, and ordering postprocedure x-rays. However, a number of residents failed to wash their hands, prepare with chlorhexidine, drape the patient using a sterile technique, anesthetize the site, and perform a preprocedure time-out. Significant improvement in procedural skills was also noted for reduction in skin-to-vein time (P < 0.003) as well as a reduction in number of residents who punctured the carotid artery (P < 0.02). Simulation-based education significantly improved residents' knowledge and procedural skills along with their confidence. Adherence to the protocol also improved. This study illustrates that simulation-based education can improve patient safety through training and protocols.

    Central line-associated bloodstream infection (CLABSIs) is an important healthcare-associated infection in the critical care units. It causes substantial morbidity, mortality and incurs high costs. The use of central venous line (CVL) insertion bundle has been shown to decrease the incidence of CLABSIs. Our aim was to study the impact of CVL insertion bundle on incidence of CLABSI and study the causative microbial agents in an intensive care unit in Kuwait. Surveillance for CLABSI was conducted by trained infection control team using National Health Safety Network (NHSN) case definitions and device days measurement methods. During the intervention period, nursing staff used central line care bundle consisting of (1) hand hygiene by inserter (2) maximal barrier precautions upon insertion by the physician inserting the catheter and sterile drape from head to toe to the patient (3) use of a 2% chlorohexidine gluconate (CHG) in 70% ethanol scrub for the insertion site (4) optimum catheter site selection. (5) Examination of the daily necessity of the central line. During the pre-intervention period, there were 5367 documented catheter-days and 80 CLABSIs, for an incidence density of 14.9 CLABSIs per 1000 catheter-days. After implementation of the interventions, there were 5052 catheter-days and 56 CLABSIs, for an incidence density of 11.08 per 1000 catheter-days. The reduction in the CLABSI/1000 catheter days was not statistically significant (P=0.0859). This study demonstrates that implementation of a central venous catheter post-insertion care bundle was associated with a reduction in CLABSI in an intensive care area setting.

    Vasculo-Behçet's disease mainly affects the venous system and central or peripheral arteries. It is often difficult to diagnosis this due to the complexity of symptoms and the rarity. A 35-year-old man with refractory inguinal lymphadenitis was admitted to our hospital. He was diagnosed with left femoral arterial pseudoaneurysm by enhanced CT scan of the lower legs, and we performed an emergency operation. Seven months postoperatively, he suddenly developed deep venous thrombosis, and then, symptoms such as aphthous stomatitis and pudendal ulcer started to develop progressively, complicating his uveitis. Finally, he was diagnosed with vasculo-Behçet's disease.

    In our neonatal intensive care unit, the incidence density of infections related to central catheters, assessed retrospectively over 2 years, exceeded that described in the literature. To reduce this incidence density, clinical practice guidelines were implemented for the insertion and maintenance of central lines. The purpose of this study was to evaluate the impact of the protocol on the incidence density and the incidence rate of nosocomial bloodborne infections. This was a prospective study in a neonatal intensive care unit of the Fort-de-France University Hospital over 17 months, which included all premature infants with a central line. We studied the adherence to the protocol, possible complications related to the protocol, the characteristics of the population, the incidence rate, and the density of specific central catheter-related infections. There were 111 children, 122 catheters, and 2575 catheter days during period 1 and 101 children, 125 catheters, and 1631 catheter days during period 2. Gestational age and birth weight were significantly lower in period 2 (29.6±2.3 GW vs 27.3±1.9, P=0.001; 1239±379g vs 915±175g, P<0.001) and the catheterization duration differed between the 2 periods (20±11 days vs 13±6 days, P<0.0001). A trend for a lower incidence density of infection was observed in the second period (16 per 1000 catheter days vs 10 per 1000 catheter days, P=0.06). Although the 2 groups' baseline characteristics were different, this study suggests a positive impact of clinical practice guidelines for the insertion and maintenance of central venous catheters on the incidence of nosocomial infections related to central catheters.

    Many procedures in minipigs require establishment of reliable deep venous access with a large-bore catheter. In animal experiments, such catheters are typically implanted surgically. In clinical settings, however, ultrasound imaging is routinely used to facilitate safe, minimally invasive puncture of deep vessels. The authors describe a technique for using ultrasound guidance to puncture and cannulate the minipig femoral vein. They carried out the procedure in six minipigs for the purpose of injecting contrast agents for subsequent imaging scans. The procedure was ultimately successful in all pigs, took 10 min on average and resulted in no physiological complications. In one minipig, however, a 10-cm-long catheter became dislodged from the femoral vein; use of a longer (25-cm-long) catheter was optimal for establishing reliable intravenous access.

    In cancer patients with long-term central venous catheters (CVC), removal and reinsertion of a new CVC at a different site might be difficult because of the unavailability of accessible vascular sites. In vitro and animal studies showed that a minocycline-EDTA-ethanol (M-EDTA-EtOH) lock solution may eradicate microbial organisms in biofilms, hence enabling the treatment of central line-associated bloodstream infections (CLABSI) while retaining the catheter in situ Between April 2013 and July 2014, we enrolled 30 patients with CLABSI in a prospective study and compared them to a historical group of 60 patients with CLABSI who had their CVC removed and a new CVC inserted. Each catheter lumen was locked with an M-EDTA-EtOH solution for 2 h administered once daily, for a total of 7 doses. Patients who received locks had clinical characteristics that were comparable to those of the control group. The times to fever resolution and microbiological eradication were similar in the two groups. Patients with the lock intervention received a shorter duration of systemic antibiotic therapy than that of the control patients (median, 11 days versus 16 days, respectively; P < 0.0001), and they were able to retain their CVCs for a median of 74 days after the onset of bacteremia. The M-EDTA-EtOH lock was associated with a significantly decreased rate of mechanical and infectious complications compared to that of the CVC removal/reinsertion group, who received a longer duration of systemic antimicrobial therapy.

    Peripherally inserted central venous catheters (PICCs) are now commonly used for central access in the intensive care unit (ICU) setting; however, there is a paucity of data evaluating the complication rates associated with these lines. We performed a retrospective review of all PICCs placed in the inpatient setting at our institution during a 1-year period from January 2013 to December 2013. These were divided into two groups: those placed at the bedside in the ICU and those placed by interventional radiology in non-ICU patients. Data regarding infectious and thrombotic complications were collected and evaluated. During the study period, 1209 PICC line placements met inclusion criteria and were evaluated; 1038 were placed by interventional radiology in non-ICU patients, and 171 were placed at the bedside in ICU patients. The combined thrombotic and central line associated blood stream infection rate was 6.17 per cent in the non-ICU group and 10.53 per cent in the ICU group (P = 0.035). The thrombotic complication rate was 5.88 per cent in the non-ICU group and 7.60 per cent in the ICU group (P = 0.38), whereas the central line associated blood stream infection rate was 0.29 per cent in the non-ICU group and 2.92 per cent in the ICU group (P = 0.002). This study seems to suggest that PICC lines placed at the bedside in the ICU setting are associated with higher complication rates, in particular infectious complications, than those placed by interventional radiology in non-ICU patients. The routine placement of PICC lines in the ICU settings needs to be reevaluated given these findings.

    The concentrations of cocaine and its major metabolite benzoylecgonine (BZE) were determined in femoral blood from 132 cocaine-related deaths and compared with venous blood from 988 apprehended drivers. Cocaine and BZE were determined by solid-phase extraction and isotope dilution gas chromatography-mass spectrometry with limits of quantitation of 0.02 mg/L for both substances. Significantly more men (95-98%) than women (2-5%) abused cocaine, although their mean age was about the same (29-30 years). Mean age (±SD) of cocaine-related deaths was 29 ± 7 years, which was not significantly different from 30 ± 8 years in traffic cases (P > 0.05). The median concentration of cocaine in blood in 61 fatalities was 0.10 mg/L compared with 0.06 mg/L in traffic cases (P < 0.001). In drug intoxication deaths, the median concentration of cocaine was 0.13 mg/L (N = 25), which was not significantly different from 0.09 mg/L (N = 36) in other causes of death. Cocaine-related deaths mostly involved mixed drug intoxications including co-ingestion of heroin, cannabis, amphetamines as well as legal drugs, such as benzodiazepines and/or ethanol. The concentrations of cocaine in blood from living and deceased persons overlapped, which makes it infeasible to predict toxicity from the analytical toxicology results alone.

    Our objective was to compare mortality, epidemiology, and morbidity in hospitalized patients with candidemia which was both related and unrelated to the central venous catheter (CVC). This was a monocentric, retrospective cohort study of candidemia. The sample consisted of 103 patients with laboratory-confirmed nosocomial candidemia hospitalized between 2006 and 2013 in a tertiary care public hospital. We included 65 (63.1 %) patients (24 in the CVC-positive group, 41 in the CVC-negative group). Demographic data and risk factors were recorded using a structured case report form. In the group of candidemia associated to the CVC, survival at day 50 was 58.6 ± 11.9 %, compared to 26.5 ± 8.9 % for the CVC-negative group (p-value = 0.012); the hazard ratio of death was 0.38 (95 % confidence interval 0.17-0.85, p-value = 0.019). Compared with the CVC-positive patients, CVC-negative patients were often colonized with yeast (41.5 % vs. 16.7 %, p-value = 0.041), had a shorter previous in-hospital stay (20 days vs. 34 days, p-value = 0.023), and were more severely ill (severe sepsis 85.4 % vs. 58.3 %, p-value = 0.016). In this study, when the origin of candidemia was not the CVC, patients were more seriously ill, had a higher mortality rate, and the removal of the catheter seemed to lead to disappointing results. It would be useful to explore the impact of retention of the CVC on survival in the CVC-negative patients, where the CVCs are essential to treating these patients.

    BACKGROUND Patients are frequently discharged with central venous catheters (CVCs) for home infusion therapy. OBJECTIVE To study a prospective cohort of patients receiving home infusion therapy to identify environmental and other risk factors for complications. DESIGN Prospective cohort study between March and December 2015. SETTING Home infusion therapy after discharge from academic medical centers. PARTICIPANTS Of 368 eligible patients discharged from 2 academic hospitals to home with peripherally inserted central catheters and tunneled CVCs, 222 consented. Patients remained in the study until 30 days after CVC removal. METHODS Patients underwent chart abstraction and monthly telephone surveys while the CVC was in place, focusing on complications and environmental exposures. Multivariable analyses estimated adjusted odds ratios and adjusted incident rate ratios between clinical, demographic, and environmental risk factors and 30-day readmissions or CVC complications. RESULTS Of 222 patients, total parenteral nutrition was associated with increased 30-day readmissions (adjusted odds ratio, 4.80 [95% CI, 1.51-15.21) and CVC complications (adjusted odds ratio, 2.41 [95% CI, 1.09-5.33]). Exposure to soil through gardening or yard work was associated with a decreased likelihood of readmissions (adjusted odds ratio, 0.09 [95% CI, 0.01-0.74]). Other environmental exposures were not associated with CVC complications. CONCLUSIONS complications and readmissions were common and associated with the use of total parenteral nutrition. Common environmental exposures (well water, cooking with raw meat, or pets) did not increase the rate of CVC complications, whereas soil exposures were associated with decreased readmissions. Interventions to decrease home CVC complications should focus on total parenteral nutrition patients. Infect Control Hosp Epidemiol 2016;1-8.

    Although peripheral venous catheter (PVC) placement is one of the most common invasive procedures used in hospitals, data about the infectious risk associated with it are sparse. Nurses and physicians often underestimate this risk. We describe here a 10-year continuous quality improvement program in a large university hospital. The prevention program included: 1/ an observational audit of practices of PVC insertion and maintenance (1996), 2/ two studies of incidence and risk factors for PVC-related infection (1996 and 1999), 3/ 8 annual (1996 to 2006) cross-sectional studies that collected information about duration of PVC placement and other process indicators, 4/ surveillance of nosocomial bacteremia from 2002 through 2006, and 5/ continued education sessions for healthcare workers, based on local surveillance data. Rates of colonization and infection (0.7 cases of bacteremia/1000 PVC days) were similar to data from other studies. PVC that remained in place for more than three days was associated with a higher risk of catheter-related bacteremia in both incidence studies. The annual prevalence studies showed that 15 to 20% of PVCs remained in place for more than three days from 1996 through 2002, but this rate decreased thereafter; it was 6.7% in 2005 and 10.7% in 2006. Practices audits indicated room for improvement in prevention measures. The absolute number of PVC-related bacteremia decreased by more than 50% from 2002 (n=23) to 2006 (n=10). This prolonged multifaceted program, including practice audits, continued medical education and monitoring of PVC-related infection, has led to a substantial decrease over time in the infectious risk related to PVC placement.

    Although the use of central venous catheters (CVCs) has greatly improved the quality of care of children with cancer, these catheters increase the risk of deep vein thrombosis (DVT) and the potential long-term complication of post-thrombotic syndrome (PTS). We aimed to study PTS post-CVC removal using physical, functional and health related quality of life (HRQoL) domains in childhood cancer and bone marrow transplantation (BMT) survivors. We conducted a prospective study in a cohort of childhood cancer and BMT survivors post-CVC use. Participants were evaluated for PTS with the Modified Villalta Score (MVS) and the Manco-Johnson Instrument (MJI). HRQoL was assessed using the PedsQL™ questionnaire. A total of 158 children were enrolled at a median of 41 (4-149) months from CVC removal. Signs and symptoms of PTS were present in 34% (95% confidence interval [CI] 27-43%) (MVS criteria) and 30.5% (95% CI 23.1-37.8%) (MJI criteria). Diagnosis of PTS was associated with history of CVC occlusion, history of CVC-related DVT and the use of ≥2 CVCs. The presence of signs and symptoms of PTS was a predictor for low HRQoL tested by the PedsQL™ Total Scale scores and Physical Health Summary scores. PTS post-CVC removal in pediatric cancer survivors is not a rare event. The association between PTS and the history of CVC occlusion confirms earlier findings, and suggests that CVC occlusion may indicate asymptomatic DVT. PTS is also associated with lower HRQoL scores highlighting the need to study preventive measures, especially for high risk groups.

    Introduction Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to identify practice-mirroring risk factors. Methods A prospective observational study was conducted as a part of a research project, called CATHEVAL, in one surgery ward and four medicine wards from three public general tertiary care hospitals in Northern France that were invited to participate between June-2013 and June-2014. Each participating ward included during a two-month study period all patients older than 15 years carrying a PVC. All inserted PVCs were monitored from insertion of PVC to up to 48 hours after removal. Monitored data included several practice-mirroring items, as well as the occurrence of at least one PVCAE. A multivariate Cox proportional hazard model, based on a marginal risk approach, was used to identify factors associated with the occurrence of at least one PVCAE. Results Data were analysed for 815 PVCs (1964 PVC-days) in 573 patients. The incidence of PVCAE was 52.3/100 PVCs (21.9/100 PVC-days). PVCAEs were mainly clinical: phlebitis (20.1/100 PVCs), haematoma (17.7/100 PVCs) and liquid/blood escape (13.1/100 PVCs). Infections accounted for only 0.4/100 PVCs. The most frequent mechanical PVCAEs, was obstruction/occlusion of PVC (12.4/100 PVCs). The incidence of post-removal PVCAEs was 21.7/100 PVCs. Unstable PVC and unclean dressing were the two main risk factors. Conclusion Limitation of breaches in healthcare quality including post-removal monitoring should be reinforced to prevent PVC-related adverse events in hospital settings. PMID:28045921

    Catheter-related infections (CRI) cause considerable morbidity in hospitalized patients. The incidence does not seem to be higher in neutropenic patients than in nonneutropenic patients. Gram-positive bacteria (coagulase-negative staphylococci, Staphylococcus aureus) are the pathogens most frequently cultured, followed by Candida species. Positive blood cultures are the cornerstone in the diagnosis of CRIs, while local signs of infection are not necessarily present. Blood cultures should be taken from peripheral blood and from the venous catheter. A shorter time to positivity of catheter blood cultures as compared with peripheral blood cultures supports the diagnosis of a CRI. In many cases, a definite diagnosis requires catheter removal and microbiological analysis. The role plate method with semiquantitative cultures has been established as standard in most laboratories. Antimicrobial treatment of CRI should be directed by the in vitro susceptibility of the isolated pathogen. Primary removal of the catheter is mandatory in S. aureus and Candida infections, as well as in case of tunnel or pocket infections. Future studies will elucidate whether the rate of CRI in neutropenic patients may be reduced by catheters impregnated with antimicrobial agents.

    Central venous catheters are routinely positioned for hemodynamic monitoring and fluid administration in patients undergoing cardiac surgery, and many well-known complications associated with this manoeuver have been described. Metalic guide wire embolization is a rare complication potentially associated with nonmechanical and mechanical adverse events. The case we report is peculiar as an almost fully endothelialized guide wire was successfully retrieved 9 months after its unintentional embolization in the inferior vena cava.

    Catheter-related bloodstream infections (CRBSIs) and catheter-related thrombosis (CRT) are common complications of central venous catheters (CVC), which are used to monitor patient health and deliver medications. CVCs are subject to protein adsorption and platelet adhesion as well as colonization by the natural skin flora (i.e. Staphylococcus aureus and Staphylococcus epidermidis). Antimicrobial and antithrombotic drugs can prevent infections and thrombosis-related complications, but have associated resistance and safety risks. Surface topographies have shown promise in limiting platelet and bacterial adhesion, so it was hypothesized that an engineered Sharklet micropattern, inspired by shark-skin, may provide a combined approach as it has wide reaching anti-fouling capabilities. To assess the feasibility for this micropattern to improve CVC-related healthcare outcomes, bacterial colonization and platelet interactions were analyzed in vitro on a material common for vascular access devices. To evaluate bacterial inhibition after simulated vascular exposure, micropatterned thermoplastic polyurethane surfaces were preconditioned with blood proteins in vitro then subjected to a bacterial challenge for 1 and 18 h. Platelet adhesion was assessed with fluorescent microscopy after incubation of the surfaces with platelet-rich plasma (PRP) supplemented with calcium. Platelet activation was further assessed by monitoring fibrin formation with fluorescent microscopy after exposure of the surfaces to platelet-rich plasma (PRP) supplemented with calcium in a flow-cell. Results are reported as percent reductions and significance is based on t-tests and ANOVA models of log reductions. All experiments were replicated at least three times. Blood and serum conditioned micropatterned surfaces reduced 18 h S. aureus and S. epidermidis colonization by 70% (p ≤ 0.05) and 71% (p < 0.01), respectively, when compared to preconditioned unpatterned controls.

    Catheter-related blood stream infection (CR-BSI) in patients with pulmonary hypertension (PH) receiving intravenous iloprost via an indwelling central line has previously not been fully described. Recent studies have suggested a link between the pH of prostanoid infusions and the rate and nature of CR-BSI. We have investigated CR-BSI in patients receiving intravenous iloprost at our unit. Databases and hospital records were interrogated for all patients receiving intravenous iloprost between September 2007 and June 2012. Fifty-nine patients received intravenous iloprost via an indwelling central catheter with a total of 23,072 treatment days. There were 15 episodes of CR-BSI, identified using a systematic screening protocol, involving 11 patients giving an overall CR-BSI rate of 0.65/1,000 treatment days. CR-BSI rate for Gram-positive organisms was 0.26/1,000 treatment-days and for Gram-negative organisms was 0.39/1,000 treatment-days. The pH of iloprost in typical dosing regimens was comparable to the pH used in standard-diluent treprostinil and dissimilar to alkaline epoprostenol infusions. The proportion of Gram-negative CR-BSI was similar to that reported for standard-diluent treprostinil. CRP was normal on admission in 33 % of cases of confirmed CR-BSI and remained normal in 13 % of cases. CR-BSI rates with intravenous iloprost are comparable to those observed for other prostanoids. The high proportion of Gram-negative organisms observed and the neutral pH of iloprost infusions support the previously hypothesised link between pH and antimicrobial activity. Although usually elevated during a CR-BSI, CRP may be normal in early infection and a normal result cannot completely exclude infection.

    Normal hematologic values for African green monkeys have been reported, but these results are confounded by the effect of chemical restraint (for example, ketamine), physical restraint, and capture stress. The dual-lumen central venous catheter, jacket, and tether combination we describe here allows intravenous fluid administration and repeated blood sampling without the use of anesthesia or inducing capture-related stress. The use of a low-concentration heparin solution for catheter maintenance significantly increased the mean patency time, compared with a saline-only catheter flush solution. Adding a low-concentration heparin solution creates a suitable system for serial blood collection in the African green monkey for as long as 25 d.

    Different pericardial catheters have been suggested as an effective alternative method for drainage of pericardial effusion. The aim of this study was to determine the performance, pain, and quality of life on use of central venous catheter (CVC) for drainage of pericardial effusion in patients undergoing open heart surgery. Fifty-five patients who had developed pericardial effusion after an open heart surgery (2012–2015) were prospectively assessed. Triple-lumen central catheters were inserted under echocardiographic guidance. Clinical, procedural, complication, and outcome details were analyzed. Intensity of pain and quality of life of patients were assessed using the numerical rating scale and Short-Form Health Survey. CVC was inserted for 36 males and 19 females, all of whom had a mean age of 58.5±15 years, and the mean duration of the open heart surgery was 8±3.5 hours. The mean central venous pressure catheter life span was 14.6 days. No cases of recurrent effusion and complication were reported. The technical success rate of procedure was 100%. Intensity of pain and quality of life of patients had improved during follow-up. CVC insertion is a safe and effective technique for the management of pericardial effusion in patients after open heart surgery. PMID:27826210

    Central venous cannulation is a commonly performed procedure which facilitates resuscitation, nutritional support, and long-term vascular access. Mechanical complications most often occur during insertion and are intimately related to the anatomic relationship of the central veins. Working knowledge of surface and deep anatomy minimizes complications. Use of surface anatomic landmarks to orient the deep course of cannulating needle tracts appropriately comprises the crux of complication avoidance. The authors describe use of surface landmarks to facilitate safe placement of internal jugular, subclavian, and
