[Postoperative spine].  

PubMed

Approximately 15-30?% of surgical procedures involving the lumbar spine are associated with complications that require further diagnostic work-up. The choice of imaging modality for postoperative complications depends on the extent, pattern and temporal evolution of the postoperative neurological signs and symptoms as well as on the preoperative clinical status, the surgical procedure itself and the underlying pathology. The interpretation of imaging findings, in particular the distinction between postoperative complications and normally expected nonspecific postoperative imaging alterations can be challenging and requires the integration of clinical neurological information and the results of laboratory tests. The combination of different imaging techniques might help in cases of equivocal imaging results. PMID:25398572

Postoperative fatigue  

Microsoft Academic Search

Uncomplicated major surgery is followed by a pronounced increased feeling of fatigue extending throughout the first month in about one-third of patients. Postoperative fatigue correlates with the degree of surgical trauma but is not related to duration of general anesthesia and surgery or to preoperative nutritional status, age, or sex. Fatigue also correlates with postoperative deterioration in nutritional parameters and

Postoperative Delirium  

PubMed Central

Delirium (acute confusion) complicates 15% to 50% of major operations in older adults and is associated with other major postoperative complications, prolonged length of stay, poor functional recovery, institutionalization, dementia, and death. Importantly, delirium may be predictable and preventable through proactive intervention. Yet clinicians fail to recognize and address postoperative delirium in up to 80% of cases. Using the case of Ms R, a 76-year-old woman who developed delirium first after colectomy with complications and again after routine surgery, the diagnosis, prevention, and treatment of delirium in the postoperative setting is reviewed. The risk of postoperative delirium can be quantified by the sum of predisposing and precipitating factors. Successful strategies for prevention and treatment of delirium include proactive multifactorial intervention targeted to reversible risk factors, limiting use of sedating medications (especially benzodiazepines), effective management of postoperative pain, and, perhaps, judicious use of antipsychotics.

Postoperative pain management  

PubMed Central

Postoperative pain is a very important issue for several patients. Indifferent of the surgery type or method, pain management is very necessary. The relief from suffering leads to early mobilization, less hospital stay, reduced hospital costs, and increased patient satisfaction. An individual approach should be applied for pain control, rather than a fix dose or drugs. Additionally, medical, psychological, and physical condition, age, level of fear or anxiety, surgical procedure, personal preference, and response to agents given should be taken into account. The major goal in the management of postoperative pain is minimizing the dose of medications to lessen side effects while still providing adequate analgesia. Again a multidisciplinary team approach should be pursued planning and formulating a plan for pain relief, particularly in complicated patients, such as those who have medical comorbidities. These patients might appear increase for analgesia-related complications or side effects. PMID:25774311

[Smoking in postoperative period].  

PubMed

Smokers have an elevated risk of perioperative respiratory distress and of transfer to intensive care. Tobacco smoke substantially alters the healing process and constitutes a documented risk factor for postoperative complications (anastomotic leakage, delayed healing etc.). Risk of postoperative infection is also higher in smokers. When patients stop smoking 6 to 8 weeks before surgery, the incidence of complications related to tobacco smoke drops nearly to zero. Even stopping for a short period reduces the risk of complications, although the benefits of stopping increase with length of time. Preoperative smoking cessation should take place as early as possible. The general practitioner and the surgeon both have essential roles to play. Identification of smokers must be accompanied by measures to help the patient stop smoking, including advice, and if necessary, nicotine substitutes. Anxiety levels are higher in smokers than nonsmokers. Nonetheless smoking cessation for hospitalization does not increase these levels, even without nicotine substitutes. There is no interaction between anesthetic agents and nicotine substitutes: the latter may be continued through the morning of surgery and reinitiated in the immediate postoperative period. Patients who stop smoking for surgery should be encouraged to continue to stop, permanently. The general practitioner's support is essential for this. PMID:16783265

Postoperative cerebral venous infarction  

PubMed Central

Background: Postoperative cerebral venous infarction (POCVI) is not an uncommon complication in cranial surgeries. However, literature is sparse on the epidemiology and management of postoperative venous infarcts. Aims and Objectives: The aim was to study the incidence and clinico-radiological course of POCVI in patients in a tertiary level neurosurgical unit and compare the outcome between pediatric and adult patients following POCVI. Materials and Methods: In this prospective study carried out over an 8 month period, consecutive patients undergoing elective major cranial surgeries were monitored neurologically and with serial computed tomography (CT) of the head for POCVI in the postoperative period. All patients had at least one CT head done within 24 hours of surgery. Diagnosis of hemorrhagic POCVI was based on the presence of subcortical, multifocal hyperdensities with irregular margins and or low density areas in the perioperative fields. Nonhemorrhagic POCVI was diagnosed if CT showed a localized hypodensity poorly demarcated in the subcortical white matter with/without mass effect, along with the presence of fresh neurological deficits. Observations and Results: A total of 376 patients were enrolled in the study period. Of these, 26 (7%) developed POCVI. The male: female ratio was 1.2:1 and age ranged from 6 to 68 years with 12 (46%) being under the age of 18 years. Sixteen (61%) patients developed hemorrhagic POCVI and 10 (39%) patients developed nonhemorrhagic POCVI. The mean time to POCVI detection was 72 hours (range 24–144 hours). Seventeen (66%) patients were managed conservatively, and nine (34%) patients underwent decompressive craniectomy as an additional procedure for management of POCVI. In five patients (all with hemorrhagic POCVI), the infarction was an incidental finding. Of the 21 patients with symptomatic POCVI, 13 (61.9%) patients improved neurologically and were discharged with residual deficits. Two (9.5%) showed no neurological improvement till discharge, and 6 (28.5%) died during the hospital stay following POCVI. Conclusions: Children constitute a significant population (46% in our study) of the patients who develop POCVI with poor outcome similar to that seen in adult patients.

Postoperative nausea and vomiting  

PubMed Central

Postoperative nausea and vomiting (PONV) is a long-standing issue, not a new concept in anesthesiology. Despite many studies over the last several decades, PONV remains a significant problem due to its complex mechanism. This review presents a summary of the mechanism underlying the pathogenesis of PONV, focusing on preventive treatment, particularly the use of new drugs. In addition, we discuss the latest meta-analysis results regarding correct clinical use of classic drugs. I also summarize the latest trends of postdischarge nausea and vomiting and the pharmacogenetics, which is attracting a great deal of attention from other medical fields in PONV-related studies. Finally, we discuss the drawbacks of existing studies on PONV and suggest a focus for future investigations. PMID:25302092

Has postoperative pain been eradicated?  

PubMed Central

Recent evidence suggests that surgical trauma induces a process of central nervous system sensitisation that contributes to and enhances postoperative pain. These changes are also thought to be the underlying cause of much chronic pain. Central sensitisation is generated not only during surgery, but also postoperatively as a result of the inflammatory response to the damaged tissue. This knowledge provides a rational basis for pro-active, pre-emptive and postoperative analgesic strategies to reduce the neuronal barrage associated with tissue damage. Reduction or elimination of postoperative pain is therefore possible. We advocate the use of continuous extrapleural intercostal nerve block for postoperative analgesia in patients undergoing thoracotomy. When this is begun pre-emptively (by precutaneous, pre-incisional paravertebral block) it is combined with an opiate and a non-steroidal anti-inflammatory drug premedication. In a randomised study of 56 patients, pain scores of less than 0.5 cm on a 10 cm scale were produced, postoperative lung function was preserved and glucose and cortisol responses were significantly unchanged from preoperative values. Evidence that effective perioperative analgesia reduces the incidence of chronic post-thoracotomy chest wall pain was found in a retrospective study of 1000 consecutive thoracotomies. The endpoints of a zero pain score, complete preservation of preoperative lung function and prevention of the stress response to trauma are currently achievable and should be provided for virtually all patients undergoing chest surgery. Pre-empting pain must be the goal for all those involved in the postoperative care of patients. Images Figure 2 Figure 3 Figure 4 PMID:7598419

Cognitive Trajectories after Postoperative Delirium  

PubMed Central

BACKGROUND Delirium is common after cardiac surgery and may be associated with long-term changes in cognitive function. We examined postoperative delirium and the cognitive trajectory during the first year after cardiac surgery. METHODS We enrolled 225 patients 60 years of age or older who were planning to undergo coronary-artery bypass grafting or valve replacement. Patients were assessed preoperatively, daily during hospitalization beginning on postoperative day 2, and at 1, 6, and 12 months after surgery. Cognitive function was assessed with the use of the Mini–Mental State Examination (MMSE; score range, 0 to 30, with lower scores indicating poorer performance). Delirium was diagnosed with the use of the Confusion Assessment Method. We examined performance on the MMSE in the first year after surgery, controlling for demographic characteristics, coexisting conditions, hospital, and surgery type. RESULTS The 103 participants (46%) in whom delirium developed postoperatively had lower pre-operative mean MMSE scores than those in whom delirium did not develop (25.8 vs. 26.9, P<0.001). In adjusted models, those with delirium had a larger drop in cognitive function (as measured by the MMSE score) 2 days after surgery than did those without delirium (7.7 points vs. 2.1, P<0.001) and had significantly lower postoperative cognitive function than those without delirium, both at 1 month (mean MMSE score, 24.1 vs. 27.4; P<0.001) and at 1 year (25.2 vs. 27.2, P<0.001) after surgery. With adjustment for baseline differences, the between-group difference in mean MMSE scores was significant 30 days after surgery (P<0.001) but not at 6 or 12 months (P = 0.056 for both). A higher percentage of patients with delirium than those without delirium had not returned to their preoperative baseline level at 6 months (40% vs. 24%, P = 0.01), but the difference was not significant at 12 months (31% vs. 20%, P = 0.055). CONCLUSIONS Delirium is associated with a significant decline in cognitive ability during the first year after cardiac surgery, with a trajectory characterized by an initial decline and prolonged impairment.

Datenschutzängste, verbunden mit politischen Vorgängen (Friedensbewegung), erregten die Menschen, und das Bundesverfassungsgericht steckte neue Grenzen ab. Nach kontroversen Auseinandersetzungen, an denen die Deutsche Statistische Gesellschaft (DStatG) konstruktiv beteiligt war, kam es zur Volkszählung 1987. Den nachfolgenden Paradigmenwechsel hin zu einem registergestützten Zensus 2011 hat die DStatG ebenfalls kreativ mitgestaltet. Im Beitrag wird dieser Weg nachgezeichnet. Das neue Konzept wird vorgestellt und kritisch gewürdigt. Betroffen war auch der Mikrozensus als größte Bevölkerungs- und Arbeitsmarktstichprobe zwischen den Zensen. Nicht zuletzt durch das Wirken eines wissenschaftlichen Beirats, dessen Mitglieder von der DStatG vorgeschlagen wurden, blieb diese Erhebung in ihrem Kern für die Zukunft erhalten.

Postoperative infections in obstetrics and gynecology.  

PubMed

Postoperative infection is the most commonly seen complication of surgery in obstetrics and gynecology. The use of antibiotic prophylaxis has greatly decreased though not completely eliminated this adverse outcome. Postoperative infections include wound cellulitis, wound abscess, endomyometritis, pelvic cellulitis, and pelvic abscess. Infections usually manifest as fever and greater than normal postoperative pain. Refractory fevers maybe because of septic pelvic vein thrombophlebitis or maybe noninfectious in origin. Broad-spectrum antibiotics should be initiated as soon as possible when diagnosis of postoperative infection is made; most patients will respond to treatment within 24 to 48 hours when appropriate antibiotics are selected.

Computed tomography of the postoperative lumbar spine  

SciTech Connect

In the postoperative patient ordinary radiographs of the spine generally add very little information, revealing the usual postoperative bone changes and often postoperative narrowing of the intervertebral space. Myelography may sometimes be informative, showing evidence of focal arachnoiditis or a focal defect at the surgical site. However, the latter finding is difficult to interpret. As experience with high-resolution CT scanning of the lumbar spine has been increasing, it is becoming apparent that this noninvasive and easily performed study can give considerably more information about the postoperative spine than any of the other current imaging methods. About 750 patients with previous lumbar laminectomies had CT scanning within a 28 month period.

[Postoperative recurrence of subdural empyema].  

PubMed

We present a case of recurrent subdural post-surgical empyema by Proprionibacterium acnes after a first drained empyema in which no microbiological diagnosis was reached. P. acnes is a gram-positive anaerobic organism which is part of the saprophytic flora of the skin and others parts of the body. However, it can cause infections, as in the central nervous system, especially post-surgical infections in which can be the second more frequent organism after Staphylococcus aureus. P. acnes grows slowly and shows better growth in liquid anaerobic media. It is usually resistant to metronidazol and sensitive to penicillin. In postoperative central nervous system infections we must take into account the possibility of this organism, process the sample properly and keep touch with the Microbiology Department.

Post-operative radiation therapy  

PubMed Central

In completely resected non-small-cell lung cancer (NSCLC) patients with pathologically involved mediastinal lymph nodes (N2), administration of adjuvant platinum-based chemotherapy is now considered the standard of care, based on level 1 evidence. The role of post-operative radiotherapy (PORT) in this group of patients remains controversial. In the PORT meta-analysis published in 1998, the conclusions were that if adjuvant radiotherapy was detrimental to patients with early-stage completely resected NSCLC, the role of PORT in the treatment of tumours with N2 involvement was unclear and further research was warranted. Recent retrospective and non-randomized studies as well as subgroup analyses of recent randomized trials evaluating adjuvant chemotherapy, provide evidence of the possible benefit of PORT in patients with mediastinal nodal involvement. The question of PORT indication is also valid for those patients with proven N2 disease who undergo neo-adjuvant chemotherapy followed by surgery. The risk of local recurrence for N2 patients varies between 20% and 60%. Based on currently available data, PORT should be discussed for fit patients with completely resected NSCLC with N2 nodal involvement, within a multidisciplinary setting, preferably after completion of adjuvant chemotherapy or after surgery if patients have had neo-adjuvant chemotherapy. There is need for new randomized evidence to reassess PORT using modern three-dimensional conformal radiation technique, with attention to normal organ sparing, particularly lung and heart, to reduce the possible additional toxicity. Randomized evidence is needed. A new large international multi-institutional randomized trial Lung ART evaluating PORT in this patient population is now underway, as well as a Chinese study comparing postoperative sequential chemotherapy followed by radiotherapy versus adjuvant chemotherapy alone.

Principles of postoperative anterior cruciate ligament rehabilitation  

PubMed Central

It is known that anterior cruciate ligament (ACL) reconstruction needs to be combined with detailed postoperative rehabilitation in order for patients to return to their pre-injury activity levels, and that the rehabilitation process is as important as the reconstruction surgery. Literature studies focus on how early in the postoperative ACL rehabilitation period rehabilitation modalities can be initiated. Despite the sheer number of studies on this topic, postoperative ACL rehabilitation protocols have not been standardized yet. Could common, “ossified” knowledge or modalities really prove themselves in the literature? Could questions such as “is postoperative brace use really necessary?”, “what are the benefits of early restoration of the range of motion (ROM)?”, “to what extent is neuromuscular electrical stimulation (NMES) effective in the protection from muscular atrophy?”, “how early can proprioception training and open chain exercises begin?”, “should strengthening training start in the immediate postoperative period?” be answered for sure? My aim is to review postoperative brace use, early ROM restoration, NMES, proprioception, open/closed chain exercises and early strengthening, which are common modalities in the very comprehensive theme of postoperative ACL rehabilitation, on the basis of several studies (Level of Evidence 1 and 2) and to present the commonly accepted ways they are presently used. Moreover, I have presented the objectives of postoperative ACL rehabilitation in tables and recent miscellaneous studies in the last chapter of the paper. PMID:25232521

Postoperative surgical complications of lymphadenohysterocolpectomy  

PubMed Central

Rationale The current standard surgical treatment for the cervix and uterine cancer is the radical hysterectomy (lymphadenohysterocolpectomy). This has the risk of intraoperative accidents and postoperative associated morbidity. Objective The purpose of this article is the evaluation and quantification of the associated complications in comparison to the postoperative morbidity which resulted after different types of radical hysterectomy. Methods and results Patients were divided according to the type of surgery performed as follows: for cervical cancer – group A- 37 classic radical hysterectomies Class III Piver - Rutledge -Smith ( PRS ), group B -208 modified radical hysterectomies Class II PRS and for uterine cancer- group C -79 extended hysterectomies with pelvic lymphadenectomy from which 17 patients with paraaortic lymphnode biopsy . All patients performed preoperative radiotherapy and 88 of them associated radiosensitization. Discussion Early complications were intra-abdominal bleeding ( 2.7% Class III PRS vs 0.48% Class II PRS), supra-aponeurotic hematoma ( 5.4% III vs 2.4% II) , dynamic ileus (2.7% III vs 0.96% II) and uro - genital fistulas (5.4% III vs 0.96% II).The late complications were the bladder dysfunction (21.6% III vs 16.35% II) , lower limb lymphedema (13.5% III vs 11.5% II), urethral strictures (10.8% III vs 4.8% II) , incisional hernias ( 8.1% III vs 7.2% II), persistent pelvic pain (18.91% III vs 7.7% II), bowel obstruction (5.4% III vs 1.4% II) and deterioration of sexual function (83.3% III vs 53.8% II). PRS class II radical hysterectomy is associated with fewer complications than PRS class III radical hysterectomy , except for the complications of lymphadenectomy . A new method that might reduce these complications is a selective lymphadenectomy represented by sentinel node biopsy . In conclusion PRS class II radical hysterectomy associated with neoadjuvant radiotherapy is a therapeutic option for the incipient stages of cervical cancer.

Management of postoperative spinal infections.  

PubMed

Postoperative surgical site infection (SSI) is a common complication after posterior lumbar spine surgery. This review details an approach to the prevention, diagnosis and treatment of SSIs. Factors contributing to the development of a SSI can be split into three categories: (1) microbiological factors; (2) factors related to the patient and their spinal pathology; and (3) factors relating to the surgical procedure. SSI is most commonly caused by Staphylococcus aureus. The virulence of the organism causing the SSI can affect its presentation. SSI can be prevented by careful adherence to aseptic technique, prophylactic antibiotics, avoiding myonecrosis by frequently releasing retractors and preoperatively optimizing modifiable patient factors. Increasing pain is commonly the only symptom of a SSI and can lead to a delay in diagnosis. C-reactive protein and magnetic resonance imaging can help establish the diagnosis. Treatment requires acquiring intra-operative cultures to guide future antibiotic therapy and surgical debridement of all necrotic tissue. A SSI can usually be adequately treated without removing spinal instrumentation. A multidisciplinary approach to SSIs is important. It is useful to involve an infectious disease specialist and use minimum serial bactericidal titers to enhance the effectiveness of antibiotic therapy. A plastic surgeon should also be involved in those cases of severe infection that require repeat debridement and delayed closure. PMID:23330073

Postoperative pain: nurses' knowledge and patients' experiences.  

PubMed

The aim of this study was to determine nurses' knowledge and attitudes regarding postoperative pain and identify postoperative patients' pain intensity experiences. The assessment and management of acute postoperative pain is important in the care of postoperative surgical patients. Inadequate relief of postoperative pain can contribute to postoperative complications such as atelectasis, deep vein thrombosis, and delayed wound healing. A pilot study with an exploratory design was conducted at a large teaching hospital in the eastern United States. The convenience samples included 31 nurses from the gastrointestinal and urologic surgical units and 14 first- and second-day adult postoperative open and laparoscopic gastrointestinal and urologic patients who received patient-controlled analgesia (PCA). The Knowledge and Attitudes Survey Regarding Pain was used to measure nurses' knowledge about pain management. The Short-Form McGill Pain Questionnaire (SF-MPQ) was used to measure patients' pain intensity. The nurses' mean score on the Knowledge and Attitudes Survey Regarding Pain was 69.3%. Patients experienced moderate pain, as indicated by the score on the SF-MPQ. There is a need to increase nurses' knowledge of pain management. PMID:24315258

[Postoperative complications in plastic surgery].  

PubMed

Plastic surgery covers a broad spectrum of diseases and conditions in the areas of reconstructive surgery, hand, burn and aesthetic surgery. Besides acquired defects or malformations an increasing number of patients are being treated for surgical or multimodal complications. In a considerable number of patients plastic and reconstructive surgery remains the only therapeutic alternative after other therapy has failed. Therefore complication management in plastic surgery is of utmost importance for a successful outcome. In addition patient expectations in the results of plastic surgery as a discipline of invention and problem solving are steadily increasing. This challenge is reflected in clinical patient management by intensive research in tissue engineering and regenerative medicine. Patients in plastic surgery are recruited from all age groups of either gender, involving traumatic and oncologic as well as congenital and aesthetic disorders. The demographics of aging, multimorbidity and obesity pose new challenges to plastic surgery. Although age over 70 years is not an independent risk factor per se for complications in plastic surgery, e.g. for complex free flap transfer, medical problems are present at a higher rate, which is to be expected in this age group. Risk factors such as alcoholism and coronary heart diseases seem to be independent predictors of perioperative complications. Therefore older patients can also benefit from plastic surgery and recurrent operations by the corresponding risk and complication management. Complication management necessitates careful patient selection, estimation of operative risks and patient-adapted selection of procedures. In addition to expertise in plastic surgery a thorough knowledge of non-surgical and surgical back-up procedures for technical incidents as well as vascular circulatory and wound healing disorders is required to deal successfully with complications in plastic surgery. This article presents these specific aspects of postoperative complication management in plastic surgery. PMID:19669715

In hoch entwickelten Industrieländern stehen laut Weltgesundheitsorganisation (WHO) Herz-Kreislauf-Erkrankungen und speziell die Koronare Herzkrankheit (KHK) an erster Stelle der Todesursachen. In Deutschland betrug die Zahl der erfassten, an KHK erkrankten Personen ohne Berücksichtigung der Dunkelziffer allein im Jahre 2001 über 473.000. Die KHK war im Jahre 2003 mit 92.673 erfassten Todesfällen immer noch die häufigste Todesursache, obgleich in Deutschland die Häufigkeit der Koronarinterventionen zur Behandlung der KHK zwischen 1984 und 2003 um fast das 80fache von 2.809 auf 221.867 Eingriffe pro Jahr gestiegen ist [1]. Neben der hohen Zahl an Todesfällen haben die betroffenen Personen durch chronische Schmerzen und eingeschränkte körperliche Leistungsfähigkeit zusätzlich eine starke Beeinträchtigung der Lebensqualität [2].In Folge dessen wird die erkrankte Person häufig zum Pflegefall was neben den gesundheitlichen Aspekten auch eine sozioökonomische Komponente in Form der fehlenden Arbeitskraft und den auftretenden Pflegekosten nach sich zieht. Die Kosten für die Behandlung der KHK in Deutschland beliefen sich im Jahre 2002 laut Statistischem Bundesamt auf rund 6,9 Mrd. €. Verglichen mit ähnlichen Zahlen der USA dürfte sich der entstandene Schaden für die deutsche Volkswirtschaft im zwei- bis dreistelligen Milliardenbereich bewegen [3].

Early postoperative feeding with elemental diet.  

PubMed Central

The value of early postoperative feeding with an elemental diet was assessed in 30 patients after major gastrointestinal operations. The patients were allocated at random to conventional treatment (control group) or feeding with the elemental diet (ED group). The clinical and metabolic course of the 15 patients in the ED group was significantly better than that of the controls. Patients in the ED group lost less weight and had a shorter stay in hospital. Negative nitrogen balance was more pronounced in the control group throughout the seven postoperative days. Energy intake was higher in the ED group. Provided elemental feeding is used with caution, it may be given from the first postoperative day. Patients do better metabolically and require shorter stays in hospital. PMID:105777

Recent Advances in Postoperative Pain Management  

PubMed Central

Good pain control after surgery is important to prevent negative outcomes such as tachycardia, hypertension, myocardial ischemia, decrease in alveolar ventilation, and poor wound healing. Exacerbations of acute pain can lead to neural sensitization and release of mediators both peripherally and centrally. Clinical wind up occurs from the processes of N-Methyl D-Aspartate (NMDA) activation, wind up central sensitization, long-term potentiation of pain (LTP), and transcription-dependent sensitization. Advances in the knowledge of molecular mechanisms have led to the development of multimodal analgesia and new pharmaceutical products to treat postoperative pain. The new pharmacological products to treat postoperative pain include extended-release epidural morphine and analgesic adjuvants such as capsaicin, ketamine, gabapentin, pregabalin dexmetomidine, and tapentadol. Newer postoperative patient-controlled analgesia (PCA) in modes such as intranasal, regional, transdermal, and pulmonary presents another interesting avenue of development. PMID:20351978

Gabapentin in Acute Postoperative Pain Management  

PubMed Central

Gabapentin (1-aminomethyl-cyclohexaneacetic acid) is an amino acid that has the structure of the neurotransmitter ?-aminobutyric acid (GABA). It is a novel drug used for the treatment of postoperative pain with antihyperalgesic properties and a unique mechanism of action. Gabapentin and the related, more potent compound pregabalin have been shown to be beneficial in the treatment of neuropathic pain as well as postoperative pain following spinal surgery and hysterectomy. This study reviews five aspects of gabapentin: (1) chemical and structural characteristics; (2) pharmacokinetics and pharmacodynamics; (3) application in acute pain management; (4) adverse effects; and (5) drug safety. Overall, gabapentin has been reported to be a safe and efficacious drug for the treatment of postoperative pain. PMID:24829909

Postoperative calcitonin study in medullary thyroid carcinoma.  

PubMed

Calcitonin (CT) is a sensitive marker for medullary thyroid carcinoma. Normalization of early postoperative CT level is a favorable prognostic factor. The aim of this study was to establish the prognostic value of CT-level kinetics by preoperative tumor stage and postoperative elimination rate. Blood serum from 22 medullary thyroid carcinoma (MTC) patients without remote metastases was assayed. A commercial RIA DSL-1200 test was used to assay CT levels. Basal CT< or =42 pg/ml and stimulated CT< or =120 pg/ml were considered normal. The patients were divided into three groups according to the intensity of the postoperative CT level reduction in blood serum. Group 1 comprised patients who showed basal CT normalization within the first 2-3 days after surgery. Group 2 included those patients with slow (from 2 to 4 weeks) CT-level normalization. Group 3 included patients with CT levels that reduced within 14 days, but subsequently increased. Preoperative basal CT varies from 216 to 1654 pg/ml and depends on tumor-node-metastasis (TNM) stage. In seven patients, no basal CT decrease to normal values was observed; in five of these patients, disease recurrence was detected 2-6 months after surgery. In the group with slowly decreasing CT levels, no strong correlation between preoperative CT level and the postoperative time to normalization of basal and peak CT could be established; this may be due to the small number of patients. Our study showed that preoperative CT level depended on the disease stage. Postoperative CT elimination rate is independent of preoperative CT level. Postoperative increase in the basal or stimulated CT level is an unfavorable prognostic factor, implying disease recurrence. PMID:15163310

Pyropheophorbide und a as a catabolite of ethylene-induced chlorophyll und a degradation  

SciTech Connect

An enzyme extract prepared from ethylene-induced degreening Citrus fruits contains chlorophyll (Chl) degrading enzymes. The fate of Chl carbons during an enzymatic degradation was investigated using Chl {und a}-{sup 14}C. Accompanying the disappearance of labelled Chl {und a}, pheophorbide {und a} and pyropheophorbide {und a} appeared and accumulation of pyropheophorbide {und a} was observed. HydroxyChl {und a} was also detected, but this is thought to be an artifact during chromatography. Unlike ethylene-induced Citrus fruits (in vivo), further degradation of pyropheophorbide {und a} did not occur in vitro enzyme system. This suggests that there is a lack of enzyme(s) and/or cofactor(s) for further degradation. It is concluded that Chl {und a} degraded enzymatically by the following order: Chl {und a}, chlorophyllide {und a}, pheophorbide {und a} and pyropheophorbide {und a}.

Influences of Gender on Postoperative Morphine Consumption  

PubMed Central

Background: Gender related differences on morphine consumption during postoperative period following abdominal surgeries. Materials and Methods: Four hundred and fifty ASA I & II patients of either sex (male =231, female = 219), between the age group of 18-65 y undergoing elective intra abdominal surgeries under general anaesthesia were included for the study. Patients with preexisting pain either acute or chronic preoperatively were excluded from the study. Anaesthesia and analgesia protocol during surgery was standardized. Postoperatively, a loading dose was given to achieve the visual analogue scale (VAS) of ?30 and subjects were connected to patient control analgesia (PCA) pump containing 0.4 mg/ml of morphine configured to deliver a bolus dose (1 mg) with a 5 min lock-out period. The total analgesic requirements along with VAS (visual analog scale) score were analysed between males and females in the first 24 h postoperatively. All demographic data and between group comparisons were analysed with student t-test. Within group comparisons were done by using one-way-ANOVA test and Tukey’s Honestly significant Difference test. Results: During the first 24 h, males consumed significantly higher amount of morphine (34.35 ± 6.68 mg) when compared to females (26.78 ± 7.14 mg), p < 0.001. Conclusion: We conclude that men require more morphine in the postoperative period than women. PMID:25653963

Excess costs attributable to postoperative complications.  

PubMed

This article estimates excess costs associated with postoperative complications among inpatients treated in Veterans Health Administration (VA) hospitals. The authors conducted an observational study on 43,822 hospitalizations involving inpatient surgery in one of 104 VA hospitals during fiscal year 2007. Hospitalization-level cost regression analyses were performed to estimate the excess cost of each of 18 unique postoperative complications. The authors used generalized linear modeling techniques to account for the heavily skewed cost distribution. Costs were measured using an activity-based cost accounting system and complications were assessed based on medical chart review conducted by the VA 'National Surgical Quality Improvement Program. The authors found excess costs associated with postoperative complications ranging from $8,338 for "superficial surgical site infection" to $29,595 for "failure to wean within 24 hours in the presence of respiratory complications." The results obtained suggest that quality improvement efforts aimed at reducing postoperative complications can contribute significantly to lowering of hospital costs. PMID:21536599

The incidence of postoperative hydrocephalus and factors relating to it were analyzed in 257 patients undergoing cranial base surgery for tumor resection. A total of 21 (8%) patients developed postoperative hydrocephalus, and all required shunting, Forty-two (17%) patients developed cerebrospinal fluid (CSF) leak that required placement of external drainage systems (ventriculostomy or lumbar drain, or both); 10 (23%) of these 42 patients eventually needed shunt placement to stop the leak because of hydrocephalus. Prior craniotomy, prior radiation therapy, and postoperative CSF infection were also associated with an increased risk of developing hydrocephalus (48% versus 6%, 19% versus 8%, and 14% versus 7%, respectively). Prior radiation and postoperative CSF infection increased the risk of CSF leak in patients with hydrocephalus (30% versus 18% and 30% versus 9%, respectively). CSF leak and hydrocephalus commonly occurred in patients who underwent resection of a glomus tumor. In conclusion, 8% of patients who underwent cranial base surgery for tumors developed de novo hydrocephalus; half of them also had CSF leak in addition to hydrocephalus; and all required shunt placement for CSF diversion.

Development and implementation of a dedicated postoperative evaluation service to improve compliance of postoperative visits  

PubMed Central

Background and Aims: Postoperative patient evaluation is an integral component of perioperative care. An audit of our anesthesia department's records demonstrated a compliance rate of <50%. We postulated that the development of clinical anesthesia service dedicated to performing such evaluations would improve compliance significantly. Materials and Methods: This retrospective study examined postoperative follow-up completion rate at a large academic center. Data were collected from 58,000 anesthetics during three periods, between each of which an intervention was introduced. The first period examined completion rate when postoperative evaluations were left to the team performing the anesthetic. During the second period, this task was delegated to groups of anesthesiologists based on surgical subspecialty; these smaller groups utilized rotating residents. The third period examined completion rate after implementation of a postoperative evaluation service. All periods utilized the department's electronics database to identify operative patients. The number of adverse anesthesia events reported was also recorded. Results: A significant difference in the proportions of compliance with postoperative evaluations among all three periods was detected. Compliance was 47% during period one and improved to 66% during period two. During period three, which employed a postoperative evaluation service, compliance was 83%. The number of adverse events reported per month increased significantly following the first study period from 95 reported monthly events to 215 and 201 in the second and third periods, respectively. Conclusion: By creating a dedicated postoperative evaluation service using available technology, we improved postoperative evaluation completion rate from 47% to 83%, and demonstrated a significant increase in the number of adverse events reported. Based on this, we support the deployment of a dedicated service as a quality improvement initiative.

[Do anesthetic techniques influence postoperative outcomes? Part II].  

PubMed

The knowledge of the influence of anesthetic techniques in postoperative outcomes has opened a large field of research in recent years. In this second part, we review some of the major controversies arising from the literature on the impact of anesthetic techniques on postoperative outcomes in 6 areas: postoperative cognitive dysfunction, chronic postoperative pain, cancer recurrence, postoperative nausea/vomiting, surgical outcomes, and resources utilization. The development of protective and preventive anesthetic strategies against short and long-term postoperative complications will probably occupy an important role in our daily anesthetic practice. Dynamic postoperative pain control has been confirmed as one of the basic requirements of accelerated postoperative recovery programs ("fast-track surgery"), and it is also a preventive factor for development of chronic postoperative pain. The weight of anesthetic technique on postoperative immunosuppression is to be defined. The potential influence of anesthesia on cancer recurrence, is a highly controversial area of research. The classic pattern of perioperative fluid therapy may increase postoperative complications. On the other hand, the maintenance of normoglycemia and normothermia was associated with a decreased postoperative morbidity. The high volume of surgical procedures means that the adequacy of human, organizational and technological resources have a major impact on overall costs. PMID:23099035

A high level of suspicion is necessary to detect postoperative sepsis in good time. It may be difficult to differentiate sepsis from normal SIRS in the postoperative setting. Early signs and symptoms include delirium and respiratory compromise. These should trigger the search for a septic focus aggressively with special attention to the original site of surgery. Key recommendations include early goal-directed resuscitation of the septic patient, administration of broad-spectrum antibiotic therapy within 1 hour of diagnosis, and source control with attention to the balance of risks and benefits of the chosen method. In cases of severe abdominal sepsis the concept of relaparotomy on-demand has become most popular. PMID:20549587

Critic appraisal. Postoperative sensitivity with indirect restorations.  

PubMed

Postoperative sensitivity is characterized by short and sharp pain, and often experienced after cementation of indirect restorations. Factors associated with the occurrence of post-cementation sensitivity include type of cement, removal of smear layer by acid-etching, aggressive tooth preparation, inadequate provisional restorations, and patient's age. Its prevention is based on either interfering with mechanoreceptor activity or occluding the dentinal tubules. Regarding the latter, application of dentin desensitizers may be effective for blocking the tubules and significantly reducing dentin permeability and consequently postoperative sensitivity. This Critical Appraisal will present available clinical data where traditional materials such as zinc phosphate and glass ionomer cements (GIC) as well as self-adhesive resin-based cements were used.

Perspectives on the importance of postoperative ileus.  

PubMed

Post-operative ileus (POI) is a common condition after surgery. Failure to restore adequate bowel function after surgery generates a series of complications and it is associated to patients frustration and discomfort, worsening their perioperative experience. Even mild POI can be source of anxiety and could be perceived as a drop out from the "straight-forward" pathway. Enhanced recovery programmes have emphasized the importance of early commencement of oral diet, avoiding the ancient dogmata of prolonged gastric decompression and fasting. These protocols with early oral feeding and mobilization have led to improved perioperative management and have decreased hospital length of stay, ameliorating patient's postoperative experience as well. Nonetheless, the incidence of POI is still high especially after major open abdominal surgery. In order to decrease the incidence of POI, minimally-invasive surgical approaches and minimization of surgical manipulation have been suggested. From a pharmacological perspective, a meta-analysis of pro-kinetics showed beneficial results with alvimopan, although its use has been limited by the augmented risk of myocardial infarction and the high costs. A more simple approach based on the postoperative use of chewing-gum has provided some benefits in restoring bowel function. From an anaesthesiological perspective, epidural anaesthesia/analgesia does not only reduce the postoperative consumption of systemic opioids but directly improve gastrointestinal function and should be considered where possible, at least for open surgical procedures. POI represents a common and debilitating complication that should be challenged with multi-disciplinary approach. Prospective research is warranted on this field and should focus also on patient s reported outcomes. PMID:25753356

Postoperative doppler evaluation of liver transplants  

PubMed Central

Doppler ultrasound plays an important role in the postoperative management of hepatic transplantation, by enabling early detection and treatment of various vascular complications. This article describes the normal Doppler findings following liver transplantation and reviews the imaging appearances of various vascular complications associated with it. The article also discusses transient waveform abnormalities, often seen on a post-transplant Doppler examination, and the importance of differentiating them from findings suggestive of ominous vascular complications.

Postoperative complications with protruding monofilament nylon sutures.  

PubMed

Cut ends of 10-0 monofilament nylon sutures protruded and caused various combinations of severe pain, conjunctival inflammation, tarsal conjunctival ulcerations, eyelid edema, and corneal epithelial erosions in six patients postoperatively. These changes occurred one to three weeks after keratoplasty and one to three months after cataract surgery. In all six patients the signs and symptoms cleared after we trimmed or removed the offending sutures. PMID:326051

Denken in Wertschöpfung und Verschwendung  

NASA Astrophysics Data System (ADS)

Eine Antwort auf die Frage welche Arbeitsschritte, Aktivitäten und Prozesse als wertschöpfend betrachtet werden können, erhält man durch die Überlegung, ob der Kunde bereit ist dafür zu zahlen. Kunden sind sicher bereit dafür zu zahlen, dass z.B. die Räder an ihrem neuen PKW sicher montiert sind. Die im Unternehmen notwendigen logistischen Prozesse, die die Räder zu ihrem Montageort transportieren, sind aus Sicht des Kunden dagegen mit keinem Wert verbunden. Insofern ist er nicht bereit dafür zu zahlen und sämtliche internen logistischen Aktivitäten sind entsprechend nicht wertschöpfend. Verschwendung bzw. nicht wertschöpfende Arbeit umfasst alle Aktivitäten, Tätigkeiten und Prozesse, die Zeit, Ressourcen und/oder Raum kosten, aber nicht zur Erfüllung der Kundenanforderungen beitragen. Verschwendung ist damit der Teil der Arbeit, für den der Kunde nicht zahlt, z.B. den internen Transport von Bauteilen zum Montageort.

Adjuvant postoperative radiation therapy for colonic carcinoma.  

PubMed Central

One hundred thirty-three patients with Stage B2, B3, and C colonic carcinoma had resection for curative intent followed by adjuvant postoperative radiotherapy to the tumor bed. The 5-year actuarial local control and disease-free survival rates for these 133 patients were 82% and 61%, respectively. Stage for stage, the development of local regional failure was reduced for patients receiving postoperative radiotherapy compared with a historic control series. Local recurrence occurred in 8%, 21%, and 31% of patients with Stage B3, C2, and C3 tumors who had radiation therapy, respectively, whereas the local failure rates were 31%, 36%, and 53% in patients treated with surgery alone. There was a 13% and 12% improvement in the 5-year disease-free survival rate in the patients with Stage B3 and C3 lesions who had radiotherapy compared with the historic controls. For patients with Stage C disease, local control and disease-free survival rates decreased progressively with increasing nodal involvement; however, local control and disease-free survival rates were higher in the patients who had radiotherapy than in those who had surgery alone. Failure patterns in the patients who had radiotherapy did not show any notable changes compared with those for patients who had surgery alone. Postoperative radiation therapy for Stage B3, C2, and C3 colonic carcinoma is a promising treatment approach that deserves further investigation. PMID:3689006

[Postoperative complications and management of filtration surgery].  

PubMed

Of the filtering procedures employed, trabeculectomy is the one most frequently used for surgical therapy in primary open angle glaucoma patients. Intra- and postoperative complications must be detected promptly and treated adequately. Many complications arise within the first weeks, such as bleb scaring, decreased flow beneath the scleral flap, extensive filtration with choroidal detachment and anterior chamber narrowing. Fibrin reaction, corneal dellen, iris prolapse, conjunctival leakage and ciliary body detachment are seen more rarely. With prophylactic pre- and perioperative application of antibiotics, wound infections are rare and the risk of endophthalmitis following trabeculectomy remains small. Careful surgical planning requires special consideration of the conjunctiva and provides the basis for long-term success as long as intensive follow-up treatment is ensured. The success of trabeculectomy depends on the preoperative, intraoperative as well as postoperative condition and in particular on bleb development. Early detection of postoperative complications, especially in terms of early scaring in the bleb area, enables implementation of adequate therapeutic measures, such as needling procedures and early bleb revision. Close patient monitoring substantially increases long-term success rates. PMID:19908048

[Preoperative and postoperative management of adrenal masses].  

PubMed

The surgical approach of adrenal masses requires a careful preoperative and postoperative management. In order to avoid iatrogenic hypocortisolism, Cushing patients have to be treated, before adrenal surgery and then every eight hours, with hydrocortisone 100 mg iv. The therapy should be gradually reduced to 10-20 mg/die by mouth for six-twelve months. In primary hyperaldosteronism the target of medical treatment is to control blood pressure and serum potassium values as well as to normalize the circulating aldosterone levels or to obtain mineralocorticoid receptor blockade. Epleronone and spironolactone are the most common used drugs. Spironolactone has long been the drug of choice while epleronone represents a newer more expensive alternative with fewer side effects. Postoperative management generally does not require steroid replacement therapy. The management of pheochromocytoma requires a careful medical preparation for surgery: in fact, the surgical removal of a pheochromocytoma is a high-risk procedure and an experienced surgeon/anesthesiologist team is required. The preoperative medical therapy is aimed at controlling hypertension (including preventing a hypertensive crisis during surgery) and at avoiding cardiac arrhythmia. The most common used drugs are alpha-adrenergic blockade: phenoxybenzamine is an irreversible, long-acting, nonspecific alpha-adrenergic blocking agent. Doxazosine is a selective alpha1-adrenergic blocking agent with a more favorable side-effect profile, being less related to postoperative hypotension. Postsurgical management is aimed at expanding plasma volume: a copious hydration is required while the use of dopamine in hemodynamin support is not effective because of the preoperative use of alpha-blocking agents.

Creation of postoperative adhesions is a part of every abdominal operation. The authors analyse 320 patients operated for ileus in last 7 years. 118 patients were operated for adhesive ileus. Most common reoperations for ileus are after radical gynecological operations and inflammatory intraabdominal diseases. The creation of adhesiones depends on preoperative mechanical or chemical damage of tissues and peritoneum, bacterial infection and irradiation. The major complication of intraabdominal adhesions are disturbances of bowel function what leads to subileus or ileus. Authors present therapeutical possibilities and prefer laparoscopic operations.

Histologic features predicting postoperative Crohn's disease recurrence.  

PubMed

Recurrence of Crohn's disease (CD) after ileal or colonic resection is common. Many studies have tried to identify predictors of postoperative recurrence (POR) in CD. A wide range of histologic features have been identified, but for most of them, the literature provided conflicting data. In last years, several studies have suggested that histologic findings including inflammatory changes within the enteric nervous system of the resection margin may be associated with CD recurrence. Herein, after briefly summarizing pathophysiology of POR, we review all histological features that have been studied so far: granulomas, histologic appearance at the margin of resection, plexitis, lymphatic vessel density in proximal margin of resection, and morphological analysis of Paneth cells. Granulomas and chronic inflammation at the margin of resection do not seem to predict POR in CD. Active disease at the margin of resection, plexitis, lymphatic vessels density, morphological analysis of Paneth cells may predict POR. Most of these histological features await replication in independent studies. Available evidence indicates that histological findings may be taken into account when developing strategies aimed at preventing postoperative CD recurrence. PMID:25437814

Postoperative Alterations in Taste and Smell  

PubMed Central

Context: Alterations in taste and smell, including but not limited to anosmia, ageusia, hypogeusia, and dysgeusia, have been described in association with various medications, including anesthetic agents. Frequently, these symptoms occur 1-2 weeks after medication administration and last several months. While such a phenomenon is a rare occurrence, it nonetheless can significantly impact patients’ satisfaction and quality of life. Evidence Acquisition: The methodology consisted of a thorough literature search using the MEDLINE and Cochrane databases utilizing keywords such as anosmia, ageusia, olfactory disorders, postoperative, and anesthesia. Results: Our results yielded several previously published case report, and were not limited to a specific type of anesthesia. Based on available literature, we review the physiology of taste and smell as well as the medications associated with loss of these senses. We describe perioperative agents that could lead to postoperative complications associated with anosmia and and ageusia. Conclusions: Based on available literature recommendations for anesthesiologists caring for patients at risk for this occurrence are presented in this review. The symptoms are usually temporary as in the majority of the patients the sensory receptor cells are able to regenerate themselves after injury. Anesthesia providers need to aware of this phenomenon to be able to reassure patients and possibly avoid anesthetic techniques associated with anosmia and ageusia. PMID:25599025

[Postoperative pain in children: a gender approach].  

PubMed

The objective of this study was to verify and describe, from a gender focus, the associations between gender and specific postoperative pain variables in pediatrics. This is a cross-sectional study of 77 children between 6 and 13 years of age (M=9 years; sd=2.2 years), ASA I and II, 77.9% from low-income classes, 68.8% boys and 32.8% girls. Data were collected on the first postoperative (1st PO) day through semi-structured interviews and four measurement scales. The main baseline diseases were adenotonsillitis and fractures. Prevalence of pain on the 1st PO was 91.7% for girls and 75.5% for boys (p>0.05). No association was found between pain intensity and gender. The most used pain descriptors were it cuts and it squeezes. The preferred scale was the EFMC (with faces from a Brazilian cartoon: Monica's Gang). Pediatric pain management is still inadequate and gender may influence the pain response. PMID:21876881

Management of recurrent postoperative fungal endophthalmitis  

PubMed Central

Aim: To report the management of recurrent postoperative fungal endophthalmitis (POFE) after failed pars plana vitrectomy (PPV) and antifungal therapy. Settings and Design: Tertiary Care Referral Centre in North India. Retrospective, single institution, interventional case-series. Materials and Methods: Six patients with microbiologically proven recurrent post-operative fungal endophthalmitis refractory to conventional management were included. The final recurrence was managed with intraocular lens (IOL) explantation and re-PPV. Main outcome measures included preserved globe anatomy, visual acuity and retinal status. ‘Anatomical success’ was defined as preserved anatomy of the globe, and absence of signs of inflammation. ‘Functional success’ was defined as an attached retina and a best corrected visual acuity of better than 20/400. Results: Of the six cases of POFE, five were culture positive [Aspergillus flavus (1), Aspergillus fumigatus (2), Candida albicans (1) and Candida glabrata (1)] and one was smear positive for yeast. All recurred (mean recurrences, 4) despite a mean of 2.17 PPVs and intravitreal amphotericin B. No recurrences were observed after IOL explantation with re – PPV (median follow-up, 37 months). Pre-study defined criteria for successful ‘anatomical’ and ‘functional’ outcomes were achieved in 83.3% and 50% respectively. Conclusion: This report highlights the effective role of combined IOL explantation with PPV in managing recurrent POFE. PMID:24618484

Postoperative Radiation Therapy for Parotid Mucoepidermoid Carcinoma  

PubMed Central

Salivary gland cancers are rare and represent approximately 5% of all head and neck cancers and only 0.3% of all malignancies. The majority (75%) of salivary gland tumors occur in the parotid gland, and while benign lesions are more common, mucoepidermoid carcinoma (MEC) makes up 40–50% of malignant parotid gland tumors. No randomized controlled trials exist regarding the role of adjuvant radiation for patients who undergo surgical resection of low-grade MECs. Herein, we report two cases of successful postoperative radiation therapy in low-grade, pT2N0 MEC of the parotid gland. The role of adjuvant radiation therapy for patients with MEC of the parotid gland is based on data from institution reviews and lacks data from randomized controlled trials. Per our review of the literature, the pathological findings of positive surgical margins and/or perineural invasion in two patients with low-grade MEC of the parotid gland warranted adjuvant radiation for improved local control after partial parotidectomy. Both patients tolerated postoperative radiation therapy with only mild side effects and, at last follow-up, five years after completion of therapy, had no clinical or radiographic evidence of either local recurrence or distant metastasis.

Background: Considering the important role of pituitary gland in regulating various endocrine axes and its unique anatomical location, various postoperative complications can be anticipated resulting from surgery on pituitary tumors. We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay) in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe. PMID:25191182

Preoperative, intraoperative, and postoperative measures to further reduce spinal infections  

PubMed Central

Background: The rate of postoperative spinal infections varies from 0.4% to 3.5%. Although the introduction of additional preoperative, intraoperative, and postoperative methods of prophylaxis should further reduce spinal infection rates, these measures will not succeed unless surgeons are well informed of their availability, utility, and efficacy. This study provides a review of several preoperative, intraoperative, and postoperative methods of prophylaxis that could minimize the risk of postoperative spinal infections. Various preoperative, intraoperative, and postoperative measures could further reduce the risk of spinal infections. Preoperative prophylaxis against methicillin-resistant Staphylococcus aureus could utilize (1) nasal cultures and Bactroban ointment (mupirocin), and (2) multiple prophylactic preoperative applications of chlorhexidine gluconate (CHG) 4% to the skin. Intraoperative prophylactic measures should not only include the routine use of an antibiotic administered within 60 min of the incision, but should also include copious intraoperative irrigation [normal saline (NS) and/or NS with an antibiotic]. Intraoperatively, instrumentation coated with antibiotics, and/or the topical application of antibiotics may further reduce the infection risk. Whether postoperative infections are reduced with the continued use of antibiotic prophylaxis remains controversial. Other postoperative measures may include utilization of a silver (AgNO3)-impregnated dressing (Silverlon dressing) and the continued use of bed baths with CHG 4%. The introduction of multiple preoperative, intraoperative, and postoperative modalities in addition to standardized prophylaxis may further contribute to reducing postoperative spinal infections.

Nefopam and Ketamine Comparably Enhance Postoperative Analgesia  

PubMed Central

Summary Opioids alone sometimes provide insufficient postoperative analgesia. Co-administration of drugs may reduce opioid use and to improve opioid efficacy. We therefore tested the hypothesis that administration of ketamine or nefopam, to postoperative patients with pain only partly alleviated by morphine, limits the amount of subsequent opioid necessary to produce adequate analgesia. Patients (n=77) recovering from major surgery were given up to 9 mg intravenous morphine. Those still suffering from pain were randomly assigned to blinded administration of: 1) isotonic saline (Control, n=21); 2) ketamine 10 mg (Ketamine, n=22); or, 3) nefopam 20 mg (Nefopam, n=22). Three-mg morphine boluses were subsequently given at 5-minute intervals until adequate analgesia was obtained, or 60 minutes elapsed after the beginning of the study drug administration, or ventilation became insufficient (respiratory rate < 10 breath/minute or saturation by pulse oxymetery < 95%). Supplemental morphine (i.e., after test drug administration) requirements were significantly greater in the Control group [17 ± 10 (SD) mg] than in the Nefopam (10 ± 5 mg, P < 0.005) or Ketamine (9 ± 5 mg, P < 0.001) groups. Morphine titration was successful in all Ketamine and Nefopam patients, but failed in four Control patients (two from respiratory toxicity and two from persistent pain). Tachycardia and profuse sweating were more frequent in patients given nefopam and sedation was greater with ketamine; however, the incidence of other potential complications did not differ between groups. Implications We conclude that ketamine 10 mg and nefopam 20 mg comparably potentiate opioid analgesia, each reducing opioid need by approximately 40%. Ketamine administration was associated with sedation whereas nefopam produced tachycardia and sweating. However, none of the side effects was serious. Either drug can thus be used to potentiate opioid analgesia. PMID:15616073

Lineare und verzweigte Blockcopolymere aus Polypeptiden und synthetischen Polymeren  

NASA Astrophysics Data System (ADS)

Die vorliegende Arbeit beschäftigt sich mit der Synthese und den Eigenschaften von linearen und verzweigten amphiphilen Polypeptid-Blockcopolymeren. Die Frage nach dem Einfluss der Topologie und Konformation der Blockcopolymere auf die supramolekularen und kolloidalen Eigenschaften bildete einen wichtigen Aspekt bei den Untersuchungen. Die Blockcopolymere wurden nach einem mehrstufigen Reaktionsschema durch Kombination von anionischer und ringöffnender Polymerisation von Aminosäuren-N-Carboxyanhydriden (NCA) synthetisiert. Die Untersuchung der Polypeptid-Blockcopolymere hinsichtlich ihres Aggregationsverhaltens in fester Phase sowie in verdünnter wässriger Lösung erfolgte mittels Streumethoden (SAXS, WAXS, DLS) sowie abbildender Methoden (TEM). Durch Einsatz der Blockcopolymere als polymere Stabilisatoren in der Emulsionspolymerisation wurden Oberflächen funktionalisierte Latizes erhalten. Als Beispiel für eine pharmazeutische Anwendung wurden bioverträgliche Polypeptid-Blockcopolymere als Wirkstoff-Trägersysteme in der Krebstherapie eingesetzt. This work describes the synthesis and characterization of linear and branched polypeptide block copolymers having amphiphilic character. The studies focused on the impact of the block copolymers' conformation and architecture on the supramolecular and colloidal properties. The polypeptide block copolymers were prepared in a multi-step process involving the anionic synthesis of (poly)amino-functional polymers (polystyrene and polybutadiene) which where used as macroinitiators for the ring-opening polymerization of N-carboxyanhydrides (NCA) of protected a-aminoacids. Supramolecular structures of the block copolymers in the solid state as well as in diluted aqueous solution were investigated using scattering (SAXS, WAXS, DLS) and microscopic (TEM) methods. Both linear and branched polypeptide block copolymers were used as polymeric stabilizers in the emulsion polymerization of styrene to yield polypeptide-decorated latexes. Biocompatible block copolymers were used as drug-delivery systems in lymphatic cancer therapy.

Currently, there are no studies that specifically examine CO2 levels in the context of complications after radical cystectomy; therefore, we also present our own institutional data which demonstrate that a drop in postoperative CO2 levels is highly predictive of complications, the most common of which is failure to thrive. These data indicate that significant changes in CO2 levels prior to discharge after a radical cystectomy may be a harbinger of forthcoming complications. PMID:25773345

The postoperative morbidity index: a quantitative weighing of postoperative complications applied to urological procedures  

PubMed Central

Background The reporting of post-operative complications in the urological field is lacking of a uniform quantitative measure to assess severity, which is essential in the analysis of surgical outcomes. The purpose of this study was to evaluate the feasibility of estimating quantitative severity weighing of post-operative complications after common urologic procedures. Methods Using a large healthcare system’s quality database, complications were identified in eleven common urologic procedures (e.g., insertion or replacement of inflatable penile prosthesis, nephroureterectomy, partial nephrectomy, percutaneous nephrostomy tube placement, radical cystectomy, radical prostatectomy, renal/ureteral/bladder extracorporeal shockwave lithotripsy (ESWL), transurethral destruction of bladder lesion, transurethral prostatectomy, transurethral removal of ureteral obstruction, and ureteral catheterization) from January 1, 2011 to December 31, 2011. Complications were classified by the Expanded Accordion Severity Grading System, which was then quantified by validated severity weighting scores. The Postoperative Morbidity Index (PMI) for each procedure was calculated where an index of 0 would indicate no complication in any patient and an index of 1 would indicate that all patients died. Results This study included 654 procedures of which 148 (22%) had one or more complications. As would be expected, a more complex procedure like radical cystectomy possessed a higher PMI (0.267), while a simpler procedure like percutaneous nephrostomy tube placement possessed a lower PMI (0.011). The PMI of the additional nine procedures fell within the range of these PMIs. These PMIs could be used to compare surgeons, hospitals or procedures. Conclusions Quantitative severity weighing of post-operative complications for urologic procedures is feasible and may provide exceptionally informative data related to outcomes. PMID:24383457

Preventive analgesia for postoperative pain control: a broader concept  

PubMed Central

Pain from surgical procedures occurs as a consequence of tissue trauma and may result in physical, cognitive, and emotional discomfort. Almost a century ago, researchers first described a possible relationship between intraoperative tissue damage and an intensification of acute pain and long-term postoperative pain, now referred to as central sensitization. Nociceptor activation is mediated by chemicals that are released in response to cellular or tissue damage. Pre-emptive analgesia is an important concept in understanding treatment strategies for postoperative analgesia. Pre-emptive analgesia focuses on postoperative pain control and the prevention of central sensitization and chronic neuropathic pain by providing analgesia administered preoperatively but not after surgical incision. Additional research in pre-emptive analgesia is warranted to better determine good outcome measurements and a better appreciation with regard to treatment optimization. Preventive analgesia reduces postoperative pain and consumption of analgesics, and this appears to be the most effective means of decreasing postoperative pain. Preventive analgesia, which includes multimodal preoperative and postoperative analgesic therapies, results in decreased postoperative pain and less postoperative consumption of analgesics.

Risk factors of postoperative myocardial infarction after colorectal surgeries.  

PubMed

There are limited data regarding the specific risk factors of postoperative myocardial infarction (MI) in patients undergoing colorectal resectional surgery. We sought to identify risk factors of acute MI after colorectal resection operations. The National Inpatient Sample database was used to identify patients who had postoperative MI after colorectal resection operations between 2002 and 2010. Statistical analysis was performed to identify factors predictive of postoperative MI. We sampled a total of 2,513,124 patients undergoing colorectal resection, of whom 38,317 (1.5%) sustained a postoperative MI. Patients with postoperative MI had associated 28.5 per cent in-hospital mortality. Risk factors identified include (P < 0.01): history of congestive heart failure (odds ratio [OR], 8.18), chronic renal failure (OR, 3.86), age 70 years or older (OR, 3.68), peripheral vascular disorders (OR, 2.93), fluid and electrolyte disorders (OR, 2.69), emergency admission (OR, 2.56), preoperative weight loss (OR, 2.49), cardiac valvular disease (OR, 2.46), chronic lung disease (OR, 1.75), deficiency anemia (OR, 1.22), colorectal cancer (OR, 1.77), and hypertension (OR, 1.14). Postoperative MI occurs in less than 2 per cent of colorectal resections. However, patients sustaining postoperative MI are over six times more likely to die. Congestive heart failure and chronic renal failure are the strongest predictors of postoperative MI. PMID:25831181

Diagnosis, Prevention and Management of Postoperative Pulmonary Edema  

PubMed Central

Postoperative pulmonary edema is a well-known postoperative complication caused as a result of numerous etiological factors which can be easily detected by a careful surveillance during postoperative period. However, there are no preoperative and intraoperative criteria which can successfully establish the possibilities for development of postoperative pulmonary edema. The aims were to review the possible etiologic and diagnostic challenges in timely detection of postoperative pulmonary edema and to discuss the various management strategies for prevention of this postoperative complication so as to decrease morbidity and mortality. The various search engines for preparation of this manuscript were used which included Entrez (including Pubmed and Pubmed Central), NIH.gov, Medknow.com, Medscape.com, WebMD.com, Scopus, Science Direct, MedHelp.org, yahoo.com and google.com. Manual search was carried out and various text books and journals of anesthesia and critical care medicine were also searched. From the information gathered, it was observed that postoperative cardiogenic pulmonary edema in patients with serious cardiovascular diseases is most common followed by noncardiogenic pulmonary edema which can be due to fluid overload in the postoperative period or it can be negative pressure pulmonary edema (NPPE). NPPE is an important clinical entity in immediate post-extubation period and occurs due to acute upper airway obstruction and creation of acute negative intrathoracic pressure. NPPE carries a good prognosis if promptly diagnosed and appropriately treated with or without mechanical ventilation. PMID:23439791

Bile reflux in postoperative alkaline reflux gastritis.  

PubMed Central

This study evaluates enterogastric reflux (EGR) levels in patients with and without symptoms of postoperative alkaline reflux gastritis (PARG) after gastric surgery. The bile acids (BA) present in the gastric juice were quantified by thin-layer chromatography and spectrofluorometry. The mean BA concentration for controls was 2.25 mumol reflux/hour, for 15 asymptomatic patients 47.94 and for 15 patients with symptoms of PARG 125.79. After biliary diversion by a Roux-en-Y anastomosis in the latter, their BA in 13 of these patients after surgery, and relapsed in only one during a 4-year follow-up. The remaining two patients had the lowest preoperative BA levels in this group. These results indicate that EGR is increased after gastric surgery more markedly indicated that EGR is increased after gastric surgery more markedly in patients with symptoms of PARG, and that patients who have high levels of EGR (more than 80 mumol BA reflux/hour) clearly benefit from biliary diversion.

[Factors responsible for post-operative infection].  

PubMed

Post-operative infection is often due to a combination of several factors. A decrease in immune defence processes represents the first factor. This is seen in situations such as malnutrition (undernourishment or obesity), alcoholism, diabetes, neoplasms, infections and old age. It may also be induced by therapy such as immunodepressants, antimitotic chemotherapy, corticosteroids and radiotherapy. Finally, certain antibiotics have been accused of reducing immune defences. The second factor responsible for infection is bacterial flora. Errors such as broad spectrum antibiotic therapy prescribed in the presence of unexplored fever, or changed repeatedly, are responsible for imbalance in the bacterial flora and the acquisition of resistance to antibiotics. These errors firstly increased the prevalence of infections and, secondly their severity and the difficulty of their treatment. The last factor responsible for infection is rupture of the natural barriers formed by the skin and mucosae. This is related on the one hand to surgery itself and, secondly, to the intensive care techniques surrounding the surgical act: venous catheterization above all, but also bladder catheterization, tracheal intubation, etc. PMID:44967

Acute postoperative complications of hypospadias repair  

PubMed Central

Purpose Complications in hypospadias surgery are higher than other reconstructive procedures. The incidence of complications can be reduced if proper preventive measures are taken. The review aims to highlight incidences, causes, and preventive measures of acute complications of hypospadias repair. Materials and Methods Literature reports were reviewed in Pubmed by giving the key word acute complications of hypospadias repair, wound infection, wound dehiscence, flap necrosis, edema, penile torsion, urethral fistula, bleeding and hematoma and urethral stents problems. Summaries of all articles were reviewed with full text of relevant article and results were analyzed. Results Besides mentioning the complications of hypospadias repair in individual articles on the subject, we did not come across any separate article on this subject in the published English literature. Fistula is the commonest complication followed by edema and penile torsion. Conclusions Most acute complications can be prevented with adherence to principles of plastic and microsurgery, meticulous preoperative planning, and judicious postoperative care. Deviation from these principles may lead to disaster and even failure of the repair. The aim in hypospadias surgery should be following these principles and bring down the complication rates < 5% in distal hypospadias and < 10% in proximal hypospadias. PMID:19468404

Takotsubo cardiomyopathy presenting as postoperative atrial fibrillation.  

PubMed

Takotsubo cardiomyopathy (TC) is a condition which was first acknowledged in Japan and is characterized by a reversible systolic dysfunction of the apical or mid segments of the left ventricle. Typically affecting women in the post-menopausal population, it is triggered by intense emotional, physical or medical stress. Also known as apical ballooning syndrome or stress cardiomyopathy, TC derives its name from the left ventricular angiographic appearance of a 'Takotsubo', literally translated as an 'octopus fishing trap' in Japanese. Patients often describe chest pain, have ischemic electrocardiogram (ECG) changes and positive cardiac enzymes mimicking an acute coronary syndrome. Obstructive coronary artery disease is excluded with prompt cardiac catheterization. We present the case of a 78-year-old lady, post gynecological surgery, presenting with palpitations and ECG confirming fast atrial fibrillation. Despite spontaneous cardioversion, she went on to develop ECG changes and cardiac enzyme elevations suggestive of an acute myocardial infarction. Cardiac catheterization was performed and confirmed the diagnosis of TC. It highlights an atypical presentation of TC, which can present initially as an arrhythmia in the postoperative phase as a consequence of the supraphysiological effects of elevated circulating plasma catecholamines. It reiterates the importance of prompt diagnosis and treatment to prevent cardiac decompensation in a condition poorly understood. PMID:20739768

Undivided attention improves postoperative anesthesia handover recall  

PubMed Central

Background For years, undivided attention during the presurgical “timeout” has been utilized as a precaution to ensure patient safety. The information relayed during the timeout is presented in a confirmatory nature rather than a delegation of new information. However, it is a standard of practice in which all members of the operating theater provide their full and undivided attention. Standards of patient care should be contiguous throughout the preoperative, perioperative, and postoperative stages of surgery. In this manner, it is expected that the same undivided attention afforded during the timeout should be maintained when transferring the patient to the postanesthesia care unit. Methods In this study, information was collected regarding handover of information during the transfer status postsurgical procedures. Data were collected via observing interactions between the anesthesiologist and the nurse during verbal patient transfers. Results This study demonstrated that the presence of undivided attention during the handover of a surgical patient in the postanesthesia care unit has a direct correlation with improved recall of the information discussed during handover. Conclusion Focus is on the quantity of information that can be recalled by the transferring nurse, and whether or not undivided attention affects the outcome. Analysis focuses on suggestions to better improve patient safety and recovery when being transferred in an anesthetic setting. The practice of patient handover should be standardized to better improve the safety and quality of medical care. PMID:25031549

Diagnosis, prevention and treatment of postoperative Crohn's disease recurrence.  

PubMed

Ileocolonoscopy remains the gold standard in diagnosing postoperative recurrence. After excluding stricture, wireless capsule endoscopy seemed accurate in small series, but no validated score is available. Ultrasonography is a non-invasive diagnostic method reducing radiation exposure and emerging as an alternative tool for identifying post-operative recurrence. Computed tomography enteroclysis yields objective morphologic criteria that help differentiate between recurrent disease and fibrostenosis at the anastomotic site, but ionising radiation exposure limits its use. Magnetic resonance imaging may be as powerful as ileocolonoscopy in diagnosing postoperative recurrence and in predicting the clinical outcome using specific MR-scores. Biomarkers such as faecal calprotectin and faecal lactoferrin showed promising results, but their specificity in the postoperative period will require further investigation. Numerous medications have been tested to prevent and/or to treat postoperative recurrence. Efficacy of mesalamine is very low and comparable to placebo in most series. Thiopurines have modest efficacy in the postoperative setting and are associated with a high rate of adverse events leading to drug withdrawal. Antibiotics such as metronidazole or ornidazole may be effective, but toxicity and drug resistance prevent their long-term use. Anti-Tumour Necrosis Factor therapy is the most potent drug class to prevent and to treat postoperative recurrence in Crohn's disease. PMID:22265329

Postoperative necrotizing scleritis should be considered in cases of persistent localized postoperative inflammation following all forms of surgical trauma. We present the history, clinical findings, and follow-up data of four patients with postoperative necrotizing scleritis. The clinical records of four patients who developed scleritis following ocular surgery were retrospectively reviewed. The first step in managing necrotizing scleritis is to rule out infectious etiology. Surgically induced necrotizing scleritis is an immune-mediated condition that can coexist with concomitant infectious condition, i.e. endophthalmitis, but response to immunosuppression leads to resolution of the disease and verifies the diagnosis.

Postoperative therapy options for hepatocellular carcinoma.  

PubMed

Hepatocellular carcinoma (HCC) is associated with poor prognosis and often recurs even after curative hepatic resection (HR) or radiofrequency ablation (RFA). In fact, recurrence is the most frequent cause of postoperative death in patients with HCC; it can arise through intrahepatic metastasis by the primary tumor or through the emergence of de novo tumors. Even though studies have examined numerous adjuvant therapies and chemotherapies for their ability to prevent recurrence, no consensus recommendations exist about their clinical application. To gain a comprehensive picture of clinical options, we identified 39 randomized controlled trials, involving 4113 participants, which explore the efficacy of adjuvant or chemotherapies to prevent HCC recurrence after potentially curative HR or RFA. The available evidence suggests a significant improvement in recurrence-free survival and overall survival when transarterial chemoembolization is used for patients who are at high risk for recurrence, lamivudine for patients with hepatitis B virus (HBV)-related HCC (>500 copies of HBV DNA/ml), and interferon-? for patients with hepatitis C virus (HCV)-infected HCC. In contrast, available evidence does not definitively establish clinical benefits of interferon-? for patients with HCV-related HCC, interferon-? for patients with HBV-related HCC, or any of the following therapies for patients with HCC: iodine-125 brachytherapy, autologous tumor vaccination, adoptive immunotherapy, or therapy involving acyclic retinoid, vitamin K2 analog, iodine-131-labeled lipiodol, sorafenib, heparanase inhibitor PI-88, or capecitabine. Though the findings of our review should be interpreted with caution because of clinical heterogeneity and small sample size in the included trials, they highlight gaps in the evidence base, and therefore, may guide future research.

Bilateral postoperative maxillary cysts after orthognathic surgery: A case report  

PubMed Central

Postoperative maxillary cysts are locally aggressive lesions, usually developing as delayed complications many years after radical antral surgery. This report describes a case of bilateral postoperative maxillary cysts following orthognathic surgery performed approximately 21 years previously. The patient complained of stinging pain on her right cheek. Radiographic examination revealed low-attenuation lesions on both maxillary sinuses with discontinuously corticated margins without distinct expansion or bone destruction. The cysts were enucleated with the removal of metal plates and screws for pain relief. Histopathological examination confirmed the diagnosis of postoperative maxillary cysts lined by ciliated, pseudostratified columnar cells. The patient has remained asymptomatic thus far, and there was no evidence of local recurrence at 21 months of postoperative follow-up. PMID:25473641

Aqueous acupuncture for postoperative pain--a matched controlled trial.  

PubMed

The analgesic effects of acupuncture are well-documented. Aqueous acupuncture, or point injection, is a conveniently modified modern acupuncture method. This matched controlled trial was carried out to evaluate the effects of aqueous acupuncture in postoperative pain control. A total of 12 patients were selected as age-, sex- and operative-style-matched controls. In treating group, 2 to 5 ml of 20% glucose solution was injected into Ho-Ku (LI 4) and Yang-Ling-Chuan (GB 34) when patients had regained conciousness from operation anesthesia. The pain intensity were recorded as score system included verbal, sleep disturbance and use of narcotics. In comparisons with the control group, the intensity of postoperative pain, and the amounts and frequency of narcotics used were significantly lower in the study group, especially for the first 12 postoperative hours. Aqueous acupuncture is a convenient and effective procedure in postoperative pain control. PMID:1779440

[Ketoprofen (ketonal): a drug for preventing and treating postoperative pain].  

PubMed

A prophylactic approach to the management of postoperative pain is described: ketoprofen, a nonsteroid antiinflammatory drug, was used, which possesses numerous advantages and a variety of dosage forms. To cancer patients subjected to extensive radical operations on the pelvic organs, head, and neck, ketonal (ketoprofen) was injected intramuscularly or rectally in a dose of 100 mg 1 h before surgery and in a daily dose of 300 mg during the postoperative period. Adequate postoperative monoanalgesia with ketonal was attained in 47% patients. In the rest patients ketonal was combined with medium-potent opioid tramadol. A more potent opioid buprenorfin (sangesik) in the minimal daily dose of 0.3 mg was required in only 2 cases. Nonsteroid antiinflammatory drug ketoprofen (ketonal) in therapeutic doses administered preventively before surgery intramuscularly or rectally notably decreased the acuity of the postoperative pain syndrome.

Risk of postoperative recurrence and postoperative management of Crohn’s disease  

PubMed Central

Crohn’s disease (CD) is a chronic inflammatory disease of the digestive tract with systemic manifestations. Etiology is unknown, even if immunological, genetic and environmental factors are involved. The majority of CD patients require surgery during their lifetime due to progressive bowel damage, but, even when all macroscopic lesions have been removed by surgery, the disease recurs in most cases. Postoperative management represents therefore a crucial mean for preventing recurrence. Several drugs and approaches have been proposed to achieve this aim. Endoscopic inspection of the ileocolic anastomosis within 1 year from surgery is widely encouraged, given that endoscopic recurrence is one of the greatest predictors for clinical recurrence. A strategy should be planned only after stratifying patients according to their individual risk of recurrence, avoiding unnecessary therapies when possible benefits are reduced, and selecting high-risk patients for more aggressive intervention.

Is EGFR expression altered following postoperative chemotherapy for colorectal adenocarcinoma?  

PubMed Central

Background There is immunohistochemical evidence to suggest that expression of epidermal growth factor receptor (EGFR) in primary colorectal adenocarcinoma predicts its expression in recurrent disease. This study investigates whether postoperative chemotherapy affects the degree of concordance between EGFR statuses of the two tumors. Methods Thirty-three patients were identified from the files of Sunnybrook Health Sciences Center from July 1994 to June 2005. All patients had resection of their primary tumors and their distant recurrences. Eighteen patients received postoperative chemotherapy, 3 of which also received postoperative radiation therapy. Representative primary and recurrent tumor sections were stained using mouse anti-EGFR antibodies and only membranous staining of malignant cells was recorded. Results were reported as negative (no staining), 1+ (positivity in <50% of cells) or 2+ (positivity in >50% of cells). Results EGFR immunostaining in the 15 patients, who received no postoperative chemotherapy, was decreased in 3 recurrences, remained the same in 10 and increased in 2. In the group of 18 patients who received postoperative chemotherapy, EGFR immunostaining was decreased in 6 recurrences, remained the same in 9 and increased in 3 (p = 0.6598). In patients who received postoperative chemotherapy, the odds ratio for a recurrence to show lower levels of EGFR immunostaining compared to its originally resected primary was 4.75 (CI = 0.94 – 26.73). Conclusion These preliminary data suggest that recurrences following postoperative chemotherapy are likely to have lower levels of EGFR expression compared to cases who receive no chemotherapy. Although the difference of immunostaining profiles between the two groups was not statistically significant, this observation might impact the management of these patients by targeted biologic therapies and its practical implications need further validation in larger series.

A Qualitative Report of Patient Problems and Postoperative Instructions  

PubMed Central

Purpose While surgery related stress may interfere with the patient's ability to concentrate on instructions, language difficulty or low health literacy may also impede appropriate doctor/patient communication. The purpose of this study is to understand from a sample of minority patients the types of problems encountered during healing and the level of information regarding elements of postoperative instructions they recalled receiving at an inner-city safety net hospital. We initiated a qualitative study to understand the care sequence process and provision of informed consent and postoperative instruction. Methods African American or Latino patients, 18 years of age or older, who had third molars removed under general anesthesia or received treatment for a mandibular fracture were recruited to participate in a focus group to discuss their treatment. Patients described their problem and any informed consent given about treatment risks and benefits and postoperative information they recalled. Results A total of 137 former patients were approached, 57 agreed to participate (42%) and 34 of those (60%) completed the interview. Subjects included 14 females and 20 males. Five categories of patient problems were reported: physical, eating, treatment-related, psychosocial, and other problems. People reported 5 categories of coping strategies: medication use, physical treatments, dietary solutions, rest, and clinical assistance. Twenty people recalled being given informed consent, and 5 participants recalled no elements of informed consent. Overall, 14 participants recalled elements of postoperative instruction. Conclusion Gaps in patient understanding of postoperative care suggest room for improvement in postoperative instructions. Additional research is necessary to design and test high-quality postoperative instructions for surgical treatment and recovery in populations with limited health related literacy. PMID:15789315

Postoperative assessment of the patient after transsphenoidal pituitary surgery.  

PubMed

While most transsphenoidal pituitary surgery is accomplished without complication, monitoring is required postoperatively for a set of disorders that are specific to this surgery. Postoperative assessments are tailored to the early and later postoperative periods. In the early period, which spans the first few weeks after surgery, both monitoring of anterior and posterior pituitary function and managing neurosurgical issues are the focus of care. Potential disruption of pituitary-adrenal function is covered with perioperative glucocorticoids. Various strategies exist for ensuring the integrity of this axis, but typically this is done by measuring a morning cortisol on the 2nd or 3rd postoperative days. Patients with levels <10 microg/l should continue therapy with reassessment in the later postoperative period. Monitoring for water imbalances, which are due to deficiency or excess of ADH (DI or SIADH, respectively), is accomplished by continuous accounting of fluid intake, urine output and specific gravities coupled with daily serum electrolyte measurements. DI is characterized by excess volumes of inappropriately dilute urine, which can lead to hypernatremia. Most patients maintain adequate fluid intake and euvolemia, but desmopressin therapy is required for some. SIADH, which peaks in incidence on 7th postoperative day, presents with hyponatremia that can be severe and symptomatic. Management consists of fluid restriction. Neurosurgical monitoring is primarily for disturbances in vision or neurological function, and although uncommon, for CSF leak and infections such as meningitis. In the later postoperative period, the adrenal, thyroid and gonadal axes are assessed. New persistent hypopituitarism is rare when transsphenoidal surgery is performed by an experienced surgeon. Various strategies are available for assessing each axis and for providing replacement therapy in patients with deficiencies. Long term monitoring with assessments of visual, neurological and pituitary function coupled with pituitary imaging is necessary for all patients who have undergone surgery, irrespective of the hormone status of their tumors.

Tycho Brahe - Instrumentenbauer und Meister der Beobachtungstechnik  

NASA Astrophysics Data System (ADS)

Vor der Erfindung des Fernrohrs war der dänische Astronom Tycho Brahe (1546 - 1601) der bedeutendste beobachtende Astronom. Von seinem Observatorium Uraniborg auf der - damals dänischen - Insel Hven ist heute noch der Grundriß erkennbar, von Stjerneborg sind die Fundamente erhalten, die Kuppeln in den 1950er Jahren ergänzt. In der Astronomie-Ausstellung im Deutschen Museum gibt es ein Modell der Sternwarte Uraniborg und der zugehörigen Instrumente (Maßstab 1:10); das größere Modell wurde dem Technischen Museum in Malmö geschenkt. Die Instrumente, die er in den Observatorien Uraniborg und Stjerneborg benutzte, sind nicht erhalten. Aber es gibt gute Beschreibungen der Instrumente (Halbkreis, Quadranten, Sextanten, Armillarsphären, Triquetrum, Himmelsglobus) in seinem Buch Astronomiae instauratae mechanica (Wandsbek 1598). Eine Nachbildung des großen hölzernen Quadranten kann man im Runden Turm in Kopenhagen sehen. Zwei Sextanten, hergestellt für Tycho um 1600 von Jost Bürgi und Erasmus Habermel, gibt es noch im Nationalmuseum für Technik in Prag. Ähnlichkeiten von Tychos Instrumenten mit Groß-Instrumenten aus dem islamischen Kulturkreis sind auffällig. Tycho Brahes Meßgeräte markieren einen großen Fortschritt in der Entwicklung astronomischer Instrumente und Meßtechniken und bilden die Grundlage für den weiteren Fortschritt der Positionsastronomie und der damit verbundenen Tabellenwerke. Die Nachwirkungen sind bis ins 17. und 18. Jahrhundert nachweisbar.

A prospective study on postoperative pain after cataract surgery  

PubMed Central

Purpose To evaluate postoperative pain and early recovery in cataract patients. Patients and methods A total of 201 patients who underwent elective first eye cataract extraction surgery were enrolled, and 196 were included in the final analysis. The study design was a single-center, prospective, follow-up study in a tertiary hospital in eastern Finland. Postoperative pain was evaluated with the Brief Pain Inventory at four time points: at baseline, and at 24 hours, 1 week, and 6 weeks postsurgery. Results Postoperative pain was relatively common during the first hours after surgery, as it was reported by 67 (34%) patients. After hospital discharge, the prevalence decreased; at 24 hours, 1 week, and 6 weeks, 18 (10%), 15 (9%) and 12 (7%) patients reported having ocular pain, respectively. Most patients with eye pain reported significant pain, with a score of ?4 on a pain scale of 0–10, but few had taken analgesics for eye pain. Those who had used analgesics rated the analgesic efficacy of paracetamol and ibuprofen as good or excellent. Other ocular irritation symptoms were common after surgery; as a new postoperative symptom, foreign-body sensation was reported by 40 patients (22%), light sensitivity by 29 (16%), burning by 15 (8%), and itching by 15 (8%). Conclusion Moderate or severe postoperative pain was relatively common after cataract surgery. Thus, all patients undergoing cataract surgery should be provided appropriate counseling on pain and pain management after surgery. PMID:23885165

Early Postoperative Pain After Keyless Abdominal Rope-Lifting Surgery  

PubMed Central

Background and Objectives: Keyless abdominal rope-lifting surgery is a novel, gasless, single-incision laparoscopic surgical technique. In this study we aimed to compare the postoperative pain from keyless abdominal rope-lifting surgery with carbon dioxide laparoscopy performed for benign ovarian cysts. Methods: During a 20-month period, 77 women underwent surgery for a benign ovarian cyst. Keyless abdominal rope-lifting surgery and conventional carbon dioxide laparoscopy techniques were used for the operations in 32 women and 45 women, respectively. The 2 operative techniques were compared with regard to demographic characteristics; preoperative, intraoperative, and postoperative data including early postoperative pain scores; and frequency of shoulder pain and analgesic requirements. Results: Data regarding demographic characteristics, preoperative findings, cyst diameters and rupture rates, intra-abdominal adhesions, intraoperative blood loss, and postoperative hospital stay did not differ between groups (P > .05). However, the mean operative and abdominal access times were significantly longer in the keyless abdominal rope-lifting surgery group (P < .05). Visual analog scale pain scores at initially and at the second, fourth, and 24th hours of the postoperative period were significantly lower in the keyless abdominal rope-lifting surgery group (P < .05). Similarly, keyless abdominal rope-lifting surgery caused significantly less shoulder pain and additional analgesic use (P < .05). Conclusion: Keyless abdominal rope-lifting surgery seems to cause less pain in the management of benign ovarian cysts in comparison with conventional carbon dioxide laparoscopy.

Postoperative coronary artery spasm after mitral valve replacement?  

PubMed Central

Introduction Postoperative coronary artery spasm is an infrequent life-threatening event after cardiac surgery which can occur without an underlying coronary disease Presentation of case We report a documented case of a 67-year-old man with normal coronary arteries submitted to mitral valve replacement. Immediately after surgery he had a ST elevation in the inferior leads, and an inferior wall hypokinesia at the trans-oesophageal echo. A coronary angiography demonstrated a focal spasm in the right coronary artery which was successfully treated by intracoronary injection of nitrates. The following postoperative course was uneventful and the left ventricular function returned to normal. Discussion A coronary artery spasm should be suspected whenever a postoperative infarction occurs after valvular surgery especially in absence of associated coronary artery disease. In this cases postoperative coronary angiography allows both the diagnosis and the treatment. Conclusion This case-report summarizes the findings of this rare and potentially life-threatening cause of early postoperative ischemia and highlights the role of early coronary angiography in the cases of suspected myocardial infarction after cardiac surgery PMID:25680533

Diagnose und Therapie einer Depression im höheren Lebensalter – Einflüsse von Patienten- und Arztmerkmalen  

PubMed Central

Zusammenfassung Studienergebnissee aus dem englischsprachigen Raum zeigen, dass diagnostische und therapeutische Entscheidungen von Hausärzten bei der Versorgung von depressiven Patienten systematischen Einflüssen unterliegen, und dass sowohl Merkmale des Arztes als auch des Patienten unabhängig vom Krankheitsbild Einfluss auf diese Entscheidungen haben. In der vorliegenden Arbeit werden Ergebnisse einer deutschen Studie präsentiert, in der die Einflüsse von Patienten- und Arztmerkmalen auf diagnostische und therapeutische ärztliche Entscheidungen bei einer Depression untersucht wurden. Unter Anwendung eines faktoriellen Experimentaldesigns spielten professionelle Schauspieler in Videofilmen die Rolle von Patienten, die Symptome für eine depressive Erkrankung äußern. In den Videofilmen, die alle auf einem identischen Skript basieren, wurden systematisch die Patientenmerkmale Alter (55 vs. 75 Jahre), Geschlecht und sozialer Status (Hausmeister vs. Lehrer) variiert. Die randomisierte Ärztestichprobe wurde nach dem Arztgeschlecht und professioneller Erfahrung (< 5 vs. > 15 Jahre) geschichtet. Der Videofilm wurde insgesamt 128 niedergelassenen Ärzten für Allgemeinmedizin und hausärztlich tätigen Internisten in ihrer Praxis vorgespielt. Danach wurden die Ärzte zu unterschiedlichen Aspekten von Diagnose und Therapie befragt. Es wurde erhoben, ob der Arzt dem Patienten über das gezeigte Gespräch hinausgehende Fragen stellen würde, welche Diagnosen er für wahrscheinlich hält, wie sicher er sich mit seiner Diagnose ist, welche diagnostischen Tests er anordnen würde, ob er den Patienten überweisen würde oder ob er Medikamente verordnen oder ihm Empfehlungen zur Änderung seines Lebensstils geben würde. Die Ergebnisse weisen darauf hin, dass sowohl die Diagnose als auch die Therapie einer Depression durch niedergelassene Hausärzte in Deutschland nur geringfügig durch die untersuchten Merkmale der Patienten und der behandelnden Ärzte beeinflusst wird.

Perioperative management in order to minimise postoperative delirium and postoperative cognitive dysfunction: Results from a Swedish web-based survey  

PubMed Central

Cognitive side-effects such as emergence agitation (EA), postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are not infrequently complicating the postoperative care especially in elderly and fragile patients. The aim of the present survey was to gain insight regarding concern and interest in prevention and treatment strategies for postoperative delirium and dysfunction, and the use of EEG-based depth-of-anaesthesia monitoring possibly reducing the risk for cognitive side effects among anaesthesia personnel. Methods A web-based validated questionnaire was sent to all Swedish anaesthesiologists and nurse anaesthetists during summer 2013. The questionnaire consisted of 3 sections, subjective preferences, routines and practices related to the perioperative handling of EA, POD, POCD. Results The response rate was 52%. Cardiovascular/pulmonary risks where assessed as importance by 98, 97% of responders while 69% considered the risk of neurocognitive side-effects important. When asked explicitly around cognitive side-effects 89%, 37% and 44% assessed awareness, POC and POD respectively of importance. EEG-based depth-of-anaesthesia monitors were used in 50% of hospitals. The responders were not convinced about the benefits of such monitors even in at-risk patients. Structured protocols for the management of postoperative cognitive side-effects were available only in few hospitals. Conclusion Swedish anaesthesia personnel are concerned about the risk of postoperative cognitive side-effects but are more concerned about cardiovascular/pulmonary risks, pain, PONV and the rare event of awareness. Most respondents were not convinced about the use of depth-of-anaesthesia monitors. There is a need to improve knowledge around risk factors, prevention and management of postoperative cognitive side effects. PMID:25568795

Magnesium Can Decrease Postoperative Physiological Ileus and Postoperative Pain in Major non Laparoscopic Gastrointestinal Surgeries: A Randomized Controlled Trial  

PubMed Central

Background Magnesium is an antagonist of (N-methyl D-Aspartate) NMDA receptor and its related canals, and may affect perceived pain. Objectives The aim of this study was to evaluate the impact of intravenous magnesium on the hemodynamic parameters, analgesic consumption and ileus. Patients and Methods A randomized, double blind, placebo controlled study was performed. Thirty two patients of ASA I or II, scheduled for major gastrointestinal (GI) surgery, were divided into magnesium and control groups. Magnesium group received a bolus of 40 mg/kg of magnesium sulphate, followed by a continuous perfusion of 10 mg/kg/h for the intraoperative hours. Postoperative analgesia was ensured by Morphine patient–controlled analgesia (PCA). The patients were evaluated by Intraoperative hemodynamic parameters, the postoperative pain by numeral rating scale (NRS), and the total dose of intraoperative and postoperative analgesic consumption. Postoperative hemodynamic, respiratory parameters, physiological gastrointestinal obstruction (ileus), and side effects were also recorded. Results The study included 14 males and 18 females. Age range of patients was 17 to 55 years old. The average age in the magnesium group was 41.33 ± 10.06 years and45.13 ± 11.74 years in control group. Mean arterial pressure (MAP) of magnesium group decreased during the operation but increased in control group (P < 0.001), and systemic vascular resistance (SVR) of magnesium group decreased during the operation also (P < 0.02) but increased in control group. Postoperative cumulative Morphine consumption in magnesium group, was significantly in lower level (P = 0.026). For NRS, severe pain was significantly lower, in magnesium group, at all intervals of postoperative evaluations, but moderate and mild pain were not lower significantly. Duration of postoperative ileus was 2.3 ± 0.5 days in magnesium group, and 4.2 ± 0.6 days in control group (P = 0.01). Conclusions Intravenous magnesium reduces postoperative ileus, postoperative severe pain and intra/post operative analgesic requirements in patients after major GI surgery. No side effects of magnesium in these doses were seen, so it seems to be beneficial along with routine general anesthesia in major GI surgeries. PMID:24660146

Neonatal Blalock-Taussig shunt: technical aspects and postoperative management.  

PubMed

A systemic-pulmonary artery shunt in neonates with decreased pulmonary blood flow is technically demanding. We describe our surgical technique, postoperative management, and results in 19 neonates who underwent a modified Blalock-Taussig shunt between April 2003 and March 2006. Prostaglandin infusion was required in 8 patients who were critically cyanosed, and 5 were on inotropic support preoperatively. A 3.5 or 4.0-mm polytetrafluoroethylene graft was anastomosed with 8/0 polypropylene suture. Postoperatively, systemic pressure was kept slightly higher than normal, and heparin was started early. One patient required revision of the shunt, and one was reexplored for bleeding. There were 2 hospital deaths (mortality, 11%) in patients with preoperative hemodynamic instability. The mean follow-up period was 12 months, with no late postoperative shunt blockage or death. Meticulous surgical technique and judicious use of heparin and inotropic agents improved the outcome and reduced the incidence of shunt blockage and reexploration for bleeding. PMID:18245697

[Postoperative management of patients with BMI > 40 kg / m2].  

PubMed

Bariatric surgery, especially in the morbidly obese, can be associated with serious postoperative problems. Apart from surgical complications requiring reoperation, pre-existing disease can worsen during the postoperative period. Bariatric patients require particular therapeutic approaches such as adapted fluid and pain management, management of obstructive sleep apnoea-hypopnea, early ambulation and measures for preventing pressure ulcers. Another challenging issue is the early identification and management of postoperative intraabdominal sepsis (IAS) before the onset of organ dysfunction. Early and frequent ambulation is thought to reduce risk of pressure ulcers, deep vein thrombosis, resedation, pain, pneumonia and atelectasis. To prevent spine injury of health care workers it is necessary to provide appropriate support with special beds, lifting and transfer devices. PMID:19242882

The use of postoperative suction drainage in total knee arthroplasty.  

PubMed

A retrospective review of 299 total knee arthroplasties performed between 1973 and 1983 revealed 170 knees in which postoperative suction drainage was used and 129 knees in which drains were not used. Comparison between these two groups revealed no statistically significant difference in wound problems, postoperative temperatures, or resulting range of motion. However, blood transfusions were given more than twice as often to the patients whose knees were drained (39% compared to 16%, p less than .01). The drained group also had a greater decrease in hemoglobin than the nondrained group (3.1 gm compared to 2.6 gm, p less than .01). In a review of these patients, no advantage was found for the use of postoperative suction drainage in the uncomplicated total knee arthroplasty. PMID:3720129

Flurbiprofen axetil reduces postoperative sufentanil consumption and enhances postoperative analgesic effects in patients with colorectal cancer surgery  

PubMed Central

To investigate the effects of different strategies of flurbiprofen axetil (FA) administration on postoperative pain and sufentanil (SF) consumption after open colorectal cancer (CRC) surgery. Forty patients undergoing elective CRC resection were divided into two groups (n = 20 each). Patients in the F50+50 group received 50 mg of intravenous FA 30 min before skin incision and six hours after the first dose; patients in the F100 group received 100 mg of intravenous FA 30 min before skin incision. Perioperative plasma FA (CFA) and SF concentrations (CSF) were determined. Analgesic and sedative efficacy were evaluated using the visual analogue scale (VAS), Bruggman Comfort Scale (BCS), and Ramsay sedation scale. The time to the first PCIA trigger, the number of patients that pressed the PCIA trigger within 24 h after surgery, and the cumulative doses of SF consumption within 6 and 24 h after surgery were recorded. At postoperative 6 and 24 h, CFA was significantly higher, CSF was significantly lower, and the number of patients that pressed the PCIA trigger and the consumption of SF were significantly lower in the F50+50 group compared with the F100 group. At postoperative 4 h, VAS and BCS were significantly lower in the F50+50 group compared with the F100 group (P < 0.05). An administration strategy that maintains a relatively high plasma FA concentration at 6-24 h post-operatively may reduce postoperative inflammatory pain and SF-requirement in patients undergoing CRC resection.

Association of Preoperative Biliary Drainage With Postoperative Outcome Following Pancreaticoduodenectomy  

PubMed Central

Objective To determine whether preoperative biliary instrumentation and preoperative biliary drainage are associated with increased morbidity and mortality rates after pancreaticoduodenectomy. Summary Background Data Pancreaticoduodenectomy is accompanied by a considerable rate of postoperative complications and potential death. Controversy exists regarding the impact of preoperative biliary instrumentation and preoperative biliary drainage on morbidity and mortality rates after pancreaticoduodenectomy. Methods Two hundred forty consecutive cases of pancreaticoduodenectomy performed between January 1994 and January 1997 were analyzed. Multiple preoperative, intraoperative, and postoperative variables were examined. Pearson chi square analysis or Fisher’s exact test, when appropriate, was used for univariate comparison of all variables. Logistic regression was used for multivariate analysis. Results One hundred seventy-five patients (73%) underwent preoperative biliary instrumentation (endoscopic, percutaneous, or surgical instrumentation). One hundred twenty-six patients (53%) underwent preoperative biliary drainage (endoscopic stents, percutaneous drains/stents, or surgical drainage). The overall postoperative morbidity rate after pancreaticoduodenectomy was 48% (114/240). Infectious complications occurred in 34% (81/240) of patients. Intraabdominal abscess occurred in 14% (33/240) of patients. The postoperative mortality rate was 5% (12/240). Preoperative biliary drainage was determined to be the only statistically significant variable associated with complications (p = 0.025), infectious complications (p = 0.014), intraabdominal abscess (p = 0.022), and postoperative death (p = 0.037). Preoperative biliary instrumentation alone was not associated with complications, infectious complications, intraabdominal abscess, or postoperative death. Conclusions Preoperative biliary drainage, but not preoperative biliary instrumentation alone, is associated with increased morbidity and mortality rates in patients undergoing pancreaticoduodenectomy. This suggests that preoperative biliary drainage should be avoided whenever possible in patients with potentially resectable pancreatic and peripancreatic lesions. Such a change in current preoperative management may improve patient outcome after pancreaticoduodenectomy. PMID:10450725

Postoperative risk following uvulopalatopharyngoplasty for obstructive sleep apnea.  

PubMed

A study was conducted to assess oxygenation and respiratory changes on the first and second postoperative nights after uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnea (OSA). Twelve patients were postoperatively evaluated with 8-hour nocturnal polysomnography on four occasions: (1) PREOP--night before UPPP, (2) POPN1--first postoperative night, (3) POPN2--second postoperative night, and (4) 3MOS--3-month follow-up study. Results demonstrate that apnea index (AI) and respiratory disturbance index (RDI) were significantly improved at 3MOS from PREOP levels: AI (p less than 0.01) and RDI (p less than 0.05). There were no statistical differences from PREOP to POPN1 or POPN2 for AI, RDI, lowest oxyhemoglobin saturation (LSAT), or number of desaturations (#DESAT). One of twelve patients dropped LSAT greater than 10% from PREOP to POPN1 or POPN2 (82% PREOP to 71% POPN2). Patients were grouped by PREOP LSAT greater than or equal to 80% or less than 80%, and the postoperative change in LSAT was evaluated by comparing PREOP to a value averaging POPN1 and POPN2. Patients with LSAT greater than or equal to 80% decreased by 2.6%; patients with LSAT less than 80% improved by 6.2%. This change in LSAT between groups was statistically different (p = 0.02). These data suggest that in the majority of patients, preoperative indices remain unchanged for at least 2 days after surgery, even for patients who demonstrated improvement at 3 months. However, worsening does occur in some patients. On the basis of the results of this study and clinical experience with the postoperative course, a selective management protocol is outlined.

Delayed-onset postoperative endophthalmitis secondary to Exophiala.  

PubMed

Exophiala is a genus of slow-growing, melanin-producing, saprophytic fungi most commonly found in soil, faeces and decaying plant matter. It is an unusual fungal pathogen capable of causing a variety of ophthalmic manifestations, including keratitis, scleritis and endophthalmitis. In this report, we present a rare case of delayed-onset postoperative endophthalmitis confined to the anterior segment, secondary to Exophiala species. Previous reported cases of delayed-onset postoperative endophthalmitis have been treated medically, with suboptimal outcomes. Our experience supports the use of anterior segment surgery to clear the nidus of disease combined with intravitreal voriconazole to prevent recurrence of the infection. PMID:25691581

Acoustic neuroma: postoperative vertigo and the mechanisms of compensation.  

PubMed

Ninety-five percent of patients with acoustic neuroma experience some degree of vertigo preoperatively, postoperatively or both. Postoperative vertigo is often a debilitating condition that results when the eighth cranial nerve is severed during surgery to resect a tumor growing around the vestibular portion of this nerve. Thus, surgery for acoustic neuroma affects the membranous labyrinth, which is the functional part of the vestibular apparatus and is primarily concerned with equilibrium. Compensation for impaired equilibrium may be by biofeedback in the vestibular pathways, visual control, exercise or drug therapy. Nurses can significantly influence the recovery of acoustic neuroma patients by encouraging and reinforcing exercise and other mechanisms of vestibular compensation. PMID:1517665

Herstellung von Chitosan und einige Anwendungen  

NASA Astrophysics Data System (ADS)

1. Die Deacetylierung von crabshell - Chitosan führte gleichzeitig zu einem drastischen Abfall der mittleren viscosimetrischen Molmasse ( Mv), insbesondere wenn die Temperatur und die Konzentration an NaOH erhöht werden. Diese Parameter beeinflussten jedoch nicht den Grad der Deacetylierung (DD). Wichtig ist jedoch die Quelle des Ausgangsmaterials: Chitin aus Pandalus borealis ist ein guter Rohstoff für die Herstellung von Chitosan mit niedrigem DD und gleichzeitig hoher mittlerer Mv, während Krill-Chitin (Euphausia superba) ein gutes Ausgangsmaterial zur Herstellung von Chitosan mit hohem DD und niedrigem Mv ist. Chitosan, das aus Insekten (Calliphora erythrocephala), unter milden Bedingungen (Temperatur: 100°C, NaOH-Konzentration: 40 %, Zeit: 1-2h ) hergestellt wurde, hatte die gleichen Eigenschaften hinsichtlich DD und Mv wie das aus Krill hergestellte Chitosan. Der Bedarf an Zeit, Energie und NaOH ist für die Herstellung von Insekten-Chitosan geringer als für crabshell-Chitosan vergleichbare Resultaten für DD und Mv. 2. Chitosan wurde durch den Schimmelpilz Aspergillus fumigatus zu Chitooligomeren fermentiert. Die Ausbeute beträgt 25%. Die Chitooligomere wurden mit Hilfe von HPLC und MALDI-TOF-Massenspektrmetrie identifiziert. Die Fermentationsmischung fördert die Immunität von Pflanzen gegen Bakterien und Virusinfektion. Die Zunahme der Immunität schwankt jedoch je nach System Pflanze-Pathogen. Die Fermentation von Chitosan durch Aspergillus fumigatus könnte eine schnelle und billige Methode zur Herstellung von Chitooligomeren mit guter Reinheit und Ausbeute sein. Eine partiell aufgereinigte Fermentationsmischung dieser Art könnte in der Landwirtschaft als Pathogeninhibitor genutzt werden. Durch kontrollierte Fermentation, die Chitooligomere in definierter Zusammensetzung (d.h. definierter Verteilung des Depolymerisationsgrades) liefert, könnte man zu Mischungen kommen, die für die jeweilige Anwendung eine optimale Bioaktivität besitzen. 3. Die aus Chitosan-Dispersionen hergestellten MCChB-Filme weisen bessere mechanische Eigenschaften (Bruchfestigkeit, Dehnung) und eine höhere Wasseraufnahmefähigkeit auf als Filme, die nach herkömmlichen Methoden aus sauerer Lösung hergestellt werden. Die Einführung von Proteinen ändert die mechanischen Eigenschaften der MCChB-Filme abhängig von der Art, der Proteine sowie des DD und der Mv des eingesetzte Chitosan. Die Zugabe von Protein beschleunigt den biologischen Abbau der MCChB-Filme. Aus den untersuchten MCChB-Filmen mit Proteinzusatz können leichte, reißfeste und dennoch elastische Materialen hergestellt werden. 4. Mit Hilfe von MCChB-Dispersion kann Papier modifiziert werden. Dadurch werden die mechanischen Eigenschaften verbessert und die Wasseraufnahme wird verringert. Die Zugabe von Proteinen verringert das Wasseraufnahmevermögen noch weiter. Ein geringes Wasseraufnahmevermögen ist der bedeutendste Faktor bei der Papierherstellung. Auch Papier, das mit einem MCChB-Protein-Komplexe modifiziert wurde, zeigt gute mechanische Eigenschaften. 5. Wird Chitosan durch unmittelbare Einführung von MCChB auf Cellulose-Fasern aufgebracht, so erhält man eine netzartige Struktur, während durch Ausfällung aufgebrachtes Chitosan eine dünne Schicht auf den Cellulose-Fasern bildet. Die netzartige Struktur erleichtert die Bioabbaubarkeit, während die Schichtstruktur diese erschwert. 6. Die guten mechanischen Eigenschaften, die geringe Wasseraufnahmefähigkeit und die mit Cellulose vergleichbare Bioabbaubarkeit von Papier, das mit MCChB modifiziert wurde, lassen MCChB für die Veredlung von Papier nützlich erscheinen. 1. Deacetylation of the crustacean chitosan causes drastically decrease in the Mv with increasing reaction temperature and time as well as the concentration of sodium hydroxide. However, the DD are relatively less affected. Pandalus borealis is a good source for production of chitosan having high Mv and low DD, whereas chitosan of medium to low Mv can ideally be prepared using krill chitin. Insect chitosan is prepared under milder condition a

Postoperative anatomic and pathologic findings at CT following gastrectomy.  

PubMed

Helical computed tomography (CT) is useful in identifying postoperative anatomic changes, complications, and tumor recurrence in gastric cancer patients who have undergone gastrectomy. Postoperative anatomic changes can usually be identified on consecutive CT scans. Complications include anastomotic leakage, duodenal stump leakage, intraabdominal bleeding, wound complications, and other less common complications (postoperative pancreatitis, retention of surgical foreign bodies, diffuse peritonitis). The degree and extent of bowel wall thickening is important in diagnosing tumor recurrence; however, CT lacks specificity. Large or conglomerated lymph node metastases can be easily diagnosed at CT; however, small solitary or focal metastases may not be detected or differentiated from nonmetastatic nodes. Ascites, a common finding with peritoneal seeding in gastrointestinal tumors, is well depicted at CT. Hematogenous metastases from gastric carcinoma are most frequently seen in the liver and are best demonstrated with helical CT performed during the portal venous phase of enhancement (sensitivity >90% for the detection of lesions >1 cm). The sophisticated surgical procedures used in gastrectomy can alter normal anatomy and make image interpretation difficult; thus, familiarity with the appearance of postoperative anatomic changes, complications, and tumor recurrence is essential for accurate CT evaluation of affected patients.

Post-Operative Pain After Knee Arthroscopy and Related Factors  

PubMed Central

The aim of this study was to explore the intensity of post-arthroscopy knee pain during the first 24 hours, and to study the influence of pre-operative pain, tourniquet time and amount of surgical trauma on post-arthroscopy pain. In 78 male patients that underwent elective arthroscopic menisectomy or diagnostic arthroscopy of the knee, preoperative and post-operative pain were registered using the Visual Analogue Scale. Variance for repeated measures and for independent observations was analysed. Supplementary analgesia was required for 23% of the patients, more often in the recovery room and between 2 and 8 hours postoperatively. Of all factors analyzed, only time was statistically significant in determining the level of post-operative pain. Supplementary analgesia was required only in patients that underwent operative arthroscopy, and more often in patients with tourniquet time of more than 40 minutes. In conclusions, post-operative time is the most significant factor related to the post-arthroscopy knee pain. PMID:19478890

[Risk assessment, prophylaxis and treatment for postoperative nausea and vomiting].  

PubMed

The incidence of postoperative nausea and vomiting in the general population has been estimated to have remained constant at around 20% to 30% in recent years, but it can reach 80% in high-risk patients. A wide range of risk factors related to patient variables, anesthetic technique, or surgery have been described. However, risk can be classified by taking only 4 factors into consideration: female gender, nonsmoker, a history of motion sickness or postoperative vomiting, and use of opioids for postoperative analgesia. Antiemetic prophylaxis is not recommended for patients at low-risk (only 1 risk factor or none). Considering prophylaxis is recommended for patients at moderate risk (2 risk factors). For patients at high risk (3 or 4 risk factors), prophylaxis should be provided with 4 mg of intravenous ondansetron 30 minutes before ending surgery, 4 mg of intravenous dexamethasone at anesthetic induction, or both. Besides medical prophylaxis, strategies for lowering underlying risk are recommended: use regional anesthesia whenever possible, use total intravenous anesthesia with propofol if regional anesthesia is impossible, keep opioid and neostigmine use to a minimum, and try to maintain adequate hydration during surgery. Once preventive measures are taken, therapeutic options are limited and the management of postoperative nausea and vomiting, once established, is difficult. PMID:16827070

Wnt-Signalwege bei kutaner Homöostase und Pathologie.  

PubMed

Die Säugerhaut stellt die primäre Grenzfläche zwischen Körper und externer Umwelt dar und ist zugleich die erste Abwehrlinie gegen Pathogene, mechanische Traumata, Schädigungen durch Sonnenlicht und chemische Belastungen. Um die Barrierefunktion aufrechtzuerhalten, ist ein einwandfreier physischer, biochemischer und immunologischer Zustand der Haut nötig. Die Haut ist also ein komplexes, dynamisches Organ mit hohem zellulärem Turnover während der normalen Gewebeerneuerung und Wundheilung. Stammzellreservoirs garantieren die konstante Erneuerung der Haut. Der Wnt-Signalweg kontrolliert den Stammzellenerhalt sowie Entscheidungen bezüglich des Zellschicksals in verschiedenen Geweben und spiegelt einen zentralen Pfad in der Kontrolle von Hautentwicklung und Homöostase wieder. Die Unterbrechung des Wnt-Signalweges in der Haut verursacht Erkrankungen wie Alopezie, chronisch inflammatorische Hauterkrankungen oder Krebs.

Respiratory physiotherapy in the pre and postoperative myocardial revascularization surgery.  

PubMed

The cardiovascular diseases are among the main death causes in the developed world. They have been increasing epidemically in the developing countries. In spite of several alternatives for the treatment of the coronary artery disease; the surgery of the myocardial revascularization is an option with proper indications of medium and long-term with good results. It provides the remission of the angina symptoms contributing to the increase of the expectation and improvement of the life quality. Most of patients undergoing myocardial revascularization surgery develop postoperative lung dysfunction with important reduction of the lung volumes, damages in the respiratory mechanism, decrease in the lung indulgence and increase of the respiratory work. The reduction of volumes and lung capacities can contribute to alterations in the gas exchanges, resulting in hypoxemia and decrease in the diffusion capacity. Taking this into account, the Physiotherapy has been requested more and more to perform in the pre as well as in the postoperative period of this surgery. This study aimed at updating the knowledge regarding the respiratory physiotherapy performance in the pre and postoperative period of the myocardial revascularization surgery enhancing the prevention of lung complications. The Physiotherapy uses several techniques in the preoperative period; such as: the incentive spirometry, exercises of deep breathing, cough, inspiratory muscle training, earlier ambulation and physiotherapeutic orientations. While in the postoperative period, the objective is the treatment after lung complications took place, performed by means of physiotherapeutic maneuvers and noninvasive respiratory devices, aiming at improving the respiratory mechanism, the lung reexpansion and the bronchial hygiene. Respiratory physiotherapy is an integral part in the care management of the patient with cardiopathy, either in the pre or in the postoperative period, since it contributes significantly to a better prognosis of these patients with the use of specific techniques.

Predictors of Postoperative Complications After Trimodality Therapy for Esophageal Cancer  

SciTech Connect

Purpose: While trimodality therapy for esophageal cancer has improved patient outcomes, surgical complication rates remain high. The goal of this study was to identify modifiable factors associated with postoperative complications after neoadjuvant chemoradiation. Methods and Materials: From 1998 to 2011, 444 patients were treated at our institution with surgical resection after chemoradiation. Postoperative (pulmonary, gastrointestinal [GI], cardiac, wound healing) complications were recorded up to 30 days postoperatively. Kruskal-Wallis tests and ?{sup 2} or Fisher exact tests were used to assess associations between continuous and categorical variables. Multivariate logistic regression tested the association between perioperative complications and patient or treatment factors that were significant on univariate analysis. Results: The most frequent postoperative complications after trimodality therapy were pulmonary (25%) and GI (23%). Lung capacity and the type of radiation modality used were independent predictors of pulmonary and GI complications. After adjusting for confounding factors, pulmonary and GI complications were increased in patients treated with 3-dimensional conformal radiation therapy (3D-CRT) versus intensity modulated radiation therapy (IMRT; odds ratio [OR], 2.018; 95% confidence interval [CI], 1.104-3.688; OR, 1.704; 95% CI, 1.03-2.82, respectively) and for patients treated with 3D-CRT versus proton beam therapy (PBT; OR, 3.154; 95% CI, 1.365-7.289; OR, 1.55; 95% CI, 0.78-3.08, respectively). Mean lung radiation dose (MLD) was strongly associated with pulmonary complications, and the differences in toxicities seen for the radiation modalities could be fully accounted for by the MLD delivered by each of the modalities. Conclusions: The radiation modality used can be a strong mitigating factor of postoperative complications after neoadjuvant chemoradiation.

Single dose oral meloxicam for acute postoperative pain in adults  

PubMed Central

Background Meloxicam is a non-steroidal anti-inflammatory drug (NSAID) used mainly in treating pain associated with arthritis. The usual oral dose for osteoarthritis is 15 mg daily, but lower doses of 7.5 mg are advised in older patients. This review sought to evaluate the efficacy and safety of oral meloxicam in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties. Objectives To assess the efficacy of single dose oral meloxicam in acute postoperative pain, and any associated adverse events. Search methods We searched Cochrane CENTRAL (Issue 2, 2009), MEDLINE (June 2009); EMBASE (June 2009); the Oxford Pain Relief Database. Selection criteria Randomised, double-blind, placebo-controlled clinical trials of oral meloxicam for relief of acute postoperative pain in adults. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We planned to use area under the “pain relief versus time” curve to derive the proportion of participants with meloxicam experiencing least 50% pain relief over 4 to 6 hours, using validated equations; to use number needed to treat to benefit (NNT); the proportion of participants using rescue analgesia over a specified time period; time to use of rescue analgesia; information on adverse events and withdrawals. Main results No studies were identified by the searches that examined oral meloxicam in patients with established postoperative pain. Authors’ conclusions In the absence of evidence of efficacy, at present, for oral meloxicam in acute postoperative pain, its use in this indication is not justified. Because trials clearly demonstrating analgesic efficacy in the most basic of acute pain studies is lacking, use in other indications should be evaluated carefully. Given the large number of available drugs of this and similar classes, there is no urgent research agenda. PMID:19821429

Preoperative anemia increases postoperative morbidity in elective cranial neurosurgery  

PubMed Central

Background: Preoperative anemia may affect postoperative mortality and morbidity following elective cranial operations. Methods: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was used to identify elective cranial neurosurgical cases (2006-2012). Morbidity was defined as wound infection, systemic infection, cardiac, respiratory, renal, neurologic, and thromboembolic events, and unplanned returns to the operating room. For 30-day postoperative mortality and morbidity, adjusted odds ratios (ORs) were estimated with multivariable logistic regression. Results: Of 8015 patients who underwent elective cranial neurosurgery, 1710 patients (21.4%) were anemic. Anemic patients had an increased 30-day mortality of 4.1% versus 1.3% in non-anemic patients (P < 0.001) and an increased 30-day morbidity rate of 25.9% versus 14.14% in non-anemic patients (P < 0.001). The 30-day morbidity rates for all patients undergoing cranial procedures were stratified by diagnosis: 26.5% aneurysm, 24.7% sellar tumor, 19.7% extra-axial tumor, 14.8% intra-axial tumor, 14.4% arteriovenous malformation, and 5.6% pain. Following multivariable regression, the 30-day mortality in anemic patients was threefold higher than in non-anemic patients (4.1% vs 1.3%; OR = 2.77; 95% CI: 1.65-4.66). The odds of postoperative morbidity in anemic patients were significantly higher than in non-anemic patients (OR = 1.29; 95% CI: 1.03-1.61). There was a significant difference in postoperative morbidity event odds with a hematocrit level above (OR = 1.07; 95% CI: 0.78-1.48) and below (OR = 2.30; 95% CI: 1.55-3.42) 33% [hemoglobin (Hgb) 11 g/dl]. Conclusions: Preoperative anemia in elective cranial neurosurgery was independently associated with an increased risk of 30-day postoperative mortality and morbidity when compared to non-anemic patients. A hematocrit level below 33% (Hgb 11 g/dl) was associated with a significant increase in postoperative morbidity. PMID:25422784

Single dose oral nabumetone for acute postoperative pain in adults  

PubMed Central

Background Nabumetone is a non-steroidal anti-inflammatory drug (NSAID) used mainly in treating pain associated with arthritis. The usual oral dose for osteoarthritis is 1000 mg daily, and higher doses are not advised in older patients. There are no known systematic reviews of its analgesic efficacy in acute postoperative pain. This review sought to evaluate the efficacy and safety of oral nabumetone in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish whether drugs have analgesic properties. Objectives To assess the efficacy of single dose oral nabumetone in acute postoperative pain, and any associated adverse events. Search methods We searched The Cochrane Library (Issue 2, 2009), MEDLINE (May 2009); EMBASE via Ovid (May 2009); and the Oxford Pain Relief Database. Selection criteria Randomised, double-blind, placebo-controlled clinical trials of oral nabumetone for relief of acute postoperative pain in adults. Data collection and analysis Two review authors independently assessed trial quality and extracted data. The area under the “pain relief versus time” curve was used to derive the proportion of participants with nabumetone and placebo experiencing at least 50% pain relief over 4 to 6 hours, using validated equations. The number needed to treat to benefit (NNT) was calculated using 95% confidence intervals (CI). The proportion of participants using rescue analgesia over a specified time period, and time to use of rescue analgesia, were sought as additional measures of efficacy. Information on adverse events and withdrawals was also collected. Main results No studies were identified by the searches that examined oral nabumetone in participants with established postoperative pain. Authors’ conclusions In the absence of evidence of efficacy, at present, for oral nabumetone in acute postoperative pain, its use in this indication is not justified. Because trials clearly demonstrating analgesic efficacy in the most basic of acute pain studies is lacking, use in other indications should be evaluated carefully. Given the large number of available drugs of this and similar classes, there is no urgent research agenda. PMID:19821428

Presurgical orthopedic treatment ameliorates postoperative nasal deformity after cheiloplasty.  

PubMed

We assessed the postoperative nasal form and symmetry after presurgical use of a Hotz plate (HP) in patients with unilateral complete cleft lip and palate (UCLP). The subjects were 28 infants with UCLP who underwent cheiloplasty. Of these subjects, 14 underwent presurgical orthopedic treatment using the HP (HP group) and 14 underwent the same treatment without the HP (non-HP group). Photographic records were obtained 1 and 6 months after cheiloplasty, and the results of anthropometric analysis were compared between the 2 groups. The nasal inclination and the ratio of the width of the nasal base to the total width of the nose were significantly improved in the HP group compared with the non-HP group at both postoperative time points. Thus, presurgical use of the HP significantly improved the nasal asymmetry and deformity in UCLP patients after primary cheiloplasty and nasal repair. PMID:23123612

Prevention and management of postoperative nausea and vomiting in adults.  

PubMed

In early 2007, patients at our small community hospital's outpatient surgery center experienced postoperative nausea and postoperative nausea and vomiting (PONV) at a rate of 27% to 35%. Many record reviews and a written survey of nurses in the postanesthesia care unit and same day surgery center revealed that little or no risk assessment and no consistent prophylaxis or treatment were in use by nurses, physicians, or anesthesia care providers. After a review of the literature and discussions with anesthesia care providers, we developed and put into practice a risk assessment tool and perioperative care path. A formal evaluation to assess the effectiveness of the plan was performed one year after implementation. We found that the rates of PONV had decreased to 16%. AORN J 90 (September 2009) 391-413.

A Case of Postoperative Tuberculous Spondylitis with a Bizarre Course  

PubMed Central

Postoperative infections following spine surgery are usually attributable to bacterial organisms. Staphylococcus aureus is known to be the most common single pathogen leading to this infection, and the number of infections caused by methicillin-resistant Staphylococcus aureus is increasing. However, there is a paucity of literature addressing postoperative infection with Mycobacterium tuberculosis. We encountered a case of tuberculous spondylitis after spine surgery. A man had fever with low back pain three weeks after posterior interbody fusion with instrumentation for a herniated intervertebral disc at the L4-L5 level. He had been treated with antibiotics for an extended period of time under the impression that he had a bacterial infection, but his symptoms and laboratory data had not improved. Polymerase chain reaction for Mycobacterium tuberculosis turned out to be positive. The patient's symptoms finally improved when he was treated with antituberculosis medication. PMID:19884999

Anxiety and Postoperative Recovery in Ambulatory Surgery Patients  

PubMed Central

There has been a growing trend toward one-day ambulatory surgery. Unfortunately, there has been little research evaluating how patients recover at home after one-day surgery. This study examined the relationship between preoperative anxiety and postoperative recovery in ambulatory surgery patients. Fifty women who were scheduled for a laparascopy completed a series of questionnaires on the day before surgery and on each of three days after surgery. One month after surgery, the patients were telephoned and reported on their recovery. The surgeon rated each patient on their estimated degree of anxiety and length of recovery. The results showed that preoperative anxiety partially predicted the patients' psychological and physiological reaction to surgery. Identification of those patients who show high anxiety and distress may help to prevent postoperative complications. These patients may benefit from patient education and psychological interventions to decrease their fears and anxiety and they may benefit from more intensive observation periods following their surgery.

Cohort Study of Intracameral Moxifloxacin in Postoperative Endophthalmitis Prophylaxis  

PubMed Central

We conducted a cohort study to evaluate post-cataract surgery endophthalmitis rates in relation to prophylactic intracameral moxifloxacin administration. A total of 2332 patients (2674 eyes) who underwent phacoemulsification by a single surgeon from January 2007 through December 2012 were included in the study. A total of 1056 eyes did not receive intracameral prophylactic moxifloxacin and the antibiotic was injected in 1618 eyes. The incidence of presumed postoperative endophthalmitis in the 2 groups was calculated. The rate of presumed infectious endophthalmitis after cataract surgery between January 2007 and June 2009 (without intracameral moxifloxacin) was 0.094%. The rate in the second period, from July 2009 to December 2012 (with prophylactic intracameral moxifloxacin), was 0%. In our patients, a decline in the incidence of presumed infectious postoperative endophthalmitis appeared to be associated with the application of intracameral moxifloxacin. PMID:24526838

Percutaneous drainage of postoperative abdominal and pelvic lymphoceles.  

PubMed

Eleven patients with postoperative abdominal and pelvic lymphoceles underwent percutaneous diagnostic and therapeutic intervention with either needle aspiration or catheter drainage. Although initial sonographic or CT examinations accurately identified these collections, definitive diagnosis required fluid sampling and laboratory analysis for confirmation. Seven pelvic and two retroperitoneal lymphoceles demonstrated a gross appearance and composition different from two lymphatic collections in the upper peritoneum. Nine patients underwent catheter drainage; two were managed by needle aspiration alone. Duration of catheter drainage was 4-120 days, substantially longer than is customary for standard fluid collections. Nine of 11 patients were cured by percutaneous aspiration or drainage alone. Bacterial colonization developed in three persistently draining lymphoceles. However, no clinical sepsis or bacteremia occurred. In another patient with persistent high-volume lymphatic output, sclerotherapy with tetracycline instillation was successful in rapidly closing the lymphatic fistula. Percutaneous drainage is a safe, effective procedure for drainage of postoperative lymphoceles. PMID:3901705

Pancoast tumors: improved survival with preoperative and postoperative radiotherapy  

SciTech Connect

Long-term survival after treatment of Pancoast tumors has been limited in most series to those patients without positive lymph nodes or residual tumor. In our series of 18 consecutive patients treated with preoperative irradiation and resection, 14 underwent supplemental postoperative radiotherapy because of positive lymph nodes, tumor at the resection margin, or both. No hospital deaths occurred. Eight patients subsequently died, 6 because of metastatic disease; only 2 deaths were secondary to local recurrence. Ten patients are alive at 6 months to 13 years after resection, and 9 of the 10 have no evidence of tumor recurrence. The overall five-year observed survival (Kaplan-Meier) for the entire series was 56.1 +/- 12.7% (+/- standard error). Although the number of patients is small, the addition of postoperative radiotherapy for those with unfavorable operative findings resulted in long-term survival comparable to that of patients with negative nodes and margins.

Postoperative pain: acupuncture versus percutaneous electrical nerve stimulation.  

PubMed

The purpose of this study was to examine the effect of traditional acupuncture compared with acupuncture with percutaneous electrical nerve stimulation (PENS) on postoperative surgical pain relief in gynecologic oncology patients. Twenty postoperative gynecologic oncology patients were randomly assigned into the two groups, and the intervention was initiated within 24 hours after surgery. The patients in each group received four treatments in the subsequent 48 hours, with 12 hours between each treatment. Either traditional acupuncture needles or acupuncture needles with a pulsed electric current were applied to stimulate the area of points Sp6 and Sp8 near the saphenous nerve. Pain measurement instruments included a visual analog scale and the McGill Pain Questionnaire. Although the PENS treatment group demonstrated a consistent decrease in pain with each treatment application compared with the traditional acupuncture group, after 48 hours both groups experienced equivalent pain relief.

Effectiveness of preoperative analgesics on postoperative dental pain: a study.  

PubMed Central

Patients undergoing extractions of third molar teeth under general anesthesia were given a placebo, diclofenac (a nonsteroidal anti-inflammatory drug) 100 mg, or methadone (an opiate) 10 mg 60 to 90 min prior to surgery, and their pain scores and postoperative medication requirements were measured for 3 days. All patients received local anesthetic blocks and analgesic drugs during the perioperative period. There were no significant differences between the three groups in the pain scores and medication requirements during the period of study. It was concluded that preoperative use of nonsteroidal anti-inflammatory drugs and opiates may not offer a preemptive analgesic effect in patients who have had adequate analgesia during the surgery. Continued use of analgesic drugs during the postoperative period is perhaps more useful for this purpose. There appears to be a higher incidence of vomiting following opiates (methadone), precluding its clinical use in day-care patients. PMID:10323113

Acute post-operative rhinosinusitis following endonasal dacryocystorhinostomy  

PubMed Central

Purpose To investigate the incidence and risk factors for acute rhinosinusitis (ARS) following endoscopic dacryocystorhinostomy (EnDCR). Methods Retrospective single-surgeon interventional case series, including 196 consecutive patients undergoing 203 endonasal DCR, with clinical and radiological evidence of nasolacrimal duct or common canalicular obstruction. Pre-operative lacrimal and sinonasal clinical assessment and imaging, intraoperative endoscopic video recording, and post-operative clinical and endoscopic findings were analysed for cases of ARS occurring within the first 4 weeks following DCR among patients with and without a past history of chronic rhinosinusitis (CRS). Surgical complications and outcomes at 12 months and management of ARS are reported. Results Three patients (1.5%) developed ARS within the first 5 post-operative days, none of which had experienced peri-operative complications and all had a past history of CRS. The rate of CRS in this cohort of 196 patients was 10.2% (n=20), of which 15% (n=3) developed ARS, although none had symptoms of CRS at the time of surgery; one had undergone previous sinus surgery. Presenting symptoms of ARS included facial pain, tenderness over the affected sinus, and nasal discharge; all patients responded to oral antibiotic therapy. Discussion The rate of ARS following EnDCR was 1.5%. In those with a prior history of CRS, it was 15% (P=0.009). ARS developed within the first post-operative week among patients with a past history of CRS, who were asymptomatic at the time of surgery, and responded to oral antibiotics. CRS may be a risk factor for the development of post-operative ARS. PMID:23846379

Current Evidence for Spinal Opioid Selection in Postoperative Pain  

PubMed Central

Background Spinal opioid administration is an excellent option to separate the desirable analgesic effects of opioids from their expected dose-limiting side effects to improve postoperative analgesia. Therefore, physicians must better identify either specific opioids or adequate doses and routes of administration that result in a mainly spinal site of action rather than a cerebral analgesic one. Methods The purpose of this topical review is to describe current available clinical evidence to determine what opioids reach high enough concentrations to produce spinally selective analgesia when given by epidural or intrathecal routes and also to make recommendations regarding their rational and safety use for the best management of postoperative pain. To this end, a search of Medline/Embase was conducted to identify all articles published up to December 2013 on this topic. Results Recent advances in spinal opioid bioavailability, based on both animals and humans trials support the theory that spinal opioid bioavailability is inversely proportional to the drug lipid solubility, which is higher in hydrophilic opioids like morphine, diamorphine and hydromorphone than lipophilic ones like alfentanil, fentanyl and sufentanil. Conclusions Results obtained from meta-analyses of RTCs is considered to be the 'highest' level and support their use. However, it's a fact that meta-analyses based on studies about treatment of postoperative pain should explore clinical surgery heterogeneity to improve patient's outcome. This observation forces physicians to use of a specific procedure surgical-based practical guideline. A vigilance protocol is also needed to achieve a good postoperative analgesia in terms of efficacy and security. PMID:25031805

Postoperative radiotherapy in salivary ductal carcinoma: a single institution experience  

PubMed Central

Purpose We reviewed treatment outcomes and prognostic factors for patients with salivary ductal carcinoma (SDC) treated with surgery and postoperative radiotherapy from 2005 to 2012. Materials and Methods A total of 16 patients were identified and 15 eligible patients were included in analysis. Median age was 61 years (range, 40 to 71 years) and 12 patients (80%) were men. Twelve patients (80%) had a tumor in the parotid gland, 9 (60%) had T3 or T4 disease, and 9 (60%) had positive nodal disease. All patients underwent surgery and postoperative radiotherapy. Postoperative radiotherapy was delivered using 3-dimensional conformal radiotherapy or intensity-modulated radiotherapy. Locoregional failure-free survival (LRFFS), distant failure-free survival (DFFS), progression-free survival (PFS), and overall survival (OS) were calculated using the Kaplan-Meier method. Differences in survival based on risk factors were tested using a log-rank test. Results Median total radiotherapy dose was 60 Gy (range, 52.5 to 63.6 Gy). Four patients received concurrent weekly chemotherapy with cisplatin. Among 10 patients who underwent surgery with neck dissection, 7 received modified radical neck dissection. With a median follow-up time of 38 months (range, 24 to 105 months), 4-year rates were 86% for LRFFS, 51% for DFFS, 46% for PFS, and 93% for OS. Local failure was observed in 2 patients (13%), and distant failure was observed in 7 (47%). The lung was the most common involved site of distant metastasis. Conclusion Surgery and postoperative radiotherapy in SDC patients resulted in good local control, but high distant metastasis remained a major challenge. PMID:25324983

Use of Probiotics as Prophylaxis for Postoperative Infections  

PubMed Central

Postoperative bacterial infections are common despite prophylactic administration of antibiotics. The wide-spread use of antibiotics in patients has contributed to the emergence of multiresistant bacteria. A restricted use of antibiotics must be followed in most clinical situations. In surgical patients there are several reasons for an altered microbial flora in the gut in combination with an altered barrier function leading to an enhanced inflammatory response to surgery. Several experimental and clinical studies have shown that probiotics (mainly lactobacilli) may reduce the number of potentially pathogenia bacteria (PPM) and restore a deranged barrier function. It is therefore of interest to test if these abilities of probiotics can be utilized in preoperative prophylaxis. These factors may be corrected by perioperative administration of probiotics in addition to antibiotics. Fourteen randomized clinical trials have been presented in which the effect of such regimens has been tested. It seems that in patients undergoing liver transplantation or elective surgery in the upper gastrointestinal tract prophylactic administration of different probiotic strains in combination with different fibers results in a three-fold reduction in postoperative infections. In parallel there seems to be a reduction in postoperative inflammation, although that has not been studied in a systematic way. The use of similar concepts in colorectal surgery has not been successful in reducing postoperative infections. Reasons for this difference are not obvious. It may be that higher doses of probiotics with longer duration are needed to influence microbiota in the lower gastrointestinal tract or that immune function in colorectal patients may not be as important as in transplantation or surgery in the upper gastrointestinal tract. The favorable results for the use of prophylactic probiotics in some settings warrant further controlled studies to elucidate potential mechanisms, impact on gut microbiota and influence on clinical management. The use of probiotics must be better delineated in relation to type of bacteria, dose and length of administration. PMID:22254113

Pilonidal sinus surgery: could we predict postoperative complications?  

PubMed

Pilonidal sinus surgery could, as of now, be considered a surgery tailored more to the surgeon than to the patient. In an attempt to give to surgeons an objective instrument of decision, we have evaluated which variables could be considered predictive of postoperative complications after pilonidal sinus surgery. A prospective electronic database of all patients treated for sacrococcygeal pilonidal disease was analysed. Sex, age, obesity, smoking, recurrent disease, the presence of multiple orifices and the distance between the most lateral orifice and midline were recorded and correlated with the occurrence of postoperative complications (infection and recurrence); 1006 patients were evaluated. Excision with primary mid-line closure was performed on all the patients. Mean follow-up was 7·3?±?3·6?years. A total of 158 patients with postoperative complications (infection and/or recurrence) were recorded during this period. A multivariate analysis showed that, after adjusting for major clinical and demographic characteristics, only a recurrent disease [odds ratio (OR): 3·41, 95% confidence interval (CI): 1·89-6·15, P?postoperative complications. Focussing on the distance from midline, the receiver operative characteristic (ROC) analysis showed that the distance of lateral orifice from midline predicted 79·2% of complications and the Youden's test identified the best cut-off as 2·0?cm for this variable. An evidence-based tool for deciding on the type of surgical intervention could be developed and validated by further ad hoc prospective studies evaluating our results in comparison to other different types of surgical techniques. Our results support the use of these variables as an effective way to tailor pilonidal sinus surgery to the patient, so as to obtain the best results in patient care. PMID:24894163

Bei Annäherung der bespülten Wand an die Düse kommt es zu qualitativen Änderungen des Stromfeldes. Diese Änderungen sind aus dem Verlauf des Wanddruckes sowie des Stoffübergangskoeffizienten zu sehen. Es wurden zwei verschiedene Arten dieser Verläufe beobachtet, denen zwei verschiedene Zustände des Stromfeldes entsprechen. Die Änderung von einem zu anderem ist sehr plötzlich und hat einen hysteresen charakter The paper is an experimental study of a special kind of slot nozzle. The flow field with recirculation area results from a structure built in the nozzle (the so called combined slot nozzle). As the nozzle to wall distance changes, quantitative changes of the flow field occur. They can be seen in the development of the wall pressure as well as in the development of the mass transfer coefficient. Two different sorts of this development have been observed, corresponding to two different states of the flow field. The change of one into the other is very rapid and hysteretic in character.

[Prediction of postoperative pain - beneficial to perioperative pain management?].  

PubMed

Pain treatment of surgical patients is still a deficient area, even if there are evidence-based possibilities of pain management. The aim of this study is to identify patients with a higher risk of severe postoperative pain at an early stage and improve nurses' pain management by identifying pain predictors whilst including them in analgesic treatment. In addition to the identification of predictors by a literature review, a cross-sectional study with 84 surgical patients of a convenience sample was undertaken to find possible predictors. The enquiry was conducted by means of a questionnaire which the patient had to fill in prior surgery. The intensity of pain was surveyed in a personal interview on the first post-operative day. Correlation analysis was applied to verify the statistical significance of patient characteristics as well as surgical variables. Out of the 14 variables preoperative pain was found to increase the risk of postoperative pain. Comparison with other studies showed inconsistent results for pain predictors, and therefore nursing pain management based on pain predictors seems questionable. PMID:21480176

Detection of Postoperative Intestinal Ischemia in Small Bowel Transplants  

PubMed Central

Small bowel transplantation is acknowledged as auto- and allotransplantation. In both instances, there is up to a 4%–10% risk of postoperative ischemia, and as the small bowel is extremely susceptible to ischemia, the timely diagnosis of ischemia is important. The location of the transplant, whether it is buried in the abdominal cavity or in the neck region, increases the challenge, as monitoring becomes more difficult and the consequences of neglect more dangerous. All methods for the early detection of postoperative ischemia in small bowel transplants are described together with the requirements of the ideal monitoring method. A small bowel transplant can be inspected directly or indirectly; the blood flow can be monitored by Doppler or by photoplethysmography, and the consequences of the blood flow can be monitored. The ideal monitoring method should be reliable, fast, minimally invasive, safe, objective, easy, cheap, and comfortable. No monitoring methods today fulfill the criteria of the ideal monitoring method, and evidence-based guidelines regarding postoperative monitoring cannot be made. The choice of whether to implement monitoring of ischemia—and if so, which method to choose—has to be made by the individual surgeon or center. PMID:23209878

Postoperative pain management in patients with chronic kidney disease  

PubMed Central

Chronic kidney disease (CKD) is a health care problem with increasing prevalence worldwide. Pain management represents one of the challenges in providing perioperative care for this group of patients. Physicians from different specialties may be involved in pain management of CKD patients, especially in advanced stages. It is important to understand the clinical staging of kidney function in CKD patients as the pharmacotherapeutic pain management strategies change as kidney function becomes progressively impaired. Special emphasis should be placed on dose adjustment of certain analgesics as well as prevention of further deterioration of renal function that could be induced by certain classes of analgesics. Chronic pain is a common finding in CKD patients which may be caused by the primary disease that led to kidney damage or can be a direct result of CKD and hemodialysis. The presence of chronic pain in some of the CKD patients makes postoperative pain management in these patients more challenging. This review focuses on the plans and challenges of postoperative pain management for patient at different stages of CKD undergoing surgical intervention to provide optimum pain control for this patient population. Further clinical studies are required to address the optimal medication regimen for postoperative pain management in the different stages of CKD. PMID:25788766

Efficacy of Postoperative Prophylactic Antibiotic Therapy in Third Molar Surgery  

PubMed Central

Introduction: Surgical extraction of mandibular third molar is the most frequently performed procedure in oral surgery. This procedure is associated with significant postoperative sequelae such as trismus, swelling, pain and infection. The need of antibiotic therapy during the removal of mandibular third molar has been a contentious issue. Method: This study investigated a regimen by using amoxycillin and metronidazole in one group and without using antibiotics in the other. Both the groups were assessed postoperatively on the 1st, 2nd, 5th, 7th and 10th days by the same observer for post operative mouth opening (interincisal distance), presence of a purulent discharge at the site of surgery, pain and swelling. Result: Overall, no statistically significant difference was seen between both the treatment groups when interincisal distance, pain, swelling and purulent discharge were considered. Conclusion: The results of this study failed to show any advantage which was associated with the routine postoperative use of antibiotics in asymptomatic third molar surgeries. PMID:24995236

[Postoperative behavior syndrome in dental practice in children].  

PubMed

The literature contains numerous publications on the issue of Postoperative Behavior. The purpose of this study was to obtain installment of the objective data on the occurrence of Postoperative Behavior in dental profile patients depending on various factors. Age of the children who underwent the study ranged from 3 to 5 years. The study group included 531 patients, while the control group contained 103 children who were treated independently. During the hospital admission patient's parents were asked to fill in the appropriate grading systems, such as MAS, DAS, STAI, mYPAS and PHBQ, the general information table was filled in as well, which, in addition to general demographic characteristics, considered factors such as: age, number of unsuccessful attempts to sanate the oral cavity, the number of caries, etc. The most important factors that are strongly correlated with the development of PHBQ, were statistically considered as r < 0.1 and p > 0.005. Number of the unsuccessful attempts to cure the child by a dentist forms a phobic syndrome of dental treatments, manifestation of which are different psychosomatic disorders inherent to Postoperative Behavior.

[Effect of premedication on the formation of postoperative pain syndrome].  

PubMed

The pronouncement degree and dynamics of pain syndrome were assessed after surgeries in the abdominal cavity organs with regard for a nature of the analgetic component of premedication and of the postoperative analgesic therapy (n = 155). The administration of analgesics before extra-traumatic surgeries was found to be compulsory in order to prevent the onset of a persistent postoperative pain syndrome. A combination of non-steroid anti-inflammatory drugs, i.e. ketonal, and of a high-efficiency agonist of opiate mu-receptors, i.e. bupranal, was acknowledged as most effective in coping with this task. It was demonstrated that the application of "the forestalling analgesia" by ketonal (100 mg in 30 min before the beginning of moderate- and mild-trauma surgical interventions and immediately after the finalization of such surgeries) contributed to an essentially lower pronouncement degree of the postoperative pain syndrome and made the administration of narcotic analgesics unnecessary. Finally, it is pointed out that promedol could not be regarded as a drug ensuring a safe prophylaxis of the central sensitization and hyperalgesia. PMID:14524007

Postoperative management of dogs with gastric dilatation and volvulus.  

PubMed

The objective of the study was to review the veterinary literature for evidence-based and common clinical practice supporting the postoperative management of dogs with gastric dilatation and volvulus (GDV). GDV involves rapid accumulation of gas in the stomach, gastric volvulus, increased intragastric pressure, and decreased venous return. GDV is characterized by relative hypovolemic-distributive and cardiogenic shock, during which the whole body may be subjected to inadequate tissue perfusion and ischemia. Intensive postoperative management of the patients with GDV is essential for survival. Therapy in the postoperative period is focused on maintaining tissue perfusion along with intensive monitoring for prevention and early identification of ischemia-reperfusion injury (IRI) and consequent potential complications such as hypotension, cardiac arrhythmias, acute kidney injury (AKI), gastric ulceration, electrolyte imbalances, and pain. In addition, early identification of patients in need for re-exploration owing to gastric necrosis, abdominal sepsis, or splenic thrombosis is crucial. Therapy with intravenous lidocaine may play a central role in combating IRI and cardiac arrhythmias. The most serious complications of GDV are associated with IRI and consequent systemic inflammatory response syndrome and multiple organ dysfunction syndrome. Other reported complications include hypotension, AKI, disseminated intravascular coagulation, gastric ulceration, and cardiac arrhythmias. Despite appropriate medical and surgical treatment, the reported mortality rate in dogs with GDV is high (10%-28%). Dogs with GDV that are affected with gastric necrosis or develop AKI have higher mortality rates. PMID:25496926

Haptische Simulationsmodelle dienen in der Medizin in erster Linie dem Training operativer Eingriffe. Sie basieren zumeist auf physikalischen Gewebemodellen, welche eine sehr genaue Simulation der biomechanischen Eigenschaften des betreffenden Gewebes erlauben, aber gleichzeitig sehr rechenintensiv und damit zeitaufwändig in der Ausführung sind. Die menschliche Wahrnehmung kann allerdings auch eine ungenaue haptische Modellierung psychooptisch ausgleichen. Daher kann es sinnvoll sein, haptische Simulationen auch mit nicht vollständig physikalisch definierten Deformationsmodellen durchzuführen. Am Beispiel der haptischer Simulation einer in-vitro Fertilisation wird gezeigt, dass durch die Anwendung eines geometrischen Deformationsmodells eine künstliche Befruchtung unter realistischen experimentellen Bedingungen in Echtzeit haptisch simuliert und damit trainiert werden kann.

Single dose oral nefopam for acute postoperative pain in adults  

PubMed Central

Background Nefopam is a centrally-acting but non-opioid analgesic drug of the benzoxazocine chemical class, developed in the early 1970s. It is widely used, mainly in European countries, for the relief of moderate to severe pain as an alternative to opioid analgesic drugs, and used in rheumatic disease and other musculoskeletal disorders in the UK. This review sought to evaluate the efficacy and safety of oral nefopam in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties. Objectives To assess the efficacy of single dose oral nefopam in acute postoperative pain, and any associated adverse events. Search methods We searched CENTRAL (Issue 2, 2009), MEDLINE (1966 to May 2009); EMBASE via Ovid (1980 to May 2009); the Oxford Pain Relief Database (1950 to 1994); and reference lists of studies found. Selection criteria Randomised, double-blind, placebo-controlled clinical trials of oral nefopam for relief of acute postoperative pain in adults. Data collection and analysis Two review authors independently assessed trial quality and extracted data. The area under the “pain relief versus time” curve was used to derive the proportion of participants with nefopam and placebo experiencing least 50% pain relief over 4 to 6 hours, using validated equations. The number-needed-to-treat-to-benefit (NNT) was calculated using 95% confidence intervals (CIs). The proportion of participants using rescue analgesia over a specified time period, and time to use of rescue analgesia, were sought as additional measures of efficacy. Information on adverse events and withdrawals was also collected. Main results No included studies were identified after examining in detail thirteen studies on oral nefopam in participants with established postoperative pain. Authors’ conclusions In the absence of evidence of efficacy for oral nefopam in acute postoperative pain, its use in this indication is not justified. Because trials clearly demonstrating analgesic efficacy in the most basic of acute pain studies are lacking, use in other indications should be evaluated carefully. Given the large number of available drugs of this and similar classes, there is no urgent research agenda. PMID:19588431

A Comparative Clinical Evaluation of the Effect of Preoperative and Postoperative Antimicrobial Therapy on Postoperative Sequelae after Impacted Mandibular Third Molar Extraction  

PubMed Central

ABSTRACT Objectives To compare the effect of preoperative and postoperative antibiotics therapy on postoperative sequelae after impacted mandibular third molar extractions. Material and Methods This was a prospective study conducted at Department of Oral and Maxillofacial Surgery of the Lagos University Teaching Hospitalon consecutive patients with impacted third molar extractions for a 12 month period. Group I (n = 31) had administration of 1 gram of oral metronidazole and 1 gram of amoxicillin capsules 30 minutes preoperative and Group II (n = 31) had 500 milligrams of amoxicillin capsule 8 hourly and 400 milligrams of metronidazole tablets administered post operatively for 5 days. Pain, facial swelling and mouth opening assessment were done postoperatively and on days 1, 3 and 7. Results The general pattern of postoperative pain, regardless of antimicrobial use revealed that pain increased from day 1 to day 3 postoperatively and began to decrease in intensity subsequently up to the seventh day. There was however a statistically significant difference (P = 0.0001) between the two groups on the 7th postoperative day with the subjects in Group I showing lower pain intensity. The mean difference of the facial width on days 1 and 3 was significant (P = 0.04 and P = 0.0001 respectively) with subjects in Group II having a reduced facial width compared to those in Group I. Conclusions This study suggested that the administration of preoperative or postoperative antibiotics showed no marked differences in the degree of postoperative sequaele that occur after impacted mandibular third molar extractions.

Postoperative outcomes following pancreaticoduodenectomy: how should age affect clinical practice?  

PubMed Central

Background Pancreaticoduodenectomy is an increasingly common procedure performed for both benign and malignant disease. There are conflicting data regarding the safety of pancreatic resection in older patients. Potentially modifiable perioperative risk factors to improve outcomes in older patients have yet to be determined. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database for 2008 to 2009 was used for this retrospective analysis. Patients undergoing pancreaticoduodenectomy were identified and divided into those above and below the age of 65. Preoperative risk factors and postoperative morbidity and mortality were evaluated. Results Among 2,045 patients included in this analysis, 994 patients were >65 years (48.6%) while 1,051 were (less than or equal to) 65 years (51.4%). Thirty-day mortality was higher in the older age group compared to the younger age group 3.6% vs. 1.9% respectively, P = 0.017, odds ratio 1.94. Older patients had a higher incidence of unplanned intubation, ventilator support >48 h and septic shock compared with younger patients. On multivariate logistic regression, after adjusting for other 30-day postoperative occurrences (significant at the P <0.1 level) only septic shock was independently associated with a higher odds of mortality, unplanned intubation, and ventilator support >48 h in older patients compared with younger patients. Conclusions This report from a population-based database is the first to highlight postoperative sepsis as an independent risk factor for mortality and morbidity in older patients undergoing pancreatic resection. Careful perioperative management addressing this issue is essential for patients over the age of 65. PMID:23742036

Epileptogenic temporal cavernous malformations: operative strategies and postoperative seizure outcomes.  

PubMed

Operative treatment of epileptogenic cavernous malformations (CM) continues under debate. Most studies focus on surgery for supratentorial CM in general. For temporal lobe CM, surgical decision-making concerns in particular whether to perform lesionectomy alone or the additional excision of mesial temporal structures. The purpose of this case series was to evaluate operative strategies used to treat epileptogenic temporal CM and to report resultant postoperative seizure outcomes. Twelve consecutive cases of patients with medically intractable epilepsy who underwent operation for temporal CM between 1996 and 2006 were retrospectively reviewed. When the temporal CM directly invaded the hippocampus or amygdala, the affected structures were resected in addition to the lesion; when the CM was located in the superficial temporal cortex, and there was no radiographic evidence of hippocampal sclerosis, lesionectomy alone was done; with CM located between the superficial temporal cortex and the mesial temporal region, other factors were considered in decision-making, such as lesion proximity to the deep mesiotemporal structures and preoperative epilepsy duration. For six of the twelve patients, extended lesionectomy (EL) alone was done; for the other six, tailored anteromedial temporal resection with hippocampectomy and/or amygdalectomy was performed in addition to EL. Postoperatively, 11 patients - all with preoperative VEM demonstrating electroclinical seizure patterns concordant with lesion location - were seizure-free. We conclude that epileptogenic temporal CM are surgically remediable, when approached with the above operative strategies and presurgical VEM. On the basis of these postoperative seizure control results, we recommend consideration of concurrent resection of mesial temporal structures with EL for certain temporal CM. PMID:20045354

A ventilation strategy during general anaesthesia to reduce postoperative atelectasis  

PubMed Central

Background Atelectasis is common during and after general anaesthesia. We hypothesized that a ventilation strategy, without recruitment manoeuvres, using a combination of continuous positive airway pressure (CPAP) or positive end-expiratory pressure (PEEP) and a reduced end-expiratory oxygen fraction (FETO2) before ending mask ventilation with CPAP after extubation would reduce the area of postoperative atelectasis. Methods Thirty patients were randomized into three groups. During induction and emergence, inspiratory oxygen fractions (FIO2) were 1.0 in the control group and 1.0 or 0.8 in the intervention groups. No CPAP/PEEP was used in the control group, whereas CPAP/PEEP of 6 cmH2O was used in the intervention groups. After extubation, FIO2 was set to 0.30 in the intervention groups and CPAP was applied, aiming at FETO2 < 0.30. Atelectasis was studied by computed tomography 25 min postoperatively. Results The median area of atelectasis was 5.2 cm2 (range 1.6–12.2 cm2) and 8.5 cm2 (3–23.1 cm2) in the groups given FIO2 1.0 with or without CPAP/PEEP, respectively. After correction for body mass index the difference between medians (2.9 cm2) was statistically significant (confidence interval 0.2–7.6 cm2, p = 0.04). In the group given FIO2 0.8, in which seven patients were ex- or current smokers, the median area of atelectasis was 8.2 cm2 (1.8–14.7 cm2). Conclusion Compared with conventional ventilation, after correction for obesity, this ventilation strategy reduced the area of postoperative atelectasis in one of the intervention groups but not in the other group, which included a higher proportion of smokers.

Transperineal Management for Postoperative and Radiation Rectourethral Fistulas  

PubMed Central

Purpose The rectal sphincter preserving transperineal approach has been increasingly used successfully. We analyzed our experience with this surgical approach. A secondary aim was to evaluate the surgical outcome of energy ablative rectourethral fistulas without a concomitant interposition muscle flap. Materials and Methods We identified all patients with rectourethral fistula who underwent rectal sphincter preserving transperineal repair from 1998 to 2011. Re-approximation of the urethral mucosa, posterior anastomotic urethroplasty or partial/total prostatectomy with urethrovesical anastomosis was performed for urinary closure. The fistula cohort was divided into 2 groups, including postoperative and energy ablative fistulas, respectively. Success after perineal rectourethral fistula repair was defined as resolution after the first attempt at repair. Results A total of 23 patients underwent rectal sphincter preserving, transperineal rectourethral fistula repair. In the postoperative fistula cohort the fistula was successfully resolved in all 10 patients. A dartos interposition muscle flap was used in 2 of 10 patients. In the energy ablative cohort the fistula was successfully closed in 8 of 13 patients. An interposition muscle flap was not placed in 8 patients with an energy ablative fistula, of whom success was achieved in 5. Two of the 5 patients with an energy ablative fistula and a successful outcome without a concomitant interposition muscle flap had urinary extravasation, necessitating temporary catheterization. Conclusions Rectal sphincter preserving transperineal repair is a successful surgical method to repair postoperative and energy ablative rectourethral fistulas. An interposition muscle flap should be considered in the setting of energy ablative rectourethral fistulas to increase successful outcomes. PMID:23009867

Single dose oral flurbiprofen for acute postoperative pain in adults  

PubMed Central

Background Flurbiprofen is a non-selective non-steroidal anti-inflammatory drug (NSAID), related to ibuprofen and naproxen, used to treat acute and chronic painful conditions. There is no systematic review of its use in acute postoperative pain. Objectives To assess efficacy, duration of action, and associated adverse events of single dose oral flurbiprofen in acute postoperative pain in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to January 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered flurbiprofen in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk (RR) and number needed to treat to benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. Main results Eleven studies compared flurbiprofen (699 participants) with placebo (362 participants) in studies lasting 6 to 12 hours. Studies were of adequate reporting quality, and most participants had pain following dental extractions. The dose of flurbiprofen used was 25 mg to 100 mg, with most information for 50 mg and 100 mg. The NNT for at least 50% pain relief over 4 to 6 hours for flurbiprofen 50 mg compared with placebo (692 participants) was 2.7 (2.3 to 3.3) and for 100 mg (416 participants) it was 2.5 (2.0 to 3.1). With flurbiprofen 50 mg and 100 mg 65% to 70% of participants experienced at least 50% pain relief, compared with 25% to 30% with placebo. Rescue medication was used by 25% and 16% of participants with flurbiprofen 50 mg and 100 mg over 6 hours, compared with almost 70% with placebo. Adverse events were uncommon, and not significantly different from placebo. Authors’ conclusions Flurbiprofen at doses of 50 mg and 100 mg is an effective analgesic in moderate to severe acute postoperative pain. The NNT for at least 50% pain relief is similar to that of commonly used NSAIDs such as ibuprofen and naproxen at usual doses. Use of rescue medication indicates a duration of action exceeding 6 hours. PMID:19588427

Single dose oral ibuprofen for acute postoperative pain in adults  

PubMed Central

Background This review updates a 1999 Cochrane review showing that ibuprofen at various doses was effective in postoperative pain in single dose studies designed to demonstrate analgesic efficacy. New studies have since been published. Ibuprofen is one of the most widely used non-steroidal anti-inflammatory (NSAID) analgesics both by prescription and as an over-the-counter medicine. Ibuprofen is used for acute and chronic painful conditions. Objectives To assess analgesic efficacy of ibuprofen in single oral doses for moderate and severe postoperative pain in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to May 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered ibuprofen (any formulation) in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk and number-needed-to-treat-to-benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. Main results Seventy-two studies compared ibuprofen and placebo (9186 participants). Studies were predominantly of high reporting quality, and the bulk of the information concerned ibuprofen 200 mg and 400 mg. For at least 50% pain relief compared with placebo the NNT for ibuprofen 200 mg (2690 participants) was 2.7 (2.5 to 3.0) and for ibuprofen 400 mg (6475 participants) it was 2.5 (2.4 to 2.6). The proportion with at least 50% pain relief was 46% with 200 mg and 54% with 400 mg. Remedication within 6 hours was less frequent with higher doses, with 48% remedicating with 200 mg and 42% with 400 mg. The median time to remedication was 4.7 hours with 200 mg and 5.4 hours with 400 mg. Sensitivity analysis indicated that pain model and ibuprofen formulation may both affect the result, with dental impaction models and soluble ibuprofen salts producing better efficacy estimates. Adverse events were uncommon, and not different from placebo. Authors’ conclusions The very substantial amount of high quality evidence demonstrates that ibuprofen is an effective analgesic in treating postoperative pain. NNTs for 200 mg and 400 mg ibuprofen did not change significantly from the previous review even when a substantial amount of new information was added. New information is provided on remedication.

Management strategies to reduce risk of postoperative infections  

PubMed Central

Postoperative infections, although rare, are still of great concern to the ophthalmologist. The incidence of post-cataract endophthalmitis is low, with a range of .28 per 1,000 to 2.99 per 1000. In addition to intraoperative considerations such as poor wound construction, vitreous loss, topical anesthesia, and prolonged surgical time, other risk factors include preoperative factors such as a diseased ocular surface and systemic immunosuppression. Potential methods of reducing risk of endophthalmitis after anterior segment surgery are discussed and available literature is summarized. PMID:24319649

Approach to postoperative fever in pediatric cardiac patients  

PubMed Central

Fever in the postoperative period in children undergoing surgery for congenital heart disease is fairly common and tends to cause anxiety to both the surgeon and the patient. Such fever is associated with the metabolic response to trauma, systemic response to the cardiopulmonary bypass, hypothermia, presence of drainage tubes, drugs, blood transfusion as well as infections. Establishing the diagnosis requires proper assessment of the patient with focused history, targeted physical examination and judicious use of investigations with the knowledge of the common causes.

Incidence of stroke and acute renal failure in patients of postoperative atrial fibrillation after myocardial revascularization  

PubMed Central

Introduction Postoperative atrial fibrillation is the most common arrhythmia in cardiac surgery, its incidence range between 20% and 40%. Objective Quantify the occurrence of stroke and acute renal insufficiency after myocardial revascularization surgery in patients who had atrial fibrillation postoperatively. Methods Cohort longitudinal bidirectional study, performed at Portuguese Beneficent Hospital (SP), with medical chart survey of patients undergoing myocardial revascularization surgery between June 2009 to July 2010. From a total of 3010 patients were weaned 382 patients that presented atrial fibrillation preoperatively and/or associated surgeries. The study was conducted in accordance with national and international following resolutions: ICH Harmonized Tripartite Guidelines for Good Clinical Practice - 1996; CNS196/96 Resolution, and Declaration of Helsinki. Results The 2628 patients included in this study were divided into two groups: Group I, who didn't show postoperative atrial fibrillation, with 2302 (87.6%) patients; and group II, with 326 (12.4%) who developed postoperative atrial fibrillation. The incidence of stroke in patients was 1.1% without postoperative atrial fibrillation vs. 4% with postoperative atrial fibrillation (P<0.001). Postoperative acute renal failure was observed in 12% of patients with postoperative atrial fibrillation and 2.4% in the group without postoperative atrial fibrillation (P<0.001), that is a relation 5 times greater. Conclusion In this study there was a high incidence of stroke and acute renal failure in patients with postoperative atrial fibrillation, with rates higher than those reported in the literature.

Schönheit und andere Provokationen - Eine neue evolutionsbiologische Theorie der Kunst  

NASA Astrophysics Data System (ADS)

Die Evolution hat viele spektakuläre Phänomene hervorgebracht - von der Eleganz des Vogelflugs über die gigantischen Körper der Dinosaurier und die farbenprächtige Vielfalt der Korallenriffe bis hin zu ihrem jüngsten Geniestreich - der menschlichen Kunst. Die schönen Künste - Malerei, Bildhauerei und Architektur, Theater, Tanz, Oper und Filmkunst, Musik und Literatur - Produkte der Evolution? Diese Vorstellung mutet vielen Menschen fremd an, aber wie könnte es anders sein? Denn wenn Charles Darwin recht hat, dann sind nicht nur die körperlichen Merkmale der Menschen als Antworten auf die Erfordernisse des Lebens entstanden, sondern auch ihre geistigen Fähigkeiten und Verhaltensweisen. Im Jahr 1859 hatte er auf den letzten Seiten seines berühmten Buches über die Entstehung der Arten eine kühne Prophezeiung gemacht: Durch die Evolutionstheorie werde es "zu einer bemerkenswerten Revolution in der Naturwissenschaft kommen […]. Die Psychologie wird auf die neue Grundlage gestellt, dass jede geistige Kraft und Fähigkeit notwendigerweise durch graduelle Übergänge erworben wird“ (Darwin 1859, S. 484, 488; Junker 2008).

The importance of communication in the management of postoperative pain.  

PubMed

This study investigates the importance of communication in surgery and how delivering preoperative patient education can lead to better health outcomes postoperatively, via promoting tolerable pain scores and minimizing the use of narcotics after surgery. Patients who underwent outpatient surgery were randomly divided into groups to compare the pain scores of those who received preoperative patient education, the experimental group, and those who did not receive any form of patient education, the control group. Two weeks before surgery, the experimental group subjects received oral and written forms of patient education consisting of how the body responds to pain, and how endorphins cause natural analgesia. Moreover, patients were educated on the negative effects narcotics have on endorphin production and activity, as well as mechanisms of non-opioid analgesics. Of the 69 patients in the experimental group, 90% declined a prescription for hydrocodone after receiving preoperative education two weeks prior to surgery. The control group consisted of 66 patients who did not receive preoperative patient education and 100% filled their hydrocodone prescriptions. Patients in both groups were offered and received gabapentin and celecoxib preoperatively for prophylaxis of postoperative pain unless they declined. The control groups were found to have average pain scores significantly greater (P <.05) than the experimental groups and also a significantly longer (P <.005) duration of pain. This study illustrates the power of patient education via oral, written and visual communication, which can serve as an effective means to minimize narcotic analgesia after surgery. PMID:23795326

Necrotizing fasciitis: microbiological characteristics and predictors of postoperative outcome  

PubMed Central

Objective Necrotizing fasciitis is a life threatening soft-tissue infection with a high morbidity and mortality. Prompt treatment based on extensive surgical debridement and antibiotic therapies are the therapeutic principles. Methods The medical records of patients with necrotizing fasciitis (n = 26) from 1996 to 2005 were retrospectively analyzed. Results The localization of necrotizing fasciitis was most commonly the trunk (42.3%). Type I polymicrobial infection was the dominating infection. The involvement of anaerobic bacteria was associated with an increase in the number of surgical revisions (p = 0.005). Length of postoperative intensive care unit stay, duration of postoperative ventilation and mortality were significantly increased in the ASA IV-V group. Computed tomography displayed only a limited significance as diagnostic tool for initial diagnosis. Conclusions In severe cases the combination of necrotic skin and soft tissue gas facilitates the correct diagnosis, which should than be followed by immediate - and most often - repeated debridement. If anaerobes are isolated an early and aggressive second look is necessary. PMID:19258208

Influence of postoperative enteral nutrition on postsurgical infections.  

PubMed Central

BACKGROUND: This study was undertaken to test the hypothesis that early enteral nutrition might reduce the incidence of serious complications after major abdominal surgery. METHODS: In a randomised double blind prospective trial 30 patients received Nutri-drink and 30 patients received placebo through a nasoduodenal feeding tube. On the day of operation the patients were given median 600 ml of either nutrition or placebo, 60 ml per hour. On the first postoperative day the patients received either 1000 ml (median) of nutrition or placebo, on day 2 1200 ml (median) nutrition, 1400 ml placebo, on day 3 1000 ml (median) nutrition, 1150 ml placebo, and on day 4 1000 ml (median) nutrition, 800 ml placebo. All patients were followed up for 30 days by the same investigator. RESULTS: The two groups were similar with regard to nutritional status and type of operation. The rate of postoperative infectious complications was significantly lower in the nutrition group, two of 30 compared with 14 of 30 in the placebo group (p = 0.0009). CONCLUSION: Early enteral nutrition given to patients after major abdominal surgery results in an important reduction in infectious complications. PMID:9038665

Gastric Decompression Decreases Postoperative Nausea and Vomiting in ENT Surgery  

PubMed Central

There is a passive blood flow to the stomach during oral and nasal surgery. It may cause postoperative nausea and vomiting (PONV). We researched the relationship between gastric decompression (GD) and severity of PONV in ear, nose, and throat (ENT) surgery. 137 patients who have been into ENT surgery were included in the study. In Group I (n = 70), patients received GD after surgery before extubation; patients in Group II (n = 67) did not receive GD. In postoperative 2nd, 4th, 8th, and 12th hours, the number and ratio of patients demonstrating PONV were detected to be significantly more in Group II as compared to Group I. PONV was also significantly more severe in Group II as compared to Group I. In Group I, the PONV ratio in the 2nd hour was significantly more for those whose amounts of stomach content aspired were more than 10?mL as compared to those whose stomach content aspired was less than 10?mL. In the 4th, 8th, and 24th hours, there is no statistically significant difference between the stomach content aspired and PONV ratio. GD reduces the incidence and severity of PONV in ENT surgery.

Effect of Pregabalin and Dexamethasone on Postoperative Analgesia after Septoplasty  

PubMed Central

Objectives. The aim of this study was to explore effect of a combination of pregabalin and dexamethasone on pain control after septoplasty operations. Methods. In this study, 90 patients who were scheduled for septoplasty under general anesthesia were randomly assigned into groups that received either placebo (Group C), pregabalin (Group P), or pregabalin and dexamethasone (Group PD). Preoperatively, patients received either pregabalin 300?mg one hour before surgery, dexamethasone 8?mg intravenously during induction, or placebo according to their allocation. Postoperative pain treatment included tramadol and diclofenac sodium 30 minutes before the end of the operation. Numeric rating scale (NRS) for pain assessment, side effects, and consumption of tramadol, pethidine, and ondansetron were recorded. Results. The median NRS score at the postoperative 0 and the 2nd?h was significantly higher in Group C than in Group P and Group PD (P ? 0.004 for both). The 24?h tramadol and pethidine, consumptions were significantly reduced in Groups P and PD compared to Group C (P < 0.001 and P < 0.001). The incidence of blurred vision was significantly higher in Group PD compared to Group C within both 0–2?h and 0–24?h periods (P = 0.002 and P < 0.001, resp.). Conclusions. We conclude that administration of 300 mg pregabalin preoperatively may be an adequate choice for pain control after septoplasty. Addition of dexamethasone does not significantly reduce pain in these patients. PMID:24876957

Predictive factors for postoperative wound complications after neck dissection.  

PubMed

The objective of this retrospective study was to evaluate risk factors for wound complications after neck dissection. One hundred and nineteen patients were treated with neck dissection for squamous-cell carcinoma of the upper aerodigestive tract at the National Cancer Institute in Rome between 2006 and 2009. Postoperative wound complications were divided into major or minor and were related to different variables to identify risk factors. Postoperative wound complications were found in 20.2% of patients with an individual patient probability for different risk factors ranging from 2% to 34.1%. Preoperative chemoradiation therapy (CRT) and the type of neck dissection were associated with a higher risk of major complications (p ? 0.05). Previous CRT and radical neck dissection/modified radical neck dissection are risk factors for major wound complications in patients with head and neck squamous cell carcinoma undergoing neck dissection. Patients requiring neck dissection after CRT should be informed about the increased risk of the procedure, and selective neck dissection, if oncologically appropriate, should be considered to reduce complications.

Statins and Postoperative Infections: A Randomized Clinical Trial  

PubMed Central

Background: Observational studies, rather than randomized trials, revealed that statins might be associated with other benefits. Objectives: The present study aimed at evaluating the preventive effects of lovastatin when used as a prophylactic agent for early and late infective complications after surgery. Patients and Methods: A total of 149 patients undergoing elective intracranial and spinal surgeries, were enrolled in a double- blind randomized clinical trial in the department of neurosurgery of a teaching hospital. An amount of 20 mg lovastatin and the same dose of placebo, one day before the operation and three days after the surgery, were used for cases and controls, respectively. The patients were evaluated for local and systemic infections during hospitalization and 10, 30, 60 and 90 days after discharge. Results: A total of 149 patients, 78 men and 71 women with a mean age of 40.3 ± 16.5, were assigned to prophylactic protocols. 46 and 103 patients were in the case and control groups, respectively. Eight episodes of infection were detected, including six bacterial meningitis and two episodes of hospital- acquired pneumonia. All of the patients with documented postoperative infections were part of the placebo group, however, there were no significant statistical differences between the groups (P = 0.059). Conclusions: In spite of the differences between the two groups, the results did not significantly support the preventive effect of statins in postoperative infections. PMID:25147705

Postoperative Pulmonary Dysfunction and Mechanical Ventilation in Cardiac Surgery  

PubMed Central

Postoperative pulmonary dysfunction (PPD) is a frequent and significant complication after cardiac surgery. It contributes to morbidity and mortality and increases hospitalization stay and its associated costs. Its pathogenesis is not clear but it seems to be related to the development of a systemic inflammatory response with a subsequent pulmonary inflammation. Many factors have been described to contribute to this inflammatory response, including surgical procedure with sternotomy incision, effects of general anesthesia, topical cooling, and extracorporeal circulation (ECC) and mechanical ventilation (VM). Protective ventilation strategies can reduce the incidence of atelectasis (which still remains one of the principal causes of PDD) and pulmonary infections in surgical patients. In this way, the open lung approach (OLA), a protective ventilation strategy, has demonstrated attenuating the inflammatory response and improving gas exchange parameters and postoperative pulmonary functions with a better residual functional capacity (FRC) when compared with a conventional ventilatory strategy. Additionally, maintaining low frequency ventilation during ECC was shown to decrease the incidence of PDD after cardiac surgery, preserving lung function. PMID:25705516

Reverse Total Shoulder Replacement: Intraoperative and Early Postoperative Complications  

PubMed Central

Reverse total shoulder arthroplasty is a treatment option for patients with symptomatic glenohumeral arthritis and a deficient rotator cuff. The reported complication rates vary from 0% to 68%. Given this variation, our purposes were to (1) determine the learning curve for the procedure, (2) identify complications and surgical pitfalls, and (3) compare our results with those of similar published series. We retrospectively reviewed 20 consecutive patients (mean age, 73 years; range, 45–88 years) who had reverse total shoulder arthroplasty by one surgeon, tabulating intraoperative and postoperative complications. Minimum followup was 3 months (average, 9 months; range, 3–21 months). The intraoperative complication rate for the first 10 patients was higher than that for the second 10 patients. There were 33 complications in 15 patients: 11 patients collectively had 22 intraoperative complications and eight patients collectively had 11 postoperative complications. At radiographic followup, 11 patients had scapular notching and nine patients had heterotopic ossification. Our complication rate was higher than published rates. Level of Evidence: Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence. PMID:18685908

The effects of early postoperative radiation on vascularized bone grafts  

SciTech Connect

The effects of early postoperative radiation were assessed in free nonvascularized and free vascularized rib grafts in the canine model. The mandibles of one-half of the dogs were exposed to a cobalt 60 radiation dose of 4080 cGy over a 4-week period, starting 2 weeks postoperatively. The patency of vascularized grafts was confirmed with bone scintigraphy. Histological studies, including ultraviolet microscopy with trifluorochrome labeling, and histomorphometric analyses were performed. Osteocytes persist within the cortex of the vascularized nonradiated grafts to a much greater extent than in nonvascularized, nonradiated grafts. Cortical osteocytes do not persist in either vascularized or nonvascularized grafts subjected to radiation. New bone formation is significantly retarded in radiated grafts compared with nonradiated grafts. Periosteum and endosteum remained viable in the radiated vascularized grafts, producing both bone union and increased bone turnover, neither of which were evident to any significant extent in nonvascularized grafts. Bone union was achieved in vascularized and non-vascularized nonradiated bone. In the radiated group of dogs, union was only seen in the vascularized bone grafts.

Early postoperative continuous glucose monitoring in pancreas transplant recipients.  

PubMed

Continuous glucose monitoring (CGM) is used in people with type 1 diabetes to help with insulin treatment regimens. Its value in whole-organ pancreas transplantation (PT) is largely unknown. This study aimed to use CGM to assess the metabolic profile of pancreas transplant recipients in the early post-transplant period. We studied CGM data in 30 PT recipients and related findings to an early oral glucose tolerance test (OGTT). Complete data were available for 26 recipients. Seven days after a PT, normoglycaemia was present 77.9% of the time. Hypoglycaemic events (glucose <3.9 mmol/l) occurred in 10 of 26 (38.5%) of the cohort, but were infrequent (present 1.4% of the time). Hyperglycaemia (glucose >7.8 mmol/l) was present for 20.7% of the study period and correlated with a diagnosis of abnormal glucose tolerance. Whilst normoglycaemia is successfully achieved for the majority of the time after PT, hypoglycaemia can occur. Hyperglycaemia is more common and correlates well with the early postoperative OGTT, which is associated with graft failure. CGM is easier to perform and provides 24-h data that could inform clinical decision-making in patients in the postoperative period. PMID:25689138

Nach der Quantentheorie sind Schwarze Löcher nicht wirklich schwarz. Sie verhalten sich wie thermodynamische Systeme, besitzen also eine Temperatur und eine Entropie. Folglich strahlen sie Energie ab, verlieren an Masse und können dadurch vergehen. Kommt dabei die Information über den Stern, aus dem das Schwarze Loch ursprünglich entstand, wieder zurück? Nach dem klassischen Keine-Haare-Theorem würde man erwarten, dass alle Information verloren geht: Das Loch ist durch seine Masse, seinen Drehimpuls und seine (eventuelle) elektrische Ladung vollständig charakterisiert. Diese und andere Fragen, etwa zur Entropie, wird nur eine Theorie der Quantengravitation endgültig beantworten können. Ihre Konstruktion bleibt auch im 21.

Kindliche Leukämien und EMF-Expositionen in der Umgebung hochfrequenter Sendestationen (KiSS) - Fragestellung und Studienbeschreibung  

NASA Astrophysics Data System (ADS)

Im Rahmen einer Fall-Kontroll-Studie wird untersucht, ob es einen Zusammenhang zwischen dem Leukämierisiko bei Kindern und der Exposition gegenüber elektromagnetischen Feldern in der Umgebung leistungsstarker Sendestationen von Rundfunk und Fernsehen gibt. Bislang wurden fünf Studien im Umkreis von Rundfunksendeanlagen durchgeführt. Deren Aussagekraft ist jedoch durch eine grobe Expositionsabschätzung und ihren ökologischen Studienansatz ohne individuelle Expositionsbestimmung limitiert. Wesentliches Element der hier vorgestellten Studie ist dagegen eine individuelle Expositionsabschätzung, die zum einen auf der Geocodierung von Wohnadressen und Expositionspunktquellen und zum andern auf den tatsächlichen Strahlungsleistungen und Betriebsdaten der Senderbetreiber beruht. Das Studiengebiet besteht aus den Umgebungen von 17 leistungsstarken AM-Mittelwellensendern und 8 UKW-FM- bzw. analogen TV-Sendern in Westdeutschland. Zur Studienpopulation gehören alle im Diagnosezeitraum von 1984 bis 2003 aufgetretenen Fälle, die im Studiengebiet leben bzw. gelebt haben. Als Fälle werden alle Kinder definiert, die zum Zeitpunkt der Diagnose zwischen 0-14 Jahren alt waren, bei denen eine primäre Leukämie diagnostiziert wurde und die dem Deutschen Kinderkrebsregister bekannt sind. Jedem Fallkind werden 3 gleich alte Kontrollkinder gleichen Geschlechts aus der gleichen Senderumgebung gegenübergestellt. Möglich wurde diese Untersuchung durch die Förderung durch Mittel des Deutschen Mobilfunkforschungsprogramms sowie durch die Mitarbeit aller relevanten Senderbetreiber und des Deutschen Kinderkrebsregisters an der Universität Mainz. Sie soll bis August 2007 abgeschlossen sein.

Recent evidence suggests that preoperative executive dysfunction and depression may predict postoperative delirium; however, the combined effect of these risk factors remains unknown. We therefore examined the association between preoperative executive function, depressive symptoms, and established clinical predictors of postoperative delirium among 998 consecutive patients undergoing major non-cardiac surgery. Methods Nine hundred ninety eight patients were screened for postoperative delirium (n = 998) using the Confusion Assessment Method as well as through retrospective chart review. Patients underwent cognitive, psychosocial, and medical assessments preoperatively. Executive function was assessed using the Concept Shifting Task, Letter-Digit Coding, and a modified Stroop Color Word Interference Test. Depression was assessed by the Beck Depression Inventory. Results Preoperative executive dysfunction (P = .007) and greater levels of depressive symptoms (P = .049) were associated with a greater incidence of postoperative delirium, independent of other risk factors. Secondary analyses of cognitive performance demonstrated that the Stroop Color Word Interference Test, the executive task with the greatest complexity in this battery, was more strongly associated with postoperative delirium than simpler tests of executive function. Furthermore, patients exhibiting both executive dysfunction and clinically significant levels of depression were at greatest risk for developing delirium postoperatively. Conclusions Preoperative executive dysfunction and depressive symptoms were predictive of postoperative delirium among non-cardiac surgical patients. Executive tasks with greater complexity are more strongly associated with postoperative delirium relative to tests of basic sequencing. PMID:19326492

The importance of the postoperative anesthetic visit: do repeated visits improve patient satisfaction or physician recognition?  

PubMed

This study evaluates whether repeated postoperative visits by the anesthesiologist improve patient ability to recall the anesthesiologist's name and the patient's perception of and satisfaction with anesthesia services. In a randomized, prospective trial, 144 patients with an anticipated postoperative length of stay of at least three days were enrolled in three groups: Group A patients (n = 48) had one postoperative visit, Group B (n = 48) had two postoperative visits, and Group C (n = 48) had three postoperative visits. All postoperative visits were performed by the attending anesthesiologist on consecutive postoperative days. Patients were contacted two days after their last postoperative visit to complete a study questionnaire. Patients were able to recall the anesthesiologist's name significantly less frequently than the surgeon's name, and there was no difference in name recall among groups. Recall was not affected by patient age, sex, or ASA physical status; the mode of contact (telephone versus personal visit); the anesthesiologist's gender; the presence of preoperative medication; or the identity of the preoperative evaluator. Patients could identify the anesthesiologist's gender approximately 85% of the time, regardless of group, and were more likely to identify female anesthesiologists (P = 0.026, odds ratio 3.3). Patient evaluation of hospital, surgical, and anesthesia care was favorable in all groups and did not vary with group. Increasing the number of postoperative visits does not improve patient name recognition of the anesthesiologist or increase patient satisfaction with or perception of anesthesia services.

Postoperative Delayed Duodenum Perforation following Elective Laparoscopic Cholecystectomy.  

PubMed

Background. Duodenum injury is extremely rare complication of laparoscopic cholecystectomy with potentially fatal consequences. Methods. Over the past 13-year period, 3000 laparoscopic cholecystectomies were performed in our institution. Duodenum injury only occurred in one patient recently who had undergone gastrectomy owing to duodenal diverticulum. The diagnosis and management of this rare complication of laparoscopic cholecystectomy are described, and the literature is reviewed. Results. We present this case of duodenum injury on the fourth postoperative day after selective laparoscopic cholecystectomy was treated successfully by percutaneous needle aspiration and catheter drainage. The hospital stay was 26 days. No abscess recurred during the follow-up period. Conclusion. Duodenum injuries are extremely rare complications of laparoscopic cholecystectomy with potentially fatal consequences if not promptly recognized and treated. Sonographically guided percutaneous needle aspiration and catheter drainage can be used to treat the intraperitoneal abscess. Billroth II subtotal gastrectomy and gastrojejunostomy were beneficial for the treatment. PMID:24790609

Fournier's Gangrene as a Postoperative Complication of Inguinal Hernia Repair  

PubMed Central

Fournier's gangrene is the necrotizing fasciitis of perianal, genitourinary, and perineal regions. Herein, we present a case of scrotal Fournier's gangrene as a postoperative complication of inguinal hernia repair. A 51-year-old male with giant indirect hernia is presented. Patient underwent inguinal hernia repair, and after an unproblematic recovery period, he was discharged. He applied to our outpatient clinic on the fifth day with swollen and painful scrotum and it turned out to be Fournier's gangrene. Polypropylene mesh was not infected. Patient recovered and was discharged after repeated debridements. Basic principles in treatment of Fournier's gangrene are comprised of initial resuscitation, broad-spectrum antibiotics therapy, and early aggressive debridement. In the management of presented case, aggressive debridement was made right after diagnosis and broad-spectrum antibiotics were given to the hemodynamically stable patient. In these circumstances, the important question is whether we could prevent occurrence of Fournier's gangrene. PMID:25506030

Brain peptides and the modulation of postoperative gastric ileus.  

PubMed

Postoperative ileus (POI) develops after abdominal surgery irrespective of the site of surgery. When prolonged, POI can lead to longer hospitalization times and higher healthcare costs. Moreover, it is associated with complaints for the patient. In order to develop new strategies to treat this condition, a deeper understanding of the pathophysiology of the POI is necessary. This review will focus on brain peptides (ghrelin, nesfatin-1, somatostatin, corticotropin-releasing factor, thyrotropin-releasing hormone and calcitonin gene-related peptide) involved in the mediation of POI and the possible modulation of these pathways to shorten the time of POI. Lastly, the role of vagal signaling or chewing gum as potential treatment strategies of alleviating symptoms of POI is discussed. PMID:24999843

Inflammation Induced by Perfluorocarbon Liquid: Intra- and Postoperative Use  

PubMed Central

Perfluorocarbon liquids (PFCLs) are useful and safe surgical tools in vitreoretinal surgery. The use of PFCL as a tamponade has been controversial due to the corneal toxicity, retinal infiltration, and inflammatory reaction in experimental studies. Several authors have studied in humans the anatomical and functional outcome and adverse effects of perfluorocarbon liquids used as short-, medium-, and long-term tamponade. PFCLs develop dispersion a few days after injection and droplets may move into the anterior chamber and cause corneal endothelial damage. When PFCLs are used as postoperative tamponades for more than one week, a foreign-body inflammatory reaction is observed in up to 30% of cases but such a reaction does not induce PVR, and it resolves after removal of PFCLs. Although most clinical studies have found no signs of retinal toxicity such as progressive visual acuity deterioration or macular anatomical changes, few performed ERG or retinal histological analysis.

Does postoperative hand elevation reduce swelling? A randomized study.  

PubMed

The purpose of this study was to assess the effect of limb elevation on hand swelling after surgery. We prospectively randomized 113 patients undergoing fasciectomy or a trapeziectomy into one of two groups. The first group had the hand elevated postoperatively and the hands of the second group were not elevated. Hand swelling was assessed using a volumetric method. Although the swelling was less in the elevated group this did not reach statistical significance. Subgroup analysis revealed no further significant differences. There were no complications in patients who did not have limb elevation. This study does not support the routine use of elevation for 24 hours after fasciectomy for Dupuytren's disease and trapeziectomy to reduce hand swelling. PMID:20118124

[Some aspects of surgical treatment of postoperative ventral hernia].  

PubMed

The results of surgical treatment of of 392 patients with postoperative ventral hernia are discussed. The algorithm of treatment of patients with large hernias was developed. Special preoperative management by dosed pneumocompression in an antioverload costume makes it possible to avoid menacing complications after the operation, which are caused by increased intraabdominal pressure. Test for tolerance to increase of intraabodominal pressure allowed prognostication of the character of the operative intervention: with or without decrease of the volume of the abdominal cavity (autoplasty or alloplasty, respectively). Prevention of wound complications consisted in control of infection, improvement of operative techniques, and use of modern surgical instruments. The prevention of recurrent hernias should be directed at correct choice of the method of plastics and removal of wound complications. PMID:7745938

Detecting hypovolemia in postoperative patients using a discrete Fourier transform.  

PubMed

In the present paper, an attempt was made to find waveform-derived variables that would be useful for a more precise diagnosis of hypovolemia. In attempting this, arterial blood pressure graphs of 18 hypovolemic postoperative patients were analysed using a discrete Fourier transform. Using a paired samples t-test, the amplitude of the first harmonic (A1) is shown to be significantly higher in normovolemic cases than in hypovolemic ones (p<0.001). Based on the values of A1, a preliminary study was performed in which an additional group of 14 hypovolemic and 14 normovolemic patients were categorized into hypovolemic and normovolemic groups using logistic regression. The method proved to be successful in identifying hypovolemic patients: the prediction was correct in 80% and wrong only in 20%, indicating that A1 is potentially a useful parameter in detecting hypovolemia.

Incidence of postoperative hypothermia and the relationship to clinical variables.  

PubMed

A prospective, quantitative, correlational study was conducted to determine the incidence of postoperative hypothermia and the relationship of hypothermia to numerous clinical variables previously studied. The study reflects the researchers' interest in updating previous data regarding the incidence of hypothermia. Although hypothermia remains a significant clinical concern, interventions aimed at minimizing hypothermia have evolved over the past 20 years, thus prompting new interest in determining the extent to which hypothermia exists in today's PACU patients. A convenience sample of 287 adult, nonemergency patients scheduled for surgery were included in the study. Hypothermia (temperature <36°C) was demonstrated in only 4% of the sample (N = 287). Because of the low incidence of hypothermia, correlation statistics were not performed. The study provides a foundation for future research regarding this important clinical phenomenon while offering evidence supporting efforts to avoid hypothermia in today's surgical patients.

Changes in vision after non-ophthalmic surgery are a serious complication that can have devastating consequences due to its potential irreversibility. This not only leads to medical problems, but also legal ones. Many causes that affect sight during the peri-operative period have been identified, whether due to optic nerve damage or of extra-ocular origin (in the neuro-optic pathways and/or cerebral cortex). AU these may have a multifactorial origin, and there is still controversy as regards it pathogenesis and treatment. We present the case of a thoracic surgery patient who had a bilateral amaurosis in the post-operative period, which had a favourable outcome. PMID:22985757

Prevention and management of postoperative urinary retention after urogynecologic surgery  

PubMed Central

Postoperative urinary retention (POUR) is a frequent consequence of gynecologic surgery, especially with surgical correction of urinary incontinence and pelvic organ prolapse. Estimates of retention rates after pelvic surgery range from 2.5%–43%. While there is no standard definition for POUR, it is characterized by impaired bladder emptying, with an elevation in the volume of retained urine. The key to management of POUR is early identification. All patients undergoing pelvic surgery, especially for the correction of incontinence or prolapse, should have an assessment of voiding function prior to discharge. There are several ways to assess voiding function – the gold standard is by measuring a postvoid residual. Management of POUR is fairly straightforward. The goal is to decompress the bladder to avoid long-term damage to bladder integrity and function. The decision regarding when to discontinue catheter-assisted bladder drainage in the postoperative period can be assessed in an ongoing fashion by measurement of postvoid residual. The rate of prolonged POUR beyond 4 weeks is low, and therefore most retention can be expected to resolve spontaneously within 4–6 weeks. When POUR does not resolve spontaneously, more active management may be required. Techniques include urethral dilation, sling stretching, sling incision, partial sling resection, and urethrolysis. While some risk of POUR is inevitable, there are risk factors that are modifiable. Patients that are at higher risk – either due to the procedures being performed or their clinical risk factors – should be counseled regarding the risks and management options for POUR prior to their surgery. Although POUR is a serious condition that can have serious consequences if left untreated, it is easily diagnosed and typically self-resolves. Clinician awareness of the condition and vigilance in its diagnosis are the key factors to successful care for patients undergoing surgical repair. PMID:25210477

Optimized multisite ventricular pacing in postoperative single-ventricle patients.  

PubMed

Ventricular dyssynchrony is associated with morbidity and mortality after palliation of a single ventricle. The authors hypothesized that resynchronization with optimized temporary multisite pacing postoperatively would be safe, feasible, and effective. Pacing was assessed in the intensive care unit within the first 24 h after surgery. Two unipolar atrial pacing leads and four bipolar ventricular pacing leads were placed at standardized sites intraoperatively. Pacing was optimized to maximize mean arterial pressure. The protocol tested 11 combinations of the 4 different ventricular lead sites, 6 atrioventricular delays (50-150 ms), and 14 intraventricular delays. Optimal pacing settings were thus determined and ultimately compared in four configurations: bipolar, unipolar, single-site atrioventricular pacing, and intrinsic rhythm. Each patient was his or her own control, and all pacing comparisons were implemented in random sequence. Single-ventricle palliation was performed for 17 children ages 0-21 years. Pacing increased mean arterial pressure (MAP) versus intrinsic rhythm, with the following configurations: bipolar multisite pacing increased MAP by 2.2 % (67.7 ± 2.4 to 69.2 ± 2.4 mmHg; p = 0.013) and unipolar multisite pacing increased MAP by 2.8 % (67.7 ± 2.4 to 69.6 ± 2.7 mmHg; p = 0.002). Atrioventricular single-site pacing increased MAP by 2.1 % (67.7 ± 2.4 to 69.1 ± 2.5 mmHg: p = 0.02, insignificant difference under Bonferroni correction). The echocardiographic fractional area change in nine patients increased significantly only with unipolar pacing (32 ± 3.1 to 36 ± 4.2 %; p = 0.02). No study-related adverse events occurred. Multisite pacing optimization is safe and feasible in the early postoperative period after single-ventricle palliation, with improvements in mean arterial pressure and fractional area shortening. Further study to evaluate clinical benefits is required. PMID:24827078

DNA patterns in parathyroid disease predict postoperative parathyroid hormone secretion.  

PubMed

Flow cytometric analysis of the nuclear deoxyribonucleic acid (DNA) content of parathyroid glands excised from patients with hypercalcemic hyperparathyroidism has identified three distinct DNA patterns. The most frequent pattern showed a high percentage of cells with tetraploid DNA, which indicated an increase in the G2 and M phase of the cell cycle. Thirty-four patients were found to have abnormal tetraploid DNA content. One patient had a normal diploid pattern, and seven were found to have an aneuploid DNA population in their excised parathyroid glands. This unexpected finding of aneuploid DNA appears to be an unique feature of these endocrine glands because they have no histologic or clinical characteristics of malignant change. All patients have remained normocalcemic and clinically well after excision of only grossly enlarged glands. Postoperative parathyroid hormone (PTH) levels were correlated in 17 patients with DNA analyses of biopsy specimens from 30 normal-sized glands which were left in situ. Seven patients with elevated PTH postoperatively had high tetraploid or aneuploid DNA in all 13 glands from which biopsy specimens had high tetraploid or aneuploid DNA in all 13 glands from which biopsy specimens had been taken. In 10 patients with normal PTH levels, six had normal diploid patterns, whereas four had high tetraploid DNA in their gland biopsy specimens. DNA content present in biopsy specimens of normal-sized, in situ glands was predictive (p less than 0.042) of parathyroid gland secretory activity. These findings suggest that the stimulus for parathyroid gland hyperfunction often affects more than a single enlarged gland and persists after clinical cure, as shown by a more rapid cell turnover in some remaining glands and continued hypersecretion of hormone.

Attacking Postoperative Metastases using Perioperative Oncolytic Viruses and Viral Vaccines  

PubMed Central

Surgical resection of solid primary malignancies is a mainstay of therapy for cancer patients. Despite being the most effective treatment for these tumors, cancer surgery has been associated with impaired metastatic clearance due to immunosuppression. In preclinical surgery models and human cancer patients, we and others have demonstrated a profound suppression of both natural killer (NK) and T cell function in the postoperative period and this plays a major role in the enhanced development of metastases following surgery. Oncolytic viruses (OV) were originally designed to selectively infect and replicate in tumors, with the primary objective of directly lysing cancer cells. It is becoming increasingly clear, however, that OV infection results in a profound inflammatory reaction within the tumor, initiating innate and adaptive immune responses against it that is critical for its therapeutic benefit. This anti-tumor immunity appears to be mediated predominantly by NK and cytotoxic T cells. In preclinical models, we found that preoperative OV prevents postoperative NK cell dysfunction and attenuates tumor dissemination. Due to theoretical safety concerns of administering live virus prior to surgery in cancer patients, we characterized safe, attenuated versions of OV, and viral vaccines that could stimulate NK cells and reduce metastases when administered in the perioperative period. In cancer patients, we observed that in vivo infusion with oncolytic vaccinia virus and ex vivo stimulation with viral vaccines promote NK cell activation. These preclinical studies provide a novel and clinically relevant setting for OV therapy. Our challenge is to identify safe and promising OV therapies that will activate NK and T cells in the perioperative period preventing the establishment of micrometastatic disease in cancer patients.

Management of postoperative gastrointestinal leakage with autologous stromal vascular fraction.  

PubMed

To assess the efficacy of using autologous stromal vascular fraction (SVF) to promote healing of controlled fistula tracts in the management of postoperative upper gastrointestinal leakage. This is an experimental study conducted on 10 experimental rabbits. Animal models were divided into the SVF group which received an autologous SVF and the control group which did not receive the implantation. Surgery was performed on both groups to induce a gastric leak and create a controlled fistula tract between the leakage site in the stomach and the skin. After 2 weeks, surgery was performed on the SVF group to harvest, process and then implant the autologous SVF in the fistula tract. Animal models were followed up and their fistula tracts were evaluated for healing by gross and microscopic examination of the fistula tracts before the SVF implantation and at 24 hours, 1 week, 2 weeks and 3 weeks after implantation. The control group revealed no closure of fistula tracts by the 3(rd) week after implantation and there were no signs of inflammation or drainage. On the other hand, the SVF group showed signs of healing process with progressive closure of the fistula tract to about 95% by the 3(rd) week after implantation. The use of autologous SVF implantation to promote the healing of controlled fistula tracts seems to be a novel, safe and effective method in the management of postoperative upper gastrointestinal leakage. It could prevent reoperation and reduce hospital stay, morbidity and mortality. These results are promising and provide support for further clinical studies. PMID:25875560

Predictors of physical functioning in postoperative brain tumor patients.  

PubMed

A cross-sectional predictive design was used to study the relationships among recovery symptoms, mood state, and physical functioning and to identify predictors of physical functioning in patients who underwent surgery for brain tumor at the first follow-up visit (2 weeks) after hospital discharge. The sample included 88 patients who were 18 years or older, had full level of consciousness, and underwent first-time surgery for brain tumor without other adjuvant treatments from a tertiary hospital in Bangkok, Thailand. Descriptive statistics, Pearson product-moment correlation coefficient, and multiple regression were used for data analysis. The results revealed that most participants were women (75%) with an average age of 45.18 ± 11.49 years, having benign brain tumors (91%) and pathological results as meningioma (48.9%). The most common recovery symptoms were pain (mean = 3.2, SD = 2.6) and sleep disturbance (mean = 3.1, SD = 3.0). As for mood state, the problem of confusion was found the most (mean = 4.6, SD = 2.7). The physical functioning problem found the most was work aspect (mean = 66.3, SD = 13.3). Recovery symptoms had positive relationships with physical functioning and mood state (r = .406, .716; p < .01), respectively. At the same time, mood state had positive relationships with physical functioning (r = .288, p < .01). Recovery symptoms, total mood disturbance, fatigue, and vigor were statistically significant predictors of physical functioning and could explain variance of postoperative physical functioning in these patients at 2 weeks after discharge by 35%. Total mood disturbance was the strongest predictor of physical functioning followed by vigor, fatigue, and recovery symptom, respectively. Interventions to improve physical functioning in postoperative brain tumor patients during home recovery should account for not only recovery symptom management but also mood state. PMID:25565598

Wien mit der Bitte, den Unterschied der Schwingungsdauer eines Uranpendels und eines Bleipendels sowie die Proportionalität der trägen und schweren Massen eines Blei- und eines Urangewichts auszumessen, und zwar mit einer Drehwage. Der Brief macht es klar, dass Einstein bei der Aufstellung des

Factors contributing to poor post-operative abdominal pain management in adult patients: a review

Post-operative abdominal pain management can be a major issue facing medical and nursing staff in daily clinical practice. Effective pain control reduces post-operative morbidity as well as facilitates rehabilitation and accelerates recovery from surgery. In turn, poor pain control has been shown to alter body metabolic response that can lead to delayed recovery, with subsequent prolonged hospital stay and increased

The Importance of Pre and Postoperative Physical Activity Counseling in Bariatric Surgery

There is increasing evidence that physical activity (PA) can enhance weight loss and other outcomes after bariatric surgery. However, most preoperative patients are insufficiently active, and without support, fail to make substantial increases in their PA postoperatively. This review provides the rationale for PA counseling in bariatric surgery and describes how to appropriately tailor strategies to pre- and postoperative patients. PMID:22710705

The aim of this randomized controlled trial was to determine the effect of jaw relaxation, music and the combination of relaxation and music on postoperative pain after major abdominal surgery during ambulation and rest on postoperative days 1 and 2. Opioid medication provided for pain, following abdominal surgery, does not always give sufficient relief and can cause undesired side effects.

The incidence of postoperative ileus in patients who underwent robotic assisted radical prostatectomy  

PubMed Central

Introduction Our aim was to examine the incidence and risk factors of postoperative ileus among patients who underwent robot–assisted radical prostatectomy (RARP). Material and methods We retrospectively reviewed 239 patients who underwent RARP transperitoneally between February 2009 and December 2011. Patients switched to open surgery were excluded. We defined postoperative ileus as intolerance of a solid diet continued until the third postoperative day and beyond. By Clavien classification, we evaluated the perioperative complications that cause or contribute to postoperative ileus. Similarly, we analyzed the impact of anesthesia risk score on the incidence of postoperative ileus. Results The study included 228 patients. The mean period to tolerate solid food was 1.24 days. Only 6 patients experienced postoperative ileus, all of whom were treated with a conservative approach. The two groups differed significantly in the duration of abdominal drainage, hospital stay, modified Clavien classification, and the presence of comorbidity diabetes mellitus (P <0.5 for all factors). Multiple logistic regression analysis revealed that diabetes mellitus was an independent risk factor for postoperative ileus. Conclusions We suggest that diabetes mellitus is an independent risk factor for postoperative ileus in patients undergoing robot–assisted radical prostatectomy. PMID:24982775
