Predictive performance of'Diprifusor'TCI system in patients during upper abdominal surgery under propofol/fentanyl anesthesia

Objective:To evaluate the predictive performance of‘Diprifusor’TCI(target-controlled infusion)system for its betterapplication in clinical anesthesia.Methods:The predictive performance of a‘Diprifusor’TCI system was investigated in 27Chinese patients(16 males and 11 females)during upper abdominal surgery under total intravenous anesthesia(TIVA)withpropofol/fentanyl.Measnred arterial propofol concentrations were compared with the values predicted by the TCI infusion system.Performance was determined by the median performance error(MDPE),the median absolute performance error(MDAPE),thedivergence(the percentage change of the absolute PE with time),and the wobble(the median absolute deviation of each PE fromthe MDPE).Results:The median(range)values of 14.9%(-21.6%～42.9%)for MDPE,23.3%(6.9%～62.5%)for MDAPE,-1.9%h^(-1)(-32.7%～23.0% h^(-1))for divergence,and 18.9%(4.2%～59.6%)for wobble were obtained from 227 samples from all patients.For the studied population,the PE did not increase with time but with increasing target propofol concentration,particularly fol-lowing induction.Conclusions:The control of depth of anaesthesia was good in all patients undergoing upper abdominal surgicaloperation and the predictive performance of the‘Diprifusor’target controlled mthsion system was considered acceptable forclinical purposes.But the relatively bigger wobble showed that the pharmacokinetic model is not so suitable and requires im-provement.

Thinking in three's: Changing surgical patient safety practices in the complex modern operating room

The three surgical patient safety events, wrong site surgery, retained surgical items (RSI) and surgical fires are rare occurrences and thus their effects on the complex modern operating room (OR) are difficult to study. The likelihood of occurrence and the magnitude of risk for each of these surgical safety events are undefined. Many providers may never have a personal experience with one of these events and training and education on these topics are sparse. These circumstances lead to faulty thinking that a provider won't ever have an event or if one does occur the provider will intuitively know what to do. Surgeons are not preoccupied with failure and tend to usually consider good outcomes, which leads them to ignore or diminish the importance of implementing and following simple safety practices. These circumstances contribute to the persistent low level occurrence of these three events and to the difficulty in generating sufficient interest to resource solutions. Individual facilities rarely have the time or talent to understand these events and develop lasting solutions. More often than not, even the most well meaning internal review results in a new line to a policy and some rigorous enforcement mandate. This approach routinely fails and is another reason why these problems are so persistent. Vigilance actions alone havebeen unsuccessful so hospitals now have to take a systematic approach to implementing safer processes and providing the resources for surgeons and other stake-holders to optimize the OR environment. This article discusses standardized processes of care for mitigation of injury or outright prevention of wrong site surgery, RSI and surgical fires in an action-oriented framework illustrating the strategic elements important in each event and focusing on the responsibilities for each of the three major OR agents-anesthesiologists, surgeons and nurses. A Surgical Patient Safety Checklist is discussed that incorporates the necessary elements to bring these team members together and influence the emergence of a safer OR.

Continuous wound infusion of local anaesthetic agents following colorectal surgery:Systematic review and meta-analysis

AIM:To provide a specifi c review and meta-analysis of the available evidence for continuous wound infusion of local anaesthetic agents following midline laparoto-my for major colorectal surgery. METHODS: Medline, Embase, trial registries, conference proceedings and article reference lists were searched to identify randomised, controlled trials of continuous wound infusion of local anaesthetic agents following colorectal surgery. The primary outcomes were opioid consumption, pain visual analogue scores (VASs), return to bowel function and length of hospital stay. Weighted mean difference were calculated for continuous outcomes. RESULTS: Five trials containing 542 laparotomy wounds were eligible for inclusion. There was a sig- nificant decrease in post-operative pain VAS at rest on day 3 (weighted mean difference: -0.43; 95% CI: -0.81 to -0.04; P = 0.03) but not on post-operative day 1 and 2. Local anaesthetic infusion was associated with a signifi cant reduction in pain VAS on movement on all three post-operative days (day 1 weighted mean difference: -1.14; 95% CI: -2.24 to -0.041; P = 0.04, day 2 weighted mean difference: -0.97, 95% CI: -1.91to -0.029; P = 0.04, day 3 weighted mean difference: -0.61; 95% CI: 1.01 to -0.20; P = 0.0038). Local an- aesthetic wound infusion was associated with a signifi - cant decrease in total opioid consumption (weighted mean difference: -40.13; 95% CI: -76.74 to -3.53; P = 0.03). There was no signifi cant decrease in length of stay (weighted mean difference: -20.87; 95% CI: -46.96 to 5.21; P = 0.12) or return of bowel function (weighted mean difference: -9.40; 95% CI: -33.98 to 15.17; P = 0.45). CONCLUSION: The results of this systematic re- view and meta-analysis suggest that local anaesthetic wound infusion following laparotomy for major color- ectal surgery is a promising technique but do not pro- vide conclusive evidence of benefi t. Further research is required including cost-effectiveness analysis.

Transthoracic En-bloc Esophagectomy

In patients with esophageal carcinoma surgical resection remains the standard of curative treatment. For locally advanced tumors (pT1sm–pT3) transthoracic esophagectomy with extended lym- phadenectomy is the standard surgical procedure since it o?ers a complete removal of the primary tumor and possible lymph node metastases. This surgical resection is appropriate for squamous cell but also adenocarcinoma of the esophagus because both histological entities demonstrate a lymphatic spread to the abdominal compartment and the upper mediastinum. In-hospital mortality rates are between 6% and 9%; anastomotic leakage and pulmonary complications mainly contribute to postoperative morbidity. In terms of 5-year survival the transthoracic procedure o?ers a better prognosis compared to the transhiatal resection. 五笔字型计算机汉字输入技术

Glutamine dipeptide for parenteral nutrition in abdominal surgery:A meta-analysis of randomized controlled trials

AIM: To assess the clinical and economical validity of glutamine dipeptide supplemented to parenteral nutrition (PN) in patients undergoing abdominal surgery. METHODS: A meta-analysis of all the relevant randomized controlled trials (RCTs) was performed. The trials compared the standard PN and PN supplemented with glutamine dipeptide in abdominal surgery. RCTs were identified from the following electronic databases: the Cochrane Library, MEDLINE, EMBASE and ISI web of knowledge (SCI). The search was undertaken in April 2006. Literature references were checked by computer or hand at the same time. Clinical trials were extracted and evaluated by two reviewers independently. Statistical analysis was performed by RevMan4.2 software from Cochrane Collaboration. A P value of < 0.05 was considered statistically significant. RESULTS: Nine RCTs involving 373 patients were included. The combined results showed that glutamine dipeptide has a positive effect in improving postoperative cumulative nitrogen balance (weighted mean difference (WMD = 8.35, 95% CI [2.98, 13.71], P = 0.002), decreasing postoperative infectious morbidity (OR = 0.24, 95% CI [0.06, 0.93], P = 0.04), shortening the length of hospital stay (WMD= -3.55, 95% CI [-5.26, -1.84], P < 0.00001). No serious adverse effects were found. CONCLUSION: Postoperative PN supplemented with glutamine dipeptide is effective and safe to decrease the infectious rate, reduce the length of hospital stay and improve nitrogen balance in patients undergoing abdominal surgery. Further high quality trials in children and severe patients are required, and mortality and hospital cost should be considered in future RCTs with sufficient size and rigorous design.

Abdominal neurenteric cyst

Neurenteric cysts are extremely rare congenital anomalies, often presenting in the first 5 years of life, and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal abnormalities, but the latter may be absent in adults. Although usually located in the thorax, neurenteric cysts may be found along the entire spine. We present a 24-year-old woman admitted for epigastric pain, nausea, vomiting, low grade fever and leucocytosis. She underwent cystgastrostomy for a Ioculated cyst of the distal pancreas at the age of 4 years, which recurred when she was at the age of 11 years. Ultrasound and computer tomograghy （CT） scan revealed a 16 cmx 15 cm cystic mass in the body and tail of pancreas, with a 6-7 mm thickened wall. Laboratory data and chest X-ray were normal and spinal radiographs did not show any structural abnormalities. The patient underwent a complete cyst excision, and after an uneventful recovery, remained symptom-free without recurrence during the 5-year follow-up. The cyst was found to contain 1200 mL of pale viscous fluid. It was covered by a primitive singlelayered cuboidal epithelium, along with specialized antral glandular parenchyma and hypoplastic primitive gastric mucosa. Focal glandular groups resembling those of the body of the stomach were also seen. In addition, ciliary respiratory epithelium, foci of squamous metaplasia and mucinous glands were present. The wall of the cyst contained a muscular layer, neuroglial tissue with plexogenic nerve fascicles, Paccini corpuscle-like structures, hyperplastic neuroganglionar elements and occasional psammomatous bodies, as well as fibroblast-like areas of surrounding stroma. Cartilagenous tissue was not found in any part of the cyst. Immunohistochemistry confirmed the presence of neurogenic elements marked by S-100, GFAP, NF and NSE. The gastric epithelium showed mostly CK7 and EMA immunoexpression, and the respiratory epithelium revealed a CK8 and CK18 immunoprofile without CK 10/13 positive elements, though neither CEA or AFP positive cells were found. To our knowledge, this is the first reported case of an abdominally located neurenteric cyst with no associated spinal anomalies.

Clinical Research of a Modified Midfacial Degloving in a Maxillectomy (with a Report of a Typical Case)

OBJECTIVE To investigate the feasibility of employing a modified midfacial degloving in maxillectomy. METHODS Eight patients with carcinoma of the maxillary sinus underwent a modified midfacial degloving operation. The tumors were classified according to the 2002 AJCC system. The TNM staging of the cases was as follows： 1 T4aN0M0, 2 T3N0M0 and 5 T2N0M0. Of the 8 cases, 1 patient underwent extended maxillectomy; exenteration of the orbit; tumorectomy of the sphenomaxillary and infratemporal fossae. Two patients received a total maxillectomy, and 5 a partial resection of the maxilla. Postoperative pathological report： 4 well-differentiated squamous carcinoma, 2 moderately-differentiated squamous carcinoma, 1 mucoepidermoid carcinoma and 1 adenoid cystic carcinoma.RESULTS A modified midfacial degloving operation can sufficiently expose a field of operation, resect the tumor within a safe margin, and leave no facial cicatricles. One patient died of intracranial metastasis 8 months after operation. We observed no recurrences or metastasis in other patients during the period of follow-up.CONCLUSION The major advantages of employing the modified midfacial degloving in maxillectomy is that a facial incision can be avoided. It has an advantage of minimal invasive surgery

Severe hepatic trauma: surgical strategies

To probe into effective surgical procedures and improve the outcome of treatment for patients with severe hepatic injury. Methods: A retrospective study involving 113 patients with seve re hepatic trauma (AAST grade IV and V) during the past 12 years was carried out . Ninety eight patients underwent surgical treatment. Surgical interventions in cluding hepatectomy or direct control of bleeding vessels by finger fracture tec hnique with Pringle maneuver, selective ligation of hepatic artery, retrohepatic caval repair with total hepatic vascular occlusion, and perihepatic packing wer e mainly used. Results: In the 98 patients treated operatively, the survival r ate was 69.4 % (68/98). Among 40 patients with juxtahepatic venous injury (JH VI), 15 were cured with the maximum blood transfusion of 12 000 ml. Eight ca ses of Grade IV injury treated nonoperatively were cured. The percentage of fail ure of nonoperative management was 42.9 % (6/14). The overall mortality rate was 32.7 % (37/113), and 57% of the deaths were due to exsanguination. Conclusions: Reasonable surgical procedures based on classifica tion of hepatic injuries can increase the survival rate of severe liver trauma. Accurate perihepatic packing is effective in dealing with JHVI.

Peri-operative treatment of most severely head-injured patients

Objective:: To summarize the peri-operative experience from 53 patients with traumatic head injuries with GCS score 3-5. Methods: Fifty-three most severely head-injured patients with GCS score 3-5 were admitted to our department and treated operatively from Oct. 1994 to Jun. 1998 and the data were analyzed retrospectively. Results: Thirty-seven cases ( 69.8 %) survived, among them 28 ( 52.8 %) had a good recovery or moderate disability, and 9 (17%) had severe deficits. The other 16 ( 30.2 %) died after therapy. Conclusions: The prognosis of most severely head-injured patients could be improved by peri-operative treatment including premedical care, early evacuation of intracranial hematoma with large decompressive craniectomies, intracranial hypertension monitoring, moderate hypothermia therapy, effective prevention and treatment of cerebral vasospasm and complications.

Case Report:Surgical intervention of severe post-ERCP-pancreatitis accompanied with duodenum perforation

Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure widely used to diagnose and treat conditions of biliary or pancreatic ductal system. The post-ERCP severe acute pancreatitis (SAP) accompanied with duodenum perforation is rare but serious, remaining a challenge in clinic. In this study we report two such cases. Two Chinese women were treated for clinical suspicion of bile duct obstruction and underwent ERCP after admission. Both developed duodenum perforation and SAP after ERCP, and were managed in the intensive care unit (ICU) and required an organ-failure support. The surgical intervention of the peri-pancreatic debridement with lumber-abdominal compound incisions and postoperative washing and drainage was performed, and the two patients recovered well. The therapeutic effect of the peri-pancreatic debridement with lumber-abdominal compound incisions combined with postoperative washing and drainage in the patients of severe post-ERCP-pancreatitis (PEP) and duodenum perforation is satisfactory.

Total hip arthroplasty with cementless cups and femoral head autografts for patients with hip dysplasia and osteoarthritis

Objective: To evaluate the outcome of total hip arthroplasty (THA) with cementless cups and femoral head autografts for patients with hip dysplasia and osteoarthritis. Methods: Between 1995 and 2002, we implanted 23 cementless cups and femoral head autografts in 20 patients with hip dysplasia and osteoarthritis. In this study, a retrospective study was made on 21 hips in 20 patients (18 females and 2 males, aged 50 years on an average) with developmental hip dysplasia treated by THA with a cementless cup and femoral head autograft. The acetabular cup was placed at the level of the true acetabulum and all the patients required autogenous femoral head grafts due to acetabular deficiency. The average rate of the acetabular cup covered by the femoral head autograft was 31% (ranging from 10% to 45%). Eight hips had less than 25% cup coverage and thirteen between 25% and 50%. The average follow-up period was (4.7) years (range, 1-8 years). The replacing outcome was evaluated by modified Harris hip score. Preoperative and follow-up radiographs were made. Results: All the autografts were united to the host bones. No autograft was collapsed or no component from the hip was loosed in all the patients. According to the modified Harris hip score, the average hip score increased from 46 before operation to 89 at the final review. Before operation, the leg-length discrepancy was greater than 2 cm in all the patients except one with bilateral hip dysplasia. After operation, only 2 out of 20 patients had a leg-length discrepancy greater than 1 cm. Three hips showed minor bone resorption in the lateral portion of the graft, which did not support the cup. Three hips developed Grade 1 Brooker heterotopic ossification and one developed Grade 2. Conclusions: THA with a cementless cup and a femoral head autograft for patients with osteoarthritis resulted from hip dysplasia can result in favorable outcomes. This method can provide reliable acetabular fixation and restore the acetabular bone stock in patients with developmental hip dysplasia when the cementless cup covered by the graft does not exceed 50%.
