Hypertonic saline solution resuscitation in hemorrhagic shock dogs / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To find out the optimal concentration, infusion rate and dosage of saline for resuscitation.</p><p><b>METHODS</b>Forty-five dogs were used to establish hypovolemic shock models. The dogs were resuscitated with saline of different concentrations and different dosages under different infusion rates, and the resuscitation results were compared.</p><p><b>RESULTS</b>The best concentration was 7.5%, the best rate of infusion 20 ml/min (a volume equivalent to 15% of the shed blood) and the best dosage 5.71 ml/kg. The method was effective for resuscitation, the mean arterial pressure (MAP) could be elevated to 89% of the baseline, and this MAP could be kept for more than one hour.</p><p><b>CONCLUSIONS</b>Using 7.5% sodium chloride solution equivalent to 15% of the shed blood at an infusion rate of 20 ml/min can achieve a best resuscitation result.</p>

Analysis of risk factor of bile duct injury during laparoscopic cholecystectomy / 中国普通外科杂志

Objective To analyze risk factor of bile duct injury (BDI) during laparoscopic cholecystectomy (LC). Methods A retrospective population-based cohort study was carried out on 13878 patients undergoing LC from Apr 1994 to Dec 2003. Patients were divided into BDI group and non-BDI group. Factors with statistically significant differences between groups in anivariable analysis were selected to construct a multivariate logistic regression mode. Result Among 13878 LC procedures 38 BDI (0.27%) were identified. Factors which were of significant differences between groups in anivariable analysis includ diameter of common bile duct(?~2=5.92, P

The treatment of pancreatic pseudocyst / 中国普通外科杂志

Objective To analyze the diagnosis and treatment of pancreatic pseudocyst. Method This study included 46 pancreatic pseudocyst cases, 7 received conservative therapy, 12 received internal drainage, 9 received external drainage, 5 received sequential internal and external drainage and 13 received partial pancreatectomy. Result Cases receiving conservative therapy recovered well without recurrence, one case receiving internal drainage suffered from postoperative pancreatic fistula, one receiving external drainage was complicated with pancreatic fistula and recurrence developed in another 2 cases, one case undergoing partial pancreatectomy was complicated with postoperative pancreatic fistula. Conclusion Pancreatic pseudocyst should be managed individually according the course and patients' clinical condition.

Laparoscopic hepatectomy:a report of 20 cases / 中国普通外科杂志

Objective To evaluate the maneuvre of curettage and aspiration(LTCA) in laparoscopic hepatectomy. MethodsWe used Peng′s multifunctional operative dissector(PMOD) to perform laparoscopic liver transection by maneuvre of curettage and aspiration in 20 cases undergoing laparoscopic hepatectomy. Results Procedures were all successful. The recovery was uneventful without any complications. Mean operative time was 105 minutes, the average bleeding volume was 420 ml, the largest excised sample size was 10 cm?9 cm?7 cm. All patients were discharged within one week. ConclusionsThe new technique-LTCA can be used in laparoscopic hepatectomy, it has the advantages of clear anatomy, good exposure of canal construction, rapid liver transection, satisfactory hemostasis and clear operative field.
