Randomized Controlled Trial Clinical Trial
[Wound infiltration with bupivacaine following pelviscopy does not reduce postoperative pain intensity. Results of a placebo-controlled, double-blind study].
The analgetic efficacy of intraoperative infiltration with bupivacaine 0.5% or saline of the skin incisions for the endoscopic trocars was examined in 30 female patients following operative endoscopic pelviscopy in a double-blind study. Infiltration of the peritoneum, abdominal wall, and subcutaneously was performed by endoscopic view before skin suture. There were no significant differences between the two groups in age, duration of surgery, operative technique, intensity of preoperative acute and chronic pain, or state of anxiety. ⋯ Pain due to skin incision was noted less, but in equal numbers in both groups. Of the patients in the bupivacaine group 77% and in the control group 80% started with PCA due to increasing pain scores within 60 to 120 min. The numbers of tramadol demands and given doses did not differ (Fig. 2).(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial
[Ondansetron as prophylaxis for postoperative nausea and vomiting. A prospective randomized double-blind comparative study with droperidol].
Ondansetron, a selective 5-HT3 receptor antagonist, has recently been shown, in a dose of 8 mg, to be superior to 1.25 mg droperidol in preventing postoperative vomiting. There are indications that a dose of 4 mg of ondansetron may be just as effective in reducing postoperative nausea and vomiting as a dose of 8 mg. The aim of this study was to evaluate the efficacy and the adverse effects of 4 mg ondansetron in the prevention of postoperative nausea and vomiting compared to droperidol in patients undergoing surgery with inhalation anaesthesia supplemented with alfentanil. ⋯ CONCLUSION. Our results show that for the prevention of postoperative nausea and vomiting 4 mg of Ondansetron was inferior to 1.25 mg of droperidol. The drugs were given intravenously prior to general anaesthesia for minor gynaecological surgery with nitrous oxide and enflurane in oxygen supplemented with small boluses of alfentanil.

Randomized Controlled Trial Comparative Study Clinical Trial
[Ondansetron versus droperidol. Postoperative treatment against nausea and vomiting. Comparison of action, adverse effects and acceptance by gynecologic inpatients].
Ondansetron is more effective than a placebo in treating postoperative nausea and vomiting (PONV), but it has not been proved to be superior to established antiemetics for prophylaxis or therapy. We compared ondansetron vs droperidol for the treatment of PONV. ⋯ Ondansetron (8 mg) and droperidol (1.25 mg) proved to be equally effective when used as a postoperative antiemetic. Both drugs showed similar side-effects. Due to differences in methods it was difficult to compare our results to those obtained in other studies.

Randomized Controlled Trial Comparative Study Clinical Trial
[Glucose-xylitol 35% (1:1) versus glucose 40%. Effectiveness and metabolic effects after major surgery].
Injury and stress are accompanied by a characteristic hormonal response and altered energy utilisation. Hyperglycaemia and negative nitrogen (N) balance are the leading symptoms of the metabolic changes in the post-operative state. In a prospective, randomised study the efficacy and metabolic effects of glucose-xylitol (GX) 35% (1:1) versus glucose (G) 40% were investigated in patients undergoing major surgery. ⋯ Similar blood G profiles were in accordance with comparable glucagon and insulin levels. Because of the high standard deviations of N balances, differences in efficacy could not be proven. A significantly lower level of pseudocholinesterase (PCHE) for G40% on day 7 might indicate enhanced hepatic protein synthesis in the GX group.
