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.

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
[The effect of different types of anesthetic respirators on oxygenation and ventilation in infants during short-term anesthesia. A study using transcutaneous PO2 and PCO2 monitoring].
Monitoring of ventilation in infants is difficult and often not very reliable. In this study, transcutaneous measurement of blood gas tensions was used to investigate the influence of four different modes of ventilation on oxygenation and ventilation in anaesthetized infants. METHODS. ⋯ The group-specific differences in degree of dysventilation with manual ventilation show that the type of breathing system is important with regard to the size of the tidal volume delivered. Thus, tidal volumes will be unintentionally increased by the high fresh gas flow needed when a T-piece system is used. The lower flow and preadjusted pressure limit may prevent the delivery of excessive tidal volumes with the paediatric circuit system...

Randomized Controlled Trial Clinical Trial
[The optimal administration time for neostigmine following atracurium blockade. Kinetics of antagonists].
The aims of the study were: (1) to predict reversal time from intensive atracurium blockade; and (2) to determine the optimal time of neostigmine administration during recovery from atracurium blockade, i.e., the time at which the administration of neostigmine results in the shortest total recovery time (time from administration of last supplemental dose of atracurium to train-of-four [TOF] ratio 0.70), and at the same time results in the shortest time from administration of neostigmine to TOF ratio 0.70. ⋯ Reversal time can be predicted as 27.3 min - (0.89 x prereversal time (min), and the optimal time of neostigmine administration in atracurium blockade appears to be when TH1 is 1%-10%.
