Randomized Controlled Trial Comparative Study Clinical TrialComparison of granisetron and droperidol in the prevention of vomiting after strabismus surgery or tonsillectomy in children.
This prospective, randomized, double-blinded study evaluated the antiemetic efficacy of granisetron and droperidol in 80 ASA physical status I children, aged 4-10 years, undergoing strabismus surgery or tonsillectomy with or without adenoidectomy. After anaesthetic induction, the patients received either granisetron (40 micrograms.kg-1, n = 40) or droperidol (50 micrograms.kg-1, n = 40) intravenously. ⋯ The requirement for rescue antiemetic therapy for the treatment of two or more episodes of vomiting was 0% with granisetron and 18% with droperidol (P = 0.001). In conclusion, granisetron was superior to droperidol in reducing the incidence and frequency of postoperative vomiting in paediatric patients.

Randomized Controlled Trial Comparative Study Clinical TrialRecovery characteristics of propofol anaesthesia, with and without nitrous oxide: a comparison with halothane/nitrous oxide anaesthesia in children.
Few studies have examined whether nitrous oxide influences the recovery characteristics of propofol anaesthesia. The present study examined the effect of nitrous oxide on the recovery characteristics of propofol anaesthesia, and compared these data with those for halothane/nitrous oxide anaesthesia. Sixty children aged 3-12 years were assigned at random to receive one of three maintenance regimens: propofol with or without nitrous oxide (70%) or halothane/nitrous oxide (70%). ⋯ The time from discontinuation of anaesthesia to eye-opening (11 +/- 6 min), to response to commands (12 +/- 6 min), and to return of full wakefulness (21 +/- 10 min) after propofol/N2O were similar to those after propofol/O2, but significantly less (by approximately 30%) than those after halothane (P < 0.05). The overall incidence of emesis after propofol/N2O (53%) was greater than that after propofol/O2 (17%, P < 0.05) and comparable to that after halothane/N2O (58%). These data suggest that N2O has little effect on the rate of recovery after propofol, but significantly increases the incidence of postoperative emesis, thereby attenuating one of the main attributes of propofol anaesthesia.

Randomized Controlled Trial Clinical TrialSublingual midazolam premedication in children: a dose response study.
The purpose of this study was to evaluate various doses of sublingual midazolam premedication in children. In our prospective, double-blind, placebo-controlled trial, children (n = 102, age range 12 to 129 months) scheduled for day surgery were randomized to receive either midazolam in one of three doses (0.25, 0.5, or 0.75 mg.kg-1) or placebo. ⋯ Analysing all patients randomized, none of the children receiving placebo vs 28% receiving 0.25 mg.kg-1 (P = 0.02), 52% receiving 0.5 mg.kg-1 (P < 0.001), and 64% receiving 0.75 mg.kg-1 (P < 0.001) of midazolam showed satisfactory sedation (drowsy) at 15 min after administration. Children receiving the two higher doses of midazolam (0.5 and 0.75 mg.kg-1) accepted mask induction willingly, while the group receiving 0.25 mg.kg-1 resembled the placebo group (P < 0.05).
