Randomized Controlled Trial Clinical TrialOndansetron versus droperidol or placebo to prevent nausea and vomiting after otologic surgery.
This study compares the preoperative administration of ondansetron with that of droperidol or saline solution for the prevention of nausea and vomiting in otologic surgery patients. A total of 120 otherwise healthy individuals were randomly assigned to receive either saline solution, ondansetron (4 mg intravenously), or droperidol (25 microg/kg intravenously) before anesthetic induction. Intraoperative and postanesthesia care unit times were recorded along with incidence of nausea, vomiting, pain, nausea and recovery scores, and the administration of rescue antiemetics. ⋯ Fewer women in the ondansetron group vomited than in the other two groups. Ondansetron 4 mg intravenously is as effective as droperidol and better than saline solution in preventing nausea and vomiting in patients undergoing otologic surgery. No cost advantage as determined by lower use of rescue antiemetics or shorter postanesthesia care unit times was noted after ondansetron therapy.

Randomized Controlled Trial Clinical TrialThe use of preoperative lidocaine to prevent stridor and laryngospasm after tonsillectomy and adenoidectomy.
The most important complications from tonsillectomy and adenoidectomy are bleeding, stridor, and laryngospasm. This controlled, double-blind study was designed to investigate the effects of topical and intravenous lidocaine on stridor and laryngospasm. A total of 134 patients scheduled for elective tonsillectomy and/or adenoidectomy were randomly separated into four groups. ⋯ In the intravenous lidocaine group, patients were given 1 mg/kg of 2% lidocaine before extubation, and the same amount of 0.9% NaCl was given to the second control group. Postoperative stridor, laryngospasm, cyanosis, bleeding, sedation degree, and respiratory depression were observed, and plasma lidocaine levels were measured. Both topical and intravenous lidocaine groups revealed less stridor and laryngospasm than the control groups, and no difference was found between the topical and intravenous lidocaine groups except the higher sedation scores in the early postoperative period for the intravenous lidocaine group.
