Randomized Controlled Trial Clinical Trial
Propofol-nitrous oxide versus thiopental sodium-isoflurane-nitrous oxide for strabismus surgery in children.
To assess the quality of anesthesia and recovery and the frequency of postanesthetic retching and vomiting with propofol anesthesia for pediatric strabismus surgery. ⋯ Propofol induction and maintenance of anesthesia for strabismus surgery in children significantly lowers the frequency of postanesthetic retching and vomiting, but propofol is associated with pain and spontaneous movements at induction and a high frequency of oculocardiac reflexes during maintenance infusion.

Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized, double-blind pilot study examining the use of intravenous ondansetron in the prevention of postoperative nausea and vomiting in female inpatients.
To compare the efficacy and safety profiles of intravenous (IV) ondansetron (two 8 mg doses 8 hours apart) and a placebo when used in the prevention of postoperative nausea and emesis (vomiting or retching). ⋯ Prophylactic IV ondansetron appears to be safe and causes a significant reduction in the frequency and severity of postoperative nausea and emesis.

Randomized Controlled Trial Multicenter Study Clinical Trial
A double-blind, placebo-controlled pilot study examining the effectiveness of intravenous ondansetron in the prevention of postoperative nausea and emesis.
To compare the efficacy and safety profiles of ondansetron and a placebo when infused immediately prior to anesthesia induction for the prevention of postoperative nausea and emesis (vomiting or retching). ⋯ Ondansetron, infused IV before anesthesia induction, appears to be safe and effective when used in the prevention of postoperative nausea and emesis.

Randomized Controlled Trial Comparative Study Clinical Trial
Oral clonidine blunts the hemodynamic responses to brief but not prolonged laryngoscopy.
To determine whether a 300 micrograms dose of oral clonidine given 90 minutes prior to laryngoscopy and intubation provides hemodynamic protection from the stress of a brief (15-second) and/or a prolonged (45-second) laryngoscopy. ⋯ Oral clonidine, when used as a preoperative medication, affords hemodynamic protection to patients undergoing a 15-second laryngoscopy. However, the stress of a 45-second laryngoscopy may be too great or the 300 micrograms dose of clonidine too low to provide hemodynamic protection for patients in this group.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of midazolam, diazepam, and placebo as oral anesthetic premedicants in younger children.
To validate the superiority of higher-dose oral midazolam as an anesthetic premedicant in children 6 years of age and younger, to determine whether less expensive diazepam is a viable alternative oral premedicant in this age-group, and to assess the preoperative oxygenation effects of both benzodiazepines. ⋯ Even without premedication, a majority of children did not react negatively to an impending anesthetic. Therefore, neither midazolam nor diazepam appears to be necessary in most children younger than 6 years of age. Rather than implementing the routine use of an oral preoperative sedative, the challenge appears to be the selective identification of those children at risk for preanesthetic difficulties and psychological trauma.
