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 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 Clinical Trial
Headache prevention following accidental dural puncture in obstetric patients.
To evaluate the efficacy of a prophylactic saline patch and a prophylactic blood patch in prevention of headache following accidental dural puncture in obstetric patients. ⋯ The results of this study suggest that the administration of a prophylactic epidural blood patch is highly effective in the prevention of headaches following dural puncture, with headache frequency reduced from 87.5% to 5%.

Randomized Controlled Trial Clinical Trial
Neuromuscular effects of succinylcholine following different pretreatments.
To study the neuromuscular effects (onset, intensity, and duration of block) of succinylcholine following different pretreatments. ⋯ Of the pretreatments used, only d-tubocurarine interferes with the neuromuscular blocking effects of succinylcholine. Chlorpromazine, which attenuates the muscle pains as well as the increase in creatine kinase and can be administered with the same convenience, may be a better pretreatment in the prevention of side effects of succinylcholine.

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.
