Randomized Controlled Trial Comparative Study Clinical Trial
Prophylactic antiemetics for laparoscopic cholecystectomy: a comparison of perphenazine, droperidol plus ondansetron, and droperidol plus metoclopramide.
To compare the prophylactic administration of ondansetron plus droperidol, droperidol plus metoclopramide, and perphenazine to determine effects on postoperative nausea, vomiting, and sedation after laparoscopic cholecystectomy. ⋯ These three drug regimens are equivalent for antiemetic prophylaxis before laparoscopic cholecystectomy.

An intravenous fluid bolus is not necessary before administration of intrathecal fentanyl for labor analgesia.
To determine if an intravenous (i.v.) fluid bolus is necessary to prevent any possible hemodynamic sequelae after administration of intrathecal fentanyl in laboring parturients. ⋯ Intrathecal fentanyl produces only minimal hemodynamic changes with or without prior fluid administration.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparative study of the dose-response and time course of action of rocuronium and vecuronium in anesthetized adult patients.
(1) To compare the dose-response relations of rocuronium and vecuronium in healthy adult patients anesthetized with nitrous oxide-oxygen-fentanyl-thiopental; and (2) to evaluate the time-course of action of two drugs following equipotent doses. ⋯ Compared with vecuronium, rocuronium is a low-potency, nondepolarizing relaxant, and its neuromuscular blocking potency is approximately 15% that of vecuronium in adult patients anesthetized with N2O and fentanyl. Following equipotent doses, the time-course of recovery for rocuronium is similar to that of vecuronium.

Preventing hypothermia: convective and intravenous fluid warming versus convective warming alone.
To test the hypothesis that warming intravenous (i.v.) fluids in conjunction with convective warming results in less intraoperative hypothermia (core temperature < 36.0 degrees C) than that seen with convective warming alone. ⋯ The combination of convective and fluid warming was associated with a decreased likelihood of patients leaving the operating room hypothermic. However, average final temperatures were greater than 36 degrees C in both groups, and intergroup differences were small. Care must be taken to avoid overheating the patient when both warming modalities are employed together.

Effects of nicardipine and labetalol on the acute hemodynamic response to electroconvulsive therapy.
To examine the acute hemodynamic effects of intravenous (i.v.) nicardipine and its ability to attenuate the hyperdynamic response to electroconvulsive therapy (ECT), when used alone or in combination with labetalol. ⋯ Nicardipine 2.5 mg i.v. bolus in combination with labetalol 10 mg i.v. was the most effective pretreatment regimen for preventing the acute hyperdynamic response to ECT. However, this combination produced a 20% decrease in MAP immediately prior to ECT and a lower MAP at the time of discharge.
