Randomized Controlled Trial Comparative Study Clinical Trial
Incidence of nausea and vomiting in outpatients undergoing general anesthesia in relation to selection of intraoperative opioid.
To measure the incidence of nausea and vomiting in outpatients in relation to selection of, or withholding of, intraoperative opioid. ⋯ Opioid administration at the doses employed during induction of anesthesia does not promote postoperative nausea or vomiting, nor increase length of stay in the PACU.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective, randomized comparison of the Flotem Iie and Hotline fluid warmers in anesthetized adults.
To compare the fluid warming capabilities of the Hotline and Flotem IIe devices in surgical patients, and whether warming intravenous (i.v.) fluids with the Hotline device resulted in less hypothermia and less need for other warming methods compared with the Flotem IIe device. ⋯ The Hotline device delivered fluids to the patient at consistently warmer temperatures compared with the Flotem IIe device during actual clinical conditions. This was associated with maintenance of near normal core temperatures throughout the procedure in the Hotline group, and a decreased need for interventions such as forced-air warming and treatment for severe shivering.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of mivacurium dosage requirements during isoflurane and desflurane anesthesia.
To evaluate the dose requirement and recovery characteristics of mivacurium infusions during anesthesia with equipotent concentrations of either desflurane or isoflurane. ⋯ There were no differences in the dose requirement and recovery indices of mivacurium during either desflurane or isoflurane-based anesthesia. Patients who took longer to recover from the bolus dose in both groups showed a subsequent reduction in dose requirements of mivacurium.

Randomized Controlled Trial Clinical Trial
Oxygen administration during transport and recovery after outpatient surgery does not prevent episodic arterial desaturation.
To compare the efficacy of two different oxygen (O2) delivery systems in preventing episodic arterial desaturation in the immediate postoperative period. ⋯ Routine O2 administration during transport and PACU stay did not abolish episodic desaturation, even in healthy patients undergoing minor surgical procedures. Given the marked difference in acquisition cost, it would appear that O2 administration by nasal cannula is a more cost-effective alternative for routine postoperative O2 administration in certain groups of patients undergoing general anesthesia for outpatient surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol infusion for induction and maintenance of anesthesia in elderly patients: recovery and hemodynamic profiles.
To evaluate the effect of propofol infusion for both induction and maintenance of anesthesia on hemodynamics and recovery in elderly patients compared with conventional thiopental-isoflurane anesthesia. ⋯ Induction of anesthesia by propofol infusion in elderly patients produces greater attenuation of cardiovascular sympathetic response than thiopental bolus induction. Induction and maintenance of anesthesia by propofol infusion results in more rapid recovery in our elderly patients than thiopental isoflurane anesthesia.
