Randomized Controlled Trial Clinical Trial
Preoperative clonidine attenuates stress response during emergence from anesthesia.
To investigate whether a single preoperative IV dose of clonidine blunts the hemodynamic and hyperadrenergic responses not only to intubation, but also to extubation. ⋯ A single preoperative IV dose of clonidine (3 microg/kg) blunts the hemodynamic responses due to extubation in noncardiac surgery of intermediate duration.

Randomized Controlled Trial Clinical Trial
Sevoflurane-N2O versus propofol/isoflurane-N2O during elective surgery using the laryngeal mask airway in adults.
To compare a sevoflurane-nitrous oxide (N2O) general anesthetic technique with a standard technique of propofol for induction, and isoflurane-N2O for maintenance. ⋯ Sevoflurane-N2O and propofol provided comparable conditions for LMA insertion. Sevoflurane-N2O was not associated with a faster return of consciousness or faster time to exit the OR compared with isoflurane-N2O.

Randomized Controlled Trial Comparative Study Clinical Trial
The influence of preemptive spinal anesthesia on postoperative pain.
To examine the influence of spinal anesthesia on postoperative pain and postoperative opioid requirements. ⋯ Preoperative neural blockade may reduce postoperative analgesic requirements.

To evaluate the efficacy of tropisetron, a selective 5-HT(3) receptor antagonist, in preventing nausea and vomiting in high-risk inpatients undergoing various surgical procedures. ⋯ Prophylactic tropisetron can reduce the incidence of PONV in selected high-risk inpatients undergoing various types of surgical procedures.

Case Reports Clinical Trial
Noninvasive ventilation using bilevel positive airway pressure to treat impending respiratory failure in the postanesthesia care unit.
The author presents the use of noninvasive positive pressure ventilation using bilevel positive airway pressure (BiPAP) to treat respiratory insufficiency and hypoxemia in three patients in the postanesthesia care unit. BiPAP improved respiratory function with a decreased respiratory rate, decreased PaCO2, and improved oxygenation in the three patients. The applications of these techniques and equipment required are reviewed.
