Clinical Trial Controlled Clinical Trial
Efficient inspired concentration of sevoflurane for vital capacity rapid inhalation induction (VCRII) technique.
To evaluate the efficient inspired concentration of sevoflurane for a vital capacity rapid inhalation induction (VCRII) technique with respect to induction time, characteristics, and acceptability. ⋯ Sevoflurane 6% can be recommended for VCRII, but increasing the concentration higher than this does not markedly shorten the induction time and thus seems to add little benefit.

Randomized Controlled Trial Clinical Trial
The effect of cricoid pressure application on airway patency.
To assess the incidence of upper airway obstruction associated with the application of cricoid pressure (Sellick's maneuver) by experienced anesthetists. ⋯ The use of manual cricoid pressure, even by experienced anesthetists, causes a degree of airway obstruction and can cause complete airway occlusion.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of preincision versus postincision infiltration with bupivacaine on postoperative pain.
To compare the efficacy of preincision wound infiltration with bupivacaine to wound infiltration at the end of the operation. ⋯ Wound infiltration, either preincision or postincision, had no clinically significant effect on the pain scores or analgesic requirements following abdominal hysterectomy.

Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of guanfacine in reducing perioperative hemodynamic changes and volatile anesthetic requirement.
To evaluate the efficacy of guanfacine, an alpha 2-adrenergic agonist, for attenuating hemodynamic changes associated with tracheal intubation or extubation, providing intraoperative hemodynamic stability, and reducing inhalation anesthetic requirement in patients undergoing gynecologic surgery. ⋯ Guanfacine 1 mg administered orally proved to be an effective premedicant for providing intraoperative hemodynamic stability, attenuating the increase in BP and HR associated with tracheal intubation and extubation, and reducing anesthetic requirements without increasing the incidence of perioperative complications.
