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
Does monitoring end-tidal isoflurane concentration improve titration during general anesthesia?
To assess the value of end-tidal anesthetic gas monitoring with respect to intraoperative hemodynamic stability and recovery times. ⋯ This study suggests that end-tidal isoflurane monitoring does not improve the titration of isoflurane during general anesthesia.

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.

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
Study of the optimal duration of preoxygenation in children.
To determine the optimal length of preoxygenation in children. ⋯ 2 minutes of preoxygenation in children can provide the maximum benefit of denitrogenation and achieve 2 minutes of safe apea. 95% and 99% confidence intervals were 69 to 100 and 59 to 100, respectively. Succinylcholine had only a slight effect on the safe apneic period.
