Do mask aperture bars of extraglottic airway devices prevent prolapse of epiglottis causing airway obstruction? A randomized crossover trial in anesthetized adult patients.

Study Objective: The study objective is to determine whether extraglottic airway devices (EADs) with or without mask aperture bars (MABs) result in similar anatomical positions in patients undergoing surgery.

Design: Prospective, randomized, crossover comparison of four extraglottic airway devices.

Setting: Operating theatre at a large teaching hospital.

Resistive-heating or forced-air warming for the prevention of redistribution hypothermia.

Background: We evaluated the efficacy of resistive-heating or forced-air warming versus no prewarming, applied before induction of anesthesia for prevention of hypothermia.

Methods: Twenty-seven patients scheduled for laparoscopic colorectal surgery were randomized into 1 of 3 groups: no prewarming; 30 minutes of prewarming with a carbon fiber total body cover at 42 degrees C; or 30 minutes of preoperative forced-air warming at 42 degrees C. The forced-air warming cover excluded the shoulders, ankles, and feet.

Preoperative alprazolam reduces anxiety in ambulatory surgery patients: a comparison with oral midazolam.

Unlabelled: Because an oral formulation of midazolam is not approved in certain countries, we evaluated oral alprazolam as an alternative. Forty-five outpatients scheduled for gynecological laparoscopic surgery participated in a double-blinded study to compare the effectiveness and side effects of oral alprazolam 0.5 mg with midazolam 7.
