Randomized Controlled Trial
Effect of low tidal volume ventilation on atelectasis in patients during general anesthesia: a computed tomographic scan.
To determine whether low tidal ventilation in patients without lung injury results in an increase in the amount of atelectasis and a further impairment of gas exchange during general anesthesia. ⋯ Ventilation using low V(T)s does not cause more pulmonary collapse than mechanical ventilation using standard V(T)s.

Controlled Clinical Trial
No change in serum melatonin, or plasma beta-endorphin levels after sevoflurane anesthesia.
To investigate the effect of sevoflurane as single anesthetic on melatonin and beta-endorphin plasma levels during the first 24 hours postoperatively. ⋯ Sevoflurane as a single anesthetic for minor gynecological procedures did not influence significantly melatonin or beta-endorphin plasma levels. Sleep quality assessed clinically was not influenced.

Clinical Trial
Preoperative identification of sleep apnea risk in elective surgical patients, using the Berlin questionnaire.
To examine the prevalence of risk of sleep apnea in patients undergoing elective surgery by using the Berlin Questionnaire. ⋯ The Berlin questionnaire correctly identified all patients previously diagnosed with sleep apnea as being at high risk.

Randomized Controlled Trial
Muscle relaxation does not influence venous oxygen saturation during cardiopulmonary bypass.
To examine whether the omission of neuromuscular blocking drugs during cardiopulmonary bypass (CPB) is associated with increased anesthetic requirements, higher frequency of intraoperative movements, and lower venous oxygen saturation (SvO(2)). ⋯ Omitting the continuous administration of neuromuscular blocking drugs during CPB did not increase anesthetic requirements. No intraoperative movements occurred, nor was there decreased SvO(2).

Randomized Controlled Trial Comparative Study
Clinical comparisons between GlideScope video laryngoscope and Trachlight in simulated cervical spine instability.
To compare the time taken for tracheal intubation, hemodynamic changes, and perioperative morbidities between the GlideScope (GS) video laryngoscope and the Trachlight (TL) with manual inline stabilization. ⋯ Trachlight offers a faster intubation and a milder hemodynamic response than GS.
