Controlled Clinical Trial
The importance of blood sampling site for determination of hemoglobin and biochemistry values in major abdominal and orthopedic surgery.
To determine whether sampling of blood from different sites influences laboratory results. ⋯ Under stable hemodynamics and in the absence of hypothermia, serum lactate level was higher in peripheral venous blood than it was in the central vein or radial artery.

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.

Randomized Controlled Trial
Pain prevention with intraoperative ketamine in outpatient children undergoing tonsillectomy or tonsillectomy and adenotomy.
To evaluate the effectiveness of ketamine in the prevention of postoperative pain after tonsillectomy. ⋯ Ketamine decreases postoperative analgesic requirements and has analgesic effects when used before surgery in tonsillectomy/adenotonsillectomy.

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.
