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.

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).

Paravertebral nerve block has been used for a variety of surgical procedures to provide unilateral anesthesia and postoperative analgesia. We report the successful application of this regional anesthesia modality for outpatient lithotripsy. ⋯ The second patient underwent extracorporeal shock wave lithotripsy with propofol intravenous sedation. Postoperatively, both patients reported pain scores of zero (Visual Analog Scale) for 24 hours and required no opioid rescue analgesia.

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.
