Randomized Controlled Trial Clinical Trial
Effect of propofol for induction and ondansetron with or without dexamethasone for the prevention of nausea and vomiting after major gynecologic surgery.
To test the hypothesis that for major gynecologic surgery the combination of propofol for induction, ondansetron, and dexamethasone would be a more effective antiemetic combination than propofol for induction, ondansetron, and saline; and to determine if a propofol induction of anesthesia improved our previously reported results when thiamylal was the induction drug. ⋯ The hypothesis that the addition of dexamethasone to the propofolondansetron combination would significantly reduce postoperative nausea and vomiting (PONV) was not confirmed. A propofol induction of anesthesia resulted in a comparable incidence of PONV when compared with our previously reported results using thiamylal for induction of anesthesia for women having major gynecologic operations.

Clinical Trial
Heart rate, heart rate variability, and blood pressure during perioperative stressor events in abdominal surgery.
To define the behavior of power spectral heart rate variability (PSHR) during potentially stressful events in the perioperative period, and relate it to changes in blood pressure (BP) and heart rate (HR). ⋯ On anesthetic induction, preoperative, but not intraoperative, spectral indices were predictive of BP changes. Power spectral analysis of HR may provide information about the autonomic state that is not evident from BP or HR. The HR power spectrum, in particular, indicated a striking autonomic imbalance immediately after the induction of anesthesia despite stable HR and BP. LFA and LFA/RFA ratio appeared to track sympathetic autonomic activation during abdominal surgical stimulation, but not during other perioperative stressor events.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison: the efficacy of sevoflurane-nitrous oxide or propofol-nitrous oxide for the induction and maintenance of general anesthesia.
To compare sevoflurane-nitrous oxide with propofol-nitrous oxide for the induction and maintenance of anesthesia, and to determine the rates of recovery following each anesthetic. ⋯ Sevoflurane allows for rapid inhalation induction of, and emergence from, general anesthesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative analgesia and intraoperative inhalational anesthetic requirements during umbilical herniorrhaphy in children: postincisional local infiltration versus preincisional caudal epidural block.
To determine the postoperative analgesic efficacy of, and the effects on, intraoperative inhalational anesthetic requirements of preincisional caudal epidural block versus postincisional infiltration of local anesthetic following umbilical herniorrhaphy in children. ⋯ Preincisional caudal epidural block is more effective in controlling pain following umbilical herniorrhaphy than is postincisional local infiltration.
