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
Removal of the laryngeal mask airway in children: deep anesthesia versus awake.
To compare the incidence of adverse airway events identified with removal of the laryngeal mask airway (LMA) from an awake child or from a child before his or her airway reflexes had returned. ⋯ Removal of the LMA during anesthesia and after return of airway reflexes results in a similar incidence of airway problems in children.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of epidural morphine and oxycodone for pain after abdominal surgery.
To compare the efficacy and side effects of epidural morphine and oxycodone for pain following major abdominal surgery. ⋯ In the dosages reported, oxycodone can be used epidurally for acute post-operative pain. The analgesic effect was as good as that of epidural morphine.

Randomized Controlled Trial Comparative Study Clinical Trial
Laryngo-pharyngeal complaints following laryngeal mask airway and endotracheal intubation.
To investigate the incidence and severity of laryngo-pharyngeal complaints following anesthesia with the use of a laryngeal mask airway (LMA) compared with endotracheal intubation in adults. ⋯ There is a distinct pattern of laryngo-pharyngeal complaints following the use of the LMA and endotracheal intubation. With regard to minor laryngo-pharyngeal morbidity, the advantage of the LMA to endotracheal intubation is questionable.
