Randomized Controlled Trial Comparative Study Clinical Trial
Hemodynamic effects during induction, laryngoscopy, and intubation with eltanolone (5 beta-pregnanolone) or propofol. A study in ASA I and II patients.
To evaluate the cardiovascular changes following induction of anesthesia, laryngoscopy, and intubation in patients receiving a bolus dose of either eltanolone or propofol. ⋯ Patients receiving either eltanolone or propofol showed similar cardiovascular changes to induction of anesthesia, although there were greater increases in arterial pressure and HR in those patients receiving eltanolone.

Randomized Controlled Trial Comparative Study Clinical Trial
Antiemetic efficacy of a droperidol-morphine combination in patient-controlled analgesia.
To evaluate the antiemetic effectiveness and side effects of adding low-dose droperidol to morphine delivered via a patient-controlled analgesia (PCA) device. ⋯ An intermittent intake of low-dose droperidol with morphine given via a PCA delivery system in two treatment groups gave evidence for a dose-response relation between the amount of droperidol added and the proportion of patients needing a rescue antiemetic. The same result applied to the proportion of patients having an emetic episode and the number of times a rescue antiemetic had to be administered. There was no evidence that the low dose of droperidol added to morphine delivered via a PCA device increased unwanted side effects.

Laryngeal mask airway: a more successful method of insertion.
To compare the ease of insertion of the laryngeal mask airway (LMA) by two methods. ⋯ Inserting the LMA with the cuff partially inflated is likely to be more successful than with the cuff fully deflated. When it is not possible to insert the LMA with the cuff fully deflated, partial inflation before insertion may result in correct placement.

Randomized Controlled Trial Comparative Study Clinical Trial
Study of the optimal duration of preoxygenation in children.
To determine the optimal length of preoxygenation in children. ⋯ 2 minutes of preoxygenation in children can provide the maximum benefit of denitrogenation and achieve 2 minutes of safe apea. 95% and 99% confidence intervals were 69 to 100 and 59 to 100, respectively. Succinylcholine had only a slight effect on the safe apneic period.

Randomized Controlled Trial Clinical Trial
Alfentanil suppresses coughing and agitation during emergence from isoflurane anesthesia.
To evaluate the effectiveness of alfentanil in suppressing coughing and agitation during emergence from isoflurane anesthesia. ⋯ Alfentanil decreased coughing, agitation, and cardiovascular stimulation during emergence from isoflurane anesthesia without prolonging the time of extubation.
