Randomized Controlled Trial Clinical Trial
Intraocular pressure and hemodynamic changes following tracheal intubation in children.
To determine the optimal time in which to make intraocular pressure (IOP) measurements in children following tracheal intubation. ⋯ We recommend that IOP be measured only after HR and MAP have returned to preintubation levels in children who have undergone tracheal intubation during halothane and N2O anesthesia.

Comparative Study
In vitro comparison of central venous catheters for aspiration of venous air embolism: effect of catheter type, catheter tip position, and cardiac inclination.
To test the relative efficiency of balloon-tipped and plain catheters for aspiration of venous air embolism. ⋯ This study demonstrated that efficacy of air recovery depends on catheter type, catheter tip position, and cardiac inclination. No benefit was derived from positioning the catheter tip inside the atrium or from using balloon-tipped catheters.

Randomized Controlled Trial Comparative Study Clinical Trial
Low-dose droperidol versus standard-dose droperidol for prevention of postoperative vomiting after pediatric strabismus surgery.
To determine whether a low dose of droperidol is as effective as a high dose in preventing vomiting after pediatric strabismus surgery. ⋯ Droperidol 20 microgram/kg is as effective as droperidol 75 microgram/kg in preventing vomiting after pediatric strabismus surgery. Because higher doses of droperidol may sedate some patients, the lowest effective dose should be used. In this study, however, there was no statistically significant difference with regard to length of recovery room stay.

Randomized Controlled Trial Clinical Trial
Effect of alfentanil on hypnotic and antinociceptive components of thiopental sodium anesthesia.
To determine the effects of alfentanil on the hypnotic and antinociceptive components of thiopental sodium anesthesia. ⋯ Alfentanil strengthened both the hypnotic and antinociceptive components of thiopental anesthesia, although to a different degree: the antinociceptive component more so than the hypnotic, possibly because each component of anesthesia has different underlying mechanisms.

Randomized Controlled Trial Comparative Study Clinical Trial
Phenylephrine in the prevention of hypotension following spinal anesthesia for cesarean delivery.
Phenylephrine and ephedrine were compared in the prevention of maternal hypotension following spinal anesthesia for elective cesarean delivery. ⋯ Phenylephrine is as effective as ephedrine in the treatment of maternal hypotension, and when used in small incremental bolus injections, it appears to have no adverse neonatal effects in healthy, nonlaboring parturients.
