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.

Approximately 40% of physician office time and 33% of hospital time are devoted to patients 65 years of age or older. Over half of the older population requires some surgical intervention. Because of decreased physiologic reserve and increased number of underlying medical disorders, the older patient is at increased risk for intraoperative and postsurgical complications. ⋯ Risk factors should be assessed initially by a focused history and physical examination and by simple tests. Additional diagnostic testing should be reserved for the patient who is not clearly at low or high risk. For optimal preoperative evaluation of the elderly patient, the physician should identify systemic disease, determine if the patient is receiving appropriate therapy, delineate the operative risks, and make recommendations that can potentially reduce the operative risks and postoperative complications.

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
Does 360 ml of apple juice ingested before elective surgery worsen gastric volume and acidity in patients given acid aspiration prophylaxis?
To evaluate whether 360 ml of oral clear liquids consumed within 4 hours of elective surgery worsens gastric volume and acidity in patients given acid aspiration prophylaxis. ⋯ Three hundred and sixty ml of apple juice consumed within 4 hours of elective surgery by patients given ranitidine and metoclopramide did not worsen gastric volume and acidity.
