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.

To determine retrospectively the effect of high-dose opiate-oxygen (O2) anesthetic technique on intraoperative ventricular fibrillation in high-risk neonates. ⋯ High-dose opiate-O2 anesthesia in these patients markedly decreased intraoperative ventricular fibrillation. Other clinical reports and recent experimental work suggest that this finding is due to high-dose opiates rather than the avoidance of N2O.

To compare actual infectious disease precautions with current recommendations and to determine the influence of age, clinical experience, human immunodeficiency virus (HIV) knowledge, previous personal HIV exposure, and education on practices. ⋯ Adequate infectious disease precautions were not taken by anesthesia personnel. An HIV educational program resulted in only a small increase in precautionary measures.
