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.

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.

Case Reports
Acute hemodynamic effects of indigo carmine in the presence of compromised cardiac function.
This report describes the acute hemodynamic effects of indigo carmine in a surgical patient with compromised cardiac function. A 68-year-old woman with stable but severe cardiac dysfunction and renal artery stenosis was scheduled for an elective aortorenal bypass procedure. ⋯ At that time, the patient experienced an acute increase in afterload, which resulted in acute left ventricular failure documented by a decrease in cardiac output (CO) and an increase in pulmonary artery pressure (PAP). Until further studies defining the mechanism for its hypertensive side effect are performed, indigo carmine should be used with caution in patients with severe cardiac dysfunction.
