Continuing renin-angiotensin-aldosterone system antagonist therapy on the day of surgery is controversial, and appears to contribute to intraoperative hypotension. A patient presenting for cerebral aneurysm clipping continued her angiotensin-converting enzyme inhibitor on the morning of surgery, and subsequently experienced significant postinduction hypotension that culminated in cardiac arrest. Following successful resuscitation, she returned 6 weeks later to have her aneurysm clipped using identical anesthetic management; her blood pressure medications were held on the day of surgery.

To evaluate intraperitoneal ropivacaine delivery with the AeroSurge device in the clinical setting and to evaluate the total systemic ropivacaine levels achieved following delivery of 50 mg of aerosolized ropivacaine. ⋯ This preliminary study confirms that aerosolized intraperitoneal local anesthetic is feasible, with ropivacaine concentrations remaining within safe levels.

To determine, for two different age groups, the effect of duration of sevoflurane administration on the amount of propofol needed when performing tracheal intubation. ⋯ The amount of propofol needed to supplement sevoflurane in children 1-6 years of age can be expected to decrease after 4 minutes of sevoflurane.
