Randomized Controlled Trial
Inconsistency between simultaneous blood pressure measurements in the arm, forearm, and leg in anesthetized children.
To determine the accuracy and precision of simultaneous noninvasive blood pressure (NIBP) measurement in the arm, forearm, and ankle in anesthetized children. ⋯ Forearm and ankle NIBP measurements are unreliable and inconsistent with NIBP measured in the arm of anesthetized children. These alternative BP measurement sites are not reliable in accuracy (comparison with reference "gold" standard) and precision (reproducibility).

The effects of a small-dose ketamine-propofol combination on tourniquet-induced ischemia-reperfusion injury during arthroscopic knee surgery.
To determine the effects of a small-dose ketamine-propofol combination used for sedation during spinal anesthesia on tourniquet-induced ischemia-reperfusion injury. ⋯ Small-dose ketamine-propofol combination may be useful in reducing tourniquet-induced ischemia-reperfusion injury in arthroscopic knee surgery.

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.
