To evaluate the effect of steroid administration on myocardial infarction (MI), stroke, renal insufficiency, death, intensive care (ICU) length of stay (LOS) and hospital LOS of patients undergoing cardiopulmonary bypass (CPB). ⋯ Increasing the duration of steroid administration may reduce ICU and hospital LOS greater than increasing the dose.

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).

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.

Evidence supports the concept that patients undergoing major orthopedic surgery benefit from either thromboprophylaxis or peripheral nerve blocks, especially continuous techniques. A group of anesthesiologists with significant experience in orthopedic anesthesia and peripheral nerve blocks reviewed the literature related to thromboprophylaxis and peripheral nerve blocks and their combination in orthopedics. Major bleeding, including retroperitoneal hematoma, is an established complication of thromboprophylaxis. ⋯ Between 1997 and 2012, only 4 case reports of major bleeding were reported in patients receiving thromboprophylaxis and peripheral nerve blocks. Evidence supports the safety of the combination of thromboprophylaxis and peripheral nerve blocks. This group of experts concluded that currently there is no evidence that the combination of thromboprophylaxis and peripheral nerve block increases the risk of major bleeding compared to either of the treatments alone.
