Anesthetic induction with ketamine inhibits platelet activation before, during, and after cardiopulmonary bypass in baboons.

The objective of this study was to investigate the effects of antifactor D monoclonal antibody (Mab) 166-32 on platelet activation during and after hypothermic cardiopulmonary bypass (CPB) in baboons. Fourteen baboons (mean weight, 15 kg) underwent hypothermic CPB. Seven of them were treated with a single injection of antifactor D Mab 166-32 (5 mg/kg) and the other seven animals were given saline as control.

Use of near-infrared spectroscopy to monitor regional cerebral oxygen saturation during infrarenal aortic crossclamping in piglets.

Purpose: The hemodynamic changes induced by infrarenal aortic crossclamping have been well documented, but the effects of such crossclamping on cerebral perfusion are unknown. To investigate these effects, we used near-infrared spectroscopy (NIRS) to monitor regional cerebral oxygen saturation (rSO2) during infrarenal aortic crossclamping in a piglet model.

Methods: The study involved 19 piglets, each weighing 7.

BioGlue surgical adhesive impairs aortic growth and causes anastomotic strictures.

Background: BioGlue surgical adhesive (CryoLife, Inc, Kennesaw, GA) is currently being used to secure hemostasis at cardiovascular anastomoses in adults. Interference with vessel growth would preclude its use during congenital heart surgery. The purpose of this study was to determine if BioGlue reinforcement of aortic anastomoses impairs vessel growth and causes strictures.
