Since older subjects have a higher risk of acute renal failure, we have extended our study to evaluate the specific impact of pulsatile CPB on the perioperative renal function in elderly patients.
Baseline rScO 2, as measured by the INVOS 5100, decreases with advanced age and is lower in women. New definitions of cerebral oxygen desaturation need to be analyzed in future trials that will evaluate neurologic outcome in the aging population or in women.
