High flow rates during modified ultrafiltration decrease cerebral blood flow velocity and venous oxygen saturation in infants.

Background: The intracranial hemodynamic effects of modified ultrafiltration in children are unknown. We investigated the effects of different blood flow rates during modified ultrafiltration on the cerebral hemodynamics of children with weights above and below 10 kg.

Methods: Thirty-one children (weights: < or = 10 kg, n = 21; > 10 kg, n = 10) undergoing cardiopulmonary bypass were studied.

At the turn of the millennium, perfusion teaching programs are faced with significant difficulties. The number of students in pediatric perfusion training has increased, and more importantly, the number of pediatric open-heart procedures has decreased because of a variety of reasons. Hence, they could barely satisfy the minimum requirements of pediatric cases established by the teaching programs.
