Abstract

The effects of pulsatile cardiopulmonary bypass (CPB) systems and deep hypothermic circulatory arrest (DHCA) on global and regional cerebral blood flow (CBF) in a neonatal piglet model were determined. The experimental group results were: group I with aortic dp/dt of 487±76, pulse pressure of 36±7, and ejection time of 215±5; group II with aortic dp/dt of 135±17, pulse pressure of 19±3, and ejection time of 269±28; and group III with aortic dp/dt of 571±81, pulse pressure of 36±6, and ejection time 210±14. Groups I and III produced better pulsatile flow compared to group II. Although better global and CBF were observed in group II, standard deviations were also unusually high.
