Neurological impairment may occur following cardiopulmonary bypass (CPB)and the effect of CPB on cerebrovascular control may be important in themechanism of cerebral injury. We have used near infrared spectroscopy(NIRS) to observe cerebral haemodynamics non-invasively before and duringCPB. We measured the change in cerebral blood volume (CBV) associated withchanging PaCO2 (CBVR). Patients (n = 19) were aged from 1 to 135 (median14) months. The cerebral blood volume response was determinedpre-operatively at normothermia under the influence of standardisedanaesthesia employing isoflurane (up to ET conc 0.5%) and duringsteady-state hypothermic bypass (22-32 degrees C) at an arterial pump flowrate of 1.9-2.4 lm-2.min-1. Complete data was availa...
