Cerebral Autoregulation During Antegrade Cerebral Perfusion in Neonates Undergoing Congenital Cardiac Surgery.

Below the lower limit of autoregulation (lower limit of autoregulation), total hemoglobin and mean arterial blood pressure will positively correlate.

Cerebral autoregulation curves were constructed for each patient to determine the lower limit of autoregulation using an HVx cutoff of ≥0.2.

The median age was 5 days (interquartile range [IQR] 3, 9), antegrade cerebral perfusion time was 61 minutes (IQR 47, 77), and median lower limit of autoregulation was 37.3 mmHg (IQR 34.6, 41.1).
