Immediate Postoperative Evolution of Cerebral Doppler and Saturation Parameters After Cardiopulmonary Bypass in Infants With Congenital Heart Disease: A Prospective Cohort Study.

ABSTRACT:

Objectives

To describe temporal trends and instantaneous relationships between middle cerebral artery (MCA) cerebral blood flow velocity, cerebral oxygen saturation (Csat), cerebral fractional tissue oxygen extraction (cFTOE), and systemic arteriovenous oxygen difference (AVo2) during the first 24 hours following congenital heart disease (CHD) surgery requiring cardiopulmonary bypass (CPB).

Design

Prospective observational study conducted from August 2021 to June 2022.

Setting

Single-center pediatric cardiac ICU in Canada.

Patients

Fifteen ventilated neonates and infants admitted to the PICU following CHD surgery requiring CPB.

Interventions

None.

Measurements and main results

Bilateral transcranial Doppler (TCD) assessments of the MCA were perfor
