The role of blood pressure versus oxygen administration on cerebral oxygenation during and after anaesthesia induction: A prospective cohort study.

ABSTRACT:

Background

The effect of anaesthesia induction on cerebral perfusion is complex due to the coinciding respiratory and haemodynamic changes that occur.

Objective

To examine how changes in blood pressure and oxygen administration are related to cerebral oxygenation and its progression over time during and after anaesthesia induction.

Design

Prospective observational study.

Setting

Dutch tertiary hospital from October 2019 to May 2022.

Patients

Two hundred and fifty-one elective cardiac surgery patients of which 188 were included in the analysis.

Main outcome measures

Continuous cerebral oxygenation, measured using near-infrared spectroscopy (NIRS)-based regional cerebral tissue oximetry, was assessed in relation to mean arterial pressure (MAP), part
