Differences Between Central Venous and Cerebral Tissue Oxygen Saturation in Anaesthetised Patients With Diabetes Mellitus.

ABSTRACT: The brain has high oxygen extraction, thus the regional cerebral tissue oxygen saturation (rSO₂) is lower than the central venous oxygen saturation (ScvO₂). We hypothesised that diabetes widens the physiological saturation gap between ScvO₂ and rSO₂ (gSO₂), and the width of this gap may vary during various phases of cardiac surgery. Cardiac surgery patients with (n = 48) and without (n = 91) type 2 diabetes mellitus (T2DM) underwent either off-pump coronary artery bypass (OPCAB) or other cardiac surgery necessitating cardiopulmonary bypass (CPB) were enrolled. rSO₂ was measured by near-infrared spectroscopy (NIRS) and ScvO₂ was determined simultaneously from central venous blood. rSO₂ was registered bef
