The brain has high oxygen extraction, thus the regional cerebral tissue oxygen saturation (rSO) is lower than the central venous oxygen saturation (ScvO). We hypothesised that diabetes widens the physiological saturation gap between ScvO and rSO (gSO), 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.

Since this disease needs lifelong treatment and care, the medical and social aspects present major public health concerns and pose a global challenge for health care providers. The number of aged patients with degenerative diseases undergoing surgical procedures is continuously increasing, resulting in an overwhelming dominance of diabetes in the perioperative care.
