Intraoperative Changes in Blood Glucose Levels Increase the Risk of Death in Cardiac Surgery

Introduction: Hyperglycemia and insulin resistance is common in postoperative and critically ill patients, and increases the risk of death and adverse outcome. Keeping glucose levels from rising much higher than the upper normal range has shown to improve outcome in a postoperative setting. The perioperative impact of variations in glucose levels remains to bee seen. Therefore the aim of this study is to determine whether intraoperative changes in blood glucose levels have an impact on the survival of cardiac surgical patients. Methods: We reviewed the medical records of 3695 cardiac surgery patients between Dec…
