NCT06951308 | Recruiting

Brief Summary

Enhanced recovery after surgery protocols aim to optimize perioperative care and improve surgical outcomes. Preoperative carbohydrate loading has demonstrated benefits in reducing insulin resistance and improving patient outcomes. While non-diabetic patients benefit from this approach, its efficacy in diabetic type 2 patients undergoing CABG remains less understood. This study aims to address this gab by evaluating the physiological and clinical outcomes for carbohydrate loading in this specific population.

Conditions

Heart Surgery; Ischemic Heart Disease

Keywords

Enhanced recovery program; carbohydrate loading; coronary artery bypass grafting; heart surgery; postoperative recovery
