Does Preoperative Glycosylated haemoglobin levels predict perioperative outcomes in patients undergoing on pump CABG surgery.

Abstract :

Diabetes mellitus is one of the major risk factors for ischemic heart disease & atherosclerosis. It is a systemic disease involving all the systems of the body. Various studies have shown uncontrolled diabetes to be associated with many macro vascular complications like coronary artery disease, stroke & micro vascular complications like nephropathy, neuropathy, retinopathy, etc. Studies has also shown that glycosylated haemoglobin (HbA1C) level is an indicator of blood sugar control over the last 3–4 months and it predicts both micro & macro vascular complications. The optimal control of blood sugar in the perioperative period during cardiac surgery is a very controversial topic and many studies have addressed it differently. Perioperative hyperglycemia is an independent risk factor for increased morbidity & mortality during cardiac surgery. The objective of this study is to find out whether long term preoperative blood glucose control as indicated by the HbA1C (blood sugar levels over last 3–4 months) level influence the perioperative blood sugar levels, insulin requirement, inotropic requirement, the incidence of atrial fiillation, infection rate & duration of ICU & hospital stay in patients undergoing on pump CABG surgery.
