Controlled post-operative blood glucose levels

What It Means
Percentage of patients with a blood glucose of <200 mg/dL at 6 a.m. on postoperative day 1 and day 2. (The day of surgery is day 0)

Why It Is Important
High blood sugar can increase the risk of infection for surgical patients, especially patients undergoing coronary artery bypass graft (CABG).
