Abstract

Objective: Perioperative poor glycemic control in diabetic patients undergoing Coronary Artery Bypass Graft (CABG) surgery has been associated with infectious complications, particularly surgical site infections that are linked with adverse health surgical outcomes. The purpose of this study was to investigate the effect of two different intraoperative glycemic control protocol, tight and conventional, on thirty-day postoperative surgical site infection (SSI) rates among diabetic patients undergoing CABG surgery.

Design: A randomized controlled trial (RCT) design was employed in the study, with a convenience sample of 144 adult patients who were scheduled to undergo coronary artery bypass grafting surgery.

Setting: A main referral heart institute in Amman, Jordan.

Participants: Subjects were randomly assigned to either the tight glycemic control group (n = 72), which maintained an intraoperative blood glucose level of 110-149 mg/dl via continuous intravenous insulin infusion, or the conventional glycemic control group (n = 72), which maintained an intraoperative blood glucose level of 150-180 mg/dl via continuous intravenous insulin infusion. The postoperative SSIs among both groups were evaluated and compared by independent blinded physicians.

Results: The primary findings of this study indicated no statistically significant difference between the two treatment groups in terms of SSI rates and their potential adverse surgical outcomes (p = 0.512).

Conclusion: Nurses should consider the glycemic stability and glycemic control approach to minimize adverse surgical outcomes post CABG surgery. Healthcare providers should also carefully consider diabetic patients who have undergone CABG surgery and are at risk of developing postoperative SSIs.
