Abstract :

Background: A complication of cardiac surgery, the sternal wound infection (SWI) rate in our organization has risen in three years to twice the state benchmark. The internal mammary arteries are routinely used in our institution for its long-term patient survival benefit, which can increase SWI risk. The biochemical effect of stress hyperglycemia in critically ill patients is a contributing factor to the development of infection. Glycemic control reduces infection risk by avoiding the body’s metabolic syndrome. The purpose of this study was to determine if there is a difference in glycemic index, graft choice, BMI and diabetes in cardiac surgery patients who have developed SWI and those who did not.

Methodology: Our longitudinal study was a retrospective medical record review conducted in an academic medical center. 130 cardiac surgery patients developing a SWI were matched with 130 patients who did not. Regression analysis compared differences in glycemic index, graft choice, BMI, and diabetes.

Results: The majority of the sample were male (61%) white (62%), and obese (52%); 76% underwent a coronary artery bypass graft procedure. Patients were 2.8 times more likely to develop a SWI (p <.001) when their mean blood glucose on the day of surgery was above160 mg/dl. Mean blood glucose on post-operative day #1 (p =.70) and #2 (p =1.00) were not significant. No differences were found in the relationship of graft choice and SWI (p =.61). Females were two times more likely to develop a SWI than males (p = .02). 72% of the sample with a BMI of 30 and above developed a SWI (p =<.001). There was no difference (p =.19) in the relationship of history of diabetes and SWI.

Conclusion: I Improved blood glucose management targeting a mean blood glucose below 160 mg/dl on the day of surgery may help prevent SWI.
