OBJECTIVES: To investigate the effects of postoperative intensive glycemic control on patient outcomes. BACKGROUND: Ineffective perioperative glycemic control has been associated with high mortality and morbidity rates among cardiac surgery patients. METHODS:212 cardiac surgery patients were allocated by a quasi-experimental design to: a) a control group (n = 107) with targeted blood glucose levels 161-200 mg/dl or b) a therapy group (n = 105) with blood glucose target 120-160 mg/dl. We compared the two groups on their mortality, length of stay, duration of intubation, incidence of severe hypoglycemia and frequency of postoperative infections. RESULTS: The mean postoperative blood glucose levels were significantly lower for the therapy group compared with the control group (153.9 mg/dl vs. 173.9 md/dl, p < 0.001). The intensive glycemic control was strongly associated with decreased in-hospital mortality (7 deaths/105 patients for the control group vs. 1 death/105 patients for the therapy group; p = 0.033). We did not identify any statistically significant associations regarding the other patient outcomes. CONCLUSIONS: This randomized quasi-experimental trial found lower in-hospital mortality with more intense blood glucose control. Effective postoperative glycemic control did not affect the other studied patient outcomes.
