Effect of Tight Glycemic Control Protocol on Hypoglycemia and Mortality in the Burn Unit: A Case-Control Study

Summary

Background:

Burn injury pathophysiology is characterized by severe catabolic state and poor glycemic control. A tight glycemic control protocol using insulin for burn victims has yielded inconsistent mortality and morbidity outcomes.

Objectives:

To compare the effect of standard and tight glycemic control protocols on mortality and hypoglycemia events in critical care burn patients.

Methods:

We conducted a case-control study of burn victims admitted to the burn intensive care unit between 2005 and 2011. Patients were assigned to either a standard or a tight glycemic control protocol.

Results:

Of the 38 burn patients in the study, 28 were under a tight glycemic control protocol. No differences in glucose area-under-the-curve per day levels were observed between the groups (148.3 ± 16 vs. 157.8 ± 16 mg/dl in the standard and tight glycemic control protocol groups respectively, P < 0.12). The hypoglycemic event rate was higher in the tight glycemic control protocol group (46.4% vs. 0%, P < 0.008). No difference in mortality rate was noted (67.9% vs. 50%, P < 0.31). Mortality-independent risk factors found on multivariate analysis included total body surface area (adjusted hazard ratio [AHR] 1.039, 95% confidence interval  [95%CI] 1.02–1.06, P < 0.001), white blood cell count on admission (AHR 1.048, 95%CI 1.01–1.09, P < 0.02) and surgery during hospitalization (AHR 0.348, 95%CI 0.13–0.09, P < 0.03).

Conclusions:

The tight glycemic control protocol in burn patients was associated with higher rates of hypoglycemic events, and no association was found with improved survival in the acute setting of burn trauma care.
