RESUMEN
Background: Glycemic control in burn patients is critical for reducing infection and mortality. Objective: This study was conducted to assess the incidence and outcomes of hypoglycemia during continuous insulin infusions (CII). Methods: This institutional review board-approved study was a retrospective, single burn center, electronic chart review. Patients admitted between January 1, 2013, and October 31, 2014, who received a CII were included. Patients with incomplete data or who received <24 hours of CII were excluded. Results: Thirty-eight patients met inclusion criteria; 6 were excluded. The average patient was a 52-year-old Caucasian male with a 33% total body surface area burn and an acute physiology and chronic health evaluation (APACHE) II score of 20.Hypoglycemia was present for 87 of 6540 hours of CII therapy (1.1%). Two-thirds experienced a serum glucose <70 mg/dL and half <60 mg/dL. The most commonly assessed reasons for the hypoglycemic episodes were protocol violations (47%) and glucose variability (30%). After multivariable logistic regression, only history of diabetes remained a statistically significant risk factor with an odds ratio of 15.4 (95% confidence interval: 2.5-95.1). Four different CII protocols were prescribed. All protocols had a high glucose variability, as assessed by hours / day within goal range (13.1 ± 2.5, 14.1 ± 3.1, 14.3 ± 2.4, 9.8; P = .282). Conclusion: The amount of different protocols likely contributed to protocol violations and glucose variability. Our data demonstrate the need to create and consolidate usage to a single protocol in attempts to improve glycemic control.
