    ObjectiveIntravenous glyburide has demonstrated safety when used for attenuation of cerebral edema, although safety data are lacking for enteral glyburide when used for this indication. We aimed to determine the prevalence of and risk factors for hypoglycemia in neurocritical care patients receiving enteral glyburide.MethodsWe performed a retrospective case-control chart review (hypoglycemia vs. no hypoglycemia) of adult patients who received enteral glyburide for prevention or treatment of cerebral or spinal cord edema. Hypoglycemia was defined as a blood glucose <55.8 mg/dL. Descriptive statistics were used, with multivariate analysis to measure the association of risk factors and outcomes. Logistic regression was applied to outcomes with an exposure. Potential confounders were evaluated using the t-test or the Wilcoxon rank-sum test for continuous variables, and the χ2 test or the Fisher exact test for categorical variables.ResultsSeventy-one patients (60.6% men, median age 60 years) were included. The majority received 2.5 mg of enteral glyburide twice daily. Diagnoses included tumors (35.2%), intracerebral hemorrhage (28.2%), postspinal surgery (12.7%), and ischemic stroke (12.7%). Hypoglycemia occurred in 17 (23.9%) patients. Multivariate analysis identified admission serum creatinine (odds ratio, 27.2; [1.661, 445.3]; P < 0.05) as a risk factor for hypoglycemia, whereas body mass index >30 (odds ratio, 0.085; [0.008, 0.921]; P < 0.05) was protective.ConclusionsHypoglycemic episodes are common following enteral glyburide in neurocritical care patients. Both patients with and without diabetes mellitus are at risk of hypoglycemia. Elevated admission serum creatinine may increase the risk of hypoglycemia when utilizing glyburide for prevention or treatment of cerebral or spinal cord edema.Copyright © 2020 Elsevier Inc.
