Are adrenal injuries predictive of adrenal insufficiency in patients sustaining blunt trauma?
Adrenal insufficiency (AI) is an uncommon life-threatening development in trauma patients. The aim of this study was to determine if adrenal injury sustained during blunt trauma is associated with an increased risk of AI. A single-institution retrospective cohort review was performed over a 3-year period on all patients with blunt trauma requiring intensive care admission and mechanical ventilation for longer than 24 hours. Adrenal injuries were identified on admission CT scan. All patients with AI were identified as noted by practice management guidelines. Patients were stratified by Injury Severity Score (ISS) as less than 16, 16 to 25, and greater than 25 and relative risks were calculated. Multiple logistic regression was performed using age, race, sex, Glasgow Coma Scale, ISS, length of hospitalization, and adrenal injury as covariates with AI as the outcome of interest. A secondary analysis was then performed with adrenal injury classified as bilateral versus unilateral or no adr
