OBJECTIVE: To analyze adrenal injuries using the National Trauma Data Bank (NTDB). Adrenal trauma is rare and current literature is lacking in data from large case series.
MATERIALS AND METHODS: A retrospective analysis of the NTDB from the years 2007-2011 was performed. Patient demographics, Injury Severity Score (ISS), mechanism of injury, type of trauma, associated injuries, and development of shock were assessed. Multivariable models were used to determine association with outcomes, such as characterization of injury, need for adrenalectomy, ICU admission, and death.
RESULTS: Of the 1,766,606 trauma cases recorded, 7791 involved one or both adrenal glands (0.44%). Common associated injuries were to the ribs (50.9%), thorax (50.0%), and liver (41.6%). Eighty adrenal injuries required surgery (80/7791, 1.0%), none of which were isolated adrenal injuries (0/120, p=0.63). Higher ISS (p=0.009), Black race (p=0.031), penetrating injury (p<0.001), and splenic (p<0.001) and intestinal injuries (p=0.018) were associated with need for adrenalectomy. No isolated adrenal injuries were associated with death (12% vs. 0%, p<0.0001). Older age (p<0.001), higher ISS (p<0.001), chronic kidney disease (p=0.009), penetrating injuries (p<0.001) and injuries to the aorta/vena cava (p=0.008), peripheral vasculature (p<0.0001), thorax (p=0.029), brain/spinal cord (p<0.001), and abdominal polytrauma (p=0.005) were associated with mortality.
CONCLUSIONS: Adrenal injuries are rare, comprising 0.44% of recorded traumatic injuries. Isolated adrenal injuries were not fatal and did not require surgery, thus should be managed conservatively. Detection of adrenal injury in polytrauma patients is key, particularly penetrating trauma and concurrent splenic/intestinal injuries, as these patients are more likely to require adrenalectomy.
