Acute kidney injury (AKI) is a major complication of significant burn injuries and a significant cause of patient morbidity and mortality. Patients that sustain traumatic burn injuries may require computed tomography (CT) imaging as part of their initial trauma management. This multicenter retrospective chart review of patients admitted to two level I trauma centers with ≥10% TBSA burns between 2014 and 2017 aims to determine if patients with greater than 10% TBSA burns that received CT imaging with intravenous contrast were more likely to develop acute kidney injury during their admission. A total of 439 patients were included in the study. The average age was 45.3 years and average TBSA was 23.2%. Sixty-seven of the 439 patients underwent CT scans with IV contrast on admission. The rate of AKI between patients who did or did not receive CT scans was not statistically significant (9.1 vs 6.0%, P = 0.40). Patients who developed an AKI had higher TBSA (45.6 vs 21.1%, P < .01), amount of fluids per TBSA given within the first 24 hours (457.4 vs 321.6, P < .01), and mortality (71.1 vs 6.2%, P < .01) than those who did not develop an AKI. There was no significant difference in the development of acute kidney injury in burn patients who received CT scans with IV contrast on admission. Although there is a risk of contrast induced nephropathy, the risk is not increased in burn patients and this should not prevent a thorough evaluation to rule out additional life-threatening injuries in the burn trauma patient.
