Background: Ketorolac is an effective analgesic but the potential for acute kidney injury (AKI) is concerning, particularly in geriatric "G-60 trauma" patients. The objectives of this study are to report the incidence of AKI in patients who receive ketorolac, identify risk factors for AKI, and develop a risk factor-guided algorithm for safe utilization.
Methods: This retrospective cohort study included trauma patients age 60 years and older who received intravenous ketorolac. The primary endpoint was the incidence of AKI.
Results: Among 316 patients evaluated, the incidence of AKI was 2.5%. Patients with AKI received more nephrotoxins, had more comorbidities, and higher use of loop diuretics or vasopressors. Loop diuretic therapy and number of comorbidities were independent predictors of AKI.
Conclusions: Risk for AKI with ketorolac was low, being more prevalent with comorbidities or receipt of loop diuretics.
