Abstract Background The association between nonsteroidal anti-inflammatory drugs (NSAIDs) and postoperative acute kidney injury (AKI) remains controversial, with limited studies specifically examining flurbiprofen. Therefore, this research aimed to investigate the association between intraoperative flurbiprofen administration and postoperative AKI. Methods We retrospectively identified a cohort of patients at the Third Xiangya Hospital of Central South University. A total of 3882 adult patients undergoing spinal surgery between January 1, 2012, and July 31, 2018, were included and classified into two groups: those receiving flurbiprofen (50 or 100 mg once, 5 min after anesthesia start) and those not receiving flurbiprofen. The primary endpoint was the incidence of AKI. Result The flurbiprofen group (4.4%) had a lower incidence of AKI compared to the non-flurbiprofen group (6.5%, P < 0.001). After adjusting for potential confounding variables, the multivariable regression analysis showed that the flurbiprofen group had a 49% reduced risk of postoperative AKI (OR 0.51; 95% CI 0.31 to 0.82) compared to the non-flurbiprofen group. Subgroup analysis indicated that flurbiprofen injection was associated with a reduced incidence of postoperative AKI in patients without diabetes (OR 0.61; 95% CI 0.19 to 0.74), surgical times of 2–5 h (OR 0.54; 95% CI 0.23 to 0.75), and preoperative anemia (OR 0.57; 95% CI 0.21 to 0.74). Conclusion The study concluded that perioperative flurbiprofen treatment was associated with a lower risk of postoperative AKI in adult patients undergoing spinal surgery.
