Objective: To compare the incidence and severity of acute kidney injury (AKI) after cardiac surgery with cardiopulmonary bypass and the administration of exogenous nitric oxide in children. Design: A retrospective cohort study. Setting: A single institution, university hospital. Participants: All children younger than 18 years of age who underwent surgery with cardiopulmonary bypass. Interventions: Medical records of all eligible patients between January 4, 2017, and June 28, 2019, were reviewed. Patients were divided into two groups based on whether they received exogenous nitric oxide. Measurements and Main Results: The primary endpoint was a change in serum creatinine level, defined as the difference between the preoperative creatinine and peak postoperative creatinine. The secondary endpoint was the incidence and severity of postoperative AKI. A difference-in-difference method using fixed-effect multiple linear regression was carried out to compare the difference in maximum serum creatinine changes between the control and intervention groups. Five hundred ninety-one patients were included in the analysis: 298 (50.5%) in the control group and 293 (49.5%) in the intervention group. Control and intervention groups did not vary significantly in terms of baseline characteristics except for bypass time. After adjusting for all baseline variables, there was no statistically significant difference in the increase in serum creatinine between the control and the intervention groups (0.01 [95% CI: –0.03, 0.05], p = 0.545). Conclusions: This single-center, retrospective, cohort study found no change in the incidence and severity of postoperative AKI after the administration of nitric oxide into the cardiopulmonary bypass circuit in children.
