Popis: AbstractBackground This retrospective study aimed to determine the incidence, risk factors, and outcomes of acute kidney injury (AKI) in neonates following the arterial switch operation (ASO) for transposition of great arteries (TGA).Methods Retrospective review of medical data of children who underwent ASO in 2019–2020 in the Ukrainian Children’s Cardiac Center.Results 76 consecutive neonatal patients were included, 48 developed AKI after ASO (51.7%), and 24 – had severe AKI (25.8%). Severe AKI development was associated with longer cross-clamp time: 82 (61–127) versus 73.5 (53–136) in the non-severe AKI group (p = 0.02). 76 min of cross-clamp time were defined as a threshold value for increased severe AKI risk, OR 4.4 (95% CI: 1.5 – 13, p = 0.01). Higher lactate levels during cardiopulmonary bypass (CPB) increased severe AKI development risk, OR 1.5 (95% CI: 1.0 − 2.0, p = 0.03). Children with severe AKI had prolonged mechanical ventilation, longer time to negative fluid balance, and higher postoperative day 3 (POD3) Inotropic Score (IS). Only one patient required peritoneal dialysis.Conclusions In our study, 51.7% of patients developed AKI after ASO, 25.8%–severe AKI. Prolonged cross-clamp time and higher lactate levels during cardiopulmonary bypass increased the risk for severe AKI development. The development of AKI was associated with prolonged mechanical ventilation, longer time to negative fluid balance, higher POD 3 Inotropic Score.
