Abstract

Acute kidney injury (AKI) in children with Transposition of Great arteries (TGA) undergoing Arterial Switch operation (ASO) is an important complication in the post-operative period associated with worse outcomes. AKI in children post open cardiac surgery has been well studied, with lesser data in literature pertaining to TGA and its sub-types specifically. This was a prospective, observational study enrolling infants with TGA undergoing ASO at a single center over a span of a decade from January 2010 to December 2020. The infants were followed during the duration of ICU and hospital stay, with documentation of baseline and intraoperative parameters as well as post-operative course. Out of 145 infants enrolled in the study, 83.1% developed AKI with majority (83.9%) having stage 1 AKI. Higher odds of AKI were seen in infants requiring Norepinephrine [odds ratio - 16.76 (95% CI 2.19-128.2), p < 0.001] and those who developed gram-negative infections [2.81 (1.04-7.56), p - 0.036]. Infants with AKI had significantly higher vasoactive-inotropic support at day 1 than those without AKI [16 (12.5-21.50 vs 13 (10.25-15.75), p - 0.014]. Seventeen infants in the AKI group (14%) died as opposed to none in the non-AKI group (p = 0.076). Median hours of ventilator support required were significantly higher in those with AKI than those who did not develop AKI (48 vs 45.5 p = 0.015). The infants with ASO + ASD + PDA (53% of neonates who died) were younger, had less weight at admission, more gram-negative sepsis and need for dopamine, as compared to ASO + VSD + ASD (23.5% of mortality) and ASO + ASD + VSD + aortic arch repair (23.5% of mortality). AKI in infants with TGA undergoing ASO is common and associated with poorer outcomes. In this subpopulation, AKI development is associated most commonly with hemodynamic instability and infections. This is the first study, looking at outcomes of TGA depending on the sub-types of ASO surgeries done in the infants [ASO with ASD + PDA or ASD + VSD or ASD + VSD + Arch Repair].
