Empowering Little Fighters: Post-Cardiotomy Pediatric ECMO and the Journey to Recovery.

ABSTRACT

INTRODUCTION: Extra Corporeal Membrane Oxygenation (ECMO) has long been used for cardiorespiratory support in the immediate post-paediatric cardiac surgery period with a 2-3% success as per the ELSO registry. Success in recovery depends upon the optimal delivery of critical care to paediatric patients and a comprehensive healthcare team. METHODOLOGY: The survival benefit of children placed on central veno arterial (VA) ECMO following elective cardiac surgeries for congenital heart disease (n = 672) was studied in a cohort of 29 (4.3%) cases from the period of Jan 2018 to Dec 2022 in our cardiac surgical centre. Indications for placing these patients on central VA ECMO included inability to wean from cardiopulmonary bypass (CPB), low cardiac output syndrome, severe pulmonary arterial hypertension, significant bleeding, anaphylaxis, respiratory failure and severe pulmonary edema. RESULTS: The mean time to initiation of ECMO was less than 5 h and the mean duration of ECMO support was 56 h with a survival rate of 58.3%. Amongst perioperative complications, sepsis and arrhythmia on ECMO were found to be negatively associated with survival. Improvements in the pH, PaO2 levels and serum lactate levels after initiation of ECMO were associated with survival benefits. CONCLUSION: The early initiation of ECMO for paediatric cardiotomies could be a beacon of hope for families and medical teams confronting these challenging situations. Improvement in indicators of adequate perfusion and ventricular recoveries like pH and serum lactate and absence of arrhythmia and sepsis are associated with good outcomes.
