DURATION OF CARDIOPULMONARY BYPASS AND MYOCARDIAL ISCHEMIA AS PREDICTORS OF SEVERE INOTROPIC SUPPORT IN CHILDREN WITH TETRALOGY OF FALLOT AFTER RADICAL CORRECTION

This study investigates the impact of cardiopulmonary bypass duration and myocardial ischemia time on the development of severe inotropic support in children undergoing radical correction of Tetralogy of Fallot. A retrospective analysis was conducted on pediatric patients who underwent surgical correction, assessing perioperative parameters including bypass duration, aortic cross-clamp time, and postoperative hemodynamic status. The findings indicate that prolonged cardiopulmonary bypass and myocardial ischemia are significantly associated with an increased need for high-dose inotropic support in the early postoperative period. These factors can serve as important predictors of postoperative cardiac dysfunction and may guide perioperative management strategies aimed at improving clinical outcomes.
