Clinical Comparison Of Beating-Heart And Arrested-Heart Intracardiac Procedure In Pediatrics

Objective: To compare the effects of mild hypothermia beating-heart cardiopulmonary bypass (CPB) with those of moderate hypothermia arrested-heat CPB in pediatric intracardiac procedure.Methods: 56 patients whose age were under 3 years underwent open heart surgery. In group 1, 26 patients underwent arrested-heart operation, and in group 2 ,30 patients underwent beating-heart operations.Duration of CPB and surgery ,postoperative mechanical respiratory assistance duration and incidence of low cardiac output, ect ,were compared between the tow groups.Results: Duration of CPB and operative duration in group 2 were shorter than those in group 1 (P<0.01),and postoperative mechanical respiratory assistance duration was shorter in group 2. The incidence of low cardiac output syndrome and serious cardiac arrhythmia in group 2 was lower than those in group 1, and postoperative residential duration was shorter in group 2.Conclusion: The effect of mild hypothermia beating-heart CPB is superior to that of moderate hypothermia arrested-heart CPB in pediatric cardiac surgery. Therefore, the mild hypothermia beating-heart CPB is a safe abd effective technique applied to pediatric cardiac surgery.
