Abstract:
Objective To compare the effects of mild hypothe rmic cardiopulmonary bypass (CPB) and moderate hypothermic cardiopulmonary bypas s in pediatric cardiac surgery. Methods A total of 118 cas es of less than 3 years of age that had undergone open heart surgery were review ed, in which 46 patients received moderate hypothermic CPB(group 1) and 72 patie nts received mild hypothermic CPB(group 2). The CPB duration, incidence of low c ardiac output and postoperative concentration of CK-MK, etc, were compared with each other betwee n the two groups. Results Duration of bypass and postoperative mechanical respiratory assistance of group 2 was shorter than that of group 1 ( P<0.05). Transfusion requirements, incidence of low cardiac output syndrome, concentration of CK-ME and percentage of metabolic acidosis were lower in grou p 2 than in group 1 (P<0.05), while the index of oxygenation was higher in g roup 2(P<0.05). Conclusion The mild hypothermic CPB is saf er and more effective and therefore is superior to moderate hypothermic CPB in p ediatric cardiac surgery.
