摘要自1980年1月～1991年11月共施行婴幼儿法乐四联症根治术234例.平均年龄1岁9个月.平均体重9.7kg.手术死亡20例,病死率为8.5%,近五年病死率降至6.6%.讨论了降低病死率的主要因素:手术组成员的相对稳定;体外循环基本方法的改进,尤其是深低温、低流量、高稀释灌注技术的应用,手术关键的掌握和术后的妥善处理等.

abstractsFrom Jan.1980 to Dec.1991,234 infants of Tetralogy of Fallot (TOF) underwent primary repair.Of them age ranged from 2 months to 3 years with an average of 1.9 yrs,and weight from 4.5 to 16.5kg with an average of 9.7kg.Mortality has decreased from 8.5% to 6.6% in recent five years.The outcome of operation on affected infants has been enhanced by following factors:(1) improved surgical techniques and rather stable operative team,(2) the use of deep hypothermla,hypoperfusion and hyperdilution,and profound hypothermia with circulatory arrest for infants weighting under 8kg,and (3)appropriate postoperstive management containing small dose of Dopamine and large dose of diuretica and digoxin etc.
