施行婴幼儿法乐四联症（ＴＯＦ）根治术１９１例。年龄０．５～３．０岁，１岁以下３０例。体重５．５～１４．２ｋｇ。手术死亡７例，病死率３．６６％。指出灌注肺是本组手术后死亡的主要因素（Ｐ＜０．０５），而左心室大小、肺动脉大小、合并畸形等并不是影响手术结果的主要原因。在死亡的７例中有３例灌注肺患儿，其原因可能与下列因素有关：体外循环放血，过度稀释，开放主动脉钳后发生灌注肺；复温时上下肢温差超过１０℃；体外循环不平稳流量时高时低。
The implementation of infant tetralogy of Fallot (TOF) radical surgery in 191 cases. Age 0.5 to 3.0 years old, under the age of 30 cases. Weight 5.5 ~ 14.2kg. Seven cases died of surgery, the case fatality rate was 3.66%. It is pointed out that perfusion of lung is the main cause of postoperative death in this group (P <0.05), and left ventricular size, pulmonary artery size, combined deformity and so on are not the main reasons that affect the surgical results. Among the 7 deaths, 3 cases were infants with pulmonary infiltrates. The reasons may be related to the following factors: extracorporeal circulation bleeding, excessive dilution, perfusion of the lung after opening of aortic clamp; temperature difference between upper and lower limbs over 10 ° C during rewarming; extracorporeal circulation Unstable flow when high and low.
