目的 探讨漏斗胸术后心脏功能的变化。方法 用超声心动图测定４１ 例漏斗胸患儿术前、术后的心脏功能， 并选择年龄、性别、身高、体重相同的正常儿童作对照。结果 漏斗胸患儿术前射血分数（ＥＦ） 与平均左心室周径缩短率（ＭＶＣＦ）与对照组相比有降低（ Ｐ＜ ０．０５）， 长期随访发现患儿术后ＥＦ、ＭＶＣＦ与每搏输出量较术前有上升（ Ｐ＜ ０ ．０１）， 而且这些指标与对照组相比差异无显著性（ Ｐ＞ ０ ．０５） 。结论 漏斗胸术后患儿的心脏功能可恢复正常。
Objective To investigate the changes of cardiac function after funneling thoracic surgery. Methods Echocardiography was used to determine the cardiac function of 41 children with funnel chest and preoperative and postoperative heart function. The control group was normal children of the same age, gender, height and weight. Results The preoperative ejection fraction (EF) and mean left ventricular circumference shortening (MVCF) of the funnel chest decreased compared with that of the control group (P <0.05). After long-term follow-up, EF, MVCF and Stroke volume increased compared with the preoperative (P <0.01), and these indicators compared with the control group no significant difference (P> 0.05). Conclusion The function of heart in children with funnel chest surgery can be restored to normal.
