摘　　要：目的:探讨Tei指数对于法洛氏四联症(tetralogy of Fallot,TOF)患儿术后的临床价值。方法:自2008年10月至2012年6月间来我院就诊的TOF患儿45例,术后先行超声Tei检测,根据结果分为3组,A组:Tei指数<0.5,B组:0.5≤Tei指数<0.7,C组:Tei指数≥0.7。行超声心动图检查测量左室射血分数(ejection fraction,EF)、计算右心Tei指数、记录呼吸机辅助时间、重症监护室监护时间、正性药物辅助时间、引流量。结果:A组与B组、C组患儿在呼吸机辅助时间、重症监护室监护时间、正性药物辅助时间、引流量等方面差异具有统计学意义。Tei指数与之具有负相关关系,EF在3组中差异无统计学意义。结论:Tei指数可以较敏感准确地反映TOF患儿右室功能的变化,是一个简单且有价值的临床指标。Objective ：To explore the clinic value of Tei index in assessing right ventricular function of patients with TOF（tetralogy of Fallot） postoperatively. Methods ：Totally 46 patients with TOF were enrolled and were divided into 3 groups according to the Tei in- dex：Tel index 〈0.5（group A,n=13）;0.5 ≤Tei index 〈0.7（group B,n=19）;Tel index ≥0.7（group C,n=13）. Ejection fraction of left ventricle （EF） was measured. Right ventricle Tel index was calculated and ventilation time, ICU stay, positive drug time, drainage vol- ume were recoreded. Results ： There were statistical differences in ventilation time, ICU stay, positive drug time, drainage volume a- mong three groups. Tei index was negatively correlated with ventilation time, ICU stay, positive drug time and drainage volume. There was no difference in EF among three groups. Conclusions ：Tei index is a sensitive indicator of right ventricnlar function and is a valu- able and easy indicator in clinics.
