摘　　要：目的探究组织多普勒成像技术(TDI)在慢性胎儿窘迫产前诊断中的价值。方法选取2012年1月至2013年6月接受TDI检查的慢性胎儿窘迫晚孕单胎孕妇48例作为的实验组;另外选取同期接受TDI检查的正常晚孕单胎孕妇48例为对照组。测量两组胎儿的心肌运动速度(MV)以及房室瓣环的Tei指数,分析两组数据。结果 MV频谱可见S、E、A三个主峰,实验组胎儿左室壁MV分别为(4.12±1.15)、(5.11±1.33)、(4.02±1.21)cm/s,较对照组低,差异有统计学意义(P<0.05)。实验组胎儿Tei指数为(0.56±0.10),对照组为(0.49±0.09),差异有统计学意义(P<0.05)。结论 TDI检查中MV、Tei指数对慢性胎儿窘迫具有诊断价值,值得在临床上进一步推广。Objective To study the diagnostic value of tissue Dopple imaging （TDI） technology for chronic fe-tal distress .Methods A total of 48 cases of late singleton pregnant women with chronic fetal distress （experiment group） and 48 cases of healthy late singleton pregnant women （control group） receiving TDI examination from Janu-ary 2012 to June 2013 were enrolled .Myocardial velocity （MV） and the Tei index of the two groups were measured and analyzed .Results Three main peaks of MV could be detected ,including S ,E and A main peak ,and the detected values of the three main peaks in experiment group were （4 .12 ± 1 .15） ,（5 .11 ± 1 .33） and （4 .02 ± 1 .21）cm/s , which were lower than control group （P〈0 .05） .The Tei index of experiment group was 0 .56 ± 0 .10 ,which was significantly different with the 0 .56 ± 0 .10 of control group （P〈0 .05） .Conclusion The MV and Tei index of TDI examination might be with diagnostic value for chronic fetal distress ,which could be worthy for further promotion in clinic .
