目的应用心室内血流传播速度检测评价糖尿病孕妇胎儿的心功能变化。方法选择2008年1月~2012年12月来20~40周超声心动图检查的正常胎儿300例,应用M型彩色多普勒测定心室内舒张早期血流传播速度(the propagation velocity,Vp),以正常胎儿为对照组,评价29例糖尿病孕妇胎儿Vp变化情况。结果母亲妊娠期糖尿病胎儿心室Vp值较正常对照组降低(P<0.01)。结论妊娠期糖尿病孕妇胎儿的心室功能会受到损害,心室内舒张期血流传播速度可作为检测评价糖尿病孕妇胎儿心室舒张功能的有效新指标。
Objective To evaluate the changes of cardiac function in the fetus of diabetic pregnant women by using the ventricular blood flow velocity test. Methods 300 normal fetuses with echocardiography at 20-40 weeks from January 2008 to December 2012 were selected. The propagation velocity (Vp) was measured by M-mode color Doppler, The normal fetus as control group, evaluation of 29 cases of diabetic fetus Vp changes. Results Compared with the normal control group, the Vp of fetus in gestational diabetic fetus decreased (P <0.01). Conclusions Fetal ventricular function may be impaired in pregnant women with gestational diabetes mellitus. The velocity of ventricular diastolic blood flow can be used as a new effective measure to evaluate the fetal diastolic function in diabetic pregnant women.
