目的探讨M型彩色多普勒超声测量心室舒张早期血流传播速度(Vp)在宫内窘迫胎儿心室舒张功能评价中的应用价值。方法选取2014年1月-2015年11月在该院产科门诊进行检查或住院的,诊断为宫内窘迫的胎儿50例为宫内窘迫组,M型彩色多普勒超声心动图测量33~42周胎儿Vp值,随机抽取对应孕周80例正常胎儿为对照组,将两组进行比较。结果宫内窘迫胎儿左、右心室Vp值均分别低于正常对照组左、右心室,差异有统计学意义(P<0.05)。结论应用M型彩色多普勒测量Vp,有助于及时发现宫内窘迫胎儿心室舒张功能异常。
Objective To investigate the value of M-mode color Doppler ultrasound in the measurement of early ventricular diastolic blood flow velocity (Vp) in the evaluation of left ventricular diastolic function in fetal distress. Methods From January 2014 to November 2015, 50 fetuses diagnosed as intrauterine distress were examined or hospitalized in the department of obstetrics and gynecology. Fifty fetuses with intrauterine distress were classified as intrauterine distress group. M-mode color Doppler echocardiography was used to measure 33-42 Week fetus Vp value, randomly selected gestational weeks corresponding to 80 normal fetuses as control group, the two groups were compared. Results The left ventricle and the right ventricle were lower in left ventricle and right ventricle of left ventricular in patients with intrauterine distress, respectively, which were significantly lower than those in normal control group (P <0.05). Conclusion Using M-mode color Doppler to measure Vp is helpful to find out abnormal fetal ventricular diastolic function in time.
