【摘要】：目的应用组织多普勒成像Tei指数及肺静脉、静脉导管血流参数综合评估妊娠期高血压患者胎儿心功能,为产前评估胎儿心功能提供有价值的信息。方法选取孕周28~41+6周的孕妇193例,妊娠期高血压孕妇69例为疾病组,与其孕龄匹配且血压正常的孕妇124例为对照组。测量胎儿的各项参数:(1)Tei指数。(2)肺静脉及静脉导管:心室收缩期峰值流速S、心室舒张期峰值流速D、心房收缩期峰值流速A,并计算S/A、静脉搏动指数PI、静脉峰值流速指数PVIV。随访所有新生儿生后1min Apgar评分。结果疾病组胎儿左、右心室Tei指数均较对照组增高(P0.05);疾病组胎儿肺静脉及静脉导管血流参数S、D、A均较对照组减低(P0.05);疾病组胎儿肺静脉及静脉导管指数S/A、PI、PVIV均较对照组增高(P0.05);疾病组胎儿出生后窒息率均较对照组增高(P0.05)。结论通过对妊娠期高血压患者胎儿左、右心室Tei指数及肺静脉、静脉导管血流参数的研究,可对胎儿心功能变化进行监测。
[Abstract]:Objective using tissue Doppler imaging Tei index and pulmonary vein, heart function evaluation of venous catheter blood flow parameters of fetus fetal cardiac function in patients with hypertension, provide valuable information for the prenatal assessment of pregnant women. Methods 28~41+6 weeks of gestation in 193 cases, 69 cases of pregnant women with gestational hypertension disease group, and gestational age, and pregnant women normal blood pressure of 124 patients in the control group. The parameters measurement of fetal: (1) Tei (2). The index of pulmonary vein and venous catheter: left ventricular peak systolic velocity S, ventricular diastolic peak velocity D, peak atrial systolic flow velocity A, and calculate the S/A vein pulsatility index PI, venous peak velocity index PVIV. follow-up all newborns after birth 1min Apgar score. The disease group of fetal left and right ventricular Tei index were higher than those of the control group (P0.05); disease group of fetal pulmonary vein and venous catheter blood flow parameters S, D, A were lower than those in control group (P0. 05); disease group of fetal pulmonary vein and venous catheter index S/A, PI, PVIV were higher than those of the control group (P0.05 group); disease of the fetus after birth asphyxia rate were higher than those of the control group (P0.05). Conclusion the fetus in hypertensive patients with left and right ventricular Tei index and pulmonary vein, blood flow of venous catheter the parameters, can be monitored on fetal cardiac function changes.
