前置胎盘孕妇产前彩色多普勒超声检查预测分娩出血的临床价值

Clinical value of prenatal color Doppler ultrasonography in predicting delivery bleeding in pregnant women with placenta previa

目的:探讨前置胎盘孕妇产前彩色多普勒超声检查预测分娩出血的临床价值。方法:收治前置胎盘孕妇64例。孕妇均进行产前超声检查,分析孕妇产前超声检查结果与并发分娩时大出血的临床价值。结果:大出血组的胎盘主要附着部位、有无胎盘缺损、胎盘植入率、既往子宫手术史与非大出血组差异有统计学意义(P<0.05),胎盘主要附着于前壁、存在胎盘缺损、胎盘植入、既往子宫手术史是分娩大出血的危险因素(P<0.05)。结论:对前置胎盘孕妇进行彩色多普勒超声检查,发现胎盘缺损及植入、胎盘主要附着于前壁和既往子宫手术史,均增加了患者剖宫产时发生大出血的概率,可对孕妇分娩大出血的危险性做出有效的预测和评估。

Objective:To investigate the clinical value of prenatal color Doppler ultrasonography in predicting the bleeding of childbirth in pregnant women with placenta previa.Methods:64 pregnant women with placenta previa were examined by prenatal ultrasound.The clinical value of prenatal ultrasound examination and massive hemorrhage during delivery were analyzed.Results:The placental hemorrhage group mainly attachment site and there was no statistical significance of placental defects,placenta implantation rate,previous history of uterine surgery and non bleeding group(P<0.05).Placenta mainly attached to the front wall,placental defect,placental implantation,previous uterine surgery was childbirth bleeding risk factors(P<0.05).Conclusion:Color Doppler ultrasound examination of pregnant women with placenta previa,placental implantation,placental defects and mainly attached to the front wall and past history of uterine surgery,increased the probability of bleeding occurred when patients with cesarean delivery,make a prediction and evaluation on the risk of bleeding in pregnant women.
