目的:探讨多普勒脐动脉血流速度检测、无负荷试验(NST)联合应用预测围生儿结局的临床价值。方法:将158例NST监测异常的孕妇分为2组,即高危妊娠组(妊娠合并症组)和正常妊娠组,进行多普勒脐动脉血流阻力(S/D)测定。结果:高危妊娠组围生儿预后不良发生率明显高于正常妊娠组。距最后一次检测时间2 d内分娩的孕妇围生儿,预后不良发生率明显低于3~7 d分娩的孕妇(P<0.05)。结论:NST异常、脐动脉血流阻力S/D值正常者,无需过早干预妊娠,可动态观察。NST异常且S/D值异常者,宜尽早终止妊娠。
Objective: To investigate the clinical value of Doppler umbilical artery blood flow velocity test and no-load test (NST) in predicting perinatal outcome. Methods: Fifty-eight pregnant women with NST abnormalities were divided into two groups: high-risk pregnancy group (pregnancy complications group) and normal pregnancy group. The Doppler U-flow resistance (S / D) was measured. Results: The incidence of adverse prognosis of perinatal children in high-risk pregnancy group was significantly higher than that in normal pregnancy group. The incidence of adverse prognosis in pregnant women with childbirth within 2 days after the last test was significantly lower than that of pregnant women with childbirth within 3 to 7 days (P <0.05). Conclusion: NST abnormalities, umbilical artery flow resistance S / D values were normal, without premature pregnancy intervention can be dynamically observed. Abnormal NST and S / D values abnormalities, should terminate the pregnancy as soon as possible.
