目的:探讨彩超对妊娠晚期胎儿脐带绕颈的临床诊断价值。方法:对产前1周的孕妇300例行彩超检查,检出脐带绕颈82例,测脐动脉阻力指数(RI)、收缩期与舒张末期的最大血流速度比值(S/D),与分娩结果对照分析。结果:脐带绕颈且发生宫内窘迫组RI、S/D值明显高于无脐带绕颈组(P<0.05)。结论:脐动脉血流RI、S/D值是判断脐带绕颈胎儿宫内缺氧的可靠指标,对临床选择分娩方式具有指导意义。
Objective: To investigate the value of color Doppler ultrasonography in the diagnosis of fetal umbilical cord around the neck in the third trimester of pregnancy. Methods: The color Doppler echocardiography was performed on 300 pregnant women during the first prenatal week. 82 cases of umbilical cord around the neck were detected. The resistance index (RI), maximum systolic velocity (S / D), systolic and diastolic velocity were measured. Control of childbirth results. Results: RI and S / D values of umbilical cord around neck and intrauterine distress group were significantly higher than those of umbilical cord around neck (P <0.05). Conclusion: The RI and S / D values of umbilical artery blood flow are reliable indicators to judge the uterine hypoxia around the umbilical cord around the neck, which is instructive for the clinical choice of mode of delivery.
