摘　　要：目的：探讨脐动脉彩超S／D值测定对评估脐带绕颈预后的临床意义。方法：回顾性分析128例脐带绕颈临产前脐动脉S／D值，按S／D〈2．5、S／D2．5～3.0、S／D〉3.0分组分别观察不同S／D值与胎儿预后的关系。结果：随着S／D值的增大，胎儿酸中毒、羊水污染及新生儿窒息的发生率呈同步上升，剖宫产率也随之同步上升，组间比较差异均有显著性，P〈0．05。结论：诊断脐带绕颈者，临产前应测量其脐动脉S／D值，S／D2．5～3.0者，要采取改善胎儿缺血、缺氧的措施，并加强胎儿电子监护；当S／D〉3．0时，提示胎儿可能有宫内窒息，宜以剖宫产结束分娩。Objective：To study the clinical significance of the prognosis of umbilical cord circling neck by umbilical artery color Doppler S/D determination. Methods： Umbilical artery S/D values were retrospectively analyzed in 128 cases with umbilical cord circling neck. The patients were grouped into three groups according to S/D ratio as S/D 〈 2.5, S/D 2.5 - 3.0, and S/D 〉 3.0, and the relationship of S/D values and fetal prognosis was investigated. Results： The incidence of fetal acidosis, amniotic fluid contamination, and neonatal asphyxia increased with the increment of S/D ratio, as well as the rate of Cesarean Section. There was significantly difference among each group （ P〈 0.05） .Conclusions： In patients with umbilical cord around neck, it is necessary to measure umbilical artery S/D ratio. When S/D ratio was 2.5 - 3.0, improvement of fetal hypoxia and fetal electronic monitoring must be taken. However, Cesarean section is suitable if S/D ratio excess 3.0 which hinting fetal intrauterine asphyxia.
