本文对４８４例高危妊娠病人行多普勒测定脐动脉血流速度收缩期与舒张期的比值（Ｓ／Ｄ），无负荷试验（ＮＳＴ）产的监护，监护异常者１７８例。Ｓ／Ｄ异常组（１１１例）中ＣＳＴ异常的发生率（４１．４％）高于ＮＳＴ异常组（２６．２％）（Ｐ＜０．０５）；而新生儿１和５ｍｉｎＡｐｇａｒ低分的发生卒ＮＳＴ异常组较高（Ｐ＜０．０５）。在Ｓ／Ｄ异常同时伴有ＮＳＴ异常组（２５例）中。ＣＳＴ异常、Ａｐｇａｒｌ和５ｍｉｎ低分的发生率最高（Ｐ＜０．００１）。临床胎儿窘迫和分娩时羊水胎粪污染的发生率在监护异常的三组中无差异（Ｐ＞０．０５）。结果提示，应用脐动脉血流速度监护力这能较早地提供胎儿宫内危险信号。
In this paper, 484 cases of high-risk pregnancy Doppler measurement of umbilical artery blood flow systolic and diastolic ratio (S / D), no-load test (NST) of the guardianship, monitoring of abnormalities in 178 cases. The incidence of CST abnormalities in S / D abnormalities group (41.4%) was higher than that in NST abnormalities group (26.2%) (P <0.05), while neonatal 1 and 5 minutes Stroke NST abnormal group was higher (P <0.05). In the S / D abnormalities accompanied by NST abnormal group (25 cases). CST abnormalities, Apgarl and 5min low score the highest incidence (P <0.001). Clinical fetal distress and amniotic meconium contamination during childbirth in the incidence of abnormal monitoring of the three groups was no difference (P> 0.05). The results suggest that the use of umbilical artery blood flow monitoring force which can provide early fetal intrauterine signal of danger.
