为探讨孕晚期胎儿电子监护（ Ｎ Ｓ Ｔ） 仪监测结果与 Ｂ 超、多谱勒脐血流、羊膜镜等检查的关系。本文对１１５ 例３２ 孕周之后的胎儿 Ｎ Ｓ Ｔ 无反应型产妇通过吸氧、进食及进一步做催产素激惹试验（ Ｏ Ｃ Ｔ） 等，筛选出 Ｎ Ｓ Ｔ 假无反应型、 Ｏ Ｃ Ｔ 阴性、 Ｏ Ｃ Ｔ 阳性患者，同时随机选择５０ 例 Ｎ Ｓ Ｔ 反应正常者做对照组，对４ 组产妇均做 Ｂ 超、多谱勒脐血流、羊膜镜等，并统计妊娠结局。结果 Ｎ Ｓ Ｔ 反应型与假无反应型、 Ｏ Ｃ Ｔ 阴性相比，其羊水过少、胎盘钙化、羊水污染、脐血流异常及妊娠结局等均 Ｐ＞ ００５ ，而与 Ｏ Ｃ Ｔ 阳性组相比 Ｐ＜ ００５ 。提示临床应用 Ｎ Ｓ Ｔ 应反复多次，并结合 Ｂ 超、脐血流等慎重处理 Ｏ Ｃ Ｔ 阳性患者，以提高产科质量，降低手术产率。
To investigate the third trimester fetal electronic monitoring (N S T) meter monitoring results and B ultrasound, Doppler umbilical cord blood flow, amnioscopy and other tests. In this paper, 115 cases of 32-week-old fetus NST non-reactive mothers through oxygen, eating and further oxytocin challenge test (O C T), screening N S T false non-reactive type, O C T Negative and O C T-positive patients. At the same time, 50 patients with NST-positive reaction were randomly selected as the control group. B-ultrasound, Doppler sonography, and amnioscopy were performed on the 4 groups of women. Pregnancy outcomes were calculated. Results Compared with the false negative and non-negative O C T negative, N S T reaction showed oligohydramnios, placental calcification, amniotic fluid contamination, umbilical cord blood flow abnormality and pregnancy outcome (all P> 005) Positive group compared P <0 05. It is suggested that NST should be repeated many times in clinical practice, and combined with B-ultrasound, umbilical blood flow and other cautious O C T-positive patients to improve obstetric quality and reduce surgical yield.
