本文回顾性地分析１９９４ 年１０ 月至１９９８ 年１０ 月在本院产前病区住院孕妇单胎妊娠中测得３１ 例脐动脉血流Ｓ／Ｄ≥４ 围产儿结局：ＩＵＧＲ 的发生率为６７－７ ％ ；新生儿窒息率为４５－１％ ；围产儿死亡率为３２－２ ％ ；胎儿畸形率为１９－４ ％ 。本文还发现与脐带因素密切相关，脐带异常占６４－５ ％ 。结合无负荷试验（ＮＳＴ） 结果显示：３１ 例Ｓ／Ｄ≥４ 中ＮＳＴ 评分＜ ７ 分组较ＮＳＴ 评分≥７ 分组围产儿死亡、羊水ⅡⅢ°粪染明显增高（Ｐ组均＜０－０２５） ，表明围产儿预后更差。ＮＳＴ≥７ 组较ＮＳＴ 评分＜７组脐带异常的发生率明显增高（Ｐ值＜０－０２５） 。提示：结合胎心监护可更准确评估胎儿宫内情况。动态观察脐动脉血流Ｓ／Ｄ 值，结合胎心监护，可作为估价胎儿安全的一种最佳方法［１］ 。本文结合胎心监护回顾性地分析脐动脉血流Ｓ／Ｄ≥４ 围产儿结局。
This retrospective analysis of October 1994 to October 1998 in our hospital antenatal ward hospitalized pregnant women with singleton pregnancies measured 31 cases of umbilical artery blood flow S / D ≥ 4 perinatal outcome: the incidence of IUGR 67 -7%; neonatal asphyxia was 45-1%; perinatal mortality was 32-2%; fetal malformation rate was 19-4%. This article also found that closely related with the umbilical cord factors, umbilical cord anomalies accounted for 64-5%. Combined with no-load test (NST), 31 patients with NST score less than 7 in S / D≥4 died more than those with NST score≥7 and amniotic fluid Ⅱ-Ⅲ stool infection was significantly increased (all P <0-025 ), Indicating that the prognosis of perinatal worse. The incidence of umbilical cord abnormality in NST group was significantly higher than that in NST group (P <0-025). Tip: combined with fetal heart rate monitoring can be more accurate assessment of intrauterine conditions. Dynamic observation of umbilical artery blood flow S / D values, combined with fetal heart rate monitoring, can be used as a valuation of fetal safety is the best method [1]. This article combined with fetal heart rate monitor retrospectively analyzed umbilical artery blood flow S / D ≥ 4 perinatal outcome.
