为降低过期妊娠的围产儿患病率及死亡率，对８６ 例过期妊娠患者在临产早期进行胎心电子监护和羊膜镜检查，并与前期３０４ 例未监护进行对照。结果：监护组新生儿窒息率１８－６％ ，对照组窒息率３３－６％ 。经统计学处理差异显著。在监护组中１０ 例减速性胎心变化者有６ 例合并有羊膜镜检查异常，而６ 例加速性胎心变化中只有１ 例合并羊水异常。结果提示：临产早期胎心监护结合羊膜镜检查可以显著降低围产儿患病率。重视减速性胎心变化对优生优育有重要意义。
In order to reduce the incidence of perinatal morbidity and mortality in outdated pregnancies, 86 cases of pregnant women with preterm labor underwent fetal heart electronic monitoring and amniocentesis in the early stage of labor and were compared with the 304 uninsured patients in the first trimester. Results: Guardian neonatorum asphyxia 18-6%, control group asphyxia 33.6%. The difference was statistically significant. In the monitoring group, 10 cases of decelerated fetal heart rate changes were associated with amniogram abnormalities in 6 cases, while only 6 cases of accelerated fetal heart rate changes associated with amniotic fluid abnormalities. The results suggest that: early labor early fetal heart rate monitoring combined with amniocentesis can significantly reduce the prevalence of perinatal. Emphasis on decelerating fetal heart rate changes of prenatal and postnatal care is of great significance.
