摘要
本文分析自1984年11月～1988年6月妊娠并发脐带异常301例的胎心监护图,试图从中找出发生脐带异常时胎心图表现的一些规律,并预测胎儿受损程度。本文对异常胎心图的类型、出现频率及与羊水、胎儿预后的关系进行了探讨。重度可变减速和心动过速常预示胎儿窘迫,应积极中止妊娠。
A retrospective analysis of FHR monitoring patterns in 301 pregnant women with abnormal umbilical cords from Nov. 1984 to June 1988 was presented. 620 NST and CST were all performed within 7 days before deliveries. Among 301 cases 163(54. 15%)were normal FHR monitoring patterns, and 138 (45. 85%) abnormal FHR monitoring patterns. Of the abnormal FHR group, variable deceleration appeared in 93 cases (67. 39%), tachycardia in 31 cases (22. 4%), both together occupied the major portion of the group. The meconium-stained amniotic fluid rate was correlated with the abnormal FHR pattern. It increased to 28. 36% in abnormal FHR group while 12. 96% in normal. Various types of variable deceleration and tachycardia may be considered one of the signs of cord problems. Fetal distress was usually predicted in the severe variable deceleration and tachycardia cases which need an immediate termination of pregnancy. Both perinatal mortality and morbidity rate were increased in the cases with abnormal fetal heart monitoring pattern (36. 30% and 5. 22 % respective)ly in comparison with the normal monitoring pattern (6.13% and 7.36% respectively). The importance of FHR monitoring in perinatal period, especially during labor or induced labor, should be emphasized.
