目的探讨电子胎心监护与胎儿窘迫及剖宫产率之间的关系。方法回顾分析4674例住院分娩孕妇的胎心电子监护图形。结果发现胎心监护图形异常者382例,其中223例考虑胎儿窘迫行剖宫产术,术中发现异常因素者175例,未发现异常因素者48例。胎心基线变异明显减弱或消失、重度变异减速、延长减速及晚期减速者发生羊水粪染、脐带缠绕及新生儿窒息比例明显高于其它胎心监护图形异常者。结论电子胎心监护能早期发现胎儿窘迫,但是,单凭胎心监护图形异常作为胎儿窘迫诊断会出现假阳性判断,当出现异常图型时,应严密监护,根据胎心率异常的程度及胎儿能够娩出的时间选择恰当的分娩方式,可减少围产儿病死率。
Objective To explore the relationship between electronic fetal heart rate monitoring and fetal distress and cesarean section rate. Methods Retrospective analysis of 4674 cases of pregnant women in hospital delivery fetal heart electronic monitoring graphics. The results showed that 382 cases of fetal heart rate monitoring abnormalities, of which 223 cases of fetal distress cesarean section, intraoperative findings of abnormalities in 175 cases, no abnormalities in 48 cases. The baseline variation of fetal heart rate was significantly weakened or disappeared, with severe variant decelerations, prolonged decelerations and late decelerations occurred in those with meconium - stained amniotic fluid, umbilical cord entanglement and neonatal asphyxia were significantly higher than those in other fetal heart rate monitoring abnormalities. Conclusion Fetal fetal distress can be detected early, however, the diagnosis of fetal distress based on fetal Fetal ECG abnormality can be falsely positive. When there is an abnormal pattern, it should be closely monitored. According to the degree of fetal heart rate abnormality and fetus The timing of the delivery can be chosen by the appropriate mode of delivery to reduce perinatal mortality.
