目的：为研究胎儿心电图（FECG）对胎儿宫内缺血缺氧早期诊断中的价值。方法：对240例孕妇应用FECG检查，并追踪观察分娩情况．结果：正常FECG166例（69．17％）；异常FECG74例（30．83％）；异常组经人工破膜及剖宫产术证实有38例（51．35％）发生不同程度羊水胎粪污染；Apgar评分≤7分的新生儿窒息31例（41．89％）。结论：此项检查对胎儿宫内缺血缺氧更具特异性和敏感性，对指导临床及时纠正缺氧，为提高新生儿质量赢得时间． Objective: To investigate the value of fetal electrocardiogram (FECG) in the early diagnosis of intrauterine ischemia and hypoxia. Methods: FECG examination was performed on 240 pregnant women and the status of delivery was observed. Results: The normal FECG166 cases (69.17%); abnormal FECG74 cases (30.83%); abnormal group by artificial rupture of membranes and cesarean section confirmed that 38 cases (51.35%) occurred varying degrees of amniotic fluid meconium contamination 31 cases (41.89%) of neonatal asphyxia with Apgar score ≤7. Conclusion: This test is more specific and sensitive to intrauterine ischemia and hypoxia. It can guide clinical timely correction of hypoxia and gain time for improving newborn quality.
