本文对548例初产妇临产后常规进行电子胎心监护,经监护诊断为胎儿窘迫(称监护异常)51例,发生率为9.31%,妊娠37周以后,监护异常的发生率随孕周的增加逐渐上升,孕37～39~(+6),40～41~(+6),≥42周的发生率分别为5.3%,0.6%,23.5%.51例监护异常者中,30例(58.8%)有异常胎心或(和)羊水污染Ⅲ度的临床表现,21例(41.2%)无上述表现.监护异常者的新生儿1min和5min Apgar低评分发生率明显高于监护正常者,特别是伴有基线变异性减少时,明显增加1min低评分.产时监护能早期发现胎儿宫内缺氧,对降低围产儿的发病率及死亡率有重要意义, In this paper, 548 cases of primipara postpartum routine electronic fetal heart monitoring, monitoring of fetal distress (referred to custody abnormalities) in 51 cases, the incidence was 9.31%, after 37 weeks of pregnancy, the incidence of monitoring abnormalities increased with gestational age (+6), 40 ~ 41 ~ (+6), and the incidence of ≥42 weeks were 5.3%, 0.6% and 23.5%, respectively.Among the 51 cases of abnormal monitoring, 30 cases (58.8% %) Had abnormal fetal heart rate or (Ⅲ) degree of amniotic fluid contamination clinical manifestations, 21 cases (41.2%) did not show the above .Annual monitoring of neonates 1min and 5min Apgar low score was significantly higher than the normal guardianship, especially Is accompanied by a decrease of baseline variability, a significant increase in 1min low score. Childhood intrauterine fetal protection can be found early hypoxia, reduce the incidence of perinatal mortality and mortality is important,
