目的探讨产时胎心监护中导致胎心率晚期减速的因素、处理方法及新生儿情况。方法对我院2008～2010年46例产时监护中胎心率晚期减速的临床资料进行回顾性分析,总结其发生原因、处理方法。结果 46例中脐绕颈6例,羊水过少5例,子痫前期4例,过期妊娠3例,贫血3例,胎盘早剥1例,无妊娠合并症及妊娠并发症24例。新生儿Apgar评分,5min评分,7～10分33例,4～7分9例,2～3分4例。结论产时胎心监护特别是对有妊娠合并征及妊娠并发症的孕妇进行持续性胎心监护,在正常宫缩条件下,晚期减速连续出现3次,尤其是产程早期或者是虽在产程晚期但合并基线过缓,变异消失,提示胎儿危险,应尽快处理[1]。
Objective To investigate the factors that lead to late deceleration of fetal heart rate during labor during labor and the treatment methods and neonatal conditions. Methods A retrospective analysis was made on the clinical data of 46 cases of late fetal heart rate deceleration in our hospital from 2008 to 2010, and the causes and treatment methods were summarized. Results 46 cases of umbilical cord around the neck in 6 cases, 5 cases of oligohydramnios, 4 cases of preeclampsia, 3 cases of premature pregnancy, anemia in 3 cases, 1 case of placental abruption, no complications of pregnancy and pregnancy complications in 24 cases. Neonatal Apgar score, 5min score, 7 to 10 points in 33 cases, 4 to 7 in 9 cases, 2 to 3 in 4 cases. Conclusion During labor, the fetal heart rate monitoring especially for pregnant women with pregnancy complicated with complications of pregnancy carries on the continuous fetal heart rate monitoring. Under normal contractions, the late deceleration occurs three times in a row, especially in the early stage of labor or in late stage of labor However, the merger baseline was too slow, the mutation disappeared, suggesting that the fetus is dangerous and should be dealt with as soon as possible [1].
