产时胎心监护减速区面积在新生儿酸中毒预测中的价值

Value of Intrapartum Fetal Heart Rate Monitoring Retardation Area in the Prediction of Neonatal Acidosis

目的预测新生儿酸中毒应用产时胎心监护减速区面积的价值。方法回顾性分析我院2016年1月至2018年1月102例住院分娩产妇分娩前半小时的胎心监护图形的减速区面积,按照pH值进行分组,pH<7.2的产妇纳入酸中毒组,共13例,另外pH≥7.2的产妇纳入对照组,共89例,分析产时胎心监护减速区面积和新生儿脐动脉血气的相关性。结果酸中毒组新生儿窒息发生率7.69%,明显高于对照组0%(P<0.05),酸中毒组分娩前30 min减速区面积明显大于对照组(P<0.05)。结论利用产时胎心监护减速区面积预测新生儿酸中毒存在较高特异性,不过缺乏良好敏感性,有必要与更多临床指标相结合进行判断,以保证更高的准确性。

Objective To investigate the value of intrapartum fetal heart rate monitoring retardation area in the prediction of neonatal acidosis.Methods At 0.5 h before delivery,fetal heart rate monitoring retardation area of 102 cases of pregnant women in our hospital from January 2016 to January 2018 were retrospectively analyzed,they were divided according to the pH value,pregnant women with pH<7.2 were seen as the acidosis group(n=13),other pregnant women with pH≥7.2 were seen as the control group(n=89),analyze the relation between the intrapartum fetal heart rate monitoring retardation area and newborn umbilical arterial blood gas.Results Neonatal asphyxia rate of the acidosis group(7.69%)was significantly higher than that in the control group(0%),P<0.05,30 min before delivery,retardation area in the acidosis group was significantly larger than that in the control group,P<0.05.Conclusion The application of intrapartum fetal heart rate monitoring retardation area in the prediction of neonatal acidosis has higher specificity,but lack of good sensibility,combination?judgement with clinical indexes should be taken attention,in order to guarantee higher accuracy.
