Fetal heart monitoring and blood gas analysis of perinatal infants with abnormal umbilical cord
脐带异常围生儿监测的胎心监护及血气分析应用

摘要

目的 分析脐带异常围生儿监测的胎心监护和血气分析应用。方法 分析在我院2021年 3月~2022年5月接受治疗的单胎足月孕妇80例对象，在所有孕妇分娩过程中都给予胎心监护，之后均分成对照组和实验组，每组40例，所有胎儿在产出后都进行脐动脉血气分析，比较两组新生儿窒息、胎儿窘迫、剖宫产、酸中毒和产钳情况。结果 两组患者的羊水污染Ⅰ°、Ⅱ°比率之间的差异均不显著，但实验组患者的Ⅲ°比率高于对照组（P<0.05）；两组患者的剖宫产、产钳、死亡比率之间的差异均不显著（P>0.05）；两组围生儿的胎心监护VD、LD、VD+LD比率之间的差异均不显著（P>0.05）；两组围生儿的Apgar评分0-3分、4-7分、8-10分比率之间的差异均不显著（P>0.05）。实验组患者的PO2、PCO2均高于对照组（P<0.05），pH、BE均低于对照组（P<0.05），出现酸中毒情况明显高于对照组，组间差异显著（P<0.05）。结论 对于脐带异常围生儿使用胎心监护结合血气分析，可以有效检测胎儿缺氧、缺血情况，同时也能减少新生儿窒息率和胎儿窘迫情况，胎儿临床存活率比较高，临床使用价值很大。

Abstract

Objective To analyze the application of fetal heart monitoring and blood gas analysis in monitoring perinatal infants with abnormal umbilical cord.
Methods 80 full-term singleton pregnant women who received treatment in our hospital from March 2021 to May 2022 were analyzed. All pregnant women were given fetal heart monitoring during delivery and then divided into control group and experimental group, with 40 cases in each group. All fetuses underwent umbilical artery blood gas analysis after delivery. Neonatal asphyxia, fetal distress, cesarean section, acidosis and forceps were compared between the two groups.
Results There was no significant difference in the ratio of amniotic fluid pollution Ⅰ° and Ⅱ° between the two groups, but the ratio of Ⅲ° in the experimental group was higher than that in the control group (P<0.05). There were no significant differences in cesarean section, forceps and death rates between 2 groups (P>0.05). There were no significant differences in VD, LD and VD+LD ratio of perinatal infants between the two groups (P>0.05). There were no significant differences in Apgar scores of 0-3, 4-7 and 8-10 between the two groups (P>0.05). PO2 and PCO2 of the experimental group were higher than those of the control group (P<0.05), pH and BE of the experimental group were lower than those of the control group (P<0.05), and acidosis was significantly higher than that of the control group (P<0.05).
Conclusion   For perinatal infants with abnormal umbilical cord, fetal heart monitoring combined with blood gas analysis can effectively detect fetal hypoxia and ischemia, and also reduce the rate of neonatal asphyxia and fetal distress. The clinical survival rate of fetal is relatively high, and the clinical use value is great.
