产前电子胎心率变化(EFM)与产后新生儿酸血症的相关性研究

Study on the relationship between changes in prenatal electronic fetal monitoring and postpartum neonatal acidosis

目的研究产前电子胎心率变化(EFM)与产后新生儿酸血症的相关性。方法选取2017年10月至2018年3月深圳市蛇口人民医院诊治的160例胎儿电子监护图形异常的产妇作为研究组,以及胎儿电子监护图形正常的产妇160例作为对照组进行研究。观察两组产妇产前电子胎心率变化(EFM)、产后新生儿酸血症发生情况、新生儿阿氏评分、新生儿脐动脉血气指标比较以及产妇临床资料情况对比。结果研究组产妇在年龄、孕周以及新生儿重量方面与对照组产妇差异无统计学意义(P>0.05);对照组产妇产出的新生儿阿氏评分明显高于研究组产妇的新生儿,差异具有统计学意义(P<0.05);对照组新生儿其动脉血气指标中pH值、BE、PO_2以及SB水平显著高于研究组新生儿(P<0.05),而PCO_2水平明显低于研究组新生儿,差异具有统计学意义(P<0.05);对照组新生儿胎心率评分(FHR评分)明显高于研究组新生儿,差异具有统计学意义(P<0.05);对照组患者患者剖宫产以及胎吸助产比例明显低于研究组患者,差异具有统计学意义(P<0.05),自然分娩比例显著高于研究组者,差异具有统计学意义(P<0.05)。结论胎儿电子监护图形异常的产妇其胎心率评分明显较高,对后期治疗提供数据,值得在临床上进一步采用和推广。

Objective To study the correlation between changes in prenatal electronic fetal monitoring(EFM) and postpartum neonatal acidosis. Methods 160 parturients with abnormal EFM in our hospital fromOctober 2017 to March 2018 were selected as the study group and 160 pregnant women with normal EFM as the control group. The changes in the EFM, the occurrence of neonatal acidemia, newbornApgar score, neonatal umbilical artery blood gas index and maternal clinical datain the two groupswere observed and compared. Results There was no statistically significant difference between the two groups in the age, pregnancy week and the weight of newborn(P>0.05). The newborn Apgar scores in the control group were significantly higher than those in the study group, with statistically significant difference(P< 0.05). The levels of pH, BE, PO2 and SB in the blood gas index of the control group was significantly higher than those in the study group(P<0.05), while the level of PCO2 was significantly lower than that of the study group, all with statistically significant differences(P<0.05).The neonatal fetal heart rate score(FHR score) in the control group was significantly higher than that of the study group, with statistically significant difference(P<0.05). The proportion of caesarean section and fetal suction in the control group was significantly lower than that of the study group(P<0.05), and the ratio of natural birth ratio was significantly lower thanthat of the study group, all with statistically significant differences(P<0.05). Conclusions The FHR score of pregnant women with abnormal EFM is obviously higher, which is of significance for the treatment and can be used and popularized in clinical practice.
