无痛分娩对初产妇产程及新生儿脐血血气指标的影响

Effect of Painless Delivery on the Labor Process of Primipara and Umbilical Blood Gas Index of Newborn

目的研究无痛分娩对初产妇产程及新生儿脐血血气指标的影响。方法以60例初产妇为研究对象,根据生育意愿将产妇分为无痛分娩组(n=27)和常规分娩组(n=33),无痛分娩组使用罗哌卡因+舒芬太尼镇痛,常规分娩组不使用镇痛。比较两组一般情况、疼痛情况、新生儿脐血血气指标、母婴结局。结果无痛分娩组产妇首次下床活动时间短于常规分娩组,第二产程、总产程长于常规分娩组,差异有统计学意义(P<0.05),两组第一产程、第三产程、住院时间比较差异无统计学意义(P>0.05);两组产妇分娩前后视觉模拟评分法(VAS)得分差异有统计学意义(P<0.05),无痛分娩组得分更低;两组新生儿动脉氧分压(PaO2)、碱剩余(BE)、酸碱度(pH)、乳酸比较差异无统计学意义(P>0.05);两组母婴结局比较差异无统计学意义(P>0.05)。结论无痛分娩有助于减缓初产妇分娩疼痛,促进尽早下床活动,对新生儿脐血血气指标影响较小,未明显导致母婴不良结局,但可延长产程。

Objective To study the effect of painless delivery on the labor process of primipara and umbilical blood gas index of newborn.Methods A total of 60 primiparas were selected as research objects.According to their fertility intention,the primiparas were divided into painless delivery group(n=27)and conventional delivery group(n=33).Ropivacaine and sufentanil were used for analgesia in the painless delivery group,while no analgesia was used in the conventional delivery group.The general condition,pain condition,umbilical blood gas index of newborn,maternal and infant outcome were compared between the two groups.Results The first time of getting out of bed in painless labor group was shorter than that in conventional labor group,and the second stage of labor and total stage of labor were longer than that in conventional labor group,the difference was statistically significant(P<0.05).There was no significant difference in the first stage of labor,the third stage of labor and the length of hospital stay between the two groups(P>0.05).There was statistically significant difference in VAS scores between the two groups before and after delivery(P<0.05),and painless delivery group scored lower.There was no significant difference in PaO2,BE,pH and lactic acid between the two groups(P>0.05).There was no significant difference in the maternal and infant outcomes between the two groups(P>0.05).Conclusions Painless delivery is helpful to alleviate the pain of primipara in labor,promote the activity of getting out of bed as soon as possible,and has little impact on the umbilical blood gas index of newborn.It does not significantly lead to adverse maternal and infant outcomes,but can prolong the labor process.
