椎管内分娩镇痛对足月初产妇产程进展及分娩结局的影响

Effects of Spinal Canal Analgesia on Maternity Progression and Delivery Outcomes in Term Primipara

目的探讨椎管内分娩镇痛对足月初产妇产程进展及分娩结局的影响效果。方法选择2018年7月-2019年6月该院收治的720例足月初产妇,根据患者是否接受了椎管内分娩镇痛将其分为对照组和观察组各360例,观察组产妇未接受椎管内分娩镇痛,观察组产妇接受了椎管内分娩镇痛,观察对比两组产妇的分娩方式、生产时发热情况和术后出血情况、产程时间。结果观察组产妇中经阴道分娩的比例为94.72%(341/360)与对照组产妇的91.94%(331/360)差异无统计学意义(χ^2=0.620,P>0.05),观察组产妇的产后出血率与对照组的产后出血率相比差异无统计学意义(χ^2=0.439,P>0.05),观察组产妇的第三产程与对照组差异无统计学意义(t=0.000,P>0.05);观察组产妇在生产时发热率为11.11%(40/360)要高于对照组产妇的2.77%(10/360)(χ^2=5.373),观察组产妇的第一产程和第二产程都要高于对照组(t=3.651、9.172),观察组患者在术后2 h的出血量要大于对照组,差异有统计学意义(t=0.908,P<0.05)。结论分娩镇痛对足月初产妇的第一产程和第二产程会有所延长,但对于第三产程不产生影响,会提高在分娩过程中发热的概率,对于产后出血、分娩方式没有明显的影响。

Objective To investigate the effects of analgesia during spinal canal delivery on labor progression and delivery outcomes in term primiparas.Methods A total of 720 full-term early-term pregnant women admitted to the hospital from July 2018 to June 2019 were selected.The patients were divided into a control group and an observation group with 360 cases each according to whether they received intraspinal delivery analgesia.The control group with spinal canal delivery analgesia,the observation group women received spinal canal delivery analgesia.Observed and compared the two groups’delivery methods,fever during delivery,postoperative bleeding,and labor time.Results The percentage of vaginal delivery in the observation group was 94.72%(341/360)and 91.94%(331/360)in the control group.There was no statistically significant difference(χ^2=0.620,P>0.05).The postpartum hemorrhage rate of the observation group was similar to that of the control group.There was no statistically significant difference in postpartum hemorrhage rate(χ^2=0.439,P>0.05).The third stage of labor in the observation group was no statistically significantly different from that in the control group(t=0.000,P>0.05).The difference between the two groups was no statistically significant(P>0.05);in the observation group,the febrile fever rate during delivery was 11.11%(40/360),which was higher than that of the control group’s 2.77%(10/360)(χ^2=5.373).Compared with the control group(t=3.651,9.172),the amount of bleeding in the observation group was greater than that in the control group at 2 h(t=0.908,P<0.05),the results of the two groups were statistically significantly different,.Conclusion Labor analgesia will prolong the first and second stages of labor at term,but it has no effect on the third stage of labor,it will increase the probability of fever during childbirth,and has no obvious effect on postpartum hemorrhage and delivery methods.
