目的:探讨不同腰硬联合镇痛用药时机对无痛分娩产程的影响。方法:选取在我院行无痛分娩的88例产妇作为观察组,根据腰硬联合镇痛用药时间的不同,又将其分为Ⅰ组(40例)和Ⅱ组(48例),另选取同期在我院进行常规阴道分娩的50例产妇作为对照组,比较观察组各组的镇痛效果及三组的产程情况。结果:Ⅰ组和Ⅱ组的镇痛总有效率均达到了100.0%,组间比较无显著性差异(P>0.05);Ⅰ、Ⅱ两组的活跃期、第一产程时间均显著短于对照组(P<0.0),活跃期宫口扩张速度明显比对照组更快(P<0.05);Ⅰ组的第二产程显著短于Ⅱ组(P<0.05),但与对照组比较无显著性差异(P>0.05)。结论:在分娩过程中应用腰硬联合镇痛可有效缩短活跃期时间,加快宫口扩张速度,缩短第一产程,在宫口扩张到8cm时停止给药,可有效缩短第二产程。
Objective: To explore the effect of different spinal and epidural analgesics on the labor process of painless labor. Methods: Eighty-eight maternal women with painless delivery in our hospital were selected as the observation group. According to the different time of analgesia combined with spinal-epidural analgesia, they were divided into group I (n = 40) and group II (n = 48) During the same period in our hospital routine vaginal delivery of 50 cases of maternal as a control group, the observation group compared analgesic effect of each group and labor status of the three groups. Results: The total effective rate of group Ⅰ and group Ⅱ reached 100.0%, there was no significant difference between the two groups (P> 0.05). The active phase and the first stage of labor in Ⅰ and Ⅱ groups were significantly shorter than those in control group (P <0.05). The rate of dilatation of cervix in active phase was significantly faster than that in control group (P <0.05). The second stage of labor in group I was significantly shorter than that in group II (P <0.05), but no significant difference compared with control group Difference (P> 0.05). Conclusion: The application of combined spinal and epidural analgesia in delivery can effectively shorten the active period, speed up the expansion of the cervix and shorten the first stage of labor. When the cervix is dilated to 8 cm, administration is stopped and the second stage of labor can be effectively shortened.
