硬膜外自控镇痛在分娩镇痛中的应用

Patient-controlled epidural analgesia in labor analgesia

目的:观察硬膜外自控镇痛(PCEA)用于分娩镇痛中的临床效果。方法:100例ASAⅠ-Ⅱ级单胎足月初产妇,随机分为两组,Ⅰ组采用PCEA法注入0.15%布比卡因+0016%芬太尼。锁定时间20min。Ⅱ组为对照组,只作产科常规处理。观察两组产妇产痛、产程、分娩方式、催产素使用率、新生儿Apgar评分度并发症情巩。结果:与对照组相比.镇痛组的产程活跃期明显缩短(p<0.05).镇痛效果佳(P<0.001),而剖宫产率、新生儿Apgar评分、尿潴留发生率、出血量无差异,但镇痛组的催产素使用率明显高于对照组(P<0.05)。结论:PCEA用于分娩镇痛效果肯定。

Objective To observe the clinical effect of patient-controlled epidural analgesia（PCEA） used in labor analgesia.Methods：100 cases of primipara,full term,single fetus with ASAⅠ-Ⅱ were randomly divided into two grups.Group Ⅰ were injected with 0.15% bupivacaine and 0.016% fentanyl using PCEA with lock time 20 minutes.Group Ⅱ was the control group which just be given conventional obstetrical treatment.Then,the labor pain,labor,mode of delivery,oxytocin usage,newborn Apgar＇s grading and occurrence of complications of these two grups parturients were observed.Results：Active phase of labor stage in analgesic group was significantly shorter compared with the control group（P〈0.05） and analgesic grup possessed good analgesic effect（P〈0.001）.No difference was found in the cesarean section rate,newborn Apgar＇s grading,incidence of urinary retention and blood loss between these two grups,whereas oxytocin usage in analgesic grup was significantly higher than that in control group（P〈0.05）.Conclusion：Patient-controlled epidural analgesia（PCEA） used in labor analgesia has a positive effect.
