摘要
目的比较病人自控硬膜外镇痛(PCEA)与氧化亚氮吸入用于分娩镇痛的临床效果。方法阴道分娩单胎初产妇360例,随机均分成三组。当宫口开至3cm时,P组应用0.11%罗哌卡因和2μg/ml芬太尼混合液PCEA,N组应用氧化亚氮吸入(50%氧化亚氮和50%的氧气)镇痛,C组为对照组,无镇痛干预。结果两种镇痛方法均能提供安全有效的分娩镇痛,产程时间缩短,剖宫率显著下降,阴道助产率无增加,对胎儿和新生儿无不良影响,产后出血不增加,所有产妇都能下床活动。P组活跃期(129±42)min,短于N组的(169±44)min(P<0.05)。结论与氧化亚氮分娩镇痛相比,PCEA效果更确切,产程更加缩短,更适合于分娩镇痛。
Objective To compare the clinical effects of patient-controlled epidural analgesia （PCEA） or nitrous oxide inhalation analgesia. Methods A total of 360 single-fetal primiparas of vagina-deliverying were randomly divided into three groups with 120 cases each. When utero-cervieal was opened about 3 cm, the patients in group P were given PCEA with 2 μg/ml fentany and 0. 11 ropivaeaine and those in group N received inhalation of 50% nitrous oxide in 50% oxygen. Results A satisfeetory delivery analgesia was obtained in both groups with shortened labor process, decreased rate of cesarean section or instrument labor and side effects on the fetal and neonate, without increase of postpartum hemorrhage. All the primiparas could take off-bed activity. The active phase of group P was （129±42） rain, which was shorter than（169±44） rain in group N（P〈0. 05）. Conclusion Compared with nitrous oxide inhalation,PeEA is more effect and suitable for labor analgesia.
