罗哌卡因配伍芬太尼分娩镇痛对产程和母儿预后的影响

目的 观察罗哌卡因卡配伍芬太尼用于分娩镇痛对产程和母儿预后的影响.方法 回顾性分析2006年1月.2007年9月在南方医科大学华瑞医院分娩的281例初产妇,其中接受0.15%罗哌卡因 芬太尼(1μg/ml)硬膜外镇痛的106例产妇为镇痛组,条件相似未行镇痛的175例产妇为对照组.记录两组活跃期时间、各产程时间、分娩方式、产程中处理方式、各组中发生产后出血、胎窘和新生儿窒息的例数.采用视觉模拟评分(VAS)评估宫缩时疼痛,改良Bromage评分评估下肢运动阻滞.结果 第一产程、第三产程和总产程时间两组间无差别.镇痛组第二产程延长、阴道顺产率和阴道助产率均高于对照组,活跃期更快、活跃期异常病例减少,催产素使用率高于对照组,新生儿窒息率增加.镇痛满意率达93.4%.结论 罗哌卡因配伍芬太尼镇痛分娩可降低剖宫产率,合理应用催产素可缩短活跃期,减少活跃期异常病例;注意加强第二产程的观察和处理,增加阴道手术助产、提高助产技术.

Influence of epidural ropivacaine in combination with fentanyl for labor analgesia on the clinical outcome of labor

OBJECTIVE: To investigate the effect of epidural ropivacaine in combination with fentanyl for labor analgesia on the clinical outcome of labor. METHODS: A retrospective study was conducted involving 281 healthy primiparas, including 106 undergoing spontaneous labor who received epidural 0.15% ropivacaine in combination with fentany (1microg/ml) and 175 without epidural analgesia. The active phase duration, durations of each labor stages, delivery modes, management of labor, postpartum hemorrhage, incidence of fetal distress and asphyxia neonatorum were recorded in the two groups. The visual analogue scale (VAS) was used to assess the pain of uterine contraction, and modified Bromage scoring system applied to evaluate the lower limb motor block. RESULTS: There were no significant differences in the duration of the first, third or the total labor stages between the two groups, but the second labor stage was prolonged in the labor analgesia group. The ratio of spontaneous labor, assisted vaginal delivery, and incidence of asphyxia neonatorum were higher, whereas the duration of the active stage was shortened in the analgesia group. CONCLUSION: Epidural ropivacaine in combination with fentanyl in labor can decrease the incidence of cesarean section, and the duration of the active stage can be shortened with application of ocytocin.
