摘　　要：目的 了解腰麻—硬膜外联合阻滞镇痛 (CSEA)用于分娩镇痛时对宫颈扩张速率的影响。 方法100例单胎、头位、足月、无产科合并症及并发症的初产妇在宫口3～4cm时随机分为CSEA组 (行CSEA分娩镇痛 )和未镇痛组 (未予镇痛处理 ) ,观察宫颈扩张速率、产程进展、分娩结局及新生儿情况。 结果 两组入选前宫颈扩张速率无差异 (P>0.05) ,入选后CSEA组宫颈扩张速率明显高于未镇痛组 (P<0.05) ;CSEA组第二产程较未镇痛组长 ,但均在2h以内 ;两组的分娩结局及新生儿情况无区别 (P>0.05)。 结论 健康初产妇行CSEA分娩镇痛能增加宫颈扩张速率 ,但延缓第二产程进展。Objective To assess the influence of combined spinal-epidural analgesia(CSEA)used in labor analgesia on the speed of the cervical dilation.Methods One hundred healthy nulliparous parturients in spontaneous labor with singleton,vertex,full-term fetuses were enrolled in a double-blinded trial when their cervical dilation was in3-4cm.The patients were randomly assigned to CSEA group(receive CSEA labor analgesia)and non-analgesia group(receive no labor analgesia).Data were collected on cervical dilation,labor progress,outcome of labor and neonate status.Results The speed of cervical dilation was no difference between groups before enrollment(P>0.05),CSEA group was faster in cervical dilation than non-analgesia group after enrollment(P<0.05).The second stage of labor progress in CSEA group was longer than non-analgesia group,but the time was within2hours.The outcome of labor and the neonate status were not different between two groups(P>0.05).Conclusion CSEA used in labor analgesia of healthy nulliparous parturients can inˉcrease the speed of cervical dilation,but may delay the second stage of labor progress.
