摘　　要：目的探讨可行走式分娩镇痛对胎儿血氧饱和度的影响。方法选取60例足月待产病例,其中30例行罗哌卡因+舒芬太尼复合的腰硬联合镇痛即可行走式分娩镇痛,30例自然分娩组产程中不使用任何药物镇痛。在活跃期进行胎儿血氧饱和度的监护,记录第一产程活跃期、第二产程胎儿血氧饱和度值及胎儿血氧饱和度最低值。胎儿出生后立即抽取脐动脉血进行血脐分析,记录pH值和BE值。结果可行走式分娩镇痛组和自然分娩组比较:第一产程活跃期胎儿血氧饱和度分别为(51.92±5.90)%和(50.77±6.47)%(P=0.48),第二产程胎儿血氧饱和度分别为(44.85±6.27)%和(43.12±7.34)%(P=0.32);胎儿血氧饱和度最低值分别为(41.63±7.51)%和(40.96±7.48)%(P=0.73)。结论可行走式分娩镇痛对产程中胎儿血氧饱和度无影响。Objective To observe the effect of ambulatory labor analgesia on fetal oxygen saturation during labor. Methods Sixty parturients with uncomplicated term pregnancies were equally divided, according to their personal preference, into ambulatory analgesia group receiving combined spinal-epidural labor analgesia and control group without analgesia administration. All the parturients with ambulatory labor analgesia received sufentanil and ropivacaine administration. Fetal oxygen saturation was monitored continuously during the labor by recording the values every 5 minutes and the mean value was calculated. Umbilical blood was analyzed aider fetal delivery and the pH, base excess （BE） value were recorded. Results In the analgesia group and the control group, the mean values of fetal oxygen saturation was （51.92±5.90） % and （50.77±6.47） %, respectively, during the first labor stage （P=0.48）, and was （44.85±6.27） % and （43.12±7.34） % during the second labor stage （P=0.32）, and the lowest values during the labor was （41.63±7.51 ） % and （40.96±7.48） %, respectively （P=0.73）, showing no significant differences in the three values between the two groups. Conclusion Ambulatory labor analgesia does not significantly affect fetal oxygen saturation during the entire course of labor.
