摘    要:目的 比较椎管内阻滞麻醉和笑气吸入两种方法的分娩镇痛效果和对产妇及新生儿的影响。方法 随机选取 30 0例产妇分为笑气组、椎管内阻滞组和对照组 ,每组各 10 0例。在分娩过程中 ,笑气组给予吸入含 5 0 %笑气与 5 0 %氧气的混合气体 ;椎管内阻滞组给予蛛网膜下腔 +硬膜外腔联合注入芬太尼和布比卡因 ;对照组未给予镇痛药物。并分别观察 3组产妇的镇痛效果、产程时间、分娩方式、产后出血量、产妇桡动脉血及新生儿脐血的血气分析以及新生儿窒息情况。结果  (1)镇痛效果比较 :椎管内阻滞组镇痛分级 0级为 88例 ,笑气组为 12例 ,对照组为 0例。 3组之间比较 ,差异有极显著性 (P <0 0 1)。 (2 )产程时间比较 :第一产程和总产程时间 ,椎管内阻滞组短于对照组和笑气组 (P <0 0 5 ) ,笑气组与对照组比较 ,差异无显著性 (P >0 0 5 ) ;第二产程时间椎管内阻滞组长于对照组和笑气组 ,但差异无显著性 (P >0 0 5 )。 (3)剖宫产术后出血量比较 :笑气组为 (373± 77)ml,椎管内阻滞组为 (2 5 9± 78)ml,对照组为 (2 39± 89)ml,笑气组与其他两组比较 ,差异有极显著性 (P<0 0 1)。(4)血气分析结果比较 :3组产妇桡动脉血及新生儿脐血血气分析结果各组之间比较 ,差异均无显著性 (P >0 0 5 )。 (5 )分娩方式比较

Abstract:OBJECTIVE: To study the pain relief effectiveness of the combined spinal-epidural analgesia (CSEA) and the inhalation of nitrous oxide, and the influences on the mothers and infants. METHODS: The 300 cases of pregnant women were randomly divided into 3 groups: CSEA group, nitrous oxide group and control group. The nitrous oxide group was that pregnant women inhaled nitrous oxide premixed with oxygen (50%:50%), the pregnant women of the CSEA group were injected fentanyl and bupivacaine in the subarachnoid and epidural space, analgesic was not used in the control group. The degree of labor pain, duration of the labor, way of delivery, bleeding volume, rate of anoxia of newborn, blood gas analysis to maternal radius artery and fetal umbilical blood among 3 groups were observed. RESULTS: The effect for analgesia labor of the CSEA group was much better than that of the nitrous oxide group (P < 0.01). In the first stage of labor and total stage of labor, the CSEA group was shorter than the others (P < 0.05), but there was no difference between the nitrous oxide group and the control group (P > 0.05). In the second stage of labor, the 3 groups were alike to each other. The bleeding volume of caesarean section (373 +/- 77) ml in the nitrous oxide group was much more than the other 2 groups, there was no difference between the CSEA group (259 +/- 78) ml and the control group (239 +/- 89) ml. The rate of obstetric forceps of CSEA group was higher than the control group (P < 0.01), and the rate of caesarean section of the nitrous oxide group was much higher than the CSEA group. The blood gas analysis to maternal radius artery and fetal umbilical blood and the rate of anoxia of newborn of 3 groups revealed no significant difference. CONCLUSIONS: The effectiveness of the combined spinal-epidural analgesia CSEA for analgesia labor is confirmed and has rarely side-effect, and it can be the first choice, and the inhalation of nitrous oxide can safely provide effective labor analgesia, too.
