联合镇痛分娩的临床观察

目的 评价氧化亚氮吸人联合次髎穴、子宫穴注射利多卡因与单独治疗方法分娩镇痛的效果及对母儿的影响.方法 将400例产妇随机均分为四组,每组100例,产程活跃期给药实施分娩镇痛.观察组予50％氧化亚氮吸入,联合次髎穴、子宫穴注射利多卡因；对照组1给予50％氧化亚氮加50％氧气的混和气体吸入；对照组2给予次髎穴、子宫穴注射利多卡因；对照组3按产科常规分娩,不采取任何镇痛措施.分别观察镇痛效果、产程时间、分娩方式、新生儿情况、出血量情况.结果 观察组与3个对照组的镇痛效果(x2 =48.513)、产程时间(F =782.88、1120.81、1104.57)、分娩方式(x2=85.715),出血量(F=422.66)比较,差异均有统计学意义(均P＜0.05).结论 联合镇痛可明显减轻分娩时的痛苦,缩短产程,增加经阴道分娩率,减少剖宫产率,减少出血量,比使用单一镇痛方法有效.

Clinical observation of jiont analyesia in labor

Objective To evaluate the effect of nitrous oxide-inhale combined with lidocaine-injection by Ciliao and Uterine points and single therapy in labor analgesia, and the impact on maternal and child. Methods 400 cases were randomly divided into four groups. Observation group：100 cases take the therapy of Nitrous oxide-inhale combined with lidocaine-injection in Ciliao and Uterine points in the time of active period. Control group 1 ： 100 cases take the therapy of gas mixture-inhale （50% Nitrous oxide and 50% Oxygen） in the time of active period. Control group 2 ： 10（3 cases take the therapy of lidocaine-injection in Ciliao and Uterine points in the time of active period. Control group 3 ： 100 cases do not take any analgesia. Analgesic effects,labor time, mode of delivery, neonatal conditions, the amount of bleeding in every group were observed. Results There was statistically significant differences between the observation group with the control group 1,2,3 on analgesic effects （x2 = 48.513, P 〈 0.05 ） labor time （F = 782.88, 1120.81,1 1104.57, all P 〈 0.05 ）, mode of delivery （ X2 = 85. 715, P 〈 0.05 ）, neonatal conditions, the amount of bleeding（ F = 422.66, P 〈 0.05 ）. Conclusion Combination therapy was more effective than the single treatment.
