摘要
目的:探讨头位分娩时应用气囊扩张阴道术加笑气镇痛的有效性与安全性。方法:将120例单胎头位足月初产妇分为两组,在产程中用气囊扩张阴道术并同时吸入笑气(50%氧化亚氮与50%氧气的混合气体)实施分娩镇痛者60例(观察组);对照组60例,产程中间断吸入氧气,不用任何镇痛药物。观察两组产妇的产痛程度、产程时间、分娩方式、产后出血量、新生儿出生时Apgar评分及笑气吸入的副反应等。结果:气囊扩张术加笑气镇痛的产妇镇痛分级:0级14例,Ⅰ级42例,有效率为93.3%,与对照组比较,差异有显著性意义(P<0.05);观察组总产程时间为8.3h,第一产程为7.2h,第二产程为52.1min,明显短于对照组,具有显著性差异(P<0.05);观察组剖宫产率明显低于对照组,差异有显著性(P<0.05),阴道助产率、产后出血量及新生儿Apgar评分比较,两组无显著性差异(P>0.05)。结论:头位分娩时应用气囊扩张阴道术加笑气镇痛安全方便,易被产妇接受,可有效促进产程进展,缓解分娩疼痛,增加自然分娩率,降低剖宫产率,对母儿无不良影响。
Objective： To investigate the efficacy and safety of vaginal balloon dilatation and labor analgesia with inhalation of 50% nitrous oxide in oxygen. Methods： A total of 120 cases of term primiparous women in labor were divided into two groups： study group （n = 60） used vaginal balloon dilatation to dilate the vaginal and same time 50% nitrous oxide in oxygen was inhalated during labor for relieving labor pain, control group （n =60） intermittent inhalation of oxygen was carried out during labor. Two groups were compared with following indices ： duration of the labor, delivery mode, meconium stained of amniotic fluid, postpartum bleeding volume, neonatal Apgar score, and side effect of nitrous oxide. Results： The efficiency of relieving labor pain in study group was much better than that of control group （ P 〈 0. 05 ） . The length of first stage, second stage and the length of labor when the vaginal balloon dilatation were used in active phase were shorter than those in control group （ P 〈 0. 05 ） . Rate of cesarean section in study group was lower than that of control group （ P 〈 0.05 ） ~ There were no significant differences in meconium stained amniotic fluid, postpartum bleeding volume, and neonatal Apgar score between two groups （ P 〉 0. 05 ） . Conclusion： The application of the vaginal balloon dilatation and inhalation of 50% nitrous oxide in oxygen is convenient and safe during labor. The measure is useful in relieving labor pain, accelerating labor course, lowering cesarean section rate without any side effect on mother and baby.
