摘要
①目的 探讨在产程活跃期笑气阶段性吸入对分娩镇痛的疗效及对母儿的影响。②方法 选择自愿在宫口开大 3cm时应用笑气吸入进行分娩镇痛的产妇 30 0例为观察组 ,另选择未行分娩镇痛的产妇 30 0例为对照组 ,观察比较两组产妇的产痛程度、产程时间、分娩方式 ,产后 2h内出血量、胎儿宫内窘迫发生率及新生儿窒息率。③结果 观察组笑气镇痛有效率、产程活跃期及总产程、经阴分娩率、胎儿宫内窘迫率与对照组比较 ,差异均有极显著性 (χ2 =4 .13～ 4 3.0 5 ;u =11.87、13.75 ;P <0 .0 1) ;产后 2h内出血量及新生儿Apgar评分两组比较差异无显著性 (u =1.88,χ2 =0 .4 3,P >0 .0 5 ) ;观察组产妇未出现严重不良反应。④结论 笑气阶段性吸入是一种有效、安全、操作简单的分娩镇痛方法 。
Objective To study the efficacy of intermittent inhalation of nitrous oxide for relieving pain during birth process and its influence on mothers and fetus. Methods Three hundred lying-in women willing to accept labor analgesia were selected as Observation Group and another 300 served as the Control Group .The painful extent, labor duration, labor pattern, the volume of postpartum hemorrhage in the first two hours, fetal distress rate and fetal suffocation rate were compared between the two groups. Results The difference between the two groups was statistically significant in terms of efficacy of analgesia, the duration of active stage and total stages of labor, the rate of transvaginal delivery and fetal distress(χ 2=4.13-43.05, u=11.87, 13.75, P< 0.01). No significant difference was found between the two groups in terms of the volume of postpartum hemorrhage and Apgar score (u=1.88, χ 2=0.43, P>0.05). No poor reaction was recorded in Observation Group. Conclusion Intermittent inhalation of nitrous oxide is an effective and safe way of analgesia for delivery, which is worth while to be recommended clinically.
