安桃乐与导乐分娩在分娩镇痛中的临床对比研究

Clinical Comparative Study on Labor Pain Relief by Doula and Patient-controlled Inhalation of Entonox

目的对比研究自控式安桃乐吸入法及导乐式分娩在分娩镇痛中的临床效果。方法120名产妇分为4组:自控式安桃乐吸入同时辅以导乐分娩组(A组)、自控式安桃乐吸入组(B组)、单纯导乐分娩组(C组)、空白对照组(D组),每组各30例,观察各组产痛的缓解程度、产程时间、分娩方式、产妇血氧饱和度、产后出血量、新生儿阿氏评分及副反应。结果镇痛满意率及有效率:A组(83.33%,96.67%)、B组(76.67%,90.00%)之间差异无显著性意义(P>0.05),A组及B组高于C(0.00%,6.67%)、D(0.00%,0.00%)两组(P<0.05);产程时间:A、B组为(219.23±72.65)min,C、D组为(302.83±98.77)min,A、B组较C、D组明显缩短(P<0.05);副反应、分娩方式、产后出血量、新生儿窒息率等指标4组比较差异无显著性意义(P>0.05)。结论自控式安桃乐吸入用于分娩镇痛在提高镇痛效果、缩短产程时间、减轻母婴影响方面优于导乐分娩,两种方法合用有利于提高围产期服务质量。

Objective To study the clinical comparison between the inhalation of Entonox （a kind of gas mixed with 50% nitrous oxide and 50% oxygen） and Doula on labor analgesia. Methods One hundred and twenty women with same labor conditions were divided into 4 groups. During labor, Group A inhaled Entonox matching plus Doula~ Group B inhaled Entonox; Group C deployed Doula only, Group D deployed routine method as control group. Four groups were compared with the followings： efficiency of relieving labor pain, time of labor duration, labor mode,bleeding during labor,side-effect and Apgar score. Results Satisfaction rate and effect rate of Group A （83.33%,96.67%） and Group B（76.67%, 90.00% ） were higher than that of other two groups. The time of labor duration of Group A and B[（219.23±72. 65）min]was shorter than that of Group C and D [（302. 83± 98. 77） min]. There was no significant difference between Group A and Group B. There was also no significant difference in labor mode, labor duration, bleeding during labor, side-effect and Apgar score between four groups （P〉O. 05）. Conclusion The controlled inhalation of Entonox is safe,which can depress labor pain, shorten duration of labor. There is no severe effect on both mother and infant. The controlled inhalation of Entonox matching Doula can enhance the quality of service during peripartum.
