活跃期导乐仪联合分娩球纠正枕后位的效果分析

Study on the effect of the active phase of Doula delivery ball apparatus combined with correct occipitoposterior

目的 探讨导乐仪联合分娩球纠正枕后位的效果.方法 选择宫口开大3 cm,胎方位为枕后位的初产妇400例,根据产妇意愿分为观察组及对照组,每组200例.观察组应用导乐仪联合分娩球助产,对照组选择自由体位、传统分娩模式.比较两组阴道分娩率、疼痛程度、产后2h出血量、新生儿窒息率的差异.结果 观察组疼痛发生程度Ⅲ级4.0％ (8/200)低于对照组50.0％ (100/200),差异有统计意义(x2=11.55,P＜0.01);观察组阴道自然分娩率84.5％(169/200)高于对照组60.5％(121/200),差异有统计学意义(x2=28.905,P=0.001);产后2h出血量(156.3±53.2) ml低于对照组(268.1±54.6)ml(t=20.70,P＜0.01);产后出血率0.5％(1/200)低于对照组4.0％ (8/200),差异有统计学意义(P=0.018).结论 导乐仪联合分娩球应用于第一产程活跃期可安全有效缓解产痛、促进自然分娩.

Objective To investigate the effect of Doula delivery ball apparatus combined with correct occipitoposterior.Methods Four hundred primiparas whose dilatation of cervix of 3 cm and position of foetus was occipitopostenor position, were randomly divided into observation group and control group according their wishes, and each group of 200 cases.Doula delivery ball was used for the observation group,while the free body position, the traditional delivery mode was the control group.The vaginal delivery rate, degree of pain, postpartum 2 h bleeding volume and neonatal asphyxia rate were compared between the two groups.Results The degree of pain Ⅲ degree was 4.0％ (8/200) ,lower than the control group(50.0％ (100/200), x2 =11.55,P＜0.01).The vaginal delivery rate in observation group was 84.5％ (169/200), higher than that in control group (60.5％ (121/200);x2 =28.905,P=0.001).Postpartum 2H bleeding was (156.3±53.2) ml, lower than the control group((268.1±54.6) ml, t =20.70, P＜0.01).The Postpartum bleeding rate was 0.5％ (1/200), lower than that in control group (4.0％ (8/200) ,P =0.018).Conclusion Doula delivery ball is applied to the first active stage of labor can effectively relieve pain, promote the safety of natural childbirth.
