ABSTRACT
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.
