摘要目的 分析研究设计的一种用于辅助手膝位,避免体力消耗,增加舒适感的分娩球组架的临床效果.方法 将产程中发生枕横(后)位初产妇260例,按住院顺序法随机等分为观察组和对照组各130例.观察组产妇伏于装置的瑜伽球上,根据产妇体型调节机架和球盘角度和高度,使胸部和跨部的瑜伽球可以有效支撑产妇体质量减轻膝盖负担,两侧腹部小瑜伽球能有效贴合.调整完成后嘱产妇放松轻轻沿一个方向晃动身体使腹侧部小瑜伽球形成持续舒缓的推挤.对照组双膝着地(戴上护具)身体向前倾屈,双手掌或双拳着地支撑自己,摇摆骨盆或向前爬行.对比2组的经阴道分娩率、产妇体位维持时间、产妇分娩体验、有效纠正率.结果 观察组体位维持时间为(49.51±10.62) min,对照组为(18.31±9.72) min,2组比较差异有统计学意义(t=6.69,P＜0.05);观察组胎位异常有效纠正率、顺产率、舒适率分别为82.30％(107/130)、77.69％(101/130)、99.23％(129/130),对照组分别为27.69％(36/130)、33.85％(44/130)、3.84％(5/130),2组比较差异有统计学意义(x2=4.06、4.15、5.61,均P＜0.05).结论 本科设计的这种分娩球组架可以有效辅助行手膝体位,减轻体力消耗,增加产妇舒适感,对帮助体位外转胎位有显著的作用.

abstractsObjective To analyze the clinical effect of a bifurcated ball frame designed for undergraduate research to assist hand-knee position,avoid physical exertion and increase comfort.Methods Randomized controlled trials consisted of 260 occipital (posterior) primiparous women born during labor,and were randomly divided into the observation group and the control group with 130 cases each.The observing group's mothers were on the yoga ball on the device.The angle and height of the frame and the ball plate were adjusted according to the maternal body type,so that the yoga ball at the chest and the cross could effectively support the maternal weight loss knee burden,and both sides of the small abdominal yoga ball could be effectively posted.After the adjustment was completed,the maternal relaxes and gently shakes the body in one direction so that the small yoga ball on the ventral side forms a continuous soothing push.The control group leaned forward on both knees (with protective gear) and supported themselves with both hands or both fists,swaying the pelvis or crawling forward.Comparing the two groups of vaginal delivery rate,maternal postural maintenance time,maternal dehvery experience,and effective correction rate of occipital position.Results The time of postoperative maintenance in the observation group was (49.51 ±10.62) minutes,and that of the control group was (18.31 ± 9.72) minutes.The difference between the two groups was statistically significant (t=6.69,P ＜0.05).The effective correction of abnormal fetal position rate,spontaneous delivery rate and comfort rate were 82.30％ (107/130),77.69％ (101/130),and 99.23％ (129/130),respectively in the observation group,and 27.69％ (36/130),33.85％ (44/130),3.84％ (5/130),respectively in the control group,the differences between the two groups were statistically significant (x2 =4.06,4.15,5.61,all P ＜0.05).Conclusions The undergraduate design of this sort of ball delivery group has a significant effect on the extraversion of the assisted position to the fetal position.
