目的探讨产程中改变产妇体位在枕后位及枕横位分娩中的效果。方法将82例活跃期为枕后位、枕横位足月妊娠健康产妇,随机分为改变体位组(观察组41例)和常规体位组(对照组41例),观察其分娩方式。结果观察组的阴道分娩率为82.9%,对照组的阴道分娩率为53.7%,两组比较,差异有统计学意义(P<0.05)。结论临产后改变产妇体位,可纠正持续性枕后位、枕横位,提高自然分娩率。 Objective To investigate the effect of changing the position of maternal body in the occiput posterior position and occipital transverse position in delivery. Methods Eighty-two healthy mothers of full-term pregnancy with suboccipital posterior position and occipital transverse direction were randomly divided into 4 groups: the modified position group (observation group) and the normal position group (41 patients). The mode of delivery was observed. Results The vaginal delivery rate was 82.9% in the observation group and 53.7% in the control group. There was significant difference between the two groups (P <0.05). Conclusions Postpartum changes in maternal position, can correct the persistent posterior position, occipital transverse position, improve the rate of natural delivery.
