摘　　要：目的比较自由体位与仰卧位分娩对产程进展及分娩结局的影响。方法选取2019年7月至2022年7月安徽省蚌埠市第三人民医院待产的100例产妇,按照随机数字表法将其分为仰卧位组和自由体位组,每组50例。仰卧位组第一产程采用仰卧位,至宫口全开;第二产程采用膀胱截石位;自由体位组第一与第二产程均由产妇根据自身舒适度和喜好选择体位。比较两组第一、二、三产程,产后2 h出血量;采用麦吉尔疼痛问卷表评估两组分娩疼痛情况,包括疼痛分级指数(PRI)、现有疼痛强度(PPI)、目测类比定级法(VAS);比较分娩结局。结果自由体位组第一、二、三产程短于仰卧位组,产后2 h出血量少于仰卧位组(P<0.05)。自由体位组PRI、PPI、VAS评分低于仰卧位组(P<0.05)。两组产程停滞、新生儿窒息、产后出血比较,差异无统计学意义(P>0.05)。自由体位组宫缩乏力、软产道裂伤发生率低于仰卧位组(P<0.05)。结论自由体位分娩有利于缩短产妇产程,减轻分娩疼痛,改善分娩结局。Objective To compare the effect of free position and supine position on labor progress and delivery outcome.Methods A total of 100 parturients were selected from the Third People’s Hospital of Bengbu,Anhui Province from July 2019 to July 2022 were selected.They were divided into supine position group and free position group according to random number table method,with 50 cases in each group.In supine position group,the first stage of labor was supine,until the uterine orifice was fully opened;and the second stage of labor was lithotomy of bladder.In free position group,the first and second stages of labor were selected by the parturients according to their own comfort and preferences.The first,second,and third stage of labor,2 h postpartum blood loss were compared between two groups;labor pain was evaluated by McGill pain questionnaire,including pain rating index(PRI),present pain intensity(PPI),visual analogue scale(VAS);the labor outcome was compared.Results The first,second,and third stages of labor in the free position group were shorter than those in the supine position group,the 2 h postpartum blood loss was less than that in the supine position group(P<0.05).The scores of PRI,PPI,and VAS in the free position group were lower than those in the supine position group(P<0.05).There were no significant differences in labor stagnation,neonatal asphyxia,and postpartum hemorrhage between the two groups(P>0.05).The incidence of uterine weakness and soft birth canal laceration in the free position group were lower than those in the supine position group(P<0.05).Conclusion Free position delivery is beneficial to shorten maternal labor,reduce labor pain,and improve labor outcome.
