摘　　要：目的探讨枕后位和枕横位产妇采用自由体位进行分娩对产程的影响。方法按照随机数字表法将2011年1月至2014年1月三门县人民医院收治的枕后位和枕横位产妇分为两组,观察组采用自由体位分娩,对照组采用截石位分娩,比较两组的产程时间以及分娩结局。结果观察组第一、二产程和总产程时间均小于对照组,差异有统计学意义(t值分别为6.831、3.178、4.057,均P<0.05),两组第三产程时间比较,差异无统计学意义(t=1.531,P>0.05)。观察组经阴道顺产率(88.78%)高于对照组(64.65%),差异有统计学意义(x^2=16.020,P<0.01)。观察组产后出血率、新生儿窒息率均低于对照组,差异有统计学意义(t值分别为8.611、3.960,均P<0.05)。结论枕后位和枕横位产妇在分娩中采用自由体位进行分娩具有加快产程、减少剖宫产和阴道助产率、更有利于母婴健康的特点,临床有重要参考价值。Objective To investigate the effect of free posture on birth process in puerpera with occiput posterior position and occipito transverse position.Methods Cases with occiput posterior position and occipito transverse position admitted in People＇s Hospital of Sanmen County in Zhejiang Province from January 2011 to January 2014 were divided into two groups according to random number table method, observation group adopting free posture for delivery and control group using lithotomy position for childbirth.The labor time and delivery outcomes of two groups were compared.Results The first and second stage time and total stage time of birth process in the observation group were less than those in the control group, and the differences were statistically significant （ t value was 6.831, 3.178 and 4.057, respectively, all P〈0.05）.But there was no significant difference in the third stage time of labor between two groups （t=1.531,P〉0.05）.The vaginal delivery rate in the observation group （88.78%） was higher than that in the control group （64.65%）, and the difference was significant （χ^2 =16.020,P〈0.01）.The rates of postpartum hemorrhage and neonatal asphyxia in the observation group were less than those in the control group, and the differences were significant （ t value was 8.611 and 3.960, respectively, both P〈0.05）.Conclusion Free posture for cases with occiput posterior position and occipito transverse position during delivery has characteristics of speeding up birth process, reducing cesarean section rate and vaginal delivery rate, which is good for maternal and child health and it has very important clinical reference value.
