Abstract：Objective To investigate the effect of free posture and traditional position of primipara during the second stage of painless labor on pregnancy outcomes. Methods A total of 120 primiparas were randomly divided into the free group and the traditional group, with 60 cases in each group. The prenatal intervention of the two groups was the same, and they were given spinal anesthesia of painless labor. When entering the second stage of labor, the traditional group adopted the traditional supine before delivery while the free group adopted free position. Comparisons were made between the two groups in terms of labor process, pregnancy outcome, complications, postpartum subjective pain and sense of delivery control. Results The second stage of labor in the free group was significantly shorter than that in the traditional group (P<0.05), and the incidence of abnormal fetal heart rate in the second stage of labor was significantly lower than that in the traditional group. The improvement time of abnormal fetal heart rate was significantly shorter than that in the traditional group (P<0.05). The natural delivery rate of primipara in the free group was significantly higher than that in the traditional group, and the transit cesarean section rate was significantly lower than that in the traditional group (P<0.05). Compared to the traditional group, the incidences of lateral perineal excision, postpartum discomfort, tension urinary incontinence and neonatal asphyxia were significantly lower in the free group (P<0.05). The pain visual analogue scale (VAS) score of subjective delivery in the free group was significantly lower than that in the traditional group, and the parturition control (LAS) score was significantly higher than that in the traditional group (P<0.05). Conclusion Compared to the traditional position, the free posture during the second stage of primipara painless labor can shorten the labor time, improve the rate of natural delivery and reduce maternal and neonatal complications. Thus, it can further reduce labor pain and improve parturition control.
