Objective To investigate the impact of the implementation of free-position active at the stages of labor maternity outcomes. Methods The proposed transvaginal delivery primipara 220 cases were randomly divided into intervention group and control group,each of 110 patients, the control group used conventional supine position of the active, intervention group treated with a free-position active management, the rate of first exposed decline, the first,second and third of the total labor time and, finally adopted the mode of delivery, birth weight, Apgar score, 24h postpartum hemorrhage, maternal and neonatal complications of fetal activity were observed. Results The intervention group decreased fetal speed were significantly faster than the control group (P<0.05), the first and second stage of labor and total labor were significantly shorter than the control group (P<0.05). In the intervention group, vaginal delivery rate was significantly higher than the control group (P<0.05), vaginal delivery, cesarean section rate were significantly lower than the control group(P<0.05),birth weight, Apgar score between two groups,the difference were not statistically significance (P>0.05). In the intervention group, 24 h postpartum hemorrhage were significantly less than the control group (P<0.05), hemorrhage, urinary retention, neonatal asphyxia were significantly lower than the control group (P<0 . 05). Conclusion The implementation of active labor freedom fetal position can help decrease shorten the production process,improve the rate of vaginal delivery,reduce maternal and neonatal morbidity .
