Delivery in a vertical birth chair supported by freedom of movement during labor: A randomized control trial

To evaluate the effect of delivery in a vertical birth chair (VBC) and traditional delivery table (DT) supported by women's movement during labor on the labor process, fetal outcome, maternal hormone levels, birth comfort, and satisfaction. This randomized controlled trial was conducted with 1:1:1 allocation. Group 1: in the VBC in upright position, Group 2: on the DT in supine position, these groups supported by freedom of movement, control group: on the DT in supine position, labor in bed. The duration of second stage of labor was not different between the groups (p = 0.246). The occurrence of instrumental birth, episiotomy, and perineal laceration was also not different among the groups (p = 0.772, p = 0.953, and p = 0.124). The use of uterotonic was observed in control group (p = 0.001). 1 and 5 APGAR scores of newborns were not different in all groups (p = 0.121, p = 0.268). The lowest pain score was observed in Group 1 (p = 0.001). Birth comfort and satisfaction were higher in Group 1 (p = 0.001 and p = 0.001). Decreased postpartum prolactin levels and increased postpartum oxytocin levels were observed in the control and Group 1 (p = 0.004, p = 0.006). Freedom of movement during labor and delivery using VBC in upright position can play birth-promoting and supporting role. There were no negative effects on the fetal outcome.
