Abstract: Objective To analyze the effect of liberal position combined with the use of delivery equipment on the improvement of labour outcome. Methods Totally 110 primiparas who delivered with liberal position combined with delivery equipment including delivery ball, yoga pad, labour chair, and wall handrail in Tai' an City Central Hospital were recruited randomly as liberal position group, while 115 primiparas who delivered with traditional position in the same period were recruited randomly as the control group.The differences of labour time, natural childbirth rate, the amount of postpartum hemorrhage, neonatal Apgar score, visual analogue score(VAS), self-rating anxiety scale(SAS) score, and patients' satisfaction between the two groups were compared. Results Compared with control group, cesarean section converted rate in the liberal position group was lower(1. 67%vs.9. 57%), natural child birthrate was higher(98. 33%vs.87. 83%), the total labor time was shorter(9. 10 ± 0. 30) hvs.(13. 30 ± 0. 36) h, the amount of postpartum hemorrhage was less (220 ± 38) mL vs.(300 ± 35) mL, VAS was lower(5. 02 ± 2. 26)vs.(7. 78 ±1. 64),SAS score was lower(31. 54 ± 3. 30)vs.(47. 12 ± 4. 50), and postpartum satisfaction rate was higher(70. 9%vs.24. 3%), and the difference was statistically significant(all P< 0. 05). Neonatal Apgar scores were not significantly different between the two groups(P> 0. 05). Conclusion Liberal position delivery combined with delivery equipment can effectively increase natural childbirth rate, reduce the amount of postpartum hemorrhage, shorten labour time, reduce pain and psychological anxiety, and improve postpartum satisfaction.
