Placental drainage versus no placental drainage after vaginal delivery in the management of third stage of labour: a randomized study

Objective: To asses the effectiveness of placental blood drainage after spontaneous vaginal delivery in reducing the duration, the pain and blood loss during third stage of labour against no placental drainage. Methods: In this randomized controlled study, 222 pregnant women who admitted to Zeynep Kamil Women and Children’s Health Training and Research Hospital from December 2016 and July 2017 were included. They were randomized into study(111) or control(111) group when they delivered vaginally. In study group; umbilical cord was clamped from fetal side but unclamped from maternal side. After that unclamped side of umblical cord was left open to drain the blood until the flow stopped. In control group the umblical cord was clamped both sides. Results: The duration of third stage of labour was 18,39±6,85 min in the study group and 22,78±5,90 min in the control group(p<0,0001). The mean blood loss in study group was 212,75±12,1 and was 308,42±18,4 ml in the control group(p<0,0001). The mean respective visual analog scale (VAS) scores in study group and control group were 5,65 and 6,58 (p<0,0001). Conclusions: Placental blood drainage was effective in reducing the duration of the third stage of labour, the blood loss in the third stage of labour, and also the pain in the third stage of labour
