The aim of this prospective randomized clinical study is to compare whether the removal methods of placenta during cesarean section have an impact on perioperative hemorrhage.
One hundred women with singleton term pregnancies undergoing elective cesarean section through lower segment transverse incision under general anesthesia were included in this study. They were randomly allocated to two groups according to the type of removal of the placenta from the uterus after childbirth; manually or spontaneously. The main outcome measures were change in hemoglobin levels after cesarean section. The secondary outcomes were operative time, required transfusions and postcesarean endometritis.
Fifty patients were randomized to the manual removal group and 50 to the spontaneous group. The demographic characteristics of the two groups were similar. There were no difference in terms of change in hemoglobin levels after cesarean section between two groups (1.6 ± 1.0 and 1.5 ± 1.0, respectively; P = 0.711). In addition, none of the patients required blood transfusion and showed postpartum infections.
There is not an association between the method of removal of the placenta and postpartum blood loss in cesarean section deliveries.
