Background : Worldwide, caesarean section is the most common major operation performed on women. The method of removing the placenta is one such procedure that may contribute to an increase or decrease in the morbidity of caesarean section. Delivery of the placenta by cord traction at caesarean section has more advantages than manual removal. To the best of our knowledge no information has addressed the optimum time interval between the delivery of the infant and of the placenta with minimum side-effects.Objectives : The main objective of our study is to estimate the best time needed to start the delivery of the placenta after fetal delivery in caesarian section that allow placental delivery without undue morbidity.Patients and Methods : One hundred and twenty patients admitted for elective or emergency cesarean section after 34 weeks of gestation were recruited in a randomized, controlled clinical trial between October 2009 and May 2010 at the Gynecologic and Obstetric Department of Cairo University Hospital, Cairo, Egypt. Following study enrollment, 120 patients were randomly assigned to one of the four study groups as follows: group A, group B, group C and group D (According to the time of beginning cord traction on the placenta after fetal delivery; after 15, 30, 45, 60 seconds respectively). The time taken for the placenta to separate (seconds) was the primary outcome; while the secondary outcome was the amount of blood loss (in ml) from placental bed due to its separation.Results : In this study, group (D) patients gives the best results in the amount of blood loss from placental bed (125.36 ± 7.96, n=30), as well as the least time interval from starting cord traction till complete delivery of the placenta(24.7 ± 4.41, n=30). Group (A) shares that it has also little amount in blood loss from placental bed (123.8 ± 16.87, n=30), but with more time interval from starting cord traction till complete delivery of the placenta (27.4 ± 5.02, n=30).With respect to complications during delivery of the placenta as cord avulsion, incomplete removal or manual removal; those happen more frequently in group (A) (25%) than group (D) patients (16%), (n = 30). The remaining groups, (B) and (C), give the worst results in the amount of blood loss from placental bed as well as the longest time interval from starting cord traction till complete delivery of the placenta.Conclusion : Our study suggests that waiting enough time (at least 1 minute) after delivery of the fetus to start cord traction helps in reducing the amount of blood loss from placental bed as well as reducing the time interval needed for placental separation after starting cord traction with least morbidity.
