Abstract
The third stage is the interval between delivery of the infant and delivery of the placenta. This stage averages 10 minutes and is considered prolonged if it lasts longer than 30 minutes, placental separation occurs as a result of continued uterine contractions and retractions, this control blood loss by compression of spiral arteries and also result in migration of the placenta into the lower uterine segment and then through the cervix.
The physiological effect of early cord clamping, a common intervention which is part of the active management of the third stage of labor, is to retain blood in the placenta, which prevents it from being so tightly compressed by the uterus. This is reduces the amount of myometrial retraction and contraction, leading to more bleeding. However, this blood is thought to form a retroplacental clot, which speeds up the shearing off of the placenta. Ultimately, the consequent delivery of placenta should lead to quicker hemostasis, but the intervention of cord clamping is a paradox in that it involves causing increased initial bleeding to lessen ultimate total bleeding.
Unclamping the cord at the maternal side and draining blood from the placenta would reduce its bulkiness, allowing the uterus to contract and retract and thus aiding delivery of the placenta.
Aim of this study is to evaluate the effect of placental cord drainage on the amount of blood loss during third and fourth stage of labour in vaginal delivery.
This is a prospective randomized clinical trial included Six hundred pregnant women admitted to the labor ward fulfilled the inclusion criteria and agreed to participate in this study which was divided into two groups control group (253) and study group (347) undergone normal vaginal delivery in which after clamping of the cord, the cord was left clamped in control group and unclamped in study group till signs of placental separation occurred and the placenta was delivered by Brandt-Andrews maneuver in this time blood loss was collected and measured. The results was that there a highly statistically significance as regard amount of blood loss and time of placental separation, and there was no statistical significance as regard demographic data, incidence of retained placenta and need of blood transfusion.
