Causes of Retained Placenta
A retained placenta is a condition where the whole or a portion of the placenta and membranes are left behind in the uterus during the third stage of labor. It occurs when the placenta remains in the uterus for more than an hour after birth. A retained placenta occurs when all or part of the placenta remains inside the uterus after child birth. Normally the placenta is delivered within minutes to an hour after child birth. For some women, the placenta doe not deliver naturally and must be physically removed. If you have a retained placenta, it means that all or part of the placenta or membranes have stayed inside your womb (uterus) after the birth of your baby. Normally, your body expels the placenta and membranes after your baby is born, and they slide out easily through your vagina. Retained Placenta. A retained placenta occurs when all or part of the placenta remains inside the uterus after child birth. Normally the placenta is delivered within minutes to an hour after child birth. For some women, the placenta doe not deliver naturally and must be physically removed. There are three primary causes of retained placenta: 1  Weak or insufficient uterine contractions. 2  When uterine contractions are weak or inadequate the placenta is unable to detach from the uterine wall and be expelled. 3  The weak contractions may be secondary to hormonal changes which inhibit levels of oxytocin release. The placenta is said to be retained when it is not expelled from the uterus even 30 minutes after the delivery of the baby. Normally the placenta is expelled in three stage-it first separates from the uterine muscle, then it descends into the lower segment of the uterus and vagina and then it is expelled outside. In humans, retained placenta is generally defined as a placenta that has not undergone placental expulsion within 30 minutes of the baby’s birth where the third stage of labor has been managed actively. In humans [edit]. In humans, retained placenta is generally defined as a placenta that has not undergone placental expulsion within 30 minutes of the baby’s birth where the third stage of labor has been managed actively. Risks of retained placenta include hemorrhage and infection. Retained placenta (RP) is also known as retained foetal membrane or retained cleansing. RP occurs when the calf’s side of the placenta (the fetal membranes) fails to separate from the mother’s side. Causes of Retained Placenta: 1  Placenta separated but not expelled: The placenta may separate completely from the uterine muscle but may still be retained within the uterus. 2  There are three causes for this retention: 3  Failure of the woman to push out the placenta due to exhaustion or prolonged labour.
