Placenta Does Not Come Out
While most people think of labor and childbirth solely as the process of a child being born, most do not know or realize that the process is not complete when the child is born. Rather, the final stage of labor actually involves the placenta being expelled from the uterus after the birth has occurred. In most cases, this occurs automatically minutes after the baby has passed through the birth canal.
Retained placenta is an uncommon delivery complication that occurs when the placenta does not come out on its own but rather remains inside the womb after the baby comes out. If this occurs, doctors must intervene to manually manipulate the placenta out of the womb. Otherwise, if the placenta is left in the womb, a very serious and potentially fatal infection can develop.What Should I Know About a Retained Placenta?
When the placenta has not been expelled within 30 minutes after delivery it is diagnosed as retained placenta because the body has kept the placenta rather than expelling it in the normal timeframe. If retained placenta goes untreated (i.e., the placenta is not removed), a woman becomes very susceptible to postpartum infection and potentially dangerous blood loss, both of which can very quickly become life-threatening.
There are actually several different types of retained placentas and they differ considerably in how they occur and the risks associated with them. Specifically, there are three classifications of placentas that are described below.
- Placenta Adherens occur most frequently among the three and are a result of contractions not strong enough to expel the placenta in its entirety. As a result, the placenta remains loosely attached to the uterine wall.
- Trapped Placentas occur when the placenta is left inside of the uterus. The placenta will fully detach from the wall of the uterus but fails to be expelled. In most cases, this happens due to the cervix closing prior to the placenta being expelled.
- Placenta Accretas: sometimes retained placenta is caused by another complication known as placenta accreta which occurs when the placenta attaches itself too deeply into the wall of the uterus. This causes a much more difficult delivery and in many cases causes severe bleeding. The placenta usually must be either surgically detached or an emergency hysterectomy must be done to remove the uterus entirely.
While any woman can experience a retained placenta, there are some factors that can increase the likelihood of experiencing one. For one, retained placentas are more common in women who become pregnant after they turn 30.
Additionally, premature deliveries occurring prior to the 34th gestational week can increase the risk as the placenta needs to remain in place until gestational weeks 34-40. Having a very long first and second stage of delivery can also increase the risk and be a sign you may experience one. Lastly, retained placentas are common in women who deliver a stillborn baby.Managent / Treatment of Retained Placenta?
Removal of the placenta from the womb is the only treatment option for a retained placenta, however, there are different methods of manual removal. You can opt for an anesthetic and the OB/GYN can try to remove it manually, but the risk of infection is elevated.
There are also medications that can be used to either trigger additional contractions or relax the uterus muscles and help expel the placenta.
Breastfeeding causes the uterus to naturally contract which can sometimes be enough to expel it. Also, a full bladder can impede the placenta from expelling out of the womb. As a result, in some cases urinating actually can help effectively expel the placenta. When none of the above methods work to expel the placenta, in some cases emergency surgery is needed, although it is only used as a last resort as it carries a number of complications.Complications of a Retained Placenta?
When it comes to a retained placenta, there are a number of complications that may arise and that you should be aware of. For one, retained placentas can result in a primary postpartum hemorrhage resulting in excessive heavy internal bleeding.
While anesthetics can help during the delivery process, they can result in further risks particularly if you are planning to breastfeed immediately after the procedure. This is because your system will have traces of the drug within it which will pass those traces to your breastmilk.
You also want to ensure that when coming off an anesthetic you are alert enough to hold and support your baby. If you decide to opt for an anesthetic, however, the OB/GYN will manually remove the placenta and remaining membranes manually. Following the procedure, you will be prescribed antibiotics to mitigate the risk of infection while other drugs will be prescribed to help the womb contract.
