Expulsión de la placenta, la última etapa del parto

After the birth of the baby the uterus rests for about fifteen minutes and after that will continue to produce contractions until expulsion of the placenta. This is the third stage of labor, and unlike the others, is painless.

Here the placenta detach from the uterine wall, and out the birth canal and the large blood vessels that communicate with the uterus are torn, but despite this a few times, give rise to hemorrhage as the fibres of the uterus are intertwined, so that when it contracts the uterus muscles tighten the blood vessels and prevent bleeding.

For this reason it is very necessary for the uterus to contract to form a ball harder after the expulsion of the placenta. The performing of massage newspapers during the following sixty minutes at the end of the third stage will help keep the uterus contracted. This stage lasts between ten and twenty minutes.

Expulsion of the placenta

Usually the matron or specialist in charge of labor does not attempt to remove the placenta until there are clear signs of its detachment from the uterine wall and its descent into the vagina. The signals that will be outstanding assistants of labor are contractions that become to start minutes after the birth of the baby and demonstrate that the proximity of the detachment of the placenta, and with it will come their need to push again. This also indicates that the placenta has separated from the uterine wall and tap the base of the pelvis.

When you appear these signals should help expel the placenta by gently pulling on the umbilical cord at the same time that you press above the edge of the pelvis to control the descent. The placenta is expelled through the birth canal, followed by the membranes and in few occasions they are still clots of blood.

When it completes the expulsion of the placenta, the medical team will examine you carefully to ensure that you are whole and that there are no remains in the uterus. If it is placenta in the uterus can cause bleeding later so, it is important for their rapid removal. In case of doubt an ultrasound is done to check that the uterus is completely empty. The membranes should form a perfect bag, with the exception of the hole where he spent the baby.

In addition should examine the end severed with the umbilical cord to make sure that the blood vessels are normal. After the expulsion of the placenta be examined with attention to the area of the vulva for tears that must be sutured immediately.

In 1935 he initiated the use of ergometrine and doctors, midwives, specialists or medical team in charge can have control during the third stage of labour, or expulsion of the placenta. Thanks to the ergometrine reduces bleeding.

The post partum hemorrhage

It is not common, because the uterus has its own device to protect you from loss of blood. Once the uterus is completely empty, it contracts until reduced to the size of a tennis ball. The contraction of the uterine muscles squeeze the arteries local that no longer can bleed. It is normal to bleed little after the birth, and the little blood that appears does so in the form of loquio, normal vaginal discharge after childbirth.

The loquio is red during the first two or three days, then turns brown and disappears after a couple of weeks. If there is placenta within the uterus there will be post-partum hemorrhage. Why examine the placenta after its expulsion, to be able to extract the parts that have been left in the uterus. After you give the woman general or regional anesthesia, removed gently the remains of the placenta by pulling it out from the inside.

If there is bleeding twenty-four hours after delivery, appears the loquio bright red. That happens if you move a lot, your doctor will probably recommend plenty of rest the days following.
