Being pregnant is one of the most beautiful stages of every woman and it is that noticing how a life grows within us is something unique that only women are capable of understanding . However, for any pregnant woman there is one thing they fear but look forward to, which is the delivery of our baby. This is why it is normal to want to find out how this will develop, because of this from PregDream we are going to explain what the most common birth that occurs in pregnant women consists of, which is physiological or natural childbirth.
WHAT IS A PHYSIOLOGICAL DELIVERY
A physiological or natural delivery is a delivery that begins spontaneously from the beginning to the end when the baby has already arrived in the world. In this delivery the baby comes out vaginally with the head down being the first thing to come out. It occurs around weeks 37 to 42 of gestation and this delivery occurs when the entire pregnancy and delivery has flowed in the ideal conditions and there is no danger for the mother or the baby.
In these cases, the World Health Organization recommends that the least intervention be made to guarantee the safety of the mother and the baby, since otherwise they could suffer collateral problems. It must be remembered that a vaginal birth is not always a natural or physiological birth since if some instruments are used to get the baby out , we would no longer be talking about a natural birth.
PHASES OF A PHYSIOLOGICAL LABOR
Prodrome or antepartum period
Before the moment of labor arrives, it is frequent that the pregnant woman begins to notice some slight and irregular contractions that disappear or lessen when changing position, these contractions are called Braxton Hicks contractions and they are not labor contractions, but they serve to prepare the body for when the time comes.
This is one of the main reasons why a woman thinks she is in labor , however, this is not the case since your body with these contractions does not begin to dilate . This phase can last for hours and even days, but the great moment is very near.
Start of labor
The symptoms that a pregnant woman has at the time she goes into labor are the following:
- Her cervix is at least fifty percent effaced.
- The pregnant woman will be dilated by at least three or four centimeters.
- And you experience regular, intense, and frequent contractions (about two or three every ten minutes).
Only when these conditions have arisen is when we can begin to prepare the backpack for the hospital because we will be in labor, it is best to dress and prepare as soon as possible to go to the hospital . If this is not the case, they would admit us early and this would be very bad for us since the doctors will understand that labor is not following its natural course when what has really happened is that we are not in labor.
Something to keep in mind is that the amniotic sac does not have to be ruptured for labor to begin, in fact, if the sac ruptures, but does not have contractions, this means that we are not yet in labor. In the same way, if you notice all these symptoms and throughout your admission you see that your bag continues without breaking, you should not worry, since the bag will break during labor in some contraction or even in the expulsion of the baby. In very rare cases the baby comes out with the bag intact.
Dilation is the process by which the cervix increases in diameter so that the baby can exit through the vagina. This dilation is measured in centimeters and the process of giving birth will begin when the cervix reaches 10 centimeters .
Contractions are considered adequate when, with increased dilation, the pain that the pregnant woman is suffering is bearable so that neither the mother nor the baby is endangered . If, on the contrary, the contractions are very painful and the pregnant woman is not dilating, this may indicate that something is not right. Regarding the rhythm of the contractions, their duration and time, nothing can be said since each woman dilates in a different way, there are some that can do it very quickly while others can take hours.
When the pregnant woman already reaches seven or eight centimeters of dilation is when the moment has come and the expulsion phase will begin where the future mother will have to start pushing when noticing the contractions so that her child can finally reach the world. When starting to push, the baby’s head will descend through the mother’s pelvis , rotating and accommodating, until the moment when it reaches the floor of the perineum, which is the lowest area of the pelvis. At this time, the baby’s head begins to appear through the vagina, one of the hardest moments of childbirth: expelling the head.
This phase is called crowning , and it is at this time that the baby’s hair begins to be seen through the orifice of the vulva, (it is possible that with each contraction this retracts and then reappears). All these movements make the perineum become more and more flexible to adapt to the size of the baby’s head and that it can finally come out. In the first delivery this usually takes longer while in the following this flexibility is achieved more quickly.
Just when the head is in the perineum is the moment where the pregnant woman can feel a very intense burning sensation , this is called a ring of fire since the skin of the perineum is stretching as much as possible so that the baby can come out without no injury is caused. There are some deliveries where as soon as the head comes out the baby comes out without any further push, however, this is not very frequent and it is normal that the shoulders also need to come out so that it can come out without problem.
Delivery of the placenta
Although the baby has come into the world, that does not mean that the delivery is over and it is that the placenta needs to come out . Far from what everyone thinks, the placenta does not come out as soon as the baby is delivered , but usually comes out after the umbilical cord stops beating, usually ten to thirty minutes later. If after that time the placenta has not come out, there is no need to worry since sometimes it can come out up to an hour later and in each woman it is different.
