The childbearing

Beginning

Date of childbearing

Every pregnant woman likes to know what accounts his gynecologist does to programme with so many accuracy his date of childbearing. In fact, his calculations are based on the calendar of fertility of a woman from his ovulation.

What the doctor does is to take the date of the last menstruation (the first day) and to add forty weeks (280 days) or, what is the same, ten lunar months. Since a normal pregnancy lasts between 38 and 41 weeks, the date of childbearing can be fixed by enough precision. In these weeks, it is considered to be a pregnancy to “term“, this one concept aims to the risk perinatal, that is to say, at the danger with which the baby should fall ill, or should die inside the womb, or fura of him.

The birth of the baby is not submitted to rigid laws, for what can go forward, or be late due to multiple factors. Also, not all the women have such a regular period. Anyhow, this is the date that the doctor cites as an example to calculate the date of childbearing.

Another way of calculating the probable date of childbearing, is to add up 10 days to the date of the last menstruation, and to reduce him 3 months. This calculation, as well as previously mentioned, they have a margin of error of one week earlier, and one week after the estimated date of childbearing. In general, serious risks do not exist up to the week 42 of gestation (294 days). This is the margin that the doctors usually take as a limit to induce or not to the childbearing or Cesarean section, according to the state of the baby and of the mom.

Induction of the childbearing

The induction of the childbearing is a complex procedure that can bring complications in itself, according to the handling of the dripping in the whey of the woman in childbirth. He is for it the doctors they usually doubt enough before applying the induction. There is always better a childbearing the most natural thing that one could, although to induce it can save lives. The maternal suffering of a work of childbearing prolonged is always better that the fetal suffering for strong contractions before a dripping administrated evil. But these cases are rare. There are no reasons to be afraid of the induction – unless they have mentioned to you that it can be painful, but this is according to the doses and the circumstances.

There are still not known the causes that do that the childbearing does not take place spontaneously. When he takes a long time, a widespread anxiety exists, not only the mom becomes nervous, if not that all those who surround the pregnant mom worry, and he is generated to the mom by more nerves than containment.

The induction, the obstetra will decide it to prepare disorders motivated by the shortcoming of nutrients and of oxygen that receives the fetus across the afterbirth.
Other one of the complications that appear when the probable date of childbearing passes, it is that the baby keeps on growing inside the womb. On having been born, his weight will be higher than the normal weight of a baby born to term (more than 4 kilos), and the biggest disparity between the size of his head and the size of the pelvis of the mom, the possibility of Cesarean section will increase greatly.

One of the principal factors that define the induction, is the fetal health. If the baby is in the good state, the induction of the childbearing can be tried, administering oxitocina or prostaglandin, both substances provoke uterine contractions. It is clear that before the induction it must be checked that the neck of the womb is soft and extensive, since if it is immature and without dilation, the induction perhaps fails, and a Cesarean section should be realized. Also, there must be evaluated the size of the baby and his relation with regard to the size of the pelvis of his mother.

On the other hand, when the baby is awkward, it will be necessary to evaluate his possibilities of confronting a work of childbearing, which will be always controlled by fetal monitorings during all the work of childbearing, (from the last weeks of the pregnancy,

The presence of the neonatólogo is very important in a delayed childbearing, since the risk that the baby is born with certain grade of respiratory depression or with some complication inherent in the liquid meconial, is major. For the long time, to the babies that meconial were born with amniotic liquid, there was sucked the mouth, the nose and the pharynx before they were breathing for the first time, to prevent the liquid from moving to the lungs. Today, most of the doctors neonatólogos and obstetras it coincides that this maneuver, it is unnecessary, and even harmful.

At present, when the baby is born, during the first hours, a nurse or the doctor neonatólogo will be attentive to detect complications in the regulation of the glucose and the calcium, since in these babies hypoglycemia episodes usually take place and hipocalcemia.

Advantages of the ultrasound scan

What are the most reliable methods to calculate the probable date of childbearing? There is not doubt that many pregnancies show off to be longer than the habitual thing, why in fact the date of childbearing was calculated badly. Sometimes, why does not the mom remember the date of his last menstruation, or why was it very irregular in his menstrual periods.

For this motive, the measurement is very good of carrying an early ultrasound scan out, to the beginning of the pregnancy. The ultrasound scan is a very reliable study, and during the first trimester, it allows to establish the age gestacional with a margin of error lower than one week.
