As is known, the entire period of the generic process consists of 3 stages, the most prolonged of which is the opening of the uterine neck . It begins with the appearance of the first fights and continues right up to the full disclosure of the uterine neck. In primiparous women it lasts about 8-10 hours, and those who give birth repeatedly - 6-7. Let's take a closer look at this stage and talk about how the perversions begin to struggle and what sensations they experience.
Latent phase of the first stage of labor
It begins with the establishment of regular, rhythmic fights, the frequency of which does not exceed 1-2 in 8-10 minutes. At the same time, the first contractions in primiparas begin, as light, tingling pains in the lower half of the abdomen, which can give to the lumbar region.
The latent phase lasts for an average of 6 hours. It ends with a shortening of the neck, at which the opening of the uterus of the uterus occurs.
How is the active phase?
With the opening of the uterine neck at 4 cm, the active phase of the first stage of labor begins. As a rule, it is characterized by active labor activity. It is at this time that most women begin to experience very painful contractions, which in primiparas may require the introduction of drugs to relieve muscle spasm and stimulate labor .
At the beginning of this phase, contractions in primiparas are observed with a small frequency - 5 times in 10 minutes. In this case, pain is observed mainly in the lower abdomen. With the great activity of the woman herself (walking, standing), the intensity of contractions increases dramatically. Often at this stage, the puerpera have to inject with anesthetic and antispasmodics.
The autopsy of the fetal bladder occurs at the height of the fist, with the opening of the cervix is 7-8 cm. At the same time, the baby's head begins to advance along the birth canal. At the end of this period, full opening of the pharynx is observed, and the head is lowered to the level of the pelvic floor.
The deceleration phase is the final period of the uterine cervix opening
At this time, the neck opens up to 10 cm, which makes it possible for the fetus to appear. The woman herself may get the impression that the birth process has stopped. This lasts for 20 - 80 minutes. As a rule, this phase is absent in the reproducers.
How to understand the primipara, that they started contractions?
Quite often, even before the birth itself, in about 3-4 weeks, many women begin to experience a phenomenon such as training bouts. If the future mothers who are pregnant with the second and subsequent toddlers practically do not attach any importance to this, then the primiparous often take them for generic. To distinguish them from those that are observed before childbirth, it is necessary to know that the training ones do not grow and have no periodicity, i.e. can occur at any time.
According to the sensations of the struggle in the primipara, they practically do not differ from those who experience
Thus, it can be said that the onset of labor in primiparous women is similar in sensations to the pain that they experience before menstruation, but they are more intense and expressed. In view of the fact that the period of disclosure of the uterine neck in primiparas is longer, it is not necessary to go to the hospital with the first appearance of fights. It is better to wait for the period when their periodicity will reach 8-10 minutes. In this case, obstetricians will have enough time to prepare a woman for childbirth.
