Contractions begin slowly, sometimes they precede false contractions, which may appear a few weeks before pregnancy and is called training. The woman in this period should be continuous monitoring of their condition, allowing it timely to go to hospital.
The real battle - a period of cervical dilatation
The true fight against false differ regularity and gradual decrease in the intervals between them. The first regular contractions occur at intervals of 20-15 minutes, then this time is reduced simultaneously with the increase in the duration, intensity and pain of contractions.
During contractions of the uterus muscles actively reduced, the muscle fibers contract, shifted relative to each other and stretched. In the different parts of the uterus work musculature occurs in different ways in the body of the uterus where predominant longitudinal muscle fibers, predominant reduction process, and in the lower part of the uterus - in the neck region and the isthmus where located mainly circular muscle fibers predominate during stretching and reduction.
The reduction is necessary in this case to ensure that after stretching the muscles are not returning to its original position. Thus, gradually, from the battle to fight the cervix opens. During the opening of the cervix is involved, as the reduction of muscles of the uterus, and the constant pressure from the top down membranes and the baby's head.
At first childbirth cervical dilatation is not as in repeated. In nulliparous women, first disclosed internal os of the cervix, then the cervix becomes thinner (anti-aliased) and finally opens the outer mouth. Women who give birth again, there is a simultaneous disclosure of the internal and external os - it significantly reduces the first stage of labor. Full disclosure of the cervix is considered an extension hole 11-12 cm.
How should behave the woman during labor
At home, when the fight has just begun, the woman during labor can walk or lie on your side - it prevents the compression of the inferior vena cava. When the contractions begin to appear every seven minutes, call an ambulance and go to the maternity hospital. By the time a woman to come, fights will occur more frequently, every five minutes.
In addition, the maternity hospital should go if the water broke, that is, violating the integrity of membranes. After violation of the integrity of membranes is a risk of infection of the fetus, therefore, delivery should take place quickly and under medical supervision.
Once the cervix is fully revealed, the integrity of the membranes under the influence of increased intrauterine pressure is broken and there is a timely rupture of membranes. Then the contractions become less intense or even stop for a while and then become very strong and moving in attempts - begins the second stage of labor - the period of the expulsion of the fetus.
Water can depart quickly or slowly - in this case, the discharge of their constrains the fetal head. The doctor has the opportunity to observe the process of discharge of water. The admixture of stool (meconium) of the fetus in the amniotic fluid indicates that the fetus suffers from a lack of oxygen. Even more dangerous, if the amniotic fluid have an admixture of blood - this suggests lacerations of the birth canal or placental abruption.
In order to speed up the delivery, women are advised to lie on the side where the detectable fetal neck. If the woman is lying on his back, it is best to take the semi-sitting position, since in this case the longitudinal axis of the fetus and uterus match, which will accelerate the delivery.
How bout affect the condition of the child
During contractions the uterus compresses the fruit, breaking both of his blood circulation. If the water has not moved, then the process is not as painful as the water is a shock absorber, a warning of fetal injury. After the discharge of water, and the shock absorber is no longer a child "get" even more. Therefore, during labor trying not to tighten too much, especially if you have already moved the water.
Throughout the period of the state of child labor are watching, listening to his heart, including using a special method of investigation - CTG. If the threat of fetal hypoxia increases, it raises the question of induction of labor or caesarean section.
Prepared woman, clearly showing that it will occur during childbirth, much easier to tolerate the longest, difficult and painful stage of labor - contractions. In addition, it is able to distinguish the true from the false contractions, that is to understand when starting labor.
