The data of the literature testify to the undoubted dependence between the state of the newborn and the parameters of the acid-base state of its blood, therefore, when determining the fetal condition during childbirth, the results of the analysis of blood taken from the skin of its head are crucial, and the acidosis can be recognized at any stage of childbirth .
In the process of normal delivery in the fetal physiological state a gradual increase in the frequency of meconium in the amniotic fluid occurs, but there are no significant differences between the groups.
There are four moments of the mechanism of birth. The first moment is the bending of the head; the second is the internal rotation of the head; the third is the extension of the head (the region of the suboccipital fossa is the fixation point - hypomochlion); the fourth is the inner turn of the trunk and the outer turn of the head.
In modern obstetrics, an important place is given to artificial rhizopoiesis. It is believed that the proportion of provoked births should not exceed 10%.
In recent years, interest in programmed birth has increased again. In a number of cases, the artificial delivery is performed on time without medical indications, when the fetus has reached full maturity, and there are no signs of spontaneous delivery. Such preventive labor excitement in normal pregnancy is called programmed delivery.
Anomalies of labor activity - an urgent problem of modern scientific and practical obstetrics. The importance of this issue is due primarily to the fact that this pathology is one of the main causes of serious complications in both the mother and the child.
Recognition of the initial symptoms of violations of motor function of the uterus in childbirth, a comparative evaluation of the effectiveness of treatment of anomalies of labor activity based on clinical observations alone is very difficult, so now the methods of monitoring monitoring in pregnancy, even at home, internal hysterography, cardiotocography.
The prognosis of labor and the strength of uterine contractions is almost impossible. Some authors begin to use in the birth of uterotrophic drugs (oxytocin, prostaglandin), when the uterine activity according to the internal hysterography when it is registered for an hour does not exceed 100 units. Montevideo.
To clarify the nature of the breach of contractile activity of the uterus in the early stages of its development, along with the study of coordination, strength and frequency, duration and rhythm of uterine contractions, it is also necessary to take into account the disturbances of the tone of the uterus.
The central problem in modern obstetrics is the regulation of labor, since clarifying the nature of the mechanisms that stimulate the contractile activity of the uterus is a necessary prerequisite for reducing the number of pathological births, surgical interventions, hypo- and atonic bleeding, and reducing perinatal mortality.
