THE LOW VALUE OF THE FUNCTIONAL TESTS ON THE STABILITY OF THE FETUS TO INTRAUTERINE HYPOXIA AS AN INDICATION FOR EARLY RESOLUTION OF BIRTHS BY CAESAREAN SECTION
It is shown that for the determination of reserves adaptation of the fetus to intrauterine hypoxia that may occur during physiological childbirth, and to select the resolution childbirth method, order birth «smart» child appropriate, since the 20th week of pregnancy, to periodically determine the stability of the fetus to intrauterine hypoxia through samples of Hausknecht. It is established that in the presence of a fetus reserves of adaptation to hypoxia, it retains «peace of mind», and his body is stationary, despite the fact that his mother is not breathing. Exhaustion of reserves of adaptation is manifested by the fact that the thorax of the fetus begins to make periodic respiratory motion. Therefore, the magnitude of the time interval between the beginning of the apnea in pregnant women and the moment of occurrence of the first respiratory movements of the ribs of her fetus indicates the amount of reserves adaptation of the fetus to intrauterine hypoxia. The longer the fetus stays stationary during the absence of the breath of the mother, the more reserves of adaptation to hypoxia. It is found that in the normal fetus has high resistance to intrauterine hypoxia and remains stationary for more than 20 seconds from the beginning of the breath of the mother. Therefore, when values of the test of Hausknecht more than 20 seconds to issue a statement in a high probability of the viability of the cells of the cortex of his brain throughout pregnancy and physiological l childbirth. Based on this, the decision about the advisability of keeping the pregnancy and birth of a fetus through physiological childbirth. On the other hand, it is shown that the pathology of pregnancy and the presence of fetoplacental deficiency reserves adaptation of the fetus to hypoxia and decrease when stop breathing mother sooner take his careless state: the body of the fetus loses stillness before the normal deadline. Thus, edges and the entire chest of the fetus begin to make breathing movements. It is shown that the value of the test Hausknecht less than 10 seconds indicates low resistance of the fetus to hypoxia and high probability of decline with increasing gestational age and/or duration of physiological childbirth. The fact that the gestation leads to an increase in body weight of the fetus, which inevitably increases the demand of its oxygen, and the approximation of physiological birth to her final stage leads to greater and more frequent contractions and undertakings, which inevitably causes intermittent ischemia of the placenta, therefore, when the low resistance of the fetus to hypoxia of the fetus often can not withstand the test of hypoxia and by the end of childbirth it appears acrocyanosis, asphyxia, defecation, drowning in the amniotic fluid and hypoxic damage to the cells of the cortex of the brain, which manifests itself by symptoms of ischemic encephalopathy in the newborn and mental retardation in children in the future. Therefore, when exposure during pregnancy values of Hausknechttest less than 10 seconds are given conclusion about the increased risk of hypoxic damage to the brain cortex cells of the fetus with increasing gestational age and duration of physiological childbirth. Based on this, to increase the likelihood of having children with high mental abilities in the future, the decision on the feasibility of accelerating the onset of childbirth and permits delivery by Caesarean section.
