Pregnancy - a difficult period, during which both the woman and the fetus could pose many dangers. One of these dangers - the insufficient supply of oxygen to the tissues of the fetus. In this condition more often affects the brain, resulting in the child's body may occur various violations.
What is hypoxia and why it develops in the fetus
Hypoxia (oxygen deficiency, anoxia) - a condition that develops when the body's insufficient oxygen supply to tissues, or in violation of its assimilation.
Hypoxia can occur against the backdrop of a violation of the structure of the placenta and its blood circulation in late toxicosis of pregnancy, exposure to drugs and other harmful factors. This leads to chronic fetal hypoxia associated with decreased oxygen in the blood, which causes dysfunction of the central nervous and cardiovascular systems, the regulation of homeostasis (constancy of the environment within the body), increased permeability of blood vessels and so on.
Fetal Hypoxia is a major cause of damage to the central nervous system of the fetus and newborn with various violations of the physical and psychological development of the child, with the degree of abnormality depends on the duration and severity of fetal hypoxia.
In order to avoid disastrous effects of hypoxia on the fetus, the pregnant woman should regularly be seen in the antenatal clinic. In the process of examination and additional methods of diagnosing fetal hypoxia will be promptly identified and treated.
There are acute and chronic fetal hypoxia. Acute fetal hypoxia occurs more often in childbirth. Chronic fetal hypoxia, which lasts more than a week, usually occurs on the background of a long proceeding diseases of the pregnant woman.
The very pregnant woman can not feel any discomfort during fetal hypoxia. However, during an inspection of an obstetrician-gynecologist may suspect hypoxia, listening to the heartbeat of the fetus.
In order to confirm fetal hypoxia it is currently the most widely used method of CTG - monitor observation of the fetal heart rate. This estimated heart rate (heart rate, the rate - 120-160 u. / Min), the fruit, rapid changes in heart rate from beat to beat (oscillations, normally their amplitude should not exceed 3-6 cycles per minute), and slow changes in heart rate ( aktseleratsii - normally can be isolated and decelerations - there should be no). At the present time to increase the accuracy of diagnosis of fetal hypoxia used computer decryption kardiotokogramm.
To determine the fetal movement applies aktografiya - registration of movements via ultrasound.
In order to improve the diagnostic accuracy and precision of the forecast data for the fruit of all the studies evaluated in the complex, resulting in a calculated fetal biophysical profile (BFN). The normal state of the fruit is graded 8-10. Rank 7 points require re-examination. In assessing the points 4-6 start treatment of fetal hypoxia. In assessing the prognosis of less than 3 points to the fetus is unfavorable.
It is currently being developed and implemented in the practice of antenatal study of the volume and speed of blood flow to the blood vessels of the uterus, umbilical cord and fetal ultrasound Doppler method.
The presence of fetal hypoxia and some say blood biochemistry.
The main signs of fetal hypoxia: violation of the heart rate (heart rate initially accelerates and then slows down), first fetal heart tones are more sonorous, and then more and more deaf, impaired heart rate. Further, we can note a decrease motility of the fetus.
Treatment of fetal hypoxia
Treatment of chronic fetal hypoxia should begin with the treatment of diseases caused such a condition (acute and chronic diseases, pregnancy complications). Pregnant woman have to abandon the use of any negative effects on the fetus substances (smoking, alcohol, drugs, self-administration of any drugs, and so on).
Of great importance are a balanced diet with adequate protein, fats, carbohydrates and vitamins, protective mode (and sometimes bed), healthy sleep
Dreams: how to understand our dreams
, walks in the open air.
To remove the oxygen deficiency use inhalation of oxygen, drugs that improve the flow of blood, including the blood flow in the mother-placenta-fetus. To improve the metabolism prescribe drugs that do not have a toxic effect on the fetus, such as aktovegil.
The best prevention of fetal hypoxia - the right way of life and regular monitoring in the antenatal clinic of the pregnant woman.
