Called Hypoxia of anoxia. If the fetus is in the womb for some reason can’t get oxygen in sufficient quantities, doctors to talk about fetal hypoxia.
The causes of intrauterine fetal hypoxia is diverse. These are common in pregnant women with asthma, chronic bronchitis, heart disease, diabetes, hypertension, and smokers. Hypoxia may occur due to severe toxemia, fetoplacental insufficiency, iron deficiency anemia, intrauterine infection of the fetus with herpes, toxoplasmosis, mycoplasmosis. Hypoxia and hemolytic disease of the fetus occurring as a result of rhesus-conflict. This happens in multiple pregnancies and polyhydramnios.
It is important to detect intrauterine hypoxia of the fetus. To do this, a pregnant woman should regularly visit the gynecologist and to pass all the examinations, which she appoints.
Distinguish between chronic and acute hypoxia of the fetus. In the second case, the fetus may die in a few minutes. This occurs when obvity umbilical cord, uterine rupture, placental abruption. In this case, one way out – an emergency C-section with subsequent nursing of a child in the neurosurgical Department.
Less dangerous chronic fetal hypoxia. She usually does not lead to the death of a child, but can disrupt the formation of the bodies, if there to 12 weeks of pregnancy, and at a later period of time causes damage to the nervous system, delay growth, and subsequently makes it difficult to adapt to extrauterine life. Subsequently, these children may experience neurological disorders, mental retardation.
About oxygen starvation may indicate not only a decrease but also increase of activity of the fetus, but it is a less reliable sign.
One of the first signs of fetal hypoxia – the reduction of physical activity. In normal pregnant woman should feel movement at least 10 times a day, if the child moves less, it may indicate a lack of oxygen.
The doctor may suspect the violation, listening to the heartbeat of the fetus: hypoxia its frequency is below normal and the heart sounds are muffled. To confirm the diagnosis can be assigned cardiotocography is a special procedure for the study of the fetal cardiac activity.
A sign of fetal hypoxia is a two-week developmental delay detected by ultrasound. In the presence of this disease pregnant woman hospitalitynet. If the cause of hypoxia is the disease of the mother, in the first place to treat it, of course, in ways which are not contraindicated during pregnancy.
The woman is prescribed medications that reduce the tone of the uterus, it can improve blood circulation in the placenta. Also used drugs that reduce blood clotting inside blood vessels, increasing the permeability of cells for oxygen, improves metabolism and the nervous system. In the future, the woman recommend special breathing exercises.
If chronic intrauterine fetal hypoxia persists despite the measures taken, it is necessary to resort to an emergency cesarean section. Of course, this is only possible for a period of more than 28 weeks.
