Hypoxia cerebral edema
Hypoxia of the brain is a serious condition thatis due to the lack of oxygen that comes with the blood to the nerve cells. It should be noted that neurons are the most sensitive to oxygen structures in the body. In the absence of a normal amount of oxygen, nerve cells begin to die after only five minutes. This is why it is important to find this condition in time and provide the patient with the necessary help.
In fact, there are many factors that, one way or another, lead to oxygen starvation:
- Since hypoxia is associated with an insufficient amount of oxygen, it is first of all necessary to point out the cause of suffocation, drowning and pressure on the trachea.
- The same pattern is observed when inhaling a large amount of smoke.
- Hypoxia of the brain arises as a result of carbon monoxide poisoning, since this gas forms persistent compounds with hemoglobin of the blood - thus, red blood cells are no longer able to carry oxygen.
- Risk factors include some diseases that interfere with the work of the respiratory system, for example, paralysis of the respiratory muscles.
Hypoxia of the brain in newborns
Hypoxia can occur even at the stageintrauterine growth or during labor. Deficiency of oxygen in the fetus, as a rule, is caused by some diseases of the mother, including secondary toxicosis, high blood pressure, severe swelling, infectious diseases, placental insufficiency. Sometimes hypoxia develops as a result of wrapping the neck of the baby with the umbilical cord. Deficiency of oxygen leads to complications of development, and sometimes to termination of pregnancy.
Hypoxia of the brain and alcohol
Severe alcohol poisoning is also accompanied byoxygen starvation. After all, ethyl alcohol and its metabolites affect the properties of blood, affect the functioning of the cardiovascular system. For example, under the influence of ethanol, the transport properties of red blood cells are significantly weakened.
The main signs of oxygen deficiency can be different depending on the severity of the patient's condition:
- With mild hypoxia, inattention is observed,lost clear coordination of movements and the ability to foresight thinking. A person feels weak, dizzy, drowsy. The fact is that, first of all, the work of the cerebral cortex, whose zones are responsible for speech, fine motor skills, logical thinking, short-term memory, work only in those centers that provide physiological functions of the body.
- Severe hypoxia leads to loss of consciousness - this isdefensive reaction of the brain to oxygen deficiency. In the absence of medical care, the patient may fall into a coma. In the most severe cases, there is a stop of breathing, and then a heartbeat.
This condition requires immediate medical attention.assistance. Remember that with oxygen deficiency every minute counts. Treatment depends on the severity of brain damage. The patient is given all the necessary drugs in order to maintain the normal operation of the respiratory and circulatory systems, monitor the functioning of the whole organism.
