This condition, which can be followed by syncope, develops due to a sudden change in blood pressure.
In turn, the pressure change may occur due to the lack of oxygen content in the air, due to the high temperature of the air, due to the increased humidity of the air, and also due to physical and mental fatigue, due to insufficient nutrition the result of any disease, etc.
The greatest likelihood of pre-unconsciousness and fainting in the last trimester of pregnancy. The explanation for this is simple: the uterus, which has reached a considerable size by the end of pregnancy, weighs heavily on the large arterial vessels passing behind it, pinches them a little, and therefore there is a slight decrease in blood pressure, which leads to a pre-syncope (skin pallor, general weakness, feeling of nausea, tinnitus, blackening of the eyes, dry mouth, etc.). The risk of pre-unconsciousness is even greater if the woman turns back on her back: the heavy uterus at this time puts a lot of pressure on the blood vessels that we talked about.
In order to avoid fainting, a woman is recommended:
- if possible, exclude moments that could trigger the development of a fainting state: regularly ventilate the premises, ensure that the rooms have hygienically acceptable temperature and humidity; to pay attention to the fact that the residential premises do not have any strong irritating odors;
- avoid psycho-emotional stress; avoid intellectual and physical stress;
- ensure yourself an opportunity for adequate rest; organize comfortable conditions for recreation;
- if a woman has been engaged in any activity and has felt the approach of fainting, she should stop that activity and rest in a prone position (on the right side); when approaching fainting, the body must be given such a position that the head is slightly below the body; when a person is in this position, the blood in his body is quickly redistributed — it flows to the center — and his well-being quickly improves;
- traditional medicine recommends that when approaching syncope, actively inhale with the nose of a pair of freshly ground onion; due to irritation of the mucous membranes of the nose and nasopharynx by these couples, the blood and lymphatic vessels of the mucous membrane dramatically expand, and blood and lymph flow to them; due to this redistribution of body fluids, the general condition is rapidly improving;
- at the onset of the first signs of a pre-unconscious condition — that is, when a general weakness occurs, nausea, etc. — you need to rub as quickly as possible the temples and the forehead area of one or another alcohol-containing liquid; vodka, any cologne can be used; use the ammonia solution (ammonium hydroxide), which is traditional for such cases; can also be used for grinding the temples and forehead vinegar (not the essence!); it is recommended to grind the limbs with the use of the above mentioned agents;
- when the first signs of pre-unconsciousness appear, a mustard plaster should be placed on the occipital region; there is a distracting effect – blood and lymph flow to the head, and the general condition is normalized;
- organize regular meals; adhere to the principles of good nutrition (if necessary, discuss nutrition with your doctor or dietician). In case of fainting, it is recommended:
- the patient must lie down, and the legs should be placed at a slightly higher level than the head;
- undo the top buttons of clothes; free from tight clothing neck and chest;
- moisten your face with cold water; grind whiskey;
- as quickly as possible to bring to the face a cotton wool moistened with ammonia;
- urgently provide access to fresh air – wide open the window;
- immediately after the woman regains consciousness, give her to drink hot long-leaf black tea;
- if it is known that the cause of fainting is in malnutrition (and therefore, in lowering blood sugar levels), the woman is required to eat something sweet; in this case, good are sweet fruits and sweet fruit juices, which contain large amounts of easily digestible sugars.
