truth? And I had to see how after the bite wasp a person begins to choke and
shine and then loses consciousness? And all
This is from a relatively innocuous insect bite. Bite is harmless, yes here
The reaction of the body is completely inadequate on it, as from the gun on the sparrows.
This is anaphylactic shock.
Causes of the development of anaphylactic shock
Any alien
Substance (for example, bacteria, viruses, medicines, poison insects and t.D.),
introduced into the body is called
antigen and in order to remove it,
The body produces antibodies that, bonding with an antigen, falls out in
precipitate and output from the body. This is
Normal organism reaction.
But sometimes the body's introduction to the introduction of an antigen gives a sharply increased reaction with a huge emission
the number of antibodies (sensitization), which settle on organs and tissues and
activate when re-introducing this antigen.
When connecting the antigen with an antibody, a number of biologically exempt
active substances (histamine, serotonin, bradykinin), which cause an increase
permeability of blood vessels, blood circulation violation in small
blood vessels, spasm muscles of internal organs and a number of other
violations. This contributes to the exit
Liquid blood in tissue and blood concentration. Blood accumulates on the periphery, internal organs and brain
obtain a sufficient amount of oxygen, which is the main reason
Losses of consciousness.
Symptoms of anaphylactic shock
Start anaphylactic shock sharp, sometimes lightning.
With a mild anaphylactic shock (duration
development - from a few minutes to 2 hours) the patient first experiences itching,
Then the feeling of gravity and
Sturses in the chest, difficulty breathing,
shortness of breath, redness of the skin, sneezing, runny nose, dizziness, head
pain, heartbeat, feeling heat, increasing weakness.
Average severity of anaphylactic shock: Redness of the skin is replaced by pallhery,
Suddenly, blood pressure drops, heartbeat, pain in the heart appear, sharp weakness. Possible
A variety of neurological manifestations: dizziness, violation,
anxiety, reduction of hearing, ringing and shm in the head and t.D. This background is possible
Development of an attack of bronchial asthma, disorders from the gastrointestinal tract (nausea, vomiting, diarrhea, abdominal pain) and kidneys (abundant
urination).
Severe anaphylactic shock is characterized by lightning
The development of collapse (sudden sharp weakness
Cardiac activity and falling blood pressure). The patient is sharply palenet,
The pulse is with difficulty, arterial pressure falls, the loss of consciousness comes, the pupils are expanded, their reaction
There is almost no. If the blood pressure continues to fall, then the heart stops and the breath stops.
Sometimes shock lasts literally minutes and ends with death.
After transferred anaphylactic shock there is a period
immunity, which lasts 2 - 3 weeks. At this time of manifestations of allergies
disappear (or significantly reduced). In the future, the degree of sensitization
The organism increases sharply, and the manifestations of the following cases of anaphylactic
Shock on this substance, even if it occurs after months and years, is characterized by a more severe flow.
After anaphylactic shock, complications may develop
The form of allergic damage to the heart muscle (myocarditis), liver (hepatitis),
kidneys (glomerulonephritis), various lesions of the nervous system, etc. May also
Shorten chronic diseases.
How to provide first aid for anaphylactic shock
Health care
A patient who is in a state of anaphylactic shock should be made
clearly, fast, in the correct sequence.
First of all, it is necessary to stop the further admission of allergen to the body:
Suspend the administration of medicinal
preparation, carefully remove the sting with a poison bag, if it was stung by the bee and
T.D. Above the injection site
(Suehenia) need to impose harness (if possible). Place of drug introduction
(svealing) is usually powered by a solution of adrenaline to create a local
Spasm of blood vessels, which prevents rapid distribution
Allergen.
Patient put in such a position that prevents
The spares of the language and the fall of the vomit in the respiratory tract, ensure the flow of fresh air, give inhale
Oxygen from oxygen pillow.
Further treatment
Anaphylactic shock is directed to neutralize biologically
active substances,
resulting as a result of the reaction
Antigen - antibody, normalization
Cardiovascular and respiratory activities, reduction
permeability of the vascular wall and preventing late complications with
Parties internal
organs.
Predict the appearance of anaphylactic shock in most
Cases are impossible. But you need to pay attention to the manifestations of allergies to
other substance (drug, food product and t.D.) and in the future
try to avoid re-introducing this substance in the body.
