Chemical burn: first aid and home treatment

Chemical burnAny chemical burn, both actually and thermal, is characterized by damage to the human body in contact with chemicals that can cause tissue destruction.

This is in most cases acid, alkali, volatile oils, bitumen, kerosene and gasoline, phosphorus, etc. Moreover, most often affected areas belong to the upper limbs, less often to the lower extremities, even less often to the trunk. But sometimes the eyes, the face or organs of the esophagus and the mouth are affected by such a burn.

It should be borne in mind that the consequences of such a burn depend on the depth, severity of the penetration and concentration of the chemical, and on the quality of timely treatment. In this article we will look at the types of chemical burns, their photos, and also find out what first aid should be given to a person at home under a chemical skin burn.

Degrees of chemical burns

With such burns, skin of the face, hands, esophagus and stomach are most often affected. The main substances that cause burns are acids (sulfuric, hydrochloric, nitric, hydrofluoric, etc.), alkali (caustic soda, caustic potash and others), gasoline, kerosene, salts of heavy metals (zinc chloride, nitric silver, etc.), some volatile oils, phosphorus, bitumen.

The severity of the damage to the skin and mucous membranes during a chemical burn depends on the concentration of the substance and the duration of its action on the tissue. It is generally accepted to allocate 4 degrees of severity of a burn with chemical substances:

  • 4 degree. The lesion affects all tissues, including the skin, muscles and tendons.
  • 3 degree. Lesions are exposed to those layers of skin that are located near the fatty subcutaneous tissue. The characteristic features peculiar to a burn of this degree are the appearance of bubbles with a liquid of a cloudish color or with an admixture of blood. In the area of ​​damage, sensitivity is impaired, that is, the victim does not feel pain within him.
  • 2 degree. In this case, the lesion affects, in addition to the upper layer of the skin, also its deeper layers. Characterized by a burn of this degree manifestations in the form of swelling and redness, in addition, there are also fluid-filled transparent bubbles.
  • 1 degree. Only the upper layer of the skin is affected. Among the main manifestations that accompany this type of burn, a small amount of swelling and reddening of the skin is noted. In addition to this, light lesions also appear in the lesion area.

It is noteworthy that the signs of a chemical burn do not fully manifest themselves immediately, therefore it is possible to assess their degree only after first aid is provided. The first symptom is a burning pain in place where a chemical has got, and slight redness. If you do not start immediately, the burn will go from 1 degree to 2 and even 3, since the substance continues to act, penetrating deeper into the layers of tissue.

First aid for chemical burns

At home, first aid for chemical skin burns includes: the rapid removal of a chemical from the affected surface, a reduction concentration of its residues on the skin due to abundant washing with water for 15-30 minutes, cooling the affected areas in order to reduce pain.

  1. Whenchemical burns with acidfor neutralization use 2-3% solution of baking soda.
  2. With burnsalkalis- 1-2% solution of citric, boric or acetic acid.
  3. With burnslimefirstly, the remnants of lime are removed by a dry route and only then the affected area is washed away for a long time and vigorously.
  4. With burnsphosphorusIt is necessary to dump burning clothing or throw on a burning surface any cloth moistened with water. Extinguish the flame of phosphorus with a tap water or a 1-2% solution of copper sulfate. Tweezers remove all visible particles of phosphorus, after which a burnt cloth is applied to the burned surface, which is heavily moistened 2% solution of copper sulfate, 5% solution of bicarbonate soda or 3-5% solution of potassium permanganate.

Then you can apply a sterile bandage of gauze, but not from cotton wool - it can not be used. In the process of neutralizing a chemical agent, the victim carefully removes clothing that contacts the burnt area, watches and ornaments. To reduce the inflammatory process, the affected area of ​​the skin is washed with cool water, and the victim must be given a strong analgesic (pain occurs right up to loss of consciousness).

With a chemical burnseek emergency medical attention, if:

  1. The victim has signs of shock (loss of consciousness, pallor, shallow breathing).
  2. The victim feels severe pain, which can not be removed with the help of OTC analgesics, for example, acetaminophen or ibuprofen.
  3. The chemical burn spread deeper than the first layer of skin and covers a patch with a diameter of more than 7.5 cm.
  4. The eyes, arms, legs, face, groin area, buttocks or large joint are affected, as well as the mouth and esophagus (if the victim drank a chemical).

When going to the emergency room, take a container with a chemical substance or a detailed description for identification. The known nature of a chemical substance makes it possible, when rendering assistance in a hospital, to neutralize it, which is usually difficult to produce in a domestic setting.

Chemical burn of the esophagus

It may happen that a chemical substance has entered the esophagus and stomach. This can be done intentionally or be an accident. Very often such substances are battery electrolyte and acetic essence.

Rarer cases include ingestion of alkalis or concentrated acids into the esophagus and stomach. The victim has severe pain in the mouth, throat, esophagus, larynx and stomach. If the larynx is affected, the patient may feel a shortage of air. There is vomiting with bloody mucus and pieces of the stomach mucosa, which is separated due to a burn.

Since this kind of burns spread very quickly, the patient needs immediate first aid, which first of all involves washing the stomach. It can be washed with a solution of baking soda, if it is a burn acid, or a weak solution of acetic acid for burns with alkalis. In this case, a person should be given a drink not just a large, but really a huge amount of liquid, which will make it possible to completely get rid of the chemical component.

With such burns, you should call the emergency doctors as soon as possible or take the patient to the hospital yourself.

Chemical eye burn

A chemical eye burn is always considered a difficult situation from the point of view of treatment in ophthalmology. Everything depends on the degree of damage, on the agent, on the depth of penetration. Such a burn can sometimes lead not just to weakening the sight, but even to its complete loss.
  • Chemical eye burn acid is the most "light" in treatment compared to other types of agents.
  • The chemical burn of the eye with alkali is complicated in the treatment by causing hydrolysis of the structure of the protein itself, which destroys the cells and can quickly lead to moist necrosis. It is able to affect the intraocular fluid and significantly increase the intraocular pressure.

In case of chemical eye burn, as a first aid, a profuse washing should be done and the specialist should be urgently contacted, it is better to call an ambulance.

Thermal skin burn

Thermal burns are caused by fire, steam, hot water (boiling water), sun rays, etc. The most common thermal burns are from fire, they are 84 per 1000 injured. The second place is occupied by thermal burns, obtained from hot liquids, the third place - electric burns.

Such burns are of three degrees:

  • I degree- redness of the skin, swelling of the skin;
  • II degree- the appearance on the site of a burn of bubbles filled with a clear liquid;
  • III degree- Thermal burns of the third degree are divided into two types: IIIA (dermal, damage to the upper layers of the skin) and IIIB (necrosis of all layers of the skin when a necrotic scab is formed).
