Third-degree burns

High urgency
-Moderately severe

Injuries that affects the deeper layers of the skin.

The most frequent causes are exposure to thermal agents, exposure to cold, chemical burns, electric current, radiation and inhalation.

We can see charred tissue, the nerve endings responsible for transmitting pain are destroyed, they do not hurt, the skin is dry (leathery appearance), scorched or with white, brown or black spots, rupture of skin with exposed fat, inflammation (oedema) and/or death of the affected tissue (necrosis).

Diagnosis is based on a detailed clinical history, complete physical examination, laboratory tests (blood and urine), electrocardiogram and radiological monitoring of the chest according to medical criteria.

Treatment should be carried out at hospital level, ensuring support measures, pain control, gastric protection, tetanus vaccination and specific measures according to the specialist's assessment.
