Cross-section diagram of human skin showing burn depth by degree, with arrows indicating that first-degree burns affect only the epidermis, second-degree burns reach the dermis, third-degree burns extend into subcutaneous tissue, and fourth-degree burns penetrate to muscle. — burn This diagram shows how burn injuries are classified by severity. First-degree burns damage the outer skin, known as the epidermis. First-degree burns are the least severe form of burn injury. Second-degree burns damage the outer skin and some of the underlying skin, known as the dermis, which also includes some connective tissue. Third-degree burns damage all the layers of skin, including subcutaneous tissue. Fourth-degree burns, which are the most severe, destroy every layer of skin and also damage muscle, tendons, and bones.

To treat fluid loss during the first 24 hours following a severe burn, burn centers prioritize the management of burn shock through aggressive fluid resuscitation.1

The primary method involves the intravenous administration of a balanced salt solution, such as Ringer’s lactate. This solution is essential to replace the fluids lost directly into the burn wound and those lost from the wound into the surrounding environment. Because the primary loss from burns consists of plasma and electrolytes, these components must be replaced in proportion to the patient's size and the extent of the burn area.12

To ensure this resuscitation is effective, medical teams implement several monitoring procedures:
* Intravenous lines: These are placed to administer the necessary fluids and to monitor the resuscitation process.1
* Bladder catheterization: A catheter is inserted into the bladder to track urine output, which serves as a key indicator of successful fluid resuscitation.1
* Diuretics: If necessary, diuretics such as mannitol may be used to stimulate urine output and protect the kidneys from potential damage caused by hemolysis.1
