Pale or charred burn wounds

Introduction The classification of burns is currently widely used in China. The degree of burn is divided into I degree, shallow II degree, deep II degree and III degree. Clinically, I degree and shallow II degree are shallow burns, and deep II and III degrees are deep burns. Burning wounds are pale or pyrophoric charcoal is a third degree burn. Third degree burns: involving the entire layer of the skin even subcutaneous fat, muscles, internal organs. The wound is pale or burnt yellow, no pain, no blistering, feeling disappears, and the texture is tough like leather. After 3 to 4 weeks, the granule tissue was left behind after the eschar was shed, and the scar was left behind, and the skin function was lost, causing deformity. Acid burns generally do not blister and quickly become sputum. The burned sputum of sulfuric acid, nitric acid and hydrochloric acid are dark brown, yellow brown and yellow respectively; the deeper the burn, the darker the sputum, the more obvious the invagination of the sable, the harder the texture. Alkali burn wounds are sticky or sap-like eschar, color redness, small blisters, generally deep, eschar or necrotic tissue shedding, wound surface depression, edge sneak, often unhealed. In addition, acid burns are easy to estimate, and alkali burns and other chemical burns continue to deepen. The depth should be verified repeatedly. Severe burns: can affect the body tissues and organs, a series of pathophysiological processes, such as water and salt electrolyte disorders, acid-base balance disorders, shock, DIC, immune imbalance, secondary infection, cardiac insufficiency, respiratory insufficiency and so on. In particular, impaired respiratory function is one of the important causes of death.

Cause

It involves the entire layer of the skin and even subcutaneous fat, muscles, and internal organs. Caused by burns.

According to the history of burns and skin lesions can be diagnosed. According to the no water blister, only red, swollen, painful, burning sensation, edema, blister, exudate, involving the depth of skin burns.

Differential diagnosis

The viscous secretion of the sweet scent of burn wounds: After the burn, the skin is destroyed as a natural shield against microbial invasion, and the necrotic skin tissue is a good "medium" for microbial growth and reproduction. Therefore, burn wounds are extremely susceptible to infection. In recent years, shock mortality has decreased significantly due to the improvement in the level of burn shock treatment. Burn infections have become the leading cause of death from severe burns. Prevention and treatment of burn infection is the key to burn treatment. The viscous secretion of a sweet scent on a burn wound belongs to Pseudomonas aeruginosa infection.

Burning wounds light brown thin secretions: burns appear wounds light brown thin secretions are hemolytic streptococcal infections.

Burn wounds have an early tidal solution, detachment, or insect bite-like changes: eschars premature deliquescence, shedding, or insect bite-like changes indicate local infection.

Burn wounds, fecal odor secretions: burn wounds, fecal odor secretions are anaerobic infections.

Light yellow viscous secretions from burn wounds: The appearance of light yellow viscous secretions is the key to judging S. aureus infection.

Dark gray or black necrotic spots on burn wounds: dark gray or black necrotic spots on the wound surface. Necrotic plaques often occur in wounds infected with Gram-negative bacilli.

According to the history of burns and skin lesions can be diagnosed. According to the no water blister, only red, swollen, painful, burning sensation, edema, blister, exudate, involving the depth of skin burns.
