Dark gray or black necrotic spots on burn wounds

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

Cause

According to the local symptoms of wound infection, the performance of systemic infection after burn, the clinical characteristics of the systemic infection after burn, medical history and other aspects to diagnose. Dark gray or black necrotic spots on burn wounds are the key to the diagnosis of Gram-negative bacilli infection.

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.

Burn wounds are pale or pyrophoric: burns are pale or burnt yellow is a burn of III degree. 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.

According to the local symptoms of wound infection, the performance of systemic infection after burn, the clinical characteristics of the systemic infection after burn, medical history and other aspects to diagnose. Dark gray or black necrotic spots on burn wounds are the key to the diagnosis of Gram-negative bacilli infection.
