necrotizing fasciitis
Pronunciation: NEK-roh-tie-zing fash-ee-EYE-tis
Rapidly spreading deep tissue infection involving the fascial planes, requiring emergency surgical debridement.
Full Definition
Necrotizing fasciitis is a rapidly progressive, life-threatening soft tissue infection that spreads along fascial planes. It can be classified as Type I (polymicrobial, often in diabetics or immunocompromised patients) or Type II (monomicrobial, typically Group A Streptococcus). The infection causes tissue necrosis and systemic toxicity, with mortality rates of 20-40%. Early recognition is critical as the condition requires immediate aggressive surgical debridement and broad-spectrum antibiotics. Clinical signs include severe pain disproportionate to examination findings, rapidly spreading erythema, and systemic toxicity.
Usage
