Necrotizing fasciitis

Necrotizing fasciitis is a widespread and rapid soft tissue infection characterized by subcutaneous and fascial necrosis, often accompanied by systemic toxic shock. As early as 1871, American surgeon Josepoh Jones called the disease "gangrene in hospitals." Fedden described the disease in 1909 and called it "acute infectious gangrene"; Mcafferty et al. Later called the disease "purulent fasciitis"; in 1924, Meleney named the disease "hemolytic streptococcal gangrene"; 1952 Wilson suggests that progressive gangrene of superficial and deep veins under the skin is collectively referred to as acute necrotizing fasciitis. Unlike streptococcal necrosis, this disease is a mixed infection of multiple bacteria, mainly aerobic bacteria such as Streptococcus pyogenes and Staphylococcus aureus. The infection of this disease only damages the subcutaneous tissue and fascia, and the muscle tissue that does not affect the infected site is an important feature.
