Necrotizing fasciitis (NF) is an infection that affects the facial planes causingsubcutaneous tissue death, characterized by rapidly progressive,systemic toxicity and even death. The FN appears as a red, painful, withincreased temperature, swollen wound and ill-defined border. With progressionof the infection process local pain is replaced by numbness oranalgesia. Initially the skin look pale, then mottled and purple and thenfinally acquires a gangrenous appearance. FN's ability to fast forwardthrough the fascial planes and cause tissue necrosis is due to the polymicrobialcomposition and the synergistic effects of the enzymes producedby bacteria. The treatment of this disease involves securing the airway,therapies with broad-spectrum antibiotics, intensive care, support andrapid surgical debridement repeating the process as often as necessary.The reduction in mortality from FN depends on early diagnosis and applicationof a quick and aggressive treatment.
