Necrotizing fasciitis (soft tissue infection)
About Necrotizing fasciitis (soft tissue infection)
A rare and life threatening bacterial infection that involves the skin and the soft tissues beneath it. The infection rapidly spreads along fascial planes, destroying the fat and muscles. At first, it can look like a common skin infection called cellulitis, making an early diagnosis difficult. Because of the extensive damage produced, the bacteria responsible for the infection are sometimes referred to as `flesh-eating` bacteria.Symptoms
May start as a red area on the skin, sometimes following an injury on puncture wound. Pain often unexpected compared to how the skin looks. Redness and swelling may spread very rapidly. Other symptoms include: general ill feeling, fever, sweating, chills, nausea, dizziness, profound weakness, weak pulse.Tests & Diagnostics
A history and physical exam will be performed. A biopsy of the involved tissue may be done to identify the disorder and isolate the bacteria causing the infection. A CT scan or MRI may be done to identify the extent of the disease. Blood cultures can also be used to identify the offending organism.Common tests: Complete blood count (CBC), Comprehensive metabolic panel (CMP), CT Scan, MRI, Urinalysis (UA), X-ray.
Conventional treatment summary
Therapy must not be delayed to prevent permanent injury and death. Intravenous broad-spectrum antibiotics must be given immediately. Surgery is required to open and drain infected areas and remove dead tissue. At times amputation is necessary. Hyperbaric oxygen therapy may be administered. Skin grafts may be needed after the infection goes away.Medical specialties
