VAC and Conventional Dressing in the Healing Process of Necrotizing Fasciitis

Overview

Find out the best management of Necrotizing Fasciitis after surgical debridement

Necrotizing fasciitis is a life-threatening condition that can occur as a result of trauma or foreign bodies in surgical wounds as well as idiopathically. Necrotizing fasciitis is characterized by a progressive infection in fascial planes with necrosis of the subcutaneous tissue. Necrotizing fasciitis affects the extremities more frequently than central areas. Risk factors for necrotizing fasciitis include diabetes mellitus, trauma wound infections, decubitus ulcers, alcoholism, carcinoma, peripheral vascular disease, smoking, and intravenous drug abuse. A varieties of micro-organisms, including gram-positive group A streptococcus, haemolytic streptococci, and staphylococcus aureus; gram-negative Enterobacteriaceae, Escherichia coli, Klebsiella spp., and Proteus spp.; anaerobes including Peptostreptococcus, Clostridium, and Pacteroides; and fungi such as Candida and acid-fast bacteria have all been implicated in the pathogenesis of Necrotizing fasciitis. Necrotizing fasciitis is a surgical emergency for detoxification by debridement with good antibiotic coverage. It has mortality rate reaching 20-30% , this mortality rate is high and requires prompt diagnosis, antibiotic treatment and extensive necrosectomy up to intensive care units admission in some cases, the aim of our prospective analysis is to assess with a hypothesis-generating and exploratory purpose the possible role of VAC versus ordinary dressings in the wound therapy of Necrotizing Fasciitis in terms of expected time for wound closure and survival rate.
