title: Approach to debridement in necrotizing fasciitis.
abstract: Aggressive debridement is a cornerstone intervention in necrotizing fasciitis. Our approach consists of 4 steps: (1) confirming the diagnosis and isolate the causative organism; (2) defining the extent of fasciitis; (3) surgical excision; and (4) post-excision wound care. The extent of the infection is defined by probing the wound bluntly. Systematic excision follows. Fascial excision must be complete and uncompromising with the full extent of the involved wound laid open. We classify the infected skin into zones 1, 2, and 3. Zone 1 is necrotic tissue. Zone 2 is infected but potentially salvageable soft tissue, and zone 3 is non-infected skin. Zone 1 is completely excised. Zone 2 is meticulously assessed and cut back as necessary to remove nonviable tissue while maximally preserving salvageable tissue. Zone 3 is left alone. The aim of surgical debridement is to remove all infected tissue in a single operation. This halts the progression of the fasciitis and minimizes unnecessary returns to the operating room.
