Gas gangrene in which the causative organisms are non-clostridial bacteria rather than Clostridium species. These bacteria are capable of producing gas and driving the same destructive, life-threatening tissue infection.
Implicated organisms include Escherichia coli, Proteus species, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterococcus species, and Bacteroides species.
Gas gangrene is categorised as clostridial or non-clostridial depending on the infecting bacteria. The predominantly aerobic, Gram-negative profile of non-clostridial organisms — alongside possible anaerobic components — directly determines the therapeutic strategy, which differs from classical clostridial management.
Management requires an immediate, multi-modal approach. Aggressive surgical debridement is the cornerstone, combined with broad-spectrum antibiotic therapy and further adjunctive interventions aimed at arresting the infective process. The complete regimen — including specific agents, sequence, and all components — is in the full protocol.
Arrest of the infective process and limitation of the extent of tissue necrosis, with conservation of a functional limb.
