==Overview==
'''Gas gangrene''' is a [[bacteria]]l [[infection]] that produces [[gas]] within [[biological tissue|tissue]]s in [[gangrene]]. It is a deadly form of gangrene usually caused by [[Clostridium]] bacteria. It is a [[medical emergency]].


==Features==
{{SK}} Myonecrosis; tissue infection - Clostridial; gangrene - gas; clostridial infection of tissues; clostridial myonecrosis
Gas gangrene can cause [[myonecrosis]], gas production, and [[sepsis]]. Progression to [[toxemia]] and [[Shock (medical)|shock]] is often very rapid.
==[[Gas gangrene overview|Overview]]==


==Pathophysiology==
==[[Gas gangrene pathophysiology|Pathophysiology]]==
Gas gangrene is caused by [[exotoxin]]-producing [[Clostridium|Clostridial]] species (most often ''[[Clostridium perfringens]]''), which is mostly found in soil but also found as normal [[gut flora]], and other [[anaerobe]]s (e.g. ''[[Bacteroides]]'' and anaerobic [[Streptococcus|streptococci]]). The exotoxin is commonly found in ''C. perfringens'' type A strain and is known as [[Clostridium perfringens alpha toxin|alpha toxin]]. These environmental bacteria may enter the muscle through a wound and go on to proliferate in necrotic tissue and secrete powerful toxins. These toxins destroy nearby tissue, generating gas at the same time.


A gas composition of 5.9% hydrogen, 3.4% carbon dioxide, 74.5% nitrogen and 16.1% oxygen was reported in one clinical case.<ref>{{note|Chi}}{{cite journal | author=Chi CH, Chen KW, Huang JJ, Chuang YC, Wu MH | title=Gas composition in Clostridium septicum gas gangrene | journal=J Formos Med Assoc | year=1995 | pages=757-9 | volume=94 | issue=12  | id=PMID 8541740}}</ref>

==Treatment==
==Treatment==
Treatment is usually [[debridement]] and [[excision]] with amputation necessary in many cases. [[Antibiotic]]s alone are not effective because they don't penetrate [[ischemic]] [[muscle]]s enough to be effective. However, penicillin is given as an [[adjuvant treatment]] to surgery. In addition to surgery and antibiotics, [[hyperbaric oxygen therapy]] (HBOT) is used and acts to inhibit the growth of and kill the anaerobic C. perfringens.
