It feels like gas moving around in the tissue, which is why myonecrosis is sometimes called gas gangrene.

它摸起来像是气体在组织内游走，这也是肌坏死常被称为气性坏疽的原因。

And since untreated gas gangrene can spread rapidly, the diagnosis is usually made based on the severity of the infection and on how quickly it spreads.

且由于未经治疗的气性坏疽进展迅速，诊断常常基于感染严重程度及进展速度得出。

Having said that, the diagnosis can be confirmed with an anaerobic tissue culture, but that usually takes a few days, which is far too long for individuals with gas gangrene.

虽说可通过厌氧菌培养确诊，但培养需要几天，对气性坏疽患者来说不够及时。

If Clostridium perfringens gets into an open wound, it can cause clostridial myonecrosis, or gas gangrene, which can be deadly within hours without surgical excision of the necrotic tissue, along with penicillin V and, in some cases, hyperbaric therapy.

如果产气荚膜梭菌感染开放性创口，会导致梭菌性肌坏死，即气性坏疽；若没有对坏死组织做外科处理，数小时内可能致死；一般采用青霉素V治疗，有时用高压氧治疗。
