Abstract:

Non-clostridial organism can produce pneumoderma by breaking down sugar and other substrates in necrotic tissues, and non-clostridial gas-forming infection is usually seen in diabetic patients with poor glycemic control. The differential diagnosis between clostridial and non-clostridial gas-forming infection relies on etiological examination results, but the key to successful treatment is timely empiric broad-spectrum antibiotic treatment and emergency surgical debridement in the absence of a definitive etiologic diagnosis. This paper reported two cases of non-clostridial gas-forming infection in diabetes, and reviewed relevant literature, aiming to improve clinicians' understanding of this disease.

摘要：

非梭状菌可分解坏死组织中的糖等底物并产生皮下气肿，而非梭状菌皮肤软组织产气性感染常出现在血糖控制不佳的糖尿病患者中。非梭状菌与梭状菌引起产气性感染的鉴别诊断依赖病原学检查结果，但在未取得病原学证据之前早期、联合使用广谱抗生素和及时、有效地清创及必要的手术是救治糖尿病合并非梭状菌皮肤软组织产气性感染患者的关键。本文报道了2例糖尿病合并非梭状菌皮肤软组织产气性感染患者并进行了文献复习，以期提高临床医生对该病的认识。
