糖尿病足是糖尿病的远期严重并发症之一，其特点表现为病因复杂、治疗难度大、病情发展迅速，具有较高的致残率和致死率。患者足部溃疡未得到及时有效处置时，易出现局部伤口感染，一旦出现肌筋膜间隙感染且未能及时减张引流时，感染会迅速蔓延和播散，引发足部肿胀加重或坏疽，甚至发生全身感染危及生命。因此，本文通过回顾开放清创技术、封闭负压引流技术及小切口对口引流技术3种清创引流的方法，详细阐述这3种清创引流方法用于保全糖尿病足肌筋膜间隙感染患者肢体的具体技术要点、技术优势及技术重点，为糖尿病足多学科团队制定科学、适宜的治疗方案提供参考依据，以期促进糖尿病足溃疡患者的早期恢复及确保整体治疗的有效性。

Diabetic foot is one of the long-term and serious complications of diabetes. It is characterized by complex etiology, great difficulty in treatment, rapid development of the disease, and has high disability and mortality. When patients with foot ulcers are not treated in time and effectively, local wound infection is easy to occur. Once myofascia space infection occurs and tension reduction and drainage is not timely, the infection will spread and spread rapidly, causing foot swelling or gangrene, and even systemic infection endangering life. Therefore, this article reviews the debridement drainage methods of the open debridement, vacuum sealing drainage and small incision counterpart drainage technology, elaborates the specific technical points, technical advantages and technical focus of the three debridement and drainage methods for preserving limbs in patients with diabetic foot with myofascial space infection, to provide a reference for diabetic foot multidisciplinary team to formulate a scientific and appropriate treatment plan, in order to promote the early recovery of diabetic foot ulcer patients and ensure the effectiveness of the overall treatment.
