Diabetic foot ulcers (DFUs) are at significant risk of becoming infected, with an associated elevated risk of amputation. Choosing an appropriate treatment would help prevent infection, improve healing and patients' quality of life, as well as reduce healthcare costs. The aim of this study was to assess the efficacy of a dialkylcarbamoyl chloride (DACC)-coated wound dressing to reduce bacterial load in the treatment of infected diabetic foot ulcers with signs of biofilm.
In this prospective, descriptive observational study, patients with infected DFUs were treated with a DACC-coated wound dressing, and were followed until complete healing was achieved. Levels of bacterial load and the presence of biofilm were also assessed.
The patients consisted of 42 males and 19 females, with a mean age of 54.4 years. All wounds exhibited complete wound closure upon treatment with the DACC-coated wound dressing, with an average time to heal of 71.8 days. A total of 53 patients had received systemic antibiotic treatment prior to study enrolment, and the number of patients requiring antibiotic treatment reduced to 20 during the study. The level of bacterial load (including biofilm) was reduced, leading to wound progression in a proportion of wounds.
The findings of this study revealed that treatment with a non-medicated antimicrobial wound dressing was an appropriate dressing choice to reduce microbial load and aid promotion of healing in infected DFUs with the presence of biofilm.
糖尿病足溃疡(DFU)有发生感染的重大风险,截肢风险也随之升高。选择合适的治疗方法有助于预防感染、促进愈合、提高患者生活质量并降低医疗成本。本研究旨在评估二烷基甲酰氯(DACC)涂层伤口敷料在治疗有生物膜迹象的感染性糖尿病足溃疡时降低细菌载量的疗效。
在这项前瞻性描述性观察研究中,感染性糖尿病足溃疡患者接受DACC涂层伤口敷料治疗,并随访至完全愈合。还评估了细菌载量水平和生物膜的存在情况。
患者包括42名男性和19名女性,平均年龄54.4岁。所有伤口在用DACC涂层伤口敷料治疗后均实现完全伤口闭合,平均愈合时间为71.8天。共有53名患者在研究入组前接受了全身抗生素治疗,研究期间需要抗生素治疗的患者人数降至20名。细菌载量(包括生物膜)水平降低,部分伤口出现伤口进展。
本研究结果表明,使用无药物抗菌伤口敷料进行治疗是减少有生物膜存在的感染性糖尿病足溃疡微生物载量并促进愈合的合适敷料选择。
