Clinical efficacy of dialkylcarbamoylchloride‐coated cotton acetate dressing versus combination of normal saline dressing and 2% mupirocin ointment in infected wounds of epidermolysis bullosa

Dialkylcarbamoylchloride (DACC)‐coated cotton acetate dressing works directly through hydrophobic interaction to reduce the number of bacteria without the risk of resistance. It is easy to use and therefore expected to improve patient's compliance. This study aimed to assess the clinical efficacy of DACC‐coated cotton acetate dressing compared to a combination of normal saline dressing and 2% mupirocin ointment. A single‐blind controlled trial was conducted and included 14 infected epidermolysis bullosa (EB) wounds which were divided into two groups. Group I received DACC‐coated cotton acetate dressing, and Group II received the combination of normal saline dressing and 2% mupirocin ointment. Study results showed that the average time required for complete wound closure was 8.6 and 11.1 days in Groups I and II, respectively (p = .014), which was statistically significant. Both groups showed complete bacterial elimination on Day 3 based on negative Gram stain results and on Day 6 based on clearance of clinical manifestations (p = 1.000). This is a novel study in EB‐infected wounds, which shows that DACC‐coated cotton acetate dressing promotes faster wound closure and is as effective as the combination of normal saline dressing and 2% mupirocin ointment in eliminating bacterial infection.
