Objective: Retrograde infections often occur with excessive or incomplete drainage of exudate, or as a result of adherence of dressings to wounds. Dialkylcarbamoyl chloride (DACC) irreversibly binds to bacterial surfaces and physically removes bacteria when dressings are changed. Chlorhexidine acetate-soaked paraffin gauze provides a moist wound-healing environment. We hypothesise that when DACC is combined with chlorhexidine acetate-soaked paraffin gauze, wound healing times decrease.
Method: From January 2013 to June 2015, medical records were retrospectively evaluated in 60 patients who underwent split-thickness skin grafts (STSG). Patients were divided into two groups: a 'thick skin group' and a 'thin skin group'. These two groups were further subdivided into a control group, where conventional foam dressings were applied to wounds, and an experimental group, where chlorhexidine acetate-soaked paraffin gauze with DACC was applied (DACC group). We compared the wound healing time between these subgroups. Differences in infected wound healing times were also compared. The Mann-Whitney test was applied to compare wound healing times between groups.
Results: Epithelialisation duration was significantly shorter in the DACC group. The control group had longer wound healing times, regardless of wound size. In the thick skin group, the median healing duration was 12 days in the control subgroup, compared with 9.5 days in the DACC subgroup (p=0.049). In the thin skin subgroup, the median healing duration in the control group was 18 days, compared with 10 days in the DACC subgroup (p=0.013).
Conclusion: Application of DACC and chlorhexidine acetate-soaked paraffin gauze to skin graft donor sites can shorten healing times and is effective in treating infected wounds.
