Cleansing Versus Tailored Deep Debridement, a Fresh Approach to Wound Cleansing: an Italian experience

Abstract

Objective: To evaluate if cleansing, using a solution containing the antimicrobial polyhexanide and the surfactant betaine (polyhexanide propylbetaine [PP], Prontosan Solution, B. Braun), can aid effective wound bed preparation (WBP).

Method: A solution containing the PP was used in two different treatment regimens. Group A was treated with a single application at different time durations (2, 5, 10 and 15 minutes) to evaluate efficacy in the removal of residues from the wound bed. Group B was treated with PP for 10 minutes, followed by application of an inert dressing, at daily dressing changes for 14 days, to evaluate efficacy of debridement.

Results: A total number of 70 patients took part in the study. In Group A (n=40), after the two and five minute application, no change was observed. At 10 minutes, an improvement was seen in 4/10 cases and at 15 minutes the improvement was in 5/10 patients. In Group B (n=30), over the 14 days, an improvement in the condition of the tissue, i.e. the wound bed was cleaned and debrided in 73% of cases, was observed. Patients experienced a reduction in pain and no adverse effect or complication was reported. Periwound skin was improved in 29/30 cases, with only one case where the tissue deteriorated, as determined by the presence of maceration.

Conclusion: PP is effective in helping debridement during wound cleansing. Efficacy depends on time of application. However, randomisation and further study is required to confirm these results.
