Malodours are a common complication of chronic wounds. They are the result of the proliferation of aerobic and anaerobic micro-organisms on the wound surface, where they metabolize healthy tissue which leads to the production of sloughy and even necrotic tissue. Wound odour has a big impact on the quality of life of patients.

Currently the standard of care for the management of malodourous wounds are systemic antibiotics, absorbent wound dressings with or without activated carbon and, topical antimicrobials. The application of topical antimicrobials such as antiseptics against wound odour is part of the standard care. One suggested antiseptic in a recent published standard is Octenilin®. There is ample anecdotal evidence about the efficacy of Octenilin® in reducing wound odour. Therefore, we propose here to document this ability by evaluating the odour of wounds washed with Octenilin® versus standard care (NaCl 0.9% solution).

They are the result of the proliferation of aerobic and anaerobic micro-organisms on the wound surface, where they metabolize healthy tissue which leads to the production of sloughy and even necrotic tissue. Wound odour has a big impact on the quality of life of patients. Patients describe living with a chronic malodourous wound as devastating particularly in respect to social interaction. The key to addressing the negative consequences of malodorous and/or discharging wounds is an effective wound managements plan based on accurate and holistic assessment of the patient and the wound.

The application of topical antimicrobials such as antiseptics against wound odour is part of the standard care. One suggested antiseptic in a recent published standard is Octenilin®. Octenilin® wound cleansing solution is on the Swiss market since 2006 and is routinely used in outpatient wound care centers. It exhibits good performance in the reduction of biofilm's pathogens and has excellent moisturizing properties. While there is ample anecdotal evidence about the efficacy of Octenilin® in reducing wound odour, we propose here to document this ability by evaluating the odour of wounds washed with Octenilin® versus standard care (NaCl 0.9% solution).
