Dressings contain pure activated carbon impregnated with silver (33 and 25 ug/cm2 respectively), enclosed in a non-adherent nylon sleeve. The charcoal traps odour in the dressing, binds bacteria and toxins that impair the healing process. Silver controls a wide range of bacterial, fungal and viral pathogens that can occur in a wound. Malodour is one of the most distressing symptoms for patients. It can cause depression and social isolation, which may impact on social and family relations for the patient. Through eliminating offensive odours, dressings lead to an improvement in quality of life for a patient and clinician.
