Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. When a part of the body or section of skin is injured, anaerobic bacteria – microorganisms that do not require oxygen to thrive – move into the wound site. As they begin to methodically degrade tissue, these cells release chemicals like putrescine and cadaverine as byproducts. It’s those agents that are responsible for the foul smells associated with injuries like pressure ulcers and exudating wounds. Consult your doctor and see if cleaning and dressing has to be done daily, twice or so. When it comes to most wound care regimens, doctors have several options to eliminate odor. Chief among these are advanced dressings designed specifically to combat odors. Iodosorb is a patented gel used to remove exudate and debris, which represents the bulk of the odor-producing agents in sores and ulcers. Dressings made with hydrocolloid, which are used primarily on cuts, feature industrial-grade odor absorbers like cyclodextrin. Another popular option is anything with silver, which actively absorbs toxins, fatty acids and other agents responsible for foul odors. Speak with your primary doctor about the dressing type that is best suited for your wound and its accompanying odor severity. Hope I have answered your query. Let me know if I can assist you further.
