Background
Foul-smelling, non-healing wounds are common among hospice and palliative care patients with advanced illnesses — including those with pressure ulcers, vascular disease, or tumors. Odor can deeply affect patients’ self-esteem, social interactions, and emotional well-being, often making them feel isolated¹. This issue provides a concise overview of effective, evidence-based strategies for reducing and masking wound odors.
Understanding the Cause
Wound odor typically results from anaerobic and gram-negative bacteria producing malodorous by-products. Even without deep infections, these bacteria can cause significant odors.
Addressing the Cause of Odor
1. Cleanse the Wound²
- Remove necrotic tissue using mechanical debridement (e.g., wiping with moistened gauze).
- Use wound cleansers with hypochlorous acid to reduce bacteria and fungi.
- For strong odors, use 0.125–0.25% sodium hypochlorite solution.
- Preservative-free, room temperature normal saline is similar in efficacy and safety as a non-irritating agent
2. Control Infection
- Metronidazole: used off-label to reduce odors by working as an anti- inflammatory as well as an anti-infective agent against anaerobic bacteria³. It is available in the following preparations. Commercially available topical gel (0.75% and 1%) Applied once or twice daily Costs can range from $120-$150 Crushed oral tablets – sprinkled into wound and covered with dressing Significantly more cost effective than gel ($0.45 per tablet) Applied once or twice daily Compounded metronidazole 5% topical powder Alternative to crushed tablets Injection solution soaked in gauze or dressings Systemic Metronidazole Reserved for deeper or systemic, more severe infections
- Topical Silver Sulfadiazine: Reduces odor in superficial wounds⁴⁵ (~$20).
- Cadexomer Iodine: Offers slow-release antimicrobial action and absorbs exudate—ideal for odorous, draining wounds.
- Natural Options: Medical-grade honey: Bactericidal and may reduce both odor and pain⁵.
Hiding the Odor
Aromatics
- Use essential oils, peppermint, coffee grounds, or cider vinegar to neutralize odors in rooms. Oils are applied to the outside of the wound dressing.
- Avoid strong perfumes that may irritate patients.
- Immediate disposal of saturated dressings will also assist in odor control.⁶
Adsorbents
- Activated charcoal (briquettes or dressings) effectively absorbs odor.
- Baking soda between dressings can help.
- Cat litter can also serve as a low-cost alternative for room odor control.
Support & Education
Odorous wounds can cause embarrassment, shame, and isolation.
- Encourage psychological and spiritual support for patients and families.
- Educate caregivers on wound cleaning, odor management, and emotional sensitivity.
- Healthcare professionals should remain composed—avoid showing distress in front of patients.

Final Note
Wound odor is more than a clinical challenge — it’s an emotional one. It can quietly erode a patient’s confidence, strain family visits, and weigh on caregivers who feel they’re never doing enough. Addressing it well isn’t just about choosing the right cleanser or dressing; it’s about preserving dignity in the small, everyday moments of care.
For hospice teams, those moments define the quality of the experience — for patients, for families, and for staff. Every gentle approach, every small improvement in comfort, is an act of respect that carries further than we often see.
