Venous Leg Ulcer With Maceration and Pain: Rebuilding the Plan of Care
Mr. T is a 72-year-old man with a 6 x 4 cm venous leg ulcer on the medial malleolus, present for 5 months. The wound bed is 70% slough and 30% granulation, with moderate-to-heavy serous exudate and no odor. The periwound skin is macerated and has brown hemosiderin staining. ABI is 1.02. He has 2+ pitting edema to mid-calf. Pain is 6/10 during dressing changes, worse when the gauze is removed. Current order: daily wet-to-dry gauze with povidone-iodine, no compression, keep leg dependent. He is afebrile. He says, 'I thought the iodine would kill the germs, but it's not getting better.'
1. Critique the current plan and explain the physiologic rationale for your concerns.

Problems with the current plan:
- Wet-to-dry gauze is nonselective: it strips healthy granulation and causes pain when removed, and it does not manage heavy exudate well.
- Povidone-iodine can be cytotoxic to healing tissue, especially with prolonged use on a clean wound. There is no evidence of infection here (no odor, no purulence, no fever), so antimicrobial treatment is not the priority.
- No compression is the major error. Venous ulcer healing depends on controlling venous hypertension and edema. With ABI 1.02, compression is generally appropriate after assessing for contraindications such as significant heart failure.
- Leg dependency worsens edema and venous pressure.
- Slough and exudate need moisture balance and debridement, not repeated drying and wetting.
Conclusion: The wound is not failing because iodine is weak; it is failing because the underlying venous disease and moisture imbalance are unaddressed.
2. Select an appropriate dressing regimen and compression strategy for this week. Justify each choice against the wound characteristics.

Cleansing and debridement: Cleanse gently; perform conservative sharp debridement of slough if within scope and ordered. Debridement reduces bacterial burden and allows granulation.
Dressing: Use a moisture-managing primary dressing for moderate-to-heavy exudate, such as a hydrofiber or superabsorbent dressing, covered with a foam or absorbent secondary dressing. Avoid gauze and avoid occlusive films over wet slough. The goal is to absorb excess exudate without desiccating the wound bed.
Compression: With ABI 1.02 and no heart failure contraindication, start graduated multilayer compression bandaging. Compression reduces edema, improves venous return, and is the foundation of venous ulcer healing. Ensure the bandage is applied by a trained clinician and check for pain, numbness, or color change.
Adjuncts: Elevate the leg above heart level when resting, encourage ankle movement and walking, and premedicate before dressing changes.
3. How would you manage the pain and periwound maceration, and what education would you provide?
Read the worked answer
Pain: Give analgesia 30 to 60 minutes before dressing changes. Use gentle technique, moisten adherent dressings rather than pulling them dry, and avoid wet-to-dry gauze. Assess pain score before and after and document the response. If pain remains severe, request a wound-care or pain consult.
Maceration: Protect periwound skin with a barrier film or zinc-based protectant before applying the dressing. Choose an absorbent dressing with a margin that does not trap moisture on intact skin. Reassess edema control, since maceration will persist if exudate and venous hypertension are not controlled.
Education: Explain that compression, not iodine, treats the cause. Teach elevation, walking, skin inspection, and when to call for increased pain, fever, odor, or color change. Use teach-back and document understanding. Set a realistic timeline with weekly measurements.
