(CS-140) Case Study: A Novel Silicone Foam Dressing* for Stage 3 Pressure Injury

Introduction: This case study describes the successful closure of a stage 3 pressure injury to the right below-the-knee amputation secondary to prosthesis rubbing using a novel silicone foam dressing.* The patient had previously trialed eight topical treatments in combination with weekly sharp debridement and avoiding prosthesis use. While compliant with treatment, the patient was unable to walk for over a year due to a lack of wound closure. The patient had a history of diabetes, anemia, gout, hypertension, and high cholesterol.

Methods: The patient was transitioned to a novel silicone foam dressing* with continuation of standard of care (weekly sharp debridement in the office and thorough cleansing of wound beds during dressing changes). The silicone foam dressing* was applied directly to the wound bed without a primary filler dressing, and the patient changed the dressing 1-2x weekly for up to 41 days.

Results: After 22 days, complete closure of the wound bed was observed (Figure 1). The exudate was controlled, the silicone foam dressing* filled in the wound depth entirely, and there was no breakdown or moisture to the peri-wound with continued use. The patient noted that the dressing was easy for them to change at home.

Discussion: This case study demonstrates that the novel silicone foam dressing* is simple for patients and office staff since it does not require complex or advanced instructions. As the silicone foam dressing* did not need a primary filler dressing, this method likely reduced the overall cost of care.
