Introduction: Disposable mechanical negative pressure wound therapy (dNPWT*) can be used to manage lower extremity wounds in the outpatient clinic. This small dNPWT provides negative pressure while allowing the patient to maintain ambulation as the dNPWT device can be worn underneath clothing. We examined the use of dNPWT in 16 patients at a podiatry clinic assessing wound healing and the development of granulation tissue. Methods: <span style="font-size: 11.0pt; line-height: 107%; font-family: 'Arial',sans-serif; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">This retrospective case series assessed the use of dNPWT in 16 patients with chronic wounds and advanced wound dressings in the treatment pathway. Patients were treated between October 31, 2019 to December 16, 2021. All patients received dNPWT treatment. dNPWT dressings were changed every 2-3 days. Demographics, baseline wound, and subsequent wound visit data and treatments were recorded. The outcome measures included area, volume, duration of treatment, and healing status.

Most wounds (87%) were healed at, or shortly after, stopping therapy with dNPWT. Trademarked Items: *3M™ Snap™ Therapy System (3M Company, St. Paul, MN) References:
