(CS-050) Mechanically Powered Disposable Negative Pressure Wound Therapy Use in Three Patients

Introduction: Electrically powered negative pressure wound therapy (NPWT) is commonly utilized in complex wounds; however, this therapy requires electrical power, is noisy, and can interfere with patient ambulation. Another option available is mechanically powered disposable NPWT (dNPWT*). dNPWT can be utilized in patients with small to medium sized wounds, does not require electrical power, and is quiet and lightweight.^1,2 In patients with small to medium sized wounds requiring NPWT, dNPWT may provide clinicians another therapy option. Use of dNPWT in 3 patients was examined.

Methods: Antibiotics were given as needed. dNPWT was applied with dressing changes every 2-3 days. Advanced wound dressing use was initiated in 2 patients after dNPWT was discontinued.

Results: Three patients (age 52-78 years) presented for care. Wound types included dehiscence (n=2) and pressure injury (n=1). Patient medical history included hypertension, diabetes, peripheral vascular disease and previous amputation. Wound area reduction was observed in all 3 patients. After 21-28 days, dNPWT was discontinued. Complete wound healing was observed in 2 patients. Unfortunately, the remaining patient expired before wound healing was observed; this was unrelated to the patient’s wound care

Discussion: The use of dNPWT in these 3 patients contributed to complete wound healing in 2/3 patients and wound area and volume reduction in the remaining patient.
