RESUMEN
This case study examines the effectiveness of using negative pressure wound therapy (NPWT) in the management of a hard-to-heal (chronic) wound with exposed ankle bone to reduce associated wound exudate and promote production of granulation tissue. A 60-year-old male patient who was able to attend wound follow-up diligently twice weekly for eight weeks, and weekly thereafter, was selected from a private hospital to take part. During each dressing change, the wound was cleansed with superoxidised cleansing solution, and minimal sharp debridement was performed. In the authors' opinion, the NPWT device used in this study is light and convenient for use in the community or home care setting. The NPWT wound dressing was connected to the NPWT machine via a connecting tube and the device then switched on using the default setting of a negative pressure of 125mmHg. Following the application of the NPWT device, the exposed ankle bone was successfully covered with healthy granulation tissue and healed within 20 weeks with minimal exudate formation in the wound. In the authors' opinion, NPWT is able to promote progress to wound healing; to minimise unnecessary dressing changes and, based on feedback from the patient, is comfortable to wear and when in use.
