Single use negative‐pressure wound therapy compared to standard care in patients after carbon dioxide laser surgery for hidradenitis suppurativa

Negative pressure wound therapy is a commonly used treatment modality for surgical wounds healing by secondary intention. In an open, split side study with 12 patients, we compared low negative pressure wound therapy to conventional foam dressing the first postoperative week after carbon dioxide laser vaporization of hidradenitis suppurativa lesions. The primary outcome was time to complete wound healing, comparing the two intervention sites. Secondary endpoints included perception of pain during intervention period and patient registered impact of the regimes on daily life activities. Low negative pressure wound therapy the first postoperative week tended to reduce the time to complete wound healing. Patients reported significant lower pain levels from wounds treated with a negative pressure wound device the first postoperative week. Eleven out of 12 study participants had a preference to the negative pressure wound therapy regime to a conventional regime with foam dressings.
