Association of Negative Pressure Wound Therapy and Dermatotraction for Management of Necrotizing Soft Tissue...

Soft tissue infections (STIs), which include infections of the skin, subcutaneous tissue, fascia, and muscle, encompass a wide variety of heterogeneous pathologies. Treatment of STIs is based on surgical debridement of the affected area. One such treatment, negative pressure wound therapy (NPWT), has improved the management of STIs.

The purpose of this study is to assess the safety and utility of NPWT in conjunction with dermatotraction in the early stage management of necrotizing STIs.

The authors report a retrospective series of 3 cases in which NPWT and dermatotraction (NPWT-D) were used in an attempt to manage necrotizing STI. The NPWT-D device combination was employed to approximate the edges of the wounds. The NPWT device was changed every 2 or 3 days, and dermatotraction tension was adjusted concurrently.

The NPWT-D device changes ranged from 3 to 4 times for 2 of the 3 patients, as 1 patient passed away secondary to STIs and therefore did not receive complete treatment. The total treatment ranged from 8 to 10 days in the remaining 2 patients. In both cases, complete wound closure was achieved while avoiding skin grafts. After 5 days of therapy in the incomplete treatment case, the wound area was reduced by about half.

Based on the experiences herein, NPWT-D may be a safe and useful alternative surgical treatment for the management of necrotizing STIs. In the present cases, NPWT-D improved and shortened the wound healing process, and it achieved a tertiary wound closure, thereby avoiding the need for skin grafts.
