Wound healing of open fractures: comparison of vaccum assisted dressing versus traditonal dressing

For permanent wound coverage of compound fractures, the wound surface should have 100% granulation tissue without any discharge or necrotic slough. Negative pressure wound therapy (NPWT) is a well known modality in the management of open fractures, and post-operative wound problems. This study was conducted to compare the outcome of NPWT and traditional dressing in wound healing of open fractures.

A prospective study of 100 cases was conducted to compare the wound healing outcomes of open fracture following vacuum assisted closure (VAC) dressing (50 cases) and traditional wound dressing (50 cases). Patients included in the study underwent initial debridement to remove necrotic slough and tissue when indicated. Foam dressings were used to cover the wounds using aseptic conditions in the VAC group. Dressings were changed daily for patients in traditional dressing group using hydrogen peroxide, normal saline and povidone iodine in a sequential manner and every 3-4 days in the VAC dressing group. Patients were evaluated clinically for appearance of granulation tissue, duration of hospital stay and reduction in wound surface area using appropriate statistical methods.

There was a significant difference between the rate of wound healing in the group NPWT/VAC group compared to the traditional wound dressings group in terms of appearance of granulation tissue, reduction in wound surface area and duration of hospital stay.

Vacuum assisted dressing is more effective than traditional wound dressing in wound healing of open fractures.
