Experience with local negative pressure (vacuum method) in the treatment of complex wounds.
OBJECTIVE
Use of topical negative pressure over difficult-to-heal wounds has been studied. The objective of this study was to analyze the effects from negative pressure in the treatment of complex wounds.


METHODS
Case series developed at Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo.


METHODS
Twenty-nine patients with complex wounds were treated with the vacuum system and then underwent a surgical procedure to close the wound.


RESULTS
85% of the skin grafts took well, and 87.5% of the local flaps were successful, thus demonstrating adequate wound preparation. The wounds were closed within shorter times than observed using other conventional treatments In two cases, the vacuum system was also used to stabilize the skin grafts over the wounds.


CONCLUSIONS
Use of the vacuum method is safe and efficient for preparing wounds for surgical closure. It allows for an improvement of local wound conditions, and healthy granulation tissue develops with control over local infection.
