Advances in the research of application of vacuum-assisted closure in wound healing and its mechanism / 中华烧伤杂志

ABSTRACT

As a new generation of negative pressure drainage technology, vacuum-assisted closure (VAC) can provide stable and persistent negative pressure, and there are several modes to choose from. VAC plays an important role in closing wounds quickly, controlling infection, promoting angiogenesis, increasing blood flow, and promoting granulation tissue growth of wounds. It is now widely applied in all kinds of acute, chronic, and special wounds in clinic with good therapeutic results. However, we need to pay attention to contraindications and complications of VAC when it is used, avoiding secondary damage due to improper treatment. In this review, we summarize VAC dressings, treating pressure and mode choice, mechanism in promoting wound healing, and clinical application of VAC.
