Velcro compression wraps as an alternative form of compression therapy for venous leg ulcers: a review.

The first-line treatment for venous leg ulcers (VLUs) is compression therapy, most commonly, with compression bandages. A similar treatment measure is used for lymphoedema in the form of Velcro compression wraps (VCWs). However, the use of VCWs for VLUs is less evident, and a direct comparison to compression bandaging is not evident. This review explores the evidence to support the use of VCWs for the treatment of VLUs in order to raise awareness of alternative forms of compression therapy. Nine primary research studies were analysed, from which four key themes emerged: quality of life, cost of treatment, ulcer healing time and pressure maintenance. The findings suggest that VCWs decrease material costs by at least 50%, and further savings may be realised by reducing the costs associated with nursing time. The benefits of promoting self-care, maintaining compression, and eliciting greater healing rates are clearly evident, and the impact on quality of life is substantiated.

The influence of matrix metalloproteases and biofilm on chronic wound healing: a discussion.

Chronicity in wound healing is a challenge for health services financially and scientifically, with negative consequences on patients' lives. This paper seeks to explore why chronic wounds fail to heal in relation to the inflammatory cellular dysfunction associated with biofilm development. Findings demonstrate an association between chronic wounds failing to heal, the presence of devitalised tissue and abnormal immune cell activity with a consequential excessive release of harmful matrix metalloproteases (MMPs). This process perpetuates the cycle of wound chronicity and extracellular matrix destruction, which prolongs the inflammatory response, fuelling biofilm formation. Evidence suggests that 'trapping' MMPs may increase new tissue growth but, while devitalised tissue is present, phagocytic cells continue to secrete MMPs and chronicity persists. Consequently, by removing the trigger and implementing effective, sustained debridement of devitalised tissue, both MMP and biofilm production will be diminished, with positive healing outcomes.
