This article gives an overview of the treatment and causes of venous leg ulcers and focuses on a new four-layer bandage system (K-Four from Parema) which can be used in the treatment of these ulcers. The article features preliminary observations of this new system, which was used on 10 patients who had previously worn multilayer compression.
Research and development in wound healing has ensured that issues relating to chronic wound management remain high in the nursing agenda. Since the advent of modern wound dressings, which retain a moist wound healing environment, work has continued to progress into more advanced, interactive products which aim to alter the wound bed in order to promote a suitable environment for cell migration and growth. Rapid wound healing is advocated and necessary to reduce morbidity and mortality in patients with large chronic wounds and to reduce the financial and manpower implications of long-term wound care in the hospital or community setting. Vacuum-assisted closure, artificial skins, growth factors and larval therapy are discussed in order to give an overview of some of the emerging practices being adopted for difficult to manage wounds.
The Tielle family (Johnson & Johnson Medical) is a range of dressings that come in a variety of shapes and sizes, designed to fit the different types and locations of wounds that occur in practice. There are three types--Tielle, Tielle Lite and Tielle Plus--and the choice of dressing should be based on the degree of exudate that the wound is producing. This product focus aims to give an overview of the range and provides research-based evidence for application in clinical practice.

The realisation that pressure sores are caused by shearing forces and tissue distortion rather than simply by pressure, had led to the development of specialised patient support systems. The pulsating air suspension system was developed to help reduce the incidence of oedema formation. All health-care professionals using specialised bed therapy have a responsibility to understand the principles of that therapy in order to ensure appropriate patient selection, which may be aided by the development of placement criteria. The concept of pulsation therapy has been a stimulus for new thinking on the causes and treatment of pressure sores and has highlighted the need for further research on the part played by the lymphatic system and oedema on pressure sore formation, although there is already strong evidence that there is a link between tge two.
