Nutritional support in patients with chronic wounds and pressure ulcers
Abstract
In patients with chronic wounds, energy needs and some special nutritive substance requirements are increased due to intensified metabolism. It is sometimes impossible to satisfy them with usual food intake. The aim of the quantitative analysis of professional and scientific articles was to find out whether nutritional support in patients with chronic wounds is required. 18 studies and 7 professional articles on nutritional support, on the impact of certain nutritive substances on wound healing and on the recommended food intake were analysed. In the analysis of the studies the statements were evaluated on a scale from 1 – 4, while the grade of recommendation was rated from A to D. The analysis of the literature revealed that many of the patients with chronic wounds are insufficiently nourished or undernourished. In undernourished patients wounds heal more slowly and the risk of development of pressure sores is increased. The analysis also revealed that nutritional support in patients with chronic wounds is required and that it enhances healing of wounds. In spite of the existence of many different studies it is still not easy to find data and recommendations on the nutrition of patients with chronic wounds. The majority of the studies deal with the patients with pressure sores and with the patients with massive burns. Because the patients get several nutrients in nutritive support it is hard to estimate whether better healing is the consequence of the addition of one nutrient or of several of them.Downloads
