Enteral nutrition in the prevention and treatment of pressure ulcers in adult critical care patients.

Prevention and healing of pressure ulcers in critically ill patients can be especially challenging because of the patients' burden of illness and degree of physiological compromise. Providing adequate nutrition may help halt the development or worsening of pressure ulcers. Optimization of nutrition can be considered an essential ingredient in prevention and healing of pressure ulcers. Understanding malnutrition in critical care patients, the effect of nutrition on wound healing, and the application of evidence-based nutritional guidelines are important aspects for patients at high risk for pressure ulcers. Appropriate screenings for nutritional status and risk for pressure ulcers, early collaboration with a registered dietician, and administration of appropriate feeding formulations and micronutrient and macronutrient supplementation to promote wound healing are practical solutions to improve the nutritional status of critical care patients. Use of nutritional management and enteral feeding protocols may provide vital elements to augment nutrition and ultimately result in improved clinical outcomes.
