severe burn causes significant metabolic derangements that make nutritional support uniquely important and challenging for burned patients. burn injury causes a persistent and prolonged hypermetabolic state and increased catabolism that results in increased muscle wasting and cachexia. metabolic rates of burn patients can surpass twice normal, and failure to fulfill these energy requirements causes impaired wound healing, organ dysfunction, and susceptibility to infection. adequate assessment and provision of nutritional needs is imperative to care for these patients. there is no consensus regarding the optimal timing, route, amount, and composition of nutritional support for burn patients, but most clinicians advocate for early enteral nutrition with high-carbohydrate formulas.
severe burn causes significant metabolic derangements that make nutritional support uniquely important and challenging for burned patients. burn injury causes a persistent and prolonged hypermetabolic state and increased catabolism that results in increased muscle wasting and cachexia. metabolic rates of burn patients can surpass twice normal, and failure to fulfill these energy requirements causes impaired wound healing, organ dysfunction, and susceptibility to infection. adequate assessment and provision of nutritional needs is imperative to care for these patients.
the nutritional intake of the patient should be determined and therapeutic interventions can be instituted as appropriate. physical agents can be used to optimize wound healing or manage certain complications. metabolic disturbances associated with the critical illness or postinjury phase of care can be managed with nutritional therapy.
a simple technique to assess the nutritional status of critically ill patients is the karnofsky performance status (kps) scale. a health professional determines the patient’s physical status using this scale in order to obtain a subjective assessment of the patient’s ability to perform normal activities of daily living. the karnofsky scale is particularly useful for assessing the nutritional status of patients who are unable to complete a nutritional assessment independently. a score of 90-100 is considered a perfect health status, while scores of 60-80 and 50-60 are considered independent and dependent health statuses, respectively.
despite the number of studies on the topic, it is still not clear whether nutritional support can improve survival in patients with severe trauma, specifically after burn injury. the lack of general agreement on an optimal nutritional strategy makes it difficult for providers to deliver safe, effective nutritional support to burn patients. on the other hand, nutritional support can significantly influence the morbidity and the mortality of patients with burn injuries. further research is needed to define the most appropriate nutritional support for burn injury. it is also important to determine the most appropriate and cost-effective nutritional support for burn patients.
elderly patients are at high risk for developing a burn injury. the risk of hospitalization after a burn injury is increased in elderly patients, and they can have complications of nutritional support that may be more severe than in younger patients. burn injuries in the elderly may be more difficult to diagnose and treat because of the physiological changes that occur with aging. multiple organ dysfunction syndrome (mods) and sepsis may be more common in elderly patients with burn injuries. burn injury in the elderly has a significant impact on their health care costs and outcomes. elderly patients who survive a burn injury should have a long-term follow-up and should be monitored for the development of complications such as malignancies. further research is needed to determine the most appropriate and cost-effective nutritional support in the elderly burn patient.
