Terapia nutricional no traumatismo cranioencefálico grave
REVIEW ARTICLE
INTRODUCTIONHead trauma (HT) continues to be a highly lethal condition, with an overall mortality of 20% to 50% in the United States of America (USA).(1)HT causes 52,000 deaths annually in the USA, with 85% of these deaths occurring within the first two weeks after the trauma.(2) Brazilian statistics on HT are sparse and are only available for specific regions. In São Paulo, the 1997 HT admission rate was 0.36 per 1,000 inhabitants, with an estimated mortality rate of 26 to 39 per 100,000 inhabitants. Currently, strategies for maintaining brain perfusion and preventing hypoxemia, hypotension and intracranial hypertension have reduced the risk of death and improved severe HT outcomes. (4) In spite of the limited data on the relevance of nutrition therapy for HT patients, two systematic Cochrane Collaboration reviews have suggested
ABSTRACTThis article reviews the literature, organizes the major findings, and generates the best evidence-based recommendations on nutrition therapy for head trauma patients. Despite recent advances in head trauma diagnosis and therapy, the mortality associated with this condition remains high. Few therapeutic interventions have been proven to effectively improve this condition. Head trauma causes multiple metabolic and electrolytic disorders; it is characterized by a hypermetabolic state that is associated with intensive catabolism, leading to specific nutritional needs.The current literature lacks specific guidelines for nutrition therapy in severe head trauma patients, although a substantial amount of data has been reported and relevant issues are currently being studied; these data may allow better nutrition therapy guidelines for these patients. In addition to a welltrained multi-disciplinary team, the following recommendations appear to improve outcomes: introducing nutrition therapy early; preferred enteral administration; appropriate energy intake; formulations that are tailored to specific patients, including appropriate nutrients; and strict electrolytic and metabolic monitoring. Understanding the pathophysiology and the consequences of therapy is fundamental.
