AbstractUntil some years ago, patients suffering from head injury were poorly fed and nutrition was not a primary concern in the medical treatment of these patients. To date, six studies on head-injury patients have examined the effect of nutritional support on their outcome. All showed that lack of adequate nutrition contributed to increased mortality and morbidity. Head-injured patients on conventional enteral nutrition receive significantly less calories and proteins, resulting in an increased morbidity and mortality rate. Most of the severely head injured patients receiving enteral nutrition do not tolerate enteral feedings because of abnormal gastric emptying. The mechanisms of altered gastric function remain obscure. Increased intracranial pressure, cytokines, corticotropin-releasing factor, opiates, and other agents may all play a role. Impaired gastric motility has led to increasing use of small bowel feeding in head-injured patients. Jejunal feeding enables a higher caloric input and a better nitrogen balance. Moreover, it enables early enteral administration of nutrients in a safe and efficient way. Early administration of nutrients may be extremely important as it seems to decrease the hypermetabolic response to traumatic injury. Therefore, early jejunal enteral feeding may become an important cornerstone in the medical management of head-injured patients.
