IOM Report: Nutrition and Traumatic Brain Injury (TBI)

The Institute of Medicine (IOM) released a report last week summarizing a project that examined the impact of nutrition on head injury. The Department of Defense requested this review because of the significant morbidity and mortality incurred by our armed forces caused by TBI.

The IOM convened a panel of experts that reviewed the available data. As with most such panels, there is a recommendation to engage in additional research. They went a step further, though, and recommended several specific avenues of research, including:

  • Determine optimum levels of blood glucose
  • Study the benefits of insulin therapy
  • Determine the optimal goals for nutrition
  • Look at the effects of supplements and various diets, CDP-choline, creatine, n-3 fatty acids, fish oil and zinc supplements

The most pressing recommendation they made was a call to standardize the feeding regimen for severe TBI patients very early after injury. Specifically, they recommend that nutritional support be started within 24 hours of injury, consisting of 50-100% of the total energy expenditure with 1 to 1.5 g protein per kg body weight. This should be continued for the first 2 weeks after injury. It appears that this intervention limits the intensity of the inflammatory response after TBI and improves outcomes.
