2. Introduction
 Nearly 1.4 million individuals per year suffer from
TBI, leaving many of the survivors with significant
deficits
 Moderate to severe traumatic brain injury (TBI)
results in a mortality rate of approximately 33%
 Early and adequate nutrition support is challenging
to provide in the TBI population, but it may improve
the overall clinical course in TBI patients as well

4. Nutrition Access
 Enteral > Parenteral
 Within 72 hours, in selected cases, parenteral until
enteral access can be obtained
 When TBI patients require long-term EN, a more
secured enteral access device, gastrostomy, is
optimal and preferred by most long-term care
facilities

5. Timing of Nutrition
 Early EN (within 48 hours) is clearly an important
goal for the initial nutrition support plan for a TBI
patient.
 Most TBI patients tolerate receiving at least 50% of
their caloric needs by injury day 2
 The Brain Trauma Foundation promotes a level II
recommendation that TBI patients attain full caloric
replacement by day 7 after injury

6. Enteral Nutrition in TBI
 Forestalls the breakdown of protein and fat stores
 Blunts the innate inflammatory response
 Promotes immune competence
 Decreases intensive care unit (ICU) infections
 Limits the risk of bacterial translocation
 Improve neurologic outcome at 3 months

evidence. J Am Diet Assoc. 2007;107:1552-1561

8. Nutrition Assessment: Protein
 The hypercatabolism evident in TBI patients stimulated
by inflammatory mediators and catecholamines often
results in excessive protein breakdown
 Protein catabolism appears to peak 8–14 days after
injury and appears to be related to the severity of injury
 Current recommendations suggest protein provision
ranging between 1.5 and 2 g/kg/day for acute TBI
patients to account for the excess catabolism

9. Nutrition Assessment:
Fluids and Electrolytes
 Crystalloids > Colloids
 Intravenous solutions containing dextrose should be
avoided in the acute phases of TBI

12. Facilitating Enteral Nutrition Tolerance
 30-45 degress head elevation
 Nasojejunal/duodenal feeding tube
 Increase rate gradually
 Continuous infusion
 Concentrated formula
 Promotility agents such as metoclopramide or
erythromycin may also be considered
Cook, A. M., Peppard, A., & Magnuson, B. (2008). Nutrition considerations in traumatic brain injury. Nutrition in clinical practice, 23(6), 608-620

13. Challenges
 Continued increase in metabolism and protein loss
due to persistent inflammatory response and
prolonged immobility due to injury.
 Spasticity, decorticate or decerebrate posturing, and
periodic sympathetic discharges (“storming”) are all
associated with increased caloric needs
 Inadequate nutrition support for TBI patients, even
well past the initial injury, may result in malnutrition
and muscle wasting and cachexia
Cook, A. M., Peppard, A., & Magnuson, B. (2008). Nutrition considerations in traumatic brain injury. Nutrition in clinical practice, 23(6), 608-620

14. Challenges
 Many TBI patients are not able to take in an
adequate volume of fluids orally to meet their daily
fluid needs due to impaired swallowing or altered
consciousness
 As the TBI patient transitions to a less intensive care
setting, the calorically dense formula used in the ICU
should be gradually converted to a more high-
volume, isotonic enteral formula to provide a higher
percentage of free water per volume
Cook, A. M., Peppard, A., & Magnuson, B. (2008). Nutrition considerations in traumatic brain injury. Nutrition in clinical practice, 23(6), 608-620

15. Oral Diets
 The incidence of dysphagia after a TBI is reported to be
as high as 61%
 Most TBI patients regain their independence in oral
feeding within the first 6 months after injury
 Oral feedings increase the quality of a patient’s life
 Initial swallowing assessment begin within 2-4 weeks of
injury
 The patient’s swallowing ability should continue to be
assessed and treated until the patient is able to tolerate
the least restricted diet or functional recovery plateau
 Speech pathologist
Cook, A. M., Peppard, A., & Magnuson, B. (2008). Nutrition considerations in traumatic brain injury. Nutrition in clinical practice, 23(6), 608-620

16. Pediatric Consideration
 More quality evidence is needed in many areas of
pediatric TBI to guide decision-making.
 At this point, it appears prudent to initiate nutrition
(preferably EN) as soon as is feasible and to target up
to 160% of the calculated BEE until indirect
calorimetry can be performed.

17. Summary
 TBI care: multiaspects  including nutrition
 Enteral nutrition: optimal route
 Provision of adequate calories and protein is critical
for recovery
 ASPEN: Early EN initiated within 24–72 hours after
injury
 The Brain Trauma Foundation recommends the TBI
patient receive their goal nutrition support by at
least day 7 of injury
