Nutrition in head trauma patients
Educational symposia
ESPEN 2011 09 04
To feed or not to feed?– that is
the question
How to feed and not to feed? –
thats another question

Introduction • TBI has special needs: 50 % of the patients do not
tolerate enteral feeding (elevated ICP is associated with low gastric contractibility)
• Metabolite variations with increased energy expenditure, catabolism and glucose intolerance
• Besides adequate O2, CPP, is nutrition playing a role?
• When to start, how much, which route, special nutrients?

the sixties
Nutritional disturbances are not usually considered very important in the postoperative care of patients with head trauma.
In the sixties it was suggested that no efforts is needed to correct the imbalances of fluid, electrolytes and amino acids.

Head trauma historical aspects: the sixties a case at the ICU, S:t Görans hospital,
Stockholm
• 30 year old man, head trauma, smaller fractures, surgical intervention. Treated in ventilator, antibiotic treatment.
• The “nutrition” was two or three liters of glucose 5o mg/ml. He didn´t tolerate any enteral nutrition
• The patient developed a severe catabolism with depletion of the protein stores. He lost around 20% of his body weight. His heart rate began to fall after two weeks.

Head trauma historical aspects: the sixties Arvid Wretlind • “You must understand”, Arvid said, “this
traumatic brain injury can increase the metabolism as much as other traumas and that you have to give him a complete intravenous nutrition”.
• That was the time of hyper alimentation in the US. Arvid calculated that the patient needed around 2500 kcal per day. We gave the patient a complete intravenous nutrition with Intralipid, Glucose 200mg/ml and Aminosol
• The patient recovered- a miracle

Head trauma historical aspects: The seventies
• If any nutrition at all, still
hyper alimentation with hyper- glycemia-problems
• Poor knowledge of the impact of different ventilation methods
• Poor monitoring of the patient

Head trauma historical aspects: The eighties
• Head injury leads to increased energy expenditure (Clifton, Robertson and Grossman in J neurosurgery 1984 a.o)
• In textbooks on intensive care at that time one could still read that you had to wait for up to ten days until you began feeding the (head-) trauma patients.

Head trauma historical aspects: The nineties
”Most investigators agree that aggressive nutritional support, starting within 48 hours of admission to the ICU, maximizes survival”
(Critical Care Practice, The American Society of Critical Care Anesthesiologists, 1992)
The neurosurgical intensive care has achieved major advancements since then including advanced monitoring of ICP, oxygen tension, glucose etc etc.

Biochemical / metabolic processes - Clear association with metabolism and
nutrition
• Ischemia – reperfusion – ROS
• Excitatory amino acids
• Apoptosis
• Mitochondrial dysfunction
• Coagulation disturbances
• Neuroinflammation
• Whole body neuroendocrine stress response

Stress response in head trauma • Metabolic changes in isolated severe head
injuries
– The same pattern as in non-head trauma
• Increases in ”stress hormone”
• Cytokine response
• Increased energy expenditure
• Hyperglycemia, hyperinsulinemia, increased FFA
• Apart from changes in lactate
• Damage in hypothalamic region common in severe head trauma
– Important in metabolic control

Nutritional problems
• Metabolic stress
• GI-problems
• Increased muscular activity
• Increased energy consumption
• Loss of lean body mass
• Confusion

How to assess energy need in head trauma patients
• Assessment of need
– Indirect calorimetry
– Equations
• Harris Benedict
• Swinamer, the Ireton-Jones 1992
• Penn-State equations from 1998 and 2003.
• more validation studies are needed.

Gastric versus transpyloric feeding in severe
traumatic brain injury: a PRT Acosta-Escribano J, ICM, 2010;36;1532
104 patients randomized to TPF or GF groups
Target 25 kcal kg(-1) day(-1) of calculated energy requirements
and a nitrogen intake of 0.2 g N kg(-1) day(-1).
TPF group lower incidence of pneumonia, OR 0.3 (95% CI
0.1-0.7, P = 0.01).
The TPF group received higher amounts of diet compared to
the GF group (92 vs. 84%, P < 0.01) and lesser incidence of
high gastric residuals, OR 0.2 (95% CI 0.04-0.6, P = 0.003)

Nutrition along the way
• Nutritional need?
• To cover the nutritional need?
• Route of nutrition?
• Specific
– composition
– nutrients
• Pharmaconutrients?
• Importance of normoglycemia – at which level?
![Page 63: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/63.jpg)
Rehabilitation
![Page 64: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/64.jpg)
Rehabilitation
• The aim: – To ensure the nutritional status - to support the
rehabilitation process
– To avoid pneumonia
• Sub-acute rehabilitation – Specialized neurorehabilitation in hospital (approx 14 days
after TBI)
• Long-term rehabilitation – Rehabilitation in primary care included specialized
neurorehabilitation (after 3 months in sub-acute rehabilitation)
![Page 65: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/65.jpg)
Sub-acute rehabilitation
• Nutritional Screening (NRS, 2002)
• NGT or PEG
• Screening for dysphagia: – Screening by water-test
– Clinical examination e.g. Facial Oral Tract Therapy (F.O.T.T.®)
– Fiberoptic endoscopy evaluation of swallowing (FEES)
![Page 66: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/66.jpg)
F.O.T.T.® • Developed by Kay Coombes and based on Bobath
concept. A holistic structured assessment and treatment tool
• F.O.T.T covers four areas:
• Swallowing
• Oral hygiene
• Breathing and voice/speech production
• Non-verbal communication (Schow & Jakobsen, Disability and rehabilitation, 2010;32 (17):1447-1460)
![Page 67: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/67.jpg)
Long-term rehabilitation
• Getting back to ”normal”
–Undereating
–Overeating
• Food consistency
![Page 68: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/68.jpg)
Ethical dilemmas
![Page 69: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/69.jpg)
Clinical characteristics for coma, vegetative state and minimal conscious state
• No eye opening either spontaneously or on stimulation
• No sure perception, communication skills or specific motor activity (to follow command)
Coma
• Sleep-awake cycle, arousal often sluggish, barely sustainable but may be normal
• No sure perception, communication skills or specific motor activity (to follow command)
Vegetative State
• Eyes open spontaneously; sleep-awake cycle, arousal levels from dull to normal
• Reproducible but incoherent perception, communication skills or meaningful motor activity, visual "tracking" is often intact
Minimal Conscious State
![Page 70: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/70.jpg)
Vegetative state TBI
• Persisent vegetative state >1 Month
• Permanent vegetative state >1 Year
– Prognosis for PVS is poor
– It is unlikely but not impossible that the patient wakes
(Giacino & Kalmar, Neuropsychological Rehabilitation, 2005)
![Page 71: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/71.jpg)
The patient in vegetative state
• Letting die or assisting death?
• The patient is unable to request this course, unless he/she had already made some advance directive
• The patient is not suffering, nor he is terminally ill – the two reasons usually given for withdrawing or withholding treatment
(Jennet, Current Anaesthesia and Critical care, 1999)
![Page 72: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/72.jpg)
Potential outcomes continuing nutritional support
• The person may emerge from the vegetative state • The person may not emerge • If the person does emerge, he/she may be left with
significant disabilities • If the person does not emerge, he/she can relate to no-
one • If the person does not emerge, other relationsships
within the family group may be threatened by the emotional or finacial strain of the situation
(Malec, Brain Injury, 1996)
![Page 73: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/73.jpg)
The potential outcomes and risks of discontinuing nutritional support may
include
• The person will die
• Guilt in reaction to the person´s death will threaten relationships among significant others
![Page 74: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/74.jpg)
Challenges
![Page 75: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/75.jpg)
Challenges • The importance of diagnostics
• Proffesionality among staff
• Communication with families
• Treat the patient as if he/she was counscious
• Families may change their perception of quality of life for the person in the vegetative stage prior to injury to after injury
(Fins, Disorders of consciosness, 2009; 1157:131-147)

Concluding remarks
• Early
–Metabolic and nutritional considerations
• Later
–A prerequisite for rehabilitation
![Page 77: Folke Hammarqvist - European Society for Clinical … Hammarqvist ESPEN Congress Gothenburg 2011 Traumatic brain injury – case discussion of nutritional, caring and ethical aspects](https://reader031.fdocuments.us/reader031/viewer/2022030416/5aa2a8607f8b9a84398d50b6/html5/thumbnails/77.jpg)
Concluding remarks
• Nutritional treatment important
• Measure if possible the patients need
• Early enteral nutrition
– But intolerance common
– Partial PN
• Consider PEG in selected cases
• An important multidisciplinary teamwork
