5. In Bangladesh??
TBI due to Fall and Death: 36.3
per 1000 and 5 per 100,000
population, respectively

6. TBI Definition
• “Brain damage resulting from external
forces, as a consequence of direct impact,
rapid acceleration or deceleration, a
penetrating object (e.g., gunshot) or blast
waves from an explosion. The nature,
intensity, direction and duration of these
forces determine the pattern and extent of
damage.”

7. Scope of guideline
• The guidelines address treatment interventions, monitoring,
and treatment thresholds that are specific to TBI or that
address a risk that is greater in patients with TBI.
• The guidelines are not intended to cover all topics relevant to the
care of patients with severe TBI.
• Topics related to general good care for all patients, or all trauma
patients, are not included.
• These recommendations are intended to provide the foundation
on which protocols can be developed that are appropriate to
different treatment environments.

8. Living Guideline
• This Fourth Edition of the Guidelines which was
published in September, 2016 is transitional.
• They do not intend to produce a Fifth Edition.
Rather, moving to a model of continuous
monitoring of the literature, rapid updates to the
evidence review, and revisions to the
recommendations as the evidence warrants.
• So they call this the :
Living Guidelines model

9. Methods
• The development of guidelines encompasses 2
major activities:
• First: A systematic review and synthesis of
evidence;
• Second: The derivation of recommendations.
• There are 189 publications used for evidence—
• 5 Class 1
• 46 Class 2
• 136 Class 3 studies
• 2 meta-analyses.

10. Level of Recommendation
• Recommendations in this edition are designated as Level I, Level
II A, Level II B, or Level III. The Level of Recommendation is
determined by the assessment of the quality of the body of
evidence, rather than the class of the included studies.
• • Level I : Standards : Recommendations were based on a high-
quality body of evidence.
• • Level II A : Guidelines : Recommendations were based on a
moderate-quality body of evidence.
• • Level II B and III : Options : Recommendations were based on a
low-quality body of evidence.

12. Treatment Recommendations:
• 1. Decompressive craniectomy: Level IIA
• • Bifrontal DC is not recommended to improve outcomes as measured by the
GOS-E score at 6mo post-injury in severe TBI patients with diffuse injury
(without mass lesions), and with ICP elevation to values ≥ 20mmHg for more
than 15 min within a 1-h period that are refractory to first-tier therapies.
However, this procedure has been demonstrated to reduce ICP and to
minimize days in the ICU.
• • A large frontotemporoparietal DC (not less than 12 x 15 cm
or 15 cm diameter) is recommended over a small
frontotemporoparietal DC for reduced mortality and improved
neurologic outcomes in patients with severe TBI.

13. • Prophylactic hypothermia: Level IIB
• • Early (within 2.5 h), short-term (48 h post-injury),
prophylactic hypothermia is not
recommended to improve outcomes in
patients with diffuse injury.
Treatment Recommendations:

14. • Hyperosmolar therapy: Level I, II, and III
• • Although hyperosmolar therapy may lower intracranial
pressure, there was insufficient evidence about effects on clinical
outcomes to support a specific recommendation, or to support
use of any specific hyperosmolar agent, for patients with severe
traumatic brain injury.
• Mannitol is effective for control of raised ICP at doses of
0.25 to 1 g/kg body weight. Arterial hypotension (systolic blood
pressure , 90 mm Hg) should be avoided.
Treatment Recommendations:
Tips on Mannitol:
1. The indications for mannitol are as a one-
time dose to lower ICP while obtaining
further diagnostic studies or while waiting
for definitive treatment.
2. Mannitol or hypertonic saline can be used
as a trauma resuscitation fluid for
permissive hypotenstion but prevent
hypotension if systolic BP <90 mm of Hg.
3. Serum osmolality should not generally be
allowed to go much above 320 mOsm/L, if
possible, to avoid systemic acidosis and
renal failure.

15. • Cerebrospinal fluid drainage: Level III
• • An EVD system zeroed at the midbrain with
continuous drainage of CSF may be considered to
lower ICP burden more effectively than intermittent
use.
• • Use of CSF drainage to lower ICP in patients with
an initial GCS 6 during the first 12 h after injury may
be considered.
Treatment Recommendations:

16. • Ventilation therapies: Level IIB
• • Prolonged prophylactic hyperventilation with PaCO2 of
< 25 mm Hg is not recommended.
• Recommendations from the prior (Third) Edition not supported
by evidence meeting current standards. Hyperventilation is
recommended as a temporizing measure for the reduction of
elevated ICP. Hyperventilation should be avoided during
the first 24 h after injury when CBF often is reduced
critically.
• If hyperventilation is used, SjO2 or BtpO2 measurements are
recommended to monitor oxygen delivery.
Treatment Recommendations:

17. • Anesthetics, analgesics, and sedatives: Level IIB
• • Administration of barbiturates to induce burst suppression measured by EEG
as prophylaxis against the development of intracranial hypertension is not
recommended.
• • High-dose barbiturate administration is recommended to
control elevated ICP refractory to maximum standard medical and surgical
treatment. Hemodynamic stability is essential before and during barbiturate
therapy.
• • Although Propofol is recommended for the control of ICP, it is not
recommended for improvement in mortality or 6-month outcomes. Caution is
required as high-dose propofol can produce significant morbidity.
• Multimodal analgesia and Central acting drugs like
acetamenophen, Tramadol Hcl, Fentanyl can be used for
analgesia.
Treatment Recommendations:

18. • Steroids: Level I
• The use of steroids is not recommended for
improving outcome or reducing ICP. In
patients with severe TBI, highdose
methylprednisolone was associated with
increased mortality and is :
Treatment Recommendations:

19. Contraindicated

20. • Nutrition: Level IIA
• Goal: Caloric replacement begins around 72 hours after injury.
• Three ways to initiate early feeding: 1. gastric, 2. Jejunal,
3. Parenteral. It is important to maintain normoglycemia in head
injury patients as hyperglycemia has been associated with worse
outcomes.
• Feeding patients to attain basal caloric replacement at least by
the fifth day and at most by the seventh day post-injury is
recommended to decrease mortality.
Treatment Recommendations:

21. • The amount of nutrition in the first 5 days was related to death;
every 10-kcal/kg decrease in caloric intake was associated with a
30% to 40% increase in mortality rates adjusted for injury
severity.
• Caloric expenditure after TBI averages 140% of normal resting
energy expenditure (REE), based on age, gender, and body size.
• 70-kg, 25-year-old man, normal REE is 1700 kcal/day. The projected caloric
expenditure is 2400 kcal/day. In patients who are paralyzed or in a barbiturate
coma, caloric expenditure is 100% to 120% of normal resting levels.
• Enteral feedings should begin as soon after injury as
possible but certainly within 72 hours. The goal should
be to gradually increase feedings and be at full caloric
replacement by the end of the first week postinjury.

22. Level II B
• Transgastric jejunal feeding is
recommended to reduce the incidence of
ventilator-associated pneumonia.

23. • Infection prophylaxis: Level IIA
• Early tracheostomy is recommended to reduce mechanical
ventilation days when the overall benefit is thought to outweigh
the complications associated with such a procedure. However,
there is no evidence that early tracheostomy reduces mortality or
the rate of nosocomial pneumonia.
• The use of PI oral care is not recommended to reduce ventilator-
associated pneumonia and may cause an increased risk of acute
respiratory distress syndrome.
Treatment Recommendations:

24. • Level III
• Antimicrobial-impregnated catheters may be considered to
prevent catheter-related infections during external ventricular
drainage.
• Role of Prophylactic Antibiotics: One Class 3 study addressed
this topic and found that antibiotics did not reduce bacterial
colonization and were associated with more severe infections.
Treatment Recommendations:

26. • Deep vein thrombosis Prophylaxis: Level III
• LMWH or low-dose unfractioned heparin may be used in
combination with mechanical prophylaxis. However, there is an
increased risk for expansion of intracranial hemorrhage.
• In addition to compression stockings, pharmacologic prophylaxis
may be considered if the brain injury is stable and the benefit is
considered to outweigh the risk of increased intracranial
hemorrhage.
• There is insufficient evidence to support recommendations
regarding the preferred agent, dose, or timing of pharmacologic
prophylaxis for deep vein thrombosis.
Treatment Recommendations:

27. • Prophylaxis options can be considered in two
categories:
• 1. Mechanical:
• a. Graduated compression stockings,
• b. Intermittent pneumatic compression stockings
• 2. Pharmacological:
• a. low-dose heparin
• b. low molecular weight heparin
Treatment Recommendations:

28. • Seizure prophylaxis: Level IIA
• Prophylactic use of phenytoin or valproate is not recommended
for preventing late PTS.
• Phenytoin is recommended to decrease the incidence
of early PTS (within 7 d of injury), when the overall benefit is
thought to outweigh the complications associated with such
treatment. However, early PTS have not been associated with
worse outcomes.
• At the present time there is insufficient evidence to recommend
levetiracetam compared with phenytoin regarding efficacy in
preventing early post-traumatic seizures and toxicity.
Treatment Recommendations:

29. Monitoring Recommendations
• Intracranial pressure monitoring :Level IIB
• Management of severe TBI patients using information from ICP monitoring is
recommended to reduce in hospital and 2-week post-injury mortality.
• ICP should be monitored in all salvageable patients with a TBI
(GCS 3-8 after resuscitation) and an abnormal CT scan. An
abnormal CT scan of the head is one that reveals hematomas,
contusions, swelling, herniation, or compressed basal cisterns.
• ICP monitoring is indicated in patients with severe TBI with a
normal CT scan if ≥2 of the following features are noted at
admission:
• Age : 40 years
• Unilateral or Bilateral motor posturing, or SBP ,90 mm Hg.

30. Monitoring Recommendations
• Cerebral perfusion pressure monitoring:
Level IIB
• Management of severe TBI patients using
guidelines-based recommendations for CPP
monitoring is recommended to decrease 2-wk
mortality.

31. Advanced cerebral monitoring: Level III
• Jugular bulb monitoring of AVDO2, as a
source of information for management
decisions, may be considered to reduce
mortality and improve outcomes at 3 and 6
mo post-injury.
Monitoring Recommendations

32. Threshold Recomnendations
• Blood pressure thresholds : Level III
• Maintaining SBP at
≥100 mm Hg for patients 50 to 69 years old
≥ 110 mm Hg or above for patients 15 to 49 or 70 years old
Considered to decrease mortality and improve
outcomes.

33. Threshold Recomnendations
• Intracranial pressure thresholds : Level IIB
• Treating ICP > 22 mm Hg is recommended
because values above this level are associated
with increased mortality.

34. Threshold Recomnendations
• Cerebral perfusion pressure thresholds
Level IIB
• The recommended target CPP value for survival and favorable
outcomes is between 60 and 70 mm Hg.
Level III
• Avoiding aggressive attempts to maintain CPP ≥70 mm Hg with
fluids and pressors may be considered because of the risk of adult
respiratory failure.

35. Threshold Recomnendations
• Advanced cerebral monitoring thresholds
Level III
• Jugular venous saturation of > 50% may be a
threshold to avoid in order to reduce mortality and
improve outcomes.

36. Conclusion
• Often, the available evidence is not sufficient to generate
guidelines addressing the most critical questions faced by
clinicians and patients. Although there have been some major
developments in severe TBI management, for other topics in
this edition it was not possible to make new evidence-based
recommendations.
• This Living Guideline should be followed through out the
world till new recommendations are added for the beneficial of
patients suffering from severe TBI.
