GUIDELINES FOR THE MANAGEMENT OF PEDIATRIC TRAUMATIC
BRAIN INJURY
These guidelines are to be considered in patients 21 years of age or below with
traumatic brain injury. While these are only guidelines, they are based on
recommendations published in Pediatric Critical Care Medicine February 16, 2012

INITIAL ER MANAGEMENT
1. Upon arrival to the ER, an assessment will be made by the ER staff concerning the
patients’ respiratory, hemodynamic, and neurologic status. Patients with poor gas
exchange and/or hemodynamic instability will be first stabilized prior to any
radiographic studies or neurosurgical interventions.
2. If a patient has a GCS < or = to 8, endotracheal intubation using head injury
precautions should be performed. Intubation should also be considered in cases of
hemodynamic instability or if a patient needs sedation for transport. When stable, the
patient should then have the appropriate studies performed. Appropriate sedation and
analgesia should be used while the patient is intubated and/or transported.
GOALS FOR GAS EXCHANGE
3. The goals for gas exchange should be normoxia (SaO2 > 90%, PaO2 > 60) and
normocarbia (pCO2 ~ 40). Hyperventilation to a pCO2 ~ 30-35 should only used if
there are clinical signs of intracranial hypertension as manifest by signs of herniation
(pupillary dilatation, motor posturing, deteriorating mental status, etc) for the first 24
hours after injury.
HEMODYNAMIC GOALS
4. The goal for blood pressures should be > than 5th % for age, until further physiologic
parameters (i.e. CPP) can be determined. Arterial catheters and central venous
catheters should be considered in patients with respiratory, hemodynamic, or
neurologic instability.
SURGICAL INTERVENTIONS
5. Patients with mild (GCS 14-15) and moderate head injuries (GCS 9-13) may have
their neurologic status monitored clinically, without ICP monitoring devices (this will
be at the discretion of the Attending Neurosurgeon).
6. In cases of severe head injury an ICP monitor should be placed. Severe head injury is
defined as:
(a). GCS < or = 8 and an abnormal head CT scan or
(b). GCS < or = 8 and motor posturing and systemic hypotension or
(c). Absence of purposeful movements and an abnormal head CT scan
7. Those patients with moderate TBI that will undergo anesthesia for the management
of extracranial injuries should also have ICP monitoring.
8. The type of monitor used (Camino vs. EVD vs. Dual Bolt/EVD) will be determined
by the Attending Neurosurgeon. Consideration should be made about the placement
of a lumbar drain.
9. If upon placement of an ICP monitor, ICPs are found to be significantly elevated,
despite sedation, CSF drainage, and osmotherapy, decompressive craniectomy should
be strongly considered at this point.
PICU MANAGEMENT OF HIGH ICP/LOW CPP: FIRST TIER THEAPIES
10. Appropriate sedation and analgesia regimens for patients with secured airways will be
determined by the PICU Attending, once the patient arrives in the PICU. Intravenous
lidocaine may be given prior to noxious stimuli (ex. endotracheal tube suctioning).
11. While in the PICU, the patient’s head will be elevated to 30o and in midline. The
patient’s temperature will be aggressively controlled with antipyretics and will be
held less than 38.5o C. Seizure prophylaxis will be administered. All patients will be
given NS at a maintenance rate for the first 24-48 hours. Glucose levels will be
followed and will be maintained between 80-120 when possible.
12. Acute rises in ICP (>20) or decreased CPP (> 70 in adults, > 50 in children between 8
and 16 years of age, and > 40 in children less than 8 years of age) will be managed
with sedation and/or mannitol or 3% saline. Mannitol may only be used for a serum
osmolarity < or = 320. When using 3% saline, a serum osmolarity of 360 may be
used as the cutoff. Mild hyperventilation (Pco2 = 30-35) may be used for acute rises
in ICP while the osmotic agent is being obtained. EtCO2 should be used to titrate the
degree of hyperventilation.
13. If the patient’s ICP remains stable but elevated, the PICU attending will then consider
the use of vasoactive drugs to improve CPP.
14. Should the ICP remain elevated (>20) despite medical interventions including TWO
doses of mannitol within 12 hours at a minimum dose of 0.25 g/kg, surgical
management should progress to the insertion of a ventricular drain.
SECOND TIER THERAPIES: SURGICAL MANAGEMENT
15. If medical management of ICP is unsuccessful, or if the need for osmotherapy is more
frequent than every 4 hours, and no drain has been placed to this point, than a
ventricular drain should be placed. The patient will then be placed on prophylactic
antibiotics per the Neurosurgery EVD protocol.
SECOND TIER THERAPIES: MEDICAL MANAGEMENT
16. If the ICP continues to be > 20, despite sedation, osmotherapy, and ventricular
drainage, and if the time since injury is > 24 hours, the patient can then be
hyperventilated to a pCO2 ~ 35. End-tidal CO2 may be used to titrate this therapy
17. If the ICP continues to be > 20, despite sedation, osmotherapy, mild hyperventilation,
and ventricular drainage, the patient will then be placed in a pentobarbital coma with
continuous EEG monitoring until burst suppression is achieved. Burst suppression
will be defined as the presence of generalized bursts of sharp and slow waves
followed by generalized amplitude suppression for 8-12 seconds. Other sedating and
analgesic agents should then be discontinued.
TERTIARY TIER THERAPIES
18. If the ICP continues to be elevated, the Attending Neurosurgeon should then consider
the use of decompressive craniectomy, if not already done.
19. If ICP remains persistently high (>20), the PICU Attending should consider 3% saline
infusion.
CRITICAL PATHWAY FOR THE MANAGEMENT OF PEDIATRIC TBI
Cardiopulmonary Resuscitation: See Physiologic Parameters Below*
Intubation using Head Injury Precautions
Appropriate Sedation/Analgesia for Radiographic Studies
ICP monitor and/or drain and other neurosurgical intervention for intracranial bleeding.
This should include consideration of the placement of a lumbar drain as well as
decompressive craniectomy if ICPs are significantly elevated despite sedation/CSF
drainage/osmotherapy after insertion of a monitor in the OR
Sedation/Analgesia, Osmotherapy, Vasoactive Drugs for High ICP or Low CPP *
Consideration of 3% Saline Infusion
Ventricular Drain (if not done previously) if Medical Therapy Unsuccessful
Recommended for continued ICP’s (>20) despite two mannitol doses and continuous
sedation.

Pentobarbital Coma for Unrelenting High ICP or Low CPP *
Consideration of Decompressive Craniectomy (if not done previously)
