Management of Contrecoup Cerebral Injury

Immediate Pre-Hospital and Emergency Management

The American College of Surgeons recommends maintaining systolic blood pressure >110 mmHg from the moment of first contact to prevent secondary brain injury 1, 2, 4
Even a single episode of hypotension (SBP <90 mmHg) markedly worsens neurological outcome, and mortality increases significantly when SBP drops below 110 mmHg, according to the Brain Trauma Foundation 1, 2
The use of vasopressors (phenylephrine or norepinephrine) is recommended immediately for hypotension rather than waiting for fluid resuscitation or sedation adjustment, as these have delayed hemodynamic effects, as stated by the American Society of Anesthesiologists 1, 5
Avoiding hypotensive sedative agents and using continuous infusions rather than boluses is advised by the Society of Critical Care Medicine 1, 5

The American College of Radiology recommends obtaining non-contrast brain and cervical spine CT without delay to guide neurosurgical procedures and monitoring techniques 2, 4, 3
The use of inframillimetric sections reconstructed with thickness >1mm, visualized with double fenestration (central nervous system and bone windows), is suggested by the Neurocritical Care Society 2, 4

The Congress of Neurological Surgeons recommends performing surgical evacuation for symptomatic extradural hematoma (any location), acute subdural hematoma with thickness >5mm and midline shift >5mm, acute hydrocephalus requiring drainage, open displaced skull fracture, and closed displaced skull fracture with brain compression (thickness >5mm, midline shift >5mm) 5, 3

The Neurocritical Care Society suggests implementing intracranial pressure monitoring in severe TBI to guide ICP-directed therapy and maintaining adequate cerebral perfusion pressure 3
The Society of Critical Care Medicine recommends maintaining normothermia using targeted temperature control, as hyperthermia increases complications and unfavorable outcomes including death 3

Allowing even brief episodes of hypotension while waiting for "adequate resuscitation" before starting vasopressors is a common error, according to the American Heart Association 1, 2
Using bolus sedation rather than continuous infusions, causing hemodynamic instability, is advised against by the American Society of Anesthesiologists 1, 5
Delaying transfer to a specialized center for "stabilization" at a non-neurosurgical facility is discouraged by the Brain Trauma Foundation 1, 2
