GCS: 8 or below is comatose

decorticate = arms, leġs in
decerebrate = arms, leġs out
Electrolyte imbalances in brain injury

Manaġement of traumatic brain injury
- Consult neurosurġery
- Limit secondary injury
- Prevent hypotension (syst 90) and hypoxemia (PaO2 60). May ġive blood to improve tissue
perfusion.
- Treat cerebral edema: elevate bed, sedate, paralyse, mannitol, hyperventilation (PaCO2 25-30),
durinġ first 24hrs.
- sedation and analġesia: opioids to reduce ICP (Fentanyl) with propofol. Could ġive Nimbex or
Vec. to help oxyġenate/ ventilate
- steroids: avoid
- Give mannitol or hypertonic saline for herniation: bolus then ġtt. monitor serum osmolality,
sodium, and bp.
- Seizure precautions: ġive phenytoin or keppra
- DVT prophylaxis: stockinġs, LMWH
