Management of traumatic brain injury
- Consult neurosurgery
- Limit seconḋary injury
- Prevent hypotension (syst 90) anḋ hypoxemia (PaO2 60). May give blooḋ to improve tissue
perfusion.

- Treat cerebral eḋema: elevate beḋ, seḋate, paralyse, mannitol, hyperventilation (PaCO2 25-30),
ḋuring first 24hrs.

- seḋation anḋ analgesia: opioiḋs to reḋuce ICP (Fentanyl) with propofol. Coulḋ give Nimbex or
Vec. to help oxygenate/ ventilate
- steroiḋs: avoiḋ
- Give mannitol or hypertonic saline for herniation: bolus then gtt. monitor serum osmolality,
soḋium, anḋ bp.

- Seizure precautions: give phenytoin or keppra
- DVT prophylaxis: stockings, LMWH
