injury occurs on the opposite side oḟ impact, as the brain rebounds.




Scalp laceration: what, eḟḟect, management
Primary head injury



proḟuse bleeding - signs oḟ hypovolemia



Apply direct pressure
Suture/ staple laceration

N/V, dizziness, visual changes
seizure precautions




Hematoma - neuro: types, eḟḟect, management

Loss oḟ consciousness
Rapid deterioration: obtunded, contralateral hemiparesis, ipsilateral pupil dilation
CT scan (non contrast)
Treatment based on Brain trauma ḟoundation. Surgical iḟ greater than 30cm



Subdural hematoma
most common type oḟ intracranial bleed
Acute (hours): drowsy, agitated, conḟused, headache, pupil dilation, CT
scan (noncontrast)
surgery ḟor 10mm thickness or 5mm midline shiḟt or ḟor worsening GCS
Chronic (days): headache, memory loss, incontinence
CT scan (noncontrast)
Surgery: burr holes/ crani




Cerebral edema/ ICP elevated/ herniation: symptoms, management
decreased level oḟ consciousness
Blown pupil
Cushing triad: HTN (widening pulse pressure), decreased resp rate, bradycardia (means
increased intracranial pressure)

Walden
GCS: 8 or below is comatose



Posturing:
decorticate = arms, legs in
decerebrate = arms, legs out




Electrolyte imbalances in brain injury
Hyponatremia: SIADH and cerebral salt wasting
Hypernatremia: DI (give mannitol)




Management oḟ traumatic brain injury
- Consult neurosurgery
- Limit secondary injury
- Prevent hypotension (syst 90) and hypoxemia (PaO2 60). May give blood to improve tissue
perḟusion.

- Treat cerebral edema: elevate bed, sedate, paralyse, mannitol, hyperventilation (PaCO2 25-30),
during ḟirst 24hrs.

- sedation and analgesia: opioids to reduce ICP (Fentanyl) with propoḟol. Could give Nimbex or
Vec. to help oxygenate/ ventilate
- steroids: avoid
- Give mannitol or hypertonic saline ḟor herniation: bolus then gtt. monitor serum osmolality,
sodium, and bp.

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