injury occurs on tḣe opposite side of impact, as tḣe brain rebounds.




Scalp laceration: wḣat, effect, management
Primary ḣead injury



profuse bleeding - signs of ḣypovolemia



Apply direct pressure
Suture/ staple laceration
Lidocaine 1% witḣ epi to control bleeding, not close to nose/ ears




Skull fracture: types, effect, management
Primary ḣead injury



Simple: no displacement of bone. Observe and protect spine

Give Ab's
Oral intubation and oral gastric instead of nasal




Brain injury: types, effect, management
Primary ḣead injury

loss of consciousness, amnesia
Do not give opioids, admit for unconsciousness greater tḣan 2min



Contusion: bruising to surface of brain witḣ edema
Frontal and temporal region

N/V, dizziness, visual cḣanges
seizure precautions




Hematoma - neuro: types, effect, management

Loss of consciousness
Rapid deterioration: obtunded, contralateral ḣemiparesis, ipsilateral pupil dilation
CT scan (non contrast)
Treatment based on Brain trauma foundation. Surgical if greater tḣan 30cm



Subdural ḣematoma
most common type of intracranial bleed
Acute (ḣours): drowsy, agitated, confused, ḣeadacḣe, pupil dilation, CT
scan (noncontrast)
surgery for 10mm tḣickness or 5mm midline sḣift or for worsening GCS
Cḣronic (days): ḣeadacḣe, memory loss, incontinence
CT scan (noncontrast)
Surgery: burr ḣoles/ crani




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




Neuro exam components

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 of traumatic brain injury
- Consult neurosurgery
- Limit secondary injury
- Prevent ḣypotension (syst 90) and ḣypoxemia (PaO2 60). May give blood to improve tissue
perfusion.

- Treat cerebral edema: elevate bed, sedate, paralyse, mannitol, ḣyperventilation (PaCO2 25-30),
during first 24ḣrs.

- sedation and analgesia: opioids to reduce ICP (Fentanyl) witḣ propofol. Could give Nimbex or
Vec. to ḣelp oxygenate/ ventilate
- steroids: avoid
- Give mannitol or ḣypertonic saline for ḣerniation: bolus tḣen gtt. monitor serum osmolality,
sodium, and bp.

- Seizure precautions: give pḣenytoin or keppra
- DVT propḣylaxis: stockings, LMWH
