Mechanisms of injury

Mechanisms of Injury

What now

What now?



  • Aairway with cervical spine control

  • Bbreathing

  • Ccirculation

Traumatic brain injury

Traumatic Brain Injury

Immediate impact injury

  • Contusions and lacerations

  • Diffuse damage to white matter

  • Other types of diffuse brain injury

    Primary complications

  • Intracranial haemorrhage

  • Brain swelling

    Secondary complications

  • Brain damage secondary to raised ICP

  • Hypoxic brain damage

  • Infection

Head injury


  • Prevent secondary brain injury

  • Rapid transfer to hospital

Brain herniation

Brain Herniation

Uncal herniation

Uncal Herniation

Midbrain infraction

Midbrain Infraction

Cerebral physiology

Cerebral Physiology

  • Intracranial pressure (ICP) 0-10 mmHg

  • Cerebral perfusion pressure (CPP) >60 mmHg

  • Obligative aerobic glycolysis

  • Cerebral blood flow (CBF) maitained by autoregulation

Severe head injury

Severe Head Injury

  • Raised ICP

  • Reduced CPP

  • Loss of autoregulation

  • Neuroexcitotoxicity

Raised icp

Raised ICP

  • Seizures

  • Brain swelling

  • Vasogenic oedema

  • Intracranial haematoma

  • Hypercarbia

  • Hypoxia

Neurological assessment

Neurological Assessment

  • Level of consciousness (GCS)

  • Pupillary reaction to light

  • Limb movements

  • History

Complicating factors

Complicating Factors

  • Alcohol

  • Drugs

  • Epilepsy

  • Stroke

  • Cervical spine injury

The glasgow coma scale and score

Eye (1-4)

open spontaneously

open to speech

open to pain

no opening

Motor (1-6)

obeys commands

localises to pain

normal flexion

abnormal flexion


no movement

Verbal (1-5)



inappropriate words

incomprehensible sounds


GCS 3-15

Best score using upper limbs

Special cases


periorbital oedema

endotracheal tube/tracheostomy

The Glasgow Coma Scale and Score
