    3. To pain or pressure: 2
    4. No Response: 1
  2. Best Verbal Response
    1. Oriented (Infant coos or babbles): 5
    2. Confused (Infant irritable cries): 4
    3. Inappropriate words (Infant Cries to pain): 3
    4. Incomprehensible sounds (Infant Moans to pain): 2

    2. Localizes (infant withdraws to touch): 5
    3. Withdraws to pain: 4
    4. Abnormal Flexion (Decorticate Posturing): 3
    5. Abnormal Extension (Decerebrate Posturing): 2

  • Interpretation
  1. Total: 3-15
  2. Mild Head Injury: 13-15 (at two hours post-injury)
  3. Moderate Head Injury: 9-12 (at two hours post-injury)
  4. Severe Head Injury (Coma): <= 8 (at two hours post-injury)
    1. Confers Significant Mortality Risk
  5. Modifiers
    1. 2T-8
      1. 2T refers to the verbal score uninterpretable due to Endotracheal Intubation
      2. Only motor (1-6) and eye opening (1-4) are calculated (maximum 2T-10)
        1. In this case (2T-8), refers to cut-off for Severe Traumatic Brain Injury
    2. Not-Tested (NT)
      1. Use NT to mark items that could not be tested (e.g. intubated patient)
      2. Example: E-1, V-NT, M-3
  • Precautions
  1. In Head Injury, document exactly what is seen (in addition to the score)
    1. Describe what painful did in response to painful stimuli (e.g. sternal rub, trapezius squeeze)
