FOUR score

Q: FOUR score is useful in assessing? (select one)

A) Mental unresponsiveness 

B) Ventilator extubation parameter

Answer: A

FOUR stands for 'Full Outline of UnResponsiveness'. It is usually performed in Traumatic Brain Injury (TBI). It should be performed with Glasgow coma scale (GCS) to grade injury in intubated patients as well as to assess brain stem function. It is found to be as valuable as GCS in TBI to predict long-term outcomes.

It consists of four parameters.

1. Eye response

2. Motor response

3. Brainstem reflexes

4. Respiration
