Results are calculated in your browser. Always double-check before administering and use your clinical judgement.
How it is calculated
MGCS = motor activity + brainstem reflexes + level of consciousness, each scored 1 (most severe) to 6 [1].
In the original study of dogs with head trauma, the MGCS predicted survival in the first 48 hours with 50% probability in a patient with a score of 8 [2]. Re-score serially to follow the effect of treatment [1].
Worked example
4 + 5 + 4 = 13.
