A 25-year-old motorcycle rider is brought to the emergency with history of motor vehicle accident. On primary survey, he is found to open eyes in response to pain, speaking inappropriate words and localizes pain. His Glasgow Coma Scale score is
$E_2 V_3 M_5$
The correct answer is E2 V3 M5, total GCS 10. Eye opening: 4 spontaneous, 3 to voice, 2 to pain, 1 none. Verbal: 5 oriented, 4 confused conversation, 3 inappropriate words, 2 incomprehensible sounds, 1 none. Motor: 6 obeys commands, 5 localises pain, 4 withdraws, 3 abnormal flexion (decorticate), 2 extension (decerebrate), 1 none. This patient scores 2 + 3 + 5 = 10, placing him in the moderate head injury band (9-12).
E3 V4 M4 would mean eye opening to voice, confused speech and withdrawal, none of which fits. E3 V3 M4 wrongly upgrades eye opening to voice and downgrades localising to withdrawal. E2 V4 M5 has the correct eye and motor scores but calls the speech confused conversation (V4), whereas isolated inappropriate words are V3.
Key point: Localising (M5) versus withdrawal (M4) depends on whether the hand crosses the midline towards the stimulus. GCS 13-15 mild, 9-12 moderate, 8 or less severe and needs a definitive airway.
