Question: When should I do a CT scan in comatose patient?

Answer:

Although CT scans have revolutionized the practice of neurology, they are not indicated in every comatose patient. A good history, physical examination, and a few simple laboratory tests are adequate in most cases seen in the Emergency room because drug and alcohol abuse are common. If a structural lesion is suspected, however, a CT scan should be ordered immediately. If the condition of a patient with a suspected metabolic coma worsens or does not improve after a period of observation, a CT scan should be obtained.
