Glasgow Coma Scale (GCS)
                        ========================

  - according to original authors, use _best_ score (i.e., if exam is
    asymmetric, use best side).
  - periorbital edema: eye-opening score of 1
  - intubated:  verbal score of 1
  - Prehospital GCS doesn't correlate with ultimate outcome at all; ED scores
    somewhat better but still poor.  [Winkler, J Emerg Med, 1984]
  - Withdrawal vs flexor response: withdrawal is fast with abduction at
    shoulder.  Some limb flexor spinal responses may remain even if brain dead.
  - Presby neurosurgery recommendations (Donald Marion, M.D., 3/92)  Test after
    stable (respiratory, hemodynamic); 30-45 minutes after meds; use norcuron
    and Fentanyl instead of Versed to make neurosurgeon's evaluation more
    reliable; supraorbital nerve stimulus.
