Abstract
Background: EEG reactivity has prognostic utility in
coma.
However, the relative effectiveness of various stimuli
has not been
systematically explored. Methods: We chose 200 adult
patients with
in coma in ICU and excluded patients who were brain dead
or on
anesthetic doses of sedative medication. EEGs were
recorded while
applying stimuli randomly: vocal stimulus (vS): calling
of the
patient's first name; "noisy stimulus" (NS): tone of 120
dB into both
ears; nasal stimulus (NaS): tissue paper inserted into
the nares;
nailbed stimulus (NBS): pressure on the nailbed of index
finger.
Results: The percentage in which reactivity to one
stimulus was
associated with reactivity to another stimulus is shown
in Table:
Conclusions: It is best to apply more than one stimulus
modality
when assessing EEG reactivity. With respect to
associations, NS is
the least effective stimulus
