Parameters and grading of evoked potentials: prediction of unfavorable outcome in patients with severe stroke

To explore the prognostic accuracy for unfavorable outcome with short-latency somatosensory evoked potential (SLSEP) and brainstem auditory evoked potential (BAEP) in patients with severe stroke, 100 acute severe supratentorial stroke patients [Glasgow Coma Scale, (GCS) 0.4). Prognostic accuracy of SLSEP, BAEP, and GCS for unfavorable outcome was very high (94.3%-98.7%), among which BAEP is the highest (97.5%-98.7%). The overall prognostic accuracy of SLSEP (90.5%-93.7%) was higher than BAEP (83.0%-89.4%) and GCS (82%). The prognostic accuracy of SLSEP and BAEP for unfavorable outcome in patients with severe supratentorial stroke was high, whereas for favorable outcome, it was low. The overall prognostic accuracy was higher than GCS.
