Abstract:
Objective To investigate the predictive value of the 40 Hz auditory steady state response (40-Hz ASSR) in the short-term prognosis of patients with brainstem stroke.Methods The 40-Hz ASSR and brainstem auditory evoked potentials (BAEP) examinations were recorded and graded from 36 patients with brainstem stroke admitted in the Neurological Intensive Care Unit (NICU). Tue end point of short-term prognostic evaluation was at the time of leaving the NICU. Tue patients with brainstem stroke were divided into the survival group (n =21) and the death group (including brain death,n = 15). The correlation between the grade of the 40-Hz ASSR or BAEP and the short-term prognosis was analyzed. Results The grade of the 40-Hz ASSR (r=0.571,P =0.000) or BAEP (r =0.441,P =0.001 ) was significantly correlated with the short-term prognosis in patients with brainstem stroke. The sensitivity,specificity and accuracy of the 40-Hz ASSR were 60.00％,100％ and 83.33％,respectively,and those for BAEP were 66. 67％,71.43％ and 69. 44％,respectively. Conclusions Tue 40-Hz ASSR has a certain short-term prognostic value in patients with brainstem stroke. The higher the grade of 40-Hz ASSR is,the more serious the illness,and the worse the prognosis.
