Abstract：Objective To investigate changes of brainstem auditory evoked potential (BAEP) and somatosensory evoked potential (SEP) in patients with acute cerebral infarction, and discuss their relation with prognosis of the patients. Methods The study involved 60 patients with acute cerebral infarction. Changes of BAEP and SEP in each patient were detected and recorded continuously. Prognosis evaluation was performed by using GCS. Another 60 age-matched and gender-matched healthy human beings were enrolled as controls. Results Incubation period of BAEP wave Ⅰ had no significant difference between the cerebral infarction and control groups (P>0.05). However, interspike intervals of other BAEP waves in cerebral infarction group were different from those in control group (P<0.05). A series of waves of SEP (P14-N60) were all significantly prolonged in cerebral infarction group (P<0.05). Conclusion BAEP and SEP can effectively reflect function of brain stem in patients with acute cerebral infarction and have some values in determining their prognosis.
