Brainstem auditory evoked responses (BAERs) were recorded in 40 patients with clinically definite brainstem infarction, and results were compared to localizations from physical signs and CT scans. The BAER was abnormal in 92% of patients with evidence on physical examination of dysfunction of lateral structures in the pons or midbrain. Normal BAERs were seen with medially-situated or medullary lesions. When both rostrocaudal level and lateralization were considered, the BAER indicated damage in additional areas not evident on physical examination in 25% of patients. However, physical signs indicated damage in areas not reflected by the BAER in 22% of patients. Therefore, the BAER complements the localization obtained from physical findings. BAERs were abnormal in more of these patients than were CT scans, and thus are useful for confirmation of bedside impressions.
对40例临床确诊为脑干梗死的患者进行了脑干听觉诱发电位（BAERs）记录，并将结果与体格检查和CT扫描的定位结果进行比较。在92%有脑桥或中脑外侧结构功能障碍体格检查证据的患者中，BAER异常。在内侧或延髓病变患者中可见正常的BAER。当同时考虑前后水平和定位时，BAER显示25%的患者存在体格检查中未发现的其他区域损伤。然而，22%的患者体格检查显示存在BAER未反映区域的损伤。因此，BAER补充了从体格检查结果获得的定位信息。这些患者中BAER异常的比例高于CT扫描，因此有助于确认床边诊断印象。
