摘要
本文运用了电子计算机叠加原理,对30例颅内血肿术后深昏迷患者进行了脑干诱发电位(AEP)检查和动态观察。分析了颅内动静脉畸形(2例)、脑外伤(20例)、高血压引起颅内出血(8例)所致脑干诱发电位潜伏期、波间期、峰值以及波形的变化,提出了深昏迷病人听觉脑干诱发电位的五种类型,即正常型(皮层广泛受损)、单纯幅值减低型(脑干功能低下)、潜伏期延长型(脑干听觉传导通路障碍)、波形分化型(脑干功能严重损害)、波形消失型(脑死亡)。此种分型对脑干不同部位功能损害的诊断、治疗及预后评估,具有一定的指导意义.
30 postaperative comatose patients, who were operated on for intracranial hemotomas due to AVM 2 cases, cerebral trauma 20 and hypertensive intracerebral hemorrhage 8, are examined and observed dynamiclly with AEP. On the basis of the principle of computer superposition. The authors analyse the changes of PL, IPL and AMP of AEP and propose 5 types of AEP of comatase pateints, that is normal type (extensive cortical lesions), simple low amplitude wave type AEP (lower function of brain stem), prolongated incubation period type AEP (obstruction of auditory conduction), disintegration of wave type AEP (functions of brain stem are seriously affected), and no wave type AEP (brain death). This typing of AEP is of benefit to diagnose to treat and to appreciate the prognoses of lesions of brain stem of different Part.
