脑死亡是指全脑功能不可逆停止。目前,诊断脑死亡尚无统一标准。除临床体征外,可应用同位素脑扫描、颈动脉造影、脑电图和脑诱发电位等判断脑死亡,但各有不足之处。应用多功能床边监护仪对危重病人进行连续脑电监测,对早期发现及正确诊断脑死亡有一定的作用。我科应用光电BSM-8301K型多参数床边监护仪,对所收治的神经外科 Brain death refers to irreversible cessation of whole brain function. At present, there is no uniform standard for diagnosing brain death. In addition to clinical signs, brain isotope scintigraphy, carotid artery angiography, EEG and brain evoked potentials can be used to determine brain death, but each has its own shortcomings. The continuous EEG monitoring of critically ill patients with multifunctional bedside monitor has a certain effect on the early detection and correct diagnosis of brain death.
