摘要
近年临床上检测大脑 的技术和设备发展很快,包括脑电图(EEG)、诱发电位(EP)、双频谱分析(BIS)、近红外光谱脑氧饱和度(rScO_2)、经颅多普勒脑血流速(TCD)以及强有力的脑功能研究工具-正电子发射断层扫描(PET)和功能型磁共振成像(MRI)。PET和MRI提供了研究各种刺激条件下和认知过程中局部功能的变化。然而这些复杂的研究工具尚不适用于麻醉下的脑检测。目前临床上能够直接检测脑功能状态变化的仍是EEG,特别是经计算机化处理的定量脑电图(qEEG)和诱发电位。
There is rapid-ly increasing
interest in equipment for brain monitoring. It includes electroencephalogram (EEG), e-voked potentials(EP), bispectral analysis (BIS), near infrared spectroscopy, transcra-
nial Doppler blood velocity (TCD) and more powerful research tools such as positron e-mission tomography (PET) and functional magnetic resonance imaging (MRI).The use of PET and MRI to study various stimuli and cognitive tasks is to add considerably to our understanding of the functions of brain regions. But these tools are not suitable for brain monitoring during anesthesia. The EEG has' stili been recognizing the most useful and direct means of monitoring brain func-tion in the operating room, particulauly there now exists the Quantitative EEG and EP pre-processed by computer technology.
