Purpose of the guideline: In severe patients with brain dysfunction, quantitative EEG monitoring can directly reflect EEG changes, capture characteristic pathology-like waves, evaluate the adequacy of cerebral blood flow, and assist in assessing the prognosis of patients with altered consciousness, so as to provide early warning of brain function abnormalities in patients, reflect the state of brain function of patients in real time at the bedside, and provide real-time monitoring and warning information for medical staff. When the function of CT and MRI is limited, it can provide the core information of abnormal brain function, which is conducive to timely diagnosis and accurate treatment of patients. In addition, these data can also provide a research basis for researchers to explore the pathogenesis and treatment of nervous system diseases, so as to provide a more scientific and accurate basis for disease prevention and treatment. Icu quantified EEG is a medical technology that must be mastered by ICU medical staff. Icu medical team should have the ability of quantified EEG on machine, real-time interpretation, obstacle removal and off machine independently. It provides very important support for the monitoring and treatment of critically ill patients and is an integral part of critical intervention. Considering the lack of homogeneity in the current domestic quantitative EEG monitoring in severe cases, this expert consensus is formulated in order to better guide relevant medical practitioners to carry out clinical practice, standardize and refine the operation and interpretation of quantitative EEG, and expand the application scope of quantitative EEG as much as possible.
