Abstract There are questions and challenges regarding neurologic complications in COVID-19 patients. EEG is a safe and efficient tool for the evaluation of brain function, even in the context of COVID-19. However, EEG technologists should not be put in danger if obtaining an EEG does not significantly advance diagnosis or change management in the patient. Not every neurologic problem stems from a primary brain injury: confusion, impaired consciousness that evolves to stupor and coma, and headaches are frequent in hypercapnic/hypoxic encephalopathies. In patients with chronic pulmonary disorders, acute symptomatic seizures have been reported in acute respiratory failure in 6%. The clinician should be aware of the various EEG patterns in hypercapnic/hypoxic and anoxic (post-cardiac arrest syndrome) encephalopathies as well as encephalitides. In this emerging pandemic of infectious disease, single-use subdermal EEG needle electrodes may be used in comatose patients. Full EEG montages using the 10-20 system, including a derivation for ECG, are strongly recommended so as to cover relevant temporal lobe regions. We recommend noting whether the patient is undergoing or has been placed prone, as well as noting the body and head position during the EEG recording (supine versus prone) to avoid overinterpretation of respiratory, head movement, electrode, muscle or other artifacts. There is slight elevation of intracranial pressure in the prone position. In non-comatose patients, the hyperventilation procedure should be avoided. At present, non-specific EEG findings and abnormalities should not be considered as being specific for COVID-19 related encephalopathy.

如何对 ICU 中的 COVID-19 患者进行脑电图记录并进行解读？

摘要：关于 COVID-19 患者的神经系统并发症存在问题和挑战。即使在 COVID-19 的背景下，脑电图也是评估大脑功能的安全有效的工具。然而，如果获得脑电图不能显着推进诊断或改变患者的治疗，脑电图技术人员不应面临危险。并非所有神经系统问题都源于原发性脑损伤：精神错乱、意识受损进而发展为昏迷和昏迷，以及头痛在高碳酸血症/缺氧性脑病中很常见。据报道，在患有慢性肺部疾病的患者中，6% 的患者在急性呼吸衰竭中出现急性症状性癫痫发作。临床医生应了解高碳酸血症/缺氧和缺氧（心脏骤停后综合征）脑病以及脑炎的各种脑电图模式。在这种新出现的传染病大流行中，一次性皮下脑电图针电极可用于昏迷患者。强烈建议使用 10-20 系统进行完整的脑电图蒙太奇，包括心电图的衍生，以覆盖相关的颞叶区域。我们建议注意患者是否处于俯卧状态，以及在脑电图记录期间注意身体和头部位置（仰卧与俯卧），以避免过度解释呼吸、头部运动、电极、肌肉或其他伪影。俯卧位时颅内压略有升高。对于非昏迷患者，应避免过度通气操作。目前，非特异性脑电图检查结果和异常不应被视为特定于 COVID-19 相关脑病。
