在非工作时间提供脑电图的管理和可用性政策在脑电图实验室之间差别很大。作者调查了经认可的脑电图实验室的医学主任（n = 84），以确定批准持续可用紧急脑电图（E-EEG）的可用性范围和临床适应症。在46名受访者中。37例（80%）提供E-EEG。两个研究中心最近失去了电子脑电图的资助。可用性与每年执行的脑电图总数无关。从请求到专家解释的平均估计响应时间为3±4小时（范围1-24小时）。大多数受访者认可e - eeg的五个临床适应症是可能的非惊厥性癫痫持续状态（100%）和治疗癫痫持续状态（84%）。脑死亡检查（81%），惊厥癫痫持续状态诊断（79%），昏迷或脑病诊断（70%）。当被问及哪些临床情况值得使用E-EEG时，受访者的意见大相径庭。有些人同意所有的请求，有些人拒绝除了非惊厥性癫痫持续状态。目前广泛的实践表明，需要对积极的脑电图辅助患者评估和治疗的结果进行研究，以更好地确定持续可用的脑电图服务的成本和收益。
Policies of administration and availability of EEG offered during nonbusiness hours vary widely among EEG laboratories. The authors surveyed medical directors of accredited EEG laboratories (n = 84) to determine the ranges of availability and clinical indications for approval of continuously available emergent EEG (E-EEG). Of 46 respondents. 37 (80%) offered E-EEG. Two centers recently lost funding for E-EEG. Availability was not associated with the total number of EEGs performed annually. The mean estimated response time from request to expert interpretation was 3 +/- 4 hours (range, 1-24 hours). The five clinical indications for which most respondents approved E-EEGs were possible nonconvulsive status epilepticus (100%), treatment of status epilepticus (84%). cerebral death exam (81%), diagnosis of convulsive status epilepticus (79%), and diagnosis of coma or encephalopathy (70%). Respondents disagreed widely when asked which clinical situations merited E-EEG. with some approving all requests and others denying all except for nonconvulsive status epilepticus. The wide range of current practice suggests that research focused on outcomes of aggressive, EEG-aided patient evaluation and treatment are needed to define better the costs and benefits of a continuously available EEG service.
