“…Previous studies have shown that NCS/NCSE is frequently seen with acute brain insults with an incidence ranging between 8 and 48% depending on the patient population studied [1][2][3][4][5][6][7][8]. The etiology of NCS/NCSE in our patient population was comparable to previous reports stemming from both population-based [2] and retrospective studies [38].…”

“…The incidence of NCS and NCSE ranges between 8 and 48% depending on the patient population studied [1][2][3][4][5][6][7][8]. The mortality rate of neurologically critically ill patients afflicted with NCSE is 18-57% [9,10] while the presence of NCS is associated with a mortality rate of 33% [10].…”

“…We learn from this study that ESz and PEDs are also relatively frequent in critical patients without known primary neurological injury, confirming findings from a previous cohort, which also included some neurological patients [5]. It also indicates that patients with these EEG abnormalities may have worse prognosis.…”

“…The different patterns of EEG obtained in emergency patients, although nonspecific, can often be correlated with the etiology of diseases of the central nervous system such as trauma 4 , vascular injury and anoxic-ischemic injury due to cardiorespiratory arrest 5 . In hepatic encephalopathy 6,7 , Creutzfeldt-Jakob disease 8 , non-convulsive status epilepticus [9][10][11][12][13][14][15] and herpes simplex encephalitis 16 , EEG is decisive for diagnosis and thus guides therapy and gives an indication of the prognosis.…”

Objective: To determine the survival rate according to the main findings of emergency electroencephalography (EEGs) of patients treated in a tertiary hospital. Method: In this prospective study, the findings of consecutive emergency EEGs performed on inpatients in Hospital de Base in São José do Rio Preto, Brazil were correlated with survival utilizing KaplanMeyer survival curves. results: A total of 681 patients with an average age of 42 years old (1 day to 96 years) were evaluated, of which 406 were male. The main reasons for EEGs were epileptic seizures (221 cases), hepatic encephalopathy [116 cases of which 85 (73.3%) were men, p-value=0.001], status epilepticus (104 cases) and impaired consciousness (78 cases). The underlying disease was confirmed in 578 (84.3%) cases with 119 (17.5%) having liver disease [91 (76.0%) were men, p-value=0.001], 105 (15.4%) suffering strokes, 67 (9.9%) having metabolic disorders, 51 (7.5%) central nervous system infections and 49 (7.2%) epilepsy. In the three months following EEG, a survival rate of 75% was found in patients with normal, discreet slow activity or intermittent rhythmic delta activity EEGs, of 50% for those with continuous delta activity and generalized epileptiform discharges, and of 25% for those with burst-suppression, diffuse depression, and in alpha/theta-pattern coma. Death was pronounced immediately in patients with isoelectric EEGs. conclusion: The main findings of EEGs, differentiated different survival rates and are thus a good prognostic tool for patients examined in emergencies. Key words: EEG, emergency, prognosis, probability of survival.EEG de urgência: taxa de sobrevivência rEsuMO Objetivo: Determinar a taxa de sobrevivência (TS), segundo os principais achados de eletrencefalograma de urgência (E-EEG), dos pacientes atendidos nas emergências de hospital de alta complexidade. Método: Estudo prospectivo, por ordem de chegada, da correlação entre os achados de E-EEG, feitos nos pacientes à beira do leito, com TS, utilizando-se as curvas de sobrevidas de Kaplan Meyer no Hospital de Base de São José do Rio Preto, São Paulo/Brasil. resultados: Foram estudados 681 pacientes, dos quais 406 (59,6%) masculinos, com idade média de 42 anos (1 dia a 96 anos). As principais motivações para o E-EEG foram crises epilépticas (221 casos), encefalopatia hepática [(116 casos, dos quais 85 masculinos (73,3%), p= 0,001]; estado de mal epiléptico 104 e rebaixamento de consciência 78. O diagnóstico da doença de base foi confirmado em 578 (84,3%), sendo 119 (17,5%) hepatopatia, dos quais 91 (76,%) masculinos, p= 0,001; 105 (15,4%) acidente vascular encefálico; 67 (9,9%) distúrbio metabólico; 51 (7,5%) infecção do sistema nervoso central e 49 (7,2%) epilepsia. TS de 75% nos três primeiros meses foi encontrada nos pacientes com
