Objective:To explore safety and efficacy of artificial coma induction to treat status epilepticus (SE) immediately after first-line antiseizure treatment instead of following the recommended approach of first using second-line drugs.Methods:Clinical and electrophysiologic data of all adult patients treated for SE from 2017 to 2018 in the Swiss academic medical care centers from Basel and Geneva were retrospectively assessed. Primary outcomes were return to premorbid neurologic function and in-hospital death. Secondary outcomes were the emergence of complications during SE, duration of SE, ICU and hospital stay.Results:Of 230 patients, 205 received treatment escalation after first-line medication. Of those, 27.3% were directly treated with artificial coma and 72.7% with second-line non-anesthetic antiseizure drugs. Of the latter, 16.6% were subsequently put on artificial coma after failure of second-line treatment. Multivariable analyses revealed increasing odds for coma induction after first-line treatment with younger age, the presence of convulsions, and with an increased SE severity as quantified by the Status Epilepticus Severity Score (STESS). While outcomes and complications did not differ compared to patients with treatment escalation according to the guidelines, coma induction after first-line treatment was associated with shorter SE duration, ICU and hospital stay.Conclusions:Early induction of artificial coma is performed in more than every fourth patient and especially in younger patients presenting with convulsions and more severe SE. Our data demonstrate that this aggressive treatment escalation was not associated with an increase in complications but with shorter duration of SE, ICU and hospital stays.Classification of Evidence:This study provides Class III evidence that early induction of artificial coma after unsuccessful first-line treatment for SE is associated with shorter duration of SE, ICU and hospital stays compared to the use of a second-line non-anesthetic antiseizure drug instead or prior to anesthetics, without an associated increase in complications.
Objectives: To determine the frequency of advance directives or directives disclosed by healthcare agents and their influence on decisions to withdraw/withhold life-sustaining care in neurocritically ill adults. Data Sources: PubMed, Embase, and Cochrane databases. Study Selection: Screening was performed using predefined search terms to identify studies describing directives of neurocritically ill patients from 2000 to 2019. The review was registered prior to the screening process (International Prospective Register of Systematic Reviews identification number 149185). Data Extraction: Data were collected using standardized forms. Primary outcomes were the frequency of directives and associated withholding/withdrawal of life-sustaining care. Data Synthesis: Out of 721 articles, 25 studies were included representing 35,717 patients. The number of studies and cohort sizes increased over time. A median of 39% (interquartile range, 14–72%) of patients had directives and/or healthcare agents. The presence of directives was described in patients with stroke, status epilepticus, neurodegenerative disorders, neurotrauma, and neoplasms, with stroke patients representing the largest subgroup. Directives were more frequent among patients with neurodegenerative disorders compared with patients with other illnesses (p = 0.043). In reference to directives, care was adapted in 71% of European, 50% of Asian, and 42% of American studies, and was withheld or withdrawn more frequently over time with a median of 58% (interquartile range, 39–89%). Physicians withheld resuscitation in reference to directives in a median of 24% (interquartile range, 22–70%). Conclusions: Studies regarding the use and translation of directives in neurocritically ill patients are increasing. In reference to directives, care was adapted in up to 71%, withheld or withdrawn in 58%, and resuscitation was withheld in every fourth patient, but the quality of evidence regarding their effects on critical care remains weak and the risk of bias high. The limited number of patients having directives is worrisome and studies aiming to increase the use and translation of directives are scarce. Efforts need to be made to increase the perception, use, and translation of directives of the neurocritically ill.
OBJECTIVES: To identify early predictors of postictal delirium in adult patients after termination of status epilepticus. DESIGN: Retrospective study. SETTING: ICUs at a Swiss tertiary academic medical center. PATIENTS: Status epilepticus patients treated on the ICUs for longer than 24 hours from 2012 to 2018. INTERVENTIONS: None. METHODS: Primary outcome was postictal delirium during post-status epilepticus treatment defined as an Intensive Care Delirium Screening Checklist greater than or equal to 4. Associations with postictal delirium were secondary outcomes. A time-dependent multivariable Cox proportional hazards model was used to identify risks of postictal delirium. It included variables that differed between patients with and without delirium and established risk factors for delirium (age, sex, number of inserted catheters, illness severity [quantified by the Sequential Organ Failure Assessment and Status Epilepticus Severity Score], neurodegenerative disease, dementia, alcohol/drug consumption, infections, coma during status epilepticus, dose of benzodiazepines, anesthetics, and mechanical ventilation). MEASUREMENTS AND MAIN RESULTS: Among 224 patients, post-status epilepticus Intensive Care Delirium Screening Checklist was increased in 83% with delirium emerging in 55% with a median duration of 2 days (interquartile range 1–3 d). Among all variables, only the history of alcohol and/or drug consumption was associated with increased hazards for delirium in multivariable analyses (hazard ratio = 3.35; 95% CI, 1.53–7.33). CONCLUSIONS: Our study provides first exploratory insights into the risks of postictal delirium in adult status epilepticus patients treated in the ICU. Delirium following status epilepticus is frequent, lasting mostly 2–3 days. Our findings that with the exception of a history of alcohol and/or drug consumption, other risk factors of delirium were not found to be associated with a risk of postictal delirium may be related to the limited sample size and the exploratory nature of our study. Further investigations are needed to investigate the role of established risk factors in other status epilepticus cohorts. In the meantime, our results indicate that the risk of delirium should be especially considered in patients with a history of alcohol and/or drug consumption.
