简要总结
The authors hypothesized that inhaled sedation, either with isoflurane or sevoflurane, might be associated with improved clinical outcomes in patients with COVID-19-related ARDS, compared to intravenous sedation.
The authors therefore designed the "Inhaled Sedation for COVID-19-related ARDS" (ISCA) non-interventional, observational, multicenter study of data collected from the patients' medical records in order to:
- assess the efficacy of inhaled sedation in improving a composite outcome of mortality and time off the ventilator at 28 days in patients with COVID-19-related ARDS, in comparison to a control group receiving intravenous sedation (primary objective),
- investigate the effects of inhaled sedation, compared to intravenous sedation, on lung function as assessed by gas exchange and physiologic measures in patients with COVID-19-related ARDS (secondary objective),
- report sedation practice patterns in critically ill patients during the COVID-19 pandemics (secondary objective).
详细描述
The acute respiratory distress syndrome (ARDS) is the most severe and lethal complication of COVID-19, and healthcare resource utilizations are currently being heavily challenged in most countries worldwide, with a high risk that some intensive care resources, such as the number of ventilators to allow management all patients, may be insufficient to face the current surge in ARDS cases. There is, therefore, an urgent need to evaluate candidate therapies that may impact clinical outcomes in patients with COVID-19-related ARDS and potentially be relevant to current public health issues, in accordance with the international efforts by the World Health Organization (WHO) (Global research on coronavirus disease) and most international public health organizations. Beyond the current efforts to find specific antiviral therapies or vaccines, improving supportive care and treatment options for patients with COVID-19-related ARDS, in accordance with up-to-date guidelines on the management of critically ill patients with COVID-19 (Surviving Sepsis Campaign: Guidelines on the Management of Critically Ill Adults with Coronavirus Disease 2019; The Australian and New Zealand Intensive Care Society (ANZICS) COVID-19 Guidelines; Recommandations d'experts SRLF-SFAR-SFMU-GFRUP-SPILF sur la prise en charge en réanimation des patients en période d'épidémie à SARS-CoV2), is of major importance.
Indeed, given the number of intensive care unit (ICU) patients for whom the question of sedation applies during the current COVID-19 outbreak, any sedation practice that would be associated with improved clinical outcomes could have significant economic and public health implications. In this perspective, the rationale supporting inhaled sedation with halogenated agents (such as isoflurane or sevoflurane) as a way to improve lung function, to decrease the inflammatory response, and to possibly improve patient outcome is strong.
The authors hypothesized that inhaled sedation, either with isoflurane or sevoflurane, might be associated with improved clinical outcomes in patients with COVID-19-related ARDS, compared to intravenous sedation. The authors, therefore, designed the "Inhaled Sedation for COVID-19-related ARDS" (ISCA) non-interventional, observational, multicenter study of data collected from the patients' medical records in order to :
- assess the efficacy of inhaled sedation in improving a composite outcome of mortality and time off the ventilator at 28 days in patients with COVID-19-related ARDS, in comparison to a control group receiving intravenous sedation (primary objective),
- investigate the effects of inhaled sedation, compared to intravenous sedation, on lung function as assessed by gas exchange and physiologic measures in patients with COVID-19-related ARDS (secondary objective),
- report sedation practice patterns in critically ill patients during the COVID-19 pandemics (secondary objective).
This study will be performed in accordance with the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement.

结局指标
主要结局
Number of days off the ventilator (VFD28, for ventilator-free days), taking into account death as a competing event
时间窗: Day 28 after inclusion
Ventilator-free days to day 28 are defined as the number of days from the time of initiating unassisted breathing to day 28 after intubation, assuming survival for at least two consecutive calendar days after initiating unassisted breathing and continued unassisted breathing to day 28. If a patient returns to assisted breathing and subsequently achieves unassisted breathing to day 28, VFDs will be counted from the end of the last period of assisted breathing to day 28. A period of assisted breathing lasting less than 24 hours and for the purpose of a surgical procedure will not count against the VFD calculation. If a patient was receiving assisted breathing at day 27 or died prior to day 28, VFDs will be zero. Patients transferred to another hospital or other health care facility will be followed to day 28 to assess this endpoint.
