REmimazolam Infusion in the Context of Hypnotic Shortage in the Critical Care Unit During the Pandemic of COVID-19: REHSCU Study

REmimazolam Infusion in the Context of Hypnotic Shortage in the Critical Care Unit During the Pandemic of COVID-19. The Non-randomized, Non-controlled, Pilot, Open, Mono-centric REHSCU Study

The worldwide COVID-19 pandemic has led to a dramatic increase in the number of patients hospitalized in intensive care units for an acute respiratory failure in all countries. This situation has quickly led to massive shortage in masks, mechanical ventilation machines and common medications such as hypnotics. All countries over the world are currently experiencing a major shortage in basic hypnotic medications (propofol, midazolam) in the intensive care as well as in the operating theatre. The Principal Investigator proposes to perform a pilot study assessing the benefit-risk ratio of Remimazolam (a novel benzodiazepine with a short half-life) in the critical care units of Nantes University Hospital during the COVID-19 pandemic.

The worldwide COVID-19 pandemic has led to a dramatic increase in the number of patients hospitalized in intensive care units for an acute respiratory failure in all countries. This situation has quickly led to massive shortage in masks, mechanical ventilation machines and common medications such as hypnotics. The reasons for such shortage are multiple: dramatic increase of the demand, production discontinuation because of shutdowns in multiple countries, and withholding of products by producing countries. All countries over the world are currently experiencing a major shortage in basic hypnotic medications (propofol, midazolam) in the intensive care as well as in the operating theatre. Remimazolam is a novel benzodiazepine with a short half-life that has been administered in patients undergoing major surgery, as well as in the intensive care unit. The Principal Investigator proposes to perform a pilot study assessing the benefit-risk ratio of Remimazolam in the critical care units of Nantes University Hospital during the COVID-19 pandemic.
