Summary

There are many different types of intravenous anesthetics used in gastroscopy, but each type of drug has its advantages and disadvantages,remimazolam is a novel ultra-short-acting benzodiazepine with rapid onset and recovery, low circulatory depression, and rapid reversal of sedation by flumazenil,remimazolam may be another relatively ideal sedative-hypnotic option for anesthesiologists and gastrointestinal endoscopists. The purpose of this study was to explore whether remimazolam combined with propofol is safer and more effective than remimazolam alone or propofol alone in gastrointestinal endoscopy.

Detailed description

Sedation for gastroscopy is still a topic of debate in the global anesthesia and gastroenterology communities, and the sedation protocols of anesthesiologists and endoscopists vary widely. There are many different types of intravenous anesthetic drugs used in gastroscopy, but each type of drug has its advantages and disadvantages, and the most common protocol in anesthesia practice is an opioid (e.g., fentanyl) combined with a sedative-hypnotic drug (e.g., propofol and midazolam). But these protocols usually have limitations with propofol mainly focusing on respiratory depression and circulatory depression, in which perioperative hypotension should be considered a serious public health problem and should be taken seriously by clinicians, while midazolam has a long onset of action and a long recovery time. Therefore, there is an urgent clinical need for a fast-onset, fast-recovery drug with a high safety profile to solve this current dilemma. As a new ultra-short-acting benzodiazepine with rapid onset and recovery, low circulatory depression, and rapid reversal of sedation by flumazenil, remimazolam may be another relatively ideal sedative-hypnotic option for anesthesiologists and gastrointestinal endoscopists. The drug was approved for procedural sedation in 2020, and there are many studies on the use of remimazolam versus propofol in gastrointestinal endoscopy sedation. A non-inferiority clinical study of remimazolam tosilate in the upper gastrointestinal tract showed that remimazolam had a sedation success rate no lower than that of propofol, a longer onset of sedation than propofol, but a shorter time to full consciousness than propofol, and a significantly lower incidence of adverse events than propofol. These findings suggest that remimazolam is indeed safer than propofol, but its depth of sedation may be inferior to that of propofol. For clinical workers, it is also essential to have good depth of sedation while ensuring safety. Therefore, considering the above, we hypothesized that the use of remimazolam in combination with propofol in gastrointestinal endoscopy could meet clinical sedation needs and also reduce the incidence of respiratory depression and circulatory depression, which have not been reported. The purpose of this study was to determine whether remimazolam combined with propofol is safer and more effective than remimazolam alone or propofol alone in gastrointestinal endoscopy.
