Remimazolam and Remifentanil Use Induced Severe Respiratory Depression and Laryngeal Spasm During Intravenous Sedation and Analgesia: A Case Report

Introduction: Intravenous sedation and analgesia are widely used in minor surgeries. Remifentanil and remimazolam are advantageous in this setting because of their rapid onset of action, and short duration of action leading to a rapid recovery. However, the two drugs combined need to be titrated to avoid airway-related adverse events.Case Presentation: This article reports a case of severe respiratory depression and severe laryngeal spasm induced by remifentanil and remimazolam when they were used for analgesia and sedation in a patient undergoing oral biopsy.Conclusion: We aim to improve awareness about the safety of these drugs among anesthesiologists and increase their ability to manage the risk associated with their use.
