Brief Summary

Over the past decade, bronchoscopy technology has developed rapidly and has become an important part of the diagnosis and treatment of respiratory diseases. Bronchoscopy are usually carried out under monitored anesthesia care (MAC), which can relieve the anxiety of the patient, make the operation easier, and improve the completion rate of bronchoscopy. At present, bronchoscopy has widely used midazolam, propofol, short-acting opioids, and newer sedatives such as dexmedetomidine, but each drug has its limitations. Dexmedetomidine is widely used in non-intubation general anesthesia and sedation during short outpatient surgery. However, rapid and high-dose infusion of dexmedetomidine leads to dose-dependent hypotension, temporary hypertension, bradycardia, and excessive sedation, causing hemodynamic fluctuations. At the same time, it has slow onset and metabolism. This may be a potential risk for some elderly patients with many underlying diseases and unstable hemodynamics. Remimazolam is an ultra-short-acting benzodiazepine. It has the advantages of short action time, low accumulation, low risk of respiratory depression, and reversibility. We believe that remimazolam can improve the onset time and resuscitation time, to achieve sufficient sedation, improve the success rate of bronchoscopy, while reducing the patient's oxygen saturation drop during the operation, postoperative opioid-related nausea and vomiting, postoperative delirium and other related adverse events. This study is a randomized controlled trial to confirm the above hypothesis.

Outcome Measures

Primary Outcomes (2)

  • Incidence of Decreased Oxygen Saturation [ Safety]

    Oxygen Saturation\<90%, more than 30s

    Within 1 hour after the operation

  • Interruption Rate of Bronchoscopy [effectiveness]

    the occurrence of body movement or coughing makes the operating physician have to suspend the operation for physical restraint or adding drugs

    Within 1 hour after the operation

Secondary Outcomes (10)

  • Blood Pressure

    Within 1 hour after the operation

  • Heart Rate

    Within 1 hour after the operation

  • Hemodynamic variable

    Within 1 hour after the operation

  • Respiratory Rate

    Within 1 hour after the operation

  • Anesthesia onset time

    Within 1 hour after the operation

  • +5 more secondary outcomes

  • Before the study, the patients voluntarily signed and dated the informed consent form approved by the institutional review board.

You may not qualify if:

  • Patients with known allergies to benzodiazepines, flumazenil, opioids, naloxone or certain drugs.
  • Patients with long-term use of benzodiazepines or opioids.
  • Patients with a history of drug abuse or alcohol abuse in the past two years.
  • Bradycardia (baseline HR \<60bpm) or hypotension (baseline SAP\<100mmHg).
  • Asthma or chronic obstructive pulmonary disease(COPD) or FEV1\<1.0L.
  • SpO2 \<90% before bronchoscopy.
