Application of Low-dose Muscle Relaxants in Bronchoscopic Interventional Procedures
Sponsor: Harbin Medical University
Summary
The purpose of this clinical trial is to observe the use of low-dose muscle relaxants in bronchoscopy intervention surgeries, compared with no muscle relaxants, in terms of the satisfaction of tracheal tube insertion after anesthesia induction, the incidence of laryngospasm, the grading of intraoperative cough and movement, and the recovery of patients after surgery. The main questions it aims to answer are: * How safe and feasible is the use of low-dose muscle relaxants in bronchoscopy intervention surgeries? * Is the muscle relaxant regimen better than the no-muscle-relaxant regimen? Participants will: * During anesthesia induction, the experimental group will use low-dose muscle relaxants for anesthesia, while the control group will not use muscle relaxants for anesthesia. * Record the satisfaction of mask ventilation and the incidence of laryngospasm.

Conditions
Interventions
Normal Saline (Placebo)
During anesthesia induction, an equal volume of normal saline was used instead of rocuronium for anesthesia.
Lidocaine Intravenous Infusion
Lidocaine was administered at a dose of 0.5mg/kg for the induction of anesthesia.
Remimazolam Tosilate
Remimazolam was administered at a dose of 0.2 mg/kg for the induction of anesthesia.
Remifentanil
Remifentanil was administered at a dose of 3 micrograms per kilogram for the induction of anesthesia.
Rocuronium (0.15mg/kg/body mass)
Rocuronium was administered at a dose of 0.15mg/kg for the induction of anesthesia.
