Interventions

Ciprofol group (Group C):Slowly inject 0.3-0.5 mg/kg of ciprofol intravenously
at the start of the gastrointestinal endoscopy, set the target sedation level to a MOAA/S score of <=1. If the subject experiences body movements or obvious swallowing movements during the procedure,
maintain a sedation depth MOAA/S score <= 2 points during the procedure.
Ciprofol + remazolam 0.05 mg/kg group (Group R1):Slow intravenous injection of 0.3-0.5 mg/kg ciprofol
at the start of gastrointestinal endoscopy, the target sedation level was set to MOAA/S score <= 1 point. After ciprofol anesthesia induction, Group R1 was slowly injected with 0.05 mg/kg of remimazol
the depth of sedation was maintained at MOAA/S score <=2 points during the operation.
Ciprofol + remazolam 0.1 mg/kg group (Group R2):Slow intravenous injection of 0.3-0.5 mg/kg ciprofol
at the start of gastrointestinal endoscopy, the target sedation level was set to MOAA/S score <= 1 point. After induction of anesthesia with ciprofol, Group R2 received a slow injection of 0.1 mg/kg o
