Conditions

Patients who undergo painless gastrointestinal endoscopy due to abdominal pain, acid reflux, functional gastrointestinal disease, or physical examination.

Interventions

Non-obese group:Based on the endoscopic insertion result of the previous patient, the ciprofol induction dose for the next patient is adjusted after a coin flip opera
