ADVERSE EVENTS, ADVERSE EVENT, EVENT, PREMATURE VENTRICULAR CONTRACTIONS
Routine heart rate monitoring, blood pressure monitoring, and electrocardiography were performed on all patients. For the assessment of SpOThe patient was placed in the lateral position and pre-oxygenated by deep breathing with 2 L minIn the event of inadequate alveolar ventilation during sedation, the investigators administered the following five interventions sequentially until all respiratory-related parameters returned to normal, recording the means of the last intervention: a: increasing oxygen flow (5 L/min); b: a chin lift or jaw thrust maneuver; c: placement of the nasopharyngeal airway and a chin lift; d: mask positive-pressure ventilation, and e: ventilator-assisted ventilation with tube insertion. The division of labor among participants was fixed throughout the experiment, and the gastroenterologist performed the endoscopy.After endoscopy completion, patients who can provide meaningful verbal responses and have stable vital signs were withdrawn from monitoring and transferred to the recovery room. Discharge was allowed when a post-anesthesia discharge scoring system (PADSS) (Table Adverse events were any instances where adverse symptoms and abnormal signs occurred after the application of the intervention, whether or not they were causally related to the trial. Any adverse events, including those provided voluntarily by the subject or identified through investigator inquiries and monitoring, were actively managed and closely followed until they resolved or stabilized. Adverse events of anesthesia sedation, including PONV, hypotension, bradycardia, and premature ventricular contractions occurred, were treated with ondansetron hydrochloride, atropine, noradrenaline, and lidocaine, respectively.
