This study aims to evaluate the sedative efficacy and safety of remimazolam combined with oliceridine in elderly patients undergoing painless gastrointestinal endoscopy. Elderly patients often face higher risks of respiratory and hemodynamic depression during clinical sedation. This trial will investigate whether the combination of remimazolam and oliceridine can provide stable sedation, maintain stable vital signs, and reduce the incidence of adverse events such as hypoxemia and postoperative cognitive fluctuation in this vulnerable population.
