At the initiation of induction for non-intubated general anesthesia, ciprofol or propofol will be administered intravenously at a rate of 10 mL/min. The Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale will be used to evaluate sedation depth. This study aims to assess the effects of ciprofol and propofol on hemodynamics and respiratory function in elderly patients undergoing non-intubated general anesthesia.
