Etomidate-propofol combination in painless gastrointestinal endoscopy for elderly patients: A comparative study

Figure 1 Comparison of anesthesia quality. A: Comparison of anesthesia induction time; B: Comparison of recovery time; C: Comparison of orientation recovery time. ^bP < 0.01, compared to the control group.

Figure 2 Comparison of hemodynamic parameters. A: Heart rate levels across time points; B: Oxygen saturation levels across time points; C: Systolic blood pressure levels across time points; D: Diastolic blood pressure levels across time points. ^aP < 0.05 compared to T0; ^bP < 0.01 compared to T0; ^cP < 0.05, compared to the control group; HR: Heart rate; SpO₂: Oxygen saturation; SBP: Systolic blood pressure; DBP: Diastolic blood pressure.

Figure 3 Comparison of analgesic and sedative effects. A: Visual analog scale scores across time points; B: Ramsay scores across time points. ^bP < 0.01, compared to the control group; VAS: Visual analog scale.
