Figure 2 Comparison of hemodynamic parameters between the 2 groups of patients. A: Heart rate in beats per minute; B: Mean arterial pressure in mmHg; C: Oxygen saturation in %; D: Bispectral index. ^aP < 0.05 within the group relative to pre-anesthesia; ^bP < 0.05 within the group relative to immediately after extubation. T0: Pre-anesthesia; T1: Immediately after intubation; T2: At the time of pneumoperitoneum; T3: 30 minutes after the start of surgery; T4: Immediately after extubation. HR: Heart rate; bpm: Beats per minute; MAP: Mean arterial pressure; SOP₂: Oxygen saturation; BIS: Bispectral index.

Figure 3 Comparison of Riker Sedation-Agitation Scale and Mini Mental State Examination Scores between the 2 groups of patients. A: Riker Sedation-Agitation Scale Score; B: Mini Mental State Examination Score. ^aP < 0.05 within the group relative to 24 hours before surgery; ^bP < 0.05 within the group relative to 6 hours after surgery. RSAS: Riker Sedation-Agitation Scale Score; MMSE: Mini Mental State Examination Score.
