Figure 1 Comparison of physiological stress indices (mean ± SD). A: Comparison of heart rate (times/min) at different time points; B: Comparison of mean arterial pressure (mmHg) at different time points; C: Comparison of superoxide dismutase (U/mL) at different time points; D: Comparison of malondialdehyde (mmol/L) at different time points; ^aP < 0.05. HR: Heart rate; MAP: Mean arterial pressure; SOD: Superoxide dismutase; MDA: Malondialdehyde; T₀: Before anesthesia; T₁: 30 min after anesthesia; T₂: At the conclusion of surgery; T₃: 1 h following surgery.
