Comparative observation of the effectiveness and safety of remimazolam besylate versus dexmedetomidine in gastrointestinal surgery in obese patients

Figure 1 Vital signs of two groups of obese patients undergoing gastrointestinal surgery. A: Heart rate at different time points in the two groups; B: Respiratory rate at different time points in the two groups; C: Mean arterial pressure at different time points in the two groups; D: Blood oxygen saturation at different time points in the two groups. HR: Heart rate; RR: Respiratory rate; MAP: Mean arterial pressure; SpO₂: Blood oxygen saturation. ^aP < 0.05, ^bP < 0.01 vs T0; ^cP < 0.05 vs Con.
