Influences of dexmedetomidine on stress responses and postoperative cognitive and coagulation functions in patients undergoing radical gastrectomy under general anesthesia

Figure 2 Influence of dexmedetomidine on stress responses of gastric cancer patients undergoing radical gastrectomy under general anesthesia. A: Cortisol at different time points in two groups of gastric cancer (GC) patients undergoing radical gastrectomy (RG) under general anesthesia (GA); B: Adrenocorticotropic hormone at different time points in two groups of GC patients undergoing RG under GA. ^aP < 0.05 vs T1; ^dP < 0.05 vs T0; ^gP < 0.05 vs control group. T0: Before surgery; T1: 6 h after surgery; T2: 24 h after surgery; Cor: Cortisol; ACTH: Adrenocorticotropic hormone.
