Fig. 4From: Efficacy of esketamine for the treatment of postpartum depression and pain control following cesarean section: a randomized, double-blind, controlled clinical trialStress hormone expression levels between control and esketamine groups on postoperative day 3. A FC expression levels between the two groups on postoperative day 3. B comparison of the expression levels of ANP between the two groups on the 3rd post-operative day. C expression levels of Ebetween the two groups on postoperative day 3. D NE expression levels between the two groups on postoperative day 3. ****Indicates a significant decrease in FC, ANP, E and NE in the esketamine group compared to the control group (P < 0.0001). FC, free cortisol; ANP, atrial natriuretic peptide; E, epinephrine; NE, norepinephrineBack to article page
