Postpartum depression (PPD) seriously impairs the physical and mental health of mothers and their offspring, so how to prevent the occurrence of PPD has essential significance. Esketamine is a common general anesthetic that produces rapid and sustained antidepressant effects. However, the efficacy and safety of perioperative esketamine administration for PPD prevention remain uncertain. We conducted a meta-analysis to determine the effect of perioperative intravenous esketamine on PPD. Randomized controlled trials were included. The primary outcome was the prevalence of PPD and postpartum Edinburgh Postnatal Depression Scale (EPDS) scores. Secondary outcomes included postoperative pain scores and esketamine-related adverse effects. Seven studies included 669 patients treated with esketamine and 619 comparisons. Esketamine could effectively reduce EPDS scores and the incidence of PPD after cesarean section. Even at 42 days postpartum, the incidence of PPD was still significantly lower in the esketamine group. Esketamine did not increase the incidence of postoperative nausea and vomiting, dizziness, and drowsiness. In the esketamine low-dose subgroup, postoperative nausea and vomiting were significantly lower in the esketamine group. The two groups had no significant difference in postoperative pain scores. In conclusion, using esketamine during the perioperative period can reduce the incidence of PPD without increasing adverse effects.
