Clinical takeaway: Ketamine or esketamine administered during or shortly after an elective cesarean delivery contributed to a modest reduction in depressive symptoms in the initial two weeks postpartum. However, the extent to which this early improvement might lead to fewer cases of postpartum depression is still uncertain.
Recovery from a cesarean delivery coincides with a critical time for maternal mental health. Researchers are investigating whether the rapid antidepressant effects of ketamine could provide advantages beyond its traditional roles in anesthesia and pain management.
A meta-analysis showcased at ANESTHESIOLOGY 2026 revealed that administering ketamine or esketamine during or right after elective cesarean delivery resulted in a modest decrease in early postpartum depressive symptoms. These findings highlight a potential extra benefit of perioperative treatment, although they do not confirm a role for these medications in standard depression prevention practices.
This analysis encapsulated six randomized controlled trials involving a total of 1,832 women. Researchers compared outcomes of patients who received either ketamine or esketamine against those who received no medication, evaluating scores on the Edinburgh Postnatal Depression Scale between postoperative days 3 and 14.
Women treated with ketamine or esketamine showed a statistically significant, albeit small-to-moderate, reduction in depressive symptom scores. However, improved scores in a screening questionnaire do not definitively indicate that treatment prevented clinically diagnosed postpartum depression or that the benefits extended beyond the initial recovery phase.
The press release did not mention any adverse events resulting from the treatment. Key factors such as the optimal dosage, timing, and safety of employing these medications for reducing early postpartum depressive symptoms remain uncertain.
“Ketamine is recognized for its swift antidepressant effects in psychiatric environments, and our results indicate it may provide advantages beyond anesthesia and pain management for women undergoing a C-section,” stated lead researcher Peter Hsin, BS, a medical student at FIU Herbert Wertheim College of Medicine. “This is encouraging, but it is premature to conclude that ketamine prevents clinically diagnosed postpartum depression or that it should be a routine part of care.”
