Summary
AI-generated from the abstractLow-dose intravenous esketamine given during and after cesarean section reduces postpartum depression scores. In a randomized, double-blind, placebo-controlled trial of 186 women aged 20-50 years, those receiving esketamine (either intraoperatively alone or combined with patient-controlled intravenous analgesia) showed greater reductions in Edinburgh Postnatal Depression Scale scores at 5, 7, and 14 days after surgery compared to placebo. Sleep quality, pain scores, and analgesic use did not differ between groups. Mild, temporary side effects were more frequent with combined esketamine and PCIA. The findings suggest esketamine is a safe and effective approach for lowering postpartum depression risk after cesarean delivery.

Abstract
To assess the impact of low-dose intravenous esketamine on postpartum depression scores in women undergoing cesarean section. In a randomized, double-blind, placebo-controlled trial, 186 women aged 20-50 years receiving epidural anesthesia for cesarean section were divided into three groups: Group A (0.25 mg/kg esketamine intraoperatively + esketamine in PCIA), Group B (0.25 mg/kg esketamine intraoperatively + PCIA without esketamine), and Group C (placebo intraoperatively + PCIA without esketamine). The primary outcome was the change in Edinburgh Postnatal Depression Scale (EPDS) scores. Secondary outcomes included Pittsburgh Sleep Quality Index (PSQI) scores, Visual Analogue Scale (VAS) scores, PCIA bolus frequency, and adverse events. EPDS and PSQI scores decreased significantly post-surgery across all groups (p < 0.05). Groups A and B showed greater EPDS score reductions than Group C at 5, 7 and 14 days postoperatively (p < 0.01). No significant differences were observed in PSQI scores, VAS scores or PCIA bolus frequency between groups. Adverse events though mild and transient, were more frequent in Group A (p < 0.01). Low-dose intravenous esketamine, reduces postpartum depression scores post-cesarean section, with a safe profile despite increased mild adverse events when combined with PCIA.
