Low-dose S-Ketamine and Postpartum Depression in Parturients With Prenatal Depression

Studies have shown that prenatal depression symptoms are important predictors of postpartum depression. Screening of pregnant women's mental condition before giving birth, early identification of pregnant women with symptoms of prenatal depression, and providing appropriate interventions may play an important role in reducing the incidence of postpartum depression. Ketamine is an NMDA‐receptor antagonist. In recent years, many studies confirmed that ketamine has a significant antidepressant effect. As a stereoisomer of ketamine, s‐ketamine has similar effects to ketamine in anti‐depression. In clinical application, s‐ketamine has stronger analgesic effect, better anesthetic effect and lower incidence of adverse psychological reactions. We speculate that, for pregnant women with prenatal depression, low‐dose s‐ketamine infusions after childbirth may reduce postpartum depression. Evidence is lacking in this regard.
