OBJECTIVE: This study aims to investigate the effect of the pretreatment of S-ketamine on postoperative depression (POD) for breast cancer patients with mild/moderate depression. METHODS: The present randomized, double-blinded controlled trial included 303 breast cancer patients with mild/moderate depression from June 2017 to June 2018. All patients were randomly divided into three groups: (1) control group, patients treated with normal saline; (2) racemic ketamine group, patients treated with racemic ketamine; (3) S-ketamine group, patients treated with S-ketamine. Operation time, blood loss and hospital stay and complications were recorded. The Visual Analog Scale (VAS) score was recorded, and the Hamilton Rating Scale for Depression (HAMD-17) scores, serum brain-derived neurotrophic factor (BDNF) and 5-hydroxytryptamine (5-HT) were measured at three days, one week, one month and three months after surgery. RESULTS: No significant difference was found in operation time, bleeding volume and complication rate. In both groups, the VAS scores at one day and three days after surgery were significantly lower. The HAMD-17 scores were significantly lower, and the serum levels of both BDNF and 5-HT were remarkably higher at three days, one week and one month after surgery. Meanwhile, the HAMD-17 scores were remarkably lower, while the serum levels of BDNF and 5-HT were remarkably higher in the S-ketamine group. The BDNF and 5-HT levels were negatively correlated with the HAMD-17 score. CONCLUSION: S-ketamine is more effective for reducing POD for breast cancer patients.
