Summary
High-dose S-ketamine (0.5 mg/kg) significantly reduced pain and depression scores one and three days after surgery in cervical carcinoma patients with mild to moderate depression, compared to low-dose S-ketamine, racemic ketamine, or a control. The high-dose group also showed higher serum levels of BDNF and 5-HT at those time points. However, no differences between groups remained one week after surgery. Low-dose S-ketamine (0.25 mg/kg) and racemic ketamine did not produce significant improvements. The findings suggest that subanesthetic S-ketamine offers short-term benefits for postoperative depression and pain in this population, with the higher dose being more effective than racemic ketamine.

Abstract
Background This study investigated the effects of various doses of S-ketamine on depression and pain management of cervical carcinoma patients with mild/moderate depression. Material/Methods This randomized, double-blind, controlled study included 417 cervical carcinoma patients who received laparoscopic modified radical hysterectomy from April 2015 to July 2018 and who also had mild/moderate depression symptoms based on HAMD-17 scores (8~24). All patients were randomized into 4 groups: 1) the control group, 2) the racemic ketamine group, 3) the high-dose S-ketamine group; and 4) the low-dose S-ketamine group. Pain was assessed using the Visual Analogue Score (VAS), and depression was assessed using theHAMD-17 score. Serum levels of BDNF and 5-HT were measured. Results The 4 groups of patients showed no significant differences in operation time, bleeding volume, hospitalization duration, or complications. The high-dose S-ketamine group showed significantly lower VAS and HAMD-17 scores than all other groups at 1 day and 3 days postoperatively, but no differences were observed in the low-dose S-ketamine group and the racemic ketamine group. The high-dose S-ketamine group showed significantly higher serum BDNF and 5-HT levels at 1 day and 3 days after surgery. However, 1 week after surgery, no difference was observed in any of the treatment groups. Conclusions At subanesthetic dose, both 0.5 mg/kg and 0.25 mg/kg S-ketamine improved short-term depression and pain for cervical carcinoma patients after surgery, and the effects were better than with the same dose of racemic ketamine.
