【Abstract】Objective To explore the effect of single sub-anaesthetic dose of ketamine on early postoperative mood and recovery quality in patients with radical breast cancer. Methods A total of 120 breast cancer patients admitted to our hospital from September 2018 to September 2019 were included in this study. The coin toss method was divided into two groups. Both groups of patients were planned to undergo radical breast cancer surgery. The operation was performed under the same anesthesia method. 60 patients in the control group were given a simple intravenous analgesia pump for postoperative analgesia, and 60 patients in the observation group were given a single sub-narcotic dose of ketamine + intravenous analgesia for postoperative analgesia. Patient anxiety, depression score, pain score and recovery quality score. Results In the third postoperative period, the SAS score and SDS score of the observation group were significantly lower than those of the control group. The number of anxiety and depression cases was less than the control group, the difference was significant (P<0.05); the body comfort and emotion of the observation group The state, psychological support, pain score and total score were higher than those in the control group, the difference was significant (P<0.05). Conclusion A single sub-anaesthetic dose of ketamine can quickly improve the early anxiety and depression of perioperative breast cancer patients, improve the quality of postoperative recovery of breast cancer patients, and benefit the postoperative recovery of patients. It is worth recommending.
