Study summary

This study is a prospective, randomized, controlled (randomized, parallel group, concealed allocation), double-blinded trial. All depression patients undergoing breast cancer operation will be randomized 1:1 to the treatment intervention with general anesthesia as an adjunct to esketamine or saline. The objective of the trial is to evaluate the postoperative depression、gut microbiota、bispectral index data of patients undergoing breast cancer operation with esketamine or saline.

Read the detailed description

For female patients, breast cancer patients have a high risk of developing depression, and approximately 20%-45% of breast cancer patients suffer from postoperative depression. Esketamine is an anesthetic in analgesia, and has presently become more and more popular for treating anti-depression, particularly for resistant depression.
