Ketamine and Postoperative Depressive Symptom-PASSION

Abstract

Perioperative depression symptom (PDS) is one of the common mental comorbidity, and influences the clinical outcomes and prognosis. However, there is no rapid acting treatment to deal with it during the limited hospital stay. This study aims to determine whether ketamine could improve the depressive symptom of peirioperative patients. It will also examine the safety for administrating ketamine as an antidepressant intraoperatively. Meanwhile, it will show if ketamine could improve anxiety, postoperative pain or delirium. This trial also will bring great concerns on patients with perioperative mental health and explore the measures to improve their psycho-related prognosis.
