Brief Summary
This study evaluates whether ketamine, given as part of an anesthetic, improves depression symptoms in depressed patients undergoing non-cardiac surgery. Half of participants will receive a ketamine infusion during surgery, while the other half will receive a placebo (normal saline) during surgery.

Outcome Measures
Primary Outcomes (1)
Montgomery-Asberg Depression Rating Scale (MADRS) Score
The MADRS is a 10-item scale for the evaluation of depressive symptoms (Montgomery et al 1979). Each MADRS item is rated on a 0 to 6 scale. Total score range from 0-60, where lower MADRS scores indicate lower levels of depressive symptoms. The assessment for this outcome will be taken once daily on days 1, 2 and 3 post procedure. A mixed model for repeated measures (MMRM) was used to analyze the difference in postoperative MADRS score between ketamine and placebo groups..
