Preoperative Ketamine and Perioperative Depression

Depressive symptoms, in patients with a life history of major depressive disorder (MDD), are very common in the general population, and are especially so in elderly adults undergoing surgery.Symptoms of depression at the time of surgery is associated with risk for postoperative complications. Attenuating depressive symptoms in patients undergoing surgery is thus a plausible but not adequately tested strategy for improving patient postoperative outcomes. Conventional treatment of depression takes weeks and, therefore, is not always a realistic option, particularly when surgery is urgent. Importantly, there are currently no guidelines for diagnosing and managing MDD in surgical patients.

Given its association with complications including perioperative cognitive disorders such as delirium, and over longer periods of time with dementing disorders, the feasibility and efficacy of quick-acting treatments for depressive symptoms in surgical patients are direly needed. This need is particularly acute given the rising number of elderly patients undergoing surgery who are prone to depression and surgical complications.
