Randomized Controlled TrialKetamine Anesthesia Does Not Improve Depression Scores in Electroconvulsive Therapy: A Randomized Clinical Trial.
Although interest in ketamine use during electroconvulsive therapy (ECT) has increased, studies have been equivocal with regard to its efficacy. The aims of this clinical trial were to evaluate ketamine's antidepressive effects in ECT as a primary anesthetic, determine ketamine's tolerability when compared with standard anesthesia, and determine if plasma brain-derived neurotrophic factor (BDNF) is necessary for treatment response. ⋯ Our data show that ketamine does not significantly improve depression when compared with methohexital as a single induction agent for ECT, increases serum BDNF and does not increase rates of post-ECT agitation. Ketamine use in ECT may have some benefits for some patients that are not captured through standard depression assessment questionnaires alone.
