This clinical trial is focused on studying the effects of a combination of medications for patients with major depression undergoing a treatment called electroconvulsive therapy (ECT). The medications being studied are esketamine and propofol, which will be compared to another medication called methohexital. The purpose of the study is to see if the combination of esketamine and propofol is as effective and safe as methohexital when used during ECT.
Participants in the study will receive either the combination of esketamine and propofol or methohexital during their ECT sessions. The study will look at how well the medications help improve depressive symptoms and how quickly patients recover from anesthesia. The study will also monitor other factors such as blood pressure, heart rate, and any potential side effects on the liver and heart. The study will take place over a series of eight ECT sessions.
Throughout the study, researchers will assess various outcomes, including changes in cognitive function and the quality of the seizures induced by ECT. The study aims to ensure that the new combination of medications is not inferior to the current standard treatment with methohexital. Participants will be closely monitored to ensure their safety and well-being during the trial.
