Effect of Subanesthetic Dose of Ketamine Combined With Propofol on

Status Not yet recruiting

Clinical Trial Summary

Electroconvulsive therapy (ECT) is an effective treatment for depression compared with the current antidepressant agents，but the most important side effect is cognitive dysfunction. The purpose of this study is to determine whether subanesthetic dose of ketamine combined with propofol is superior to propofol anesthesia alone in improving cognitive function in depressive patients undergoing ECT.

Clinical Trial Description

Depression is one of the most debilitating and widespread illnesses affecting up to 20% of individuals in their lifetime. However, the current antidepressant agents take weeks to work, and fail to help at least 40% of depressed patients. Electroconvulsive therapy (ECT) is a remarkably effective treatment for depression, but its use is limited by cognitive dysfunction.

As a result, it is becoming a clinical problem which need to be settled urgently. Previous clinical study showed that subanesthetic dose of ketamine could play a role in antidepressant effects with safety and minimal positive psychotic symptoms.The investigators also found that subanesthetic dose of ketamine combined with other anesthetics could improve cognitive function in depressive rats receiving electroconvulsive shock (a model for analogy with ECT). Few clinical researches concerned the effects of subanesthetic dose of ketamine combined with propofol anesthesia on cognitive function in patients after ECT, therefore the investigators conduct this randomized controlled double-blind trial. In this study, cognitive function will be rated by Mini-Mental State examination score. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
