Post Electroconvulsive Therapy Delirium and Anesthesia: A Randomised Clinical Study Comparing Thiopental, Propofol and Etomidate.

Various number of anesthetic agents are being used today but a very limited number of studies are based on comparing influence of different agents simultaneously on post ECT delirium. Keeping in view the above facts, we have taken up this study with the objective to examine the role of different anesthetic agents on post- ECT  delirium and to identify variables responsible for delirium after ECT. Each patient will undergo comprehensive evaluation .IQCODE will be used to assess the premorbid cognitive functioning.All patients to be oxygenated before ECT with  100% oxygen by mask. Continuous hemodynamic monitoring will be done. General anesthesia and paralysis will be induced by anesthetic agent and succinylcholine, respectively to achieve adequate depth of anesthesia. Brief Pulse ECT with bitemporal electrode placement  using half age method will be administered to the patient  using RMS PC ECTON machine (indigenous machine). Electrical parameters will be recorded.. Patient alertness will be assessed using Richmond Agitation- Sedation  Scale and delirium with Confusion Assessment Method for the ICU at 15 min, 30 min and 1 hour after eye opening.
