Trial Design

4Treatment groups
Active Control
Group I: ECT with EtomidateActive Control2 Interventions
Immediately prior to ECT study patients will be administered intravenous etomidate for anesthesia at a dose of 0.3 mg/kg given as a bolus dose.
Group II: ECT with KetamineActive Control2 Interventions
Immediately prior to ECT study patients will be administered intravenous ketamine for anesthesia at a dose of 0.5 -1.0 mg/kg given as a bolus dose.
Group III: ECT with Etomidate and HyperventilationActive Control3 Interventions
Immediately prior to ECT study patients will be administered intravenous etomidate for anesthesia at a dose of 0.3 mg/kg given as a bolus dose. Hyperventilation will be administered (20 breaths in 30 seconds) by face mask immediately prior to ECT.
Group IV: ECT with Ketamine and HyperventilationActive Control3 Interventions
Immediately prior to ECT study patients will be administered intravenous ketamine for anesthesia at a dose of 0.5 -1.0 mg/kg given as a bolus dose. Hyperventilation will be administered (20 breaths in 30 seconds) by face mask immediately prior to ECT.
