Brief summary
The purpose of the study was to investigate the effects of etomidate or sevoflurane used in electroconvulsive therapy (ECT) on duration of seizure, hemodynamic response and recovery profiles.
Detailed description
Twenty-five patients will be a total of 150 ECT treatments in this prospective, double-blinded, crossover study. Each patient will receive either 0.2 mg/kg etomidate (Group 1) or 8% sevoflurane (Group 2) in 100% oxygen at 6 L/min fresh gas flow until loss of consciousness for their initial electroconvulsive therapy session. In subsequent sessions, patients will receive the alternative sevoflurane concentration and then alternated between doses until the sixth session. Muscle paralysis will achieve with 1 mg/kg succinylcholine. Motor (EMG) and electroencephalography seizure duration (EEG), heart rate (HR) and mean arterial pressure (MAP) values, and recovery times will recorde.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Motor (EMG) seizure duration | intraoperative | Motor seizure duration in electroconvulsive therapy |
| electroencephalography (EEG) seizure duration | intraoperative | seizure duration in electroconvulsive therapy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| heart rate (HR), | (approximately 5 minutes for all measurements) prior to the seizure, after the anesthetic induction, and following the ECT session at 1 minute, 3 minutes, and 10 minutes | heart rate in electroconvulsive therapy |
| mean arterial pressure (MAP) | (approximately 5 minutes for all measurements) prior to the seizure, after the anesthetic induction, and following the ECT session at 1 minute, 3 minutes, and 10 minutes | MAP will be measured by a blood pressure cuff |
| recovery times | (approximately 5 minutes for all measurements) prior to the seizure, after the anesthetic induction, and following the ECT session at 1 minute, 3 minutes, and 10 minutes | Recovery times will be assessed with spontaneous breathing, eye opening, obeying commands times |
