Outcome Measures
Primary Outcomes (1)
Hamilton Rating Scale for Depression
24-item Hamilton Depression Rating Scale, total score Higher values represent more severe depressive symptoms Maximum score, 76; minimum score, 0 Remission defined as total score \< 10 Response defined as decrease of total score from baseline \> 50%
3 weeks after baseline
Study Arms (1)
Propofol
EXPERIMENTALInterventions
Similar to the high-intensity propofol treatments in Phase 1, the anesthesiologist will administer an induction dose of propofol followed by a continuous infusion, insert an airway, and begin mechanical ventilation. Propofol dosing will be adjusted with the goal of achieving a burst-suppression state with a SR of 40-60 for 12-15 minutes.
