Outcome Measures
Primary Outcomes (1)
Hamilton Depression Rating Scale at 24 hours, change from baseline
total score on the 17-item Hamilton Depression Rating Scale
24 hr
Study Arms (2)
Ketamine
EXPERIMENTALKetamine will be infused via intravenous catheter over 40 minutes (0.75 mg/kg/hr over 40 minutes, 0.5 mg/kg total).
Placebo
PLACEBO COMPARATORNormal saline will be infused via intravenous catheter over 40 minutes (0.75 mg/kg/hr over 40 minutes, 0.5 mg/kg total).
Interventions
Study drug will be infused while the participant sits or lies in a comfortable position. The dose of ketamine used does not cause unconsciousness but may cause perceptual disturbances.
