Primary Outcome Measures:
  • Changes in baseline HDRS Score [ Time Frame: 20 minutes before and 40 minutes after ketamine infusion. ]
    The Hamilton Depression Rating Scale (HDRS) baseline score will be measured 20 minutes before ketamine infusion. After 40 minutes post-infusion, a second HDRS score will be obtained.

  • Daily change in HDRS post-ketamine infusion. [ Time Frame: 1,2,3,4,5,6 and 7. Days after ketamine infusion ]
    On a daily basis, from day 1-7 post-ketamine infusion, changes in HDRS score will be measured during the daily psychiatric evaluation.


Secondary Outcome Measures:
  • Baseline blood pressure (BP). [ Time Frame: 20 minutes before ketamine infusion. ]
    Baseline BP will be measured during the physical examination 20 minutes before ketamine infusion.

  • Changes from baseline in blood pressure (BP) [ Time Frame: every 5 minutes in a 300 minutes period ]
    BP will be monitored continuously for a 4-hour period. BP assessments will be taken every five minutes for the period mentioned. The assessment will start 20 minutes before ketamine administration and will finish 4hrs after starting.


Estimated Enrollment: 60
