What researchers measure

Primary outcomes

  1. Changes in baseline HDRS Score

    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.

    Time frame: 20 minutes before and 40 minutes after ketamine infusion.

  2. Daily change in HDRS post-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.

    Time frame: 1,2,3,4,5,6 and 7. Days after ketamine infusion

Secondary outcomes

  1. Baseline blood pressure (BP).

    Baseline BP will be measured during the physical examination 20 minutes before ketamine infusion.

    Time frame: 20 minutes before ketamine infusion.

  2. Changes from baseline in blood pressure (BP)

    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.

    Time frame: every 5 minutes in a 300 minutes period
