  Purpose
When undergoing ECT treatments, patient recovery time and re-orientation time may be shorter using ketamine for induction than using methohexital.

Condition Intervention
Post-anesthesia Recovery Orientation Drug: Ketamine Drug: Methohexital

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Re-orientation Time [ Time Frame: 1 hour ]
    Patients will be scored based on 5 questions (name, age, year, day of week, location). Each patient will be scored prior to induction as to how many questions they score correctly. Patient is deemed re-oriented when they score the same as baseline after the treatment.

  • Recovery Time [ Time Frame: 1 hour ]
    Recovery was assessed using 5 criteria (blood pressure, voluntary movement, oxygen requirement, consciousness, respiratory effort). Each criteria was scored from 0-2, with a full score of 10. The patient is scored at baseline, and is deemed recovered when all criteria has reached baseline score again.

Arms Assigned Interventions
Experimental: Ketamine First
This arm will receive ketamine for induction first, followed by alternating treatments between methohexital and ketamine
Drug: Ketamine
Ketamine (1.5mg/kg) will be given for induction, with room to titrate up to induction effect
Drug: Methohexital
Methohexital (1.5mg/kg) will be given for induction
Experimental: Methohexital First
This arm will receive Methohexital first for induction, followed by alternating treatments between ketamine and methohexital.
Drug: Ketamine
Ketamine (1.5mg/kg) will be given for induction, with room to titrate up to induction effect
Drug: Methohexital
Methohexital (1.5mg/kg) will be given for induction

Detailed Description:
ECT treatments are done under general anesthesia, and the induction is commonly done with methohexital. We will study whether using ketamine as an induction agent will result in a faster recovery time and quicker re-orientation time compared to using methohexital.
