Comparison of Propofol and Ketofol as Induction Agents for Electroconvulsive Therapy

NCT07273851 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 80

Last updated 2025-12-12

No results posted yet for this study

Summary

This randomized controlled trial will compare two anesthetic agents, propofol and ketofol (a combination of propofol and ketamine), in patients undergoing electroconvulsive therapy (ECT). Propofol is commonly used but may lower blood pressure, while ketofol may help maintain more stable cardiovascular function. The study will evaluate changes in systolic blood pressure following ECT when either propofol or ketofol is used for anesthesia induction. A total of 80 adult patients will be enrolled and randomly assigned to one of the two treatment groups. Findings may guide anesthesiologists in selecting the safest and most effective induction agent for ECT.

Conditions

Interventions

DRUG

Propofol

Intravenous induction agent administered before electroconvulsive therapy. Participants in this arm will receive IV propofol 1 mg/kg as a single slow bolus immediately before ECT under continuous ECG, pulse oximetry, and non-invasive blood pressure monitoring. Premedication with glycopyrrolate 0.004 mg/kg IV will be given to all patients. Ringer's lactate infusion will begin prior to induction. After loss of eyelash reflex, ECT will be performed using bifrontotemporal electrodes. Systolic blood pressure, heart rate, and oxygen saturation will be recorded at baseline and 20 minutes after shock delivery. The patient will be ventilated with 100 % oxygen until spontaneous breathing resumes.

DRUG

Ketofol

Intravenous admixture prepared immediately before induction by combining equal parts of ketamine and propofol in the same syringe. Participants will receive propofol 0.5 mg/kg + ketamine 0.5 mg/kg as a slow IV bolus immediately before ECT. Continuous ECG, pulse oximetry, and non-invasive blood pressure monitoring will be maintained. Premedication and procedural steps are identical to the propofol arm. The rationale is that ketamine's sympathetic stimulation counterbalances the hypotensive effect of propofol, potentially improving hemodynamic stability during ECT. Hemodynamic variables and seizure duration will be documented at baseline, during, and 20 minutes after shock delivery. Patients will receive 100 % oxygen ventilation until spontaneous respiration resumes.
