Thiopentone sodium versus propofol for anaesthesia in modified electro-convulsive therapy (ECT)

Abstract


 Objectives: To compare the effects of thiopentone sodium and propofol as an intravenous anaesthetic agent in modified ECT. Methods: 100 patients of ASA I & II grade were randomly assigned in to two groups. Both groups were premedicated in ususal manner. Patients in Group A were induced with inj. thiopentone sodium 3-5mg/kg and in Group B inj. Propofol 1.5-2mg/kg. Then, Inj. Succinyl choline 0.5-1mg/kg was given. Patients were ventilated with 100% oxygen with bain circuit and mask. Shock was given after putting bite block. Patients were again ventilated till spontaneous respiration after seizures. Results: Propofol is better induction agent as compared to thiopentone sodium in terms of faster induction, better haemodynaemic stability, no significant effect on seizure duration, early recovery without any side effects. Conclusion: Propofol in the dosage of 1.5-2 mg/kg body weight intravenously can be safely used for modified ECT in ASA grade I and II pateints. Fast, smooth induction, better hemodynamics, early smooth recovery, antiemetic property and uncompromised therapeutic outcome makes propofol as an agent of choice for day care procedure. Though there is reduced seizure duration with Propofol as compared to thiopentone, there is no effect on outcome of the therapy or effectiveness of ECT.
