ABSTRACT:The aim of the study was to compare the seizure duration, haemodynamic changes and recovery characteristics following modified electro convulsive therapy (ECT) between propofol and thiopentone, used as anaesthetic agents. Forty patients who presented for a minimum of two ECT treatments consecutively were studied. Patients were randomly allocated to receive either 1 % propofol or 2.5 % thiopentone for their first treatment and the other drug was administered on the second occasion. All patients were preoxygenated for three minutes. Isolation of a limb was done in the upper limb at the level of the arm by using a blood pressure cuff that was inflated 50mmHg above systolic blood pressure. Anaesthesia was induced. Following the onset of anaesthetic effect, depolarizing muscle relaxant succinyl choline was administered intravenously. Muscle fasiculations or fine twitching movements monitored. The electrical stimulus was delivered by the attending psychiatrist using bifrontal electrodes. The duration of motor seizure in isolated limb was recorded. Thus concluding propofol is better induction agent than thiopentone sodium for modified electroconvulsive therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
