Answer: c) MethohexitalMethohexital has minimum interference with therapeutic induction of seizures. Hence, it is the drug of choice for electroconvulsive therapy (ECT).Propofol can be used as an alternative if methohexital is contraindicated.Therapeutic seizures induced by ECT typically last for 15-70s.The steps involved in the anesthesia for ECT are as follows:Pre-oxygenation: Should be maintained at near 100%. It decreases post-seizure hyperventilation and prevents increased intensity of seizures.Anesthetic medication: Drug of choice is methohexital.Anticholinergic medication: It prevents vagally mediated bradycardia and reduces excess respiratory and oral secretions.Skeletal muscle relaxant: It prevents musculoskeletal injury.
