Comparison between succinylcholine and rocuronium as neuromuscular blocking agents for electroconvulsive therapy in a patient with pseudocholinesterase deficiency.

We report here the anesthetic management of a patient with schizophrenia and pseudocholinesterase deficiency. Electroconvulsive therapy was performed using succinylcholine and rocuronium as the neuromuscular blocking agents in the first seven and latter six treatments, respectively. The recovery time from muscle relaxation after succinylcholine administration was remarkably longer than that after rocuronium-sugammadex administration. Rocuronium and sugammadex appear to be useful in situations in which succinylcholine is contraindicated.
