This case suggests that spinal anesthesia, even with an ordinary dose of hyperbaric 0.5% bupivacaine, might induce cauda equina syndrome in older patients.

We report the successful anesthetic management of a patient with Brugada syndrome who underwent electroconvulsive therapy to treat bipolar disorder. Suxamethonium and neostigmine were contraindicated to avoid the vagotonic effects that can precipitate ventricular fibrillation during anesthesia in patients with Brugada syndrome. The combination of 1.2 mg/kg rocuronium and 10 mg/kg sugammadex was effectively and safely used to induce and antagonize neuromuscular block for 8 consecutive electroconvulsive therapy sessions in this patient.

The time to reach a TOF ratio of 0.9 following sugammadex is dependent on CO in elderly patients.

The times from rocuronium injection to reappearance of the first response to PTC stimulation are approximately twofold longer and more variable in older than younger patients. Hence, the dosing interval of rocuronium should be adjusted using neuromuscular monitoring when maintaining intense neuromuscular block, especially in older patients.
