Intraoperative monitoring of the recurrent laryngeal nerve (RLN) during surgical dissection allows for real time identification and assessment of nerve function integrity. Since neuromuscular blockade interferes with electromyography, long-acting muscle relaxants cannot be used during anesthesia. We report a patient in whom monitoring of the RLN was unsuccessful because of prolonged muscle paralysis following the administration of succinylcholine, presumably due to a pseudocho-linesterase deficiency.
