[Prolonged effects of vecuronium in a patient with Crow-Fukase syndrome].

We gave anesthesia to a patient with the Crow-Fukase syndrome. A patient with this syndrome shows polyneuropathy, endocrinological symptoms, skin change, hypertrichosis, organomegaly and osteosclerotic change. We monitored the effects of vecuronium using a neuromuscular blockade monitor. The patient with this syndrome was hypersensitive to vecuronium and its effects lasted longer than usual. It is important to monitor neuromuscular blockade carefully in patients with this syndrome.
