[Three times of anesthetic management in a patient with myotonic dystrophy].

A 38-year-old female, at 38-week gestation, was scheduled for cesarean section under epidural anesthesia. After the delivery, it was found that she had been diagnosed as myotonic dystrophy by the other physician and the neonate was a floppy infant indicating hereditary neuromuscular diseases. In her case, myotonic dystrophy had not been advanced and symptoms had been mild.
