Malignant hyperthermia in a child with sleep apnea

: Malignant hyperthermia is a syndrome characterized by a hypermetabolic state of skeletal muscle (1, 2). It is transmitted by genetic inheritance. The syndrome has frequently been associated with certain neuromuscular and other disorders (1, 3). A case of the syndrome occurring in a child with sleep apnea syndrome, an association not previously reported, is discussed here.
