Postoperative malignant hyperthermia: an analysis of cases from the North American Malignant Hyperthermia Registry.

Background: The initial presentation of malignant hyperthermia (MH) may begin in the postoperative period. However, the maximal latency period between the end of anesthesia care and the onset of postoperative MH is unknown. The authors hypothesized that this latency period is short and is not manifested by hyperthermia as the initial presenting sign.
