Perioperative management of malignant hyperthermia during general anesthesia: A report of two cases.

We present two seemingly typical cases of intraoperative MH development, with details on perioperative assessment and rescue. Postoperative genetic test showed mutations in the ryanodine receptor type 1 gene.
