An autopsy case of malignant hyperthermia.
A report is made of a 44-year-old female who died of malignant hyperthermia during general anesthesia for an operation of left subtrochanteric femoral fracture. Symptoms began with increases in heart rate and blood pressure after the introduction of anesthesia with halothane and were accelerated by the administration of succinylcholine, followed by muscle rigidity and high temperature. The typical wine red urine was observed. The oral temperature of 42 degrees C was recorded within 1 h after succinylcholine. The rectal temperature was 30 degrees C 22 h after death. Severe pulmonary edema and tubular necrosis of the kidney were found by postmortem examination. No latent myopathy was observed. The creatine phosphokinase levels in plasma obtained after the onset of malignant hyperthermia and at the time of autopsy were abnormally high and were 5632 and 34,854 mU/ml, respectively. Plasma myoglobin levels were 130,000 and 2.8 X 10(6) ng/ml, respectively.
