What is one of the symptoms of malignant hyperthermia?

Malignant hyperthermia is a serious reaction to certain anesthesia medications, leading to rapid increases in body temperature as well as muscle rigidity. Among the symptoms, skin mottling can occur as a result of altered blood flow and metabolic disturbances caused by the hypermetabolic state associated with the condition. As the body temperature rises dramatically, the skin may begin to show mottled patterns due to peripheral vasoconstriction and changes in oxygenation.

Cold extremities, hypotension, and decreased heart rate are not characteristic symptoms of malignant hyperthermia. Cold extremities might indicate shock or poor circulation, hypotension could result from various other medical conditions, and decreased heart rate does not align with the typical physiological response of a hypermetabolic state, which usually leads to an increased heart rate. Thus, skin mottling is more directly related to the pathology of malignant hyperthermia and is a noteworthy symptom indicating its severity.
