Malignant Hyperthermia

Malignant hyperthermia is a rare, inherited reaction that can be triggered by exposure to certain agents used during anesthesia and that causes a rapid and dangerous rise in body temperature.

Warning signs: Among its manifestations are muscle rigidity, a rapidly rising temperature, a fast heart rate, and metabolic disturbances.

Common causes: There is a genetic predisposition that makes the person sensitive to certain anesthetic medications.

Which specialist treats it? The anesthesiologist is key in recognizing and managing it during a procedure, and the internist can support the evaluation. If there is a family history of reactions to anesthesia, mentioning it to a professional before any procedure is a sensible measure.
