About Malignant Hyperthermia

Malignant Hyperthermia is a condition that can be triggered when genetically susceptible individuals come in contact with certain inhaled (volatile) anesthetics or the muscle relaxant succinylcholine. These patients can experience tachycardia, elevated blood pressure, raised carbon dioxide levels, and very high body temperature levels. If not treated immediately, the hypermetabolic episode can be fatal.
