New Guidance Focused on Genetic Testing for Malignant Hyperthermia, a Potentially Fatal Anesthesia Reaction

Guided by a few simple screening questions, genetic testing can play a key role in identifying patients at risk of malignant hyperthermia (MH): a rare, potentially life-threatening reaction to inhaled anesthetics. An expert panel outlines an updated approach to assessing MH risk in North American patients, according to a special article in the April 2026 issue of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA). The article is being co-published in the Canadian Journal of Anesthesia/Journal canadien d'anesthesie.
