Ave the weakest possible in triggering an acute MH crisis. The information show that practically all confirmed MH episodes were triggered by a mixture of volatile anesthetics and SCh (81 ) or volatile anesthetics only (18 ). Notably the SCh only case within this study happened to a patient who showed all patient associated threat factors: he was male, young (12 years old) and carried the causative RyR1 mutation p.R614C positioned inside MH/CCD region 2. He developed a CGS of 15 points, which represents a much less severe event. An anesthetist needs to be conscious of feasible MH reactions to SCh in clinical practice and furthermore need to understand that the combination of volatile anesthetics and SCh in specific is unsafe in predisposed individualspeting interests The authors declare that they have no competing interests.Klingler et al.
