Why not use “non-triggering” agents for all patients?
The so-called triggering agents are used in thousands of patients every day, and they are generally very safe with the exception of the rare patient with susceptibility to MH. Therefore it would not be practical to avoid these agents in all patients, regardless, since an MH-crisis is such a rare occurrence in the operating room (as rare as 1 out of 50,000 anesthetics) Also, under certain circumstances many anesthesiologists may prefer using one of the triggering agents provided the patient is not MH-susceptible.
