My children are 4 generations removed from fatal malignant hyperthermia reaction, should I get them medic alert bracelets?
I would not. I would only include it as pertinent hx if undergoing general anesthesia and again state 4 generations ago. I do not think the anesthesiologist would do anything different but be more vogilent and refresh their protocols.
