The general advice for MH susceptibles is to be prudent in their exposure to excessive heat and exercise in hot environments. The same advice should be given to patients who are not MH susceptible. There is no contraindication to blood or organ donation by an MHS person. The safest approach is for an MHS child to wear a identification bracelet. In an emergency situation the parent might not be available and the child might not be able to provide the necessary information to medical personnel.
Malignant hyperthermia is inherited in humans in a pattern termed autosomal dominant.
The risk of MH susceptibility diminishes further out on the family tree, proportional to the dilution of the relationship. The only way to determine for certain the susceptibility status would be muscle biopsy testing. Hence when an acute MH episode occurs in a family member, all family members, including cousins, should be alerted to their potential risk as well. The purpose of the Registry is to collect specific information regarding an MH episode and to analyze data from such episodes in order to better understand the patterns of manifestation of malignant hyperthermia and to provide information to family members as to the susceptibility status of relatives when known.
