Patients with occult or known myopathies such as CCD,
MmD, DMD, or BMD may have a higher risk for an MH or MH-like episode upon exposure to a triggering anesthetic agent. Such patients should be evaluated by a neurologist prior to providing treatment
and/or diagnostic testing
recommendations.
ŘCCD, MmD associated with MH susceptibility.
ŘPatients with Duchenne’s or Becker’s muscular
dystrophies are at risk for
hyperkalemic cardiac arrest with succinylcholine or other MH triggering agents (but this is NOT MH).
ŘIndividuals with any form of myotonia should not receive
succinylcholine.
