As soon as malignant hyperthermia is suspected, doctors must act rapidly to treat the condition and prevent complications.
The first and most important step is to immediately stop giving the triggering medication and to stop the surgery. Doctors then give the drug dantrolene (Dantrium).
Dantrolene relaxes the muscles. It stops the dangerous increase in muscle metabolism.
Dantrolene is given intravenously until a patient has stabilized. Then, the medication typically is continued in pill form for three days.
Additional treatment can include:
Lowering body temperature with:
Cool mist and fans
Cooled intravenous fluids
Using medications to:
Control the heartbeat
Stabilize blood pressure
Monitoring in an intensive care unit
