MH presentation can vary depending on the triggering agents and environmental factors, such as metabolic state and body temperature, at the beginning of anesthesia. Without proper and prompt treatment with dantrolene, mortality is extremely high, up to 80%. Even with treatment and survival, the individual is at risk for life-threatening consequences and recurrence of the syndrome within the first 24-36 hours following an episode.  A study of the North American MH registry showed that nonfatal complications occurred in 35% of affected cases reported from 1987 to 2006. Complications included cardiac, renal, or hepatic dysfunction; coma or change in consciousness; pulmonary edema; and disseminated intravascular coagulation. A significant male preponderance has been reported. All ethnicities are affected.",

Most report an incidence of about 1/10,000 anesthetics in children and 1/50,000 in adults. MHS has an estimated prevalence of 1/60,000-1/100,000. The prevalence of MH in individuals undergoing surgery in New York state hospitals was estimated as 1/100,000 for adults and 3/100,000 children. However, as many individuals undergoing surgery who experience marked hyperthermia may be coded as being MH susceptible, the exact incidence and prevalence has been difficult to clarify. It seems certain that there are more than 1,000 cases of MH in the US each year.",

An MH episode may begin with hypercapnia, rapidly rising end-tidal CO2, and tachycardia followed by hyperthermia. Additional symptoms may include acidosis, muscle rigidity, compartment syndrome, rhabdomyolysis and subsequent increased creatine kinase, hyperkalemia with a risk for cardiac arrhythmia or even arrest, and myoglobinuria with a risk for renal failure.  \n\nThere is mounting evidence that some individuals with MHS may also develop episodes triggered by non-anesthetic conditions such as heat and/or exercise. These non-anesthetic-induced episodes, often called MH-like syndrome, may manifest as exertional rhabdomyolysis (ER). Clinical features are similar to MH and include muscle cramps, elevated temperature, tachycardia, tachypnea, hyperkalemia, and elevated levels of serum myoglobin and creatine kinase. Reports of heat and exercise-induced MH-like reactions in patients with MHS and patients with ER who test positive for MH support an association, though more evidence is needed.",
