Malignant Hyperthermia

Richard D. Urman

DefinitionMalignant Hyperthermia (MH) is an inherited disorder of skeletal muscle, which is characterized by a hypermetabolic state and can be triggered by potent volatile anesthetics (but not nitrous oxide) and depolarizing muscle relaxants such as succinylcholine. Patients with some congenital myopathies may also be at increased risk when exposed to triggering anesthetic agents. However, all intravenous hypnotic agents are considered safe. MH is a potentially fatal disorder if it is not promptly recognized and treated, and the overall incidence during general anesthesia is about 1:50,000–1:100,000. For any patient presenting for anesthesia, a preoperative history should include questions about prior MH episodes or family history suggestive of MH.

MechanismIn a vast majority of cases, MH-susceptible patients have a defective calcium channel (known as ryanodine receptor) that is located on the sarcoplasmic reticulum membrane. In normal cells, calcium is released into the cell during muscle contraction. In MH, there is a problem with calcium reuptake, and therefore there is a massive increase in intracellular calcium leading to sustained muscle contractions. Consequently, there is an increased demand for oxygen and ATP in the muscle cells, leading to glycolysis and lactic acidosis. If left untreated, this uncontrolled hypermetabolism results in cell hypoxia, rhabdomyolysis, organ failure, and death.

Presenting Signs and DiagnosisThe most common presenting features of MH include significant, unexplained elevation in expired CO2, tachycardia, steady temperature rise, muscle rigidity, rhabdomyolysis, acidosis, and hyperkalemia. MH may occur at any time during anesthesia and in the postoperative period. The earliest signs are usually tachycardia and an increase in expired CO2; a rise in temperature may follow. Diagnosis of MH can be made on the basis of these signs, although the variability in the order and time of the onset of signs often makes clinical diagnosis difficult. These signs may present during or after the administration of the anesthetic. Table B.1 outlines possible presenting signs of MH.

Diagnosis is made based on the presenting signs, and other potential condi-tions that might cause the same symptoms should be ruled out. Genetic testing is also available, which can be done on an outpatient basis at an MH Testing Center. If MH is suspected, treatment should be initiated as soon as possible.

TreatmentAll triggering agents should be discontinued immediately, the surgical procedure should either be aborted or finished quickly, and patient cooling begun. Dant-rolene, a muscle relaxant which abolishes excitation–contraction coupling in muscle cells, is the main drug of choice. Important treatment modalities for MH are outlined in Table B.2.

Over the last several decades, thanks to provider education and increased knowledge about MH, perioperative patient mortality from MH has dropped from 80% to less than 5%. An MH-susceptible patient is still a candidate for any type of anesthetic, including general, regional, or local. If general anesthetic is

Table B.2 Treatment of acute malignant hyperthermia.

1. Discontinue volatile agents and succinylcholine

2. Call for help

3. Hyperventilate with 100% oxygen

4. Inform the surgeon and curtail the surgical procedure

5. Initiate treatment with dantrolene (2.5 mg/kg)

6. Administer bicarbonate for metabolic acidosis

7. Actively cool the patient

8. Treat acidosis and hyperkalemia to avoid arrhythmias

9. Follow ETCO2, electrolytes, blood gasses, CK, temperature, and urine output
