ABSTRACT
Malignant hyperthermia is an autosomal dominant syndromic disease,
associated with the rianodine gene mutation, secondary to an idiosyncratic
reaction to the exposure of anesthetic drugs such as neuromuscular
blockers and halogenated agents. There is a predisposition for male sex at
all ages. The pathophysiology is based on a movement of calcium ions from
the sarcoplasmic reticulum to the cytosol, which produces a persistent
contraction in the muscle cell, anaerobic metabolism, loss of homeostasis
and cell death. Sinus tachycardia, masseter muscle spasm, mixed acidosis,
tachypnea, hypercarbia and arrhythmias are early clinical signs. The
diagnosis is based on the halothane-caffeine contracture test, genetic tests
and the Bandschapp clinical suspicion scale. dantrolene is considered the
pharmacological pillar for the treatment of this pathology.
