Malignant hyperthermia syndrome

P M Waterman

    American Journal of Ophthalmology
    |October 1, 1981

    Summary
    This summary is machine-generated.

    Malignant hyperthermia is a rare pharmacogenetic disorder causing uncontrolled calcium release in muscles. Prompt treatment with oxygen, dantrolene, and fluids successfully managed a crisis in a pediatric patient, leading to full recovery.

    Area of Science:

    • Pharmacogenetics
    • Biochemistry
    • Critical Care Medicine

    Background:

    • Malignant hyperthermia is a life-threatening pharmacogenetic disorder.
    • It is characterized by uncontrolled calcium ion release into muscle cells.
    • This leads to hypermetabolism, acidosis, and heat production.

    Observation:

    • A 4-year-old girl experienced a malignant hyperthermia crisis during strabismus surgery.
    • The crisis presented with symptoms of severe metabolic and respiratory acidosis and heat generation.

    Findings:

    • The patient was treated with 100% oxygen, intravenous dantrolene sodium, furosemide, and fluid administration.
    • This therapeutic regimen effectively controlled the malignant hyperthermia attack.

    Implications:

    • Early recognition and aggressive management are crucial for malignant hyperthermia crises.
    • Successful treatment can lead to complete patient recovery.
    • This case highlights the importance of prompt intervention in pediatric pharmacogenetic emergencies.
