Malignant hyperthermia (MH) is a genetic disorder causing a dangerous reaction during anesthesia. This guide helps community surgeons diagnose and manage MH crises and care for susceptible patients.

Area of Science:

  • Anesthesiology
  • Genetics
  • General Surgery

Background:

  • Malignant hyperthermia (MH) is a rare, inherited muscle disorder.
  • MH crises can be triggered by specific anesthetic agents.
  • Symptoms include fever, muscle rigidity, and rapid heart rate, mimicking surgical emergencies.

Purpose of the Study:

  • To provide a community general surgeon's perspective on diagnosing and managing MH crises.
  • To review the care of MH-susceptible patients in both elective and emergent surgical settings.
  • To address the historical reluctance of community hospitals in managing MH-susceptible patients.

Main Methods:

  • Review of clinical presentation and diagnostic criteria for MH.
  • Discussion of anesthetic management strategies for MH-susceptible individuals.

  • Surgical considerations for patients with a history of MH.

    • Main Results:

    • Overlap in symptoms between MH crises and abdominal emergencies can complicate diagnosis.
    • Proactive management strategies are crucial for MH-susceptible patients.
    • Community surgeons can safely manage MH-susceptible patients with appropriate knowledge.

    Conclusions:

    • Early recognition and prompt management are vital for MH crises.
    • Improved understanding and protocols can alleviate challenges for MH-susceptible patients and their families.
    • Community surgeons play a key role in the perioperative care of MH-susceptible individuals.
