How do I know if I have Malignant hyperthermia?

How to Determine if You Have Malignant Hyperthermia

Malignant hyperthermia (MH) is a rare but potentially life-threatening condition that can occur during or after general anesthesia. It is characterized by a severe reaction to certain medications used during surgery, leading to a rapid increase in body temperature, muscle rigidity, and other dangerous symptoms. If you suspect you may have MH or have a family history of the condition, it is crucial to be aware of the signs and take appropriate precautions.

1. Understand the risk factors: MH is often inherited, so having a family member with the condition increases your risk. Additionally, certain genetic mutations are associated with MH susceptibility. If you have a family history of MH or possess these genetic mutations, you may be at a higher risk of developing the condition.

2. Recognize the symptoms: MH typically manifests during or after exposure to triggering agents, such as certain anesthetic gases or muscle relaxants. The most common signs include:

• Unusually high body temperature: Your body temperature may rise rapidly, exceeding 104°F (40°C).


• Muscle rigidity: Your muscles may become extremely stiff, particularly in the jaw, neck, and chest.


• Rapid heart rate: Your heart may beat faster than usual.


• Increased breathing: You may experience rapid, shallow breathing.


• Dark-colored urine: Your urine may appear brown or red due to muscle breakdown.

3. Consult a healthcare professional: If you suspect you have MH or have experienced any of the aforementioned symptoms, it is crucial to seek immediate medical attention. Contact your healthcare provider or go to the nearest emergency room. Prompt diagnosis and treatment are essential to prevent complications and ensure your safety.

4. Undergo diagnostic testing: To confirm a diagnosis of MH, your healthcare provider may perform a muscle biopsy or genetic testing. These tests can identify specific abnormalities associated with MH susceptibility.

5. Inform your healthcare team: If you have a known history of MH or suspect you may be susceptible, it is vital to inform your healthcare providers before any surgical procedure. They can take appropriate precautions, such as using alternative medications or monitoring your vital signs more closely, to minimize the risk of an MH episode.

Remember, this information is not a substitute for professional medical advice. If you have concerns about MH or any other medical condition, consult a qualified healthcare professional for personalized guidance.
