Malignant hyperthermia in a patient receiving nitrous oxide.
Summary
Malignant hyperthermia can be triggered by nitrous oxide anesthesia, even with dantrolene premedication. Successful management was achieved using dantrolene alone, avoiding nitrous oxide in a subsequent anesthetic event.
Area of Science:
- Anesthesiology
- Pharmacology
Background:
- Malignant hyperthermia (MH) is a severe, unpredictable pharmacogenetic disorder of skeletal muscle.
- Nitrous oxide is generally considered a safe anesthetic agent, but its interaction with MH susceptibility requires careful consideration.
