What is the proposed mechanism for malignant hyperthermia?
What is the proposed mechanism for malignant hyperthermia?
- Exposure to halogenated anesthetic agents leads to increased muscle relaxation due to increased release of Ca2+ from skeletal muscle sarcoplasmic reticulum, increased ATP production, decreased O2 consumption, CO2 production, and heat, resulting in membrane failure and leakage of K+, creatinine kinase, and myoglobin.
- Exposure to halogenated anesthetic agents leads to decreased muscle contraction due to release of Ca2+ from skeletal muscle sarcoplasmic reticulum, depletion of ATP, decreased O2 consumption, CO2 production, and heat, resulting in membrane failure and leakage of K+, creatinine kinase, and myoglobin.
