Study Notes
Malignant Hyperthermia
- Malignant hyperthermia is a life-threatening reaction to certain anesthetic agents (gases and succinylcholine).
- Excessive muscle contractions, heat production, and elevated CO2 and heart rate occur.
Skeletal Muscle Contraction
- Calcium (Ca++) is crucial for muscle contraction.
- It is stored in the sarcoplasmic reticulum (SR).
- Sodium (Na+) initiates the process, leading to the release of Ca++.
- Adenosine Triphosphate (ATP) provides energy for the process.
