- Succinylcholine
- Mechanism
- Depolarizing Neuromuscular Blocker
- Blocks repolarization of the muscle cells, preventing them from contracting
- Depolarizing Neuromuscular Blocker
- Clinical Use
- Muscle relaxant/paralytic
- Used as an adjunct in anesthesia to paralyze the muscles of the oropharynx during intubation to prevent gag reflex and aspiration
- Control seizures during electroconvulsive therapy (ECT)
- Muscle relaxant/paralytic
- Side Effects and Adverse Reactions
- Malignant hyperthermia
- Medical emergency; excessive release of calcium in muscles causes sustained muscle contractions
- Characterized by high fever, muscle rigidity
- Respiratory depression
- Bradycardia
