Neuromuscular blocking agents
From WikEM
Contents
Background
- Non-depolarizing
- Competitively block binding of ACh to its receptors
- Depolarizing
- Depolarizing skeletal muscle fiber
- Persistent depolarization makes the muscle fiber resistant to further stimulation by ACh
Types
Agent | Time to onset (seconds) | Duration (minutes) | Side effects |
---|---|---|---|
Non-Depolarizing | |||
Succinylcholine | fasciculations, post-operative pain | ||
Depolarizing | |||
Vecuronium (Norcuron) | 60 | 30–40 | Few, may cause prolonged paralysis and promote muscarinic block |
Rocuronium (Zemuron) | 75 | 45–70 | may promote muscarinic block |
Pancuronium (Pavulon) | 90 | 180 or more |
