Study Notes
Muscle Paralysis and Neuromuscular Blockers
- The sequence of muscle paralysis observed with depolarizing blockers is: small muscles (e.g., facial, finger), followed by larger muscles (e.g., arm, leg), and finally, the diaphragm and other respiratory muscles.
- Succinylcholine has a short duration of action, typically 4-6 minutes.
- Curare is a type of non-depolarizing (competitive) neuromuscular blocker.
- Pancuronium causes a increase in heart rate and blood pressure, as well as a decrease in gut motility and secretions.
- Competitive neuromuscular blockers, such as pancuronium, are clinically used to provide muscle relaxation during surgery, especially in conjunction with general anesthesia.
