Study Notes
Regional Anesthesia
- Regional anesthesia involves injecting an anesthetic drug around a nerve trunk to block nerve impulses.
- This prevents sensation from the region supplied by the nerve.
- Also called nerve block.
- The anesthetic drug is injected around a main nerve trunk supplying an area, preventing impulse conduction from that area through its nerve supply, thus eliminating sensation.
Experimental Setup
- Animal: Frog
- Drug: Amethocaine
- Route of Administration: Around the sciatic nerve plexus
- Experiment Goal: Determine if an unknown drug has nerve-blocking anesthetic properties similar to amethocaine.
- The unknown drug has nerve-blocking anesthetic effects similar to amethocaine, or has no effect.
