Q

2 Mechanism of Action of Anesthetic Agents:

A

A. Specific receptor theory

B. Membrane expansion theory

19
Q

theory that Blocks nerve conduction by decreasing the permeability of nerve cell membrane to Na+ ions by blocking the openings of the Na+ channels thus interferes with the depolarization process.

A

Specific receptor theory

20
Q

theory in which In uncharged or unionized form, the anesthetic agent is absorbed at the cell membrane and becomes part of cell membrane structure at the Na+ channel which altering the channel configuration.

A

Membrane expansion theory

21
Q

Q

Ocular side effects of topical anesthetics:

A
  1. Mild stinging & burning sensation - most common
  2. Conjunctival Vasodilation - red eyes
