Core Concepts In Pharmacology Ch 12

Front 1

anesthesia

Back 1

medical procedure performed by applying drugs that cause loss of sensation

Front 2

local anesthesia

Back 2

AKA sodium channel blockers

loss of sensation to limited part of body w/o losing consciousness

blocks entry of sodium ions into cells of nervous system

Front 3

general anesthesia

Back 3

causes loss of sensation to entire body

usually results in loss of consciousness

Front 4

topical anesthesia

Back 4

AKA surface anesthesia

creates loss of sensation on mucous membranes

Front 5

infiltration anesthesia

Back 5

AKA field-block anesthesia

drug diffuses into tissue into tissue to block specific group of nerves in small area

Front 6

nerve block anesthesia

Back 6

affects bundle of nerves serving area to be operated upon

used to block sensation in limb or large are of face

Front 7

spinal anesthesia

Back 7

affects large area (ie lower abdomen & legs)

drug injected into cerebral spinal fluid

Front 8

epidural anesthesia

Back 8

regional anesthesia commonly used in obstetrics

drug injected into epidural space of spinal cord

Front 9

esters

Back 9

type of chemical linkage found in some local anesthetics involving carbon & oxygen

first to be used for local anesthesia

Front 10

amides

Back 10

type of chemical linkage found in some local anesthetics involving carbon, nitrogen, & oxygen

replaced esters due to longer duration & fewer side effects
