Unit 1 - Anesthesia Intro Flashcards
1
Q
General description of anesthesia
A
- Loss of feeling or sensation (including pain)
- Intentional
- Reversible
- Local, regional, general
2
Q
Local anesthesia
A
- loss of feeling or sensation to a specific area due to local desensitization
- freezing / line blocks
3
Q
Regional anesthesia
A
- loss of feeling or sensation to a large part of the body (limb, abdomen)
- due to desensitization of SPINAL NERVES and/or PERIPHERAL NERVE BUNDLES
- spinal block, epidural
4
Q
General anesthesia
A
- anesthetics due to depression of the CNS
- affects entire body
- “coma-like state”
- patient neither perceives nor recalls noxious stimuli
- increased risk for adverse effects
5
Q
Tranquilization
A
- reduces anxiety and produces sense of tranquility
- “antianxiety” “calm”
- reduces ability to respond to stimuli
- no change in ability to perceive pain
6
Q
Sedation
A
- more profound than tranquilization and produces drowsiness and/or hypnosis
- reduce anxiety, reduce ability to respond to stimuli
- decrease pain sensation
- animal is conscious
- 3 levels
7
Q
1st level of sedation
A
light sedation
8
Q
2nd level of sedation
A
- moderate sedation
9
Q
3rd level of sedation
A
- heavy sedation
10
Q
Hypnosis, Narcosis
A
- greater degree of CNS depression
- consciousness affected (entering unconscious state)
- overlaps with stage 1 and 2 of GA
11
Q
Surgical anesthesia
A
- patient unconscious
- no pain perception
- significant CNS depression
12
Q
Analgesia
A
- relief of pain without loss of consciousness
13
Q
Analgesic
A
- a drug that relieves pain
14
Q
Multimodal anesthesia/analgesia
A
balanced anesthesia
15
Q
Balanced anesthesia
A
- using multiple drugs in a combination
- in smaller doses than if only using 1 drug
- obtain appropriate CNS depression to perform a specific procedure
