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
16
Q
Balanced anesthesia includes
A
- pre-med
- induction agent
- maintenance anesthetic
- analgesics (pre and intra operative)
17
Q
Benefits of balanced anesthesia
A
- limits adverse effects of each drug
- maximizes the benefits of each drug
- accounts for motor, sensory (PAIN), reflex and mental aspects of NS
18
Q
Balances anesthesia protocol must take into account:
A
- the patient
- procedure
- facilities available
19
Q
True or false: your anesthetic protocol changes between every patient
A
- true
- sometimes for the same patient
20
Q
RVT’s role
A
- prep, operation, and maintenance of anesthetic equipment
- administration of anesthetic agents
- endotracheal intubation
- patient monitoring
- planning
21
Q
RVT’s role: patient assessment
A
- weight
- TPR
- assess pre-procedure mentation and pain
- any preanesthetic diagnostics (blood, rads)
22
Q
RVT’s role: premed
A
- calculate dosages, administering medication
- assessing degree of sedation after administration
- responding to adverse reactions to sedation/premed
23
Q
RVT’s role: surgical fluids
A
- setting up fluids
- catheter placement
- calculating fluid rates based on fluid plan
24
Q
RVT’s role: induction
A
- calculating and administering anesthetic dose
- endotracheal intubation
- assessing anesthetic depth
- patient monitoring
25
Q
A
