4 routes of Anesthetic administration: |
1. inhalant
2. injectable
3. oral
4. topical |
|
|
Time of anesthetic administration (3) |
1. preanesthetic
2. induction
3. maintenance |
|
|
Principal Effects of Anesthesia:
8 types of agents |
1. local 2. general 3. sedatives 4. tranquilizers 5. analgesics 6. anticholinergic agents 7. reversal agents 8. neuromuscular blocks |
|
|
Anesthetic agents do what to the CNS? |
stimulate or depress |
|
|
What do agonists do? |
Bind to and stimulate target tissue |
|
|
What do antagonists do? |
Bind to target tissue, but DO NOT stimulate.
(they block the agonist so it can't get there) |
|
|
Most anesthetic agents are:
a) agonists b) antagonists |
AGONISTS |
|
|
Most reversal agents are: |
ANTAGONISTS |
|
|
Partial Agonists and Agonist-Antagonists
What are they use for?
Give an example (overall drug category) |
1. used for blocking agonists
2. opioids |
|
|
Analgesia:
1. what do they provide? 2. when are they used (3 times) 3. do they provide anesthesia?
|
1. pain control
2. pre-op, during, post-op
3. no - they do not provide anesthesia |
|
|
Do most general anesthetics provide analgesia? |
NO |
|
|
Analgesics must be provided at what times? |
pre-op and post-op |
|
|
Is there pain perception while anesthetized? |
NO |
|
|
Combining Drugs:
Can drugs be mixed in a single syringe? |
Only drugs that are compatible can be mixed in a single syringe. |
|
|
If you mix drugs and a precipitate develops, can you use the drugs? |
NO |
|
|
Most anesthetic agents and adjuncts are ___________ - ______________. |
Water soluble |
|
|
What commonly used drug is NOT water soluble?
What does this mean? |
Diazepam
it can never be mixed with any other drugs |
|
|
What do preanesethetic meds do?
6 things |
1. calm / sedate excited animal 2. minimize adverse drug effets 3. reduce dose of concurrent drugs 4. smoother anesthetic induction and recovery 5. provide analgesia 6. muscle relaxation |
|
|
When should pain meds be given? |
BEFORE we cause any pain |
|
|
Routes of Administrations: Premeds
(3)
onset / duration time for each |
SQ - slowest onset, longest duration
IM - faster onset, shorter duration
IV - fastest onset, shortest duration |
|
|
Preanesthetic Anticholinergics - what are they? |
Parasympatholytic drugs
They block acetylcholine
*They decrease effects of the parasympathetic nervous system stimulation (such as bradycardia and excessive salivation |
|
|
What do anticholinergics do?
|
1. prevent and treat bradycardia
2. decrease salivary secretions |
|
|
Give 2 examples of anticholinergics.
How can they be given? |
Atropine
Glycopyrrolate (dogs and cats)
IV, IM, SQ, IT |
