Injectable Anesthetics Flashcards
1
Q
Epidural Injection Complications
A
- Systemic infection
- Clotting issues
- Infected skin
2
Q
Local Anesthetics
A
- Impare nerve impluses in peripheral nerve
- No IV*
* can cause cardiac arrest or convulsions
3
Q
Telazol Routes
A
IV or IM
* rapid onset
4
Q
Alfaxalone
A
- Neuroactive steriod
- Anesthesia due to effect on GABA
- Inhibits neural impulse transmission
5
Q
Epidural Anesthesia
A
- Uses local anesthetic (lidocaine)
- Can give opioid same way for analgesia
- Effects caudal portion of body
6
Q
Lidocaine
Duration
A
- Short duration
- Rapid onset (30 sec)
7
Q
Lidocaine
with Epinephrine
A
- Slow absorption
- Increased length of action
- Increased risk of cardiac arrhythmias
8
Q
Cyclohexamine Characteristics
A
- Dissociative agent
- Antagonistic effects at NMDA receptor
- Catalepsy
- Analgesic - best when combined with opioid
9
Q
Cyclohexamine and CNS
A
- Does not depress
- May increase HR and BP
- Excitement during recovery
10
Q
Alfaxalone Route and Administration
A
- IV - no irritation if given outside vein
- Can give to sighthounds
- Rapidly eliminated
11
Q
Ketamine Effects
A
- Open, dilated eyes
- Salivation, no vomit
- Minimal respiratory depression
- Increased BP and cardiac output
12
Q
Telazol Effects
A
- High doses cause excitement and inspiratory apnea leading to hypoxia
- Good for aggressive patients
- Analgesia better than ketamine
13
Q
Propofol Effects
A
- CNS depression
- Bradycardia, decreased cardiac output, hypotension
- Respiratory depression
- Muscle twitching
14
Q
Cetacaine
A
- Topical use
- Apply to larynx to relax muscle during intubation
- Associated with Heinz body anemia
15
Q
Proparacaine
A
- Used for cornea
