Q

What do you want to be careful of when reversing drugs?

A

Reversing analgesic effects.

24
Q

Depressed thermoregulation under anesthesia can lead to what?

A

Hypothermia

25
What are 4 ways heat is lost?
- Evaporation - Radiation - Conduction - Convection
26
What are 3 classes of drugs that alter thermoregulation?
- Opioids - Alpha 2 agonists - Inhalants
27
Inhalants lower thermal threshold response to what temperature? What won't happen in the patient until this level is reached?
- 34.5 C | - Patient won't shiver.
28
How do you convert from Celsius to Fahrenheit?
Multiply by 1.8 and then add 32
29
A patients body temperature decreases over time with what? How much in dogs? How much in horses?
- Inhalants - 2 C/hr - 0.37 C/hr
30
Hypothermia (body temp
Reduces hepatic metabolism.
31
What effect does hypothermia have on the CNS?
Depresses CNS activity (cold narcosis)
32
What effect does hypothermia have on the solubility of anesthetic agents? What effect does this have on their DOA?
- Increased solubility | - Longer DOA
33
What are 3 options for treating hypothermia seen with prolonged recovery?
- Circulating warm water pads - Forced warm air device - Conductive fabric
34
What are 3 organs that may be affected by reduced cardiac output seen with prolonged emergence?
- Lungs - Kidney - Liver
35
How can prolonged emergence affect protein binding? | Why is this a problem?
- Decreased protein binding. | - Adequate amounts of protein are necessary to take drug to liver to be metabolized.
36
An altered acid base status of
Altered mental status
37
What are 4 effects renal failure and azotemia can have that cause prolonged emergence?
- Altered acid base status - Decreased protein binding - Delayed excretions of drugs & metabolites - Electrolyte changes
38
What are 7 examples of endocrine imbalances that can cause prolonged emergence?
- Hypothyroidism - Adrenal insufficiency - Sepsis - SIRS - Pancreatitis - Uremia - Hypoglycemia
39
What are 4 possible causes of hypoglycemia that can cause prolonged emergence?
- Neonates - Very small patients (increased metabolic rate) - Fasted diabetics treated with insulin - Glucocorticoid deficiency
40
What are 7 examples of neurological conditions that can lead to prolonged emergence?
- Hydrocephalus - Cerebral hypoperfusion - Hypoxia - Elevated ICP - Cerebral ischemia - Cerebral edema
41
Can genetic differences cause prolonged emergence?
Yes
42
Can idiosyncratic reactions cause prolonged emergence?
Yes
43
What commonly occurs within the first 10 minutes of emergence?
Postoperative delirium
44
How long can postoperative delirium last?
Up to an hour.
45
Hyperarousal, agitation and hyperactivity can be seen with what?
Postoperative delirium
46
What are 6 possible causes of postoperative delirium?
- Surgery - Infection - Anemia - Drugs - Hypotension - Hypoxia
47
What are 3 things can cause postoperative delirium?
- Decreased Acetylcholine - Increased Dopamine - Increased Cortisol
48
Postoperative delirium is common in what 3 breeds of dogs?
- Greyhounds - Russian Wolfhounds - Afghans
49
What are 3 possible treatments for postoperative delirium?
- Reversal agents - Quiet, dark, padded room/cage - Sedate
50
Wait to extubate and deflate the cuff until what happens?
Patient swallows or coughs.
51
What needs to be monitored during recovery?
Mucous membrane color and ventilation
52
The patient should be placed in what type of recumbency during recovery?
Sternal recumbency
53
What are 3 things that need to be maintained during recovery?
- CV support - Pulmonary support - Catheter patency
54
What is a concern with feline recovery?

55
What are 3 thing to keep available during equine recovery?
