27
Q

What type of drug is meloxicam?

A

NSAID, Cox-2 selective inhibitor

28
Q

How does meloxicam reach analgesic affects?

A

analgesia via decreased inflammation

29
Q

What is the rate of onset and duration of Meloxicam?

A

30-60 minute onset

duration 12-24 hours

30
Q

What side effects does Meloxicam cause?

A

GI upset/ulceration, renal toxicity possible

31
Q

What is the dosage for maropitant?

A

2 mg/kg PO

32
Q

What type of drug is maropitant?

A

antiemetic, NK-1 antagonist inhibiting substance p

33
Q

What is the rate of onset and duration of maropitant?

A

Onset in 30-60 minutes

duration is 24 hours

34
Q

What side effects are associated with maropitant?

A

hypersalivation, diarrhea, and anorexia possible

35
Q

With premedications, when will your patient usually reach a plane of general anesthesia?

A

in 3-10 minutes

36
Q

What must you do to the arytenoids in cats prior to intubation?

A

desensitize them with topical lidocaine and then wait 1 minute for the drug to work

37
Q

What will trauma to the trachea during intubation lead to?

A

spasm

38
Q

Once your cat has been intubated, what are the next steps?

A

Hook up your patient to circuit (non-rebreathing) and administer oxygen
Secure the tube, check the inflate cuff and have the pulse-ox attached

39
Q

When does the anesthesia sheet begin?

A

When the patient has been intubated

40
Q

If your patient is not fully anesthetized post-premedication, what should you do?

A

place an IV catheter to administer propofol (use 1/3 of the dose) and then intubate

41
Q

What is the preferred IV catheter size in cats?

A

22 gauge

42
Q

What is the preferred vein for catheterization? If that doesn’t work, what is the next step?

A

Cephalic vein is preferred, medial saphenous is the next best

43
Q

What is the limit of attempts of catheterization per leg?

A

2

44
Q

What is the inhalant of choice for anesthesia?

A

isoflurane

45
Q

What is the rate of onset for Isoflurane?

A

rapid onset and decline

46
Q

What is the primary concern for Isoflurane?

A

Vasodilation - more gas = lower BP

47
Q

What is the MAC in the cat and is it relevant?

A

MAC is 1.3%, not very relevant with heavy premed on board

48
Q

Typically, what is the % iso required during surgery?

A

0.5-1.5% with 2-3% in brief periods if the patient is light

49
Q

What should you do if there is excessive movement during surgery?

A

inject 1-2 mg/kg of propofol IV

50
Q

What instruments are used for monitoring patients during surgery?

A

Doppler, esophageal stethoscope, ECG, pulse-ox, and temperature probe

51
Q

What does the doppler measure?

A

systolic blood pressure

52
Q

What are the different components/equipment of the doppler?

A

Cuff and sphygmomanometer, probe with piezoelectric crystals and sound amplifier, and ultrasound gel

53
Q

What complications can happen during surgery?

A

laryngospasm, hypotension, hypothermia, bradycardia, hypersalivation, hypo/hyperventilation, aspiration, and violent recovery
