Flashcards in Post-anesthetic Period Deck (19):
1

Prevent hypothermia

bear huggers. Heating pads can burn

2

Put _____ on horse hooves to help traction when they wake up

elasticon

3

What to do when anesthetizing camellids?

keep head above body
keep intubated until they chew tube

4

Procedure for waking from anesthesia?

1. turn off inhalant
2. if normothermic, inc. oxygen flow will help them wake faster
3. take off fluids unless there's a reason to keep
4. keep attached to breathing circuit until spontaneous respiration
5. disconnect end tidal CO2 monitor form breathing circuit
6. when patient swallows, deflate cuff and extubate

5

What do we do differently with horses regarding inhalant concentration?

titrate down during surgery as much as possible

6

how do we combat nasal edema in horses (obligate nasal breathers)

phenylephrine solution in the nose

7

When to extubate horses?

doctor preference
1. tape it in place while they stand up
2. extubate before hand as long as phenylephrine has been in the nose for at least 15 minutes
3. extubate but add a naso-tracheal tube for recovery (less likely to kink)

8

After horse is breathing spontaneously?

give sedative (romifidine or xylazine) smooths the transition

9

look for ______ after surgery (horses)

horizontal nystagmus, like vertigo, dangerous to stand up with one

10

Once theyre standing check for

bilateral nasal flow

11

Apnea after you've extubated?

re-intubate, ventilate, discontinue any drugs (naloxone can treat narcotic OD)

12

airway obstructed after you've extubated?

re-intubate, ventilate, use suction, if all fails evaluate for tracheal collapse and treat medically (B agonist steroid or butyrol)

13

Last resort is

Tracheotomy

14

pleural space disease?
pulmonary edema?

thoracocentesis
furosemide, steroids, oxygen

15

hypothermia

<98 F
prolongs recovery and increases oxygen demand, increases clotting time

16

Risk of regurgitation (gastroesophageal reflux)

- alpha 2 adrenergic agonists and opioids both slow GI motility
- prokinetics (metachlopramide) or histamine blockers (decrease gastric acidity) can be used
- keep ET tube in and suction the pharynx until clear

17

Delayed return of consciousness?

1. perform PE
2. check bloodwork (hypoglycemia in puppies!)
3. give fluids
4. oxygen supplementation
5. reverse alpha 2s, benzodiazepines, opioids
6. flip patient, heat

18

emergence dysphoria

harsh vocalization after extubating, hard to differentiate with pain, can give opioid bolus to r/o pain

19

horses can get ______ after surgery.
tx?

Radial nervopathy
- splint leg, give banamine, takes time
usually euthanize if they cant stand post-surgery
