1

What is the recovery period?

Period between disconnection of anaesthetic administration to the time whent he animal can maintain unsupported recumbency

2

Why is the role of monitoring recovery important?

- 60% of anaesthetic mortality occurs during recovery
- Often neglected time of anaesthesia
- Other staff may be dealing with next patient
- Patient is still under your care

3

What does the duration of recovery depend on? Name 3

- Length of anaesthesia
- Condition of patient
- Age of patient
- Type of anaesthesia and route of admin
- Patients body temp

4

What are the 4 main stages of recovery?

- HR increase
- RR increases and volume increases
- Eye position rotates centrally
- Reflexes become stronger e.g. palpebral, pedal, earf flick

5

What should you give your patient before disconnecting them from the anaesthetic machine? And what benefit is there to us

Pure oxygen
Benefit: Reduces pollution of volatile agent

6

When do you remove the ET tube from a patient?

- When the patient regains the swallow reflex

7

What patients do you remove the ET tube earlier in and why?

Cats due to potential laryngospasm

8

Do you wait longer or remove the ET quicker in brachycephalics

Wait longer

9

What position should the patient be in when removing the ET tube?

Lateral or sternal recumbency with neck extended

10

When removing an ET tube from the cat what should you also do?

Ensure cats tongue is at least partially out

11

What must you remember to do before removing the ET tube?

- Check for reflex
- Untie mouth tape
- Deflate cuff

12

What reflex do you look for in cats when wanting to remove the ET tube?

Ear flick

13

How are anaesthetics eliminated (injectables, and inhalationals)

- Injectables - liver metabolises and excreted by kidney
- Inhalational - respiratory tract

14

What can you give to speed up recovery?

Analeptics (reversal drugs)

15

Name 2 things that affect pain in the recovery period?

- Surgical procedure
- Perioperative analgesics used
- Surgical technique

16

Name 2 reasons why prolonged recovery may occur?

- Severe pain
- Persistent drug activity
- Hypothermia
- Too much or too little pain relief

17

What can we do to ensure prolonged recovery does not occur?

- Adequate analgesia
- Keep animal warm
- Reverse the effects of drugs if possible

18

Name the antagonist to opioids

Naloxone

19

Name the antagonist to alpha-2-agonists

atipamezole

20

Name the antagonists to benzodiazepines

flumazenil

21

Name 2 common recovery problems

- Excitation (stormy recovery)
- Hypoxia

22

What is a sign of excitation (stormy recovery)

- Pain
- Convulsions / epilepsy post myelography or in epileptic patients

23

What would you do to monitor potential hypoxia in brachycephalics

Keep a pulse oximeter on the patient
Remain with it and ensure they are well ventilated
Provide oxygen

24

Name 1 method you could use if the patient is hypoxic?

- Mask
- Intranasal catheter
- Tracheostomy tube
- Oxygen tent

25

How often should you turn a patient that is unable to maintain sternal recumbency and why

- every 2 hours
- Reduce the risk of hypostatic congestion

26

What can cause hypothermia in a patient during recovery

- anaesthetic used
- Prolonged procedure

27

How do combat / prevent hypothermia

- Keep warm from pre-med onwards
- Supplementary heating e.g. heat pads and blankets
- Monitor patients temperature regularly
- Efficient and quick procedure as possible

28

What should you ensure you do prior to the patient leaving the surgery

- Ensure patient has fully recovered from anaesthesia
- Clean patient up as much as possible before returning to owner
- Ensure they are leaving with analgesics if necessary
- Advise owner on any post-op complications that may occur and what is 'normal'
- Ensure owner understands all information and provide contact details

29

name the main things to do during post-operative monitoring

- Check vital signs
- Maintain observations
- Oxygenate
- Avoid hypothermia
- Manage pain
- Reverse drugs if necessary
- Turn recumbent patients
- Monitor wounds
