20
Q

What is the patient prep for a gastroscope? - SA

21
Q

And what is the prep for equine?

A
  • Starve them and remove water.

- Sedate them unless looking for laryngeal paralysis.

22
Q

what is the patient prep for arthroscopy?

A
  • Same as above but for equine, clip/clean and wash are before taking them to anaesthetics (doing this before GA reduces anaesthetic time).
  • Remove hair etc.
23
Q

What would you do to prepare for a colonoscopy?

A
  • Give an enema/laxative before.

- Client compliance - Are they going to give this themselves before coming to practice?

    - False sense of security - can still kick through them.
    - Horse can panic and they can be quite claustrophobic so small spaces aren’t ideal and can cause self trauma.
