Assuming it doesn't mean parenteral nutrition (misread on my behalf), it probably means parenteral desoxycorticosterne pivalate administration for postoperative support. Minimizing stressors such as hypoxemia, acidosis, hypothermia and hypotension during surgery can help reduce the stress response and multimidal analgesia can help reduce nociceptive stimuli which decreases the stress response.

General anaesthesia and surgery elicits a considerable "stress" response physiologically, patients receiving corticosteriods may have reduced adrenal cortex functon and require glucocorticosteroid supplementation to prevent all kinds of physiological disturbences and "post operative collapse" - parenteral is referring to the route of adminstration and has nothing to do with parenteral nutrition!

Read up on stress response to anaesthesia and surgery - quick google should put you in the right direction.

And, you probably know this, but do not use NSAID's if the patient is on corticosteroids due to GI ulceration (increase acid secretion and decrease mucus production). Agree with what Smegs friend says. CC's can cause impaired wound healing by inhibiting fibroblasts which produce scar tissue, along with delayed recovery from infection. Also take into account whatever reason the patient is on cc's, as whatever that is would potential affect/compromise the GA. Do they stipulate in the book what surgery it is in relation to? Recommending parenteral nutrition seems a bit extreme, what with all the risks and complications that brings with it.

I guess if you are explaining as you go, if you are doing a prac, I would rattle off all of that

just had a call from my friend- i think what your book is referring to is that corticosteroids have a thickening action on the blood, so IVFT is very important. Otherwise there is nothing more than normal to worry about anaesthesia wise. the main concerns with corticosteroids is infection and wound breakdown due to the immune system being compromised. She also advised that any animal on corticosteroids should be tested for Cushings prior to surgery, which can be caused by long term corticosteroid use, as the liver is then compromised.

Hope that helps

I'm looking it up now, i think I have the same book as your notes. Not helpful in explanation. The footnotes said about 'predisposing to circulatory collapse'. No explanation why though, still looking!
