I don't think 'really critical patients' are the issue here. Obviously, a critical patient is going to have issues that may require higher sterility. And, a critical patient is far more likely to have a catheter placed.
Absolutely a critical patient should have a catheter placed. I just wanted to add some potentially broader perspective to the discussion - clearly we are not just addressing the op's question here so why not add information on varied patients?
I have also been working in vet clinics as a veterinary technician for 7 years. I have seen plenty of animals flip out because of the sound of clippers. However, the majority of them are fine.
Which was my point. To me "some patients flip out" is not adequate reasoning in my opinion to not clip in ALL patients.
I have yet to see a pet get sepsis from a simple venipuncture due to not shaving.
I didn't say I had seen it either - in fact I said I doubted that anyone here had.
I have seen pets get insanely horrible skin infections from us clipping and scrubbing the area before placing a catheter simply because the pet will not stop licking the area. Most owners are unaware that their pet's insane licking of the area we shaved can cause a problem and I have seen some bad infections because of it. The shaved area bothers quite a few pets and scrubbing the area as much as we do can leave it even more irritating and raw. One of our doctors tries to shave as little as possible before placing a catheter because she has seen more severe infections from a pet licking at the area once the catheter is out than a pet going into sepsis from our placing of the catheter (which has never happened).
I think if your patient is able to lick at its leg so much that it gets a horrible skin infection, thats poor patient management. Obviously I understand owners are not always as attentive - but if it was a common complication I was seeing, I would probably start warning owners to watch for it and call us/ come get an ecollar if the dog was licking at it often. And if scrubbing the area results in raw, irritated, infected skin, you're scrubbing too hard - you only have to remove surface dirt, then its your contact time which actually provides sterility.
I have seen numerous "fevers of unknown origin" (lol) which have been traced back to catheters just in the last few months. Catheter site prepartion and management really does go a long way - and its so little effort for what can avoid a lot of trouble.
Once again, im not saying its ABSOLUTELY NESSERCERRY to clip for blood draw. I am saying that some people definately do - without complications - and some people definately don't - similarly without complications. I feel comfortable with my blood draw protocols and preps and my catheter protocols and preps - both of which have been developed by critical care specialists.
Obviously if I had some lab in with gross reactive skin I would not clip for a simple blood draw. Obviously your protocols should be adaptable for your particular patient. And I do think we should be interested in these discussions - we have a lot to learn from each others protocols and reasonings behind it etc. And I do feel we should be regularly critically evaluating a lot of our protocols, including the little ones.
