D'oh!

My typo/bad!

Let me try again (I'll use colours - they are easier!)

I have been taught, for IM inj, blue in all but the tiniest dogs, and orange in cats and tiny dogs. Orange is bad in dogs over... erm... 8kgs ish? cause the tiny ness of the needle means it takes longer to inj, and therefore hurts more!

Blue needles for everything else, especially with a volume over 1ml!

I have been taught to use 23g IM in dogs, as it takes too long to inject using 21g, therefore increasing the pain and chance of reaction. 21g in cats, tiny dogs etc, as the volumes used are usually minute.

21g needles are bigger than 23g so technically can inject through quicker, however I think they are too big to be using IM especially in cats etc, cause more trauma etc

23 g or 25 g all the time for IM injections

I just hope I am right on that! Can you ask your tutor to confirm?

23g needle for injecting vetergesic as well as drawing up then. Its so anoying thta you can fail on things that you actually do in practice. I wont make the same mistake twice though!

I had the vetergesic task in my practcals, and I think (although PLEASE don't take this as gospel as I honestly can't remember!) that a 23g needle was the only 'sensible' choice I had, and I used that for both drawing up and 'injecting'. In fact when I think about it, the examiner had a pre-prepared syringe & needle full of air to inj into the stuffed dog, and I am 90% (Not 100%!!!) sure it had a 23g needle on.........

If I remember correctly it was 1.5mls vetergesic I had to 'inject' in the task, so yes, a 23g needle would be appropriate for that volume.

Sorry for the waffle - typing as I think..... hope it helps some!

And yes, I am certain that it is 21g for blood sampling, and 20g for clamoxyl

Yes! We did a practice of that practical in college and I picked the 21g because that's what we use in practice.... I won't forget that now!

Just want to make sure I don't do the same with the blood sample task!

Your logic makes sense, I'd probably go for the 21g and 2.5ml...

so 20g (yellow/white needle) for the clamoxyl task for drawing up & injecting

21g (green) for the blood samoke task

and 23g blue for drawing up the vetergesic and an orange needle 25g for injecting into the muscle.

Got to get that in my head as we use a blue needle for cats in my practice for blood samples and never use a 20g needle for drugs!

PS - you know it's the 20g needle in the clamoxyl task? Since that is what is on the data sheet We always use a 21g in practice!

I think a 21g 5/8" needle is correct as any smaller will potentially damage the cells. A 20g needle may be necessary in a huge pooch, but not for a cat.

As for the syringe, I have always been taught to use the smallest possible, so for a standard 1.3ml hep tube, a 2ml syringe.

If it helps, a friend got this in her practicals and she said the choice they gave her was 2ml, 5ml and 10ml!!
