I find it difficult to find the ulnar pulse; when I do locate it I lose the pulse after a few beats. I was hoping for some good advice.

I think everyone finds it difficult to locate. It isn't the easiest to feel.
Why do you need to?

We've got a practical exam coming up soon, which includes finding and counting various pulses. The ulnar pulse has come up a few times in the previous years.
I could possibly get away with being unable to find it but was just wondering if there are any good techniques for finding it.

Really?! Ulnar?!
I would just pretend in an exam situation, tbh.
Detecting pulses sounds ridiculously simple but it's just one of those things that comes with practice. As long as you're feeling in the right location, there isn't really a trick to it.

It is a sod to feel sometimes though, i tend to go very close to the wrist where it's most superficial, then find the most ulnar sided tendon in the wrist and palpate the medial aspect of that. Also if you dorsiflex the wrist that seems to push the artery closer to the surface.
Practice doing that on yourself and you'll find it.

Ulnar pulse is actually fairly important as you're meant to feel for it every time you do an ABG.

No one feels for the ulnar, you do Allen's test for ABG anyway.

But yeh, in reality no-one EVER does Allen's on the ward, and only the occasional F1 checks the ulnar. I personally do because i'm paranoid, and i'm on Vascular for my first rotation so it's probably good practice to be safe with all the vasculopaths i'll be dealing with.
Also if you're being examined on it, just diving in without doing one of them is probably going to bite you on the bum.

We were told we should do Allen's, but that if we were rushed (aka always) we can just feel for ulnar pulse and that's OK.

Hypothetical question - you have a clear clinical need (e.g. exacerbation of COPD) to do an ABG. The patient in question fails the Allen's test has no palpable ulnar artery on both arms. Are you not going to do the ABG on the radial artery as a result?

Good question. I suppose i'd check with a senior to see if a VBG/CBG would suffice or if there's anywhere else i can get it from, but ultimately if put on the spot i'd do the ABG anyway as the chance of thrombosing the radial artery is pretty small. Depends how crucial the ABG is really though.

What I'm trying to say is that an Allen's test is fairly pointless because it doesn't really alter what you do if your ABG is justified.

Well, if you require an ABG to see the gases (as in COPD) you'll need an ABG. Alternatives to a radial include brachial or femoral (if you feel confident). However, both are end arteries and thrombosing them has the similar (if not worse) consequences as an non collaterallised radial artery.

I think the "if justified" is where it becomes useful though. I think a failed test might put off some seniors from requesting the ABG in cases where it isn't essential.
As i said, i don't actually do Allen's anyway, but i don't see the harm in doing a quick ulnar pulse check.

It sounds a bit bizarre - but if you close your eyes too - you are less distracted. Also use all your fingers and press quite firmly. I have never had a problem finding it.
