I would like to know how do you assess for bruits and thrills of hemodialysis access sites? I realize this maybe a stupid question but I am a returning Lpn after many years and do not remember this topic at all.
Welcome back to nursing..
Normally, the bruit is continuous (heard during systole and diastole), soft, and low-pitched. If it becomes discontinuous (present during systole only), harsh, and high-pitched, the access may be stenotic.
You may also note that the palpable thrill, which is normally continuous and soft, becomes discontinuous, and sounds like a water hammer (a quick, powerful beat that suddenly collapses).
I hope this helps..and it wasn't a stupid question at all!
It shows you have the intellegence to ask, what you don't know or remember.
