Welcome to our monthly VetLit Clinical Publication update, where Dr Simon Cook, founder of VetLit.org, provides an overview and update on recently released studies from a wide range of veterinary publications.
Do you give volume to dogs with pericardial effusion? Do you avoid giving volume to dogs with pericardial effusion?
This study asks the questions – is there a clear advantage to volume expansion, and, is there tolerance of the fluid you prescribe? One debate being that, all other things being constant, if you could get volume to and through the heart then it would be useful. But you “can’t” get it there and all other things aren’t constant!
There was no discernible advantage documented in these animals, though it was underpowered. Could there be some patients that do benefit – yes. There were two very interesting studies in people cited within this article – evaluating the patients in which volume provision was helpful [references 4 and 28]. Will a dog be tolerant, or become tolerant of the volume as soon as you relieve the tamponade? Yes, most likely. If you’re in doubt, is it ok to give volume? Yes. But still the most useful thing you can do is drain the effusion 😉 (We could ponder this physiology for a while..!).
Simon graduated from the University of Bristol in 2011 with degrees in veterinary science and veterinary pathogenesis. After a rotating internship at the Royal Veterinary College and two years in a busy 24 hour small animal hospital, he completed a residency in emergency and critical care at the Royal Veterinary College. He is currently a senior lecturer in emergency and critical care at the Royal Veterinary College, London. Clinical and research interests combined include immunomodulation, cardiovascular monitoring, patient side ultrasonography and aspiration pneumonia. VetLit.org is his passion project, making literature more accessible to anyone and everyone.
