https://www.vetnurse.co.uk/f/clinical-discussions/32066/wound-drain-placement I am loving the discussions and sharing that has been happening recently, so here&#39;s another talking point...... Drain Placement……..what’s wrong in this picture?? The answer is there are two ends visible from the same penrose drain.

It&#39;s not considered necessary to have 2 holes as the fluid drains ventrally, so the extra hole serves no useful purpose but is a potential route of contamination.</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/176532?ContentTypeID=1Thu, 08 Oct 2020 17:21:52 GMT1a0763ec-3885-442c-853e-6cef656dfec5:596755ff-0203-4428-9a13-003c5d778210apache<p>Hi. Not meaning to be an arse but do you have some papers that support this? I frequently use them in contaminated wounds where I will also flush via the top hole. In fact I can&#39;t think of a case where I would use a penrose drain and not have the animal on suitable antibicrobial therapy. I also know that by exiting above and below the wound that the drain remains in place throughout the deadspace - how would I know that if all I can see is the ventral tail and I have no dorsal attachment (I place single interupted suture at each end).</p> <p>I would absolutely agree when discusssing things like vacuum drains - single point in the wound bed.</p> <p>(I am self aware of confirmation bias - but I have used 100&#39;s of penrose drains like in the RHS picture and I struggle to remember a problem that would be associated with a second hole)</p><div style="clear:both;"></div>
