Exit Block: What it is and why it’s dangerous.

This a great video from the college on the significance of exit block and the effects it’s having on our patients and staff. This, along with the recruitment crisis is, I think the biggest issue facing emergency medicine in both Ireland and the UK.

Well worth a watch.

Recent controversies in sepsis

Below is a recent talk I prepared for a teaching meeting for the ICU and ED staff. Unfortunately I was still on my train when I was due to give it so here it is online instead.

CEM FOAMed network

CFN Logo

The College of Emergency Medicine is the body responsible for training all the wonderful UK emergency medicine trainees and represents the speciality in the UK. The trainees in Ireland do the UK exams so the specialties in both countries have a fairly close relationship.

The college’s main online educational presence in recent years has been the ENLIGHTENme platform. There’s been some good stuff on there but it’s behind a log in and not immediately accessible in the way FOAMed resources have been.

With the rise of FOAMed and it’s influence on education of emergency physicians, it’s only natural that the college would want to embrace the idea.

Simon Laing (of the HEFT EM Podcast) is the college lead for this and he has been involved in recruiting people from the different regions of the UK and Ireland to provide FOAMed resources. Ultimately the goal is to ‘map’ the college curriculum. Somewhat similar to my own little anatomy project but on a much broader scale.

The UK exams for emergency medicine are a different beast to the Aus/NZ ones so it’s a natural that there’ll be a need for some more specifically directed resources.

The CEM FOAMed Network (rejoicing in the acronym CFN) is a project in development. The website is in the pipeline and the introductory podcast is now live on iTunes.

Please check it out and look out for more FOAMed resources in the near future.

Tasty Morsels of EM 041 – Acute Urinary Retention

[Featured Image: Frivadossi, Wikimedia Commons]

As always, this is from the ever expanding google doc on bits and bobs I read and learn from.

This time:

ED Management of acute urinary retention. EB Medicine

  • Causes
    • Men – think prostate
    • Women – bladder masses, gynae surgery and prolapse
    • Drugs: calcium channel blockers (i didn’t know this), anticholergics (i did know this one)
    • Spinal cord compression is probably the real emergent cause we need to think of
    • In a similar manner to other neuropathies, diabetics can get a diabetic cystopathy resulting in AUR.
  • The big take home should be this: you need to bloody well examine them. There is a real (and justifiable) desire to just slip in the catheter (or worse get someone else to do it) and get disposal nice and quickly. But as simple as most AUR is, you will miss important things (say spinal cord compression, or a penile tumour, especially in the patient with dementia or non-verbal patients) if you don’t physically get involved with the gorey details.
  • there’s some ‘himming’ and ‘haaing’ over whether to put a finger in the rectum. The main concern seems to be in prostatitis and seeding the blood with a prostate exam. They’re right to say that there’s no evidence of this causing harm. But that works both ways – there’s no evidence either way. There’s not a great deal of diagnostic value here I don’t think. The bigger issue is whether to put a catheter through an infected prostate. I figure if they’re in retention then I do it, and they get a nice chaser of gentamicin and an admission.
  • there’s some interesting stuff on urine samples for prostatitis. You can collect wee at lots of different points of the wee cycle and then massage the prostate a bit and get another few mls. There’s even a study looking at semen cultures for prostatitis. I imagine if I had prostatitis the last thing I might be able to do is provide a semen sample…
  • getting the patient to exhale when the tip is at the prostate seems to be of some use in relaxing the relevant sphincters
  • an episode of hypotension following bladder decompression is common due to a reflex response in reduced vascular resistance. Doesn’t mean the you don’t have to think about whether that patient’s severe abdo pain was actually a AAA rather than AUR…
  • they (sensibly) state that if it’s a simple catheter and no reason to think infection then antibiotics are not indicated. Very different from the raging, septic prostatitis
  • they quote the common figure of 2 in 3 patients requiring repeat catheterisation if the catheter is immediately pulled. They also note that those with a spontaneous AUR (which is likely prostatic hypertrophy in origin) is more likely to need a second catheter than those with a precipitated cause (eg infection or constipation).
  • they suggest that the 2 in 3 rate of recurrence mandates that the catheter is left in whereas I think that “hey, I have a 1 in 3 chance of not needing this – i’ll take those odds and come back if I can’t pee again”
  • catheters that get stuck and can’t be removed are usually due a ridge forming on the balloon during deflation and can be dealt with very slow reinflation and deinflation. The inflation channel can also be cut. Interestingly they say that filling the balloon with 10mls of mineral oil will dissolve the balloon in about 15 mins and allow removal. I have no idea if this applies to all makes.

IAEM 2014

The Irish Association for Emergency Medicine are hosting their annual scientific meeting this year in Dun Laoghaire. They’ve just launched the website for the event where you can find all the info you need. This year’s event is being hosted by one of former hospitals, St Vincent’s University Hosptial Dublin where both this site’s own David Menzies and our training program director, John Ryan are based.

It’s exciting to hear that FOAM’s own Scott Weingart is coming as our keynote speaker. Upstairs care, downstairs and all the way across the pond it seems!

It’s sure to be a great event and of course it’s open to those both north and south of the border and it would be a delight to see even a few of you over from the UK too.

As with most scientific conferences, there is the opportunity to submit posters and oral presentations and all the details are on the site.

See you there.
