RCEM ’15 in Manchester has been a sell out! So for those of you that weren’t lucky enough to be here, here’s what’s been going on on Day 2!

Ultrasound

Erik Sloth, a Denmark-based expert in ultrasound kicked off the morning auditorium session on the utility of ultrasound in identifying diagnoses and pathology that may otherwise be missed, although these diagnoses would not always correlate with patient or indeed gorilla-centred outcomes! (NB Erik has recently been involved in ultra sounding a gorilla as a patient).

Framework for medical ethics

EM ethics is messy Tim Coats told us, in a following presentation, and we must make decisions rapidly based on inadequate information. To help us Tim presented us with a framework for making difficult decisions regarding patient care by breaking the problem down into three areas:

  • Protection: composed of weighing up benefice (doing good) and non-malifice (avoiding doing harm)
  • Respect: involving the patient in decisions about their own care. (Remember that patients may have different views and set of values)
  • Justice: matching response to need and considering application of the law.

There is seldom a right answer and every decision involves shades of grey.

Patient Handover- “The Bermuda Triangle”

Rommie Duckworth (@romduck), a fire officer and a prehospital care provider, talked to us about mission critical communications. Ron highlighted the dangers of suboptimal communication and the morbidity and mortality that can result.

“The problem with communication is the perception that it has been accomplished’

Ron talked about the importance of having a shared mental model in handover with:

  • Focused priority
  • History of prior care
  • Current state
  • Immediate needs

HEFT EMCAST (@HEFTEMCAST) has an excellent post on this.

Surgical Procedures at the Roadside

Gareth Davies covered this session which challenged the “scoop and run” believers. Talking about roadside thoracotomies, he pointed out that picking the right patient, with the right injury at the right time (see the slide below)

…….and actual outcomes from roadside thoracotomies seem pretty impressive, as the following slide suggests!

IMG_8234

Gareth reminded us that the brain has an ischaemic time of 4 minutes so if you’re going to perform a thoracotomy time is of the essence and you need to consider if you are in or out of the window of opportunity.

He finished off the session talking about REBOA. This was a superb session and although these procedures are rare, they really seem to define the proactive move forward of the EM clinician who can see and sort the breadth of critically ill patients and truly master resuscitation.

RCEMFOAMed’s Dave McCreary (@dmcmcreary) had interviewed him after the first roadside REBOA performed by London Air Ambulance (@LNDairamb) and you can listen to the podcast here.

The heart under stress

The Things Nobody Told You About Troponin

Troponins are either a diagnostic life saver or a pain in the proverbial depending on your perspective. The high sensitivity troponins (or low specificity troponins as theyre sometimes called) are tricky.
Rick Body (@richardbody) managed to organise this conference and pull off a cracking talk at it too. Rick has the rare combination of a world class researcher an world class presenter all rolled into one.

He had some important criticisms of the recent NICE guidelines (of which he was actually part) in particular that the 3 hr rule out advice is based more on QALY than it was on evidence.

He also advised caution with the POC assays used in a 0 and 3 hr rule out. The sensitivities just arent great.

Mens ACS is From Mars, Womens ACS is From Venus?

Nick Mills who gave this presentation, is a cardiologist from Edinburgh and heavily involved in ACS research. His talk focused on the sex specific differences in ACS – we miss it more often in women and they seem to do worse, he said.

He talked about sex specific thresholds for diagnosing ACS. Nick is involved in the HIGH STEACS trial which is almost done which will hopefully give us some good info to add to this question.

Paediatric stream

This stream was a busy one, and the turnout seemed to have surprised the organizers who quickly had to swap the rooms around to fit those us with interest in paediatrics into the same space.

Well done to the organisers for sorting that out swiftly! Jeremy Tong (@jez_tong) spoke us about the #PaedSepsis6 updates which were released last month. The difficulty clinicians generally have with sepsis is to find the 1 child in 1,000 who will be septic, he said. The sepsis trust have now produced a toolkit to enable better identification and management of these, which I do suggest you have a good look at.

Rachel Rowlands (@rachrwlnds) followed with an inspiring talk entitled looking for learning when a child dies with helpful tips like thinking about what it must be like for families in our departments, who are given bad news. My favorite one was to think about bereavement boxes for them, with foot and hand print kits. Rachel also snuck in a helpful reminder (for those of us who arent paranoid about this already) that button batteries are evil. RCEM has endorsed the following guideline for management of button battery ingestion and this is a nifty blog from St.Emlyns for those who want to read more.

The ever-philosophical Damian Roland (@Damian_Roland) spoke to us about delivering quality PEM care, which he said needs to be: -Safe -Effective -Person Centered -Timely -Efficient -Equitable He also gave a small snippet of his PhD work, on competence and confidence in trainees, which reminded us very much about the Dunning-Kruger effect (see graph), and this excellent blog by Nathalie May (@_NMay) on imposter syndrome.

Picture taken from www.digitalintelligencetoday.com Prof Alan Emond told us how the MISTIC Study is trying to identify a clinical prediction rule for post-burn illness. Prelimary results indicte the following independent risk factors:

  • Burn size
    Age of child
    Severity of the illness
    Use of Biobrane

We look forward to having the full results for use in the ED soon.

Sepsis Sorting out the Confusion

Screen-Shot-2015-09-29-at-13.57.51

Some really interesting questions here relating to all aspects of sepsis and presumably set up as a response to the Sepsis session from SMACCUS (plug in to the HEFT EM SMACCback here).

Scott Weingart (@emcrit) talked about the safe and effective use of peripheral vasopressors when administered through a well sited peripheral IV line. He also mentioned that the utility of US for IVC and cardiac output calculations perhaps didn’t hold the utility that he and others previously believed.

What’s next for EM USS?

This Q&A session on emergency medicine ultrasound with Mike Mallin, Matt Dawson and Rajat Gangahar. The audience had lots of pertinent questions during this session; these are some of our highlights:

  • Concept of USS as part of the clinical exam, you should put in the context of your history and examination, Mallin discussed how he likes to see his patients face and reactions when doing USS.
  • How do we get colleagues from other specialties to accept our diagnostic findings with USS? Mallin and Dawson both pointed out this takes time, you need to demonstrate that your scans can add value. Show the specialty the scans and slowly start to win their trust. This will not happen overnight!
  • FAST Scans and Trauma are they dying out? Only valuable in stable patients who have already had a CT for training purposes and in patients who acutely become unstable.

Sepsis

Ron Daniels spoke about the probability that signs of SIRS will be dropped shortly and other red flags will be instituted to screen for what we now think of as severe and septic shock.

He also spoke about the difficulty in meeting standards and guidelines on all patients with sepsis and talked about possible implementations such as sepsis teams in a similar vein to trauma teams.
Fluids in Resus
IMG_8250-e1443540450584
Tim Harris confessed to his “guilty pleasure” of ultrasound and how the modality should be guiding our fluid resuscitation with simple observations of cardiac motility and IVC measurement. He spoke about measuring cardiac output in resus with echo. If we are going to be trying to improve it then we should be measuring it before and after, he said.

Scott Weingart on the CRASH Surgical Airway
IMG_8252-e1443542537995
Nobody should die without a definitive airway,” Scott Weingart (@EMcrit) told us in a lively and entertaining talk on how not to mess up the surgical airway and be mentally prepared.

Ten ways to mess up the surgical airway, he said:

  1. You are scared to make the cut discuss with the team in the room the possibility of surgical airway, get you kit ready and feel the anatomy for all pts.
  2. Think there is a back up that is not there.. surgeons do not have the right mindset to be doing this procedure they should NOT be your back up plan!
  3. We dont know the anatomy practice finding anatomy on patients who dont need this procedure!
  4. Scared of blood they will bleed but no-one will exsanguinate from a midline cut
  5. We injure ourselves or our team Protect your face, blood will spurt when you make the cut!
  6. We regress to a misperception of safety and familiarity – we are used to seldinger techniques but needles fail ..USE a scalpel!
  7. We choose the wrong way to cut: Use a Scalpel Finger Bougie technique. Watch Scotts video on how to do a surgical airway
  8. Cant feel the anatomy when you make the cut you will be able to feel anatomy!
  9. Failure to train build a trainer and practice every six months!
  10. Failure to consider an awake cricothyroidotomy

Haemostatic Resuscitation in The Defence Medical Services

Lt. Col Tom Wooley talked us through some of the history of blood products in trauma resuscitation. How we managed to move from World Wars I & II, where they had realised the utility early of whole blood transfusion to the 1980s and ATLS with its recommended initial 2 litres of crystalloid and make to today where we have moved back to blood products and research into the coagulopathy of trauma.

He concluded that in the future we need to continue research into component therapy, how we use it, and whether there are viable alternatives to be used in the early stages of the next major conflict.

Haemostatic Resuscitation Laboratory Research

The main thing to take from this talk by Emrys Kirkman and Sarah Watts was some interesting pathophysiology of coagulopathy in trauma, how it relates to tissue hypoperfusion and endothelial damage, and then a walk through of the results of their trial on the benefits of prehospital blood products to prevent coagulopathy. Interestingly in this animal model there seems to be a benefit of PRBCs alone, as opposed to with FFP. (Karim Brohis name may have been mentioned once or twice).

Is there a Clinical Need for REBOA?

Unfortunately Jonathan Morrison, who was originally meant to give this talk, wasnt able to make it, but the Chair valiantly took us through his slides. There have been animal trials supporting REBOA, he said, and obviously a couple of very successful individual case reports, but conversely the largest retrospective analysis performed showed REBOA patients actually had a worse mortalityso the jury is still out.

Leaving you with that thought, you will have noticed that it has been a jam-packed day with some superb speakers and diverse but well founded opinions. Have a listen to the podcast for some snippets of some of the speakers and other topics of the day.

We’ll see you tomorrow!
