All of the attendees at this CGD were treated to a brilliant post-smaccGOLD desert, with an incredible guest speaker, a statistical review of one of the most important publications of the year, a fierce SIMWARS battle, and answers to the age old question: “what the smacc is FOAM?!?!”
Motorcycles: Cases from the Races – John Hinds
John Hinds is not only a fantastic speaker, but also an extremely experienced motorcycle racing doctor. He provided a fantastic insight in to the instantaneous care of trauma at high-speed motorcycle races.
“With average speeds of 135mph* and maximum speeds beyond 200mph*, when they crash, they crash big”
*That’s 217 and 321 km/h in new money
The key crash mechanisms and injuries to really be concerned about include:
- “Hitting the kerb” – they’ve either come to a dead stop or have been launched
- “Broken feet and a low GCS” – think neck and base of skull
- “Head-on collision with an apparently isolated femoral fracture” – The pelvis is probably being held together by the leathers
- “Beware the boot lying in the road” – riders are likely to have realised they are about to crash and put their foot down, leading to lower limb spiraling. Gruesome photos.
Interesting point for all to bear in mind: helmet removal is quite safe. In thousands of cases of helmet removal, John stated they have never had any deterioration due to the removal. Note that there might be significant CO2 buildup within the helmet thus high-flow O2 should be delivered if there is any delay in helmet removal.
The Death of EGDT – Sandra Ware
We were walked through a critical appraisal of what may be one of the biggest studies published this year so far by the hugely experienced Sandra Ware. The American ProCESS study is the first of three publications expected to answer the 13-year-old question: Is early goal-directed therapy (EGDT) superior to protocolised standard care (PSC) or unstandardised ‘usual care’ (UC).
The study was a multicentre, open label (i.e. both the researchers and participants know which treatment is being administered), randomised controlled trial in 31 EDs in the USA of 1,351 patients admitted between March 2008 and May 2013. The primary end-point was hospital mortality prior to discharge or 60 days, whichever came first. Secondary mortality outcomes included the rate of death from any cause at 90 days and cumulative mortality at 90 days and 1 year, while a range of morbidity outcomes were also assessed.
There were no significant differences between any of the primary or secondary outcome measures, although IV fluid administration was higher in the first six hours in the PSC group and vasopressor use in the same time period was higher in the EGDT and PSC group.
What are we to think? Perhaps the simple measures are the most important in the initial phases of sepsis management. This may be the start of a shift away from EGDT and early vasopressor with invasive monitoring to a more clinically directed, pragmatic approach to management of septic patients.

Social Media – Ed Burns
For all of us social media numpties, Ed gave a great talk introducing all things we need to know about how to maximise our knowledge, learning and development online:
What The SMACC is FOAM by Ed Burns on Prezi
There was a highly dynamic and exciting SIMWARS battle held where the key learning points related to resuscitation of traumatic cardiac arrest (TCA) patients include:
- Resuscitation of these patients is not always futile with up to a 7.5% survival to hospital discharge
- Once successfully intubated, achieve adequate ventilation while minimising minute ventilation and high intrathoracic pressures
- All TCA patients should have bilateral open thoracostomies
- Early haemorrhage control with early blood transfusion through large-bore vascular access in sites above the diaphragm
- Consider clamshell thoracotomy in penetrating TCA within 10 minutes of arrest
- Consider perimortem caesarean delivery in gravid patients of greater than 20 weeks gestation in TCA within 4 minutes of arrest
- Chest compressions may be omitted until pre-load and obstructive causes of TCA
