London Trauma Conference Day 4 by Dr Louisa Chan
It’s the last day of the conference and new this year is the Neurotrauma Masterclass running in parallel with the main track which focuses on in-hospital care.
We heard a little from Mark Wilson yesterday. He believes we are missing a pre-hospital trick in traumatic brain injury. Early intervention is the key (he has data showing aggressive intervention for extradural haemorrhage in patients with fixed dilated pupils has good outcomes in 75%).
Today he taught us neurosurgery over lunch. If you have a spare moment over then go to his website and you too can learn how to be a brain surgeon!
Dr Gareth Davies talks about Impact Brain Apnoea. Many will not heard of this phenomenon. Clinicians rarely see patients early enough in their injury timeline to witness
Essentially this term describes the cessation of breathing after head injury. It has been described in older texts (first mentioned in 1894!) The period of apnoea increases with the severity of the injury and if non fatal will then recover to normal over a period of time. Prolonged apnoea results in hypotension.
This is a brain stem mediated effect with no structural injury.
The effect is exacerbated by alcohol and ameliorated by ventilatory support during the apnoeic phase.
Associated with this response is a catecholamine surge which exacerbates the cardiovascular collapse and he introduces the concept of Central Shock.
So how does this translate into the real world?
Well, could we be miscategorising patients that die before they reach hospital as succumbing to hypovolaemic when in fact they had central shock?
These patients essentially present with respiratory arrest, but do well with supported ventilation. Identification of these patients by emergency dispatchers with airway support could mean the difference between life and death.

Prof Monty Mythen spoke on fluid management in the trauma patient after blood (not albumin, HES or colloids) and Prof Mervyn Singer explained the genetic contribution to the development of MODS after trauma.
1. Task focus kills
2. Situational awareness saves lives
3. The best communication is non verbal
4. Train yourself to listen
Prof Susan Brundage is a US trauma surgeon who has been recruited into the Bart’s and the London School of Medicine and the Royal College of Surgeons of England International Masters in Trauma Sciences for her trauma expertise.
She tells us that MOOCs and FOAM are changing education. Whilst education communities are being formed, she warns of the potential pitfalls of this form of education with a proportion of participants not fully engaged.
The Masters program is growing and if you’re interested you can read more here.
This has been a full on conference, with great learning points.
Hopefully see you next year!
