So as promised, and following on from our previous shock episode, this time we've covered the topic of shock in Trauma. It's a massive topic and one that we all, yet again, can make a huge difference for our patients' outcomes. 

There is some crossover as you'd expect from the concepts and assessment that we covered in our Shock episode, so we'd recommend taking a listen to that one first. Make sure you have a comfy seat and plenty of refreshments to keep you going for this one as we cover the following;

• Definition
• Aetiology
• Hypovolaemic shock
• Neurogenic shock
• Obstructive shock
• Cardiogenic shock
• Physiology; Traumatic coagulopathy
• Other diagnostics
• Controlling external haemorrhage
• Pelvic binders
• REBOA
• Avoiding coagulopathy
• BP targets & permissive hypotension
• Fluid choices & supporting evidence
• TEG/ROTEM
• Calcium
• TXA
• Vasopressors
• Preventing hypothermia
• Relieving obstruction
• Interventional radiology
• Damage control surgery

As always we’d love to hear any thoughts or comments you have on the website and via twitter, and make sure you take a look at the references and guidelines linked below to draw your own conclusions.

Enjoy!

Simon, Rob & James

We start off this month with a much talked about paper in the pre-hospital services, what benefit does Pre Hospital Critical Care bring to cardiac arrest victims? We are lucky enough to have the inside thoughts of the lead author, this a really interesting piece of work and will no doubt lead to further discussions, for more information from the author take a look at his thesis here.

Next up we take a look at the utility of troponins in patients that have suffered cardiac arrest, can we use them to evaluate how likely it was that an MI precipitated the arrest?

Last up we have a look at a novel approach of ruling out stroke as the cause of acute dizziness.

We'd love to hear your thoughts and comments.

Enjoy!
