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
