So in this episode we’re going to be covering crush injury.  When you think about it, visions of falling rocks, industrial accidents and high speed RTCs may come to mind, but actually a crush injury can be sustained in a huge variety of ways without such vivid circumstances. Definitions according to the Faculty of Prehospital Care are that; ‘A crush injury is a direct injury resulting from crush.  Crush syndrome is the systemic manifestation of muscle cell damage resulting from pressure or crushing’ So in the episode we’re going to run through all of the bits that we normally cover, from pathophysiology, to presentation and onto treatment. We'll also be looking at the controversy and evidence behind tourniquet use, fluid therapy, electrolyte management and much, much more! Once again we'd love to hear any comments or questions either via the website or social media. Enjoy! Simon, Rob & James

Welcome back to the podcast and three great papers for May's episode! First up we take a pretty deep look into refractory VF. This follows on from our our review of DOSE-VF in December '22's papers of the month and our recent Roadside to Resus on the topic. In that we discussed the possibility that many of the cases we see at pulse checks as being refractory VF may actually have had 5 seconds or more, post shock, where they jumped out of VF but then reverted back into it. This paper is a secondary analysis of DOSE-VF and reveals what really happen to these 'refractory VFs' by interrogating the defibrillators. What difference will it make to our strategy for recurrent and refractory VF? Next up we take a look at elderly patients presenting to the Emergency Department with abdominal pain with an analysis of the features that predict a serious abdominal condition. Lastly we look at the how different pressures exerted to the facemask when ventilating neonates can make in terms of bradycardia and apnoea.

Lower back pain is a really common cause for patients to present to primary care, urgent care and emergency care. Thankfully many of these cases are self limiting, but somewhere in the region of 1:300 patients with back pain in the ED will have Cauda Equina Syndrome. Cauda Equina Syndrome is something that is challenging for all clinicians because many patients with simple lower back pain may have many similar symptoms,  but if we miss it, or if there is a delay to surgery that can lead to potentially avoidable long-term disability for our patients and on top of that its a major cause of healthcare litigation. And we’re not talking about a delay in weeks being a problem here, we’re talking about hours to days, with big  potential complications like impaired bowel/bladder/sexual dysfunction or lower limb paralysis - so you can see why litigation is a big part of some missed cases. In this episode we run through the the signs, symptoms, investigations and treatment with a strong reference back to the underlying anatomy and disruption. We also cover the recently published national Cauda Equina Pathway, which is a great resource but poses some real challenges in it’s implementation!

Cauda Equina Syndrome; Roadside to Resus

Welcome back to the podcast! Three more papers covering topics that are relevant to all of our practice. The importance of removing wet clothes from patients is often discussed, both to prevent hypothermia and increase patient comfort. But how important is it to get wet clothes off and is it something we can defer to a different point? We start off taking a look at an RCT on this very question. Next up another RCT, this time looking at the efficacy of morphine, ibuprofen and paracetamol for patients with closed limb injuries. Which one, or combination, would you think would be most efficacious… Lastly, following on from our most recent Roadside to Resus episode, we take a look at a paper on the association between end tidal CO2 levels and mortality in prehospital patients with suspected traumatic brain injury. This paper highlights really well the need understand the fundamentals that contribute to ETCO2 when applying to clinical practice.  Once again we’d love to hear any thoughts or feedback either on the website or via X @TheResusRoom!

April 2024; papers of the month

End Tidal CO2, or ETCO2 for short, is something that’s talked about pretty often in Emergency and Critical Care and that’s because it’s used a lot in the assessment and treatment of patients! It’s got a big part to play in airway management, resuscitation, sedation and is also increasingly used in other situations. Some of these applications have some pretty strong evidence to back them up but others are definitely worth a deeper thought, because without a sound understanding of ETCO2 we can fall foul of some traps… ETCO2 is a non-invasive measurement of the partial pressure of CO2 in expired gas at the end of exhalation. Ideally we’d like to know what’s really going on arterially with the partial pressure of arterial CO2 but we can use the end tidal because that’s an easy reading to get from exhaled breath, when it will most closely resemble the alveolar CO2 concentration. Its value is reflective of ventilation but also really importantly is affected by the circulation, the circuit and how it’s applied. In the podcast we run through all of these aspects, its application to clinical care and also some of its pitfalls.  Once again we’d love to hear any thoughts or feedback either on the website or via X @TheResusRoom!

Welcome back to the podcast, a new month, three more papers and discussion around the topics. We kick off with a paper comparing mechanical ventilation in CPR compared to the more traditional hand ventilation; what difference does the machine make to ventilation in arrest and should we be changing to this strategy as a standard? We've talked about aneurysmal subarachnoid haemorrhage a fair amount on the podcast and the second paper looks at the effectiveness of lumbar CSF drain compared to standard care with some pretty staggering results! Lastly we take a look at a paper exploring decision making in prehospital trauma, specifically with regard to blood transfusion. This is a great paper to focus on the complexities of decision making, understand decision making strategies, recognise areas of weakness and consider how aspects of these can be used educationally and to improve emergency care for our patients.
