This month we've got four cracking UK-led studies that really speak to how pre-hospital and emergency medicine continue to evolve, not just in the kit and skills we use, but in how we think about the whole patient journey.

We'll start with a paper fromAnaesthesia with Pallavicini et al., exploring pre-hospital central venous access for patients in haemorrhagic shock. Drawing on London's Air Ambulance experience, it shows that large-bore central catheters can be placed safely and effectively, delivering earlier transfusion and improved survival to ED arrival. It's high-stakes medicine in extreme circumstances, and this study gives some of the best real-world data we've seen on it.

Next up we look at the impact of a paper that's genuinely changed national practice from Aljanoubi et al. in Resuscitation, looking at what happened after the AIRWAYS-2 trial landed. You'll remember AIRWAYS-2 showed no functional benefit of tracheal intubation over supraglottic airways in OHCA, but did it actually shift behaviour? This registry study of over 70,000 patients shows that it did - and dramatically. The rate of pre-hospital intubation has fallen from around 44 percent in 2014 to 14 percent by 2020, with a clear inflection right after the trial's publication. Real-world proof that evidence can truly change practice.

Then, we turn to two linked Delphi consensus studies from Tim Nutbeam and colleagues, published in the Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine. The first, optimising the care of the trapped patient, develops expert-endorsed principles for managing physically trapped casualties, marking a real shift from "movement-minimisation" to time-sensitive, patient-centred extrication. The second, prioritising time-critical injuries and interventions, complements that work by defining which injuries and treatments truly can't wait — creating a shared language for multi-agency teams at the roadside. Together, these papers show how thoughtful, collaborative UK research is shaping the next generation of trauma and resuscitation care — evidence, consensus, and practice all pulling in the same direction.

These latter two papers are from the team at IMPACT; The Centre for Post-Collision Research, Innovation & Translation. We've been lucky enough to collaborate with the team and deliver an online Extrication course which is now available! A bit about the course;

Target audience:

Fire and Rescue Service personnel, Police officers, community response scheme members, and clinicians who respond to collisions or who wish to update their awareness of consensus extrication guidance.

Aims:

To improve awareness and adoption of evidence-based, patient-focused extrication principles among operational responders by providing a concise, accessible, and practical educational resource that bridges consensus guidance and real-world operational practice.Learning outcomes:

The course will enable participants to:

• Describe the evidence base underpinning contemporary extrication practice.
• Apply a patient-focused approach to decision-making during extrication.
• Employ endorsed decision support tools, including EXIT decision aids, to case-based scenarios.
• Recognise and challenge outdated or unsafe norms in extrication practice.

How, when and why to make the call…

The pre-alert is one of the most powerful and sometimes most painful parts of emergency care. It can feel like the Spanish Inquisition, trigger tension between pre-hospital and ED teams, or drop another challenge into an already overflowing department. But done well, a pre-alert isn't an irritation; it's an opportunity to line up critical care for the next patient and genuinely improve outcomes.

In this episode, Simon, Rob and James break down The UK NHS Ambulance Services and Emergency Department Pre-Alert Guideline, jointly released in July 2025 by RCEM and the Association of Ambulance Chief Executives. It's the first national attempt to give clear, shared expectations on who to pre-alert, what to say, and how to receive those calls, it's full of practical recommendations for both sides of the phone.

We kick things off with a review of the evidence base, including brand-new studies showing just how varied pre-alert practice is across the UK. From inconsistent criteria and mixed training to the problem of "pre-alert fatigue", the data make a strong case for standardisation.

We then walk through the new guideline's key principles: pre alerting for pre-specified physiological parameters or specific conditions.

We finish off with top tips for making and taking better pre-alerts - selling a story, leading with the headline, and understanding what the other side actually needs. This episode combines frontline pragmatism with real-world research and might just make your next pre-alert smoother, faster, and better received.

This month we've got three really interesting papers that shine a light on aspects of cardiac arrest management that many of us will recognise from clinical practice.

First up, we look at the feasibility of arterial line placement during ongoing cardiac arrest in the Emergency Department. In our SPEAR episode we talked about the balance between securing invasive monitoring versus the potential distraction from other essential parts of resuscitation. This paper takes a pragmatic look at whether arterial access is achievable in that critical period in the Emergency Department, the success rate and the time required.

Next up, we look at a paper that helps to give us a more accurate feel for the rate and predictors of high-risk adverse events for Emergency Department paediatric ketamine sedation.

Our final paper looks at ultrasound during cardiac arrest. Specifically, whether the hands-off time during the pulse check are longer with traditional manual checks or with ultrasound. This systematic review and meta-analysis puts some numbers to the best way to minimising hands-off time.

So whether you're a regular on the arrest team, sedating children, or supporting resuscitation from the periphery, these papers provide some useful food for thought on where our focus should be in those critical minutes.

a focus on its acute presentations and the care we can deliver to improve outcomes for our patients.

Sickle cell disease (SCD) is a lifelong inherited blood disorder that affects over 15,000 people in the UK, and millions worldwide. It's caused by the production of abnormal haemoglobin molecules, which distort red blood cells into a crescent, or "sickle," shape. These rigid cells can block small blood vessels, leading to painful vaso-occlusive crises and organ damage.

While the condition has long been most prevalent in parts of Africa, the Middle East, the Mediterranean and India, today it's a global health issue, and one we encounter regularly in UK emergency care. Tragically, failings in care have too often led to avoidable harm. The 2021 parliamentary report "No One's Listening" laid bare some of these cases, highlighting missed opportunities, poor awareness, and systemic issues that cost lives, such as the death of Evan Nathan Smith.

So why are we revisiting this now? In 2024, RCEM published new Best Practice Guidelines on managing sickle cell disease in the ED. These provide clear, evidence-based standards for recognition, triage, analgesia, infection control, and safe discharge. In this episode, we take you through the key elements;

• Pathophysiology – how a genetic mutation drives sickling, vaso-occlusion and inflammation.
• Clinical presentations – from painful crises and acute chest syndrome, to stroke, anaemia, infection, priapism and pregnancy-related complications.
• Recognition and triage – why timely pain control within 30 minutes is a must, and how to spot red flags.
• Investigations and treatment – including the role of reticulocytes, the importance of knowing a patient's baseline haemoglobin, and principles of analgesia, transfusion, oxygen, and supportive care.
• Discharge and ongoing care – ensuring safe, joined-up planning, and involving haematology and specialist pathways wherever possible.

The take-home message? Every sickle cell crisis is a medical emergency. We need to listen to patients, escalate early, involve haematology, and deliver care that meets the standards they deserve.

Welcome back to September's Papers of the Month. We've got three cracking studies for you this time, each tackling really core questions in pre-hospital and emergency care and each giving us plenty to chew over when it comes to the evidence base and what it means for our practice.

First up, we're heading down under to Sydney with the PRECARE pilot feasibility study on pre-hospital extracorporeal CPR for refractory cardiac arrest. Now, we all know survival from refractory OHCA is pretty dismal with conventional CPR alone, and that the big limiting factor with ECPR is time to flow. So could we meaningfully shorten that window by bringing ECMO to the roadside rather than the hospital? This study tested whether pre-hospital physicians could safely and effectively deliver ECPR on scene and the results are some of the fastest low-flow times yet reported. But of course, feasibility is only one piece of the puzzle…

Next, we're back in the UK with a service evaluation from Devon Air Ambulance looking at endotracheal intubation by critical care paramedics during cardiac arrest. Airway management in OHCA has always been a hot topic, with long-running debates over supraglottic devices versus intubation, and questions about who should be putting a tube in. This six-year dataset explores how structured education, theatre placements, and the introduction of video laryngoscopy have changed practice and whether CCPs can consistently meet the ERC's benchmark of 95% success, or more, within two attempts.

And finally, we're heading to Switzerland with a study on the HOPE score in hypothermic cardiac arrest. Hypothermia remains one of those rare but high-stakes presentations where patients in cardiac arrest can sometimes make remarkable recoveries if we select the right ones for extracorporeal rewarming. The HOPE score is designed to guide those decisions by predicting survival. This study takes a retrospective cohort across two hospitals and asks: does the score actually deliver in real-world practice, and can it help avoid futile attempts at ECLS?

So, three papers, ECMO on the roadside, paramedic-led intubation in cardiac arrest, and the precision of the HOPE score. As ever, plenty to think about for both the evidence and our day-to-day practice.

Welcome back!

First up a paper to challenge the way we think about rhythm recognition in cardiac arrest to start with, looking at the rate of VF identified on echo but not on the defibrillator.

We have a huge amount of strategies to rule out acute coronary syndrome in the UK, our next paper looks at the clinical effectiveness of these, whilst also giving us some hugely important information about the incidence of ACS in those presenting to Eds.

Finally we look at a paper quantifying the effect of hypertonic saline in those patients with a TBI.

Welcome back to Papers of the Month! Three more papers to both inform and challenge our practice across the spectrum of emergency care.

First up we look at a systematic review and meta-analysis on noradrenaline vs adrenaline for our medical post-ROSC patients; what evidence exists out there and should we all be delivering noradrenaline as our first line treatment for those with shock?

Next up a paper to really challenge the treatment algorithm for status epilepticus in paediatrics, with an RCT of midazolam and ketamine versus midazolam alone. There are some huge differences here in the form of termination rates and some great discussion to be had around the specifics of the paper and how that might translate into future practice.

Finally we look at a paper assessing the impact of i.m. versus i.v. metoclopramide for migraines and acute severe headaches. The paper looks at the impact of length of stay within the Emergency Department and also the efficacy of the treatment.
