Welcome back to July's Papers of the Month.

This month we've got three papers that tackle some of the biggest questions we face in emergency and critical care medicine. They're all very different studies, but each one looks at an intervention that many of us use, or at least think about, on a regular basis.

First up, we look at ARISE FLUIDS, a major trial examining one of the longest-running debates in sepsis care. Should we be reaching for fluids or vasopressors first in septic shock? We've spent years worrying about giving too much fluid, and equally worrying about starting vasopressors too early. This study gives us some of the best evidence yet about what happens when we take a more restrictive fluid approach and start vasopressors earlier.

Next, we move to cardiac arrest and the BIHCA trial, looking at sodium bicarbonate during in-hospital cardiac arrest. Despite guideline recommendations and a lack of convincing evidence, bicarbonate continues to be used in many arrests around the world. This study finally gives us some high-quality data on whether it's actually helping our patients.

And finally, we head back to the ECG with a fascinating paper looking at the lead V5 T-wave to R-wave ratio as a marker of right ventricular dysfunction in pulmonary embolism. It won't change practice tomorrow, but it raises some interesting questions about what the ECG may still have to tell us about risk stratification in PE.

So let's get into it!

Face mask ventilation is one of those skills that can easily be overlooked. It's often seen as the simple bit of airway management — something that sits below the glamour of videolaryngoscopy, fibre-optics and endotracheal intubation. But the reality is that excellent face mask ventilation is one of the most important airway skills we have.

In this episode, we take a deep dive into bag-valve-mask ventilation and airway adjuncts, exploring why this is far more than just putting a mask on a face and squeezing a bag. We discuss when facemask ventilation is indicated, how to identify patients who may be difficult to ventilate, and the practical steps that can dramatically improve success rates.

We cover positioning, airway opening manoeuvres, mask seal techniques, the role of airway adjuncts and how to recognise whether your ventilations are actually working. We also look at troubleshooting common problems, the evidence comparing bag-mask ventilation with supraglottic airways and endotracheal intubation, and how to decide when it's time to move to another airway strategy.

Whether you're working in the emergency department, prehospital environment or critical care, this episode is packed with practical tips, cognitive aids and evidence-based advice to help you deliver facemask ventilation with confidence and excellence.

This month's episode takes us deep into trauma care, but not just the medicine we deliver but also the systems, circumstances and social factors that shape who survives and who doesn't.

We start by looking at a remarkable paper from Gaza describing the use of ultrasound-guided pericardiocentesis, large-bore drainage and intrapericardial tranexamic acid as definitive management for penetrating cardiac tamponade. In a setting where immediate thoracotomy simply wasn't always possible, the authors report some pretty incredible survival figures and challenge a lot of the dogma around penetrating cardiac injury. It's a fascinating example of innovation being driven by necessity.

We then move onto a huge epidemiological study from the London Trauma System exploring when and where trauma deaths occur in a mature major trauma network. The findings are stark — most deaths now occur before hospital arrival, often within minutes, and many from potentially reversible causes. It really makes us think about where the next advances in trauma care need to happen.

Finally, we finish with an incredibly important and sobering paper examining knife-related deaths in children and young people across England. This isn't just about anatomy and interventions — it's about deprivation, adverse childhood experiences, safeguarding and public health. It's a paper that's difficult to read at times, but absolutely essential for anyone involved in emergency and prehospital care.
