The St.Emlyn’s Podcast

As the UK enjoys its unpredictable summer, with everything from sunshine to hailstorms, we bring you a mix of updates and discussions on emergency medicine, blog content, upcoming conferences, and insightful research reviews. So, whether you're basking in the sun or sheltering from the rain, sit back and enjoy our latest insights into the world of emergency medicine.

In this round-up of Month Year, we talk about a wide range of issues relating to emergency medicine, including nebulised ketamine for analgesia in the ED, risky intubations, presentation skills, more about the DOSE VF trial and analysis of the much-hyped PREOXI trial about preoxygenation before tracheal intubation.

We're excited to announce our participation in two upcoming conferences. The Tactical Trauma Conference in Sweden this October promises to delve into pre-hospital emergency medicine, offering sessions from renowned speakers. It's a fantastic opportunity to learn and network, with flights to Sweden being relatively affordable. The event takes place just north of Stockholm, providing a chance to explore the beautiful city.

In March next year, we look forward to the Incrementum Conference in Murcia, Spain. This is a significant event as emergency medicine has recently been recognized as a specialty in Spain. The conference will feature an impressive lineup of speakers from the FOMED world, including Scott Weingart, Ken Milne, Hany Malamatt, and Slim Resie , among others. Our very own Simon Carly will also be presenting. We'll be there to conduct interviews and gather exclusive content for our listeners.

In this podcast from the PREMIER conference 2024, Francesca Stedman, a consultant paediatric surgeon from Southampton Children's Hospital discusses the care of the child who has ingested a button battery. 

Button batteries are ubiquitous and come in various types and sizes. There are about 85 different kinds available or in use in the UK alone, found in everything from toys to hearing aids. The most notorious is the CR2032, which is about 20 millimeters in diameter and 3.2 millimeters thick. It contains lithium manganese oxide, and while its small size makes it convenient for electronics, it poses a significant risk if ingested.

The danger with button batteries lies in their potential to cause severe injuries when lodged in the esophagus. They can cause necrosis, which is essentially tissue death, due to a strong alkaline substance produced by the battery. This substance acts like a potent oven cleaner, rapidly causing damage. The esophagus has three natural narrowing points where these batteries often get stuck, increasing the likelihood of injury. The situation becomes critical very quickly, often within two hours of ingestion.

One of the most concerning aspects of these incidents is that button battery ingestions are rarely witnessed. Children might present with vague symptoms like drooling, difficulty swallowing, or even just being generally unwell. These can easily be mistaken for other common illnesses, leading to delays in diagnosis. In one particularly harrowing case, a child presented multiple times with symptoms of a respiratory infection, only for an x-ray to reveal a button battery lodged in the esophagus. By then, the damage was extensive.

When ingestion is suspected, immediate action is crucial. Getting a chest x-ray is the first step, and if necessary, a lateral x-ray can confirm the presence of a button battery by revealing a characteristic double rim or halo sign. Pre-hospital measures can include giving honey or jam, depending on the child’s age, to help mitigate the damage. However, these should never delay getting the child to the hospital.

Once at the hospital, the primary goal is to remove the battery as quickly as possible to prevent further injury. Depending on the location of the battery and available specialists, either ENT surgeons or paediatric surgeons may perform the removal. Post-removal care involves monitoring for complications like perforations or fistulas, which can develop days or even weeks later. In severe cases, these injuries can lead to life-threatening conditions, such as aorto-esophageal fistulas, which require immediate surgical intervention.

In summary, button battery ingestion is a serious and often underappreciated risk. Even in homes where precautions are taken, accidents can happen. The key is quick recognition and action. As parents and caregivers, we need to be vigilant about keeping these small, dangerous objects out of children's reach. And if an accident does occur, immediate medical attention is essential to minimize the risk of serious injury.

In this St. Emlyn's podcast, Rick Body and Greg Yates, continue our exploration of diagnostic test accuracy, shifting our focus to positive predictive value (PPV) and negative predictive value (NPV). These concepts are vital for anyone preparing for exams or looking to enhance their application of diagnostic tests in clinical practice. While our last podcast discussion centred on sensitivity and specificity, PPV and NPV offer a different, arguably more clinically practical perspective on interpreting test results.

Positive predictive value (PPV) and negative predictive value (NPV) are essential tools for understanding the effectiveness of diagnostic tests. PPV helps us determine the likelihood that a patient with a positive test result actually has the condition, whereas NPV helps us gauge the probability that a patient with a negative test result does not have the disease. These values are crucial for making informed clinical decisions, particularly when considering the prevalence of a condition in the population. Today, we’ll delve into these concepts, their practical applications, and why it's important to consider both PPV and NPV alongside sensitivity and specificity.

In today's episode, taken from live recordings at PREMIER 2024, we dive into an increasingly common treatment for type 1 diabetes: hybrid closed loop insulin pumps. We'll begin with a brief overview of traditional insulin pumps and explain how hybrid closed loops are different. The core of our discussion will be centered around three case studies, illustrating potential scenarios you might encounter in a pediatric emergency department and how to manage them effectively.

With NICE's recent technology appraisal advocating for universal access to hybrid closed loop systems for all type 1 diabetes patients, it's crucial to understand these devices. Over the next few years, you'll likely encounter these systems frequently. We'll cover the essentials of how these pumps work, their benefits, and potential issues that might arise, such as connectivity problems, cannula issues, and handling intercurrent illnesses.

Join us as we explore the revolutionary impact of hybrid closed-loop systems, which offer better glucose control and significantly improve the quality of life for those with type 1 diabetes.

It was a huge pleasure to sit down with Steve Smith, a name synonymous with ECG expertise. Steve, renowned worldwide for his influential ECG blog, has been a pivotal figure in advancing our understanding of ECGs. Many of us have honed our ECG skills thanks to Steve’s insights. I had the opportunity to meet Steve about a decade ago at one of the SMACC conferences. Today, we delve into the fascinating world of occlusive myocardial infarction (OMI) and its comparison to STEMI (ST-elevation myocardial infarction), and explore the promising future of artificial intelligence in ECG interpretation.

In this special episode of the St Emlyn's podcast, we explore the concept of occlusive myocardial infarction (OMI) and its distinctions from ST elevation myocardial infarction (STEMI). Dr. Smith discusses his extensive work and experience in emergency medicine, spanning over three decades, and his development of Dr. Smith's ECG blog. The conversation dives into the limitations of traditional STEMI criteria and the benefits of adopting the OMI paradigm. Additionally, they discuss the revolutionary potential of artificial intelligence in ECG interpretation, particularly through the Queen of Hearts program developed in collaboration with Powerful Medical. Dr. Smith shares compelling studies and real-world applications demonstrating the efficacy of AI in diagnosing ECGs, ultimately offering a promising future for enhanced patient outcomes.
