Ep 101 - November 2017 Round Up

Reflections from November: Key Discussions on Triage, TXA, and Challenges in the ED In November, the St. Emlyns team, led by Natalie May and Simon Carley, explored a variety of critical topics in emergency medicine. These ranged from the complexities of triage in emergency departments to the debated use of tranexamic acid (TXA) and the daily challenges faced by ED professionals. This post encapsulates the key discussions, insights, and upcoming events that shape our understanding and practice in emergency medicine. Triage in Emergency Medicine: Beyond Categorization Laura’s post on triage revisited its historical origins, particularly Dominique Jean-Larry's battlefield practices. Traditionally, triage involves categorizing patients by the severity of their conditions. However, Laura emphasized a crucial, often overlooked aspect: prioritizing patients based on actionable interventions. This approach challenges us to consider not just the severity of conditions but the potential impact of timely treatments. This nuanced perspective is particularly relevant in pediatric trauma triage, where no existing tools perfectly balance sensitivity and specificity. The discussion raised an essential question: In major incidents, should we prioritize resources for patients with severe but untreatable injuries, or those with treatable conditions at risk of deterioration? The post also addressed the unrealistic diagnostic expectations placed on triage systems. For example, can triage systems accurately distinguish between a tension pneumothorax and a panic attack? This issue highlights the importance of understanding the specific purposes for which triage tools are designed. For instance, the Manchester Triage System (MTS) was not intended to predict ICU admissions or sepsis but to prioritize immediate care needs. The Cath Lab Debate for Out-of-Hospital Cardiac Arrests A significant debate in emergency medicine revolves around the management of patients without ST-segment elevation myocardial infarction (NSTEMI) after out-of-hospital cardiac arrest. A meta-analysis reviewed whether these patients should be directly taken to the cath lab. While findings indicated a potential reduction in mortality, the decision to proceed with angiography must be nuanced. Simon Carley noted that not all patients benefit from immediate cath lab access, especially when the issue might be electrical rather than structural. In Sydney, the two-tier trial leans towards early cath lab interventions, even prioritizing them over initial CT scans in suspected subarachnoid hemorrhage cases. This proactive stance contrasts with more conservative approaches in other regions, highlighting the importance of tailored patient care. The discussion emphasized the need for collaboration with cardiologists to determine the best course of action based on the patient's clinical presentation and suspected pathology. This careful selection process ensures that patients receive appropriate and potentially life-saving interventions. Tranexamic Acid (TXA) in Trauma: Timing Matters The use of tranexamic acid (TXA) in trauma care remains a critical topic. A recent reanalysis of TXA trials underscored that earlier administration is linked to better outcomes, particularly in reducing mortality due to bleeding. The CRASH-2 trial supports the early use of TXA, particularly within three hours of injury, for its anti-fibrinolytic effects. However, concerns about "mission creep"—where TXA is administered to all trauma patients regardless of bleeding risk—were raised. The St. Emlyns team advocates for a more selective approach, administering TXA primarily to patients likely to require blood transfusions. This strategy not only aligns with evidence-based practices but also prevents unnecessary treatment and optimizes resource use. Coping with Challenges in the Emergency Department Janos Baynham addressed the increasing pressures in emergency departments, highlighting how growing patient
