St Emlyn’s is a long-standing online resource for emergency medicine and critical care, created by a team of UK clinicians based in Manchester. The project includes a blog, podcast, and teaching materials, all focused on sharing high-quality, evidence-informed insights from the frontline of acute care.
The podcast is hosted by Prof Simon Carly and Dr Iain Beardsell.
Tactical trauma decisions balance incomplete information, scene danger and harmful delays. The 40–70 rule, 10 Second Triage Tool and difficult decisions about eCPR or trauma ECMO illustrate the importance of practical triage, patient selection and shared clinical reasoning.
Chest-pain character, cardiovascular risk-factor counts and clinical judgement cannot reliably exclude myocardial infarction on their own. Detailed history should seek a convincing explanation, with troponin testing when symptoms remain unexplained and myocardial infarction is still plausible.
In traumatic cardiac arrest after penetrating injury, wound location and presenting ECG rhythm help distinguish tamponade from exsanguination and guide treatment; organised electrical activity can persist, and an unreliable arrest-time report should not automatically exclude resuscitative thoracotomy.
Myocardial infarction classification separates primary, secondary and procedure-related disease while distinguishing infarction from acute or chronic myocardial injury; sex-specific troponin limits, symptom timing, sampling intervals, mechanism and imaging all influence the final diagnosis.
Trauma care requires direct pressure at the actual bleeding point, physiology-led decisions about chest drainage before CT and deliberate transfer preparation, while systems thinking and critical appraisal help avoid simplistic responses to crowding, smoking cessation and pulmonary embolism evidence.
Structured pulmonary embolism risk assessment should precede D-dimer testing or CT pulmonary angiography, while echocardiography mainly informs severity after diagnosis. The wider evidence review separates operational promise from outcome benefit in whole-blood transfusion, highlights unequal helicopter emergency medical service access, and examines physiology-guided resuscitation and selective tamponade drainage.
Emergency, critical-care and medical-education clinicians get a practical discussion of how expertise develops. Mental models, deliberate practice, feedback, safe simulated failure, a three-bucket cardiac-arrest differential and pause-bookmark-refocus task switching are linked to better reasoning under pressure.
Emergency and trauma teams get practical material on trauma CT interpretation, post-CT team leadership and safer patient movement. Rapid preliminary reports are framed as an imaging primary survey, while minimal-movement log rolling and specific positive feedback support safer trauma workflow.
Pre-hospital, HEMS and clinical leadership teams get a culture-focused episode on expert teams, psychological safety and sustainable service development. It links inclusive meetings, quieter voices, private feedback, difficult conversations, delegation, charity partnership and marginal gains to better trauma care.
Several emergency medicine arguments sit inside this round-up, but the clearest bedside point is code red activation. Trigger it from active bleeding and shock physiology rather than waiting for certainty, then read the RSI paper from its primary mortality outcome before changing practice.
