The walk-in wounded, detecting hypofibrinogenemia, and "time is testicle!": April 2025 Primary Survey

<p>Trauma and paediatrics are the themes for this month's collection of papers. Starting off is a review of the effectiveness of prehospital ultrasound in detecting lung injury, with some surprising statistics. Next is a letter on the topic of self-presentation by paediatric patients with major trauma, which is thankfully a rare occurrence. The third paper looks at prehospital testing of trauma patients for  low fibrinogen levels, a condition which can lead to worse bleeding, increased transfusions, and higher mortality. The final paper discusses the worrying topic of delayed presentation with testicular pain, a phenomenon which leads to significantly lower salvage rates. This can arise from lack of information or embarrassment, particularly in younger males.</p> <p> </p> <p>Read the highlights: <a href='https://emj.bmj.com/content/42/4/219'>April 2025 Primary Survey</a></p> <p> </p> <ul> <li><a href='https://emj.bmj.com/content/42/4/256'>Diagnostic accuracy of prehospital ultrasound i...
