October 2025; papers of the month

This podcast episode centers on critical appraisals of recent research papers relevant to emergency medicine and resuscitation. The first paper examines the feasibility and value of arterial line placement during cardiac arrest in the emergency department, highlighting its potential for improved ROSC detection, while noting limitations in translating this into improved patient outcomes. The second paper assesses the safety of ketamine as a sole sedative agent for pediatric procedural sedation, finding critical adverse events to be rare. The final paper explores the use of ultrasound for pulse checks during cardiac arrest, suggesting it is faster and more accurate than manual palpation, though implementation challenges exist.
