Evaluating the Safety of Current Intraosseous Needles and the Potential for Age-Based Guidance Using a Large-Scale Pediatric CT/MRI Imaging Study

The study reveals significant age-related variability in the proximal tibia's anatomical dimensions, suggesting that standard 15 and 25 mm intraosseous needles may not reliably achieve optimal placement in pediatric patients. Our findings indicate that the current intraosseous needles may not be as safe as previously thought and support the need to develop improved intraosseous needle designs to enhance safety and therapeutic effectiveness in pediatric emergency care.
