Point-of-care ultrasound is a rapidly expanding field in emergency medicine, offering significant potential to improve the quality and safety of care without necessarily increasing costs. While the majority of doctors have integrated this technique into their practice to strengthen their clinical decision-making, nurses working in emergency facilities could also benefit from this technology, whether they are registered nurses (Infirmière diplomée d’état; IDE) or advanced practice nurses (Infirmière en pratique avancée; IPA). In countries outside France, the use of this technique is already a reality, with tangible evidence of improved patient management. In registered nurse care, peripheral venipuncture has proven effective in difficult cases, and other diagnostic techniques are enhancing clinical relevance and monitoring. Among advanced practice nurses, the use of diagnostic techniques seems to improve clinical relevance. These data underscore the need for emergency departments to seriously consider integrating this technique into routine practice. A key obstacle to widespread implementation is the need for adequate training. For nurses to be able to use ultrasound effectively in their practice, they need to receive appropriate training. This will require a decision on how training institutions and programs can adapt to this essential evolution.
