Efficacy of Simulation-based Neonatal Echocardiography Training (SimuEchoNeo)

Echocardiographic examination plays a critical role in neonatology, but its bedside training faces challenges due to limited patient access. While simulation training has proven effective in different fields of adult medical care, its application in neonatal echocardiography remains unexplored. Researchers will compare simulation-based training to usual training (theorical and bedside) for neonatal echocardiography among pediatric residents to see if simulation-trained residents have better skills. Participants will undergo : * theorial, simulation-based and bedside training or * theorical and bedside training only.
