Formation des infirmiers à la pose de voies veineuses périphériques sous contrôle échoguidé : mise en place et évaluation d’un atelier de simulation au CHU de Guadeloupe

Introduction: The insertion of a peripheral intravenous catheter (PIVC) is a routine clinical procedure. However, it carries risks of complications and can be technically challenging in certain patients. Ultrasound guidance (USG) has been shown to significantly improve the success rate of PIVC insertion, reduce the number of failed attempts, and minimize procedure-related complications. Despite these advantages, training in USG PIVC insertion remains limited among nursing staff. Simulation training is now recognized as an effective educational method for learning USG PIVC. However, the high cost of commercially available models may limit access to this training. This study aims to design a low-cost gelatin-based simulation model and to evaluate its educational effectiveness. Materials and methods: This was a prospective, observational, single-center study conducted at the University Hospital of Guadeloupe. Ten training workshops were conducted between March 18 and 22, 2024. The training program consisted of three modules: a theoretical module covering vascular ultrasound principles, a practical module on ultrasound probe handling; and a hands-on training module for USG PIVC insertion on a gelatin-based model. Results: A total of 51 nurses from anesthesia and intensive care units were voluntarily enrolled. Most had no prior experience with ultrasound-guided peripheral venous catheter (PVC) insertion (53%). At baseline, the success rate of ultrasound-guided PVC insertion was 59%, with a mean procedure time of 73 seconds. Following training, the success rate reached 100%, and the mean procedure time decreased to 45 seconds. The adoption of ultrasound-guided PVC placement was evaluated at 3- and 6-months post-training, showing an increase in clinical practice usage from 53% pre-training to 88.6% at 3 months and 91.9% at 6 months. The training was rated as essential by 67% and useful by 33% of participants. Conclusion: This study suggests that implementing procedural simulation workshops using a low-cost gelatin model may be an effective strategy to enhance nurses’ practical skills in ultrasound-guided peripheral venous catheter insertion.
