Introduction:
Emergent umbilical venous catheter (eUVC) insertion is the recommended vascular access in neonatal resuscitation. Although the theoretical knowledge can be taught, existing models are either unrealistic (plastic) or train only the steps of the task. This study aimed to develop and test a hybrid simulator for eUVC insertion training that would be realistic, reproducible, easy to build, and inexpensive, thereby facilitating detailed learning of the procedure.
Methods:
Development took place in the Poitiers simulation laboratory using a neonatal mannequin into which a real umbilical cord was integrated. In the first phase, pediatric and emergency physicians and residents tested the model. In the second phase, another group of participants tested the hybrid simulator and the same neonatal mannequin associated with an artificial umbilical cord. Participants completed a satisfaction survey.
Results:
A real umbilical cord connected to an intra-abdominal reservoir containing artificial blood was added to the mannequin, allowing insertion of the eUVC, drawback of blood, and infusion of fluids using the real anatomical structures. The model was easily reproduced and assembled in less than 30 minutes; the cost of construction and use was evaluated at €115. One hundred two participants tested the model, 60 in the first phase and 42 in the second. The success rate was higher in fully trained compared with untrained participants. All were satisfied, 97% found the model realistic, and 78.6% strongly recommended the use of this model. The participants believed that the hybrid simulator allowed better learning and a gain in performance and self-confidence in comparison with the same mannequin with an artificial umbilical cord.
Conclusions:
A hybrid simulator was developed for eUVC insertion. Participants were satisfied with this model, which was realistic, reproducible, easy to use, inexpensive, and facilitated an understanding of the anatomy and performance of all steps for successful eUVC insertion.
