Real vs simulated umbilical cords for emergency umbilical catheterization training: a randomized crossover study.
1Division of Neonatology, Seattle Children's Hospital, University of Washington School of Medicine, Seattle, WA, USA.
Summary
Pediatric residents preferred the real cord (RC) model over the simulated cord (SC) for emergency umbilical vessel catheter (eUVC) insertion training due to higher fidelity, despite longer procedure times with the RC model.
Area of Science:
- Medical Simulation
- Pediatric Emergency Medicine
- Medical Education
Background:
- Effective simulation models are crucial for training emergency umbilical vessel catheter (eUVC) insertion.
- Evaluating the performance, fidelity, and user preference of different eUVC simulation models is essential for optimizing training.
Purpose of the Study:
- To compare the performance, physical and functional fidelity, and user preference between a real cord (RC) and a simulated cord (SC) model for eUVC insertion.
Main Methods:
- A randomized crossover trial involving senior pediatric residents.
- Participants performed eUVC insertion using both RC and SC models.
- Procedure times were recorded, and participants rated the fidelity and preference for each model.
Main Results:
- The real cord (RC) model demonstrated higher physical and functional fidelity compared to the simulated cord (SC) model.
- Pediatric residents expressed a preference for the RC model for training.
- While initial eUVC placement times were slower with the RC model, this difference diminished when participants used the SC model first.
Conclusions:
- The real cord (RC) model is preferred by pediatric residents for eUVC insertion training due to its superior fidelity.
- Despite longer placement times, the enhanced fidelity of the RC model makes it a valuable training tool.
