Implementation of a low-cost model for training on ultrasound-guided vascular access

Abstract

Introduction: Vascular access procedures are an essential competency for medical residents, with ultrasound-guided insertion being an effective and safe method. There are numerous simulators for central venous catheter insertion, although many of them are inaccessible for educational institutions.

Objective: To evaluate the implementation of a low-cost model for training in central venous catheter insertion.

Method: A quasi-experimental educational intervention was carried out with resident doctors from the Hospital Regional de Alta Especialidad de Oaxaca

Results: 33 medical residents were trained, 54.5% of whom were male. 72.7% were familiar with the correct technique for placing ultrasound-guided vascular accesses, and 51.5% felt confident to perform this task before the training. Subsequently, 69.7% considered that the model was analogous to human anatomy and 90.9% reported that the device provided a clear ultrasound image of the structures. In addition, 81.8% valued the model as suitable for training residents in the placement of ultrasound-guided vascular accesses.

The design of accessible simulators is crucial in developing countries to increase confidence and speed up the learning curve of the staff in training. Low-cost models would facilitate the acquisition of clinical skills, which would result in an improvement in quality care for health service users.

Conclusions: Our model facilitates this learning without the need for large budgets or an increase in the risk of complications when performing this type of procedures, especially for those with little or no experience in the placement of ultrasound-guided central venous accesses.
