A low cost,high fidelity nerve block model

Background

We have constructed a simple, inexpensive simulation model for ultrasound guided nerve blocks. To date there are no low cost, high fidelity models for nerve block simulations. The models that do exist are expensive and vaguely resemble actual anatomy. As ultrasound guided nerve blocks become more common in medical education it is essential to develop better training models to help increase the comfort level of the individual provider and increase the chances for success during live-patient procedures [Anaesth Intensive Care 37: 824-829, 2009].

Methods

The nerve block model was produced with a single pork loin with pressure-injected ultrasound gel through both CAT 5 cable and IV tubing inserted length-wise into the pork loin.

Results

Our nerve block model had a realistic, life-like feel simulating human tissue.

Conclusion

This ultrasound nerve block model was inexpensive with life-like feel allowing resident trainees to develop more confidence and tactile skill to increase the chance for success.
