Background: Central venous access and nerve blockade are essential skills in the practice of emergency medicine, and the utility of emergency ultrasound to guide these procedures has been well demonstrated.
Methods: A phantom is a valuable tool to learn and develop the dexterity for ultrasound-guided techniques.
Results: To date, the time and cost required to produce or purchase such models has somewhat limited their use.
Conclusion: A time- and cost-effective alternative using polony and common household items is presented.
