A Low-Fidelity, High-Functionality Ultrasound-Guided Serratus Plane Block Model.

BACKGROUND

Thoracic injuries present many challenges for management in the acute and inpatient settings, including achieving appropriate pain control. Traditional modalities, such as opioids and spinal epidural anesthesia, are associated with multiple complications. Ultrasound-guided regional nerve blocks are becoming more prevalent, and they have been shown to be an effective modality of pain control for other traumatic injuries. Models comprised of animal tissue to simulate human anatomy are widely utilized to facilitate training of needle-guided procedures, but no such model for the serratus anterior plane block has yet been defined in the literature.

OBJECTIVES

Our goal was to produce a high-functionality serratus anterior plane block model with reasonable anatomic fidelity from low-cost materials.

DISCUSSION

We describe the creation of an inexpensive high-functionality serratus anterior plane block model from common materials, including pork ribs and chicken breasts, to realistically simulate human anatomy, including multiple muscle and fascial planes, as well as to allow hydrodissection.

CONCLUSIONS

This model will facilitate training and can improve success when caring for patients with thoracic trauma.
