# The role of tele‐ultrasound for real‐time remote guidance for femoral nerve blocks in the emergency department

## TL;DR

This paper introduces a tele-ultrasound framework to enable real-time expert guidance for femoral nerve blocks in emergency departments.

## Contribution

The novel contribution is a practical tele-ultrasound protocol for remote procedural assistance in emergency medicine.

## Key findings

- Tele-ultrasound can provide real-time guidance for femoral nerve blocks when experts are unavailable on-site.
- The framework enhances accessibility and ease of expert support during ultrasound-guided procedures.
- It addresses the limitations of simulated training for rare or complex procedures.

## Abstract

The use of point‐of‐care ultrasound (POCUS) is integral to the practice of emergency medicine, particularly for procedural guidance. While simulated repetitions can aid in educating physicians in rare or difficult procedures, they cannot replace the need for real‐time supervision and guidance especially when a learner is performing a procedure on a patient for the first time. However, procedural experts may not be immediately available in many clinical environments. We present a framework for a tele‐ultrasound protocol for use with femoral nerve blocks in which expert proceduralists can be readily available to assist with ultrasound‐guided procedures with ease and accessibility.
