Ergonomics in ultrasound-guided nerve blocks
Introduction: Performing ultrasound-guided nerve blocks has proven to be safe, but ergonomic considerations are essential.
Methods: A non-systematic literature search was conducted in the Medline/Pubmed and Embase databases.
Objective: To describe the influence of operator position, monitor location, and hand position in performing ultrasound-guided nerve blocks.
Results: Poor ergonomics is a key factor of error when performing nerve blocks under ultrasound guidance. "In-plane" needle insertion increases success. An inappropriate position may be a cause of muscle-skeletal disorders. Based on these results, we propose specific element location and operator position for the performance of certain nerve blocks.
Conclusion: Performing ultrasound-guided nerve blocks requires an ergonomic work area allowing for greater comfort and effectiveness, thus reducing the occurrence of muscle-skeletal disorders.
