Ultrasound-guided peripheral nerve block is widely used in clinical practice because of its high accuracy and safety. Residents must pass formal training to master this technique. However

residents are not familiar with the related anatomical structure of nerve block

and lack of basic ultrasonic knowledge

operation skills

simulation training

understanding of the corresponding complications

the optimal concentration and dose of local anesthetic drugs. In order to solve the above problems

we have taken measures such as basic theoretical knowledge learning

application of anatomy and ultrasound software

simulation training and grading training so that residents in standardized training of anesthesiology could fully grasp the clinical application of ultrasound-guided peripheral nerve block techniques.
