超声引导下外周神经阻滞技术因为精准及安全性高而广泛应用于临床，住院医师掌握该技术必须通过正规培训。但住院医师对神经阻滞相关解剖结构不熟悉、缺乏超声基础知识及操作技巧、欠缺模拟训练、缺少对相应并发症的认识、缺乏局麻药物最佳浓度及剂量；针对上述问题研究组采取了基础理论知识学习、解剖学和超声软件的应用、模拟训练和分级培训等对策，麻醉规范化培训住院医师能充分掌握超声引导外周神经阻滞技术的临床应用。“,”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.
