Study on Application of Simulated Training in Ultrasound Guided Transversus Abdominis Plane Block

Study Overview
=================
Brief Summary
-----------------
With the development of society and the enhancement of people's awareness of law and self-protection, it is necessary to use simulation technology to create a simulated human and clinical environment to replace the traditional teaching of clinical operation on real patients. So simulation teaching is more and more important in medical education. However, simulation teaching is in the ascendant in China, especially in the ultrasound-guided nerve block, limited by the lack of full simulation of puncture model, the simulation training of ultrasound-guided nerve block is not carried out much. Therefore, this study uses simulation training to carry out ultrasound-guided horizontal abdominal muscle block teaching, in order to explore an effective way of ultrasound-guided nerve block teaching.
