Validation of Educational Effect of Nerve Tracking Function Mounted on the Ultrasound: A Randomized Comparative Trial
Validation of Educational Effect of Nerve Tracking Function Mounted on the Ultrasound: A Randomized Comparative Trial
The purpose of this study is to find out whether the nerve track function is helpful in distinguishing appropriate anatomical structures for beginners using ultrasound.
2nd, 3rd, 4th year medical school students and 1st, 2nd, 3rd year residents of anesthesiology who voluntarily signed a consent form for participation in the study are investigated for the history of previous ultrasound use and other details of the subjects before the lecture and ultrasound practice.
Well-trained pain physicians provides anatomical education on the brachial plexus supraclavicular level and the median nerve at wrist level. At this time, an ultrasound cross-sectional image of the corresponding nerve is provided. After anatomical education, research subjects (students and residents) are randomly assigned to group A or B after receiving basic education in a 1:1 ratio.
Subjects receive training for about 10 minutes to find the brachial plexus (supraclavicular level) and median nerve (carpal tunnel level) through a live demo method that directly uses ultrasound. At this time, group A receives training in the live demo method with the nerve track function, and group B receives training in the live demo method without the nerve track function.
After a 5-minute intermission, both groups A and B were asked to find the brachial plexux and median nerve without the nerve track function in the instructor's left upper limb. Each nerve is to be found within 5 minutes, and it is considered a failure after 5 minutes.
After activating the nerve track function in both groups without intermission, the educator shows the nerves corresponding to the brachial plexus at supracalvicualr level and median nerve at wrist level in the left upper limb, and conducts the same 5-minute training on finding them.
After a 5-minute intermission, with the nerve track function turned off again, ask the educator to find the brachial plexus and median nerve in the right arm.
