研究概览
简要总结
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.
详细描述
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.

研究组 & 干预措施
With nerve track function(group A)
trained in the live demo method with nerve track function
干预措施: Ultrasound with nerve track function (Device)
Without nerve track function(group B)
trained in the existing live demo method without nerve track function
干预措施: Ultrasound without nerve track function (Device)
结局指标
主要结局
Success rate (%) of accurately locating a nerve in the first round in groups A and B
时间窗: 5 minutes after starting to find the nerve using ultrasound
The subjects search for the median nerve and brachial plexus after ultrasound live demo training according to the group. If each nerve is found within 5 minutes, it is considered a success.
次要结局
- Success rate (%) of accurately locating a nerve in the second round in groups A and B(5 minutes after starting to find the nerve using ultrasound)
- Medical students and anesthesiology residents success rate (%)(5 minutes after starting to find the nerve using ultrasound at first round and second round)
- Subjects' assessment of the educational effect of the nerve track function(5 minutes after the second round of finding nerves)
