Validation of Educational Effect of Nerve Tracking Function Mounted on the Ultrasound

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: With nerve track function(group A)<br>trained in the live demo method with nerve track function | Device: Ultrasound with nerve track function<br>* The nerve track function installed in some ultrasound devices is software that accumulates ultrasound data obtained from humans and uses ultrasound to identify the target nerve through deep learning. Well-trained pain physicians use this feature to educate subjects before seeking brachial plexus and median nerve.<br>|
| Active Comparator: Without nerve track function(group B)<br>trained in the existing live demo method without nerve track function | Device: Ultrasound without nerve track function<br>* The nerve track function installed in some ultrasound devices is software that accumulates ultrasound data obtained from humans and uses ultrasound to identify the target nerve through deep learning. Well-trained pain physicians use ultrasound alone without this feature to educate subjects before seeking brachial plexus and median nerve.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Success rate (%) of accurately locating a nerve in the first round in groups A and B | 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. | 5 minutes after starting to find the nerve using ultrasound | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Success rate (%) of accurately locating a nerve in the second round in groups A and B | After completing a first round of finding nerves, the subjects are trained using the nerve track function common to both groups, and are then asked to find nerves again. It is considered a success if each nerve is found within 5 minutes. | 5 minutes after starting to find the nerve using ultrasound | 
| Subjects' assessment of the educational effect of the nerve track function | After completing all the procedures, the subjects expressed their satisfaction with the educational effect of nerve track function on a 5-point Likert scale. Participants will be asked to use a 5-point Likert scale, ranging from 1 to 5, for their responses. Regarding the assessment of nerve track function, the scale is explained as follows: 1 point representing not at all helpful, 2 point representing slightly helpful, 3 point representing neutral, 4 point representing somewhat helpful, and 5 point representing very helpful. | 5 minutes after the second round of finding nerves | 
| Medical students and anesthesiology residents success rate (%) | Among the subjects, the success rate was calculated by dividing the students of the medical school and the residents of the department of anesthesiology. Similarly, finding a nerve within 5 minutes is considered a success. Each round is calculated separately. | 5 minutes after starting to find the nerve using ultrasound at first round and second round |
