An interventional study of UGIJVC with needle guide device and UGIJVC without needle guide device in Doctors Attending a Central Line Insertion Training Courses for New Residents of a University Hospital From March 2017 to June 2017 and Physicians Who Had Less Than 10 Ultrasound Guided Internal Jugular Vein Cannulation Participate in This Study, sponsored by Yonsei University. Completed at 1 site in Korea, Republic of. Open to participants aged 20 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-08-17.

Two-dimensional ultrasound guided approach does not guarantee first attempt success on internal jugular vein cannulation. New attachable device recently was developed for accurate needle insertion when ultrasound is used. Our randomized parallel simulation study will examine whether this device will improve the first attempt success rate when ultrasound guided internal jugular vein catheterization of simulated internal jugular vein.
This was a prospective, randomized, parallel trial using phantom simulating internal jugular vein.
After informed consent all subjects will be randomized to insert needle for internal jugular vein cannulation of phantom using ultrasound approach with or without this device. Video camera will record all procedure process and ultrasound image in real time. Researchers blinded to the study aim measured outcome variables based on recorded images.
Exclusion Criteria:
participants who are tested performance for ultrasound guided cannulation using device
Device: UGIJVC with needle guide device
participants who are tested performance for ultrasound guided cannulation using conventional method
Device: UGIJVC without needle guide device
Study subjects assigned to each group were trained in ultrasound guided internal jugular venous cannulation (UGIJVC) in separate spaces. On each session, subjects were educated about UGIJVC for 30 minutes, and the instructor who was in charge of session, consisted of experienced physicians who had 50 or more UGIJVC success experiences without a supervisor in clinical field. The instructors explained the anatomical structure and the principles of UGIJVC and then demonstrated the procedures directly to the subjects using phantom. After that, all subjects were instructed to perform hands on practice for 30 minutes. In case group, the instructor trained subjects using device. On the other hand in control group, UGIVJC was demonstrated as a conventional method of approaching the target vessel while confirming the needle tip on the ultrasound screen in real time without a device.
participants who are tested performance for ultrasound guided cannulation using conventional method.
Also known as: Conventional group
First attempt success
The first attempt success was defined as a successful attempt to perform a vein puncture in one attempt. The number of attempts was counted each time a subject inserted a guide needle into the phantom surface, followed by withdrawal, redirect, or reinsertion.
Time frame: Within 2 minutes or after start to insertion attempt
Posterior wall puncture of the internal jugular procedure, comfort level with procedure
It was defined when the needle tip on the recorded ultrasound screen was confirmed to pass through the posterior wall measurement unit : Yes or no (categorical variable)
Time frame: Within 2 minutes or after start to insertion attempt
Carotid artery puncture
It was defined as the needle tip passing through the carotid lumen or the subject regurgitating artery water during cannulation attempt. measurement unit : Yes or no (categorical variable)
Time frame: Within 2 minutes or after start to insertion attempt
Time to cannulation
It was defined as the time from time out for procedure start to end point measurement unit : second
Time frame: Within 2 minutes or after start to insertion attempt
Comfort level
It was defined subjective opinion about difficulty during procedure for each subject measurement unit : 100-mm visual analogue scale with 0 being the least of the difficulties and 10 being the highest.
Time frame: Within 2 minutes or after start to insertion attempt
