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.

| UGIJVC with needle guide device | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | Within 2 minutes or after start to insertion attempt |
| Measure | Description | Time Frame |
|---|---|---|
| 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) | Within 2 minutes or after start to insertion attempt |
