About this study
Official title: The Ability of Anesthesiologists Identifying Internal Jugular Vein by Anatomic Landmark Technique
The study is designed to determine anaesthetists ability to locate the right internal jugular vein(IJV) and left IJV using a landmark technique. Initially, a questionnaire was completed detecting previous user experience. An ultrasound probe, using the midpoint as an 'imaginary needle', was placed on the neck of a healthy volunteer and the image recorded. Both anaesthetist and volunteer were blinded to the screen until the image was stored. Anaesthetists were grouped into senior or junior by the total number of IJV canulation experience. The success rate is going to be measured as pass or fail.
Read the detailed description
Anesthesiologists are usually qualified in internal jugular vein canulation by using anatomic landmark technique. The anatomy of right IJV and left IJV may differ each other. The hypothesis is that the anatomical difference between right and left IJV may give rise to false puncture of especially left IJV by using anatomical landmark technique.Although USG is available, most of the experienced anesthesiologist does not prefer to use USG for IJV canulation due to different reasons.In addition to this anesthesiologists are generally preferring right IJV canulation, thus they are inexperienced in left IJV canulation. So especially during left IJV canulation,not by anatomical landmark technique but by USG will be recommended for anesthesiologists.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| anesthesiologists, experience | There is one arm. All participating anesthesiologists wıll fulfill the questionary survey and show the imaginary puncture site by USG bilaterally. |
What is being measured
The primary outcome is the main question the study is designed to answer.
determine the difference between anesthesiologists ability to show left and right internal jugular vein by usg probe (pass/fail)
The participants are going to be graded pass/fail according to whether the midline trajectory of the usg probe intersected any part of the lumen of the internal jugular vein. The participating anesthesiologists will show imaginary puncture site for IJV cannulation bilaterally by ultrasonography. The blind investigator will save the ultrasonographic images as jpeg files and another investigator will consider the images.
Measured: participants will be followed for the duration of operating room stay, an expected average of 15 minutes
Secondary outcomes (1)
determine the difference between senior and junior anesthesiologists ability to show left and right internal jugular vein by usg probe (pass/fail).
The participants are going to fulfill a survey asking their experience about IJV canulation. After the survey the anesthesiologists are going to classified as senior/junior. The participants are going to be graded pass/fail according to whether the midline trajectory of the usg probe intersected any part of the lumen of the internal juguler vein.
Measured: participants will be followed for the duration of operating room stay, an expected average of 15 minutes
