The Ability of Anesthesiologists Identifying Internal Jugular Vein Bilaterally by Anatomic Landmarks

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

22 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

the residents of anesthesiology clinics

Description

Inclusion Criteria:

  • The voluntary anesthesiologists who are studying in diskapi training and research hospital

Exclusion Criteria:

  • The anesthesiologists who are not willing to participate, the anesthesiologists whom refused to fulfill the questionnaire form.

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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 the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
determine the difference between anesthesiologists ability to show left and right internal jugular vein by usg probe (pass/fail)
Time Frame: participants will be followed for the duration of operating room stay, an expected average of 15 minutes
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.
participants will be followed for the duration of operating room stay, an expected average of 15 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
determine the difference between senior and junior anesthesiologists ability to show left and right internal jugular vein by usg probe (pass/fail).
Time Frame: participants will be followed for the duration of operating room stay, an expected average of 15 minutes
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.
participants will be followed for the duration of operating room stay, an expected average of 15 minutes

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2012

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
