Optimal Neck Angle for Internal Jugular Cannulation

Study Overview
=================
Brief Summary
-----------------
Measurements will be made between the internal jugular vein and the carotid artery using an ultrasound machine as the subjects is asked to move and position his or her neck in various positions. It is hypothesized that by movements of the neck the investigators can maximize the distance between the internal jugular vein and the carotid artery to decrease inadvertent cannulation of the carotid artery to improve patient safety

Detailed Description
-----------------
Patients will be asked to participate in this trial if they are scheduled for surgery and they will have their neck repositioned in several ways using an ultrasound machine to measure the distance between the internal jugular vein and the carotic artery to determine maximal distance in order to insert a catheter prior to surgery

Official Title
-----------------

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Neck Angle Measures<br>Subjects will position his/her neck in order to measure distance between the internal jugular and the carotid artery to determine if there is a maximal distance to target prior to cannulation | Other: Neck Angle<br>* Ultrasound guided measures of the neck of subjects undergoing cardiac surgery who need internal jugular vein cannulated<br>* Other names: Distance;|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Find Optimal Angle for internal jugular cannulation | Is there an angle to position ones neck which maximizes distances of carotid artery and internal jugular. | Approximately 4 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Find Optimal Neck Angle | Using the Ultrasound machine and having the subject position his neck measurements will be taken between the internal jugular and carotid artery to determine what angle may provide the maximal distance in order to safely cannulated the internal jugular | Approx 4 years |
