Comparing 1st Pass Success Rate and Number of Attempts for Internal Jugular Vein Cannulation by USG Guided Approach: Short Axis versus Long Axis Technique

The study was carried out in 80 patients admitted in ICU and OT at IGMC Shimla. Patients were divided into 2 groups:- group A (short axis) and group B(long axis) of 40 patients each. Internal jugular vein cannulation was done under USG guidance using the two techniques. We were successfully able to cannulate all the patients. We obtained vascular access with higher first pass success and less number of needle passes using short axis approach compared to long axis.

Comparing Time Taken for Cannulating Internal Jugular Vein by USG Guided Approach: Short Axis versus Long Axis Technique

We have conducted our study in 80 patients admitted in the general ICU, requiring internal jugular vein cannulation. We formed 2 groups of 40 patients each that is:- Group 1 (short axis) and Group 2 (long axis). Under USG guidance, we cannulated the internal jugular vein with short axis view in group 1 and long axis view in group 2. Meanwhile the time taken to perform these cannulations was noted and then compared. After the study, we found that the internal jugular vein was cannulated much faster in short axis group as compared to the long axis group.
