COMPARISON OF CLASSICAL AND SYRINGE-FREE TECHNIQUES IN ULTRASOUND-GUIDED CENTRAL JUGULAR VENOUS CATHETERIZATION

During central venous catheterization, both in-plane and out-of-plane techniques can be used. In the in-plane technique, the entire needle can be visualized with ultrasound. In the in-plane technique with a linear probe, the vessel and needle are visualized longitudinally. In the syringe technique, a guide needle attached to a syringe is first inserted into the vein and blood is aspirated, then the catheter is placed through a wire sent into the vein via the needle. This procedure is performed under ultrasound guidance, visualizing the vessels, guide wire, and needle. In the syringe-less technique, the guide wire is placed inside the needle and sent directly into the vein. In this technique, there is no need to draw blood into the syringe to confirm that it is in the vein. The aim of our study is to compare the two ultrasound-guided techniques in terms of procedure time, number of attempts, and complication rates. We expect the syringe-less technique to have a shorter procedure time, fewer attempts, and a lower complication rate.
