Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• processing time

  The technique to be used will be determined according to the randomization performed. The procedure time will begin at the moment of the first needle insertion (syringe or catheter needle) after skin cleansing and will end at the placement of the jugular catheter without suturing.

  The procedure time is expected to be 30% shorter with the syringe-free technique. Catheter insertion is expected to take around 120 seconds.

Study Arms (2)

with a syringe

EXPERIMENTAL

Central catheterization of the jugular vein will be performed using the Seldinger method (first inserting a guide wire, then placing the catheter over it) with ultrasound guidance and an out-of-plane technique. A guide needle attached to a syringe will be inserted into the vein to aspirate blood, and then a catheter will be placed over the wire sent into the vein through the needle. This procedure will be performed under ultrasound guidance, visualizing the veins, guide wire, and needle.

Procedure: out-of-plane technique

syringe-free technique

ACTIVE COMPARATOR

In the syringe-free technique, a guide wire will be placed inside the needle and sent directly into the vein. In this technique, central jugular vein catheterization will be performed using the Seldinger method (using a guide wire) with an in-plane approach (visualizing the entire needle and vein longitudinally). There is no need to draw blood into a syringe to confirm that the needle is in the vein.

Procedure: in-plane technique

Interventions

ultrasound-guided out-of-plane technique for central venous catheterization

with a syringe

in-plane technique PROCEDURE

In the syringe-free technique, a 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 its presence in the vein. Using ultrasound-guided in-plane technique (with the entire needle and vein visualized longitudinally), central catheterization of the jugular vein will be performed using the Seldinger method (with a guide wire).
