Ultrasound Guided Central Venous Catheterization: Seldinger vs. Modified Seldinger Technique

Summary

The investigators intend to compare the Seldinger technique and modified Seldinger technique on success rate and complications during central venous catheterization by a prospective, randomized, controlled study. The investigators are planning to compare both techniques in both experienced (anesthesiologist board member) and non-experienced practitioners (first and second-grade resident).

Conditions

• Catheterization, Central Venous

Interventions

OTHER

Modified Seldinger technique, Experienced group

This is a technique for central venous catheterization. We will use needle that is covered with guiding sheath. After desired vessel puncture, guiding sheath is instantly slid over the needle into the vessel. The needle is withdrawn, guidewire is advanced through the guiding sheath, central catheter is placed into the vessel. The procedure will be performed by experienced practitioners who are board-certified anesthesiologist staffs and have experience of more than 50 central venous catheterizations in both techniques.

OTHER

Seldinger technique, Experienced group

This is a technique for central venous catheterization. The desired vessel is punctured with a sharp hollow needle, syringe is detached and guidewire is advanced through the lumen of the needle, and then the needle is withdrawn. Central catheter is then passed over the guidewire into the vessel. The procedure will be performed by experienced practitioners who are board-certified anesthesiologist staffs and have experience of more than 50 central venous catheterizations in both techniques.

OTHER

Modified Seldinger technique, Inexperienced group

This is a technique for central venous catheterization. We will use needle that is covered with guiding sheath. After desired vessel puncture, guiding sheath is instantly slid over the needle into the vessel. The needle is withdrawn, guidewire is advanced through the guiding sheath, central catheter is placed into the vessel. This technique will be performed by inexperienced practitioners who are junior residents and have experience of less than 50 central venous catheterizations in both techniques.

OTHER

Long-axis technique

Ultrasound probe is placed parallel to the vessel trajectories and needle is advanced using in-plane approach.

OTHER

Short-axis technique

Ultrasound probe is placed vertical to the vessel trajectories and needle is advanced using out-of-plane approach.
