Details and patient eligibility

About

Seldinger technique is a minimally invasive technique in which the practitioner accesses the target vessel with a small bore needle, then dilates to the size required for the catheter. Contrarily, modified Seldinger technique(guiding sheath-over-the-needle technique) use needle that is covered with guiding sheath.

Both technique is widely used in central venous catheterization, however, few researches have been investigated to compare success rate or complications of both methods.

Full description

The major complications of central venous catheterization through subclavian vein, are unintended arterial puncture, pneumothorax, hemothorax, malposition of catheter etc,. We assume that using modified Seldinger technique (MST), guiding sheath is easily slid over the needle, providing stable route into the vessel lumen relatively.

We aimed to compare the Seldinger technique and modified Seldinger technique(MST) on success rate and complications during subclavian central venous catheterization in this prospective, randomized , controlled trials.

Enrollment: 418 estimated patients

---

418 participants in 2 patient groups

GroupC

Active Comparator group

Description:

Group C means Control group which use Seldinger technique for subclavian catheterization. The aimed vessel(subclavian vein) is punctured with a sharp hollow needle, syringe is detached and guidewire is advanced through the lumen of the needle, and the needle is removed. After that catheter is passed over the guidewire into the vessel.

Treatment:

Procedure: Seldinger technique

Group MS

Experimental group

Description:

Group MS means experimental group which use modified Seldinger technique for subclavian catheterization. The aimed vessel is punctured with the needle that is covered with guiding sheath. After vessel is punctured, guiding sheath is instatntly slid over the needle into the vessel. The needle is removed, guidewire is advanced through the sheath, central catheter is placed into the vessel.

Treatment:

Procedure: Modified Seldinger technique
