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.
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.

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.
The aimed vessel is punctured with the needle that is covered with guiding sheath. After vessel is punctured, guiding sheath is instantly slid over the needle into the vessel. The needle is removed, guidewire is advanced through the sheath, central catheter is placed into the vessel.

RECRUITINGMajor complication rate of subclavian catheterization
Compare main complication rates of subclavian catheterization including pnumothorax, hemothorax, arterial puncture, malposition of cathter.
Time frame: intraoperative
primary success rate of subclavian catheterization
Check the number of attempts of needling, guidewire advance, and catheterization in both groups.
Time frame: intraoperative
Total insertion time
Check the total insertion time from skin puncture to confirm the successful catheterization via venous aspiration though catheter lumen.
Time frame: From skin puctuation until confim the successful catheterization anticipated within 3min
