Overview
Brief Summary
The central venous catheterization (central line placement) is the common procedure performed in the intensive care unit. This procedure is performed by percutaneous puncture of so called 'the central vein' and than advancement of the catheter over the guidewire (Seldinger technique). The tip of the catheter is left in the superior vena cava in the vicinity of the right atrium of the heart. Central veins are large veins in the human body passing the blood into the heart.
Typical, clinical indications for the central line placement in the intensive care unit are hemodynamic monitoring, volume monitoring, administration of medications, long-term total parenteral nutrition, access for renal replacement therapy, difficult peripheral catheterization.
There are two methods of the central venous catheterization in terms of visualization. First and older is the blind technique. The operator is locating the anatomical landmarks and then performing the entire procedure blindly by percutaneous puncture. This is called the landmark technique. Second and new is the ultrasound-guided technique. The operator is locating the vein using ultrasonography and then performing the entire procedure under ultrasonographic visualization. The real time ultrasound-guided central venous catheterization became the standard of care in recent years mainly because of safety issues (is regarded as safer than landmark technique)
The catheterization of the axillary vein is not popular procedure in daily clinical practice. But it can be reasonable and safe alternative to others, typically performed central venous catheterizations like the internal jugular vein and the subclavian vein catheterizations.
The main intention of this study is to assess usefulness and safety of the real time ultrasound guided axillary vein catheterization in mechanically ventilated patients admitted to the intensive care unit.

Outcomes
Primary Outcomes
to define venipuncture, catheterization and entire procedure success rates
Time Frame: 24 hours
the venipuncture is defined as perforation of the axillary vein by the needle, the catheterization is defined as the placement of catheter in the final position, the entire procedure success rate is defined as the placement of catheter in the final position without early complications (assessed within 24 hours time frame)
to assess the erly complication rate of ultrasound-guided axillary vein catheterization
Time Frame: 24 hours
pneumothorax, puncture of the axillary artery, hemothorax, heart perforation, catheter malposition, significant arrhythmias, air embolism
Secondary Outcomes
- to assess the correlation between entire procedure success rate and the side of catheterization(2 years)
- to assess the correlation between patients weight, height and depth, diameter of the axillary vein(2 years)
