Wire-in-needle vs. Traditional Technique for Ultrasound-guided Central Venous Catheter Placement

The guidewire will be connected to the needle. The IJV will be punctured in a long-axis in-plane approach. When the needle tip enters the IJV, the guidewire will be advanced through the needle into the IJV under continuous ultrasound visualization. The needle will then be removed. The correct guidewire position in the IJV will be confirmed in the long-axis and short-axis view. Afterwards, the second guidewire will be placed in the same IJV approximately 1-2 centimeters distal to the fist guidewire using the same technique. The correct guidewire position in the IJV will be confirmed in the long-axis and short-axis view again.
