AbstractIn neonates, infants and young children central venous catheters are of vital importance during surgery as well as postoperative care. The benefit of ultrasonography seems to be very important for vascular access of the internal jugular (IJV), subclavian (SCV), femoral and even peripheral veins. Ultrasound-guided cannulation of the IJV increases the success rate, reduces the time to the successful puncture and decreases the inadvertent puncture of the carotid artery in children in comparison to the landmark-guided technique. Due to compression of the vessel by the approaching needle in neonates transfixing the vein and aspirating blood on withdrawal of the needle may be the preferred technique. The lack of space may prevent ultrasound-guided puncture of the SCV in very low birth weight infants. However, the location of the vein and its patency should always be determined via ultrasound prior to cannulation. After catheterization of the SCV the homolateral IJV is screened by the use of ultrasound to detect wrong guide wire migration. A clear and rapid visualization of visceral pleura movement against the parietal pleura during respiration via ultrasound indicates the absence of pneumothorax after cannulation. In the case of haemodynamic instability, ultrasound should be used to exclude pericardial effusion.
