A randomised controlled trial of intracavitary electrocardiography versus traditional anthropometric guidance for central venous access device placement

This study has shown that the method of ECG guidance to place central venous catheters is more accurate and efficient than traditional bedside methods. The technique can be used across diverse patient populations requiring a wide range of devices. The ECG technique saves procedural time and allows the catheter to be used immediately after insertion, as such contributing to significant direct and indirect cost savings, as well as providing patient safety benefits by reducing the reliance on x ray confirmation and therefore limiting radiation exposure.
