Ultrasound-guided central venous catheterisation is easier, quicker and safer than the traditional method using landmarks, and should be the method of choice when treating critical care patients. In an article published today in the journal Critical Care, researchers report the results of a prospective randomised controlled trial comparing the use of ultrasound to guide catheterisation to the traditional method using physical landmarks. The researchers report a success rate of 100% for ultrasound-guided catheterisation of the internal jugular vein. They show that the method is less likely to result in blood stream infections or complications, such as puncture of an artery, than the normal catheterisation procedure.
