Vascular access in the neonate

Up to recently, inserting venous or arterial ‘lines’ in the neonate was essentially based on clinical skill and experience. The recent advent of portable ultrasound (US) machines with paediatric probes has resulted in the development of new approaches that, if correctly learned and used, should allow quicker and safer vascular access in this population. Both classic and new techniques are reviewed on the basis of literature and authors’ experience. Live illustrations are freely available at www.
