title: [Ultrasound-guided central venous catheterization - "Syringe-Free" approach].
abstract: OBJECTIVE
  Central venous catheterization of the internal jugular vein is a commonly performed invasive procedure associated with a significant morbidity and even mortality. Ultrasound-guided methods have shown to improve significantly the success of the technique and are recommended by various scientific societies, including the American Society of Anesthesiologists. The aim of this report is to describe an innovative ultrasound-guided central line placement of the internal jugular vein.
  
  
  METHODS
  The authors describe an innovative ultrasound-guided central line placement of the internal jugular vein based on an oblique approach - the "Syringe-Free" approach. This technique allows immediate progression of the guide wire in the venous lumen, while maintaining a real-time continuous ultrasound image.
  
  
  CONCLUSIONS
  The described method adds to the traditional oblique technique the possibility of achieving a continuous real-time ultrasound-guided venipuncture and a guide wire insertion that does not need removing the probe from the puncture field, while having a single operator performing the whole procedure.
