What’s really new in the field of vascular access? Towards a global use of ultrasound

We read with interest the paper from Schmidt and collaborators reviewing the advantages of ultrasound in central venous access (CVA) . However, modern ultrasound application in the field of CVA is not limited to ultrasound-guided venipuncture but it can be extended to assist all steps of CVA: (a) rational choice of appropriate vein and proper approach; (b) prevention of malposition; (c) ruling out of respiratory complications .
Most benefits of ultrasound-based CVA come from a preliminary evaluation of all possible venipuncture options which allows a rational choice of the most appropriate vein to cannulate, considering such factors as vein size, pathological abnormalities, and collapse during breathing . In a critical care environment, two long-term outcome determinants are of paramount importance: (a) vessel and approach should be chosen so as to obtain an exit site allowing optimal management and dressing to reduce catheter-related infections and accidental...
