“Both ultrasound and the Seldinger technique have been shown to improve outcomes during vascular access.1 2 International guidelines recommend ultrasound-guidance when difficulties are encountered or expected.1 3–5 However, difficulties still occur, and a broader array of adjuncts is likely to be useful. I would like to recommend a novel technique using the Vygon Arterial Leadercath polyethylene (PE) kit (Vygon, Ecouen, France) as a coaxial introducer for wider-bore cannula, in cases of difficult intravenous access (DIVA).”Reference:
