RAVESTO tool for complex vascular access patients

Abstract:

In the last decade, different standardized protocols have been developed for a systematic ultrasound venous assessment before central venous catheterization: RaCeVA (Rapid Central Vein Assessment), RaPeVA (Rapid Peripheral Vein Assessment), and RaFeVA (Rapid Femoral Vein Assessment). Such protocols were designed to locate the ideal puncture site to minimize insertion-related complications. Recently, subcutaneous tunneling of non-cuffed central venous access devices at bedside has also grown in acceptance. The main rationale for tunneling is to relocate the exit site based on patient factors and concerns for dislodgement. The tool we describe (RAVESTO-Rapid Assessment of Vascular Exit Site and Tunneling Options) defines the different options of subcutaneous tunneling and their indications in different clinical situations in patients with complex vascular access.
