Rapid Superficial Vein Assessment (RaSuVA): A pre-procedural systematic evaluation of superficial veins to optimize venous catheterization in neonates.

Background: Placement of peripheral intra-venous cannulas and epicutaneo-caval catheters is routinely performed in in Neonatal Intensive Care Unit (NICU), and both devices require visible superficial veins easy to cannulate. NICU patients are intrinsically characterized by poor and fragile vein asset, so that puncture and cannulation of superficial veins is often a challenge even for trained clinicians and cannulation frequently results in a stressful, painful, difficult procedure.

Methods and results: Rapid Superficial Vein Assessment is meant to offer a systematic pre-procedural evaluation of all superficial veins of the newborn, so to allow a rational choice of the best insertion site, tailored on the single patient, and optimized for the specific type of venous access device. The superficial veins are examined systematically, both with and without NIR technology, exploring seven skin areas in the following order: (1) medial malleolus, (2) lateral malleolus, (3) retro-popliteal fossa, (4) back of the hand and wrist, (5) antecubital fossa, (6) anterior scalp surface, and (7) posterior scalp surface.

Conclusions: The aim of the protocol is to increase the first attempt success rate and reduce the duration of the procedure, the number of attempts for single patient and possibly to limit complications, stress, and pain in neonates.
