Short cannulas are inserted by direct venipuncture, with or without the aid of visualization by NIR technology (Near Infra-Red).
24G or 26G agocannules are used. Polyurethane cannula with pre-assembled extension and wide soft wing will have chances of longer duration.
The choice of the superficial vein to be cannulated will be guided preferably by the RaSuVA protocol, which involves a systematic examination of the superficial veins of the newborn, from the foot to the head, first on the right side and then on the left side, evaluating the seven sites where it is more likely to identify a vein: (1) medial malleolus, (2) lateral malleolus, (3) retro popliteal area, (4) hand and wrist, (5) antecubital area, (6) preauricular zone, (7) post-auricular zone.
