Site Rite from Bard does NOT require the Seldinger technique. Can be used prior to stick to locate the vein or mid-procedure to locate vein & your needle. Needle guides are then not used & the sterile sleeves are $65./box of 10 vs $120./box with needle guides.
I am the vascular nurse for our 160 bed community hospital. I place 30-40 Midlines or PICCs per month; central line care; difficult sticks and am resource person. The Site Rite, ultrasound from Bard, has significantly increased my success rate with Mids & PICCs.
