I have been doing PICC's for 2 years, just recently learning to use the SiteRite to put them in. I had an excellent blood return and could advance catheter 30 cm but could not maneuver around the shoulder. I tried everything I could think of. MovingÂ arm close to body, 45 degree angle, flushing the catheter, turning head away from the side I was working on. Â Nothing worked. Any suggestions?
