Ok well I had to run it peripherally, didn't feel comfortable with it, but the MD said to. It ran for a good 48hrs plus. One site where it was running, has become reddened, hot, and sore to the touch. One nurse said this will become necrotic and slough off. I switched the IV site every 6-8 hrs, and charted on the site Q 1 hour. But apparently, it takes a while for this to occur, seeing as days after the gtt was stopped, the irritation arises?
