Hi, I'm also on hospital bedrest. I have an IV port as well. Luckily, they only change mine if I say it hurts or if it looks irritated. I also have had some rough nurse who blew out one of my veins. Then tried with the top of my hand unsuccessfully. It was torture. It was soooo painful! I can't imagine what it's like to do this every 4 days since there are not that many veins in our arms and hands to try! I have asked that they take it out and just put one in if there is an emergency. The doctors said that I must have it in. I don't know what is best because it does make sense to be able to hook up an IV quickly if I need to slow contractions, but I'm not sure that using up my good veins in a non emergency situation is a good idea either.
