Change the catheter every 3 days???????????? That's bizarre. Ummmmm.. not where I work. The dressing gets changed by Pain Service when needed but the catheter stays in as long as it works or whatever is planned for. It sometimes takes a while to get it to work just right and with the right med and dose. I don't see them removing it. As Epocrates once said : ' if it ain't broke.. don't fix it.'
Maybe he just needs the practice
