I have been asked to research policies and procedures concerning the use of Sono-guided peripheral IV placement. We are usually asked to assist in difficult IV placement for imaging studies. In the past, this has not gone well. I have seen at various sites and references that the length of the cannula used as well as the removal of the cannula after the study are points to be considered. These are in patients who are not really candidates for centrakl lines or PICC lines since they are typically not recieving long term IV therapy, i.e., discharged after the study is completed.
