Unfortunately, the simple and universal design of the Luer connector allows for connection between unrelated delivery systems—that have different intended uses (e.g., vascular, enteral, respiratory, epidural, and intrathecal). As a result, care providers can inadvertently connect wrong systems together, causing fluids (e.g., medications, enteral feedings) or gases (e.g., oxygen) to be delivered through the wrong route. The consequences can be fatal to patients. (REF FDA MEDSUN webcast Nov 2008)
