We call it a "Normasaline Bag" in front of patients sometimes. We never expressly say that it's medicine, so we aren't open to liability, but it makes some of the more hypocondriac among our patients to calm down, because saying "Normal Saline" that fast makes them think there is something good coming.
You wouldn't believe how many of them just fall asleep after we start the flow, thinking they are getting something a little more powerful than fluids
