This is a new concept to me, as a nurse. I had heard about this about 6 months ago for the 1st time. Someone at work was talking about it. It is hard to believe that it has been around much longer than this, and I am just now getting familiar with it. I found a couple of videos on YouTube that explains how to start a Subcutaneous Infusion Therapy. This is a pretty cool thing that is available, especially for elderly patients.
