Randomised controlled trial of routine replacement of peripheral cannulae versus removal on clinical indication

None listed

In Australia each year ten million intravenous (IV) drips are inserted in patients’ arms or in the backs of their hands to give fluid and medications. Many drips are routinely replaced every few days in the hope that this reduces infection, however preliminary research suggests it would be better and more cost effective to leave them alone. That would save patients the pain of another needle as well as interruption to treatment. It would save doctors and nurses time, and reduce waste from plastic disposables. The research will provide the evidence to know one way or the other whether IV drips should be routinely changed or left alone.
