Comparison of rates of extravasation injuries and phlebitis between fixed duration use of peripheral intravenous cannula and standard practice in newborns infants.

This research aims to study the rates of infiltration/extravasation injuries and phlebitis between infants who have an elective removal and re-site of their PIVC at 72 hours compared to those in whom the PIVC is changed due to clinical concerns only. The study follows one episode of PIVC use per baby enrolled into the study. For babies randomised to the elective resite group, the babies will have his/her PIVC electively re-sited every 72 hours. The re-site will be performed by medical staff (neonatal registrar, fellow or consultant). All participants' PIVC site will be monitored by nursing staff for signs of infiltration and phlebitis injuries. The nursing staff are required to document presence or absence of these signs every shift (morning, afternoon or night). If the PIVC sites show clinical indication for replacement prior to 72 hours it will be re-sited.
