Reducing waste in parenteral nutrition: comparison of Surgical- and Standard-Aseptic Non-Touch Technique.

The NHS accounts for approximately 4% of carbon emissions in England. Aseptic techniques are an area where the use of consumables, and subsequent waste, may be high. Traditionally, administration of parenteral nutrition (PN) has been performed using a so-called sterile technique. The aim of this study was to compare the volume of waste generated from a traditional 'sterile' technique (Surgical-Aseptic Non-Touch Technique (ANTT)), using sterile gloves and a dressing pack, and Standard-ANTT, using non-sterile gloves, a general aseptic field and a micro-critical aseptic field where necessary in the administration of PN. Two procedure trays were arranged representing consumable equipment used in each procedure. All items including packaging were weighed. Standard-ANTT demonstrated an estimated 52% reduction in waste and carbon emissions. There is a pressing need for nurses to review practice and consider where more sustainable choices can be made in the administration of PN. [ABSTRACT FROM AUTHOR]
