title: A controlled trial of aseptic enteral diet preparation--significant effects on bacterial contamination and nitrogen balance.
abstract: This study was performed to evaluate the clinical effectiveness of the 'standard' and aseptic enteral diet preparation techniques and to investigate the relationship between bacterial contamination of diets and symptoms during enteral nutrition. In this controlled study patients were prescribed isonitrogenous polymeric diets prepared using either 'standard' or aseptic techniques, administered by 24 nasogastric infusion. 'Standard' diet preparation resulted in significant bacterial contamination (p<0.01), but this did not increase incidence of diet related symptoms. Use of sterile techniques permitted safe use of large volumes (1.5-2 litre) containers, and this resulted in significantly better nitrogen intake (p<0.05) and balance (p<0.05).
