Abstract
Following a recent study in our Unit which showed that significantly more of prescribed enteral diet was administered from 2-liter bags than 0.51 bottles, a controlled clinical trial was undertaken to investigate further the effectiveness of the 2-liter prepackaged enteral delivery system. Forty patients with normal gastrointestinal function requiring enteral nutrition were randomized to receive nasogastrically 2-liter/day of polymeric diet (2000 kcal, 12 g N) either from a presterilized 2-liter PVC bag (Express EFI Ltd, UK) or from two 1-liter rigid plastic containers filled with cans of Clinifeed 400 (Roussel Laboratories Ltd, UK). The actual volumes of feed infused were monitored in patients fed for 5 days or more. Both nursing and dietetic staff preferred the 2-liter bags which were more convenient to prepare and use. Significantly larger quantities of prescribed diet were delivered from the 2-liter bags than from the 1-liter containers (p less than 0.001). It was concluded that the 2-liter bag system was potentially more convenient and nutritionally efficacious than 1-liter containers. Although the incidence of microbial contamination associated with the 2-liter bags was low, measures to maintain the sterility of this system may need to be more stringent.
