In order to reduce a microbial contamination and needle stick injuries that are associated with a mixing procedure in home parentera nutrition(HPN), nutrition(TPN)solution bags pre-mixed with trace elements may be provided in a form of outer packaging. On the other hand, a packaging form used to enclose the TPN bag after admixture may significantly affect the stability of vitamins. With a focus on possible decrease in vitamin B1 and C content, we investigated the effects of the packaging form. As a result, the TPN bag, which is packed in a light-resistant outer wrap of oxygen-barrier film with an oxygen absorbent under reduced pressure, suppressed a decrease in vitamin content most. However, the decrease in vitamin C content was observed when there was a long time-lag between a preparation and a packaging. We thought it was desirable to pack the TPN bag promptly after the preparation.
