Effect of Delaying Replacement of Parenteral Nutrition Intravenous Administration Sets: Preclinical Experiments and a Dynamic Laboratory Model of Microbial Colonization

Abstract

All-in-one PN and IVFE support the C. albicans growth after minimal initial contamination, with micro-organisms migrating from the fluid bag to the central venous access device. Improved aseptic nontouch technique during clinical practice is vital to prevent contamination. Daily IVAS replacement of for all-in-one PN and IVFE should continue until the safety of prolonging IVAS replacement is confirmed by randomized trials.
