Extended drip infusion of peripheral parental nutrition containing amino acids might be associated with Bacillus cereus bloodstream infection

Abstract

In some Japanese hospitals, patients using infusion bags for parenteral nutrition containing amino acids have developed Bacillus cereus bloodstream infections. We considered that proliferation of contaminated B cereus in the bag during prolonged drip infusion might be one of the causes of infection. This study indicated that 8 h is the maximum appropriate drip infusion time for peripheral parental nutrition containing amino acids to prevent B cereus bloodstream infections.
