ReviewBacterial contamination of multiple-dose vials: a prevalence study.
Two patients died of a meningitis caused by Pseudomonas aeruginosa in a hospital in Germany in July 2001, their infections having been caused by a contaminated contrast media (iomeprol [Imeron]) used as a multiple-dose vial (MDV) over 8 days. Therefore, a prevalence study was performed to investigate the use and contamination of multiple-use vials in a tertiary hospital. ⋯ Results revealed somewhat risky handling of MDVs. In light of a possible high risk in this hospital of about 1 contaminated MDV per day, and in view of many reported outbreaks induced by contaminated MDVs, the following infection control measures were encouraged: alcohol hand hygiene, the disinfection of gums, observance of the manufacturer's recommendations, appropriate storing temperatures, marking the opening time, and avoiding the multiple use of medications not containing preserving agents.
