ABSTRACT
Iatrogenic manganese (Mn) neurotoxicity is a safety concern in neonates receiving parenteral nutrition (PN). Prior studies suggest Mn contamination of PN ingredients represents an unintended source of Mn delivery. In order to determine the relative contribution of unsourced Mn to total Mn exposure in neonatal PN, this study measured Mn concentrations in neonatal PN solutions using inductively coupled plasma mass spectrometry. Solutions prepared using a standard fixed dose neonatal multiple trace element product were compared with test solutions prepared using individual trace element ingredients not including Mn. The standard solutions (nâ=â6) contained a mean (SD) Mn concentration of 56.63âµg/L (0.94), compared with 6.04âµg/L (0.39) in the test solutions without added Mn (nâ=â6). This study suggests that neonatal PN contains significant quantities of Mn not intentionally added during PN preparation. Further studies are needed to identify individual ingredient sources of unintentional Mn, and the feasibility of Mn omission strategies.
