Focal points Over a six‐week period in January and February 2002, 2ml samples were removed from all neonatal PN bags dispensed Samples were submitted for analysis of sodium, potassium and magnesium in triplicate by the hospital's clinical chemistry department using a Vitros Codac 950AT, dry slide, automated analyser Only 19.3, 7.1 and 30.4 per cent of measured sodium, potassium and magnesium concentrations respectively deviated by £5 per cent from stated bag concentrations The results indicate that it is possible that some electrolyte concentrations included in neonatal PN vary significantly from stated values
