title: Minimal haemolysis in blood co-infused with amino acid and dextrose solutions in vitro.
abstract: OBJECTIVE
  To examine the haemolytic effects of amino acid and dextrose solutions on co-infused packed red blood cells.
  
  
  METHODS
  An in vitro study of packed cells co-infused at various rates with dextrose 5%, 10%, 15% and intravenous amino acid solution (Vamin; Kabi-Pharmacia, Baxter Healthcare Pty Ltd) in dextrose 5%, 10% and 15%. The degree of haemolysis was measured as free oxyhaemoglobin by spectrophotometer. Co-infused 0.9% saline and water were used as 0% and 100% haemolysis controls.
  
  
  RESULTS
  Only minimal haemolysis was observed with the solutions tested. The greatest observed amount of haemolysis was 0.14%.
  
  
  CONCLUSIONS
  Co-infusion of packed red blood cells with dextrose and amino acid solutions at the concentrations and infusion rates commonly used in neonatal care, does not cause clinically important haemolysis.
