Abstract

Recent evidence has shown improved outcomes in pediatric intensive care units with the intensive use of intravenous in-line filtration. This has caused resurgence in interest in filter use but has raised questions in relation to emulsion-based formulations such as propofol. Our objective was to test two propofol products, Diprivan® and Fresofol®, with the Pall Lipipor® TNA and Lipipor NLF intravenous in-line filters and to assay the content before and after filtration under typical infusion conditions. The propofol emulsions were delivered from a 50 mL syringe through an extension set and into either a Lipipor TNA (50 mL/h–1) or Lipipor NLF (20 mL/h–1) filter. Samples were taken at regular intervals and assayed using a high-performance liquid chromatography method before and after filtration. No evidence was found of a significant concentration change during passage of either product through either model of filter. Propofol from two products was found to pass through two different types of Pall 1.2 μm intravenous in-line filters. There was no significant change in concentration before and after filtration under typical conditions of administration. In conclusion, administration of these products through these models of in-line filter would be safe and effective.
