title: Evaluation of lyophilized heparin syringes for the collection of arterial blood for acid base analysis.
abstract: The effects of liquid heparin on the analysis of acid/base status of arterial blood include a reduction in PCO2 and an increase in PO2. A study was performed to compare  a lyophilised heparin syringe with a liquid heparin glass syringe for collection of blood for acid/base analysis. No significant difference between the variables measured in blood taken in the two syringes was demonstrated.
