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.
