  • Title: A protocol for the routine measurement of lactate and pyruvate in cord blood.
    Author: Prentice A, Vadgama P, Appleton DR, Dunlop W.
    Journal: Br J Obstet Gynaecol; 1989 Jul; 96(7):861-6. PubMed ID: 2765431.
    Abstract:
    The influence of the site of sampling and the delay in sample collection on cord blood concentrations of lactate and pyruvate were investigated. A delay in sample collection of greater than 1 min after cord clamping could invalidate the results obtained. Samples from umbilical artery had higher lactate values (mean 3.13 mmol/l) than paired vein samples (mean 2.32 mmol/l) but there were no significant differences in lactate values between different sites sampled within the umbilical vein. A calculation was devised to circumvent the need to take cord blood samples immediately after delivery.
