  • Title: Long-term blood-sampling technique in piglets.
    Author: Takahashi H.
    Journal: Lab Anim; 1986 Jul; 20(3):206-9. PubMed ID: 3795856.
    Abstract:
    A technique to enable long-term blood sampling from piglets aged 2-3 months is described. Piglets were housed individually in expandable cages and a heparinized polyurethane catheter was inserted into the external jugular vein. A technique was used which prevented the catheter from pulling out of the vein with growth of the animals. Blood samples could be obtained for more than 1 month, and levels of cortisol, glucose, white blood cell count, haematocrit, rectal temperature and heart rate were compared for samples obtained from simulated conventional venopunctures and from the cannula using this technique. It was shown that restraint and needle pricks raised these levels considerably.
