Introduction

  • Essential to investigate health and disease, eg hematology, biochemistries, serology, etc, treat conditions, eg fluid therapy, and perform veterinary procedures such as anesthesia, contrast injection in a CT scan, etc.
  • Good technique and proper restraint are required.
  • Jugular vein → rapid, unobstructed flow of blood but restraint can be stressful and may require sedation.
  • Marginal auricular vein: easy to catheterize, but blood collection a bit more challenging due to easy collapse of the vein. The use of the central auricular artery is controversial, as clot formation can cause ischemic necrosis of the ear tip.
  • Peripheral veins, eg cephalic and saphenous: slow blood flow may produce sampling artefacts (hemolysis and microclots), but easier to locate than jugular and restraint is less stressful.
