Long term ear and saphenous cannulation to perform blood sampling over longer periods using the Seldinger technique (2024)

Bailey, G., Simpson, T., Sharpe, J.

Abstract

The standard practice to collect a blood sample from a Minipig is to invert the animal onto its back and into a cradle. The blood sample is then collected via jugular venepuncture. This technique can cause large amounts of stress for the animal and requires the animal to remain in this position until cessation of blood flow is achieved. By implanting a long-term cannula into a large vessel via the auricular vein or the saphenous vein, the amount of handling, needle sticks and stress to the animal is reduced.
