Abstract

A simple catheterization from the ear vein into the jugular vein or anterior vena cava was tried for sequential blood sampling from unrestrained pigs for clinical research on stress. Insertion of the catheter was made from the middle or lateral auricular vein by using a trocar-cannula type needle in standing position with restraint of the snout. Vinyl tubes of various sizes were used as the catheter. The free end of the catheter was plugged and fastened at several site of the auricle, neck and back. Sequential blood samplings were made with an injector adapted to an extension tube. Smooth blood sampling was possible without any restraint in standing position for 3 days in pigs weighing 90 kg.
