Pleurocentesis

     Pleurocentesis is done to remove fluid from the pleural cavity at the lowest safe point in the standing animal. This is done in the recess at caudal mediastinal space. This space is variable among species and in right and left sides.
    As a rule puncture the intercostal space midway between ribs and somewhat dorsal to the junction of the costochondral junction to avoid ventral intercostals vessels.

Horse

In the 7th intercostal space above the superficial thoracic vein on the left side, 6th space on the right side.

Ox

In the 6th, 7th intercostal space above the costochondral junction on both sides.

Dog

In the 7th/8th intercostal space.

Nematodes that parasitize domestic animals are found in all parts of the body but are most commonly found in the digestive and respiratory tracts, and in the circulatory system.
