Intratracheal administration

In clinical practice for lung diseases, medicinal substances are administered intratracheally using a probe. Before administration, the probe is disinfected and lubricated with petroleum jelly. For large animals, the probe is inserted through the nasal cavity to the pharynx and in between the swallowing movements it is further advanced. With the correct insertion of the probe into the trachea, the animal develops a cough that soon disappears. To make sure that the probe in the trachea, grasp its initial part with the left hand and make jerky movements back and forth, while the impact of the probe against the tracheal wall is clearly audible. In addition, when the probe is inserted correctly, a stream of exhaled air is felt.

Intratracheal drug solutions can be administered using a needle.
To do this, at the injection site, the hair is cut, disinfected with tincture of iodine, alcohol. A sterile needle is inserted between the rings into the trachea. Then, in the syringe or funnel, the desired amount of the drug solution of the animal’s body temperature is poured. After making sure that the solution is well flowing, the cannula with a rubber tube worn on a funnel or Janet syringe is connected to the needle. A funnel or syringe is raised to the occipital part of the head. If the animal is in a supine position, it is possible to introduce medicinal substances into the right and left lungs. After the introduction of the solution, the needle is removed, and the injection site is disinfected.
