Transtracheal/Bronchial wash

39
Q

3 techniques to a transtracheal/bronchial wash

A
  1. Percutaneous
  2. orotracheal
  3. bronchoalveolar
40
Q

Area is injected with lidocaine, jugular catheter is placed in the trachea and flushed with saline, when the animal coughs retract plunger and collect sample

A

Percutaneous

41
Q

Requires light anesthesia and placement of an endotracheal tube
Urinary/jugular catheter is placed through endotracheal tube and flushed with saline. Animal may not cough, so the sample should be collected after a few seconds

Bronchoalveolar

43
Q

Remember to collect ___ fluid expelled when an animal coughs and put into a red top tube
