Feline asthma and chronic bronchitis Flashcards
Coughing in younger cats and kittens- increases suspicion of…..
infectious disease cause
respiratory issues in older cats- increases suspicion of ……
other diseases such as:
hyperthyroidism
neoplasia
cardiac disease
signalment of lower airway disease
tends to affect young adult to middle aged cats
what is feline lower airway disease
used to include feline asthma (a condition of reversible bronchoconstriction in response to inhaled allergens), and chronic bronchitis (a condition of airway thickening and excessive mucous).
Describe the breathing pattern that you tend to see in cats with laryngeal disease
laboured inspiration - stridor, increased effort and slow inspiratory phase
may have change in purr or vocalisation
Describe the respiratory pattern that you tend to see in cats with lower airway disease
laboured expiration- prolonged expiratory phase, additional expiratory push, audible expiratory wheeze
increased airway resistance
occasional cough
What is chronic bronchitis
inflammation of the bronchi persisting over a long time
Response to an infection or inhaled irritant
How does airway obstruction occur in feline asthma
bronchoconstriction
inflammation
mucous plugs in narrowed bronchioles
List 5 differential diagnosis for coughing cats
URT disease
inflammatory lower airway disease
infectious
foreign body
neoplasia
What is PPDH
Peritoneopericardial diaphragmatic hernia
why do we need to careful when doing bronchoscopy/ BALs in cats
they have very sensitive airways and this can cause bronchoconstriction
List 5 things that you may see on a radiograph of a feline inflammatory airway disease patient
bronchial patterns
hyperinflation
air trapping
collapse of R middle lung lobe
air in stomach
List differentials for eosinophilic inflammation of the lungs
feline inflammatory airway disease
viral pneumonia
parasites
hypereosinophilic syndrome
What may you see on BAL of a cat with congestive heart failure
iron in the macrophages - known as heart failure cells
Describe a management plan for feline inflammatory airway disease
corticosteroids- dexamethaone IV
beta-2 agonists- to manage bronchospasm (terbutaline or inhaled salbutamol)
oxygen therapy
reduce allergens- if you know them
prednisolone po for 2-3 weeks
