Clinical Resp Med (SA) Flashcards
Which dogs are most predisposed to chronic bronchitis?
toy breeds
Which Dz is characterised by an increase in rest mucus, lost/damaged cilia and a chronic cough which is worse with excitement?
Chronic Bronchitis
which parasite causes nodules at the tracheal bifurcation and expiratory bronchial collapse?
Oslerus Osleri
Which parasite is visualised as worms on tracheobronchoscopy?
Crenosoma Vulpis
which 2 cells types are visible on normal canine/feline BALf?
ciliated columnar cells
Goblet Cells
which 3 things are increased on BALF cytology in chronic bronchitis?
mucus
neutrophils
macrophages
which 2 bronchodilators are useful for chronic bronchitis management?
theophylline
terbutaline
what non-medical interventions can be taken to manage chronic bronchitis?
weight loss
harness instead of collar
avoid irritants
keep mucosa moist - nebulise/steam
Which drugs should be used alongside bronchodilators in chronic bronchitis?
glucocorticoids
can also use mucolytics if much-ciliary clearance compromised
which antibiotics are involved in the 4-quadrant therapy for life-threatening pneumonia?
potentiated amoxicillin
fluoroquinolone
metronidazole
Young, large breed dogs are often susceptible to which spectrum of disease, caused by a hypersensitivity to inhaled allergens?
Eosinophilic bronchopneumonia
What is the cytological criteria for EBP?
> 25% eosinophils
What is the mainstay Tx for EBP?
prednisolone

Fluticasone
Which drug is given orally q12h to control feline asthma?
Terbutaline (B2 agonist)
Which imaging modality is best for checking out a pleural effusion?
