Lecture 13 - coughing cases (specht) Flashcards
what diseases would you consider cough suppression?
non productive ones collapsing trachea chronic allergic bronchitis neoplasia HW dz
which would not cause cyanosis? anemia CHF forgetting to turn O2 on during anesthesia pneumonia PTE
Anemia; RBC can still carry O2 there’s just not enough RBCs
the others all involve RBC not getting enough O2
heart dz that can cause coughing
CHF from; DCM, HW, pulm hypertension, endocarditis, endocardiosis
T/F: patients with CHF causing cough will probably have a murmur and fast HR
true
T/F: patients with atrial enlargement causing cough will probably have a murmur
true
T/F: a fast HR + loud heart murmur + crackles confirms CHF in coughing patient
False
respiratory causes of cough
non-cardio edema pneumonia hemorrhage PTE neoplasia
6 yo FS DSH NP cough, tachypnea/dyspnea, increased expiratory
asthma
0.6 yo MN Golden acute NP cough
CIRD
6 yo MN Poodle acute P cough, tachypnea/dyspnea
bacterial pneumonia
dyspnea is not usually a CS of chronic bronchitis and this cough is acute and productive
10yo M basset chronic, dry, NP cough, increased expiratory
chronic bronchitis
6 yo F pomeranian chronic, progressive, NP loud cough, increased inspiratory
collapsing trachea
if a dog had mild tracheal collapse that suddenly worsened think
concurrent dz, something is making p breath harder (weight gain? )
medical management for collapsing trachea
weight loss
cough suppressants
harness
cough suppressants used in collasping trachea cases
hydrocodone
lomotil
cons: sedation and constipation
ideal order of dx for a coughing patient
MDB HW, FeLV/FIV CXR fecal CT
risks of tracheal stent sx
improper measurement of stent
granuloma formation
migration of stent
stent failure
most dogs with tracheal collapse have been show to have concurrent tracheal __
malformations
may require additional sx like ballooning with the stent
sign of chronic airway dz that can be seen on radigraphs and puts patient at higher risk of infection/persistent infections
bronchiectasis (really big bronchi)
PI may require lung lobectomy
if there is still __ after tracheal stent placement the patietn will still cough
bronchial collapse (may need bronchodilator)
always one of the top dx tests for a coughing patient
CXR , doesn’t give a dx but helps localize ddx
interstitial to bronchial pattern in coughing cat
asthma
HW
neoplasia (lymphoma)
multifocal, interstitial well defined nodules dog CXR
Neoplasia
fungal granuloma
what causes crackles
fluid in, collapse or opening of the small airways/alveoli
parenchymal fibrosis
what does an end-expiratory grunt indicate
air-trapping and/or obstruction of lower airways
must put effort and use diaphragm to get the air out of lungs
airway washes can be helpful to differentiate
bronchitis/asthma
neoplasia
pneumonia
patient is coughing but not tachycardic, what can be r/o
heart dz
on CXR the cardiac silhouette and diaphragm have a lot of space between them; this indicates
hyperinflated lungs
pleural space dz causes increased __ time
inspiration
SE of BAL is transient __
hypoxia
__ may be seen on BAL cytology and indicate chronic bronchitis
curshmann’s spirals (mucus)
__ is a contaminant from the mouth that is large and purple and may be seen on BAL cytology
simonciella ; do not treat this!
general tx for canine chronic bronchitis
steroids
cough suppression
weight loss
environmental control
+/- bronchodilators
what would make you include antibiotics as part of therpy for aspiration pneumoninits
develop fever after 1-2d
on PPI at time of aspiration
worsening inflammatory leukogram after 2-3d
