increased resp effort, exercise intolerance, cough
what are the solutions for lower airway diseases surgically?
cut what ever is causing disease out and remove it
what are the C/s for pleural space disease
depends on vol and rapidity of fill
restrictive breathing pattern (rapid and shallow to maintain minute vol)
rapid onset
how can you treat pleural space disease surgically?
drain the air/fluid and treat inciting cause
what does BOAS stand for?
brachycephalic obstructive airway syndrome
what are the factors involved in BOAS?
- stenotic nares
- aberrent turbinates
- elongated, thickened soft palate
- oversized tongue
- everted laryngeal saccules
- hypoplastic trachea
- laryngeal collapse, tracheal collapse
what are the C/S of BOAS?
- resp noise
- stenotic nares
- GI signs (difficulty swallowing, regurg, gastroesophageal reflux)
- obstructive sleep apnea
- heat intolerance
- cyanosis and collapse
how do you diagnose BOAS?
- PE
- laryngoscopy/endoscopy
- CT, rads
how do you manage BOAS?
- weight mgmt
- avoid overheating
- open nares (rhinoplasty)
- open turbinates (endoscope guided turbinectomy)
- shorten soft palate (staphylelctomy) or also thin it (folded flap palatoplasty)
- partial tonsillectomy
- laryngeal sacculectomy
- ongoing observation…
we do not cure BOAS!!!!!
what are the risks of BOAS treatment?
post-op airway inflammation/swelling
aspy pneu pneu
what is a hiatal hernia?
when stomach herniates through diaphragm (alongside esophagus in esophagus hiatus) into the thoracic cavity
what is the general pathophys of laryngeal paralysis? who gets it?
typically older large breed dogs, idiopathic acquired
vagus –> recurrent laryngeal nerve –> caudal laryngeal nerve
cricoarytenoideus dorsalis (CAD) fails to abduct the arytenoid cartilage
problem when bilateral
what are the C/S of lar par? (laryngeal paralysis)
- change phonation, gagging/coughing esp when E/D
- exercise intolerance
- heat intolerance
- laryngeal stridor
- acute dyspnea
- cyanosis, syncope
- regurg (megaesophagus)
progressive disorder
how do you diagnose lar par (laryngeal paralysis?)
rads
laryngoscopy under light plane anesthesia
how do you manage laryngeal paralysis? lar pars
- cooling, O2 therapy, anxiolytics
- emergency tracheostomy
- mild: weight loss, stress reduction, exercise restriction, avoid heat (progression)
- mod/severe: unilateral cricoarytenoid lateralization (unilateral “tie-back”)
we do not sure lar par :(
what are the risks for lar par intervention?
- GOLPP (geriatric onset laryngeal paralysis polyneuropathy)
- aspy pneu pneu = life long risk
tracheostomy can be used for any obstruction… where?
forward of larynx
BOAS, laryngeal collapse, lar par, granulomas
what can you do to surgically treat tracheal collapse? what should you do first?
first, try medical management!!!
stending (intraluminal > extraluminal)
dogs with severe, refractory tracheal collapse benefit from earlier stenting
malformation type collapse is more likely to require tracheal stenting
what is spontaneous pneumothorax?
leakage of air from lung without evidence of trauma
what are the C/S of pneumothorax?
mild: asymptomatic
mod/severe: restrictive breathing pattern, hypoventilation, diminished lung sounds
can be fatal
how do you diagnose pneumothorax
- PE
- rads (once stable)
- CT (?)
how do you tx pneumothorax?
- thoracocentesis
- thoracostomy tubes for animals requiring ongoing drainage
- continuous suction
- autologous blood patch? [last ditch effort, fibrin from this “helps”]
- surgery
pyothorax:
1. typical signalment?
2. what type of bac t?
- young. hunting/working breed dogs over represented
- obligate anaerobes or mix of obligate and facultative anaerobes; bac t tend to reflect oral cavity and URT
what are the C/S of pyothorax?
tachypnea, dyspnea, cough, lethargy, weight loss, anorexia, restrictive breathing pattern, muffled breath & heart sounds
may be afebrile
SIRS, sepsis… often
often fatal
how do you diagnose pyothorax?
- thoracocentesis –> cytology
- imaging
how do you medically treat pyothorax?
