Equine resp Flashcards
The rebreathing exam in horses is
Stiff plastic bag
Rebreathing exam
10:50
https://www.youtube.com/watch?v=1xzUhC65OtQ&t=15s
Take a plastic bag or rectal sleeve to seal off lips and mouth so they have to rebreath there own CO2
The vet should be listening to the lungs at the same time
As the CO2 rises they will resist
Take the bag off and they will take a couple deep breaths
May have to do it a couple times
Also called bagging a horse
Asphyxiation in horses
Secondary to facial swelling, mass in larynx
Stridor
Strong inspiratory effort
Distress
Blue/muddy mucous membranes
Hypoxia
How to preform a Tracheotomy on horses
Junction of cranial and middle ⅓ trachea
Midline incision
Incise ⅓ diameter between tracheal rings
Insert tracheotomy tube or alternative
Recurrent laryngeal neuropathy in horses is and diagnostics
AKA Left Laryngeal Hemiplegia, “Roarer”
Denervation of the recurrent nerve on the left side
Unable to abduct left hemi-larynx
Diagnostics
Upper airway endoscopy
Sx- prosthetic laryngoplasty(“tie back”)
Guttural puouch mycosis is
Fungal growth on internal carotid artery of guttural pouch
History of intermittent epistaxis or single massive epistatic episode
Emergency!
Endoscopy to confirm
Surgery
Strangles in horses is and who is suceptable
Streptococcus equi equi
Highly infectious
Abscessation of the mandibular and retropharyngeal lymph nodes
Typically young
Vaccine available
Can get into any lymph nodes internally “bastards strangles”
Asthma in horses are caused by and treatment
Constriction of bronchioles secondary to allergen
Mold spores in round bales
Increased resp effort with expiratory push, frequent coughing
Have trouble getting air out, not in
“Heave line” and nostril flare
Bronchioalveolar lavage for diagnosis
Steroids and bronchodilators as management, avoid allergens
Treatment
Transtracheal wash
Bronchoalveolar lavage
Exercise Induced Pulmonary Hemorrhage in horses is and caused by
Horses with this can be called bleeders
Mild epistaxis following exertion
Secondary to transient high blood pressure during intense exercise
Upper airway endoscopy, BAL
Pleuropneumonia in horses is caused by and treatment
Also called shipping fever
Mixed bacterial infection
Usually following trailer ride with head tied and hay net
High fever, reluctance to walk, like cough, lethargy
Hospitalization, chest drain
Cachexia
Prognosis guarded
Influenza and Equine Herpes Virus-4 are and cause
Two separate viral infections that present very similarly
Primarily young horses recently in contact with new horses
Fever, tachypnea, frequent coughing
Increased risk of developing bacterial pleuropneumonia
EHV-1 can cause resp disease OR abortion OR neurologic signs
High fever + cough = nasal swab to rule out EHV-4
A complication of strangles in horses is
Purpura hemoragica can happen
Reaction to the protein on the bacteria
Happens to horses that have had stangels before
Go into an extreme immune reaction
Shock type treatment needed
Never admit a horse into main hospital suspected of having strangles
