V. CLINICAL EXAMINATION OF THE EQUINE RESPIRATORY SYSTEM Flashcards
T/F: Horses have highly developed hard and soft
palate
T
good indicator during distance observation
head position
most often checked lymph node;
easy to palpate
submandibular
very prominent bone in horses when examining the larynx
atlas
number of ribs covered by the lungs
all; 18 pairs of ribs
Normal sound: Generated in large airways but heard peripherally after
auscultation through aerated parenchyma;
soft, blowing, or rustling sounds
Vesicular
normal sound: Generated in the large airways;
loud, harsh breathing sounds with a midrange pitch
Bronchial
Abnormal sound: Lung sounds louder, because
sounds carried more efficiently
Consolidated areas
Abnormal sound: Lung sounds quieter, but heart
sounds louder
Pleural effusion
Abnormal sound: Both lung and heart sounds will
sound quieter because there’s air surrounding the lungs
Pneumothorax
Abnormal sound: Extra thoracic or large airway
obstruction
Increased inspiratory sound
Abnormal sound: Lower airway obstruction
Increased expiratory sounds
Good indicator of horse’s general health
Jugular vein
Distention or pulsation of the jugular veins may indicate ____ of blood flow to the heart
obstruction
Edema would first show in the ___ part due to gravity
ventral
common complication of edema in the ventral thorax and abdomen
laminitis
usually the first sign observed when the horses are trained intensively
exercise intolerance
Most used imaging in equine practice
Endoscopy
If not genetics, damage to this nerve in cases of Left Laryngeal Hemiplegia
Left Recurrent Laryngeal Nerve
Most common tx for LLH
Laryngoplasty
Laryngoplasty is indicated only for grades __ & ___ of what disease
Grades: 3&4
Dz: LLH
“Hobday” operation
Removal or cut away of laryngeal ventricle and vocal cord
Ventriculocordectomy
Top 2 meds used in equine medicine
Flunixin Meglumine
Phenylbutazone
Identify laryngeal grade: Partial abduction of the affected arytenoid cartilage (b/w full and the resting position)
2: slightly affected abduction, slightly curved
If epiglottis entrapment is recurrent - forms ____ and _____
fibrous tissue and ulceration
Identify laryngeal grade:
Identify laryngeal grade: real failure of abduction; resting position/triangle or bent inwards
3: abduction
Identify the laryngeal grade: Full abduction of the arytenoid cartilages during inspiration
1: no problem
Normal position of epiglottis:
placed dorsally to the trachea
Best tx for Epiglottic entrapment and Dorsal displacement of the soft palate:
Surgical transection
Procedure that is opposite of tie back:
Laryngeal tie-forwards
Conservative Tx for racehorses pre-race in cases of DDSP:
Tongue tie
Pulmonary functions test: Measure how the air goes in and out and around the lungs, bronchi, and trachea after compressing the area:
FOM: forced oscillatory mechanics
Pulmonary functions test: measure amount of air going in and out:
Open Plethysmography
Gold standard for checking upper respiratory issues:
Endoscopy
gold standard for EE, LLH, DDSP:
Endoscopy
