Any factors that increase negative pressure in the upper
respiratory tract (URT), can influence its mechanics. The aim
of this report was to describe the results of URT diagnostic
evaluation with overground endoscopy (OE) in sport and
pleasure horses.
The URT and plasma lactate levels were evaluated during rest
and during overground endoscopic examination in 19 cases.
Horses performed their normal training session. When history
and clinical examination suggested a lower airway
obstruction, we performed bronchoalveolar lavage.
Dorsal displacement of the soft palate (DDSP) was diagnosed
in 8/19 horses, which might have developed secondary to URT
or lower respiratory tract inflammation or obstruction. DDSP
was also detected at rest in 4 cases. Laryngeal hemiplegia
(LHP) was diagnosed in 15/19 horses, 11 of which were complex
cases with other types of URT obstructions. Severe pharyngeal
collapse, suspected already at rest, was visible in two cases
during exercise. In contrast, pharyngeal collapse diagnosed
with nasal occlusion at rest in two cases was fully
compensated under the rider. Plasma lactate levels
significantly decreased during exercise.
All DDSP cases were suspected to be of inflammatory or
obstructive origin, which is different from findings in
racehorses, where extrinsic causes are more common. Resting
endoscopic examinations were sensitive in cases of
obstructive origin. LHP and pharyngeal collapse could not be
predicted on the basis of findings at rest, and increased
neuromuscular activity during exercise could compensate for
the problem in less severe cases. Decreased levels of
lactate could be explained by the increased clearance during
exercise.
