Long-acting aerosolized bronchodilators should be administered twice daily
and 30 minutes prior to exercise in horses with mild to moderate signs of
airway obstruction during exercise.
•
Ipratropium (180 mcg, q 4 to 6 hrs x 14d) Onset of action is approximately
30 minutes, duration of action is 4 to 6 hours.
•
Salmeterol (210 mcg, q 12 hrs x 14d) Onset of action is approximately 30
minutes, duration of action is approximately 12 hours.
Currently, IAD in young horses has thus far given us far more questions than
answers, and much work remains to be done. It is a very diverse condition that can
affect large numbers of young and older athletic horses with varying effects on their
performance.

Introduction
Ultrasonography is invaluable in the diagnosis of a wide variety of problems affecting
the performance horse. Laryngeal ultrasonography has been particularly useful in
identifying poorly performing horses with left laryngeal neuropathy and arytenoid
chondritis. Thoracic ultrasonography is a well-established tool for diagnosing pleural
and pulmonary diseases in horses and monitoring response to treatment.
Sonographic evaluation of the abdomen is useful in diagnosing a wide variety of
abdominal problems affecting the performance horse as well as following their
clinical progress. Peripheral vascular diseases should also be considered in horses
with poor performance.
Certain musculoskeletal problems such as cervical
osteoarthritis and nuchal bursitis and temporomandibular osteoarthritis can also
result in subtle changes in performance without obvious lameness.
Laryngeal ultrasound
The normal sonographic appearance of the equine larynx has been well described.
Ultrasonography of the larynx is useful in the diagnosis of recurrent laryngeal
neuropathy, arytenoid chondritis, dorsal displacement of the soft palate and laryngeal
dysplasia. Laryngeal ultrasonography is a complimentary diagnostic tool for the
evaluation of suspected equine upper airway abnormalities.
