Auburn University is equipped to diagnose and treat many different causes of respiratory disease in horses. The equine internal medicine service specializes in evaluation of horses with cough, nasal discharge, bronchopneumonia and pleuropneumonia, blood from the nose, poor performance, strangles infection, or other problems of the respiratory system. Each horse is evaluated with a complete physical/respiratory examination and rebreathing examination (if appropriate), and a diagnostic plan is created for that patient. Diagnostic evaluation may include arterial blood gas, transtracheal wash, bronchoalveolar lavage, pulmonary biopsy, thoracoscopy, upper or lower airway endoscopy, thoracic radiographs, thoracic ultrasonography or thoracocentesis. Once the diagnosis is made, the hospital is equipped to treat and monitor the patients for short and long term care. Climate-controlled stalls are available in the intensive care unit with intranasal oxygen supplementation available, therapy with inhaled medication if necessary, and hourly monitoring.
