Determining the best time to diagnose EIPH in horses  

Determination of the Correct Time and Diagnostic Tool to Diagnose EIPH in Barrel Racing Horses


Purpose of Study

This study is being done to help us determine the best time to perform endoscopy and bronchoalveolar lavage (BAL): two procedures used to diagnose Exercise Induced Pulmonary Hemorhhage (EIPH) and Lower Airway Inflammation in barrel racing horses.  


You and your horse will be aiding future barrel racing horses by helping us determine the best time for diagnosing EIPH and Lower Airway Inflammation.  In addition, all study procedures will be done at no cost to you. Once we have analyzed the data and samples your horse provides, we will email the results to you. 

Enrollment Requirements

To qualify for this study, horses must be known or suspected “bleeders” and must participate in a barrel race immediately before the study procedures.

Treatment Methods

Enrolled horses will receive a full examination approximately 30 minutes after their race.  Once examined, they will be lightly sedated and at 60 minutes, post-race, a fiberoptic endoscope will be passed via the nostril down into the trachea where we will look for evidence of hemorrhage and record real-time images. This endoscopy will be repeated up to 4 more times at 120, 180, 240, and 300 minutes, post-race.  At the final time point (300 minutes), we will also pass a tube all the way down into the lungs and perform a bronchoalveolar lavage (BAL): a procedure where a sterile solution is flushed through the airways.  We will collect this fluid and analyze it for the presence of blood and white blood cells. Both the endoscope and BAL procedures are very low risk and should take 10-15 minutes to perform.  

Owner Responsibilities

Owners are responsible for contacting Dr. Gold if they would like to enroll their horse(s) in the study. They will be required to sign a client consent and will need to allow their horse to remain at the race location for the duration of the procedures (300 minutes after the horse’s race).

Study Locations

Dr. Gold will be traveling to various races around the Pacific Northwest from March 2019 through September 2019 to do this study.  If you would like a list of the races she will be attending or to request she attend a race, please contact her using the information below.
