š“ Case Study: What Is Wrong With Blaze After the Race?
Meet Blaze, a 5-year-old Thoroughbred racehorse who crosses the finish line and pulls up sluggishly. His jockey notices something alarming: blood streaming from both nostrils.
His trainer assumes a nosebleed. You know better.
Bilateral epistaxis after maximal exertion points directly to exercise-induced pulmonary hemorrhage (EIPH). During Blazeās full gallop, his pulmonary capillary pressure surged to nearly 100 mmHg, physically rupturing the thinnest membrane in his body. Blood flooded his alveoli, migrated through his airways, and exited through both nostrils.
You perform post-exercise endoscopy at 45 minutes and find continuous blood streams covering over one-third of his trachea. That is a Grade 4.
Blaze needs 30 days rest, a full upper airway evaluation, and furosemide before his next race.
š” The takeaway: Bilateral epistaxis after exercise is EIPH until proven otherwise. One nostril tells a different story entirely.
