Presence of tracheal secretions was the main finding in the endoscopy (16/36) followed by pharyngeal lymphoid hyperplasia (14/36), carina edema (13/36),
EIPH (9/36), dorsal displacement of soft palate (3/36), recurrent laryngeal neuropathy (1/36), and epiglottic entrapment (1/36).
For many years decreased athletic performance had been the principal sign related with
EIPH. However, it had been difficult to determine this relationship because there are many confounders involved such as concurrent use of furosemide in horses (Equus caballus), statistical methods, and the number of horses evaluated.
Contacted by the Racing Post, Bladon said: "We haven't used it on any racehorses and it isn't an
EIPH treatment.
EIPH: postrace endoscopic evaluation of standardbreds and thoroughbreds.
Mike Shepherd, a partner at Rossdales veterinary practice in Newmarket, says: "When looked at critically,
EIPH occurs to some degree within all horses under exertion.
More than 80 per cent of racehorses experience
EIPH at some stage during their careers.
The groundbreaking research, conducted jointly by Colorado State University, the University of Melbourne and the University of Pretoria, and involving 167 horses racing in South Africa, showed that giving furosemide before a race dramatically reduced the incidence and severity of
EIPH. Horses were three or four times more likely to have evidence of bleeding without Furosemide and seven to 11 times more likely to have severe bleeding without it.
Vet Tim Beauregard, a partner in the Summerhill Equine Veterinary practice in Naunton, said: "For a bleeder, Exercise-Induced Pulmonary Hemorrhage (
EIPH) is a major issue for some racehorses because it stops them in their tracks when they bleed.
The technical name for bleeding is exercise-induced pulmonary haemorrhage, more generally known as
EIPH.
Exercise Induced Pulmonary Haemorrhage (
EIPH) - more commonly known as bleeding - has been the focus of sustained investigation.
This condition is referred to as exercise-induced pulmonary haemorrhage (
EIPH).
Although exercise-induced pulmonary haemorrhage (
EIPH) has been observed for centuries, the veterinary community has recognised for only the last 30 years that the site of bleeding is a specific area of the lungs.
