How Common Is Eiph In Horses?

An estimated 14% to 75% of racehorses examined by endoscopy have EIPH. On the basis of a bronchoalveolar lavage analysis, a study suggested that 100% of horses performing strenuous exercise have EIPH. EIPH has been reported in various breeds.

How do you prevent EIPH in horses?

Some alternatives to furosemide that are used to prevent and treat EIPH include nasal dilators, con- centrated equine serum, nitric oxide (NO), herbal formulations, conjugated estrogens, aminocaproic acid, a diet rich in omega-3 fatty acids, and rest.

Is EIPH in horses hereditary?

Results from an Australian research project suggest exercise-induced pulmonary hemorrhage (EIPH) may have a genetic component.

Why do horses get EIPH?

EIPH results from strenuous sprint exercise and/or pathologic changes in the equine athlete. It is defined as the presence of blood in the tracheobronchial tree (system of tubes in the lungs) following strenuous exercise. EIPH generally occurs soon after training begins, and tends to increase in incidence with age.

How do you manage EIPH?

The medical treatment for EIPH is to administer a diuretic called Furosemide (brand name Lasix among others) 4 hours before exercise, which increases urine output and thus reduces blood volume. In this way it has been shown to reduce calculated pulmonary capillary blood pressure and transmural pressure.

Is EIPH common?

(Epistaxis, “Bleeder”)
Exercise-induced pulmonary hemorrhage (EIPH) is seen in most racehorses and in many other horses used in equine sports (eg, polo, barrel racing, 3-day events) that require strenuous exercise for short periods of time. Epistaxis is seen in a small proportion (~5%) of horses with EIPH.

Can humans get EIPH?

EIPH in humans may occur without any evidence on clinical presentation; its incidence may be far greater than currently suspected.

What percentage of horses with EIPH show signs of epistaxis?

Epistaxis is seen in a small proportion (~5%) of horses with EIPH. Blood in the tracheobronchial tree is identified in 45%–75% of racehorses via endoscopic examination, and hemorrhage is detected by cytologic examination of bronchoalveolar lavage in >90% of racehorses.

How is EIPH diagnosed?

EIPH in horses occurs when fragile pulmonary blood vessels in the lungs rupture during exercise. Lung bleeding can be detected by endoscopic examination. During the scoping, a long thin tube with a camera on the end is passed through the horse to view the upper airway and trachea.

Why are horses predisposed to atrial fibrillation?

Horses are predisposed to atrial fibrillation because of their large heart size. Furthermore, horses that have a dilated heart because of underlying heart disease (valvular regurgitation) are more likely to suffer atrial fibrillation.

What do I feed my EIPH horse?

Both of these studies illustrate the possibility that a diet high in omega-3 fatty acids may reduce the incidence of EIPH. Fish oils (cold-water species) and flaxseed (linseed) oil are rich in omega-3 fatty acids.

How can I increase blood flow to my horses feet?

Regular exercise gets the muscles contracting and the heart pumping, thereby increasing blood flow to all your horse’s tissues and organs. On the correct footing, exercise helps to increase blood circulation to your horse’s hooves as well, encouraging proper formation and growth.

Do horses run faster on Lasix?

Lasix also works as a diuretic that causes horses to urinate before a race and lose 20 to 30 pounds of fluid, thus increasing the ability of the horse to run faster.

Is EIPH a disease?

In horses, the 2015 American College of Veterinary Internal Medicine Consensus Statement made the strong recommendation that EIPH be considered as a disease rather than a “condition”.

What is the best treatment for an arterial bleed?

To treat arterial bleeding, apply direct pressure. If the patient is able, ask them to hold a thick pad or dressing in place while you secure it with roller gauze. Do not lift the dressing to see if the bleeding has stopped.

How do you stop vascular bleeding?

Pressure Points for Severe Bleeding
When you apply pressure to an artery, you stop bleeding by pushing the artery against bone. Press down firmly on the artery between the bleeding site and the heart. If there is severe bleeding, also apply firm pressure directly to the bleeding site.

Why is my horse coughing up blood?

Severe hemorrhage from the respiratory tract in horses is mainly associated with mycosis of the guttural pouch, exercise-induced pulmonary hemorrhage (EIPH), invasive procedures causing serious trauma to nasal conchae, or lung biopsy [1, 2].

Why do horses bleed internally?

When galloping, racehorses have a very high cardiac output that pushes blood through the pulmonary circulation. This creates very high pressure in the pulmonary capillaries whereby they may rupture releasing blood into the alveoli of the lung.

What does it mean for a horse to be a bleeder?

For over 300 years, horse riders have seen blood at the nostrils during or soon after performance work in a percentage of athletically trained horses. The condition has been named Exercise Induced Pulmonary Hemorrhage or EIPH and affected horses are commonly known as “bleeders”.

Is EIPH fatal?

EIPH is seldom fatal; postmortem lesions in the lungs of horses that have been affected with several episodes of hemorrhage are characterized by large areas of dark brown discoloration, largely in the caudal lung lobes.

What happens when a horse burst a blood vessel?

These vessels burst, causing blood to flow out of the lung. It is not painful for the horse, but free blood in the lungs can oxidize and lead to secondary inflammation. In the longer term, repeated bleeding can harm the horse’s respiratory capacity, resulting in a progressive decline in performance.
