1

Whta is EIPH?

strenous exercise associated with extravasation of RBCs from pulmonary vasculature into interstitial space and alveol and airways in DORSOCAUDAL aspect of lung

2

Whta is EIPH?

strenous exercise associated with extravasation of RBCs from pulmonary vasculature into interstitial space and alveol and airways in DORSOCAUDAL aspect of lung

3

Why does EIPH cause poor performance?

bleeding causes lung damage

4

How is EIPH diagnosed?

history and physical exam
endosccopy within 90 minutes of race of workout to detect frank blood in trachea
repeat if not notesd first time endoscopy done
if not then do BAL--blood--phagocytosis by macrophages--hemosiderophage

5

Do most dogs with EIPH have epistaxis

no

6

What are potential causes of EIPH?

1. increased capillary pressure and decreased intrapleural pressure
2. mechanical constraints of abdominal viscera placed on dorsocaudal lung field
3. pulmonary hypertension and stress failure of pulmonary capillaries

7

What may be the effect of EIPH on performance?

1. slow down or stop
2. some labored breathing
3. excessive swallowing
4. coughing?

4. coughing?

9

Why does EIPH cause poor performance?

bleeding causes lung damage

10

What does furosemide do that helps with EIPH?

reduces severity of bleeding
reduces pulonary capillary pressure
increased urine production
decreases blood and plasma volume and body weight
causes hypochloremia and metabolic aklaosis
decreases cardiac output and vascular pressures

3. pulmonary hypertension and stress failure of pulmonary capillaries

13

Evidence of frank blood from nares is present in how many horses with EIPH?

14

What may be the effect of EIPH on performance?

1. slow down or stop
2. some labored breathing
3. excessive swallowing
4. coughing?

15

What is seen on radiograph with EIPH

interstitial pattern esp dorsocaudal lung fields

16

What is the treatment of EIPH?

furosemide

17

What does furosemide do that helps with EIPH?

reduces severity of bleeding
reduces pulonary capillary pressure
increased urine production
decreases blood and plasma volume and body weight
causes hypochloremia and metabolic aklaosis
decreases cardiac output and vascular pressures

18

What are therapyies besides furosemide that help EIPH?

nasal strips
post race intinflammatories help IAD
corticosteroids, bronchodilators--do not lessen EIPH
etc others
