Exercise Induced Pulmonary Hemorrhage (EIPH) Flashcards
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
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
Why does EIPH cause poor performance?
bleeding causes lung damage
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
Do most dogs with EIPH have epistaxis
no
What are potential causes of EIPH?
- increased capillary pressure and decreased intrapleural pressure
- mechanical constraints of abdominal viscera placed on dorsocaudal lung field
- pulmonary hypertension and stress failure of pulmonary capillaries
What may be the effect of EIPH on performance?
- slow down or stop
- some labored breathing
- excessive swallowing
- coughing?
What may be the effect of EIPH on performance?
- slow down or stop
- some labored breathing
- excessive swallowing
- coughing?
Why does EIPH cause poor performance?
bleeding causes lung damage
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
Do most dogs with EIPH have epistaxis
no
What are potential causes of EIPH?
- increased capillary pressure and decreased intrapleural pressure
- mechanical constraints of abdominal viscera placed on dorsocaudal lung field
- pulmonary hypertension and stress failure of pulmonary capillaries
Evidence of frank blood from nares is present in how many horses with EIPH?
What may be the effect of EIPH on performance?
- slow down or stop
- some labored breathing
- excessive swallowing
- coughing?
What is seen on radiograph with EIPH
interstitial pattern esp dorsocaudal lung fields
