RE: [RC] EIPH bleeder??? - Susan E. Garlinghouse, DVM
I would definitely get him scoped to see if you can find the
source of the bleeding. If it’s coming from the lower respiratory
tract, then there are limited treatments open to you---on the race track, they
use Lasix to thin the blood, but that’s not allowed in AERC and the Lasix
isn’t particularly effective, anyway. They still don’t know
exactly what causes EIPH, but feel it’s probably related to the 300-400% increase
in blood pressures between the right ventricle and pulmonary loop as blood
circulates through the very small and thin-walled capillaries of the lungs.
It is also possible that the blood may be originating from the
guttural pouches, and possibly related to a fungal problem (guttural pouch
mycosis). The guttural pouches in horses are somewhat unique in that the
internal carotid artery runs past it at a very shallow depth as a heat loss
mechanism during exercise. A fungal infection can erode the artery wall
and can potentially cause a fatal blowout. Don’t lose sleep over it
yet, though---if there were a fungus up in there, you would generally also be
seeing other symptoms and it’s doubtful he would have otherwise performed
well at an endurance ride.
There are lots of other minor issues that could cause some
sporadic bleeding, but you won’t know until someone takes a good look up
there.

I
am looking for some information on EIPH. My gelding at times has a very thin
spray of blood in his nostrils very a day of hard riding. We thought it was
because he does like rhymic breathing when he is working hard.. likes to hear
himself breath. But at the edurnance ride yesterday he had more blood than
nomal in his nostrils.. not dripping or pooling but you could see he had blood
in his nostrils. This was after completing a LD on a 70 degree day. The vet
said I needed to get him scoped. Which I propably will. Also suggested chinese
herbs.
What
do other people do for this problem.. at no time was he having any problems if
anything he was being held back.. he loves to go and is in condition for the
sport. he turns 8 in May but has just started his endurance rides.. only 4 thus
far.
