Re: RC: Re: [Enduranceriders] Metabolic Pulls at Tevis

Here's something to know about IVs. Every time you puncture the jugular vein 
you do damage. Not only do you damage the vessel itself, but Rantannen, et al 
have shown that IVs tend to cause aggregation of blood cells. These agregates 
then flow into the heart and attach themslves to the wall of the heat (and 
probably to blood vessels as well, but Rantannen was just looking at the 
heart). Later, they pull away, leaving a lesion behind, and then move on into 
the lungs, where they plug up small capillaries--not good in a racehorse, 
because these capillaries later explode and the horse bleeds from the lungs 
in a race. 

Others have found that venous injections cause small particles of debris 
(hair, skin, maybe dirt) to flow into the lungs, where they are encapsulated 
and sometimes become infected--more damage.

In racing, it is my position that, when the needle goes in, the owner/trainer 
has made a big mistake.
