The Lasix rules...
As a physician I will always have trouble accepting this one because in humans the first action of furosamide or Lasix is a response in twenty minutes after pushing the drug. The entire pulmonary capillary circulature dilates allowing for better matching of blood flow and open alveoli units. When the blood volume or pressure is too high, the lungs have areas where there is excessive blood flow but no air gets there or what we respiratory dweebs call V/Q mismatch or shunting.
With a good slug of a loop diuretic such as Lasix the V/Q mismatch is reversed in 30 minutes to an hour.Put a more simplistic way the patient can breathe better.....what could possibly be better for a horse!!!!
Although the increase in capillary area is useful in stopping bleeding in a horses feet and legs the effect in the lungs is profound and thus the horse is more comfortable running.
If the horse hasn't bled they really shouldn't be able to use it......oh well enough clinical stuff time to go play the GG speed bias of the last week. Early Speed is king!!!
I'll post plays later today....
