What experts say about getting blood out of stones

Is getting blood out of you a trial for health care staff? If so, help is at hand, according to Associate professor Keith Dorrington and Clinical Pharmacologist Jeffrey Aronson from Oxford University.

They reckon, that perhaps taking blood in the opposite direction, could be the solution for someone for whom the regular tourniquets, hands and feet in hot water, hanging the arm or foot down and gently tapping and stroking veins has failed.

When you have a chronic condition like diabetes, but possibly more so with cancer treatments, someone is always after blood samples. Sometimes a lot. A good sized black pudding’s worth some days. Or at least that is how it seems. When the red stuff fails to flow, all sorts of tricks can be employed but sometimes all you get is tears on both sides. From my own experience I would say that sometimes the best thing to do is to leave it to someone else. Once you have tried two or three times, confidence is lost on both sides and it is best to jack it in.

William Harvey described the circulatory system in the 17th century. The blood flows from the heart to the periphery, that is the hands and feet, and then back up arms and legs via the veins to the lungs and then back into the heart. The Oxford due have discovered that if you put in a small venflon into the smallest vein it will gradually fill up with blood that was intended to go back to the lungs if you put it in facing the fingers.  Worth a try?
