Wow...this actually exists?  That would be great if it does.  No more risk of infection.  No more bleeding to death, and this would impact on so many other medical miracles.

In a series of experiments in 1665, Richard Lower attempted to transfusion blood from one dog to another. Baring the vein of one test animal and the artery of another, he would stitch them to opposite ends of a reed so blood could flow from one animal into another.\n\n? A record of this experiment is contained in the diary of Samuel Pepys.\n\nJean Baptiste Denis, was a physician to Louis XIV At precisely 6 in the evening on December 19th, an associate opened a vein in Mauroys's arm, inserted a silver tube and drained off about 10 ounces of blood. He then inserted the other end of the tube into the leg artery of the calf and allowed about a cupful of the calf's blood to flow into the man. The doctor hoped he calf's blood "by its mildness and freshness might possibly allay the heat and ebullition of the patients blood".\n\nLaboring over the patient, Denis watched for signs that the transfusion had taken effect. Minutes passed as the calf's blood flowed through the tube.  Tow hours later, the patient awoke. His pain had gone and he ate a hearty support an amused himself in whistling and a song.\n\nTwo days later, Denis gave him another transfusion even larger than the first. As soon as the blood began to enter his veins, Mauroy complained about the same feeling of heat travelling up his arm.\n \nOn December 22 1818, James Blundell gave what is recognissed as the first transfusion between humans - he injected 12 - 15 ounces of blood taken from several assistants into a patient who was dying of internal bleeding. The man rallied for two and a half hours before expiring. Next Blundell and a colleague injected six ounces of blood into a woman who was bleeding to death after a placental haemorrhage whilst giving birth. The fresh blood had no resuscitative effects. He gave two more transfusion without apparent benefit, making four failures in a row. Finally, Blundell and a colleague injected 6 ounces of blood into a woman who was bleeding to death after a uterine haemorrhage. "I feel as strong as a bull" she told them and recovered. Altogether Blundell transfused 10 patients over and 11 year period, five of whom survived.\n\n\nRegarding your early transfusion - impossible that  it had any effet on our current platelet count.

I give blood all the time but I never have gotten paid for it. It isn't unheard of thugh. Otherwise, I've always had a good experience with it. You could pass out and depending on the person doing it you could get bruising around the area and there are always very small risks of infections. It's bad if you're anemic but they test for that before hand. If you d, be sure to eat first fruits/grains and sweets are good and they usually provide cookies. Also drink a lot of water or juice. The only things that have ever happened to me was being really tired for like an hour afterwards.

There always seems to be a new breakthrough.  Little by little traditional cancer research is gaining ground.  As far as soon?  That would take a major breakthrough.  But look at the rise in technology over  the past 100 years, and then the past decade.  We have not only more educated and then knowledgeable brains working on it, but think about the knowledge that isn't being lost now when someone  in the research field dies.  You don't have to go searching for a book for answers, it's right there on a computer.  Quick access has made knowledge so readily available that the rise in medical technology should continue to spike off the charts.   So, at the rate it's going the past predictions of stating a cure may be found in 50 years could be reduced to "some time soon"er than anyone thought.

I almost died when I had a blood clot operation a few years back, on the operating table, that was an experience I will never forget.  Ever since then I have not feared death because I felt peaceful when it happened, not that I want to die now, but when it is my time I don't have fear and I will be with my family and friends.  :)

Have you thought about Gastric Bypass Surgery??

That is the new theory:\n\nNot long ago nearly all cases of splenic trauma were treated by laparoscopy, opening the abdomen, and by splenectomy, the surgical removal of the spleen. This approach resulted from the difficulty in assessing the severity of the injury, the potential dangers of shock and death, and the beliefs that the spleen healed poorly and that it was not an important organ. Nowadays, improved techniques of diagnosis and monitoring, as well as understanding that removal of the spleen creates future risk of a lowered capacity to fight infection has modified treatment approaches. Research over the past two decades has shown that the spleen has high healing potential, and confirmed that children are more susceptible to infection after splenectomy (post splenectomy sepsis, PSS). PSS has a mortality rate of over 50% and standard procedure now avoids splenectomy as much as possible. Adult splenic trauma is treated by splenectomy more often than children's; for unknown reasons, the adult spleen more frequently spontaneously ruptures after injury. Adults are also less susceptible to PSS.   http://www.lifesteps.com/gm/Atoz/ency/splenic_trauma.jsp

I also had the surgery about 6 years ago now, so I imagine that technology has greatly improved since then. I really didn't experience any pain with the procedure, but it was a little weird. It worked great and is still working. Usually they tell you you can't do certain things for like a month afterwards while your eye heals up completely, but I suppose it depends on what type of surgery you are getting (they have different kinds now.) I'd say go for it. It's great not to have to wear glasses or contacts.

I'm not sure about cars in our pockets, but nanotech is already happening, and yes it is changing our lives. In its simplest form, materials tailored at the nanolevel (a primitive nanotech) are already in stores. Nanomedicine, especially lab-on-a-chip technology is partially available and promises to revolutionize the way we do medicine. I don't know about some of the crazier promises (smart fog and such), but research at the nanoscale is changing our lives and will continue to do so.

No.\nDonating blood is a social good and the activity makes people understand the nature of social goods.

Theres too much it can do! I think the world is using mostly lasers for surgeries now because it is safer and more precise.\n\nWe use lasers for corrective eye surgery, to get rid of hair on our body permanently...and now theres liposuction with lasers!\n\nIts used widely for cosmetic surgery.\n\nOther uses are for reading bar codes, for laser tag games, virtual games, and to read discs and cds. Its limitless!

Experiments have been done in order to design dialysis machines.  Also experimentation has been performed on newly dead humans in order to know how much formaldehyde solution would be needed to embalm bodies of different sizes.  Results for this kind of information leads to the data at the reference below (the 4.4 to 5.0 liters answers).  If you are asking if it is possible to find out the exact volume of blood in a specific living person, I do not know if the technology is currently available.

I agree on corneal transplant. Its an immune privileged site due to the absence of blood vessels so less exposure to circulation immune factors. \nThe operation itself is pretty technically demanding though.

There is no doubt that medical technology will continue to advance. But it is likely that the law of diminishing returns will (or maybe has) limit the improvements that such technology will bring to any patient or humankind overall.\n\nWhilst we still have rampant infective diseases such as Malaria and Tuberculosis decimating 3rd world countries and entire generations dying from malnutrition, we need to ask ourselves if gadgets that bring a little bit of extra function to a small number of people are really progress, or perhaps just ignorance?

Ask your doctor if it will have any side effects or long term issues. Personally, that sounds like fun, I love the head rushes you get after giving blood, I have never fainted though....

Are there any known side effects of blood donation?\nNo. Till date, there has been no medical proof of the side effects that blood donation might bring. Many have gone through the process without a hinch and from then saved the lives of million others.\nBlood donation is quick and safe and does not cost you a single cent.\n\nI suggest you discuss this problem with your doctor.

I don't think they've been doing them long enough to know. Technically there might not be too many issues considering the types of surgery around now. I think the biggest issue is the psychological impact on the patient - I am sure many people would not be able to cope as our appearence is so intrinsic as to who we are. Also I think it unlikely there will be many donors and it will be very difficult for the bereaved to come to terms with the possibility of a loved-ones face being used by someone else.
