Can blood be frozen and reused later in life?

First of all, I don't think you can actually freeze it without damaging the blood. If we could somehow keep our own blood at home, there are really no needs for it. Most blood needed is all at hospitals. Surgeries and injuries are the main causes for blood...Plus, if you had it at home, you wouldn't have the right equipment or knowledge to use the blood. Hope this helps!

Well, a unit of whole blood donated at a place like Carter or the Red Cross will usually be divided into its parts.  The plasma part is either used for as fresh frozen plasma to increase blood volume, or treat bleeding disorders.  It can also be used to make cryoprecipitate - also to treat bleeding disorders.\n\nMany reagents and controls used in laboratories are made from human plasma, like for Coagulation, blood bank (anti-A, anti-B, anti A,B, anti-D, etc. . . )

They can, but through faith choose not to.  It should be mentioned that only 13% of those refusing blood are witnesses.  The Bible says the blood is the soul, so by taking a blood transfusion, you are infusing someone else's soul into yourself.  The Bible also teaches not to take in blood.\n\nMany great medical achievements have happened as a result of their refusals.  Doctors had to develop methods to avoid excess blood loss, always a good idea.  UCLA now does bloodless liver transplants.  \n\n100% of people taking blood experience side affects.  Blood transfusions lowers the immunal response, with large transfusions used to shut down the immune system for transplants.  The immunal response is a lot like that of AIDS.  If you get sick after a transmission, its with a rare illness, not a common one.\n\nIn England, the blood supply is no longer considered safe, due to mad cow disease.  Anyone under 18 can only receive a transfusion of blood imported from America.

I think you should be able to do that, but check with the local blood donation service please.

Blood transfusions are given I.V.  I don't think this usually counts as "surgery" unless a cut down is needed to insert an I.V. when it can't be inserted normally.  The other two...blood vessels and heart transplants are done surgically almost routinely these days.  Every time a viable heart is donated, there is someone in need to receive it.  During a cardiac by-pass surgery, blood vessels are taken from the leg and used for by-pass.....very, very routine.  Blood/blood products (plasma for instance) tranfusions?  Done everyday in almost every hospital during & after surgery and/or if someone has an anemia problem....

The amount of some materials in the sample can be changed by chemical reactions, including those that occur inside cells.  The rate of many chemical reactions is decreased by lowering the temperature.\n\nFor example, blood for "blood gases" is placed on ice, and rushed to the lab.  There, it is injected, from the original syringe, into the testing machine.  One of the analytes is oxygen; the loss or gain of oxygen must be minimised.  Thus, the cells are chilled; WBC use oxygen.  The blood is not decanted from the syringe into a tube, for transport, as it may equilibrate with air.\n\nCooling also reduces changes in pH of the blood, which would otherwise result from metabolism, including that of the RBC.\n\nIn general, it slows the rate of change of the sample, so values from tests reflect what was going on in the patient, at the time it was taken.

You are talking blood donation I assume? When one donates blood, it is done in a closed system. There is a primary collecting bag with 2 satellite bags off the side. No air must be introduced.\n\nThe donated blood is given a light spin, this will separate the red cells from the plasma rich platelets. This platelet rich plasma is then transferred to the first satellite bag. The RBC bag is separated from the satellite bag using a dielectric sealer, so to keep air out, and keep it a closed system.\n\nThe bag of platelet rich plasma is then given a hard spin, so to separate the platelets from the plasma, the excess plasma is allowed to flow into satellite bag #2, leaving just enough plasma in the platelets to suspend. Bag 1 is pooled platelets, Bag 2 is plasma. The two bags are separated again by the dielectric sealer to keep air out again keeping the integrity of the closed system.\n\nBag 1 can be kept at room temperature for up to 5 days.\nBag 2 will be frozen. Frozen it will keep up to one year.\nHowever once you thaw it, you must use it. You cannot re-freeze.\nWhere I work, thawed FFP is good for up to 5 days.

Donating blood may reduce risk for heart disease, and stimulates the generation of red blood cells. In patients prone to iron overload (e.g. due to hemochromatosis), blood donation prevents the accumulation of iron.\n\nAnecdotally, elderly people in good health have reported feeling invigorated by giving blood on a regular \n\nYou'll have  most happiness that you helped someone.

To transfuse, or not to transfuse ... This is a Very Personal decision! ...\nAlthough I Don't mind others knowing what mine is on this matter, for now I  would rather share the Reasons for it being what it is ...\n\nSo here are links to the Reasons behind my decision:\n(Links to other subheadings are found on each Web page in the group.)\n\nThe detailed information in the brochure:\n\nHow Can Blood Save Your Life? \nBlood - Vital For Life \nBlood Transfusions - How Safe? \nQuality Alternatives to Transfusion \nYou Have the Right to Choose \nThe Blood That Really Saves Lives \nJehovah's WItnesses - The Surgical/Ethical Challenge - Appendix #1-\nFrom: Journal of the Americn Medical Association.\nBlood: Whose Choice and Whose Conscience?  - Appendix #2 -\nFrom: New York State Journal of Medicine.\nhttp://www.watchtower.org/library/hb/index.htm\n(Use the links on the Left of the Web page to access the rest of the brochure.)\n\nOne of the points that has Really stuck in my mind from that brochure, (I think it was this one) is that stored blood CAN'T TRANSPORT OXYGEN until MANY HOURs AFTER TRANSFUSION!  ...  (Isn't Transport of Oxygen' one of the Main reasons they Claim a transfusion is Necessary? ... So, in such a case, isn't the transfused blood Only functioning as a volume expander?) ...  So, you might say that a transfusion actually 'Dilutes' one's blood (blood (where oxygen is concerned)  making it Less Capable to do that job ...  Also, that applies to All stored-blood, even Autologous (one's own blood, stored before an operation)!  ...  Even if we were to disregard all the infections, and the mislabelling-mishandling of the blood that often happens, can You see good reason to risk a transfusion, when so many, Much-Safer alternatives exist -- some which Carry Oxygen IMMEDIATELY?\n\nRead on for more info:\n\n"Nonblood Treatment — What Experts Say"\nhttp://www.watchtower.org/library/g/1999/3/8/article_01.htm\n\nBloodless Medicine and Surgery - The Growing Demand : \nPioneers in Medicine \nBlood Transfusions \nThe Growing Demand \nSome of the Methods \nThe New "Standard Care"?\nhttp://www.watchtower.org/library/g/2000/1/8/article_01.htm\n(Use the links on the left of this Web site to access all of these listings.)\n\nJehovah's Witnesses Instrumental in Heart Surgery Advance\nhttp://www.watchtower.org/library/g/1996/1/22/instrumental_in_advance.htm\n\n ...

Forgive me for pointing this out, but survival is possible.\n\nOhter things can be used to maintain circulating volume: crystalloids (like saline) and albumin are the main ones.  Certainly, if you don't get transfused when you need it, you will have some real trouble with anemia, and with oxygen transport--but certain religioius groups, notably the Jehovah's Witnesses, refuse blood transfusions, no matter what.  They often endure more prolonged recovery because of that choice, and certainly many of them die when they would probably have survived with the transfusion, but the transfusion refusal is not a guarantee of death, even in extremely grim situations.\n\nIn longer term situations, the recovery can be accelerated by using erythropoetin or an erythropoetin analog to accelerate production of red cells; this is slower than transfusion, but it has rescued a lot of people who refused transfusions.

Well, the other reply was correct about any anticoagulant added having to be safe; not cause complications for the recipient of the blood, but wrong about chilling being able to stop blood coagulation; it is not very effective.\n\nWhat is wrong with the present additives?  AFAICR, they add glucose and citrate and adenosine.  The citrate can be metabolised by the recipient, as food energy, so it will not cause trouble.  It works well, AFAIK.

Certain diseases would prevent you from being a donor, specifically if you'd ever had hepatitis.\n\nThe general rules for donating blood when one is taking insulin or other medication that may cause allergic reactions seem to apply. \n\nWith possible concerns of mad cow disease (bovine encephalopathies), there may also be some general rules about avoiding any contact with beef product of any kind. Since bovine insulin might have some slow virus contamination, this would be a conservative recommendation to avoid any possible cow products of any kind.

There is a medication called "fresh frozen plasma" that can be given to rapidly reverse warfarin in most situations.

Dont take the item out of the body, it will cause internal bleeding and possibly cause more damage than needed..

You can donate hole blood 4 times a year more if it is a must because of time and place you can give more often But it is not recommended or done except under dire circumstances. If you are giving plasma often you are receiving replacement blood products. It is a give and take. There is a reason you are asking and you probably all ready know the answer good luck.

I work at a blood bank and I have never seen anything get past our lab it is possible but rare. Most hospitals make sure that the centers that they receive blood from has excellent track records.

Probably not until the problem of cellular damage by crystalline ice is solved. Ice crystals form inside cells and burst the cells, causing damage. While live cells like sperm can be frozen in glycerol (a thick liquid that prevents crystals from forming) it is another matter to freeze a whole body. Today, no one has frozen a whole animal and revived it from being frozen.\n\nNot only that, freezing causes massive systemic shutdowns of body systems (ie, you freeze to death) so any suspended animation method would require the ability to reanimate or to avoid death in the first place.\n\nMy guess is that suspended animation will not be by freezing but some other method.
