Blood Transfusions
A blood transfusion is when blood or blood-based products are transferred from one person to another. This is often done because of major blood loss from something such as an accident or childbirth, but sometimes because of a disease such as anemia or sickle-cell disease.
772 Questions
What are the Advantages and disadvantages of blood doping?
Advantages: longer endurance in physical activity due to more oxygenated blood being put into your blood stream... (the more oxygen in your blood the longer your muscles will work for)
Disadvantages: risk of any diseases passed through blood and low blood flow leading to possible heart failure
Can a male be given female blood?
It may be possible actually, you might want to ask a doctor though to be positive. All I know is that females have one more rib than males but Im not sure about different organs. I am sure it has happened in the past.
Yes males can donate organs to females, it has happened many times and the other way round too. By the way males and females have the same number of ribs.
What does a transfusion attempt to replace?
A blood transfusion usually replaces blood that has been lost through bleeding due to surgery or injury.
Sometimes it's used if the body can't produce enough blood on its own due to disease.
What factors determine the compatibility of blood types for transfusion?
Blood type is determined by the type of antigen
What blood type can type O people receive?
Noop.
Type O can donate to most other groups (Rh factor compatible), that's why Type O blood (especially O-Negative) is in such great demand at hospitals--they are the universal donors.
What can happen if you receive the wrong blood type?
Some symptoms of a mild transfusion reaction from getting the wrong blood are chills, fever, dizziness, flushed skin, back pain, and the presence of blood in urine. These symptoms can manifest when a person is receiving the transfusion or shortly after. In some cases, a person also can have a severe transfusion reaction that can cause symptoms like shock, decreased blood pressure, and a rapid pulse.
Can individuals with Type AB blood may receive transfusions from individuals with Type O- blood?
Yes- the AB blood group is known as the 'Universal Recipient', since they can receive blood from any group. Blood group O is known as the 'Universal Donor', since all other blood groups can receive this type, but people with group O can only receive from other group O types.
Why is saline used in blood transfusions?
Saline is used to prime the IV line before the blood runs through the line. It is used after the transfusion to flush the IV line.
Why do Jehovah's witnesses not allow blood transfusions?
Many places in the Hebrew scriptures (Old Testament) humans are told not to eat blood, God forbids eating meat without first draining the blood, and Acts 15:20,29 states that we are to "....abstain from blood....."
If your doctor tells you that you are to abstain from alcohol or dairy products, lest you should die, would you consider injecting alcohol or dairy products into your veins? Of course not. You would avoid those products all together in all forms. Therefore, JW's do not accept blood in ANY form - whether in meat or anti-venoms, or transfusions of their own or anyone else's blood. To "abstain from" literally means to "voluntarily hold oneself back from." The subject of Jehovah's Witnesses and blood transfusions has been a subject of much misunderstanding on the part of non-witnesses.
JW's do not accept blood transfusions based on the Bible's command to "abstain from blood."(Acts 15:29) However, we DO accept transfusions of NON-blood substitutes.
Hospitals around the world are recognizing that non-blood medical treatment is safer than using human blood. More and more hospitals are becoming entirely "bloodless" because of the many HEALTH RISKS from using real blood, such as, tissue rejection and infection from hepatitis, aids, and hundreds of other blood borne diseases. "A growing number of hospitals are offering alternative 'bloodless' surgery," reported The Wall Street Journal. "Originally developed to accommodate Jehovah's Witnesses," states the journal, "the practice has gone mainstream, with many hospitals promoting their bloodless-surgery programs to the general public."
Even people who are not JW's are claiming to be such just to keep from receiving blood transfusions, claims The Winnipeg Sun of Canada. That newspaper says, "A growing number of hospital patients afraid of catching AIDS or developing other blood related problems are posing as Jehovah's Witnesses," states the article. "Church elders have discovered more than a dozen impostors while doing their hospital rounds." One woman said she pretended to be a Witness so that she would not have to fight with the doctors over the treatment. "The reason I refuse blood is not religious," she said. "When you take someone else's blood there's no guarantee that you'll be any healthier. It could make you sick or even dead." One impostor was discovered by a chaplain who saw the man sitting in bed smoking a cigar. The man sheepishly admitted that he wasn't a Witness. "I just don't want a blood transfusion," he said. "I'm a doctor."
Along with hospitals, now thousands of doctors worldwide are practicing non-blood medical treatment, not just for Witness patients, but as their preferred method for ALL patients.
The dangers from blood transfusions are so great that the reference work Dailey's Notes on Blood says: "Some physicians maintain that allogenic blood [blood from another human] is a DANGEROUS DRUG and that its use would be banned if it were evaluated by the same standards as other drugs."
Our position though, is governed by the Bible and our resolve to obey our creator who tells us to "abstain from blood." Our position is not "complicated". Simply put, we do not accept whole blood or any of it's four main parts, plasma, white blood cells, red blood cells, or platelets. But, there are hundreds of blood fractions that an individual's conscience may allow them to accept. An individual may view small fractions of blood components as not being blood, in the same way that a fraction of a cake such as sugar, is not the cake itself. I personally do not find that complicated, and I know of no other Witness who finds that complicated either.
The reference to Genesis 9:4 where it says not to 'eat the blood' leads some feel that this simply means not to take blood into the mouth. If you were told not to eat sugar (possibly due to diabetes) would you then assume that you would be okay if you were to inject it directly into your veins? That would not be reasonable. Further, the command to the Christian congregation was to "abstain from blood," as Acts 15:29 clearly states.
ANSWER From Another Jehovah's Witness:Quite simply, because Jehovah God and Jesus' 'faithful and discreet slave' class tells us not to, and therefore we are obeying Jesus' direct commands as explained in our journals.Watchtower 1959 1st May p269
''To hold to the headship of Christ, it is therefore necessary to obey the organization that he is personally directing. Doing what the organization says is to do what he says. Resisting the organization is to resist him.''
If the Society had 'new light' based on Biblical research and intense prayers, and stated that we could have blood transfusions if we so chose, then we follow their direction. The chances of that are about as slim as IF it was ever possible to discover that it's OK to steal; to commit adultery; then we would publish the new information, and we'd all go out and steal, and commit adultery. I would suppose that would never happen; emphasis on the word 'never'.
This is amply demonstrated in our beliefs on organ transplants. At one time we used to refuse organ transplants as they were considered to be cannibalism. (WT 67 15th Nov). Then in 1980, 15th March WT, Jesus and Jehovah saw fit to direct us that it was now ok to have an organ transplant, if one so chose.
Also, some witnesses' consciences may allow them to accept blood fractions, as long as these have been separated completely from any of the four main blood components.
Genesis 9:4
But flesh with its life, its blood, you shall not eat*.
Leviticus 17:14
For as to the life of all flesh, its blood is with its life: therefore I said to the children of Israel, "You shall not eat* the blood of any kind of flesh; for the life of all flesh is its blood. Whoever eats it shall be cut off (die)."
Acts 15:19-20
"Therefore my judgment is that we don't trouble those from among the Gentiles who turn to God, but that we write to them that they abstain from the pollution of idols, from sexual immorality, from what is strangled, and from blood.
(World English Bible - public domain)
* Note: Officially, transfusion is considered being 'fed' blood, which is why the commandment not to eat blood is thought to be relevant.
God's people worldwide show respect for blood. Jehovah (God's name) speaks about blood in Genesis 4:10 after Cain had killed Abel and thought that he would get away with it. In all reality Jehovah saw the whole thing. Jehovah says in that scripture, "Your brother's blood is crying out to me from the ground." When he said blood he was referring to Abel's life. This meant that Abel's life, or blood, was crying out for Jehovah to set things straight as it were.
Another instance was shown in Noah's day after the Flood. Did you know that before the Flood people only ate fruits, vegetables, grains and nuts? Well they did until the Flood came in about 2370 BC and shortly after the water had drained from the earth Jehovah had told Noah and his family, "Every moving animal that is alive may serve as food for you." This meant that they could not eat animals before 2370 BC. However, Jehovah was not done speaking. He went on to say "Only flesh with its soul [or, life] -it's blood- you must not eat. (Genesis 1:29, 9:3,4) In fact they were told that they could eat the meat of an animal but they had to pour the blood back into the ground, symbolically returning the animal's "life" to Jehovah.
Later in the Bible, Acts 15:28,29 and 21:25 tells us to keep abstaining from blood. In God's eyes, doing this is just as important as our avoiding idolatry and sexual immorality. And abstaining from blood means not taking it into our bodies AT ALL. Similar to if your doctor said you would die if you did not cut out alcohol from your life. Would you reply, 'well I can still have it injected and not drink it'?
I advise you to obtain a book (free of charge) which we publish that explains all of this information and more in greater detail. It's called "What Does the Bible Really Teach?"
You may obtain one in almost any language at your local congregation, or call and ask a Witness to bring one to you. All you have to do is ask and they can get you one.
IMPORTANT ADDENDUMFirst, let's be clear. Jehovah's Witnesses do NOT refuse the transfusion process, just the use of blood.
There are numerous non-blood substitutes that can be transfused into a patient, such as Ringers lactate, saline solution, or other blood volume expanders. Doctors will tell you - the amount or quantity of liquid cursing through one's veins is actually more important in saving one's life than adding blood cells.
The reason that we refuse blood is because of God's command which is repeated in several places in the scriptures. The Bible often states not to "eat" blood. We understand that means not take blood into the body at all. Acts 15:28,29 simply says to abstain from blood. Again we understand that in the same way that if a doctor told you to abstain from alcohol, he would mean simply not take it into your body at all through ANY means, whether through the mouth or intravenously.
Because of our stand on this issue, we have experienced many benefits. For example, my own father had triple bypass surgery a few years ago using non-blood medical management. He recovered faster than normally expected by patients having this type of surgery, and was back home several days before the prognosis would normally be.
The medical profession has made great strides in non-blood medicine, largely due to the refusal of Jehovah's Witnesses to accept blood. A growing number of hospitals are going "bloodless" because they are finding the the treatment is better. Patients are recovering faster with less chance for infection.
The part of the 'faithful and discreet' slave that make up our Organization's Governing Body help us to understand the Bible's command not to have blood transfusions, and thus obey Jehovah, as explained in the following quote:
Watchtower 1959 1st May p269
''To hold to the headship of Christ, it is therefore necessary to obey the organization that he is personally directing. Doing what the organization says is to do what he says. Resisting the organization is to resist him.''
So, in conclusion, Jehovah's Witnesses accept all kinds of different medical treatment but adroitly refuse blood transfusions because, according to the Bible, blood is sacred and absolutely not to be put into a human's body in any way.
Opinion:The command is clear in Acts chapter 15 verse 28 and 29 to "abstain from blood" so, although we accept non-blood alternative treatments, we refuse to be transfused with blood... Compare Genesis 9:3, 4; Leviticus 17:10-14.This does not mean we are making a foolish or uninformed decision. We want quality medical care and for doctors to do whatever they can do to save us and care for for us. We want them to provide us with the best alternative treatments to blood transfusions, and there are many quality alternatives, which as it turns out are both safer AND often far more beneficial in other ways than treatment with blood.
Since the Bible makes no clear statement about the use of minor blood fractions or the immediate re-infusion (in a closed circuit) of a patient's own blood during surgery, a medical process known as blood salvaging, the use of such treatments is a matter of personal choice.
The answer below this containing the misapplied quote from the Watchtower 1959 1st May p269 is erroneous. Although we are to follow the instructions of the faithful and discreet slave, because that is who Jesus left to preside over his "household" according to Matthew 24:45-47, we do not do so blindly, nor in opposition to plain Scripture. Acts 15:28, 29 says "Abstain ... from blood" and nothing the faithful and discreet slave class says changes that. The faithful slave will NOT teach against the Bible. If certain ones of them did begin saying things that are out of harmony with Scripture, then they are part of the ones Jesus spoke of in Matthew 24:48-51. Notice, Jesus appointed one Slave, but the actions of that slave determine whether he is faithful or wicked.
Another AnswerMany JWs have needlessly died because the governing body considers blood transfusions to be "eating blood." Of course, their view on this has recently changed to allow some uses of blood fractions. But the governing body is careful to explain its new understandings on blood to its followers. Another OpinionThe exact stance taken by Watchtower has varied over the years. Transfusion (and also organ donation) were even branded as a form of cannibalism at one time in the past. They relaxed their position in 2000. Although whole blood, and the components thereof (red & white cells, plasma, platelets) are still considered forbidden, followers are advised to use their own discretion when accepting or rejecting treatments which make use of fractional parts of these components (such as hemoglobin, interferon, or albumin).Indeed, many Jehovah's Witnesses choose not to follow Watchtower's interpretation of the above scriptures, and will in fact accept transfusions.
No, They are dead-set against it. this is extremely high risk as people have died from not having blood transfusions. They quote Bible passages out of context- as let"s face it Blood transfusions only became a medical practice- of a practical, everyday sort- in the twentieth century. the first Blood Bank was opened in l937 Specially modified buses rigged for donations of blood called Bloodmobiles came much later.
The Absolute point:
Most people in professed Christian faiths continually re-oath themselves over and over again on the issue of Jesus Sacrificial Blood, while they consider other sources of life saving measures or other sources of blood inconsequential in accepting these. A Jehovah's Witness holds the Blood of Christ so much in high esteem, they will not under any circumstances usurp that Oath. Meaning they will do the utmost to preserve lives including the one attached to keeping this Oath without marring it with other sources physical or otherwise of blood. You can call it "A lifelong commitment to keep ceremonially clean in the sight of God." Acts 20:26
It would be hard to do so accepting blood which are full of personal ills, not that they view that they are perfect, but rather as showing to God their will to continue on living as clean as possible. Some would argue since perfection is not an issue what would be the point? Giving in and giving up on the issue of cleanliness, is not an option for a Jehovah's Witness, he or she will continue to fight for it showing God the most high level of the will to live that that person has.
Side Note: The class of the opinion poles that spread and generate falsehoods and innuendos about the Jehovah's Witnesses are due to it's fickle attitudes tied to prejudice. Matthew 11:16-19 That said, it is strange to me that actual known dangerous cults some are and were using blood, now today the reverse holds true when they accuse Jehovah's Witnesses as a dangerous cult while these Jehovah's Witnesses fervently AVOID using blood in their lifestyle.
_______________________________________________________________
the bible plainly states to abstain from blood.
also many doctors are started to use alternative to blood because of the harm that it causes. this article is not even from a JW source:
More than half of blood transfusions may do more harm than good, with some patients facing a six-fold greater risk of dying following surgery because of transfusions, doctors warn today.
Fears over the safety of blood transfusions have prompted some physicians to recommend they are used only as a last resort, with hospitals urged to be more selective over which patients receive blood. According to a report in New Scientist today, the National Institutes of Health, the US government's largest medical funder, has launched a review into the safety of the procedure. Bruce Spiess, a cardiac anaesthetist at Virginia Commonwealth University in Richmond, America, told the magazine: "Probably 40%-60% of blood transfusions are not good for the patients."
John Wallwork, professor of cardiothoracic surgery at Papworth hospital in Cambridge, said: "We are concerned about blood transfusions for a variety of reasons. We don't want to use blood unless we have to. In heart surgery around half receive blood transfusions, but often they are patients who are sicker or bleed significantly during the operation. It's always a case of balancing the risks."
Answer 1:
Firstly, the 'faithful and discreet' slave are the seven men in Brooklyn that make up Jehovah's Witnesses' Governing Body. This Governing Body of seven men tell Witnesses not to give blood, based on their understanding of Acts 15 and individual Jehovah's Witnesses believe they are obeying Jesus' direct commands as explained in the following quotes:
Watchtower 1959 1st May p269
''To hold to the headship of Christ, it is therefore necessary to obey the organization that he is personally directing. Doing what the organization says is to do what he says. Resisting the organization is to resist him.''
Watchtower 2009 15th Feb p27
''Since Jehovah God and Jesus Christ completely trust the faithful and discreet slave, should we not do the same?''
Although Jehovah's Witnesses do not give or donate blood, some Witnesses' consciences will allow them to accept transfusions of blood that non-Witnesses have donated as long as it has been split into smaller parts that they call fractions.
Answer 2:
If you want up to date and ACCURATE information it is good to ask one who is one of Jehovah's Witnesses rather than asking somene who may be out of touch, not up to date and biased. Jehovah's Winesses have a free public website jw.org that will answer any and all questions you may have about them. Check out the site and in particular at the bottom under LEARN; Answers to Bible Questions
Can you get an STD from a blood transfusion?
No, only the antibodies that fight the virus are found in the bloodstream. The actual virus stays around the spinal cord and your nerve system. It is more of a skin contact disease.
--------------------------- FROM Thomas_answers:
Blood indeed is very precious. The marvelous fluid is indeed unique in that it is really outstanding in what it does for us. The major worth stems around the fact that Christ's blood alone is the cure all, remedy, ransom for all mankind's woes! The amazing worth of Christ's blood is diminished by the abuse of the marvelous fluid by any idea of transfusing , eating (blood sausage etc.) Revelation 1:5 (Expanded Bible) and from Jesus Christ. Jesus is ·the faithful witness [or the faithful one, the witness], the ·first among those raised from [L�firstborn of/from among] the dead. He is the ruler of the kings of the earth. ·He is the One [L�To him] who loves us, who made us free from our sins ·with the blood of his death [L�by his blood].
NOTE THE carefulness we should express to any use of blood: (Acts 15:28,29) Amplified Bible: "For it has seemed good to the Holy Spirit & to us not to lay upon you any greater burden than these indispensable requirments, 29 That you abstain from what has been sacrificed to idols & from (tasting )blood & from eating the meat of animals that have been strangled and sexual impurity, If you keep yourselves from these things you will do well. Farewell"

No answer to disease
Medical science has done much in fighting disease, but the picture is not the rosy one forecast in 1975 by one of the world's leading scientists: "I know of no medical problems we will not be able to solve in the near future." Ten years later, not only is the fight far from being won but it is losing ground on many fronts. Cancer, heart trouble, cirrhosis, diabetes, multiple sclerosis, malaria, sleeping sickness, snail fever, leprosy-all rage on unabated.
Venereal diseases have not succumbed to antibiotics. Stronger antibiotics result in more resistant bacterial strains. AIDS is incurable and spreading-primarily among homosexuals, intravenous drug users, and recipients of blood transfusions. There is no known cure for genital herpes. Chlamydia is an epidemic that annually "afflicts at least three million and perhaps as many as 10 million people." Among other disabilities, it causes infertility.
Newsweek of February 4, 1985, reported: "The United States is currently in the grip of an STD [sexually transmitted disease] outbreak of unprecedented proportions. The statistics are awesome: 1 in 4 Americans between the ages of 15 and 55 will acquire STD at some point in his or her life." The article concludes: "The best protection against STD, it seems, just might be a return to that old-fashioned safeguard: monogamy." This is an answer unacceptable to this world.
What blood types can be donated to a person with type B blood?
Transfusions require either the blood type of the patient or Type O, which is universal.
However, if you know that you are going to have an operation that requires or may require a transfusion, your best option is to donate and "bank" your own blood prior to your surgery. I've done this on 2 occasions in the past for major spinal operations.
The catch is that you need time to bank your blood, but the standards for self donation are relaxed. You also should only consider it for a major elective surgical procedure.
While the medical field professes that the blood supply is "much safer" than in the 80's and 90's when self donation was more popular, there is no way they can guarantee 100% you won't contract anything from transfused blood of another donor.
As an example, during my first spinal operation (cervical fusion C5/6/7), I, like other patients, was given the choice of having bone material for the bone graft needed for the procedure taken from my pelvic area, or the use of cadaver (corpse used for medical purposes) bone. It was believed then that no diseases could be acquired from the use of cadaver bone.
Aside from the creep factor of the thought of having dead-guy parts inside of me (organ transplants are different - they're living tissue), I was never completely satisfied with their assurance that I couldn't get anything from using cadaver bone. The difference between the two is of course with cadaver bone you don't require an additional surgical procedure (concurrent with the primary surgery) and so recovery takes less time. In fact it takes much longer for the hip area to recover than the neck does.
In the end, I opted for the use of my own bone and banked several unit of my own blood. One way they assure you it's your blood being used is that you're required to initial the labels used on the blood bags, and you then verify it in the OR prior to being put under.
Since then, it has been determined that Hepatitis can be transmitted from the use of cadaver bone of patients who previously had it. So much for medical assurances. I've never regretted that decision, even though the recovery took several months longer because of the pelvic bone removal.
Despite what the medical community says, I'm a firm believer in using your own parts and fluids whenever possible for a surgical procedure. Everyone is different though.
But I don't have Hepatitis C either.
A unit of whole blood is 450 milliliters, which is about 0.9510 U.S. pint. ... The adult human body contains roughly 12 units of whole blood.
Why do alveoli got a very good blood supply?
Of course, the lungs receive a full flow of blood straight from the heart, because the entire blood supply must be oxygenated and have it's carbon dioxide removed continuously. The alveolis' function is to provide a large surface area for the gas exchange to take place. These millions of tiny air sacs have a surface covered in very fine capillaries.Their combined surface area is about the same as a tennis court,co-incidently similar to the surface area in the small intestine.
What is an autologous blood transfusion?
An autologous transplant uses the patient's own bone marrow for stem cells. This is done after any cancerous cells are treated with chemotherapy.
Blood thinning drugs are the main treatment. These medications, also called anticoagulants, stop the clot from growing and prevent new clots from forming. Your body will break down and reabsorb any existing clots on its own.
Common blood thinning drugs used to treat are Heparin and Warfarin

Erythropoietin
(EPO) is a hormone produced by the kidneys that stimulates red blood cell formation and controls the rate of the formation through negative feedback.
Erythropoietin
is released in response to prolonged oxygen deficiency.
Is a blood transfusion dangerous?
Yes, many things, blood transfusions can cause death if they give the wrong type, as of wrong blood group or of Rh positive to negative.
Also it is possible to be exposed to a bloodying pathogen such as HIV or hepatitis. Modern testing greatly reduces this risk, but there still remains a small risk. Blood typing/matching errors are extremely rare. There is always a risk (albeit small) any time you receive tissue into your body from another person whether it is blood, an organ, bone, skin, etc.

How the blood enter to the heart?
Let's follow the flow of blood starting at the Aorta, the aorta is the main blood vessle that carries O2 rich blood to the vital organs, organs, systems, extremities, muscles, and most importantly the brain. All the above mentioned use the oxygen and give off carbon dioxide as a by product. The CO2 , carried by the blood travels back to the heartand enters the Right Atrium, another beat of the heart, the b;ood now moves through the tricuspid valve to the right ventricle. Remember, this is oxygen poor blood so withamother beat the blood mooves through the pulmonary arteries, (left & Right), to the lungs. Inside the lungs the blood drops off CO2 and picks up O2 using a process called osmosis*. The blood at the moment has little pressure so it goes back into the heart through the Pulmonary Veins into the Left Atrium. A beat of the heart sends it into the Left Ventricle. Around this chamber is a large muscle called the Myo Cardium and this muscle gives the pressure needed to push this blood oround the entire body.
*Osmosis, the diffusion of water or another solvent through a selectively permeable membrane. This membrane is like a sieve, allowing solvent molecules, which are small, to pass through it, but preventing larger molecules dissolved in the solvent from passing through.
Blood is transferred throughout the body via the heart, this is called systemic circulation. The heart is made up of 4 chambers. The right atria, the right ventricle, and the left atria, and left ventricle. The right side of the heart gets the oxygen poor blood ( the blood that already cycled through the body). The oxygen poor bood enters the right atrim through the Superior vena cava and the Inferior vena cava. When the heart relaxes after a contraction then the blood leaves the right atrium, passes through the tricuspid valve (a flap that seperates the two chambers) and fills the right ventricle. When the ventricle is full the tricuspid valve closes. Now the blood is in the right ventricle, but it is so full the blood has to go somewhere so it pushes through the pulmonary valve and goes to the pulmonary artery then right to the lungs to be filled with oxygen. From the lungs the bood is now oxygen rich (filled with O2). The blodd leaves the lungs by the pulmonary veins and enters the left atrium, as the heart relaxes the tricuspid valve opens and the left ventricle fills with blood. When the left ventricle gets full the blood is pushed through the aorta valve and goes in to the aorta. From the aorta the blood enters into systemic circulation and spreads oxygen rich blood throughout the body. And when there is no more oxygen left in the blood it traveles back to the heart to start the cycle all over.
How much blood is there in 1 transfusion?
Last time I gave blood, they take 470mls of blood, plus four test tubes partially filled as samples for testing. Some tests would be to check I don't have any disease, others for lab tests I suppose.
When is bypass surgery needed?
It depends on the bypass. If you are talking about a cardiac bypass, then it should be done as soon as possible if necessary. A cardiac bypass is necessary if an artery supplying blood to the heart muscle is blocked. If you are talking about gastric bypass, I believe that is solely a recommendation/optional surgery to assist in a weight-loss plan.
So, in short, it depends on the bypass in question.
An adverse reaction would be an unwanted, negative or unfavorable result of an action. Most often used to describe unwanted or negative side-effects of or allergies to medications.
What does the hospital do to someone who lost a lot of blood?
Fainting,coma or even death.
If the loss is not severe then one can recover with rest for a few days and good diet with iron supplements.
Can you get diabetes from touching an infected person's blood?
No.
Type one diabetes is an autoimmune diasease that is non preventable and non curable. It's not an infection so it cannot be 'caught'. Type two diabetes is a generic or lifestyle disease, both preventable and sometimes curable. Also not an infection or 'catchable'.
Why is it important to get the right blood type during a transfusion?
Actually blood group of a person is determined by the antigens(A special protein) present on the surface of all the red blood corpuscels(RBCs) in the body.The body's antibodies do not effect the RBCs of the same type but RBCs with any other type of antigen are attacked by the antibodies and immediately sticking of RBCs begins(called agglutination) causing a great risk to the life of the patient.Threfore, care is taken to match the blood groups of donor and recipient during blood transfusion.
