4_6hrs
What preparation for a lung biopsy does a patient undergo?
Blood tests may be performed before the procedure to check for clotting problems and blood type, in case a transfusion becomes necessary.
Why is the Rh factor especially important with a transfusion?
In all the four basic blood groups there exist two sub-groups called Rh (+ve) and Rh (-ve). The people with the Rh (+ve) blood group have an additional "Rh" facto or the "Rhesus" factor (so named because it was first observed and discovered in the Rhesus monkeys). Whereas the people who do not have the 'Rh' factor are said to have Rh (-ve) blood as in B (-ve) etc. While blood transfusion it is very important to check the "Rh-compatibility" of blood of the donor and that of the recipient, because transfusion of Rh +ve blood to a person with anegative blood group leads to agglutination(clumping) of blood cells thus resulting in death of the person. But it must be noted that transfusion of Rh -ve blood to a person with positive blood group does not harm the recipient.
Why do you check vital signs one hour after a transfusion?
It is to see how well the heart is reacting to the new blood that has been put into the body. And vital signs are always checked whether they just received a blood transfusion or if it is just a regular doctors visit. Vital signs are very important!
Why are blood type and Rh factor checked before a transfusion?
If the blood type of the donor is different from the receivers blood type, the blood type of the revive can attack the different type of blood
Can blood resist to get HIV infection?
.....I have no idea why would you ask this question....HIV transmit because of blood transfusion or blood contact. There is no blood that can resist HIV infection...In fact blood is the best way to get HIV infection. If you are exposed to blood contaminated with HIV...Do get an early check up.
What is the use of blood transfusion?
Blood transfusion replenishes the deficiency of blood in the victim in case of accidents or some diseases that lead to excessive loss of blood from the body that can be fatal to the life of the patients. thus it acts as a life saver BUT it is very important to check compatibility of the blood groups as well as for infections in the blood of the donor and the recipient before opting for a blood transfusion or else the ritual will do just the opposite of saving life by probably taking the life of the recipient.

Transfusion reaction - hemolytic?
DefinitionA hemolytic transfusion reaction is a serious problem that occurs after a patient receives a transfusion of blood. The red blood cells that were given to the patient are destroyed by the patient's own immune system.Alternative NamesBlood transfusion reactionCauses, incidence, and risk factorsBlood is classified into different blood types called A, B, AB, and O.The immune system normally can tell its own blood cells from blood cells from another person. If other blood cells enter your body, your immune system may make antibodies again them. These antibodies will work to destroy the blood cells that the body does not recognize. For example, a person with type A blood makes antibodies against type B blood cells.Another way blood cells may be classified is by Rh factors. People who have Rh factors in their blood are called "Rh positive." People without these factors are called "Rh negative." Rh negative people form antibodies against Rh factor if they receive Rh positive blood.There are also other factors to identify blood cells, in addition to ABO and Rh.Blood that you receive in a transfusion must be compatible. Being compatible means that your body will not form antibodies against the blood you receive. Blood transfusion between compatible groups (such as O+ to O+) usually causes no problem. Blood transfusion between incompatible groups (such as A+ to O-) causes an immune response. This can lead to a very serious transfusion reaction. The immune system attacks the donated blood cells, causing them to burst.Today, all blood is carefully screened. Modern lab methods and many checks have helped make these transfusion reactions very rare.SymptomsBloody urineChillsFainting or dizzinessFeverFlank pain or back painRashSymptoms of transfusion reaction usually appear during or right after the transfusion. Sometimes, they may develop after several days (delayed reaction).Signs and testsThis disease may change the results of these tests:BilirubinCBCCoombs' test, directCoombs' test, indirectFibrin degradation productsHaptoglobinHematocritHemoglobinRBC countSerum creatinineSerum hemoglobinUrinalysisTreatmentTherapy can prevent or treat the severe effects of a hemolytic transfusion reaction. If symptoms occur during the transfusion, the transfusion is stopped immediately. Blood samples from the person getting the transfusion and from the donor may be tested to tell whether symptoms are being caused by a transfusion reaction.Mild symptoms may be treated with the following:Antihistamine drugs (such as diphenhydramine) can treat itching and rash.The pain reliever, acetaminophen can reduce fever and discomfort.Corticosteroids (such as prednisone or dexamethasone) can reduce the immune response.Fluids given through a vein (intravenous) and other medications may be used to treat or prevent kidney failure and shock.Expectations (prognosis)The outcome depends on the severity of the reaction. The disorder may disappear without problems. Or, it may be severe and life threatening.ComplicationsAcute kidney failureAnemiaDiscomfortLung dysfunctionShockCalling your health care providerTell your health care provider if you are having a blood transfusion and you have had a reaction before.PreventionDonated blood is put into ABO and Rh groups to reduce the risk of transfusion reaction.Before a transfusion, patient and donor blood is tested (crossmatched) to see if it is compatible. A small amount of donor blood is mixed with a small amount of patient blood. The mixture is checked under a microscope for signs of antibody reaction.Before the transfusion is given, the health care provider will usually check again to make sure you are receiving the right unit of blood.ReferencesGoodnough L.
