How can a body reject a blood transfusion?

How can a body reject a blood transfusion?

Antibodies: Antibodies are produced by the body to defend against "foreign" substances, such as bacteria, viruses or cells from another person and generally circulate in the blood. If transfused red blood cells have structures on their surface that are different than those on your own red cells, the body may unleash this army of antibodies to attack and kill transfused cells. ...Read more

Is it possible that after a while a sickle cell patient body starts rejecting blood transfusions?

Is it possible that after a while a sickle cell patient body starts rejecting blood transfusions?

Not really: There's no such thing as "rejecting" blood transfusion. Very rarely, someone can have a severe allergic reaction to transfused blood, with hemolysis (which as a sickle patient you may know a lot about). But this is exactly what blood typing is designed to prevent. If you think transfusions aren't boosting your hematocrit or hemoglobin as much as in the past, discuss it with your doctor. ...Read more

If you have a blood transfusion how long will it take to process the foreign blood out of your body?

If you have a blood transfusion how long will it take to process the foreign blood out of your body?

Probably 120 days.: The foreign blood is not really processed out of your body as much as it is reconverted as it is used. It also depends on what is transfused in the first place be it packed rbc's, fresh frozen plasma, or cryoprecipitate, etc. At any rate, the average life span of a red cell is 120 days, and depending on how old the cells are when transfused it can take up to that long for them to die off. ...Read more

Is it possible for the human body to endure complete blood transfusion?

Is it possible for the human body to endure complete blood transfusion?

Yes indeed!: In fact, exchange transfusion was the treatment of choice that saved many lives of children both with rh disease -- hemolytic disease of the newborn -- back in the bad old days. Today, all of one's plasma can be removed and replaced daily, as in treatment for goodpasture's and ttp. This is an excellent question and still very relevant. ...Read more

Can you tell me for what reasons do the jehovah's reject blood transfusions and what treatments do they accept/reject?

Can you tell me for what reasons do the jehovah's reject blood transfusions and what treatments do they accept/reject?

Bible verses: The sect also used to forbid immunizations, organ transplantation, and aluminum cookware but has reversed their positions. Don't argue with them. It is an ultra-authoritarian sect and members who disagree are "disfellowshipped" and their own families are not allowed to speak to them. JW's may accept certain fractions of blood. Be aware of the terrible pressures these people are under. ...Read more

9 RBC, 39000 platlets, low WBC 6 transfusions and not raising my blood levels, my body won't make or take blood. I am afraid I won't go home, help?

9 RBC, 39000 platlets, low WBC 6 transfusions and not raising my blood levels, my body won't make or take blood. I am afraid I won't go home, help?

Don't give up. EVER: There's one thing I know. That is... I can't predict the future. I care for critically ill patients every day. There are patients that I am sure will die... Then they get better. Then there are patients that I think I will "cure". But a higher power intervenes. Ultimately, I have discovered that life is a dichotomy. Life is very strong... But it is very fragile. Stay strong! And accept help. ...Read more

This: This sounds like thrombocytopenic purpura. It can be caused by a variety of conditions, but sometimes there is no cause identified (in which case it's called idiopathic.) if she is not being seen by a hematologist, she definitely should be. Has she been exposed to heparin? This is a common intravenous or subcutaneous medication that can cause a similar picture in patients who are sensitive to it. ...Read more

Decreased oxygen lev: This is a clinical decision since patients with symptoms of hypoxemia (low oxygen) most likely will not improve until their oxygen carrying capacity (red blood cells and hemoglobin) are increased to support the normal function of the body.
In cases of acute bleeding of 2 or more liters of blood, the patient most likely will need a transfusion (our body has 4-6 liters of blood or 10 pints). ...Read more

Rare: It is rare to have a white blood cell transfusion. White blood cells only live in the blood stream for a few hours and transfusions of white blood cells are more likely to cause fever. If you have low white blood cells, you are usually given a medication that stimulates production of white blood cells by your bone marrow. ...Read more

What are risks now from blood transfusion?

Depends on lifestyle: The risk of aquiring an infection depends on the donor's health condition, and what behaviors he/she engaged in. This is why people are screened before they donate blood. They are checked for temperature, amount of iron, asked questions about general health, and have blood pressure taken. The blood is even screened after donation for things like hiv. Anyone with higher risk cannot donate. ...Read more

Which illnesses require blood transfusion?

Need of blood: Blood transfusions are required when a patient's body can't maintain adequate oxygenation for tissues due to decreased red blood cells. Usually if hemoglobin levels are below 6 g/dl and there are symptoms of anemia or active bleeding, a transfusion maybe required in order to save his or her life. ...Read more

Would a blood transfusion affect immunity?

Would a blood transfusion affect immunity?

Yes: Transfusion-associated immuno-modulation (TRIM) is independent of whether the blood is allogenic, autogenic, or leukodepleted. This has been described since 1973, seen in the improved graft survival in kidney transplant in transfused patients. Some effects include down-regulation of the immune function by decreasing cytokine production, and an increase in T suppressor cell number and function. ...Read more

Plenty: To be able to accomplish a blood transfusion there has to be a blood donor that gives blood to a blood bank, then it is processed and tested before it can be transfused to a compatible recipient. It is a prescribed product and its major indication is the need to increase oxygen carrying capacity in an anemic patient with symptoms of low oxygen. Also platelets or plasma are other products available ...Read more

I guess becuase the: Incomplete transfusion didn't work. In all seriousness I am not sure of the question.
