Biological knowledge, blood transfusion should generally be transfusion? For the principle? 30

Blood transfusion is generally based on the principle of transfusion of blood of the same type.

Blood transfusion is generally based on the principle of transfusion of blood of the same type. If there is no blood isotype, blood type O can be transfused into all blood types, and only type O can be accepted. AB can accept any blood type, only can enter can enter A, can enter B, can accept A, can accept B, O.

Pure handwriting, look at o(o

The commonly used ABO blood group system is the main one, and it is best to receive blood transfusion of the same type, but type A and B can also receive a small amount of AB type when ischemia. AB universal blood supply, type O is universal blood supply, but large and frequent transfusions are not recommended. There is also the need to consider the rh blood group system, and the negative can accept the positive for the first time.

Later it will be fatal.

Generally, the principle should be to transfuse blood of the same blood type, but if the blood of the same blood type is insufficient, a small amount of blood type O can also be transfused instead.

In addition, type O blood is universal blood.

In general, it is advisable to transfuse the same blood type, and the blood types that can be transfused correspond to the following as a a o b b o ab a b o o

Blood types are generally divided into four types: A, B, AB and O, and all blood types can be transfused with type O, and only type O can be accepted. AB can accept any blood type, only can enter can enter A, can enter B, can accept A, can accept B, negative can enter positive, but positive can not.

a.Transfusion of blood of the same type, i.e., neither the primary and secondary sides of the cross-matched blood coagulation.

b.In an emergency, Sakura may be transfused with a large amount of blood type O to recipients of other blood types.

c.Blood transfusions can be given as long as the main side of the cross-match blood does not coagulate.

d.As long as the blood type is the same, there is no need to cross-match.

e.The first blood matching was matched and the blood transfusion went smoothly, and the second time the blood of the same donor was received, there was no need to do Zhixiang cross-matching.

Correct Rental Bundle Answer: a

Answer] :d item A is incorrect, and it is possible to contract diseases if the blood transfusion equipment is not clean during the transfusion process. Item B is incorrect, according to the "Regulations on the Management of Blood-sensitive World Products" formulated by our country, the blood routine items of blood donors should also be tested in emergency situations to avoid infection.

Item C is wrong, blood transfusion is generally performed at the time of ischemia of the patient, and routine blood transfusion is not required to enhance resistance and nutritional supplementation. Item D is correct, and the component blood transfusion can be used for multiple purposes in one blood to save blood sources; reduce adverse transfusion reactions; reducing the incidence of transfusion-borne diseases; Easy to preserve, easy to use; The preparation has a small capacity, high concentration and purity, and a good effect. So the answer is d.

Answer] :d can also contract diseases during blood transfusion. Exclusion a.

Blood type testing must be carried out before blood donation and blood transfusion to ensure that the blood type is compatible. Exclusion B. Although the plasma of whole blood contains albumin, immunoglobulin and a variety of antibodies, the content is not much, which does not play a role in enhancing resistance and cannot solve nutritional problems.

So item c is wrong. A blood transfusion method in which only the necessary blood components are transfused into the patient's slag is called component transfusion. Component transfusions can improve blood utilization and efficacy.

In addition, because it does not infuse ingredients that patients do not need to be required by Nokai, it does not increase the burden on the heart. Therefore, the answer to this question is D.

Answer]: Blood transfusion can improve circulation, increase oxygen-carrying energy, improve plasma protein, and improve immunity and coagulation function.

The principle of blood transfusion, based on the principle of transfusion of the same type of blood, first of all, it is necessary to scientifically analyze the condition and insist on seeking truth from facts. For some people who can lose but can not lose, they should insist on not losing; For those who really need it, they should insist on an appropriate amount of infusion; For the appropriate amount of transfusion, the ingredient blood hand or transfusion should be preferred.

Answer] :d can also contract diseases during blood transfusion. Exclusion a.

Blood group testing must be carried out before blood donation and blood transfusion to ensure that the blood group is dissolved. Transfusions that depend directly on the blood type reported by the donor may cause accidents. Exclusion B.

Although the plasma of whole blood contains albumin, immunoglobulin, and a variety of antibodies, the content is not much, and it cannot enhance resistance or solve nutritional problems. So item c is wrong. A blood transfusion or hail blood method in which only the blood components needed are given to the patient is called component transfusion.

Component transfusion can improve blood utilization and efficacy, and because it does not infuse components that are not needed by the patient, it does not increase the burden on the heart. So item d is correct.
