Blood transfusion process and precautions

Blood is an important component of the human body. All the nutrients needed by the human body are achieved through the circulation of blood. When some people are involved in traffic accidents, there will always be heavy bleeding. In this case, they need blood transfusion, and blood transfusion is something that people need to pay great attention to. The following is an introduction to the blood transfusion process and precautions.

(1) Before blood transfusion, the appearance of the whole blood must be strictly checked to see if the blood bag is damaged or leaking, and whether the blood color is up to standard. The patient, cross-matching report and the blood to be transfused must also be carefully checked to see if they are correct, including the patient's and blood donor's name, gender, ABO and Rho (D) blood type, results of the cross-matching test and antiglobulin test, blood bag number, blood type and blood volume, etc. Two people should check to ensure that everything is correct before transfusion.

(2) When transfusing blood, the doctor should go to the patient's bedside to verify the medical record number, patient name, blood type, etc. After confirming the identity of the recipient, the blood transfusion should be performed using a standard transfusion device equipped with a filter (the filter mesh has a pore size of approximately 170 microns and a total effective filtration area of ​​24-34 cm2, which can filter out aggregated platelets, white blood cells and fibrin that may be present in blood and blood component products).

(3) Blood should be taken out of the refrigerator immediately before transfusion and should not remain at room temperature for more than 30 minutes. Gently mix the blood in the blood bag before transfusion to avoid violent shaking. No other drugs should be added to the blood. If dilution is required, only normal saline for intravenous injection can be used.

(4) Flush the blood transfusion line with normal saline before and after blood transfusion. When continuously transfusing blood from different donors, after the previous bag of blood is completely transfused, flush the transfusion device with normal saline via intravenous injection, and then continue transfusing the next bag of blood. (5) The blood transfusion process should start slowly and then speed up. The infusion speed should be adjusted according to the patient's condition and age. The recipient should be closely observed for any adverse reactions to the transfusion. If any abnormal situation occurs, it should be handled promptly. During the first 10-15 minutes of transfusion or when the first 30-50 ml of blood is transfused, medical staff must closely monitor for any adverse reactions. If any adverse reaction occurs, the blood transfusion must be stopped immediately and reported to the responsible physician for timely diagnosis and treatment. At the same time, the blood transfusion department or blood bank should be notified to conduct necessary investigation into the cause. Usually, it is not necessary to warm the blood for a transfusion.

(6) After blood transfusion, store the blood bag in a refrigerator at 2-8°C for 24 hours for inspection in case of unexpected situations.

(7) After the blood transfusion is completed, the medical staff will fill out the blood transfusion reaction investigation receipt item by item and return it to the blood transfusion department for safekeeping on the second day after the blood transfusion is completed. The blood transfusion department submits monthly statistics to the Medical Affairs Office (Department), and the responsible physician records the transfusion information in the medical record.

(8) After the blood transfusion is completed, the medical staff will attach the second copy of the blood transfusion form to the medical record.
