ABO hemolysis can be prevented through strict blood group identification and cross-matching, careful checking and verification, and regular maternity checkups.
1. Strict identification of blood group and cross-matching: during the process of blood transfusion, we should strictly identify the blood group of the recipient and the blood group of the blood donor, and transfuse blood according to the rules of ABO blood group matching; and through cross-matching, we should test the antigen and antibody components in the blood of the blood donor and the blood recipient to see if there are any mismatches that may lead to hemolysis.
2. Careful checking and verification: During the process of blood transfusion, important information such as blood type, identity and volume of transfusion of blood donors and transfusion recipients should be carefully checked and verified to avoid human errors.
3. Regular obstetric examination: For the fetus whose mother is blood type O and father-to-be is blood type A, B and AB, ABO hemolytic disease during pregnancy may occur because the serum of blood type O contains A and B antibodies, which will cause hemolysis when it enters into the body of the fetus. At this time, regular obstetric examination is needed, and after the birth of the newborn, it is necessary to promptly determine the blood type of the newborn and the concentration of antibodies in the body, jaundice, so that timely treatment can be carried out to avoid serious consequences.
