After the blood is retrieved, if the patient cannot go out for blood transfusion, what should be done with the blood?

Hello, after blood products are taken out from the blood transfusion department, they must be stored at low temperature or normal temperature according to regulations. They cannot be used after the storage time. Blood products must be returned to the blood transfusion department for uniform destruction in accordance with regulations. In addition, patients are not allowed to leave the ward at will. Medical staff are responsible for informing patients that they cannot go out. If the patient goes out and blood products cannot be transfused in time, both doctors and patients are responsible if financial losses are caused.
