O negative blood can be used when there is not sufficient time for crossmatch.     Case   A 68-year-old woman was transferred to the hospital cause of trauma. Due to her hemorrhage and paleness, intravenous isotonic fluids followed by 1 unit of O negative, 2 units of B positive, and 2 units of AB positive packed RBCs were administered. Her blood group was determined to be AB positive. She had neither any hemolytic symptoms nor any other problems and was discharged from the hospital.     Conclusions   In emergencies when there is not enough time for crossmatching and antibody screening, O negative blood can be administered.   Key words : Blood transfusion, Trauma, Cross match, Guideline SP - 273 EP - 276 AU - Dahi M, AU - Dabbagh A, AD - KW - Array KW - Blood transfusion KW - Trauma KW - Cross match KW - Guideline UR - http://bloodjournal.ir/article-1-108-en.html ER -
