An Anesthetic Experience of a Patient with Cis A2B3 Blood Type.

Cis A2B3 is a rare blood type with unusual inheritance pattern of A2, B3 genes on the same chromosome in contradiction to the general Mendelian pattern. Unlike the AB blood type, cis A2B3 shows weaker B antigenicity and unexpectedly has moderate amount of anti-B antibody in serum. Thus it has the potential of misidentification as blood type A or AB and the possibility of acute major transfusion reaction from transfusion of the usually known AB blood group RBCs. This is a case report of anesthetic management of one patient with his blood type discovered as cis A2B3 preoperatively. During hip surgery he received 2 units of washed O RBCs without any problems. I report the anesthetic experience with a brief review of literature.
Key Words: Anesthesia: blood transfusion; preoperative evaluation; Blood: transfusion; cis A2B3
