Anesthesia for coronary artery bypass grafting with hypothermic cardiopulmonary bypass in a patient with a A2B negative Blood Group

abstract: 2B negative is one of rare subgroups of ABO blood group system. Herein, we report a 59-year-old male patient who was candidate for coronary artery bypass grafting surgery (CABG) due to coronary artery stenosis. The patient`s blood group was reported as AB negative in routine laboratory, and because of doubtful result, a complementary test confirmed his blood group as A2B negative. The consultant hematologist recommended reserving either negative A2B packed red blood cell (PRBC) or if unavailable O- blood group. After induction of anesthesia three units of patient’s own blood were collected and replaced by colloid solution. The patient underwent CABG with hypothermic cardiopulmonar.
