[Open heart surgery without blood transfusion for complete atrioventricular septal defect associated with tetralogy of Fallot].

Open heart surgery without blood transfusion was successfully performed in two patients with complete atrioventricular septal defect associated with tetralogy of Fallot. The postoperative hemodynamics and respiratory status were uneventful in both patients (central venous pressure after ICU admission: 13.7 cmH2O and 11.5 cmH2O, intubation time after surgery: 9 hours and 11 hours). Autologous blood donation immediately after induction of anesthesia and minimization of bypass circuit were effective methods for open heart surgery without blood transfusion, particularly in cyanotic patients requiring prolonged cardiopulmonary bypass for intracardiac repair.
