Staged Arterial Switch Operation without Homologous Blood Transfusion / 日本心臓血管外科学会雑誌

Staged arterial switch operation without homologous blood transfusion was successfully performed in 5 patients weighing 4.1-11.0kg (double outlet right ventricle: 2 cases, transposition of great arteries: 3 cases). The postoperative hemodynamics and respiratory status were uneventful in all patients (initial central venous pressure after ICU admission: 9.0-14.5cmH₂O, mean 12.5cmH₂O, duration of intubation: 3.5-18.0h, mean 7.8h). Autologous blood donation immediately after induction of anesthesia and minimization of bypass circuit were effective methods for open heart surgery without homologous blood transfusion, particularly in staged arterial switch operation requiring prolonged cardiopulmonary bypass.
