Abstract

Maintaining the balance between oxygen supply and demand during a cardiopulmonary bypass (CPB) is a key issue in the anesthetic management of cardiovascular surgery. Although many reports have described this balance at a constant, low body temperature, little is known about the balance during the cooling and the rewarming phase of CPB. Nakajima et al. [1] reported that jugular venous hemoglobin saturation (SjO2) decreased during the rewarming phase of CPB, and that rapid rewarming produced a pronounced decrease in SjO2. We analyzed retrospectively the intraoperative changes in SjO2, mixed venous oxygen saturation (SV̄O2), and oxygen consumption (V̇O2) in three patients who underwent reconstruction of the thoracic aorta, two of whom developed postoperative neurological deficits.
