Abstract Background: In patients with cyanotic congenital heart disease (CHD), cerebral oxygenation may be maintained by elevations in hematocrit (Hct). Hemodilution accompanying cardiopulmonary bypass (CPB), however, can disrupt cerebral oxygen balance, leading to fluctuations in cerebral oxygen saturation (ScO2). The present study investigated the effects of Hct changes on the fluctuation of ScO2 during CPB in cyanotic CHD using performance measurement (PM). Methods: Children with CHD (51 acyanotic and 46 cyanotic) who had undergone cardiac surgery using CPB were enrolled. Median performance error (MDPE), median absolute performance error (MDAPE), and wobble parameters of ScO2 were calculated before (reference value), during, and… More >
