S100B levels. A, S100B levels (mean ± standard error) were measured preoperatively (Baseline), at the time of cross-clamping (PreClamp), and 24, 48, and 72 hours postoperatively for the injured and uninjured patient groups. There was no significant difference in baseline S100B values for the groups; however, there were significant differences at each of the remaining time points (*P < 0.05). B, when changes from baseline values were calculated, patients with cognitive dysfunction exhibited significantly greater increases in S100B levels than did patients without cognitive dysfunction at 24 (*P < 0.05), 48 (***P < 0.001), and 72 (**P < 0.01) hours after surgery.
