Figure 1. Blood sevoflurane concentration (mean plus/minus SE) in control (n = 10, open circles) and disulfiram-treated (n = 11, closed circles) patients. Sevoflurane was administered from 0 to 3 h, unless the surgical procedure ended before 3 h. Anesthetic concentrations in the two groups were not significantly different at any time. Areas under the curves were 2,790 plus/minus 130 and 2,580 plus/minus 280 micro Meter *symbol* h, respectively, in control and disulfiram-treated patients (P > 0.05).
