At loss of consciousness (LOC), mean Ce was 1.37 ± 0.22 mcg / ml, the mean LOC time was 82 ± 22 sec and the mean dose of propofol was 80.1 ± 14.31 mg, the mean Ce on wakening was 1.34 ± 0.24 mcg / ml and the mean time was 14.6 ± 3.11 min. Conclusion: smooth propofol TCI induction, good hemodynamic stability, prediction of wakening was exactly.
