| Research Abstract |
In study I for young and middle aged patients with a new management method for sedation with propofol predicting the optimal blood concentration during surgery within a small error range during induction, it was revealed that optimal initial dose of target blood concentration was 2.2μg/ml. That is, a maximum discrepancy between calculated brain concentration at the sedation level aimed for during induction and calculated blood concentration during surgery was the least when initial target blood concentration had been set at 2.2μg/ml. In study II for elderly patients with the same management method for sedation with propofol, it was not revealed which initial blood concentration is optimal. The differences of the results between the two studies were not clear, however, it may due to the large individual variance of the pharmacodynamic and/or pharmacokinetic effect in the elderly.
