[Arousal in various analgosedation schedules].

The patterns of recovery of patients who received seven different analgesic and sedative treatments were investigated with regard to the time at which the subjects awoke. For observations of the neurologic status, we developed a special score. The analgesic and sedative therapies were given at three various doses. The combination of fentanyl/midazolam, alfentanil/midazolam and ketamine/flunitrazepam showed the best results. Piritramid/promethazine, pethidine/flunitrazepam, pethidine/promethazine and tramadol/methohexital required more time for awakening. On the basis of these results, we prefer to use the combination of fentanyl/midazolam, alfentanil/midazolam and ketamine/flunitrazepam to judge all patients' neurologic scores.
