A Psychomotor Recuperation Study After Deep Sedation for Colonoscopy Between Target Controlled and Manual Titration of Propofol

One group will be sedated with a manual titration technique: here the titration of propofol is done manually by the anesthetist. Dosages may range between 50 and 400mg, given by boluses of 20-50mg.

The other group will be sedated with a target controlled infusion technique (pump, marsh or Schneider). The anesthetist can titrate indirectly by adjusting the target controlled infusion to achieve adequate sedation. The concentrations of propofol may vary between 2 and 6 µg/ml, achieved by increments of 0.5-1.5 µg/ml.
