A Psychomotor Recuperation Study After Deep Sedation for Colonoscopy Between Target Controlled and Manual Titration of Propofol.
In Brief
A Phase 4 clinical trial evaluating Manual titration of propofol and Target controlled infusion of propofol for Colonoscopy (Ambulatory Patients). Completed, enrolled 164 participants across 1 site.
Detailed Summary
Deep sedation with propofol for ambulatory colonoscopy has become standard clinical practice.To achieve the necessary (e.g.: no excessive movement and no awareness) level of sedation during colonoscopy, propofol can be titrated by hand, continuous infusion or by target controlled infusion. The aim of the investigators is to evaluate sedation efficacy and recovery between two groups of ambulatory patients having a colonoscopy: one group will receive a manual titration of propofol, the other group a target controlled infusion (TCI) of propofol. The investigators will evaluate both groups before, during and after colonoscopy for adverse events, quality of sedation and recovery. When patients are estimated to be ready for discharge, they will also be subjected to a cognitive and a psychomotoricity test.

Timeline
Interventions
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.
