Does propofol mode of administration influence psychomotor recovery time after sedation for colonoscopy: A prospective randomized assessor-blinded trial.

Background: Propofol sedation has become increasingly popular for colonoscopy. Different modes of propofol administration have been described, but their influence on psychomotor recovery time remains largely unknown. This prospective randomized assessor-blinded study tested the hypothesis that target-controlled infusion system (TCI) combined with sedation depth monitoring should be associated with a more stable sedation than intermittent bolus application with clinical monitoring of sedation depth, resulting in a faster psychomotor skills recovery.
