Randomized Controlled TrialReduction of conscious sedation requirements by olfactory stimulation: a prospective randomized single-blinded trial.
This study investigated the possibility that olfactory stimulation would decrease sedation needed for colonoscopy and therefore decrease the recovery time needed after conscious sedation. ⋯ Overall, there is no difference between olfactory stimulation and inhaled oxygen with regard to amount of sedation used and recovery times for colonoscopy. An inhaled cherry- scent may not have as great a calming effect as other scents that have been studied.
