Minimally Sedated Patient Undergoing Colonoscopy
Conditions
Keywords
cecal intubation time, water exchange, pain
Brief summary
This prospective, randomize, controlled trial will compared maximal to half-maximal suction pressure applied during water exchange in patients undergoing minimally sedated colonoscopy. We test the hypothesis that maximal suction pressure is more efficient and causes shorter insertion time.
Interventions
PROCEDUREhalf-maximal pressure
the pressure level of the suction unit (DF 601, Hanlien, Taipei, Taiwan) will be set at the half-maximal (-35 cm Hg).
PROCEDUREmaximal pressure
The pressure level of the suction unit (DF 601, Hanlien, Taipei, Taiwan) will be set at the maximal (-70 cm Hg).
