Intravenous Saline Pre-hydration in Patients Undergoing Outpatient Colonoscopy

Summary

Colonoscopy and sedation are frequently accompanied by hypotension, which reduces the amount of sedation able to be employed. Blood pressure is restored by the infusion of intravenous normal saline. Prophylactic infusion of normal saline may enhance the colonoscopy completion rate, and patient comfort during colonoscopy and during the recovery from colonoscopy. The investigators propose randomising consenting adult patients attending outpatient colonoscopy to one of two treatment arms: (i) A control arm (ii) A treatment arm, with pre-hydration with an infusion of 1.0 litre of normal saline immediately prior to colonoscopy. Outcome measures include colonoscopy completion rates, hypotension during or after colonoscopy, and patient ratings of comfort and satisfaction.
