PURPOSE: The purpose of this study was to compare the incidence of hypotension during sedation in adults presenting for elective colonoscopy and randomized to intravenous Plasma-Lyte 148(®) at either 2 mL·kg(-1) (low volume) or 20 mL·kg(-1) (high volume). METHODS: Patients aged ≥ 18 yr presenting for elective colonoscopy, with or without gastroscopy, after oral bowel preparation were randomized to receive the intervention immediately before the start of the procedure. Hypotension was defined as a ≥ 25% decrease in systolic blood pressure (SBP) from baseline during the procedure. Secondary outcomes included SBP < 90 mmHg, lowest SBP during sedation, duration of hypotension, use of vasopressor..View full abstract
