Abstract
OBJECTIVES: To compare ankle and brachial blood pressure monitoring before and during colonoscopy using automated noninvasive blood pressure (NIBP) monitors. METHODS: Forty-five consecutive patients who presented for outpatient colonoscopy had both ankle and brachial blood pressure monitoring with automated NIBP using an appropriately sized cuff for arm or leg size. Three baseline measurements were obtained, and then measurements were taken at 5-minute intervals during conscious sedation, with brachial blood pressure being the standard. RESULTS: The average of all of the ankle blood pressures was significantly higher for all systolic and mean arterial blood pressure readings. Diastolic blood pressure readings were higher at baseline, but not significantly different during the procedure. CONCLUSIONS: Ankle systolic and mean arterial blood pressures using automated NIBP monitoring for conscious sedation are significantly higher than brachial blood pressures. Ankle NIBP monitoring should only be used if brachial NIBP monitoring is not feasible, taking into consideration that ankle NIBP pressures are generally higher than brachial.
