Conditions
Brief summary
This study is important in defining the baseline physiological state of patients presenting for outpatient endoscopy. It has been observed that intravenous fluids do not prevent hypotension in patients who are undergoing endoscopy. One possible explanation for this is that patients are not intravascularly deplete after bowel preparation solution. This study will determine what the rate of intravascular depletion in patients undergoing endoscopy after bowel preparation solution is.
Interventions
In patients who have taken bowel preparation solution for an endoscopy examination (colonoscopy +/- gastroscopy) their intravascular fluid status will be assessed using echocardiography views before and after passive leg raise testing. The volume assessment will take approximately 20minutes and occur immediately prior to the endoscopy procedure start. This aims to determine if patients are intravascularly deplete prior to endoscopy examination.
All assessments will be completed on the day of
