Abstract

The standard voiding position for individuals using a bedpan or urinal involves elevation of the head by 60 degrees from the bed because this reduces the intra-abdominal pressure and is considered comfortable. Nursing technical literatures mention a range of head-elevation angles but do not specify the optimum angle. This study focused on the relation between intra-abdominal pressure and various head-elevation angles when using a bedpan. We evaluated 14 healthy young women (average body mass index, 21±3.08) aged between 18 and 22 years. Surface electromyography was used to measure max abdominal pressure at 3-s intervals during normal respiratory movement with a range of head elevation angles (at 75, 60, 45, 30, 15 and 0 degrees). No significant difference was observed between intra-abdominal pressure and elevation angles.
