I don't know if this is a recent post and still an issue for people or its been resolved. Several things we did made a difference while Mom was on PD. That included: 1) making sure Mom was positioned in bed to ensure she was not crunched up, and, hips higher than belly. Did this by elevating the foot of the BED 12 inches, as Mom was non compliant with elevating her legs. 2.) Pay attention to whether constipation was an issue as it's tough to expet to drain properly if the catheter is being pinched by backed up stool. 3) rotate onto left and right side with the "top" arm out like you going to grab onto the safety pole and pay attention to which side drains better. That's the side to want to be on to aid draining if you are having trouble draining while lying flat. By the way, having the bed elevated and correcting the physical way Mom was stretched out, eliminated those leg cramps she used to get EVERY night, when her position was crumpled uo.
