Good for you, Bill!
I've heard a lot about the apple juice ploy, but that would probably cause a freaky sugar/fructose reading, and might keep you incarcerated longer. Tap water is a good number two ploy, or should we say number one?
It's amazing how many hospital rules are so self-perpetuating, they don't even have to yield to common sense anymore. Nurses should be acutely aware of the signs of even mild dehydration.
Gina makes a good point about the K factor (potassium). All of your minerals/electrolytes can be affected. Of course, you don't want too much potassium, either. A splash of potassium salts is frequently used to stop the heart for OHS.
Some thoughts to check with your professionals:
- I wonder whether you need to take in some fluids in to "prime the pump," as it were. You did say you were on strict fluid restriction immediately, as I recall.
- You likely have your feet up much of the time. That's fine, but you realize that all of the fluids other than blood are moved through your body by the lymphatic system. This works through muscle contractions, centrifugal force, and gravity. While your feet are up, consider stretching and contracting your leg and foot muscles to help move that edema along. A gentle massage going from the foot toward the knee might also help.
Maybe one of your medical professionals can lend some brain cells to more deeply consider your issue before it becomes more of a big deal, requiring intervention, some of which will likely be unnecessary. A Foley is of no value, if the bladder is empty.
And of course, it's the weekend. That's always when the complicated misadventures transpire - when none of the "regulars" are on duty.
Ross, I can't believe this, but you may have generated the largest number of people to ever attempt to simultaneously "will" someone else to pee. There has to be a Guiness record in this somewhere.
