Jan,
I too am in awe that your nurses are not up to speed on the gravity bags. If your husband is on medicare, the bags and ensure are paid for through home health. The doctor needs to write a script for it. I imagine insurance would cover it too. Any city of moderate size should have a home health pharmacy that could fill it. Also make sure that the Peg is not being moved into the intestine when your husband enperiences the sucking in of the tube. You may have to insist on a dye study to see where it is and how it functions. John had to have one and that Peg had to be removed and replaced. A properly working Peg is a God send. It keeps the person totally nurished. As with Brian, John could have never done syring feeding. It would have been too much too fast. It takes him around 45 minutes to do two cans of ensure.
Remember the rule You know your own body. Don't let anyone blow you off. If you have questions-- make sure that they are answered to your satisfaction.
Good Luck.
Meredith
