I "received" the PEG while in the hospital for mandibulectomy and ND. I am not sure at what stage of hospitalization but it was sometime after surgery. I was due to have a swallow test and possibly have it removed about a month after surgery. That would have been the first week of August. However, we live in New Orleans and that is the week that the infamous Madam Katrina decided to pay a visit to our area.
Not all my meds were available in liquid form. It would be advisable to be prepared ahead of time for this possibility. Tell your Mom to check his meds. If any will need to be crushed she should buy a pill crusher/splitter combo and test the meds. The 1st one I got did not do too well so I got another. Also, ask nutritionist in the hospital what if any vitamins he should be on. Don't take "a good multi-vitamin" as an answer. I recently discovered that the one I had been taking for years had much more of some ingredients than I needed. Your pharmacist should be able to help with this as well.

Another suggestion from a practical side is to put an old towel on his lap when he pours stuff into the tube.

Let him know that he is not going through this alone. If it is possible get a laptop to him so he can communicate with others on the forum himself. It must be terribly frustrating for him to be so dependant on others.
