Dear Smlahlum, [do you have a nickname?] At his age, your Dad's body has been through a battle akin to being in WW2! And your Mom likely feels like she is a battle nurse! Hopefully, you all will be able to give them both much needed support. You said you Dad had a feeding tube. Tell your Mom to go to a good grocery store or Walmart,etc. and bring in a couple of bottles of Pedialyte[liquid- for children-] Use it along with or as a replacement for water through his peg tube. It will help with the dehydration and maybe some of his confusion. What kind of pain meds. is he on? Could they be causing confusion also? Keep in mind that he may not be "giving up", he just may be exhausted from all of this and needs lots of rest. [you Mom does too] Keep him comfortable, hydrated, and try to eliminate as much aggrevation as possible in his daily life. Give him time to recover from this. Amy in the Oz
