Just to point out a possible problem that can occur if the NG is left in too long.
In Ireland, my brother had a temporary ileostomy because of a colonoscopy gone wrong. His colon was punctured by the scope, he had diverticulitis, and really shouldn't have had the scope at that time.
Anyway... after surgery, an NG tube was placed. It took maybe two weeks for his colon to behave normally and the NG came out.
He began having light stuff, like soup, crackers, etc., and seemed okay. I was my brother's "wingman" because I know shit goes wrong and someone with a bit of medical info and knowledge has to be watching out for problems.
My brother was losing weight instead of gaining weight over the next week. The nurses said that he had regular meals (Irish Hospital food is quite good actually!!) but he didn't seem to be improving in his mobility and his weight, which was really worrying. At the best, he would weigh... 125 or 30 pounds, so when I could count his ribs, I knew something was wrong.
I started bringing him Burger King and McDonald's food and thick milkshakes... he likes it so I figured I would load him up with calories. All this time he had an IV for fluids. I brought him cases of "Ensure" in all flavors and left them within arm's reach.
I was going to see him every single day and nobody could figure it out, he seemed to be eating and drinking but was still losing weight and cancer was ruled out... we were all scratching our heads!!!
One day another brother joined me for my daily visit to the hospital. We brought Big Macs for the three of us with fries and milkshakes. I wanted to sit and watch him eating and sure enough... bites were taken and fries were eaten and we became even more worried and puzzled.
As we said our goodbyes... eat your food lecture... etc... and left. As we entered the hall where the patient couldn't see us, my brother peeked around the corner and had a big grin when he turned to me. "Take a look, he's spitting the food that he had in his mouth into a paper napkin and stuffing it into the pocket of his robe"!!! Now we were really puzzled.
We speculated for a few minutes and went back to his bedside. I asked if he liked the Ensure and he said he loved it and showed me that half of the twelve-pack I had brought was gone!! I had a bright idea and opened his locker to get new socks for him.
Mystery solved... part of the mystery. There must have been at least 12 bottles of Ensure hidden under his clothes... obviously hidden on purpose!!! Then I looked in the bin and there were several napkins containing chewed food!!! The mystery deepens!!!
We spent an hour talking and asking him why he was doing all this and pretending to eat but actually eating almost nothing. He could not explain it himself!! The nurses would often bring the food and leave it on his table. The kitchen staff would take the tray of uneaten food away and when the nurse looked in again she assumed he had eaten it and added the food intake to his chart!!
I asked several nurses if they had actually seen my brother eat any of the food that he was given. Their memory had convinced them that he had eaten, the food was there, the food was gone. After thinking for a minute, one nurse admitted that she hadn't actually seen him eat. I first asked my brother if anyone had looked down his throat to check for anything that would inhibit his ingestion of food. He said yes that someone had done an inspection of his mouth and throat and it was all good in there. I persevered and asked if they had used an instrument to look down there to get a look way in there. He said he just opened his mouth, they had a quick peek and said his throat was fine. I called his doc for a meeting and in the hallway. I told him the story (food-filled napkins, the hidden Ensure) and asked for an ENT to do a proper examination of his throat... right down to his vocal cords. No problem he said, we'll get our ENT in here to see your brother today.
The lady who came to see him was actually a speech therapist. I was a bit puzzled but I waited and observed what was going on.
In about 5 minutes, that speech therapist had the mystery solved!! The NG tube had been left in his throat for longer than usual, his belly just would not wake up!! When it's in for a long time it can paralyze a part of the throat called the pharynx. There is a little flap of muscle that closes off the path to your lungs when you swallow food to prevent aspiration and that was the problem.
My brother's body kicked the food back when he tried to swallow. I guess he was being the good patient and do what he had to do... eat food!! He didn't know why exactly he wasn't swallowing the food and in his severely weakened condition he could make no sense of it all.
I forget how they resolved the flap problem. I believe they gave him IV nutrition and fluids until the "flap" began operating again by itself. When it got back to normal he was eating like a horse!!!
This is a quite rare condition and only occurs after weeks of having an NG tube so don't let it color your opinion of NGs too much. It is a pain swallowing that thing while gulping water but sometimes it's just gotta be done!!
