Hello Winicki,
I'm not sure as to exactly what you would like to know, so I'll explain what I did when I was sent home after my surgery. I had 1/3 of the base of my tongue removed, a tracheotomy plus the PEG tube.
When I got home, I had a rack that had a bag which feed a can of Nutrin 1.5 into my PEG tube, which in turn took roughly 1 and a half hours to feed into my stomach. I needed roughly 8 cans a day which I figured would mean I would be sitting in a chair for 12 hours. Not going to happen in my opinion. I was given 2 syringes to flush the PEG tube after using the cans or to hydrate myself with water.
What I did was, use the gravity method of feeding myself with the syringe. I put the syringe ( with the plunger removed ) into the PEG tube and elevated it enough to be above the tube and would pour the Nutrin slowly into the syringe, . I paced it so the I could do one can every 10 minutes. 2 per feeding was good for me. Then I could go about other things. If he goes too fast, it might upset his stomach. I made sure everything that went into my stomach was at room temperature.
As far as making sure the PEG tube stayed in place when it wasn't in use, I taped it to my chest. I shaved a good area around the PEG tube so that I wouldn't be pulling hair out each time I needed to use it. Keep the area around the PEG clean, clean at least twice a day. The cap on the end popped open once after a feeding and I lost some Nutrin. So after that, I would bend the tube at the end and wrap a rubber band around it so that even if the cap popped open again, it was kinked and I wouldn't leak out. The Doctor liked that idea.
I hope this is of some help, if not, please ask what you want to know, there are allot of knowledgeable people here to help with questions, they have been down this road already.
My Best to everyone here
