Wounds

I have been following a patient recently and the doctors suddenly took him off TF and put him on TPN and we could not figure out why they were doing this. There is no mention of gastric residuals and his labs seemed fine so all in all he seemed to be tolerating it well. We had known he has an open surgical wound on his stomach but they didn't really discuss it much in the notes. Well I got my answer today. PT went in to change his wound sponge and this was the largest gaping hole I have ever seen. It was probably 8-10 in in length and 5-6 inches in width. On the inside it wasnt actually the wound bed but some sort of gauze or netting to protect his organs. They then shoved a huge black sponge into the open wound, covered it with tape and vacuumed it to seal everything. All the while they are doing this on a man who keeps swinging his arm around and trying to swat them away but his hand keeps going in the wound. So i got in there and held his arm while they finished. Definitely not for the faint of heart!
Hope everyone is doing well.
