My ileus first surgery was awful (I have a HUGE scar 'cause things were done open (not laparoscopically) in 1991; my bloated stomach on that scar was terrible. You probably shouldn't have pulled out your NG. I had to have mine in about 4 days before things started moving well enough to deal without it.
We usually do "trickle feeds" in the ICU, meaning 10mls an hour, to help stimulate the gut prior to an ileus (hoping they don't get one), but you don't want to put a ton of food in a belly IN an ileus. You'll just puke.
