I always thought they were kept NPO so they would be hungry. They want the baby to eat so they can look at the transit of feeding. Our radiologist typically want the infants to be NPO for 4 hours. I usually lie about the time of the last feed and let them go up after 1-2 hours. If they are vomitting up each feed, then they are always hungry.

> Hello All,
> I am curious to know if other institutions have NPO requirements in order to do an ultrasound for pyloric stenosis? I recently started a job at a new hospital and was told that we have to keep babies NPO for 3 hours before radiology will do the ultrasound, which was something I had never heard before. Not only does this delay time to diagnosis, but also distresses families with young babies who scream for that last hour before they can have the test done. I looked up the literature and it seems like this used to be the standard, but based on the measurements that need to be obtained it seems somewhat unnecessary.

> - Do your institutions have a policy about keeping babies NPO prior to US for pyloric stenosis, or will they do it at any point in time?
> - If they require NPO, for how long?
> - Does anyone have literature that substantiates this practice, or more importantly, literature that states this practice is unnecessary?
