I have a girl in a school setting, age 3 years, who has a pediatric G-J tube. There are no doctor's orders for flush. Mother states that she only flushes gastric port, after her medications. Isn't J-tubes supposed to be flushed, with warm sterile water, every 4 hours for continuous feed and after each bolus feed? If so, what are the usual guidelines. Of course, I am asking mother for doctor's orders, but just want to know.
