A child with a NG tube set to low continuous suction has an IV of D5 1/4NS with 20meq KCl/L infusing @ 25ml/hr. The NG drainage is to be measured every 4 hours and the amount of drainage replaced with a second IV of 1/2 NS. The maximum hourly rate for this child is 35ml/hr. The child has 30 ml NG drainage. What is the infusion time of the replacement IV fluid?

It is common to replace NG output with IV fluids in children. Usually the NG output is totaled every 4-8hours, and then replaced over the next 4-8 hours with the same amount of fluid, given IV.

This child had 30cc of NG output in 4 hours. 30cc/4hr = 7.5 cc/hour of replacement fluid to be given for the next 4 hours.

The child's maintenance IV is running at 25 cc/hr, and you will be administering an additional 7.5cc/hr for the next 4 hours. That comes to a total of 32.5cc/hr for the 4 hour period, which does not exceed the child's maximum IV rate.
