In this case just pull the line 1 cm.
It's worse when you insert the UV line shortly after birth, and when the baby develops distension after a day or two, the tip will be pulled to the level below diaphragm. It happened to me several times. For that reason I try to place the tip rather at T8 then T9.
If the tip gets pulled to the level below diaphragm on the AP XR, you may still be able to salvage the line by getting a cross table lateral XR which will show more precisely the position of the tip in relation to the posterior diaphragm, and if you are lucky it may be still positioned above it.

We use gastral tubes with 5ml/KG NaCl0,9% rectally in the second day of life if a premie (《1500g) to stimulate mekonium release (because changings of enteral feeding regimes depending on mek rel). With this procedere we stimulate bowelmovment. It works most everytime. We don't wait for problems. I believe most Effect depends to the distending fluid
As long as premies stay in incubator temp is measured with rectal probe. Later with Thermometer (without plastic wrap). We do no Stimulation.
For Colic gas seldom we use small airwaytube 3 cm inserted for 30 min.
