Trick of the Trade: Clearing the Clogged Feeding Tube
3March 4, 2013 by EmerJencyWEBB
Obstructed feeding tubes are a common complaint in the ED. In the past, I tackled this problem with an attempt at flushing with a 60 cc slip tip syringe which usually left everybody in the room wet after the pressure eventually exceeded the connection to the feeding tube. There’s also the Coca-Cola trick, and a few medical grade solutions designed to dissolve tube feed obstructions.
Sometimes these things worked. A lot of times they didn’t and we ended up either replacing the tube in the ED or putting in a temporary NG or transpyloric tube until they could be seen by their surgeon.
Last night I was confronted with a similar problem and my nurse Robert showed me his easy trick to clear the clogged tube (that anecdotally for him has had a high percentage success rate). This is how he does it, and how we did it last night…
Step One: Attach a tapered luer-lock foley catheter adapter to a 3 cc syringe.
Step Two: Hook this apparatus up to the end of the feeding tube.
Step Three: Push hard and steady and usually, all of a sudden the obstruction will clear and flushing the tube will be a dream once again.
For some reason, the smaller syringe and the tapered adapter creates a lot more force with a lot less effort on your part. Plus, the apparatus will likely not explode and rain down tons of sterile water on you and your patient.
Thanks Robert!
The smaller syringe concept has to do with Pascal’s principle, as counterintuitive as it is. Great post!

Thanks for your comment!
Be aware you do not ‘blow up’ or rupture your tube. Pressure goes up significantly exceeding the allowable limits (on connection points or weak areas like contrast lines). If you find a better solution, make sure to let me know.
