I am reading and reading on NG tubes trying to make sure I understand how they work and what they are used for. I find that if I don't truly understand the why of things I won't be able to learn the steps for the skills. What is... Read More

    Why on earth would they have a Salem (vented) sump tube for feedings? If they're too lazy to change to a single-lumen tube, all they can do is block off the air vent tube, because, as Esme notes, stomach contents (in this case, the Ensure or whatever) will migrate right up it and make a helluva mess in the bed.

    Thank you! This is all making sooo much more sense to me. That was kind of my thought on this too. This is all for lab simulation so they've been having us use the salem sump for everything. This is why I have been so confused and nothing has made sense. So in real life practice, if someone was going to be ready for a feeding you would most likely just remove the salem sump and put in a single lumen tube. School is so frustrating. I do think I understand all the differences between the tubes now and I was trying to prep for my upcoming labs. I cannot thank you and Esme enough for all the help you have given on understanding this. (I'm still a first term nursing student so I appreciate you all bearing with me.)

    What we do for fun

    Glad to help. We remember (oh, god, so clearly...) what it was like to be young, inexperienced, and clueless. Later on when you have more experience and understanding, remember how it felt and you'll be able to explain better too.

    One thing to add-please be sure you know if meds can be placed into the tube. Many cannot, so you will need to alert MD if another route or another medication is required. Also, some meds are absorbed in the stomach, so they need to be administered via tubes that terminate in the stomach. A Dobb-Hoff (weighted tube) terminates in the duodenum, past the stomach. A majority of digitalis is aborbed in the stomach, so if the patient has a Dobb-Hoff they will not receive therapeutic levels of dig.

    So glad you are questioning this now!!

    Right-- so any tube that goes into the GI tract below the stomach-- Dobhoff, J-tube, etc.-- you need to remember this and be sure your physician orders are appropriate. Believe it or not, a lot of them don't remember that part when they say to continue oral meds via tube.

    Thank you all... so many little details are left out in formal education! So I have another question about an NG tube... the thinner tube (used for feeding & meds with the ko pump which I believe they called a "cortrak" at my last job - brand name). I had a patient with the NG tube who was NPO, it was only used for administering PO meds & was never connected to the pump. Does it matter which port I use to administer the meds knowing that it was never used for feeding/never hooked up to pump (no formula had ever been out into the lumen)

    I ask because gravity alone didn't do a whole lot, my preceptor showed me using a bulb syringe going through the main port typically for feeding. And I was wondering if there would be less resistance using the port designated for PO meds. In my last job, my experience was always with someone that had continuous feeding and I seem to recall the meds going down easier.

    Never put anything down the pigtail except air, that is "vent" if it does need to go to suction.

    Not talking about sump... The thin yellow tube for feeding & PO Meds used with the KO pump has two ports at the end.

    Best practice so it becomes habit would be use the port designated for meds 😃
