Common Types Of Adult Nasogastric Tubes (NGTs)

Pinterest LinkedIn Tumblr

As an anesthesiologist, I’ve placed nasogastric/orogastric tubes (NGTs/OGTs) in patients who will remain intubated post-operatively to decompress the stomach and to provide a short-term enteral route of administration while the patient remains on mechanical ventilation. As an intensivist, I more commonly place NGTs to deliver nutrition (ie, tube feeds) and medications in patients with impaired swallowing (a complex mechanism!)

The Salem-Sump is a relatively large bore (10 – 18 French) dual lumen tube which permits suctioning of gastric contents as well as medication/nutrition delivery. One port allows for wall-suction drainage or administration of therapy (often facilitated with a Lopez valve), while the other port is the sump vent which equalizes gastric and atmospheric pressure (do NOT apply suction to this).

In comparison, traditional small bore feeding tubes (SBFT, ie Corpak) and Dobhoff tubes (named for the two physicians who created it – Drs. DOBbie and HOFFmeister) are smaller and more flexible permitting a greater degree of comfort for the patient. These tubes contain an inner stylet which facilitates placement and is removed prior to usage. Due to the much more pliable material and smaller lumens, these tubes aren’t designed for suctioning and should only be used for administration of tube feeds/medications.
