![]() ![]() ![]() When working with people who have nasogastric tubes, remember the following care measures: The main lumen is attached to suction, the second lumen acts as an air vent which prevents suctioning of gastric mucosa when the stomach is empty. Sometimes referred to as a Salem Sump or Levin, these tubes are double lumen. ![]() NG tubes for these purposes generally have a larger lumen than tubes used for feeding purposes (Perry et al., 2018). In the event a patient swallows toxic substances, a nasogastric tube can be inserted and used to lavage or wash the stomach of its contents. In these situations, the NG tube is used to relieve gastric distention and in doing so prevent nausea and vomiting. Removal of gastric contents can be done either by gravity or by being connected to a suction pump. In these situations a naso gastric tube is used for gastric decompression. Sometimes normal peristalsis is interrupted (i.e., post op, in association with certain conditions). Placement of blindly inserted enteral tubes must be verified by x-ray before initial use for feedings or medication administration (Bourgault et al., 2014). Blindly inserted means there has not been direct visualization that the tube in the correct position. NG feeding tubes are used for patients who may have swallowing difficulties or require additional nutritional supplements. NG tubes are used for feeding, gastric decompression, or gastric lavage.Īn NG tube used for feeding is usually softer and has a smaller lumen than tubes used for gastric suctioning / decompression. 10.3 Nasogastric Tubes Using a Nasogastric TubeĪ nasogastric (NG) tube is a hollow flexible plastic or silicone tube inserted through a nare, past the nasopharynx, oropharynx and into the stomach or the upper portion of the small intestine (the later referred to as naso-jejunum). ![]()
