Nasogastric Tube Placement in the Bariatric Patient
The nasogastric tubes (NGTs) are a commonly used instrument in the field of surgery. Most NGTs are single- or double-lumen tubes made of flexible plastic which are inserted through the nasal passageways down the throat and into the stomach. Measured markings and standardized techniques allow for the blind insertion of NGTs on a routine basis by physicians and nurses. NGTs are used to decompress the stomach, remove gastric contents in the case of a blockage, and also administer medications or feeding in patients unable to swallow on their own.
