What is nasogastric (NG) tube?
A nasogastric (NG) tube is a flexible tube of rubber or plastic that is passed through the nose, down through the esophagus, and into the stomach. The tube is placed into your digestive system in order to deliver or remove substances to and from the stomach.
How long does a nasogastric tube stay in after surgery?
On average, the nasogastric tube was maintained for 3.2 +/- 2.1 days (range 1-8) after surgery. The average daily nasogastric output was 440 +/- 283 mL (range 68-1565). What color is gastric secretions? In their normal state, gastric juices are usually clear in color. HCl is an important component in gastric juice.
What are the signs and symptoms of nasogastric tube removal?
These include flatus, bowel movements, decrease in nasogastric tube output amount, change of nasogastric tube output color from bilious (green) to more gastric (yellow) or salivary (clear/foamy) quality. Some physicians prefer to perform a clamp trial before removal of the nasogastric tube.
What is the role of an RN in nasogastric tube placement?
It is within an RN’s scope of practice to place, monitor and maintain a nasogastric tube, although most facilities require a physician order to initiate or discontinue an NG tube, or to change the type of feeding administered via an NG tube.

How much should an NG tube drain?
Once the NG tube output is less than 500 mL over a 24 hour period with at least two other signs of return of bowel function the NG tube will be removed. Other signs of bowel function include flatus, bowel movement, change of NG tube output from bilious to more clear/frothy character, and hunger.

What is the standard nasogastric tube used for?
For decompression, the standard tube used is a double-lumen nasogastric tube. There is a double-one large lumen for suction and one smaller lumen to act as a sump.
Why do you need a nasogastric tube?
Less commonly, nasogastric tubes can be placed to administer medications or nutrition in patients who have a functional gastrointestinal tract but are unable to tolerate oral intake. This is most commonly in patients who have suffered a stroke or other malady, which has left them unable to swallow effectively.[3] .
What are the complications of nasogastric tubes?
The most common complications related to the placement of nasogastric tubes are discomfort, sinusitis, or epistaxis, all of which typically resolve spontaneously with the removal of the nasogastric tube. As noted previously in the contraindications, nasogastric tubes may cause or worsen a perforation in the setting of esophageal trauma, particularly after caustic ingestion, where extreme caution must be used if the placement is attempted. Blind placement of the tube in patients with injury to the cribriform plate may lead to intracranial placement of the tube.[20] If the tube is being placed for the administration of medications or nutrition, intragastric placement must be confirmed. Introducing medication or tube feeds to the lungs can cause major complications, including death.[2] Even in intubated patients, the NG tube can still be accidentally placed into the airway.[21] Another complication that all those managing nasogastric tubes should be aware of is specifically for the double-lumen nasogastric tubes. These large diameter tubes stent the lower and upper esophageal sphincter open while in place. If the tube becomes obstructed or otherwise malfunctions and is unable to decompress the stomach, it potentially increases the risk of an aspiration event secondary to this stenting effect.[22] Prolonged use of NG tube can cause irritation to the gastric lining, causing gi bleeding.[23] Patients with extensive irrigation with an NG tube can develop electrolyte abnormalities such as hypokalemia.[24] Prolonged pressure on one area of the nare can cause nasal pressure ulcers or necrosis.[25] The tube should be retaped intermittently to prevent this complication.
Why do people use NG tubes?
NG tubes have been used for various reasons in patients with GI bleeding. In the past, NG lavage was thought to help control GI bleeding. However, recent studies have shown that this is not helpful.[7] Another indication for placement of a nasogastric tube is in the setting of massive hematochezia. Given that up to 15% of massive hematochezia is caused by an upper GI bleed, placement of a nasogastric tube, after initiating resuscitation may potentially aid in diagnosis. Of note, an upper GI source of bleeding is only ruled out after aspiration of gastric contents from a nasogastric tube if the fluid is bile tinged. If the fluid is not bile tinged, it is possible that a duodenal ulcer has caused bleeding but also scarred the pylorus causing a gastric outlet obstruction, which prevents the blood from being aspirated from the stomach.[8] However, the placement of an NG tube has not shown to improve patient outcomes in patients with GI bleed. [9]
Why should a nasogastric tube be connected to a suction bucket?
The nasogastric tube should be connected to the suction tubing and the suction tubing connected to a suction bucket before placement of the tube to minimize the risk of spillage of gastric contents. All supplies should be close at hand to minimize unnecessary movement during the procedure. Technique.
How to place a NG tube?
The individual placing the tube should put on nonsterile gloves and lubricate the tip of the tube. A common error when placing the tube is to direct the tube in an upward direction as it enters the nares; this will cause the tube to push against the top of the sinus cavity and cause increased discomfort. The tip should instead be directed parallel to the floor, directly toward the back of the patient's throat. At this time, the patient can be given the cup of water with a straw in it to sip from to help ease the passage of the tube. The tube should be advanced with firm, constant pressure while the patient is sipping. If there is a great deal of difficulty in passing the tube, a helpful maneuver is to withdraw the tube and attempt again after a short break in the contralateral nares as the tube may have become coiled in the oropharynx or nasal sinus. In intubated patients, the use of reverse Sellick's maneuver (pulling the thyroid cartilage up rather than pushing it down during intubation) and freezing the NG tube may help facilitate placement of the tube.[15] Once the tube has been inserted an appropriate length, typically around 55 cm as previously noted, it should be secured to the patient's nose with tape. [16]
Where are nasogastric tubes inserted?
Nasogastric tubes are, as one might surmise from their name, tubes that are inserted through the nares to pass through the posterior oropharynx, down the esophagus, and into the stomach. Dr. Abraham Levin first described their use in 1921.
How long does a nasogastric tube last?
Nasogastric tubes are primarily intended for short-term use, typically for 48 – 72 hours. Patients who require feeding or medication administration via an NG tube for longer than 48 – 72 hours should consider getting a percutaneous endoscopic gastrostomy, or PEG tube, which is a tube that goes directly into the stomach.
Why do we need a nasogastric tube?
Nasogastric tubes may be placed for prophylactic or therapeutic reasons (that is, to prevent problems from occurring, or to fix problems that already exist). Nasogastric tubes can also be used for diagnostic purposes, since it is possible to collect gastric contents using an NG for laboratory analysis.
What are the complications of a nasogastric tube?
More significant complications include erosion of the tube where the tube is anchored, esophageal perforation, pulmonary aspiration, a collapsed lung, or intracranial placement of the nasogastric tube.
What is the tube that carries food?
Nasogastric tubes (NG tubes) are flexible plastic tubes, usually polyurethane or silicone, that carry food or medicine through the nose and down into the stomach, or from the stomach out through the nose.
