What is the most common type of nasogastric tube used for gastric decompression?

Levin tube

How long can an NG tube be left in?

The use of a nasogastric tube is suitable for enteral feeding for up to six weeks. Polyurethane or silicone feeding tubes are unaffected by gastric acid and can therefore remain in the stomach for a longer period than PVC tubes, which can only be used for up to two weeks.

How do you confirm placement of NG tube?

Nurses can verify the placement of the tube by performing two of the following methods: ask the patient to hum or talk ( coughing or choking means the tube is properly placed); use an irrigation syringe to aspire gastric contents; chest X-ray; lower the open end of the NG tube into a cup of water ( bubbles indicate …

What color is gastric aspirate?

You’ll find that gastric aspirate is usually cloudy and green, tan or off-white, or brown. Intestinal aspirate is generally clear and yellow to bile colored.

How often should you check placement of NG tube?

You should change the position of the NG tube slightly every 24 hours to reduce the risk of skin breakdown. Remember that tube placement should be verified before use if intermittently being used and every 4 hours if being continuously used.

What is the whoosh test?

The “whoosh test” is the air injection trough the tube, if the air is heard in the stomach with a stethoscope, we assume the tube is in the correct position. Gurgling is heard when air enters the stomach, whilst its absence suggests the tip of the NGT is elsewhere (lung, esophagus, pharynx, and so on) [2].

How do you test the pH of gastric aspiration?

Detach the syringe from the tube, replace the end cap of the tube. Detach extension set (if using a Button). Open the clamp on the tube (if present) • Drop the fluid onto the pH indicator strip and read the pH as per manufacturers instructions.

How often do you flush a NG tube?

If you continue to meet resistance, gently move the syringe plunger back and forth to help loosen the clog.

What do you do if an NG tube is displaced?

If you suspect displacement, discontinue tube feedings and notify the physician or NP immediately. A water-soluble contrast study or endoscopic procedure may be required to assess tube location.

What do you flush a NG tube with?

How do you know if you have a nasogastric tube in your lungs?

Locating the tip of the tube after passing the diaphragm in the midline and checking the length to support the tube present in the stomach are methods to confirm correct tube placement. Any deviation at the level of carina may be an indication of inadvertent placement into the lungs through the right or left bronchus.

Why would you irrigate an NG tube?

Preventing tube occlusions is a routine part of nursing practice. Nasogastric tubes used for suction or drainage will be irrigated at least every 2 hours and when needed (PRN) as per patient reports of abdominal discomfort, nausea or vomiting, leaking from tube, gastric distention or gastric distress.

What color should NG tube drainage be?

Check amount, color, consistency, and odor. Hematest drainage to confirm presence of blood in drainage. Normal color of gastric drainage is light yellow to green in color due to the presence of bile.

Can you irrigate an NG tube with distilled water?

Irrigate the nasogastric tube with distilled water. Insert a new nasogastric tube.

What is NG tube suction?

Nasogastric aspiration (suction) is the process of draining the stomach’s contents via the tube. Nasogastric aspiration is mainly used to remove gastrointestinal secretions and swallowed air in patients with gastrointestinal obstructions.

What are the complications of NG tube?

Patients receiving enteral nutrition show several kinds of complications such as diarrhoea, vomiting, constipation, lung aspiration, tube dislodgement, tube clogging, hyperglycaemia and electrolytic alterations.

What does a NG tube feel like?

NG tubes feel really weird at first, it’s odd swallowing and having a tube in your throat, but I found after a short while I forgot it was there. They can hurt your throat after a while.

How do you manage a nasogastric tube?

Managing and preventing a blocked NG tube

  1. Check that the NG tube is not kinked or bent.
  2. Use a 30mL syringe or smaller.
  3. Fill the syringe with warm water and flush into the NG tube using reasonable pressure.
  4. If this doesn’t work, contact your health professional or local hospital for advice.

What is the maximum amount of tube feeding that can be place into an open bag system?

Maximum formula hang time: – Open System: 8 hours – Closed System: 24 hours Page 2 Page 2 of 4 4. Open System: – The amount of feeding in the bag should not exceed the 8 hour feeding volume.

What is a Levin tube used for?

Argyle Levin Stomach Tubes are a (levin type) nasogastric tube used for gastric suction, irrigation and administering medication. The levin stomach tube is made with a clear, thermosenstive pvc tube that has a smooth, rounded tip made to reduce insertion trauma, and allows for easy identification of fluids.

Which tubes are used for intestinal decompression?

Cantor Tube. This is a 10-foot long, single-lumen tube used for intestinal decompression. The Cantor tube has a mercury-weighted rubber tab attached to its perforated tip to help carry the tube through the stomach and intestine.

What type of NG tube is used for continuous suction?

Continuous suction regulators are used with double-lumen (e.g., Salem sump) nasogastric tubes. Set continuous suction as ordered by the primary care provider, or at 60 to 120 mm Hg.

What is the difference between a Levin tube and a Salem sump tube?

The Salem-sump nasogastric tube is a two-lumen piece of equipment; that is, it has two tubes. The Levin tube is usually made of plastic with several drainage holes near the gastric end of the tube. This nasogastric tube is useful in instilling material into the stomach or suctioning material out of the stomach.

Can you feed through a Salem sump tube?

NG tubes are also available in a larger diameter (e.g., Salem sumps). Large-bore NG tubes can be used for feeding or administering medication, but their primary functions are gastric suctioning and decompression.

What is the suction setting for gastric decompression?

When using a one lumen gastric tube to decompress the gastrointestinal tract, a regulator that has an intermittent suction setting, with preset on-and-off cycles must be used. Set the initial level of suction within the “low range” (0 to 80mmHg), starting between 40-60 mmHg. The suction level should not exceed 80 mmHg.
