nasogastric tube
TRANSCRIPT
NASOGASTRIC TUBE
Purposes
1. To decompress stomach by removing fluids and/or gas to promote abdominal comfort2. To allow surgical anastamoses to heal without distention3. To decrease risk of aspiration4. To administer medications to clients who are unable to swallow5. To provide nutrition by acting as a temporary feeding tube6. To irrigate the stomach and remove toxic substances, such as poisoning
Place patient in a High Fowlers positionMeasure: NEX (usually 22-26 inches for adults)
plus 2 inches for tall patients. Lubricate with water solubleAsk the client to hyperextend the neck,
advancing the tube toward the nasopharynx Instruct client to tilt the head forward when the
tube is felt in the oropharynx(throat)Offer small sips of water from a glass with straw
and encourage to swallowStop if the patient gags, wait for few min.
before proceedingWithdraw if gagging continuesAssess for correct placement by:
Check pH: should be less than 4.0Inserting 5-10 ml of air into a stethoscope
placed over the stomach and listen for a swooshing sound
Taking X-ray: MOST RELIABLE METHODSecure tube to the bridge of the nose with tape
and to the gown
INSERTION
Usually up to 2 weeks use only (short term)
Clean but not sterile procedure
Mouth care neededReport coffee ground material (digested blood)
Check for placement and patency
Clamp tube when ambulating
Key points
Hold feeding if >50% residual from previous hour (adults) or >25% (children)
Flush tube with water before and after feeding
Use pump to control rate of tube feedingAdminister fluid at room temperatureChange bag Q8 hours for continuous feeding
Elevate head of bed while feeding is running
Check patency Q4 hoursGood mouth care
Nasogastric Tubes:
Linton-Nachlas—4-lumen, used for bleeding esophageal varices
Keofeed/Dobhoff—soft silicone, used for long-term feedings
Purpose Example of Use
Key Points
LEVIN TUBE
- Single lumen
Inserted into stomach to decompress by removing gastric contents and air Used for feeding when unable to swallow
Any abdominal or other sx after which peristalsis is absent for a few days GI hemorrhage CA of the esophagus Early post-op for pt who had laryngectomy or radical neck dissection
Low intermittent suction Irrigate prn with NSS
Purpose Example of Use
Key Points
SALEM – SUMP
- Double lumen air vented tube to provide constant inflow of athmos-pheric air, and to protect gastric mucosa from trauma of suctioning
Gastric decompression with continuous suction
Same as levin tube
•With continuous suction (25mmHg)•If leak occurs in the vent (blue tubing), instill 30 ml air into vent and irrigate main with NSS.•Do not clamp vent
NG Irrigation Tubing: Verify placement of tubeInsert 30-50 cc of normal saline into tubeIf feel resistance, change patient position, check for kinks
Withdraw solution or record amount as input
NG removal:Clamp tubeRemove tapeInstruct patient to exhaleRemove tube with smooth, continuous pull
Purpose Example of Use
Key Points
LAVACUATOR
• Orogastric w/ large suction lumen and smaller lavage vent• Removes toxic substances from stomach
Ingestion of poison
• Continuous suction• Irrigation solution enters the lavage lumen while stomach contents are removed through the suction lumen

A patient with NGT after gastric resection complains of severe nausea and absence of drainage for the past 4 hours is noticed. The most appropriate nursing action would be toA. Repositioning the patientB. Irrigating the tube with NSSC. Notifying the physicianD. Giving antiemetic medication
A patient with NGT after gastric resection complains of severe nausea and absence of drainage for the past 4 hours is noticed. The most appropriate nursing action would be toA. Repositioning the patientB. Irrigating the tube with NSSC. Notifying the physicianD. Giving antiemetic medicationRationale: C. N&V is not a normal observation after NGT insertion. The most appropriate action is to notify the physician. Positioning the tube or irrigating is not prescribed because the NGT is placed directly in the suture line and may cause pressure on it.
