POLICY
1.1
Registered Nurses will insert or remove a Nasogastric (NG) tube as ordered by a
physician.
1.2
Registered nurses will not insert a NG tube if:
1.2.1
the patient has or is suspected to have a basal skull fracture, cribriform
plate fracture or facial fracture.
1.2.2
there is danger of perforation (recent esophageal repair, esophageal
varices, esophageal strictures, gastric surgery).
1.2.3
a metal guide or stilette is required for insertion.
1.2.4
the patient does not have a gag reflex unless RN is certified in procedure.
Refer to policy - Insertion of a Nasogastric Tube Without a Gag Reflex.
1.3
Tube placement will be assessed following insertion, q shift, prior to instillation
and prn.
1.4
An order must be obtained from a physician for the type and amount of suction or
the enteral feed solution and volume.
1.5
Skin condition at tape site will be assessed q shift.
PURPOSE
2.1
2.2
To remove fluid and gas from the G.I. tract.
To determine the amount of pressure and motor activity in the G.I. tract
(diagnostic studies).

2.3
To treat patients with mechanical obstruction and bleeding within the upper G.I.
tract.

To administer medications and enteral feeding.
2.5

PROCEDURE
3.1
Obtain Supplies:
•
•
•
•
•
•
•

•
•
•
•
•
•
Patent NG tube of required size (levine or salem sump)
water soluble lubricant
60ml catheter tip syringe Neonates: 12 - 20 ml syringe
non-sterile gloves
stethoscope
tape or NG tube anchoring device
thread (optional)
incontinent pad
glass of water and straw
safety pin and elastic band
anti-reflux valve (for use with salem sump)
kidney basin
feeding equipment
suctioning equipment
3.2
Position patient in high fowler’s position, unless contraindicated. Patient may be
positioned in left lateral position if unable to sit up.
Neonates: Place in “sniffing” position.
3.3
Measure to determine the length of tube needed to reach the stomach. Using the
nasogastric tube, measure from the tip of the nose to the ear lobe and down to the
tip of the xiphoid process. Indicate this length by noting the marking on the tube,
or by placing tape at that point.
3.4
Place incontinent pad over patient’s chest and keep kidney basin available.
3.5
Examine the nares and obtain history of nasal trauma if possible to determine
which nostril is most patent.
3.6
Glove.

Policy & Procedure: Nasogastric Tube Insertion
And Care Of
3.7
Lubricate tube along the first 10 cm with water soluble lubricant.
Neonates: Lubricate tube along the first 5cm with sterile water.
3.8
Tilt the head back unless contraindicated and gently insert tube through the nose
toward the occiput.
Neonates: Place in “sniffing” position and gently insert tube downwards through
mouth or nose.
3.9
When the tube reaches the nasopharynx (back of throat), have patient tilt their
chin on their chest and instruct the patient to dry swallow or sip water if not
contraindicated. Infants may suck on a soother.
3.10
Continue to advance the tube firmly and steadily while patient swallows until the
predetermined length is reached.
3.11
To assess tube placement:
3.11.1
aspirate gastric contents with 60 ml syringe. (pH monitoring of
gastric contents may be done)
3.11.2
ausculate for a rumbling sound in the stomach while injecting a
volume of air into the NG tube. The volume of air will vary with
the patient’s size. i.e. neonates 0.5 ml, infants 1-2 ml, older
children 3 - 5 ml, adults 10 - 20 mls
NOTE: This method may be unreliable.
3.11.3
chest x-ray for tube placement as ordered by physician
NOTE: With the salem sump tube, the blue salem port helps keep
the mucosa from being drawn into the tube by suction. Only air
should be instilled into the blue sump port. Flush or aspirate fluid
through the clear port.
3.12
Fasten tube securely. A NG tube anchoring device, tape or a thread and tape may
be used.
NOTE: Do not tape the external length of the ng tube to the patient’s face as
prolonged taping in this position can cause ulcers of the nasal mucosa.
3.13
Wrap elastic band around nasogastric tube and pin to patient’s gown to secure the
tube and decrease tension.
3.14
After confirmation of tube placement, connect NG tube to suction, straight
drainage, tube feed or clamp as ordered.
3.15
Connect the anti-reflux valve to the blue salem port to prevent reflux of
nasogastric contents (if applicable).

Policy & Procedure: Nasogastric Tube Insertion
And Care Of
3.16
Chart on the appropriate nursing record:
• date and time of tube insertion
• size of tube used
• name of person performing the procedure
• attachment to suction, straight drainage, tube feed or clamped
3.17
Report to physician if:
• unable to insert the tube
• any complications occur
3.18
Irrigate the tube if:
• gastric content leaks from the blue port or the tube is blocked. Flush the clear
lumen with 30 mls of NS and instill 10cc of air into the blue lumen. Record
the amount of irrigation on the Fluid Balance Sheet.
3.19
To remove:
• clamp the NG tube by kinking with your hand
• instruct the patient to hold breath, or if unable to follow instruction remove on
expiration
• withdraw the tube steadily – then wrap in incontinent pad and dispose
• have patient cough to clear airway of secretions or suction if required
