Place the client in high-Fowler’s position Measure from tip of nose to earlobe to
xiphoid process to determine the length of insertion and mark with tape
Lubricate tube about 3 inches with a water-soluble jelly only (oil-soluble is not used), to prevent the development of pneumonia if the tube accidentally slips into the bronchus
Instruct the client to bend the head forward, which closes the epiglottis and opens the esophagus
![Page 10: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/10.jpg)
Insert into nostril, advance backward and through the nasopharynx
Have the client take a sip of water and advance tube as the client swallows
Do not force the tube If the client experiences any respiratory
distress (coughing or choking) during insertion, pull back on the tube and wait until the distress subsides
![Page 11: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/11.jpg)
Advance until taped mark is reached; tape in place when correct placement is confirmed
If feedings are prescribed, x-ray confirmation should be done prior to initiating feedings
When gastrointestinal (GI) tubes are attached to suction, suction may be continuous or intermittent, with a pressure not exceeding 25 mmHg as prescribed by the physician
![Page 12: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/12.jpg)

The most reliable method to determine placement is by x-ray
Assess placement every 4 hours and before administering feedings or medications
Assess placement by aspirating gastric contents and measuring the pH, which should be 4 or less (pH values greater than 6 indicate intestinal placement)
Inserting 5 to 10 ml of air into the NG tube and listening for the rush of air over the stomach with a stethoscope is an alternative method for assessing placement, but is not as reliable as an x-ray or checking gastric pH
![Page 14: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/14.jpg)
Check residual volumes every 4 hours, before each feeding, and before giving medications
Aspirate all stomach contents (residual) and measure amount
Reinstill residual feeding to prevent excessive fluid and electrolyte losses unless the residual volume appears abnormal
![Page 15: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/15.jpg)
Performed every 4 hours to check the patency of the tube
Assess placement before irrigating Gently instill 30 to 50 ml of water or normal
saline (NS) (depending on agency policy) with an irrigation syringe
Pull back on the syringe plunger to withdraw the fluid to check patency; repeat if tube remains sluggish
![Page 16: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/16.jpg)
Ask the client to take a deep breath and hold
Remove the tube slowly and evenly over the course of 3 to 6 seconds (coil the tube around the hand as it is being removed)

Position the client in high-Fowler’s and on the right side if comatose
Warm feeding to room temperature to prevent diarrhea and cramps
Aspirate all stomach contents (residual), measure the amount, and return the contents to the stomach to prevent electrolyte imbalances
Check physician’s order and agency policy regarding residual amounts; usually if the residual is less than 100 to 150 ml, feeding is administered; if greater than 150 ml, hold the feeding
![Page 26: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/26.jpg)
Assess tube placement by aspirating gastric contents and measuring the pH (should be 4 or less)
Assess bowel sounds; hold feeding and notify the physician if bowel sounds are absent
Use a feeding pump for continuous or cyclical feedings
For bolus feeding, leave the client in a high-Fowler’s position for 30 minutes after feeding
For a continuous or cyclical feedings, keep the client in a semi-Fowler’s position at all times
![Page 27: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/27.jpg)

Shake the formula well prior to inserting into container
![Page 28: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/28.jpg)
Always assess placement of the tube prior to feeding
Always assess bowel sounds; do not administer any feedings if bowel sounds are absent
If an obstruction occurs, try flushing with water, saline, cranberry juice, ginger ale, or cola, if not contraindicated, after checking placement
![Page 29: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/29.jpg)
Add a drop of methyline blue to the feeding, particularly with clients who have endotracheal or tracheal tubes; suspect tracheoesophageal fistula when blue gastric contents appear in tracheal excretion and if this is noted, notify the physician immediately
Administer feeding at prescribed rate, or via gravity flow (intermittent, bolus feedings) with a 60-ml syringe with the plunger removed
Gently flush with 30 to 50 ml of water or normal saline (depending on agency policy) with the irrigation syringe after the feeding

Triple-lumen gastric tube with an inflatable esophageal balloon, an inflatable gastric balloon, and a gastric aspiration lumen
The gastric balloon applies pressure at the cardioesophageal junction to directly compress gastric varices and to decrease blood flow to esophageal varices; traction is applied to maintain the gastric balloon in place
The esophageal balloon directly compresses esophageal varices
![Page 49: Gi Procedures](https://reader033.fdocuments.net/reader033/viewer/2022061119/546adbc2b4af9fe2178b4776/html5/thumbnails/49.jpg)
If bleeding is not stopped with inflation of the gastric balloon, the esophageal balloon is inflated to 25 to 45 mmHg
An x-ray of upper abdomen and chest confirms placement
Gastric contents are aspirated by gastric lavage or intermittent suction via the gastric aspiration port
A nasogastric tube is also inserted in the opposite naris to collect secretions that accumulate above the esophageal balloon
