Enteral Tube Feeding Ati

ATI Chapter 54: Nasogastric Intubation & Enteral Feedings

Nasogastric intubationinsertion of nasogastric NG tube to manage gastrointestinal dysfunction & provide enteral nutrition
-NG tubes, enteral tube feedings can be delivered via jejunal or gastric tubes
-Insertion & maintenance of nasogastric/enteral feeding tubes is nurse’s responsibility
Nasogastric NG tube-hollow, flexible, cylindrical device inserted through nasopharynx into stomach
Decompression-Removal of gases or stomach contents to relieve distention, nausea, or vomiting
-Tube types: Salem sump, Miller-Abbott, Levin
Feeding-Route administering nutritional supplements when oral/esophageal passageways cannot be used
Tube types: Duo, Levin, Dobbohoff
Lavage-Washing out stomach to treat overdose or ingestion of poison
Tube types: Eweald, Levin, Salem sump
Compression-Applied pressure using internal balloon to prevent hemorrhage
-Tube type- Sengstaken-Blakemore
Procedure: Nursing Actions-Review prescription & purpose, plan for drainage or suction & understand the need for placement for diagnostic purposes
-Identify client & explain procedure
-Evaluate client’s ability to assist and/or cooperate
-Perform hand hygiene
-Set up equipment:
Nasogastric tube- selected according to indication
Tape- to secure dressing
Gloves
Water Soluble lubricant
Cup of water & straw
Catheter- tipped syringe, usually 30 to 60 mL
Basin- to prepare for gag induced nausea
pH test strip or meter- to measure gastric secretions for acidity
Stethoscope- to check placement
Disposable towel- to maintain a clean environment
Clamp or plug- to close tubing after insertion
Suction apparatus- if continuous or intermittent suction is needed
Gauze square- to cleanse outside of tubing after insertion
Safety pin and elastic band- to secure tubing & prevent erroneous removal
Position a disposable towel & basin
Provide privacy
*Intraprocedure: Nursing Actions-Nurse may require assistance with clients who are confused or disoriented
-Assist client to high-Fowler’s position (if possible)
-Assess the nares for best position/route: assess whether or not client has had any nasopharyngeal surgery or septal deviation to determine which naris to use
-Administer topical anesthetic
-Measure tubing- from tip of nose, to top of ear lobe, to tip of the xiphoid, and mark with adhesive tape
-Put gloves on
-Lubricate tip of tubing
-If client is able, have her hold the cup of water with straw in place, and tell her that she will be told when to drink
-Have client hyperextend her head back
-Gradually insert tube
-When resistance is met, apply gentle pressure downward, and proceed beyond curve of nasopharynx
-Have client lean her head forward and begin sipping as insertion continues. Swallowing helps feed the tubing downward toward stomach
-When tubing reaches mark, anchor the tube suing tape or nasogastric claim
-Placement check:
Ask client to talk
Inspect posterior pharynx for coiled tubing
Aspirate gently to collect gastric contents & observe color
Test pH (4 or less is expected)
Confirm placement with an x-ray as prescribed
-Injecting air into tube & when listening over abdomen is not a acceptable practice
-If tube is not in stomach, advance it 5 cm & repeat placement check
-When placement is confirmed, secure tube to nose using tape
-Clamp nasogastric tube or connect it to appropriate suction device
-If client vomits, clear airway & provide comfort prior to continuing
-Salem sump tubing has a blue pigtail for negative air release. Do not insert any substances into blue pigtail, as it will break seal and tubing will leak
Post Procedure: Nursing ActionsThe insertion & maintenance of nasogastric tube is nursing responsibility; but measuring output, providing comfort, & giving oral care can be delegated
Discontinuation/removal-Inform client of order & process, emphasizing that removal is less stressful than placement
-Perform hand hygiene & don gloves
-Remove safety pin from gown, & remove tape-anchoring tube to nose
-Disconnect tubing from suction & claim it
-Provide facial tissues for client
-Instruct client to take & hold deep breath
-Remove tubing with steady continuous pull while client is hold her breath
-Measure & record any drainage
-Clean nares & provide oral care
-Ensure client is confortable
-Dispose of equipment
-Document all relevant information including:
Tubing removal & condition of tube
Volume & description of drainage
Abdominal assessment, including inspection, auscultation, palpation, & percussion
-Last & next bowel movement & urine output
ComplicationsExcoriation (tear or strip) of nares & stomach
-Apply lubricant to nares as needed
-Assess color of nasogastric tube drainage. Report dark “coffee-ground” or blood-streaked drainage to provider immediately
Discomfort
-Rinse client’s mouth with water for dryness
-Throat lozenges may be helpful
-Provide oral hygiene frequently
Occlusion (Obstruction) of NG tube leading to distention
-Irrigate tube per facility protocol to unclog blockages. Tap water may be used with enteral feedings. Have client change position in case tube is against stomach wall
Enteral feedingsis a method of providing nutrients to clients who cannot consume foods orally; Enteral Formulas:
Polymeric1.0 to 2.0 kcal/mL; milk-based, blenderized foods
Whole nutrientformulas prepared by hospital dietary staff or commercially prepared; nutritionally complete
-Only used if client’s GI can absorb whole nutrients
Modular formulas3.8 to 4.0 kcal/mL predigested nutrients
-Not nutritionally complete; provide a single macronutrient
-Easier for partially dysfunctional GI tract to absorb
Specialty formulas-Not nutritionally complete
-Primarily for clients who have hepatic failure, respiratory disease, or HIV infection
Enteral Access Tubes
Nasogastric or Nasointestinal
Therapy duration shorter than 4 weeks; Inserted via nose
Gastrostomy or jejunostomytherapy duration longer than 4 weeks; Inserted surgically
Percutaneous endoscopic gastrostomy PEG or jejunostomy PEJtherapy duration longer than 4 weeks; Inserted endoscopically
Enteral Access Tubes* Surgical & endoscopic insertion presents an increased risk or injury & infection; therefore, they are only indicated for long-term use
*Gastroparesis, esophageal reflux, or history of aspiration pneumonia generally requires intestinal placement*
Nursing Actions: Preparation of Client*Nursing Actions: Preparation of Client
-Review client’s prescription: PCP usually determines the type of tube feeding formula in consultation with dietary staff
-Set up equipment
-Feeding bag
-Tubing
-30 to 60 mL syringe (compatible with tubing)
-Stethoscope
-pH indicator strip
-Infusion pumps (if not a gravity drip_
-Appropriate enteral formula
-Irrigation solution or tap water, according to facility policy
-Gloves
-Supplies for blood glucose (if protocol or orders indication)
Ongoing CarePrepare formula, tubing, & infusion device
-Check expiration dates & note content of formula
-Assure formula is at room temperature
-Setup feeding system via gravity or pump
-Mix or shake formula, fill container, prime tubing, and clamp it
Assist client to Fowler’s position or elevate head of bed to minimum of 30
Monitor Tube Placement
-Check gastric contents for pH. Good indication of appropriate placement is obtaining gastric contents with pH between 0 & 4
-Aspirate for residual volume; intestinal residual should be less than 10 mL, & gastric residual less than 100 mL
-Note appearance of aspirate
-Return aspirated contents or follow facility protocol
Flush tubing with 30 to 60 mL of tap H20
Administer formula
Intermittent feeding: have formula & a 60 mL syringe prepared
-Remove plunger from syringe
-Hold tubing above instillation site
-Open stopcock on tubing, and insert barrel of syringe with end up
-Fill syringe with 40 to 50 mL of formula
-If using a feeding bag, fill bag with total amount of formula prescribed for one feeding, and hang it to drain via gravity until empty (about 30 min)
-If using syringe, hold it high enough for formula to empty gradually via gravity
-Continue to refill syringe until amount prescribed for feeding is instilled
-Follow with 60 to 100 mL of tap water (or amount prescribed) to flush tube & prevent clogging
Continuous-drip Feeding-Connect feeding bag system to feeding tube
-If using a pump, program the instillation rate as prescribed, and set the total volume to instill
-Start pump
-Flush enteral tubing with 30 to 60 mL of irrigant, usually tap water, every 4 to 6 hr, and check tube placement again
-Monitor intake & output & include 24 hr. totals
-Monitor capillary blood glucose every 6 hrs. until max administration rate is reached & maintained for 24 hrs.
-An infusion pump is required for intestinal tube feedings
-Follow manufacturer’s recommendations for formula hang time. Unused formula should be refrigerated & discarded after 24 hrs.
-Gastric residual should be checked every 4 to 8 hr. Facility protocol specifies the actions to take based on amount of residual obtained
-Delegation of this skill to assistive personnel is INAPPROPRIATE
*Complications*When gastric residuals exceeds 100 mL (10 mL for intestinal placement)
-Withhold feeding
-Notify provider
-Maintain semi-Fowler’s position
-Recheck residual in 1 hr or as prescribed
*Diarrhea 3 times or more in 24-hr period

-Provide O2 if indicated
-Monitor client’s vital signs for elevated temperature
-Auscultate breath sounds for increased congestion
-Notify the provider
-Obtain chest x-ray
Skill irritation around tubing site
-Provide skin barrier from any drainage at site
-Monitor tube’s placement
