To access the stomach, duodenum, or jejunum, a practitioner may place a tube through a patients abdominal wall when enteral feedings are needed.1 This procedure may be done surgically or percutaneously.
A gastrostomy or jejunostomy tube is usually inserted during intra-abdominal surgery. The tube may be used for feeding during the immediate postoperative period, or it may provide long-term enteral access, depending on the type of surgery. Typically, the practitioner sutures the tube in place to prevent gastric contents from leaking.
In contrast, a percutaneous endoscopic gastrostomy (PEG) or percutaneous endoscopic jejunostomy (PEJ) tube can be inserted endoscopically without the need for laparotomy or general anesthesia. Typically, the insertion is done in the endoscopy suite or in an interventional radiology department.2 Ultrasound can be used to confirm placement. A PEG or PEJ tube may be used for nutrition, drainage, and decompression. Relative contraindications to endoscopic placement include obstruction (such as an esophageal stricture or duodenal blockage), previous gastric surgery, esophageal or gastric varices, morbid obesity, and ascites.3 These conditions necessitate surgical placement. Long-term feeding devices should be considered when the need for enteral feeding is at least 4 weeks in adults, children, or full-term infants.4
With PEJ tube placement, feedings may begin after 24 hours (or when peristalsis resumes). A PEG tube can be used for feedings within several hours of placement. Current research supports PEG tube usage beginning 4 hours or less after placement in both children and adults.4 Commercially prepared enteral administration sets and pumps allow for continuous formula administration.4
Contraindications to enteral feeding include bowel obstruction, severe ileus, severe upper gastrointestinal bleeding, intractable vomiting or diarrhea, severe hemodynamic instability, gastrointestinal ischemia, and a high output fistula.5 Nursing care for patients receiving intermittent or continuous enteral tube feedings includes providing skin care at the tube site, maintaining the feeding tube, administering the enteral formula, monitoring the patients response to feedings, adjusting the feeding schedule, and preparing the patient for self-care after discharge.
For Intermittent or Continuous Feeding
Fluid-impermeable pad or towel enteral syringe (20-mL or larger)4 prescribed enteral formula tap or purified (sterile, distilled, ultrafiltrated, or ultraviolet-light treated) water4 enteral administration set IV pole gloves labels that state ENTERAL USE ONLY-NOT FOR IV USE oral care supplies tape stethoscope disinfectant pad cleaning supplies for syringe Optional: pH testing equipment, enteral feeding pump, enteral feeding bag, scale, facility-approved disinfectant, tape measure, graduated container.
For Site Care
4" × 4" (10 cm × 10 cm) gauze pads soap and water or normal saline solution water cotton-tipped applicators hypoallergenic tape gloves label Optional: external stabilization device, sterile gauze or foam dressing, skin protectant, tape measure.
Allow the enteral formula to warm to room temperature before administration, because feeding the patient room-temperature formula may reduce the risk of diarrhea.6,7
Inspect all equipment and supplies. If a product is expired, is defective, or has compromised integrity, remove it from patient use, label it as expired or defective, and report the expiration or defect as directed by your facility.
For an Intermittent or a Continuous Feeding
For Site Care
Gastrostomy or Jejunostomy Tube Site
PEG or PEJ Site Care
Instruct the patient and family members or other caregivers in all aspects of enteral feedings, including tube maintenance and site care. Specify signs and symptoms to report to the practitioner, define emergency situations, and review actions to take. Use the demonstration and teach-back method to assess patient and caregiver comprehension of the teaching.
When the enteral tube must be replaced, advise the patient that the practitioner may insert a replacement gastrostomy button after removing the initial feeding tube. The procedure may be done in the practitioners office or an endoscopy or interventional radiology suite of the facility.
As the patients tolerance of tube feeding improves, the patient may wish to try syringe feedings rather than intermittent feedings. If appropriate, teach the patient how to administer the feeding using the syringe method. (See Teaching the patient about syringe feeding.)
Common complications related to enteral feeding tubes include GI and other systemic problems, mechanical malfunction, and metabolic disturbances. Abdominal cramping, nausea, vomiting, bloating, and diarrhea may be related to medication, rapid infusion rate (dumping syndrome), fat malabsorption, intestinal atrophy from malnutrition, or formula contamination, osmolarity, or temperature (too cold or too warm). Constipation can result from inadequate hydration, low fiber intake, fecal impaction, or electrolyte and hormonal imbalance.6
Systemic problems may be caused by pulmonary aspiration, infection at the tube exit site, or contaminated formula.
Typical mechanical problems include tube dislodgment, obstruction, and impairment. For example, a PEG or PEJ tube may migrate if the external bumper loosens. Occlusion may result from incompletely crushed and liquefied medication particles or inadequate tube flushing. The tube may also rupture or crack from age, drying, or frequent manipulation.
Other complications include vitamin and mineral deficiencies, impaired glucose tolerance, and fluid and electrolyte imbalances.5
Document the date, time, and amount of each enteral feeding and the water volume instilled. Maintain total volumes for enteral formula and water separately to allow calculation of nutrient intake. Document the type of enteral formula, infusion method and rate, the patients tolerance of the procedure and formula, and GRV (if used). Also record GI assessment findings. Document any tube feeding problems or complications, the date and time that you notified the practitioner, prescribed interventions, and the patients response to those interventions. Note the date and time that you performed exit site care. Document the exit site care interventions. Record the appearance of the exit site and whether you noted any signs of infection, such as redness, swelling, and drainage. If you observed signs of infection, document the name of the practitioner notified, the date and time of notification, prescribed interventions, and the patients response to those interventions. Document teaching provided to the patient and family (if applicable), their understanding of that teaching, and any need for follow-up teaching.
