Post-Gastrostomy Tube Care Protocol
For the first 5-7 days after G-tube placement, perform daily monitoring and aseptic wound care of the exit site, keeping it clean and dry, then initiate feeding 3-4 hours post-procedure once correct tube position is verified and the patient is medically stable. 1
Immediate Post-Procedure Care (Day 1)
Feeding Initiation
- Begin enteral feeding 3-4 hours after tube placement once the patient is medically stable and correct tube position is confirmed 1
- Verify tolerance to the prescribed volume and formula before discharge 1
- Note that 1-2% of patients may develop prolonged ileus requiring delayed feeding 1
Initial Wound Management
- Do NOT apply traction to the tube system during the first 24 hours - this does not improve gastric-to-abdominal wall adaptation and is unnecessary 1
- Ensure the external fixation plate allows at least 5mm (0.5-1cm) of free tube movement to prevent pressure necrosis 1, 2
- Position the external bolster with loose contact against the skin - excessive pressure increases infection risk and can cause mucosal ulceration 1
Days 1-7: Active Wound Healing Phase
Daily Exit Site Care
- Monitor the stoma site daily for bleeding, pain, erythema, induration, leakage, and inflammation 1
- Cleanse the site daily using 0.9% sodium chloride, sterile water, or freshly boiled and cooled water to remove debris 1
- Apply a sterile Y-dressing under the external disc plate that does not shed fibers, followed by a breathable (non-occlusive) dressing 1
- Avoid occlusive dressings as they create a moist environment promoting skin maceration 1
- Alternative option: Use glycerin hydrogel or glycogel dressing instead of classical aseptic wound care 1
Tube Flushing Protocol
- Flush the tube with 40ml of water after each feed or medication administration to prevent residue buildup and occlusion 2
- This is critical for maintaining tube patency, especially in small-caliber tubes 2
After Week 1: Maintenance Phase
Reduced Wound Care (After 5-7 Days)
- Reduce dressing changes to 1-2 times per week once the stoma tract has healed 1
- Cleanse the site using soap and water of drinking quality 1, 2
- Alternative option: Dressings can be omitted entirely and the site left open 1
- Ensure the tube is dried well after washing before applying new dressing 2
Weekly Tube Manipulation (After Week 1)
- Rotate the tube daily once the tract has healed 1
- Move the tube inward at least once weekly (at least 2cm, up to 10cm) 1
- During dressing changes, push the tube 2-3cm ventrally and carefully pull back to the resistance of the internal fixation flange to prevent buried bumper syndrome 2, 3
Monitoring for Complications
High-Risk Patients Requiring Extra Vigilance
- Patients with diabetes, obesity, poor nutritional status, chronic corticosteroid therapy, or immunosuppressive therapy are at increased risk for infection 1
- Patients with dementia or delirium require preventive measures to protect the tube from inadvertent removal 1
Signs of Infection
- Watch for loss of skin integrity, erythema, purulent/malodorous exudate, fever, and pain 1
- If infection is suspected: Apply topical antimicrobial agent to the entry site and surrounding tissue 1
- If infection persists: Add systemic broad-spectrum antibiotics (avoid topical antibiotics) 1
- Swab the area for bacterial and fungal cultures to guide treatment 1
- If infection cannot be resolved: Remove the tube 1
Managing Leakage
- Leakage around the stoma can cause skin irritation and pain 3
- Use a hydrocolloid wafer as a keyhole dressing for skin protection 3
- Apply zinc oxide or stoma adhesive powder to prevent local skin irritation 1
- Use foam dressing rather than gauze (foam lifts drainage away from skin) 1
Critical Safety Considerations
Tube Replacement Timing
- Before 4 weeks: Inadvertent removal is an emergency requiring endoscopic or radiological replacement 1
- After 4 weeks: Direct replacement can be safely attempted through the mature tract before it closes 1
- The gastric-to-abdominal wall adherence normally takes 7-14 days but may be delayed in patients with impaired wound healing (malnutrition, ascites, corticosteroid treatment) 1
Position Verification After Replacement
- Confirm proper position using water-soluble contrast study, pH confirmation of gastric content (pH ≤5), or assess for resistance-free irrigation with 3-50ml sterile water 1
- Check external tube length and perform manipulation via rotation and in-out movement 1
Common Pitfalls to Avoid
- Never use cola or pancreatic enzymes to unclog tubes - sugar content enhances bacterial contamination risk 2
- Never apply excessive tension with the external bolster - this causes pressure necrosis and increases infection risk 1
- Never skip the 40ml flush after medications or feeds - insufficient water volume leads to tube occlusion 2
- Never ignore persistent pain beyond 48 hours - evaluate for wound infection, peritonitis, or tube malposition 3
