Gastrostomy (PEG Tube)

Surgical opening through the abdominal wall into the stomach for feeding

Definition

A gastrostomy is a surgical opening through the abdominal wall into the stomach, typically for long-term enteral feeding. The most common type is the percutaneous endoscopic gastrostomy (PEG) tube, placed endoscopically.

Indications

  • Dysphagia (stroke, ALS, head/neck cancer)
  • Prolonged mechanical ventilation
  • Failure to thrive
  • Severe cognitive impairment with aspiration risk

Nursing Care

  • Monitor site for infection (redness, drainage, pain)
  • Clean site daily with soap and water; rotate tube slightly to prevent adhesion
  • Verify placement before each feeding (residuals, gastric pH)
  • Elevate HOB 30 to 45° during and 60 minutes after feedings
  • Flush with 30 mL water before/after feedings and medications
  • Give medications in liquid form when possible; crush tablets if allowed
  • Monitor for dislodgement. If tube falls out, cover site and notify provider within 30 minutes (can close rapidly)

NCLEX Relevance
