A physician has ordered gavage feeding every 4 hours for A 12-week-old infant with failure to thrive.

الشرح

Core Concept: For infant gavage feeding, the feeding tube insertion length is measured using the NEX method: from the tip of the nose to the earlobe and then down to the xiphoid process. This estimates the distance needed for the tube tip to reach the stomach and reduces the risk of pulmonary placement or post-pyloric insertion.

Clinical Presentation: • Failure to thrive may present with poor feeding, poor weight gain, dehydration, and delayed growth. • Tube-feeding complications can include aspiration, vomiting, tube misplacement, mucosal trauma, and respiratory distress.

Diagnosis: 1) First-line: measure the NEX distance externally before insertion and secure the tube at the measured length. 2) Gold standard: radiographic confirmation of tube tip position; bedside gastric aspirate pH testing supports correct gastric placement when X-ray is not immediately available.

Management: Acute - measure correctly, insert the tube gently, verify placement before each feed, and stop feeding if respiratory distress occurs. Definitive/long-term - scheduled gavage feeds, strict intake/output monitoring, daily weights, and caregiver education on safe feeding techniques.
