Study Notes
Nasogastric Tube (NGT)
- A thin, flexible plastic tube inserted through the nose, esophagus, and into the stomach.
- Used for feeding, draining, or administering medication.
- Purpose includes drainage, diagnostic, therapeutic, and feeding.
- Another type is the Orogastric Tube (OG), inserted through the mouth.
Indications for NGT Use
- Feeding infants and children unable to eat orally.
- Conditions involving oral surgery (cleft lip/palate, jaw fracture, difficulty swallowing).
- Malnutrition.
- Premature babies.
- Vomiting (e.g., anorexia nervosa).
- Aspiration of gastric contents (e.g., poisoning).
- Medication administration.
- Difficulty swallowing (dysphagia).
- Unconsciousness.
- Endotracheal intubation.
Equipment for NGT Insertion
- Kidney tray (for waste).
- Cotton-tipped applicators (for cleaning nostrils).
- Ryle's tube (a specific type of nasogastric tube).
- Lubricant (water-soluble jelly or glycerin).
- Scissors and adhesive plaster/tape.
- Measuring cup/glass.
- Sterile syringe (10-20 ml).
- Paper bag (for waste collection).
- Glass of feed in warm water (to maintain body temperature).
- Tongue blade.
- Suction apparatus (to clear airways).
- Bowel of water (to check tube placement).
- Clamp (for preventing leakage of gastric contents).
Procedure for NGT Insertion
- Identify and explain the procedure to the child/parent.
- Place the child in a comfortable position (supine, head elevated).
- Arrange a face towel across the child's chest.
- Keep a kidney tray on hand to collect any vomiting.
- Clean nostrils.
- Prepare equipment.
- Wash hands properly.
- Check the patency of the tube.
- Measure tube length (nose to xiphoid process).
- Lubricate the tube.
- Insert the tube slowly.
- Encourage swallowing with water sips.
- Insert the tube 3-4 inches each time and confirm placement in the stomach.
- Aspirate gastric contents and check pH (or radiographically).
Post-Insertion Care
- Monitor input and output.
- Teach the mother how to care for the tube.
- Monitor the time, date, amount, and content of feeding. Record appropriately.
- Teach proper oral hygiene (every 4-6 hours).
- Remove the tube when needed or blocked.
Contraindications for NGT Insertion
- Recent gastric surgery.
- Ulcers.
- Tracheoesophageal fistula.
- Recent esophageal surgery.
- Nasal polyps.
- Recent nasal or facial surgery.
- Deviated nasal septum.
- Patient on anticoagulant therapy.
Non-Radiologic Verification Methods
-
Method 1: pH Test: Aspirate 2ml of stomach contents. Test the pH with pH paper. pH <5.5 confirms placement; >5.5 requires X-ray confirmation.
-
Method 2: Gastric Auscultation: Inject 3mL of air into the tube while listening with a stethoscope for whooshing/gurgling/popping sounds; this indicates the tube's correct positioning.
-
If the tube placement is doubtful, remove it and re-attempt placement.
