    Flashcards

    Nasogastric Tube (NGT)

    A thin, flexible tube inserted through the nose to the stomach, used for feeding, draining, and medication administration.

    NGT Insertion – Positioning

    The child should be positioned supine, with the head elevated 30-40 degrees. Infants/younger children may need holding.

    NGT Insertion - Feeding Indications

    NGTs are used to feed children who can't eat normally, such as those with trouble swallowing, oral surgery, or malnutrition.

    NGT Insertion – Procedure

    The procedure involves inserting a lubricated tube through the nose, esophagus, and into the stomach. Aspirate gastric contents for confirmation. Carefully monitor and remove the NGT if needed.

    Orogastric Tube (OGT)

    A tube inserted through the mouth to the stomach, often for the same indication as an NGT.

    NGT Positioning - Children

    Children's NGT insertion needs careful positioning, often with head elevation. Holding in infants/young children is important.

    Study Notes

    Nasogastric Tube (NGT)

    • Definition: A medical procedure involving inserting a thin, flexible plastic tube through the nose, esophagus, and into the stomach.
    • Alternative: Orogastric Tube (OG) is similar, but the tube enters through the mouth.
    • Purpose: Used for drainage, diagnostics, therapeutics, and feeding.
    • Indications for use:
      • Unable to take oral feedings.
      • Oral surgery (e.g., cleft lip/palate, jaw fracture).
      • Difficulty swallowing.
      • Malnutrition.
      • Premature babies.
      • Vomiting/anorexia nervosa.
      • Aspiration of gastric contents (e.g., poisoning).
      • Medication administration.
      • Unconsciousness.
      • Endotracheal intubation.

    Equipment

    • Kidney tray: For collecting waste.
    • Cotton-tipped applicators: For cleaning nostrils.
    • Ryle's tube: Used for feeding or drainage.
    • Lubricant (water-soluble jelly or glycerin): To prevent friction.
    • Scissors: For cutting.
    • Adhesive plaster or tape: For securing.
    • Measuring cup/glass: For measuring feed amounts.
    • Sterile syringe (10-20 mL): For aspirating contents or administering medications.
    • Paper bag: For collecting waste.
    • Glass of warm water: To warm feed to body temperature.
    • Tongue blade: Used for examination.
    • Suction apparatus: To clear airways as needed.
    • Bowel with water: To check NG tube placement.
    • Clamp: To prevent leakage of gastric contents.

    Pediatric Positioning

    • Supine: Lying flat.
    • Head elevated: Bed head elevated 30-40°. Options are sitting upright for older children.
    • Infant/younger child holding: Requires parental consent.

    Procedure

    • Identify the child.
    • Explain the procedure.
    • Make the patient comfortable.
    • Position a face towel: Across the chest and under the chin.
    • Keep a kidney tray ready: For vomit.
    • Clean the nostrils.
    • Assemble supplies properly.
    • Proper hand washing.
    • Check tube patency.
    • Measure placement: From nose tip to xiphoid process.
    • Lubricate the tube.
    • Insert slowly: Give sips of water and guide with swallows (adjust amount to child's age)
    • Check placement: Aspirate stomach contents and check pH. X-ray is an option.
    • Monitor input/output.
    • Remove the tube: If blockage occurs or if no longer needed.

    Oral Hygiene

    • Frequency: Every 4-6 hours.
    • Purpose: Prevents infection.

    Non-Radiological Verification of Placement

    • pH test: Aspirate 2 mL of stomach contents, and test using pH paper.
      • pH ≤5.5 indicates correct placement
      • pH >5.5 requires radiology confirmation
    • Gastric auscultation: Using a syringe, inject 3mL of air, while listening with a stethoscope.
      • If you hear whooshing, gurgling, or popping sounds, the tube is correctly positioned.

    Contraindications

    • Gastric surgery.
    • Ulcers.
    • Tracheo-esophageal fistula.
    • Esophageal surgery
    • Recent nasal/facial surgery
    • Polyps in nose
    • Deviated nasal septum
    • Patient on anticoagulant therapy.
