Any person, 4 weeks to 15 years, presenting with partial or complete dislodgement of a gastric tube (PEG) which has been established for over 2 months or displacement of a long-term nasogastric tube (NGT).
This protocol is intended to be used by registered and enrolled nurses within their scope of practice and as outlined in The Use of Emergency Care Assessment and Treatment Protocols (PD2024_011). Sections marked triangle or diamond indicate the need for additional prerequisite education prior to use. Check the medication table for dose adjustments and links to relevant reference texts.

Clinical assessment and specified intervention (A to G)
If the patient has any Yellow or Red Zone observations or additional criteria (as per the relevant NSW Standard Emergency Observation Chart), refer and escalate as per local CERS protocol and continue treatment.
Position
Assessment | Intervention |
---|---|
General appearance/first impressions | Position of comfort |
Airway
Assessment | Intervention |
---|---|
Patency of airway | Maintain airway patency Consider airway opening manoeuvres and positioning |
Breathing
Assessment | Intervention |
---|---|
Respiratory rate and work of breathing Consider auscultation of chest (breath sounds) Oxygen saturation (SpO2) | Assist ventilation as clinically indicated Apply oxygen to maintain SpO2 over 93% |
Circulation
Assessment | Intervention |
---|---|
Perfusion (capillary refill, skin warmth and colour) Heart rate Blood pressure Cardiac rhythm | Assess circulation Attach cardiac monitor if BP/HR are within the Yellow or Red Zones, or where clinically relevant, e.g. irregular pulse, palpitations, syncope, shock, respiratory compromise, cardiac history or clinical concern Consider 12 lead ECG |
Disability
Assessment | Intervention |
---|---|
AVPU | If AVPU shows reduced level of consciousness, continue to assess GCS, pupillary response and limb strength |
GCS, pupillary response and limb strength | Obtain baseline and repeat assessment as clinically indicated |
Pain | Assess pain. If indicated, give early analgesia as per analgesia section then resume A to G assessment |
Exposure
Assessment | Intervention |
---|---|
Temperature | Measure temperature |
Head-to-toe inspection, including posterior surfaces | Check and document any abnormalities |
Fluids
Assessment | Intervention |
---|---|
Hydration status | Assess fluids, in and out. Document on fluid balance chart. Include gastrointestinal losses If moderate to severe dehydration: give sodium chloride 0.9% at 20 mL/kg IV/intraosseous bolus once only, maximum dose 1000 mL |
Glucose
Assessment | Intervention |
---|---|
BGL |
Measure BGL if PEG/NGT out for one or more missed feeds. See medication table for 40% glucose gel dosing If BGL between 2 mmol/L and 3 mmol/L and NOT symptomatic (Yellow Zone criteria):
If BGL less than 2 mmol/L OR symptomatic (Red Zone criteria) OR unable to tolerate oral glucose:
Once stabilised, give patient long-acting carbohydrate and continue to check BGL hourly, or as clinically indicated |
Repeat and document assessment and observations to monitor responses to interventions, identify developing trends and clinical deterioration. Escalate care as required according to the local CERS protocol.
Focused assessment
Complete a dehydration focused assessment.
Consider an abdominal focused assessment.
Gastric tube – ballooned PEG assessment
- Assess gastric tube insertion site for:
- Signs of infection, including erythema, discharge or localised swelling
- Surrounding skin integrity.
- Identify current tube type and size. Use tube provided by parent or carer, if available.
Nasogastric tube assessment
- Assess facial skin for signs of breakdown or pressure areas before insertion.
- Alternate nostril insertion where possible.
Precautions and notes
- A displaced gastrostomy tube or device demands prompt attention. A replacement tube should be reinserted within 4 hours of dislodgement. If nothing is placed back in the tract, the stoma may close over, and the patient may require an operation to replace the gastrostomy.
- If the tube has been dislodged for longer than 4 hours, surgical input may be required.
Interventions and diagnostics
Specific treatment
Only nurses who have completed the required education and training may attempt to reinsert the gastric or nasogastric tube.
Gastric tube: ballooned PEG reinsertion
If device has been dislodged for longer than 4 hours and/or no replacement available:
- Place a foley catheter of equal size or smaller to the gastrostomy tube.
- Secure with tape to prevent migration of the tube.
If trained in reinsertion of gastric tube:
- A replacement tube or appropriate temporary tube should be reinserted within 4 hours of dislodgement
- Attempt reinsertion once only.
- Balloon tubes can usually be replaced by a clinician, parent or carer trained in tube reinsertion.
- Apply a small amount of lidocaine (lignocaine) 2% gel, topically, before reinserting. If pain exceeds expected level escalate as per local CERS protocol to discuss pain management plan. Ensure there is a temporary tube, foley catheter, in place.
- Consider sedation with nitrous oxide for reinsertion.
- Confirm placement of tube by using appropriate pH indicator paper. pH must be 4.0 or below before device is used.
- If the patient is unsettled post re-feeding, consider tube or leakage into the peritoneum and/or bowel ileus.
Nasogastric tube insertion
- If the tube is not placed after 2 attempts, await medical or nurse practitioner assessment.
- Confirm placement of tube by using appropriate pH indicator paper. pH must be 4.0 or below before device is used. Consider chest x-ray if testing is inconclusive.
Analgesia
If pain score 1–6 (mild–moderate):
Give paracetamol 15 mg/kg orally or enterally once only, maximum dose 1000 mg. Discuss the best route with parent or carer before administration
and/or ibuprofen, if 3 months and over, 10 mg/kg orally once only, maximum dose 400 mg
If severe pain present, give analgesia and escalate as per local CERS protocol.
Consider non-pharmacological pain relief (appendix).
Procedural analgesia
For pain relief required during procedures only, not used to replace appropriate analgesia.
Sucrose 24%
- 1–18 months: give 1–2 mL orally per procedure
- Maximum dose:
- 1–3 months: up to 5 mL in 24 hours
- 3–18 months: up to 10 mL in 24 hours.
Repeat as needed up to the maximum dose.
Nitrous oxide and oxygen mix inhalation
Only give nitrous:
- if required education and training have been completed
- according to state and local guidelines
- when an additional trained clinician is available to complete the procedure.
12 months and over:
- Attach oxygen saturation probe for monitoring.
- Apply 100% oxygen with face mask, ensuring adequate seal. Aim for smallest fitting mask.
- Give 70% nitrous oxide with 30% oxygen for 3–4 minutes before starting procedure.
- If wall nitrous oxide/oxygen is unavailable, pre-mixed 50% nitrous oxide with 50% oxygen (Entonox) can be used.
- After procedure: give 100% oxygen for 3–5 minutes, to prevent diffusion hypoxia.
- If the nitrous oxide is removed for over 30 seconds at any stage: apply 100% oxygen for 3 minutes, to prevent diffusion hypoxia.
Radiology
- pH testing inconclusive: CXR, to confirm placement of nasogastric tube
If there is concern for urgent radiology, escalate as per local CERS protocol.
Pathology
Not usually indicated. If there is concern for urgent pathology, escalate care as per local CERS protocol.
Medications
The patient’s weight is mandatory for calculating fluid and medication doses.
The Broselow Tape or APLS weight table (appendix) can be used only in circumstances where the patient cannot be weighed.
The shaded sections in this protocol are only to be used by registered nurses who have completed the required education.
