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

AssessmentIntervention

General appearance/first impressions

Position of comfort

Airway

AssessmentIntervention

Patency of airway

Maintain airway patency

Consider airway opening manoeuvres and positioning

Breathing

AssessmentIntervention

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

AssessmentIntervention

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

AssessmentIntervention
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

AssessmentIntervention
Temperature

Measure temperature

Head-to-toe inspection, including posterior surfaces

Check and document any abnormalities

Fluids

AssessmentIntervention

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

See dehydration focused assessment

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):

  • give quick-acting carbohydrate:
    • Up to 12 months: milk feed and/or 40% glucose gel buccal
    • 12 months and over: sugary soft drink or fruit juice or 40% glucose gel buccal
  • reassess BGL in 15–30 minutes and repeat treatment until BGL over 3 mmol/L

If BGL less than 2 mmol/L OR symptomatic (Red Zone criteria) OR unable to tolerate oral glucose:

  • give 40% glucose gel buccally in incremental doses, as tolerated, while establishing IV access
  • give 10% glucose, 2 mL/kg by slow IV injection once only
  • if IV access delayed, give:
    • Up to 25 kg: glucagon 0.5 mg IM, once only
    • 25 kg and over: glucagon 1 mg IM, once only
  • reassess BGL in 15 minutes

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.
