For all critical and urgent care advice call NSW Aeromedical Control Centre (ACC) on 1800 650 004 or follow your local critical care escalation processes to support care delivered locally.

ADULT critical and specialist care inter-hospital transfer

Guidance on transferring urgent specialist or critical care adult patients to a higher level facility.

Patients may need to transfer when:

  • they have, or are likely to, deteriorate without appropriate resuscitation and supportive management
  • they have a life or limb threatening condition (immediate or urgent)
  • they need clinical care outside the skill set or capabilities of the referring facility
  • the referring facility can only provide temporary stabilisation and management.

Managing the ADULT patient waiting for retrieval or urgent transfer

Information for clinicians on a structured approach to requesting critical care advice and inter-hospital transfer. These resources include guidance on the assessment and clinical management of critical and specialist urgent care patients.

Common infusion table

Critical care advice teams and retrieval teams may advise you to commence vasoactive infusions while waiting for inter-hospital transfer. These medications can be administered via central or peripheral intravenous access.

1. Use 50 mL luer lock syringes with minimum volume tubing

  • Prime lines after infusion syringe solution is drawn up
  • Vasopressors can be administered peripherally in an emergency, recommended for less than 6 hours
  • Vasopressors must be infused via pump with cardiac monitoring

2. Prepare infusions

May be administered peripherally while waiting for central access (less than 6 hours) unless otherwise indicated.

Dilute to 50 mL with sodium chloride 0.9%
Combined total: 50 mL

10 microg/mL
(and 1 mg/mL)

** Central administration recommended.

3. Titrate to effect

Clinical targets:

  • Systolic BP > 90 mmHg
  • MAP > 65 mmHg
  • Urine output > 0.5 mL/kg/hr
  • If hypotension is refractory to vasopressors (greater than one vasopressor required or rapidly increasing requirements) notify retrieval and/or ICU and seek further advice.
  • If using peripheral vasopressor:
    • monitor for signs of extravasation (for example, localised redness, swelling and tenderness)
    • placement of central venous catheter is priority (if feasible and skilled staff are available).

Alternative infusion protocols: Peripheral vasopressors

1. Use 500 mL glucose 5% with infusion pump

  • Prime lines after infusion solution is drawn up
  • Vasopressors can be administered peripherally in an emergency, recommended for less than 6 hours
  • Vasopressors must be infused via pump with cardiac monitoring
  • Use a large peripheral vein at a proximal site on upper limb where possible

2. Prepare infusions

May be administered peripherally while awaiting central access (for less than 6 hours) unless otherwise indicated.

Bariatric patients

In preparation for transport of bariatric patients, provide accurate information to the Aeromedical Control Centre (ACC) or NSW Ambulance. This includes the patient’s weight and maximum width.

All patients above 100 kg require a completed bariatric sizing chart.
