Burns - Analgesia and dosing

Disclaimer

These guidelines have been produced to guide clinical decision making for the medical, nursing and allied health staff of Perth Children’s Hospital. They are not strict protocols, and they do not replace the judgement of a senior clinician. Clinical common-sense should be applied at all times. These clinical guidelines should never be relied on as a substitute for proper assessment with respect to the particular circumstances of each case and the needs of each patient. Clinicians should also consider the local skill level available and their local area policies before following any guideline. 

Read the full PCH Emergency Department disclaimer.

Aim

To guide PCH Emergency Department (ED) staff in prescribing analgesia in patients with burns.

General principles

  • All children with burns will require analgesia
  • Children with burns requiring admission to hospital will generally require opiates
  • It is essential that the child has been given appropriate long acting medications prior to transfer to the burns unit.
