The use of strong analgesics for prehospital pain management in children in the region of Southern Denmark: a register-based study.

Background: Acute pain in the prehospital setting is frequent and prehospital pain management presents multiple challenges, especially in children. There is a lack of high-level evidence regarding prehospital pain management in the paediatric population worldwide. In Denmark, this lack of evidence particularly concerns the frequency of the prehospital use of strong analgesics. Guidelines are sparse but there is evidence that prehospital fentanyl may be administered up to 5 µg/kg.

Method: This register-based study investigated the prehospital analgesic treatment in the population under 15 years from January 2017 to December 2022 in the Region of Southern Denmark. Data were extracted from electronic prehospital medical records. The analgesic treatment was characterised by the type of medication, dosage, administration method, and cause of ambulance dispatch. Lastly, response- and transport times were registered.

Results: A total of 28,933 prehospital paediatric medical records were examined. In one in seventeen of all prehospital contacts with children, fentanyl, alfentanil, morphine and/or s-ketamine was administered. Three-quarters of the doses of strong analgesics were administered to patients older than 10 years. Fentanyl was the most frequently administered medication (96.4%). The median fentanyl-equipotent doses of opioids were 1.7 µg/kg adjusted according to standardised patient weight. In 63.4% of cases, the analgesic treatment was administered intravenously.

Conclusion: The doses of opioids as administered by the EMS personnel seem safe as 97% of the doses were within the recommended range and even at the lower end of the recommended range. Although apparently safe, the utilisation of strong analgesics points to a risk of under-treating pain in children.
