Efficacy of inhaled methoxyflurane for procedural analgesia in paediatric burns: a pilot study
Background: Methoxyflurane (MF), a volatile anaesthetic agent is known for its analgesic properties in sub anaesthetic concentrations. It has been used as an analgesic agent for short procedures in both adults and children in the prehospital setting and in the emergency department. We conducted a pilot study to investigate the use of MF for burn dressing changes in children.
Methods: A prospective case series was conducted in the paediatric burns ward amongst children aged 4–9 years. During burns dressing changes MF was administered using a hand-held patient-controlled device. An investigator monitored vital signs together with pain scores, sedation levels and levels of satisfaction of staff.
Results: Twelve patients were enrolled for the study. The majority of the burn wounds were classified as partial-thickness wounds. Methoxyflurane was used as the sole agent for analgesia and sedation for the procedure. No major adverse events were noted. Analgesia and sedation levels were sufficient and appropriate respectively for the majority of the patients during the initial exposure of the wound and the application of the new dressing. However, during the scrubbing of the burn wound analgesia and sedation proved insufficient in four and seven of the patients respectively.
Conclusion: In our setting the use of MF for inpatient burn wound dressing changes may be insufficient as a sole agent in the paediatric patient. We suggest it may be used as an adjunct to current practice. Further, larger studies are required to delineate the appropriate role MF can play in the paediatric burns setting.
