In pre-hospital settings, the administration of analgesics is often delayed because of difficult patient access (incarceration), difficulty finding a venous pathway or patient refusal.~An optimization of the management of pain in urgency is therefore still necessary.~A side from nitrousoxide of which usage remains restrictive, methoxyflurane (Penthrox®) is the only volatile analgesic currently available for pre-hospital use.~Methoxyflurane (Penthrox®) is a single-use inhalation non-opioid analgesic for the management of moderate to severe traumatic pain.
