Use of Penthrox in Extra-hospital Traumatology

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. The purpose of this study is to answer the question: Does the use of the inhaled route with Penthrox add value to the treatment of acute traumatic pain in the pre-hospital stage?
