Brief summary

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?

Detailed description

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. This treatment has been used in New Zealand and Canada for over 20 years for the management of acute pain in adults and children. It was granted marketing authorization in Europe in 2016 and has been marketed in France since 2017. The purpose of this study is: * To study the efficacy and safety of Penthrox, administrated at the beginning of the management of the traumatized adult patient. * Assess the comfort of patients and caregivers * 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?

Interventions
