Use of Penthrox in Extra-hospital Traumatology
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?

 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?
