Description of intervention(s) / exposure
Patients enrolled in the study have been prescribed no less than four (4) doses of methoxyflurane for the treatment of acute pain associated with the management of burns or wound injuries.

Safety data, including adverse event data, will be collected retrospectively from medical records completed as part of in-patient management, with data being from clinical notes and laboratory assessments entered into medical records from the time of each methoxyflurane administration up to 24 hours from each dose.

Data relating to the safety of methoxyflurane will be collected for up to 28 days from the first dose of methoxyflurane to determine the type, occurrence and severity of adverse events as recorded in the medical records that may indicate a possible relationship with methoxyflurane use.
An additional evaluation period of 28-days from the last dose of methoxyflurane is intended to collect data specific to adverse events of special interest.

Intervention code [1] 312857 0
Diagnosis / Prognosis
Comparator / control treatment
Patients admitted to approved study sites who have been prescribed no less than four (4) doses of analgesics (nitrous oxide or short acting opioids) for the treatment of acute pain.

Data from up to 250 patients will be retrospectively collected from medical records at approved study sites.
