Risk of complications using a sedation protocol for aeromedical retrieval of acutely unwell mental health patients: a retrospective cohort study in Outback Australia

A protocolised approach to sedation of AMH patients undergoing aeromedical retrieval, including the use of ketamine sedation, was associated with fewer complications overall, fewer severe complications and no episodes of treatment failure or need for intubation. Our findings suggest that the use of midazolam and/or intubation in this cohort is associated with a higher risk of complications, and ketamine presents a safer alternative.
