HEMS paramedic intubation success

All medical out of hospital cardiac arrests attended by the Warwickshire and Northamptonshire Air Ambulance (WNAA) over a 64-month period were reviewed. There were no significant differences in self-reported intubation failure rate, morbidity or clinical outcome between doctor-led and paramedic-led cases. The authors conclude that experienced paramedics regularly operating with physicians have a low tracheal intubation failure rate at out of hospital cardiac arrests, whether practicing independently or as part of a doctor-led team, and that this is likely due to increased and regular clinical exposure.
