[Prehospital ultrasound].

Danish anaesthesiologists use ultrasound (US) to examine and treat acutely ill or traumatized patients in the emergency room, operating theatre and intensive care unit. They are also involved in pre-hospital care where US may theoretically be beneficial for both diagnostic and therapeutic purposes. The literature concerning the potential use of emergency US in the pre-hospital setting is evaluated. Evidence from both Europe and the USA indicates that pre-hospital US improves diagnosis and visitation of acutely ill or traumatized patients.
