BackgroundEmergency ultrasound as part of the provision of emergency medical services using mobile devices offers great benefits regarding to some important questions related to the management of critically ill and injured patients in the prehospital situation where diagnostic resources are limited. The aim of this study is to determine whether the comprehensive introduction of prehospital emergency ultrasound examinations into a German Emergency Medical Services ("rescue services") area is both feasible and beneficial for patients.MethodsAll emergency physicians at a rural emergency physician base were trained in emergency ultrasound scanning techniques (FAST, FEEL, 14 h of instruction), followed by regular weekly training sessions of approximately 30 min. Over a period of 12 months, prehospital ultrasound examinations performed during emergency physician callouts at this base were documented and analysed.ResultsA total of 87 emergency ultrasound examinations were performed during 1343 callouts. Among these, focussed assessment with sonography for trauma (FAST) was performed in 35 patients (40.2%) and focused echocardiography in emergency life support (FEEL) in 41 patients (47.1%). In 11 patients (12.6%), ultrasound scans were performed for other indications (e. g. to rule out urinary tract obstruction in a case of flank pain). One trauma patient's life was saved by the decision to transport him to the nearest hospital and once there directly to the operating room, based on the ultrasound finding of significant free intra-abdominal fluid (ruptured spleen and liver).ConclusionPrehospital emergency ultrasound can be introduced into an emergency medical service area as a diagnostic modality that provides benefits to patients. Emergency physicians have to be specifically trained and to participate in continuous education activities. Especially in rural areas with longer transport routes and journey times, the early diagnosis of for example massive intra-abdominal bleeding is critical for the patient's prognosis.
