[Prehospital treatment of severely injured patients in the field: an update].

Life or extremity threatening injuries have to be diagnosed and treated rapidly by emergency physicians during prehospital care for severely injured patients. The cooperation with other rescue services, the fire brigade and the police must be coordinated and early transportation has to be organized. Rapid sequence intubation by trained personnel for correct indications, such as head injury or severe chest trauma is recommended as well as prehospital chest tube placement in cases of severe or penetrating thoracic injury. Crystalloids and colloidal solutions remain the first choice for intravenous volume replacement. The amount of fluid depends on the individual response, such as palpable peripheral and central pulse for blunt or penetrating trauma. Ultrasound or near infrared spectroscopy could not be routinely implemented for extended prehospital diagnostic procedures. Transportation to the closest appropriate hospital has to be accomplished as early as possible. Helicopters show positive outcomes if the destination is a level I trauma center, even if secondary alarm calls or more extensive measures prolong the prehospital interval.
