[Effect of logistic and medical emergency resources on fatal outcome of severe trauma].
122 cases of patients who died in sequel of an accident (recruitment period 1993/94, mean ISS 40 +/- 19) in reach of air rescue base Dresden, Germany, were examined. Data were assessed from autopsy protocol and the protocol of the physician who treated on scene. We analyzed the time course of the emergency, the scheduled emergency medical service and the quality of prehospital diagnosis and therapy by the emergency team. The mean response time was 8.1 +/- 5.9 min, the mean distance between EMS bases und incident location 5.9 +/- 5.7 km. In 94.4% of all cases a mobile intensive care unit--with an emergency physician as crew member--was on scene, in 5.6% a paramedic car. Air rescue by helicopter, including an emergency physician, was performed only in 8.7% of all cases although a helicopter was available in 54% of all accidents. Mechanisms of injury were traffic accident (71.4%), fall (14.3), 5.9% accident on building site, shot and stab injuries (5.9%) and burns (1.7%). 82 patients reached the emergency room alive (67.2% mean ISS 37 +/- 18). Only 26% of all patients were transported directly to a level I trauma center. Mean survival time of all 122 patients was 146 +/- 30.4 h. Severe head injury described by autopsy protocol was diagnosed on scene in 82%. Preclinical treatment was:intubation and ventilation (63%), O2 insufflation (17.4%), no specific treatment (19.6%). Severe thoracic trauma was diagnosed in 54%. Preclinical treatment was:intubation and ventilation (64.8%), O2 application (18.8%), no specific treatment (16.2%). Severe thoracic trauma with hemato-pneumothorax (n = 26) was recognized by the emergency physician in 65.6%, specific therapy (application of chest drain) was performed in 7.1%. Preclinical diagnosis rates concerning abdominal trauma were 29% and 27.8% in case of unstable pelvis fracture. Hemorrhagic shock related to these injuries was found in 44.2%, mean resuscitation volume applicated in these cases was 960 +/- 610 ml. Typical faults in diagnosis and treatment were underestimating of severe trunk trauma and non-consistent use of invasive treatment procedures. Primary transport of the severely injured patient to a level I trauma center by helicopter was performed only rarely.
