[Multiple trauma: preclinical needs, transportation, time sequences].

Compared to the magnitude of the trauma problem few precise data exist on prehospital care of trauma patients. The aim of the study was the collection and careful evaluation of prehospital data on trauma patients concerning time sequences, patients' status and prehospital interventions. From 1. 1. 1987 to 31. 12. 1990 all 49,045 prehospital emergencies in Cologne were prospectively registered. 8792 trauma patients were treated by an emergency physician in the field. 9.5% were severely injured, defined by a trauma score less than or equal to 12. 9.9% of the trauma patients were intubated, 54.9% received an i.v. line, and 20.6% were triaged to a trauma center. Our data form a valid base for analysis of the effectiveness of prehospital trauma care.
