[Emergency room patients]

Abstract

The aim of the study was to examine the predictive value of CT for severe intracranial lesions of mild (GCS 15-13) and moderate (12-9) head injuries. Further,we examined the possibility of predicting these lesions by various variables/factors. Data were collected prospectively from the trauma registry of the DGU (Deutsche Gesellschaft für Unfallchirurgie). Patients with a GCS score from 15-13 and from 12-9 were included in this study and examined for intracranial lesions (AIS(head) 3-6). Over a time period from 1993 to 1999, 1778 patients with mild head injury and 235 patients with moderate head injury were analyzed. Severe intracranial lesions were suffered by 18.6% of the patients with mild head injury and 50.4% of the patients with moderate head injuries. Of the predictive variables, heart rate,patients' age,and primary assessment by the emergency physician showed a strong correlation with the later observed intracranial lesions.

In conclusion: (1) independently of the initially good GCS, a high percentage of patients suffered from severe intracranial lesions and (2) besides the GCS only the patients'age and primary assessment by the emergency physician were useful for identifying patients at risk for an intracranial lesion.
