AbstractThe frequency of minor closed head injuries is high. These injuries may be complicated by the development of life-threatening intracranial hematomas. A well-defined selection criteria for admission must be proposed to guarantee an efficacious observation. In our series of 489 hospitalized patients with a GCS of 15 when seen in the emergency room: 4 patients required evacuation of an intracranial hematoma, 11 revision of a depressed skull fracture or a compound fracture of base of the anterior fossa. Using the existence of a skull fracture as a selection for admission, a strategy proposed by Jennett and colleagues, it would have been possible to reduce the number of patients hospitalized by 70% without missing a patient who developed an intracranial hematoma. Following these criteria no intracranial hematoma would be missed in our patients with a GCS of 15. We suggest that the use of plain x-rays to identify skull fractures and subsequent hospitalization prevents missing an intracranial hematoma. Those patients with diminished levels of consciousness of focal neurologic deficits require admission irrespective of skull fractures.
