[Cranial traumas in the city of Ravenna: a prospective study of patients who recovered].

Abstract

A prospective study of head injury patients was carried out in the city of Ravenna in 1984. A complete record was completed for all patients admitted for hospital care. More than 50 clinical and diagnostic variables were evaluated to investigate risk factors on patients admitted to a Non-Neurosurgical Unit with CT facilities. Our report deals with 578 cases and shows some interesting findings: The mortality in the entire trauma-group was 42 cases; 35 (83%) of these died immediately after the accident or while being transported to the hospital. The number of patients hospitalized (42%) was much higher than that in previous reports concerning hospital admission of head injury patients. 9 cases were sent from the First Aid to Regional Neurosurgical Centre (Bellaria Hospital, Bologna). Among the other patients admitted to the Non-Neurosurgical Centre, 12 showed cerebral lesions on the CT (1 extradural haematoma). Risk factors were evaluated by comparing EEG, skull fractures and poor clinical condition with the presence of cerebral lesions. Our data show a peculiar situation here in Italy: a large number of hospital admissions for minor head injuries, of whom relatively few patients are at risk of intracranial post-traumatic haematoma.
