[The role of computed tomography for minor head injury].

Head trauma is a major health problem which affects young people, especially young males and also causes serious economic losses. Although major head injuries are cause greater morbidity and mortality, minor head injuries are more common presentations to emergency departments. In this study our goal is to determine the prevalence of CT usage in minor, adult head injury patients and determine clinical variables for the use of head CT scans. In our study we retrospectively examined 230 adult head injury patients who were presented to the Dokuz Eylül University Medical School Hospital Emergency Department. We recorded age, gender, symptoms of nausea, vomiting, headache, alcohol use, physical examination findings, history of loss of consciousness prior to presentation, concurrent injuries, and Glasgow Coma Scale (GCS) scores. Head CT ordering and abnormal findings were correlated with the above clinical variables. We ascertained that all variables affected the ordering of CT scans except age, gender and alcohol use. The prevalence of abnormal head CT in all patients were 21.7%. We found that GCS is only one clinical variability of which statistically significant relationship to acquaint abnormal CT findings.
