STUDY OBJECTIVES: To identify the value of symptoms in head trauma patients with alert mental status requiring a head CT scan.
A retrospective study was performed at an emergency center over 8 months period. Patients(age > or = 7) were enrolled if they presented with a Glasgow Coma Scale score of 15 and underwent head CT after head trauma. The symptoms and signs were recorded in the entry forms prior to head CT The symptoms found in the patients with normal CT were compared with those in abnormal CT showing intracranial injuries.
Among the 168 patients, traumatic intracranial abnormality was identified in 34(20.2%) by CT. Skull fracture was idendified in 8(4.8%) in normal CT, 17(10.1%) in abnormal CT group by simple X-ray and CT. In the normal CT group without skull fracture, 65(52.0%) had headache, 61(48.8%) had loss of consciousness( LOC), 43(34.4%) had vomiting, 24(19.2%) had nausea, 7(5.6%) had dizziness. In the abnormal CT group without skull fracture, 14(77.8%) had heacache, 9(50.0%) had LOC, 9(50.0%) had vomiting, 2(11.1%) had nausea, 2(11.1%) had dizziness. The patients with headache were significantly more common in the abnormal CT group.
A head CT is required in alert head trauma patients with any symptoms and signs of intracranial injuries, especially with headache.
