Correlation between the Glasgow Coma Scale and cranial computed tomography imaging findings in the patients with mild head injury at Phatthalung hospital
Keywords:Mild head injury, cranial CT scan, Glasgow coma scale
Objective : To assess the correlation between the Glasgow Coma Scale (GCS) and cranial computed tomography (CT) imaging findings in the patients with mild head injury.
Method : A retrospective study was performed in 240 patients with mild head injury who were estimated the outcomes of head injury by Glasgow Coma Scale (13-15) and submitted to cranial computed tomographyat first 24 hours post trauma in Phatthalung hospital.
Result : The overall male to female ratio was 1.5:1. The range of the most common age is11-20 years. The most common causes were motorcycle accident (51.3%) and fall (27.9%). Abnormal CT findings were seen in 68 patients (28.3%), and were seen in the patients with GCS 13 = 62.5%, 14 = 39.3% and 15 = 25.5%. The most common abnormal intracranial CT findings were subdural hematoma (8.3%) and hemorrhagic contusion (7.9%).The most common related symptom with abnormal CT findings were posttraumatic amnesia (31.1%) and headache (31.0%).
Conclusion : Low Glasgow Coma Scales were considered as a severity risk factor in association with greater number of abnormal CT finding.
