Factors Affecting Abnormal CT Scan in Mild Traumatic Brain Injury – High-Risk Patients
Keywords:
head injury; traumatic brain injury; cerebral concussion; intracranial hemorrhageAbstract
Background and Objective: Traumatic brain injury is one of the most significant problems worldwide. Major causes of head injury are caused by traffic accidents and fallings. In mild traumatic brain injury, consider that there are risk factors for abnormalities in the brain. However, there is a lack of study in risk factors for neurosurgical intervention related to abnormal CT findings in Thai people.
Method: Retrospective descriptive study in the patients diagnosed mild traumatic injury (GCS 13-15), with high risk for abnormalities in CT scan. The outcome of the study is to admeasure the ratio of abnormal CT findings and to determine factors that affected abnormal CT findings.
Results: There were 117 mild traumatic brain injury – high-risk patients performed a CT scan. Of those, 41 patients (35%) had abnormal CT findings. Two significant factors affecting abnormal CT findings; GCS 13-14 after observation and signs of open/base of skull fractures with a number of 5 (p£0.011) and 5 (p=0.037), respectively.
Conclusion: Open skull or base of skull fracture and GCS of 13-14 observation were the most two strongest predictors for abnormal CT scan in mild traumatic brain injury – high-risk patients.
