Clinical indicators for traumatic intracranial findings in mild traumatic brain injury patients

Abstract

© 2019 Published by Scientific Scholar on behalf of Surgical Neurology International Background: Mild traumatic brain injury (MTBI), accounting for 80% of traumatic brain injury, is one of the most common conditions seen in emergency departments. Clinical parameters to predict intracranial lesions vary among guidelines. is study intended to find clinical parameters that can predict traumatic intracranial lesions in the setting of a middle-income country. Methods: Data from mild head injury patients admitted to the emergency department from two large hospitals in Chiang Mai, ailand, were prospectively collected from 2013 to 2014. The primary outcome was identifying clinically-important traumatic brain injury (ciTBI), and the secondary outcome was the neurosurgical procedure performed. Ten clinical findings and six predicting factors were analyzed using univariable and multivariable analysis. Results: Among 1164 patients, ciTBI was identified in 244 cases (21.0%). The neurosurgical operation was performed in 57 cases (4.9%). Multivariable analysis showed factors for ciTBI were a diffuse headache, neurological deficits, signs of skull base fracture, Glasgow Coma Scale Score <13–14 after 2 h of observation, wound at the scalp, palpable skull fracture, dangerous mechanism, and vomiting 2 times or more. Loss of consciousness, amnesia, intoxication, and age were not predictors for ciTBI. Conclusion: We found eight indicators to associate with ciTBI after MTBI which can be used to develop further clinical guidelines for computed tomography scans.
