Modified CT imaging scale in assessment of prognosis of comatose patients with severe traumatic brain injury

Abstract

Objective To explore the application of modified CT imaging scale in the assessment of prognosis of comatose patients with severe traumatic brain injury. Methods Retrospective analysis was performed on the clinical data of 90 comatose patients with severe traumatic brain injury; according to the prognosis,they were divided into conscious group (n=47) and coma group (n=43).The modified CT imaging scale was used to analyze the relationship between these CT imaging data and prognosis,and the relationship between these CT imaging data and severity of illness. Results The scores of CT imaging scale in comatose patients were significantly higher than those in conscious patients (P＜0.05). Patients with 3-5 scores in GCS enjoyed higher scores of CT imaging scale as compared with those with 6-8 scores (P＜0.05).The scores of modified CT imaging scale and the GCS scores in these 90 patients showed negative correlation (Spearman's correlation coefficient:r=-0.79,P=0.000). Conclusion The modified CT imaging scale is helpful in assessing the prognosis and guiding the clinical treatment of comatose patients with severe traumatic brain injury.
