ABSTRACT
Objective To explore the correlation between the glucose variability and the severity of acute isolated traumatic brain injury(TBI). Method According to the inclusion/exclusion criteria,a total of 125 cases of acute isolated TBI admitted in Department of Neurosurgery of China Medical University from July 2012 to June 2015 were included. According to Glasgow coma scale(GSC),the patients were divided into five groups including control(GCS 15),mild(GCS 13?14),moderate(GCS 9?12),severe(GCS 6?8),and extra?severe(GCS 3?5)groups. Blood glucose control(including relief of the stress and the application of insulin)were carried out immediately. The average,standard deviation,and variation co?efficient of blood glucose of all groups were recorded at admission,48 hours and 3?7 days after hospitalization. The clinical records and glycemic in?dex were compared among different groups and during different periods,so as to analyze the relationship of the variability of glucose and the duration of hyperglycemia with the severity of TBI and the effects of glycemic intensive care management. Results The results of Kruskal Wallis test and Mann?Whitney Utest showed that the average,standard deviation,and variation coefficient of glucose in the extra?severe group and the severe group were statistically higher than those in the control group(P1). Conclusion The glucose variability in acute isolated TBI patients could be considered as the index of the severity of TBI.
