Diagnostic and predictive value of white blood cell count and erythrocyte sedimentation rate and coagulation tests in patients with blunt head trauma

Abstract

The aim of this study was to evaluate the diagnostic and predictive value of white blood cell count and erythrocyte sedimentation rate and coagulation tests in the outcome of patients with blunt head trauma. Materials and Methods: All patients referred to the Emergency Department of Tabriz Imam Reza Hospital during the first six months of the year 2017, with a complaint of blunt head trauma of type DAI, were enrolled in a complete and sequential study. Patients were divided into two groups with good prognosis and poor prognosis and their association with leukocytosis status, and other paraclinical factors at baseline. Results: The final outcome in high consciousness group was 13.3% need for intubation, 26.7% need for surgery, 50% improvement without complications and 10% mortality. In the low consciousness group, 16.7% required intubation, 20.0% required surgery, 10% had no complications, and 53.3% mortality. The significance level of the chi-square test was 0.001, indicating a significant difference between the two groups in terms of final outcome. Independent t-test results showed that the WBC and ESR values in the low consciousness group were significantly higher than the high consciousness group. But the INR in the high consciousness group was significantly higher than the low consciousness group (p <0.05).
