Abstract:
Objective:To investigate the effect of abnormal D-dimer level on the prognosis of patients with frontal lobe injury, and to provide a new idea for clinical diagnosis, treatment and prognosis evaluation of frontal lobe injury.Methods:A retrospective analysis was performed on 71 patients with traumatic brain injury (TBI) who were admitted to the Surgical Care Unit of the First Affiliated Hospital of Zhejiang University School of Medicine from November 1, 2020 to February 1, 2021. According to whether TBI involved in the frontal lobe, the patients were divided into the experimental group ( n = 44) and the control group ( n = 27). Clinical data including sex, age, body mass index (BMI), length of hospital stay, ISS trauma score, GCS coma score, qSOFA score, GOS prognostic score and coagulation index test results within 24 h of admission of the two groups were recorded, and the difference of each index between the two groups was compared. Results:① D-dimer levels were significantly higher in the experimental group than in the control group ( P<0.01); ② The incidence of complications in the experimental group was 40.9%, of which the incidence of lower limb vein thrombosis was 18.2%, and the incidence of complications in the control group was 18.5%, of which the incidence of lower limb vein thrombosis was 3.7%; there were statistical differences between the two groups ( P<0.05); ③ The average hospital stay of patients was 10.96 days in the control group, and 15.50 days in the experimental group with a statistically significant difference between the two groups ( P<0.05); ④ The 28-day mortality rate of patients in the experimental group was 18.2% and 7.4% in the control group. There was no significant difference in 28-day mortality between the two groups ( P>0.05); ⑤ The level of D-dimer was negatively correlated with GOS prognostic score in patients with frontal lobe injury ( r=-0.501, P<0.01). Conclusions:Patients with frontal lobe injury have increased D-dimer levels, increased incidence of complications, and longer hospital stay. There is a significant negative correlation between D-dimer level and prognosis in patients with frontal lobe injury. D-dimer can be used as a sensitive indicator to evaluate the prognosis of patients with frontal lobe injury. The higher the D-dimer level, the worse the prognosis of patients.
