Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 10
Abstract
Objective To investigate the correlation between D-dimer, serum potassium and thromboelastography parameters and progressive hemorrhagic injury (PHI) after brain injury. Methods The data of 209 patients with traumatic brain injury (TBI) in our hospital from January 2018 to May 2021 were collected and analyzed. The patients were divided into PHI group (161 cases) and non-PHI group (48 cases) according to CT scan whether the total bleeding lesions had increased by 25%. Univariate analysis and multivariate Logistic regression were used to analyze the risk factors of PHI, and receiver operating curve (ROC) was used to analyze the predictive value of D-dimer, serum potassium and thromboelastography (TEG) parameters used alone and in combination. Results PHI occurred in 48 (23.0 %) out of 209 TBI patients. In univariate analysis, there were statistically significant differences in GCS score, age, light emission, systolic blood pressure, serum potassium, blood calcium, blood glucose, R value, PT, APTT, INR, D-dimer, arachnoid hemorrhage, subdural hematoma, cerebral contusion and midline location between the two groups (P<0.05). Five independent risk factors were determined by multivariate Logistic analysis (P<0.05): D-dimer ≥3.52 μg/mL, serum potassium <3.70 mmol/L, R value ≥5.65 min, subdural hematoma and cerebral contusion. PHI model was constructed according to independent risk factors, and the maximum area under the curve (AUC) of D-dimer plus serum potassium plus R value plus subdural hematoma plus cerebral contusion was 0.889 9. Conclusion D-dimer ≥3.52 μg/mL, serum potassium <3.70 mmol/L, R value ≥5.65 min, subdural hematoma and cerebral contusion are significant influences for PHI occurrance in TBI patients.
