Abstract: Objective To explore the risk factors of early traumatic coagulation (TIC) in elderly patients with chest trauma. Methods The data of 113 elderly patients with chest trauma admitted in a hospital from January 2016 to January 2022 were retrospectively analyzed.Patients were divided into TIC group and non-TIC group according to whether they had early TIC.The risk factors of early TIC in elderly patients with thoracic trauma were analyzed by single factor and multi factor methods.Analysis of the predictive value of early TIC in elderly patients with thoracic trauma using multifactor model. Result Of all the patients included in the study,27 were determined as TIC,and the rest 86 were non-TIC.The results of univariate analysis showed that there were statistically significant differences in the data of shock index,platelet count at admission and plasma fibrinogen at admission between patients in TIC group and non-TIC group (P＜0.05).Multivariate analysis showed that the shock index at admission,platelet count at admission,and plasma fibrin at admission were all independent influencing factors of early TIC in elderly patients with chest trauma (all P＜0.05).The P value of multivariate model and independent variables predict the early TIC of elderly patients with chest trauma.The Yoden index is 36.95%,42.89%,75.58% and 78.85% respectively.Conclusion The shock index,platelet count and plasma fibrin at the time of admission can affect the early occurrence of TIC in elderly patients with chest trauma.
