Objective: To investigate the relationship between TEG index and routine coagulation test in patients with community acquired pneumonia in Emergency Department. 

Methods: Clinical data of 246 patients with community acquired pneumonia in Emergency Department were retrospectively chosen in the period from January 2017 to December 2019. The blood coagulation and TEG indexes in all patients were tested in the laboratory and the correlation between them were analyzed by Pearson method. 

Results: There were no correlation between PT, Fib with R time in TEG index (r = 0.17, P = 0.10). There were significant correlation between R time in TEG index and APTT (r = 0.67, P = 0.00). There were significant correlation between K value in TEG index and Fib (r = -0.31, P = 0.00). There were significant correlation between α-Angle in TEG index and Fib (r = 0.48, P = 0.00). There was no correlation between MA in TEG index and Fib (r = 0.15, P = 0.12). There were significant correlation between K value in TEG index and PLT (r = -0.44, P = 0.00). There were significant correlation between α-Angle in TEG index and PLT (r = 0.51, P = 0.00). There were no correlation between MA value and PLT in TEG index (r = 0.10, P = 0.44). There were no correlation between R value, K value, α-Angle, MA value with D-D (r = 0.05, 0.28, 0.33, 0.19, P = 0.75, 0.18, 0.21, 0.35), neither with FDP (r = 0.60, 0.22, 0.37, 0.29, P = 0.66, 0.10, 0.18, 0.31). 

Conclusion: There were the correlation between TEG detection indexes and four items of routine coagulation, but they could not replace each other.
