IL6 and hematoma: The level of the proinflammatory cytokine interleukin 6 (IL-6) [(58.6 ± 14.6) pg/ml vs. (3365.8 ± 863.7) pg/ml, p = 0.00] and the content of D-dimer [(2044.5 ± 218.3) ng/ml vs. (1244236.8 ± 152545.6) ng/ml, p = 0.00], which reflects the local severity of fibrinolysis in the hematoma, were significantly higher than those in the peripheral venous blood (Table 3).
