Clinical value of thrombus elasto graph in guiding clinical transfusion

Abstract

Objective To explore the guiding value of thrombus elasto graph in clinical blood transfusion. Methods From March 2016 to February 2018, 98 patients who were given blood products in the People's Hospital of Shanxi Province were selected.The patients were divided into the observation group and the control group by the random stratification method, with 49 cases in each group.The observation group used thrombus elastograph to guide blood transfusion, while the control group used conventional coagulation indicators to guide blood transfusion.The amount of blood products and the clinical outcome of the two groups were compared, and the correlation between the parameters related to the thrombus map (R, MA, Angle) and the traditional blood coagulation index were analyzed. Results The blood loss during operation in the observation group was (955.3±211.3)mL, which was significantly less than (1 145.8±201.2)mL in the control group, and the difference was statistically significant (t=4.570, P<0.05). , The use of suspended red cells, Hb, PLT and fresh frozen plasma in the observation group were (4.25±1.07)U, (2.32±1.08)g, (2.14±0.58)U, (217.5±21.3)mL, respectively, which were significantly less than those in the control group (t=9.074, 7.017, 10.238, 51.761, all P<0.05). APTT and PT were positively correlated with R (r=0.46, 0.35, all P<0.05). FIB was positively correlated with MA (r=0.37, P<0.05). PLT was positively correlated with Angle angle and MA (r=0.51, 0.71, all P<0.05). Conclusion Compared with the conventional coagulation index, the thrombus map is of guiding value for the rational use of blood products for the patients who need the blood transfusion.It can help to reduce the amount of blood transfusion, and it is worth to be popularized in clinical practice.
