Effects of thromboelastography guided blood transfusion on blood potassium, coagulation parameters and prognosis in patients with post-traumatic massive hemorrhage / 中国医师进修杂志

ABSTRACT

Objective:Analyze the influence of blood transfusion therapy under the guidance of thromboelastography on the blood potassium and coagulation indicators and prognosis of patients with post-traumatic hemorrhage.Methods:The clinical data of 73 patients with post-traumatic hemorrhage in Liyang People′s Hospital from March 2018 to February 2021 were retrospectively analyzed. Among them, TEG blood transfusion guidance group (group A) and conventional coagulation indicator guidance group (group B) were divided according to whether TEG test was performed. Repeated measurement analysis of variance and post LSD- t test were used to observe serum potassium, coagulation indexes and prognosis of 2 groups at each time point. Results:The amount of various drugs used in group A was significantly lower than that in group B ( P<0.05). Comparison of serum potassium levels between the two groups before transfusion (3.94 ± 0.85) mmol/L vs. (3.98 ± 0.71) mmol/L; and on the first day after transfusion (4.33 ± 0.48) mmol/L vs. (4.57 ± 0.73) mmol/L, there were statistically significant ( P<0.05); on day one. day two and day three after blood transfusion, the indexes of PT and APTT in group A were significantly lower than those in group B PT (14.30 ± 1.43) s vs. (16.25 ± 1.74) s, (14.41 ± 1.55) s vs. (16.27 ± 1.48) s, (14.73 ± 1.50) s vs. (16.30 ± 1.45) s; APTT (32.3 ± 3.6) s vs. (36.7 ± 3.5) s, (32.6 ± 3.4) s vs. (36.8 ± 3.6) s, (32.2 ± 3.2) s vs. (36.3 ± 3.3) s; the above indexes of the two groups before treatment were significantly higher than those at each time point after treatment ( P<0.05). The total effective rate of hemostasis in group A was higher than that in group B 97.37%(37/38) vs. 80.00%(28/35), P<0.05. Conclusions:Patients with post-traumatic hemorrhage can be recovered by blood transfusion under the guidance of thromboelastography, and the disorder of blood coagulation indicators can be restored, and at the same time, it has a better hemostatic effect.
