Effects of massive blood transfusion on serum electrolyte balance and inflammatory factor levels in patients with severe trauma / 中国基层医药

ABSTRACT

Objective:To investigate the effects of massive blood transfusion on serum electrolyte balance and serum levels of C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in patients with severe trauma.Methods:A total of 83 patients with severe trauma who received treatment in Eastern District of LiHuili Hospital, Ningbo Medical Center between July 2019 and December 2020 were included in this study. All of them underwent blood transfusion. They were divided into massive blood transfusion group ( n = 29) and general blood transfusion group ( n = 54) according to the volume of blood transfused. Changes in coagulation function, electrolyte, liver-kidney function and inflammatory factor levels pre- and post-blood transfusion were compared between massive blood transfusion and general blood transfusion groups. Results:At 1 day after blood transfusion, activated partial thromboplastin time (APTT) and prothrombin time (PT) in the massive blood transfusion group were (45.64 ± 2.78) seconds and (17.71 ± 2.08) seconds, respectively, which were significantly longer than those in the general blood transfusion group [(41.02 ± 2.80) seconds, (15.35 ± 1.72) seconds, t = 5.53, 7.18, P < 0.05). At 1 day after blood transfusion, levels of tumor necrosis factor-α, interleukin-6 and C-reaction protein in the massive blood transfusion group were (1.84 ± 0.32) μg/L, (113.72 ± 13.34) ng/L, (28.94 ± 4.22) mg/L, respectively, which were significantly increased compared with those measured before blood transfusion [(1.28 ± 0.29) μg/L, (95.18 ± 10.64) ng/L, (16.48 ± 3.37) mg/L, t = 6.98, 5.85, 12.42, all P < 0.05]. Levels of tumor necrosis factor-α, interleukin-6 and C-reaction protein in the general blood transfusion group were (1.34 ± 0.27) μg/L, (98.54 ± 9.62) ng/L, (20.05 ± 3.30) mg/L, respectively at 1 day after blood transfusion, which were significantly increased compared with those measured before blood transfusion [(1.23 ± 0.26) μg/L, (94.22 ± 8.82) ng/L, (16.16 ± 3.39) mg/L, t = 2.15, 2.43, 6.04, all P < 0.05]. At 1 day after blood transfusion, serum levels of tumor necrosis factor-α and C-reaction protein in the massive blood transfusion group were significantly higher than those in the general blood transfusion group ( t = 7.53, 10.59, both P < 0.05). At 1 day after blood transfusion, serum levels of K + and Ca 2+ in the massive blood transfusion group were (3.56 ± 0.54) mmol/L and (1.87 ± 0.28) mmol/L, respectively, which were significantly lower than those in the general blood transfusion group [(4.27 ± 0.34) mmol/L, (2.26 ± 0.24) mmol/L, t = 7.34, 6.65, both P < 0.05]. Serum levels of alanine aminotransferase and aspartate aminotransferase in the massive blood transfusion group were (52.46 ± 20.27) U/L, (82.37 ± 31.15) U/L, respectively, which were significantly higher than those in the general blood transfusion group [(37.57 ± 10.31) U/L, (49.35 ± 10.14) U/L, t = 4.44, 7.14, both P < 0.05)]. The incidence of abnormal liver function in the massive blood transfusion group was significantly higher than that in the general blood transfusion group [62.07% (18/29) vs. 29.63% (16/54), χ2 = 10.13, P < 0.05)]. Conclusion:The internal environment of patients with severe trauma will change after massive blood transfusion. Their coagulation function, inflammatory factors, liver function and electrolyte balance should be monitored in time.
