Abstract:
【Objective】 To explore the effects of intraoperative autologous blood(ABT) transfusion on thrombelastography(TEG) in patients underwent neurosurgical procedures. 【Methods】 96 patients (49 males and 47 females) aged 15~79 years who received neurosurgical procedures in our hospital from November 2018 to November 2020 were retrospectively analyzed and divided into autologous blood transfusion group(Group A, n=52)and allogeneic blood transfusion group(Group B, n=44)according to different blood transfusion strategy in operation. The red blood transfusion status, hemoglobin (Hb), hematocrit (Hct), platelet (Plt), fibrinogen(Fib), prothrombin time (PT), activated partial thromboplastin time(APTT), and TEG parameters [activated clotting time(ACT), coagulation time (K), angle rate of clot formation(Angle), maximum amplitude(MA)] before and 1 day after surgery were compared between the two groups. 【Results】 The amount of average blood transfusion didn′t differ significantly by groups (P>0.05). The incidence of extra allogeneic blood transfusion was 17.3%(9/52) in group A, and the amount of average allogeneic blood transfusion in group A was significantly lower than that in group B(333.3±81.7 vs 639.8±258.2, P<0.05). Before operation, the differences in Hb, Hct, Plt, Fib, PT, APTT, ACT, K, MA and Angle levels between the 2 groups were not statistically significant (P>0.05). One day after operation, the Hb(g/L) (109.4±15.8 vs 97.0±15.1), Hct (%) (32.0±4.3 vs 28.3±6.1), Plt(×109/L)(154.2±54.2 vs 120.7±41.6), Fib(g/L)(2.2±0.5 vs 1.6±0.6), MA(mm)(65.0±7.2 vs 60.7±8.7) and Angle levels(deg)(69.1±5.2 vs 62.6±9.8) in group A were significantly higher than those in group B(P<0.05), and the PT(s)(11.9±1.5 vs 12.8±0.9), APTT(s)(27.4±3.3 vs 30.4±5.4), ACT(s)(111.0±14.9 vs 119.1±12.3) and K levels(min)(87.2±25.7 vs 106.4±28.0) in group A were significantly lower than those in group B (P<0.05). 【Conclusion】 Intraoperative ABT in patients underwent neurosurgical procedures can reduce allogeneic blood transfusion, has less effect on coagulation function and TEG, and is safe and effective.
