ABSTRACT
OBJECTIVES@#The number of gestational women has been increased in recent years, resulting in more adverse pregnancy outcomes. It is crucial to assess the coagulation function of pregnant women and to intervene in a timely manner. This study aims to analyze the influencing factors on thrombelastography (TEG) and explore the evaluation of TEG for gestational women.@*METHODS@#A retrospective study was conducted on 449 pregnant women who were hospitalized in the obstetrics department in Xiangya Hospital of Central South University from 2018 to 2020. We compared the changes on the TEG parameters among normal pregnant women between different age groups, different ingravidation groups, and different stages of pregnancy groups. The influence on TEG of hypertensive disorders in pregnancy (HDP) and gestational diabetes mellitus (GDM) as well as two diseases synchronization was explored.@*RESULTS@#Compared with the normal second trimester women, the R values and K values of TEG were increased, and α angle, CI values and LY30 values were decreased in third trimester women (all P<0.05). Compared with normal group, the R values and CI values of TEG of the HDP group have significant difference (both P<0.05). There were no significant difference of TEG between the GDM group, the HDP combined with GDM group and the normal group (all P>0.05). Multiple linear regression analysis showed that the influencing factors for R value in TEG were weeks of gestation (P<0.001) and mode of conception (P<0.05), for α angle was weeks of gestation (P<0.05), for MA value was mode of conception (P<0.05), and for CI value was weeks of gestation (P<0.05). The analysis of correlation between TEG with platelet (PLT) and coagulation routines represented that there was a correlation between TEG R values and activated partial thromboplastin time (APTT) (P<0.01), and negative correlation between TEG CI values and APTT (P<0.05). There was a negative correlation between TEG K values and FIB (P<0.05). The correlation of α angle (P<0.05), MA values (P<0.01) and CI values (P<0.05) with FIB were positive respectively.@*CONCLUSIONS@#The TEG parameters of 3 stages of pregnancy were different. The different ingravidation approach has effect on TEG. The TEG parameters were consistent with conventional coagulation indicators. The TEG can be used to screen the coagulation status of gestational women, recognize the abnormalities of coagulation and prevent the severe complication timely.

【Objective】 To explore the effects of acute normovolemic hemodilution (ANH) combined with intraoperative recycled autotransfusion on blood transfusion volume and coagulation function in elderly patients undergoing cardiac surgery. 【Methods】 A total of 94 elderly patients undergoing cardiac surgery in the hospital were enrolled and randomly divided into observation group (n=47) and control group (n=47) between March 2020 and March 2022. The observation group was given ANH combined with intraoperative recycled autotransfusion, while control group was given routine allogeneic transfusion. The blood transfusion volume, oxygenation status, immune function, inflammatory indexes and adverse reactions in the two groups were compared. 【Results】 The banked blood transfusion volume was less in observation group than control group [(1.73±0.43) U vs (5.71±1.71) U, P<0.05]. At 6 h after surgery, blood oxygen saturation (SvO2) level was higher [(74.59±7.20) % vs (67.22±6.19) %], while oxygen uptake rate (ERO2) level was lower[(0.29±0.06) % vs (0.34±0.05) %] in observation group than control group (P<0.05). At day 1 after surgery, levels of CD3+, CD4+, CD4+ /CD8+ and natural killer cells (NK) were higher [(65.11±5.14) %, (46.93±5.17) %, (1.86±0.30), (8.35±1.23) % vs (57.45±7.24) %, (43.58±4.85) %, (1.47±0.36)%, (7.34±1.38) %], while CD8+ was lower [(25.17±4.01) % vs (30.39±5.06) %] in observation group than control group (P<0.05). At day 1 after surgery, levels of serum interleukin 6/8 (IL-6/8) and tumor necrosis factor-α (TNF-α) were lower in observation group than control group [(104.51±12.55) ng/L vs (125.81±14.96) ng/L, (351.42±52.86) ng/L vs (394.27±55.78) ng/L, (254.93±49.94) ng/L vs (323.60±52.63) ng/L, P<0.05]. The incidence of adverse reactions was lower in observation group than control group (4.26% vs 17.02%), P<0.05. 【Conclusion】 Recycled autotransfusion can reduce allogeneic transfusion volume in elderly patients undergoing cardiac surgery. There is no difference in the effects on blood routine or coagulation function between recycled autotransfusion and allogeneic transfusion. Compared with allogeneic transfusion, recycled autotransfusion can significantly improve oxygenation status, relieve immunosuppression and inflammation response, and reduce the risk of adverse reactions.
ABSTRACT
【Objective】 To explore the effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage patients. 【Methods】 A study on postpartum hemorrhage patients undergoing cesarean section in the Third Affiliated Hospital of Guangxi Medical University form September 2016 to May 2022 was conducted retrospectively. A total of 137 patients were enrolled and divided into experimental group (n=70) and control group (n=67) according to whether intraoperative cell salvage was used during operation. The blood loss, proportion and volume of allogeneic red blood cells (RBCs) and coagulation component transfusion, hemoglobin (Hb) level, coagulation function, electrolyte, the incidence of complications, proportion of ICU admission, ICU stay and in-hospital stay were compared between the two groups. 【Results】 The proportion of patients receiving allogeneic RBCs in the experimental group and in the control group was 31.4% vs 100.0% (P0.05). 【Conclusion】 This study demonstrated that intraoperative cell salvage could reduce the requirement for allogeneic RBCs without compromising coagulation function in postpartum hemorrhage patients undergoing cesarean section, but the changes of calcium need to be concerned after transfusion.
ABSTRACT
【Objective】 To investigate the effects of recombinant human coagulation factor Ⅶa combined with Bakri balloon compression on oxidative stress and coagulation in patients with refractory postpartum hemorrhage. 【Methods】 Prospectively, 80 patients with refractory postpartum hemorrhage in Chengdu Fifth People′s Hospital from June 2019 to June 2022 were selected and grouped according to the random number table method. The control group (n=40) was treated with Bakri balloon compression, and the observation group (n=40) was treated with recombinant human coagulation factor Ⅶa combined with Bakri balloon compression. The bleeding-related indexes and adverse effects were observed in both groups, and the prenatal and 24 h postpartum oxidative stress, coagulation function and inflammatory factors were compared between the two groups. 【Results】 The blood loss in the observation group and the control group was (683.96±146.52) vs(796.63±152.41)mL during operation, (812.46±161.53) vs(965.39±166.22)mL in 2 h after delivery, (899.53±178.74) vs(1 084.31±203.67)mL in 24 h after delivery, and the transfusion volume was (512.31±104.76) vs(683.25±113.52)mL, and the onset time of hemostasis was (14.63±3.18) vs (21.72±5.29) min (P0.05). At 24 h postpartum, NE, Cor, SOD and MDA were higher than those before delivery in both groups, but the observation group was lower than the control group (P<0.05); TT, APTT and PT were longer and Fib was lower in both groups than before delivery, but TT, APTT and PT were shorter and Fib was higher in the observation group than in the control group (P<0.05); CRP, IL-8 and TNF-α were higher in both groups than before delivery, but the observation group was lower than in the control group (P<0.05). 【Conclusion】 Hemostasis in patients with refractory postpartum hemorrhage treated with recombinant human coagulation factor Ⅶa combined with Bakri balloon compression was effective, which can improve coagulation, reduce transfusion, decrease oxidative stress injury and inflammatory response without increasing adverse effects.
ABSTRACT
Objective:To explore the significance of coagulation and platelet function analysis (Sonoclot) in monitoring coagulation function, severity evaluation and blood transfusion indication of perioperative liver transplant (LT) recipients.Methods:A total of 95 perioperative LT recipients received Sonoclot, thromboelastography (TEG), routine coagulation panel, liver function panel, blood routine, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scoring and model for end-stage liver disease (MELD) scoring between January 2021 and October 2022.The correlation analysis of the above parameters was performed.According to the scores of APACHE Ⅱ and MELD, they were assigned into three groups of low-risk, medium-risk and high-risk.The levels of Sonoclot parameters in each group were compared.They were divided into two groups of transfusion (n=31) and non-transfusion (n=64) according to the necessity or non-necessity of transfusion..The risk factors for blood transfusion were examined by Logistic regression and receiver operating characteristic (ROC) curve.Results:Pearson's correlation analysis indicated that activated clotting time (ACT) value was correlated positively with the levels of prothrombin time (PT), prothrombin time ratio (PTR), international standard ratio (INR), R/K value, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactic dehydrogenase (LDH)( r=0.279 1, P=0.006 2; r=0.280 2, P=0.006 5; r=0.3, P=0.003 5; r=0.642 8, P<0.000 1; r=0.452 8, P<0.000 1; r=0.377 6, P=0.002; r=0.349 6, P=0.000 6; r=0.271 4, P=0.018 3) and yet negatively with the levels of platelet (PLT), MA, CI and α ( r=-0.339 1, P=0.000 8; r=-0.573 3, P<0.000 1; r=-0.656 3, P<0.000 1; r=-0.632 6, P<0.000 1); CR value was correlated positively with the levels of maximal amplitude (MA), coagulation index (CI), α and ALT ( r=0.466 8, P=0.000 6; r=0.482 7, P=0.000 4; r=0.514 8, P=0.000 1; r=0.229 2, P=0.027 1) and yet negatively with the level of R/K value ( r=-0.366 9, P=0.010 3; r=-0.356 9, P=0.011 0); platelet function (PF) value was correlated positively with the levels of PLT, MA, CI, α and alkaline phosphatase (ALP)( r=0.481 9, P<0.000 1; r=0.630 7, P<0.000 1; r=0.623 5, P<0.000 1; r=0.593 0, P<0.000 1; r=0.223 1, P=0.032 5) and yet negatively with the level of R/K value ( r=-0.421 5, P=0.002 8; r=-0.530 7, P<0.000 1). CR value was correlated negatively with APACHE Ⅱ score ( r=-0.212 3, P=0.038 9) while ACT value was correlated positively with MELD score ( r=0.244, P=0.04). ACT values spiked in low, middle and high-risk groups of APACHE Ⅱ and MELD scores while PF value declined gradually by grouping these recipients based upon scoring systems.CR values decreased merely in MELD score.Logistic regression analysis indicated that ACT was a risk factor for necessity of blood transfusion in perioperative LT recipients ( OR=1.010, 95% CI 1.000-1.019, P<0.05). The maximal area under the curve of ROC curve analysis plus ACT, hemoglobin (Hb) and hematocrit (Hct) was 0.896. Conclusions:Sonoclot parameters of perioperative LT recipients have some certain correlation with thromboelastographic and conventional coagulation parameters.Both may serve as a supplementary means.Associated with liver function parameters and liver scores, Sonoclot parameters are significant for early clinical evaluations.Sonoclot parameters plus Hb/Hct detection have some guiding significance for perioperative LT recipients with necessity for blood transfusion and blood products.

Conclusions:The elderly patients with COPD have obvious inflammatory reaction, abnormal coagulation function and decreased immune function. With the progress of the disease, the inflammatory reaction, abnormal coagulation function and decreased immune function are more obvious.
ABSTRACT
Objective:To compare the value of difference between thromboelastogram (TEG), coagulation function and mean platelet volume (MPV)/platelet count (PLT) ratio in sepsis patients with short-term prognosis.Methods:A total of 271 patients with sepsis admitted to the Affiliated Hospital of Xuzhou Medical University from January 2020 to September 2021 were retrospectively analyzed. The clinical data of the patients were recorded, and the SOFA score and APACHE Ⅱ score were calculated. The patients were followed up within 28 days and were divided into the survival group and death group. The TEG, coagulation function and MPV/PLT ratio were compared between the two groups. The independent prognostic factors of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were confirmed by Logistic regression analysis. The combination of Angle + CI + AT-Ⅲ + D-Di +MPV/PLT ratio was established, and the ROC curve was drawn to evaluate the prognostic value of Angle, CI, AT-Ⅲ and D-Di combined with MPV/PLT ratio in patients with sepsis.Results:The mortality rate of patients with sepsis was 42.4%. The D-Di and MPV/PLT ratio of the death group were significantly higher than those of the survival group, and the differences were statistically significant. Angle, CI and AT-III in the death group were significantly lower than those in the survival group, and the differences were statistically significant. Logistic regression analysis showed that Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were independent predictors of the prognosis of patients with sepsis (all P < 0.05) . The area under the curve of the combined detection of Angle, CI, AT-Ⅲ, D-DI and MPV/PLT ratio to evaluate the prognosis of sepsis at 28 days was 0.931, which was larger than that of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio alone (0.755, 0.790, 0.776, 0.729 and 0.746). The sensitivity and specificity of the combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were 83.5% and 91.0%, which were also higher than those of the single index . Conclusions:Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio are independent prognostic predictors of patients with sepsis. The combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio has high sensitivity and specificity in evaluating the prognosis of sepsis.
ABSTRACT
Objective:To investigate the clinical application effects of leukocyte-filtered blood transfusions.Methods:A total of 120 patients with massive bleeding who received transfusions of a large amount of blood in the First People's Hospital of Yongkang, China from January 2017 to December 2018 were included in this study. They were divided into a control group (even numbers) and an observation group (odd numbers) according to registration numbers. The control group was subjected to direct blood transfusion. The observation group was given leukocyte-filtered blood transfusions. Coagulation function index, hemorheological index, cellular immune function, immunoglobulin level, body temperature, and the incidence of febrile non-hemolytic transfusion reactions were compared between the two groups.Results:After blood transfusions, prothrombin time, activated partial thromboplastin time, thrombin time in the observation group were (12.39 ± 1.41) seconds, (26.84 ± 6.47) seconds, and (14.32 ± 3.14) seconds, which were significantly shorter than those in the control group [(15.54 ± 2.03) seconds, (34.23 ± 7.59) seconds, (20.98 ± 4.27) seconds, t = 9.872, 5.740, 9.733, all P < 0.05]. Hematocrit, erythrocyte sedimentation rate, and plasma viscosity in the observation group were (39.28 ± 2.17)%, (25.97 ± 4.10) mm/h, and (2.19 ± 0.45) mp·s respectively, and those in the control group were (34.64 ± 4.52)%, (21.85 ± 3.64) mm/h, and (1.76 ± 0.42) mp·s respectively. There were significant differences in these indices between the two groups ( t = 9.87, 5.74, 9.73, all P < 0.05). There were significant differences in CD 3+, CD 4/CD 8, immunoglobulin G, immunoglobulin A, and immunoglobulin M between before and after blood transfusions in the control group ( t = 5.99, 5.91, 5.77, 5.80, 5.85, all P < 0.05). There were no significant differences in these indices between before and after blood transfusions in the observation group (all P > 0.05). After blood transfusions, body temperature was significantly lower in the observation group than in the control group [(36.58 ± 0.50) ℃ vs. (37.16±0.57)℃, t = 5.95, P < 0.05]. The incidence of febrile non-hemolytic transfusion reactions was significantly lower in the observation group than in the control group (1.67% vs. 13.33%, χ2 = 5.88, P < 0.05). Conclusion:Leukocyte-filtered blood transfusions can effectively restore the patient's body temperature to normal, improve coagulation function index and hemorheological index, reduce the impact of blood transfusions on the patient's immune function, and reduce febrile non-hemolytic transfusion reactions.
ABSTRACT
Objective:To explore the effect of postoperative intravenous drip of tranexamic acid on perioperative blood loss, coagulation function and knee joint function in patients undergoing total knee arthroplasty.Methods:A total of 100 patients who underwent unilateral total knee arthroplasty for the first time from August 2018 to August 2020 in Dingzhou People′s Hospital were selected and divided into the tranexamic acid group and the control group according to registration order, with 50 cases in each group. The tranexamic acid group was given intravenous infusion of tranexamic acid immediately after the operation, and the control group was given intravenous infusion with the same dose of normal saline after the operation. The postoperative drainage volume was evaluated at 12 h after the treatment, and the total blood loss and occult blood loss were calculated. The change value of hemoglobin, related indexes of the coagulation function at 24 h after the operation, the knee joint range of motion before and after the operation, and Hospital for Special Surgery knee score (HSS score) were recorded. The proportion of blood transfusion, the rate of deep vein thrombosis and the incidence of pulmonary embolism were compared.Results:The postoperative drainage, total blood loss and occult blood loss in the tranexamic acid group were significantly lower than those in the control group ( P<0.05). The change value of hemoglobin in the tranexamic acid group was significantly lower than that in the control group: (33.32 ± 8.87) g/L vs. (47.37 ± 9.26) g/L, t = 7.75, P<0.05. There was no statistically significant difference in related indexes of coagulation function in the two group at 24 h after the operation ( P>0.05). The range of motion of the knee joint and the HSS scores in the tranexamic acid group were significantly greater than those in the control group: (98.57 ± 7.28)° vs. (87.20 ± 8.05)°, (87.25 ± 8.30) points vs. (78.37 ± 10.20) points, t =7.41, 4.78, P<0.05. The proportion of postoperative blood transfusion, the rate of deep vein thrombosis and the incidence of pulmonary embolism in the tranexamic acid group were significantly lower than those in the control group: 14.0%(7/50) vs. 32.0%(16/50), 6.0%(3/50) vs. 20.0%(10/50), 4.0%(2/50) vs. 16.0%(8/50), χ2 = 4.57, 4.33, 4.00, P<0.05. Conclusions:Tranexamic acid can reduce perioperative bleeding in patients undergoing total knee arthroplasty, reduce the proportion of patients undergoing blood transfusion, without increasing the risk of thrombosis and pulmonary embolism complications. Besides, it doesnot affect the coagulation function, and can accelerate the recovery of knee joint function.
ABSTRACT
In the context of shortage of donor livers, split liver transplantation has achieved the goal of "one donor liver for two recipients", which effectively alleviates the shortage of donor livers and has promising development prospect. With the advancement of liver transplant techniques, split liver transplantation may yield clinical prognosis equivalent to total liver transplantation. However, perioperative management of split liver transplantation still encounters multiple challenges, with demanding techniques requirement and high-risk postoperative complications. Besides, there is a possibility of dividing one high-quality donor liver into two marginal donor livers, which will affect the development of liver transplantation. In this article, perioperative management of split liver transplantation was discussed from the perspectives of preoperative evaluation, recipient management and postoperative complication management, aiming to provide reference for promoting the development of split liver transplantation and enhancing clinical prognosis of recipients after split liver transplantation.

OBJECTIVE@#To explore the relationship between clinical features, peripheral blood cell count, coagulation function, gene mutation and hemorrhagic events and thrombotic events in essential thrombocythemia (ET), polycythemia vera (PV), and primary myelofibrosis(PMF) patients.@*METHODS@#Clinical data of 78 patients with ET, PV, and PMF who were admitted to the Second Affiliated Hospital of Chongqing Medical University between September 2019 and August 2020 were retrospectively analyzed. Information about sex, age, gene mutation, peripheral blood cell count, coagulation function, and hemorrhagic and thrombotic events was included, and the influence of these data on the occurrence of hemorrhagic and thrombotic events was estimated.@*RESULTS@#Among the 78 patients with myeloproliferative neoplasms, there were 47 cases of ET, 15 cases of PV, and 16 cases of PMF.A total of 10 patients (12.82%) experienced hemorrhagic events and 27 (34.62%) experienced thrombotic events. Male,patients aged ≥ 60 years, and patients with a JAK2V617F mutation were more likely to experience thrombotic events (P<0.05). Patients with thrombotic events had higher platelet (PLT) counts and fibrinogen (FIB) levels than patients without hemorrhagic-thrombotic events (P<0.05).White blood cell (WBC) count, red blood cell (RBC) count, hemoglobin (HGB) level, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and international normalized ratio (INR) showed no statistical difference between patients with thrombotic events and patients without hemorrhagic-thrombotic events (P>0.05). There was also no significant difference in the above-mentioned indexes between patients with hemorrhagic events and patients without hemorrhagic-thrombotic events (P>0.05). Among JAK2V617F positive myeloproliferative neoplasm patients, male patients were more likely to have thrombotic events (P<0.05), and patients with thrombotic events had higher platelet counts than those without hemorrhagic-thrombotic events (P<0.05). There was no significant difference in age, white blood cell count, red blood cell count, hemoglobin level, PT, APTT, FIB, TT or INR between patients with thrombotic events and patients without hemorrhagic-thrombotic events (P>0.05).@*CONCLUSION@#Sex, age, JAK2V617F mutation and platelet count have a certain value for predicting thrombosis in patients with myeloproliferative neoplasms.

A boy, aged 2 years and 5 months, had recurrent epistaxis, and the coagulation function examination showed that activated partial thromboplastin time (APTT) was significantly prolonged. Further laboratory examinations showed that the prolonged APTT was not immediately corrected in the APTT correction test, with positive lupus anticoagulant and low prothrombin activity. The boy was diagnosed with hypoprothrombinemia-lupus anticoagulant syndrome. The condition was improved after treatment with glucocorticoid, immunoglobulin, and vitamin K1. The boy has been followed up for 6 months, and no epistaxis was observed. Prothrombin activity returned to normal, and lupus anticoagulant remained positive. This is a relatively rare disease, and for patients with bleeding symptoms and coagulation disorders, it is recommended to perform the tests such as APTT correction test, lupus anticoagulant testing, and coagulation factor dilution test, which can improve the detection rate of this disease, so as to achieve early diagnosis, provide rational treatment in the early stage, and improve the prognosis.

Objective To evaluate the effect of coagulation function changes on the incidence of acute kidney injury (AKI) after liver transplantation. Methods Clinical data of 245 liver transplant recipients who met the inclusion and exclusion criteria were retrospectively analyzed. According to the incidence of AKI after liver transplantation, all recipients were divided into the AKI group (n=99) and non-AKI group (n=146). The incidence of AKI after liver transplantation was summarized. Perioperative parameters of the recipients were collected. The risk factors of AKI after liver transplantation were assessed by univariate and multivariate analysis. Results Among 245 recipients undergoing liver transplantation, 99 cases developed AKI after operation with an incidence rate of 40.4%. Preoperative serum creatinine levels of the recipients and the in-hospital fatality were relatively high in the AKI group (all P < 0.05). Compared with the recipients in the non-AKI group, those in the AKI group presented with significantly higher liver function parameters within postoperative 24 h, significantly decreased levels of stage Ⅱ coagulation parameters including coagulation factorsⅤ, Ⅶ, Ⅸ, Ⅹ, Ⅻ and protein S, protein C and antithrombin Ⅲ, evidently elevated prothrombin time international normalized ratio (PT-INR), remarkably increased stage Ⅲ coagulation parameters including D-dimer and fibrin degradation product (FDP) levels and considerably decreased fibrinogen (FIB) level (all P < 0.05). Thrombelastogram showed that the R value was increased, the α angle was decreased and the coagulation time was prolonged in the AKI group (all P < 0.05). Logistic regression analysis demonstrated that the increased R value of postoperative thrombelastogram [odd ratio (OR) 1.116, 95% confidence interval (CI) 1.018-1.223, P=0.019], and decreased levels of antithrombin Ⅲ (OR 0.974, 95%CI 0.955-0.993, P=0.007) were the independent risk factors of incidence of AKI after liver transplantation. Conclusions The incidence of AKI after liver transplantation is high, which is associated with the coagulation function changes of the recipients. Decreased coagulation factor activity (increased R value) and declined antithrombin Ⅲ level are the independent risk factors of AKI in liver transplantat recipients.
ABSTRACT
【Objective】 To explore the effects of massive intraoperative RBC transfusion on multiple clinical test indicators and prognosis of patients, underwent tumor surgery in order to provide evidence for rational blood transfusion and effective intervention of complications caused by massive blood transfusion in tumor patients. 【Methods】 A total of 208 patients who underwent tumor resection in our hospital from January 2019 to December 2020 and received intraoperative RBC transfusion(>10 U) were selected as the study subjects. According to the amount of blood transfusion, they were divided into group A: 10~15 U, 144 patients; Group B: >15~25 U, 48 people; Group C: >25 U, 16 people. Data of liver function, coagulation, electrolyte, platelet count and short-term prognosis were collected and compared among 3 groups before and after surgery. 【Results】 No significant difference was noticed in patient pre-operation variables including ALT (U/L), AST (U/L) and TBIL (μmol/L) among three groups recieved massive blood transfusion (P>0.05), while AST was significantly lower than that after operation (P<0.05) : 105.33±238.18 vs 113.50±185.04 vs 291.25±457.33 (P<0.05). After operation, PT (s) (14.12±2.10, 14.79±2.67 and 16.10±4.06), INR(1.25±0.20, 1.31±0.26 and 1.44±0.38) and APTT (s) (30.52±5.63, 34.57±12.80 and 34.80±10.49) extended significantly than those before operation (P<0.05), while Plt (×109/L) decreased significantly (142.32±70.07, 100.04±57.50 and 85.40±41.10)(P<0.05). After operation, serum K+ and Ca2+ decreased significantly, Na+ and Cl- increased significantly, and pH value decreased (P < 0.05). Hospital stay of group C (d) was 33.73±34.62 vs 17.74±14.83 vs 20.92±17.69 (P<0.05). The mortality rate was 2.8%(4/44) vs 6.3%(3/48) vs 18.8%(3/16)(P<0.05), and mortality rate of group C was higher than the other two groups. 【Conclusion】 Postoperative dysfunction of liver and coagulation in tumor patients may be related to intraoperative RBC transfusions and consequent acid-base imbalance and electrolyte disturbance. The more the units of RBC transfused, the more abnormal the patients' clinical indicators, also the longer the hospital stay and the worse the short-term prognosis.
ABSTRACT
【Objective】 To analyze the blood transfusion strategies in extracorporeal membrane oxygenation (ECMO) recievers in our hospital, so as to explore the clinical application and efficacy of blood transfusion in patients on ECMO. 【Methods】 Data from patients on ECMO treatment in our hospital from October 2017 to October 2021 was collected. The blood transfusion data and coagulation monitoring indexes during different ECMO modes were analyzed, and the efficacy of blood transfusion was evaluated. 【Results】 No difference in the number of blood transfusions was noticed by ECMO treatment modes.The transfusion units of red blood cells, plasma and platelets in VA mode were (28.35±14.60) U, (7 367.78±5 194.33) mL and (7.04±5.10) therapeutic volumes, which were higher than those in VV mode, i. e. (18.67±21.50) U, (4 836.67±6 640.50) mL and (3.60±7.47) therapeutic dose, respectively.In VA-ECMO mode, the Hb level and platelet count before ECMO treatment were (126.44±23.9) g/L and (223.84±67.62) × 109/L, which were significantly higher than those after treatment (91.02±21.48) g/L and (172.86±127.73)×109/L.In VV-ECMO mode, the APTT before ECMO treatment was (35.28±8.73) s, which was shorter than that after treatment (41.96±13.69) s. The levels of fibrinogen, Hb and platelet count were (3.80±1.85) g/L, (123.81±33.77) g/L and (175.72±98.91)×109/L, which were significantly higher than the levels after treatment (2.78±1.08) g/L, (92.31±17.38) g/L and (125.31±98.14)×109/L, respectively. 【Conclusion】 There are differences in the amount of blood transfusion among different modes of ECMO treatment. As blood transfusion is a necessary support to ensure ECMO treatment, the monitoring of coagulation index is conducive to reduce blood transfusion, improve the efficiency of blood transfusion and benefit to patient safety.
ABSTRACT
【Objective】 To retrospectively analyze the guiding significance and effect of thromboelogram (TEG) in the clinical use of cryoprecipitation. 【Methods】 A total of 289 patients with fibrinogen reduction, admitted to our hospital between January 2018 and December 2021, were collected. They was divided into control group (using coagulation examination and clinical feature as the transfusion criteria) and observation group (above parameters plus TEG). The TEG index in the observation group before and after transfusion and Fg, APTT, PT, and TT in 2 groups of patients before and after transfusion were monitored. The efficacy and prognosis of different blood products and cryoprecipitate were compared between 2 groups of patients.) 【Results】 The efficacy of choprecipitate transfusion was better in the observation group than the control[Fg index after transfusion (g / L) 1.92±0.92 vs 1.80±1.00, P<0.05]. And less blood products were used in observation group as compared with the control[ RBC(U) 1.93±2.69 vs 2.81±3.25 (P<0.05); FFP(mL) 667±378 vs 879±455(P<0.05)]. No differences were noticed by hospital stay between the two groups, but the prognosis in the observed group was significantly better than that in the control. 【Conclusion】 It’s scientific and reasonable to apply TEG to guide the clinical transfusion of cryoprecipitate, so as to save blood resources and improve the prognosis.
ABSTRACT
【Objective】 To compare the therapeutic effects of low molecular weight heparin sodium and sodium citrate on hemodialysis(HD) patients at high risk of bleeding. 【Method】 A total of 96 patients at high risk of bleeding on maintenance hemodialysis from May 2018 to May 2020 were enrolled and divided randomly into control group(n=48) and observation group(n=48). Patients in control group received systemic anticoagulation with heparin, and patients in observation group adopted regional citrate anticoagulation of in vitro dialyzer. The indexes of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fg), D-dimer, service time of filters and the dialysis efficiency, as well as the complication occurrences of clotting events, bleeding, metabolic alkalosis and hypocalcaemia were compared between the two groups. 【Results】 No significant difference was found in coagulation indicators (ACT, PT, Fg, APPT and D-dimer) before and after hemodialysis in observation group(P>0.05), but those in control group were prolonged significantly (P0.05). The incidence of filter clotting (0.0%), dialyzer pipeline clotting (0.0%) and bleeding (2.1%) in observation group were less than those in control group (8.3%, 6.2%, 14.6%, respectively) (P0.05). 【Conclusion】 Regional anticoagulation with citric acid in vitro is safe for patients on maintenance hemodialysis at high risk of bleeding, and can greatly prolong service time of filters, reduce bleeding and thrombocytopenia rates, bring less effects to coagulation function in vivo.
ABSTRACT
【Objective】 To study the changes of blood coagulation function of donors before and after peripheral blood stem cell(PBSC)mobilization and collection, so as to evaluate the safety of the current scheme. 【Methods】 30 donors who received PBSC mobilization and collection in Zhujiang Hospital from October 2018 to October 2020 were enrolled. After mobilization by G-CSF, the correlation between coagulation function, blood routine indexes and TEG indexes of donors was analyzed, and the influence of PBSC mobilization and collection on coagulation function of donors was evaluated. 【Results】 The TEG indexes R(min), K(min), α(°), MA(mm) and CI before and after PBSC collection were 6.12±1.18 vs 7.25±2.16, 1.98±0.41 vs 2.45±0.64, 62.82±4.98 vs 57.3±6.67, 60.93±3.26 vs 55.37±4.41, and -0.31±1.40 vs -2.32±2.18, respectively(P<0.05), suggesting that there was no risk of hypercoagulability after PBSC mobilization and collection. The peak values of WBC (×109/L), Plt (×109/L) and Hb (g/L) were 62.02, 357 and 162, respectively, which indicated that the blood routine indexes after PBSC mobilization and collection were in the safe range. After PBSC collection, the CI value of 26.7% (8/30) donors was less than -3, showing hypocoagulability. 【Conclusion】 The current mobilization and collection scheme of PBSC has little effect on the coagulation function. Most of the donors had no risk of hypercoagulability, but a few showed a trend of hypocoagulability after PBSC collection.
ABSTRACT
Objective:To investigate the efficacy of concurrent chemoradiotherapy combined with icotinib targeted therapy for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC).Methods:A total of 89 EGFR-mutated NSCLC patients who were admitted to Shanxi Province Cancer Hospital from January 2017 to January 2019 were selected and divided into control group (45 cases) and observation group (44 cases) by random number table method. The control group received cisplatin combined with docetaxel concurrent chemoradiotherapy, the observation group received cisplatin combined with docetaxel concurrent chemoradiotherapy and oral icotinib targeted therapy. The blood coagulation function, immune function and levels of tumor markers were compared between the two groups.Results:There was no statistical difference in blood coagulation function, immune function and levels of tumor markers between the two groups before treatment (all P > 0.05). After treatment, the levels of fibrinogen [(13±4) g/L vs. (16±6) g/L], D-dimer [(1.0±0.8) mg/L vs. (1.4±1.0) mg/L], squamous cell carcinoma antigen [(0.97±0.23) μg/L vs. (1.11±0.21) μg/L], carbohydrate antigen 125 [(21±7) U/ml vs. (35±11) U/ml] and carcinoembryonic antigen [(2.2±0.3) ng/ml vs. (6.0±1.1) ng/ml] in the observation group were lower than those in the control group, and the differences were statistically significant ( t values were 2.84, 2.11, 3.08, 7.40 and 23.08, all P < 0.05). After treatment, the ratios of NK cells [(18±7)% vs. (15±4)%], cytotoxic T cells [(17.2±6.1)% vs. (14.7±3.6)%] and helper T cells [(31.03±0.11)% to (25.88±0.39)%] in the observation group were higher than those in the control group, and the differences were statistically significant ( t values were -2.91, -2.59 and 2.79, all P < 0.05). Conclusions:Concurrent chemoradiotherapy combined with icotinib targeted therapy can better improve the hypercoagulable state and levels of tumor markers in patients with EGFR-mutated NSCLC than simple concurrent chemoradiotherapy, and can improve the immune function of patients, which has good therapeutic efficacy.
