Objective To investigate the effects of component blood transfusion combined with heparin therapy on coagulation function and clinical outcomes in pregnant women with acute disseminated intravascular coagulation (DIC). Methods A retrospective analysis was conducted on the clinical data of 65 pregnant women with acute DIC who were treated in Obstetrics Department of Luzhou People’ s Hospital between March 2020 and March 2022. Pregnant women treated with component blood transfusion were included in the control group, while those treated with component blood transfusion combined with heparin were included in the observation group. Before and after treatment, the DIC scoring system was used for score evaluation. Coagulation function indicators and routine blood indicators were compared between the two groups of pregnant women. Adverse clinical outcomes and adverse reactions were observed in both groups of pregnant women. Results The study enrolled 65 pregnant women, comprising 30 in the observation group and 35 in the control group. Before treatment, there was no statistical difference in DIC score, coagulation function indicators, or routine blood indicators between the two groups (P>0.05). After treatment, the DIC score, prothrombin time, activated partial thromboplastin time, thrombin time, and D-dimer significantly decreased in both groups (P<0.05), and the above indicators in the observation group [3.39±0.48, (13.28±2.28) s, (24.68±2.06) s, (14.27±1.82) s, and (2.23±0.88) mg/L, respectively] were lower than those in the control group [4.11±1.56, (15.02±2.45) s, (26.79±3.18) s, (15.61±1.91) s, and (2.87±0.74) mg/L, respectively] (P<0.05). The levels of fibrinogen, platelet count, hemoglobin, and hematocrit significantly increased in both groups (P<0.05), and the levels in the observation group [(4.29±1.05) g/L, (175.36±20.46)×109/L, (84.09±7.27) g/L, and (25.49±3.13)%, respectively] were higher than those in the control group [(3.44±1.27) g/L, (145.77±21.12)×109/L, (76.58±7.13) g/L, and (23.03±3.05)%, respectively] (P<0.05). The observation group had a lower incidence rate of adverse clinical outcomes compared to the control group (33.3% vs. 74.3%, P<0.05). The incidence rates of adverse reactions were not statistically different between the two groups (P>0.05). Conclusions Component blood transfusion combined with heparin therapy for pregnant women with acute DIC can effectively improve their coagulation function, reduce the risk of bleeding, and further improve adverse clinical outcomes such as postpartum hemorrhage and hysterectomy. Additionally, this treatment approach demonstrates a high safety profile.
The incidence of cardiovascular disease remains high, and surgery is an important measure for the treatment of cardiovascular disease. However, cardiovascular surgery is complicated and difficult, and it is one of the departments with the highest rate of allogeneic blood transfusion. Allogeneic blood transfusion significantly increases the complications and mortality of patients, while autologous blood transfusion can effectively reduce allogeneic blood transfusion and adverse reactions. Autologous plateletpheresis technology is a popular autotransfusion method in recent years. This article reviews the autologous plateletpheresis technology and its clinical application in cardiovascular surgery.

ObjectiveTo explore risk factors of blood transfusion during liver transplantation and construct its prediction model. MethodsThe patients underwent liver transplantation who met the inclusion and exclusion criteria of this study from March 2020 to December 2020 in the Beijing Youan Hospital of Capital Medical University were retrospectively collected. The univariate and logistic multivariate analysis were used to evaluate the risk factors of blood transfusion during liver transplantation and construct the prediction model for intraoperative blood transfusion. ResultsA total of 151 eligible liver transplantation patients were collected in this study, including 51 non-transfusion patients and 100 transfusion patients. The univariate analysis results showed that the differences of primary diagnosis, preoperative hemoglobin (Hb), platelet count, prothrombin time, international normalized ratio, Child-Turcotte-Pugh score, and end-stage liver disease (MELD) score were statistically different between them (P<0.05). The above variables selected by the univariate analysis were selected by stepwise method, then the preoperative Hb and MELD score were selected into the multivariate logistic regression analysis, the results showed that the preoperative Hb≤113 g/L and MELD score ＞14 increased the risk of blood transfusion during liver transplantation [Hb: OR=6.652, 95%CI (2.282, 19.392), P<0.001; MELD score: OR=16.037, 95%CI (6.336, 40.592), P<0.001]. The logistic regression model predicted the area under receiver operating characteristic curve was 0.873 [95%CI (0.808, 0.919), P<0.001], the sensitivity and specificity were 91.0% and 67.5%, respectively, Youden index was 0.674, the accuracy was 86.1%. ConclusionsResults of this study suggest that preoperative Hb ≤113 g/L and MELD score＞14 increase risk of blood transfusion during liver transplantation. Logistic regression model constructed according to preoperative Hb and MELD score has a better sensitivity and specificity of intraoperative blood transfusion.
ObjectivesTo systematically review the efficacy and safety of tranexamic acid (TXA) in reducing blood transfusion and total blood loss in patients undergoing orthopaedic trauma surgery.MethodsA systematic literature search was performed using PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases. A search for grey literature was also performed in American Academy of Orthopaedic Surgeons (AAOS) and Orthopaedic Trauma Association (OTA). The search time was up to June 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias, then meta-analysis was performed by using RevMan 5.3 and Stata 14.0 softwares.ResultsA total of 10 studies were included, including 936 patients. The pooled results indicated that TXA group was superior to the control group in blood transfusion (RR=0.75, 95%CI 0.63 to 0.89, P=0.001), the total blood loss (MD=–157.61, 95%CI –250.09 to –65.13, P=0.000 8) and the wound complications (RR=0.24, 95%CI 0.10 to 0.58, P=0.002). There was no significant difference in risk of thromboembolic events (RR=1.25, 95%CI 0.78 to 2.00, P=0.36) and the mortality (RR=0.81, 95%CI 0.40 to 1.66, P=0.57) between TXA and control group.ConclusionsTXA can effectively reduce blood transfusion, total blood loss and wound complications in patients undergoing orthopedic trauma surgery. Furthermore, TXA does not significantly increase the incidence of thromboembolic events and mortality. Due to the limited quality of included studies, more high quality studies are required to verify the above conclusions.
ObjectiveTo study the expression of cytokine-induced neutrophil chemoattractant-1(CINC-1)in rats with transfusion-related acute lung injury(TRALI),explore its possible role in the pathogenesis of TRALI. MethodsSixty Sprague-Dawley rats were randomly divided into a normal control group with sham operation,a positive control group with ALI induced by intravenous infusion of lipopolysaccharide(5 mg/kg),and a TRALI group treated by intraperitoneal injection of LPS 2h before the transfusion of human plasma (1mL),a LPS control group treated by intraperitoneal injection of LPS 2h before the transfusion of normal saline(1mL).The reverse transcription-polymerase chain (RT-PCR)was used to detect CINC-1 mRNA.The level of CINC-1 in lung tissue homogenate was measured by ELISA.Morphological changes of the lung tissue were observed under light microscope.Myeloperoxidase (MPO)in lung homogenate and wet lung weight to dry lung weight ratio (W/D)were observed.The number of cells and the percentage of polymorphonuclear neutrophil (PMN)in Bronchoalveolar lavage fluid (BALF)were also compared. ResultsCompared with the normal control group and the LPS control group,the expression of CINC-1 protein and CINC-1 mRNA were increased significantly in lung of the positive control group and the TRALI group(P<0.05).The number of cells and the percentage of PMN in BALF of the TRALI group [(310.63±76.67)×106/L and (33.57±11.51)%] were significantly higher than those in BALF of the normal control group [(101.36±63.83)×106/L and (9.87±3.56)%](P<0.05).Tissue water content and MPO activity in the TRALI group were significantly higher than those in the normal control group (P<0.05). ConclusionExpression of CINC-1 protein and CINC-1 mRNA are increased in the rat lung with TRALI and PMN infiltration in lung tissue,which suggests CINC-1 participate in the process of the PMN and endothelial cell adhesion and may play an important role in the pathogeneses of TRALI.
