ABSTRACT
Abstract Introduction Plasma transfusion is a common therapeutic strategy used to lower international normalized ratio (INR) values in the non-emergent setting. However, due to lack of evidence of its efficacy, standardized guidelines for this practice have not been well established. Methods This retrospective observational cohort study analyzed 276 inpatient encounters that involved plasma transfusions focusing on change in INR values from pre- to post-transfusion, with respect to the following predictor variables: vitamin K co-administration, number of plasma units transfused, order indication and body mass index (BMI). Results The overall average change in the INR was 1.35. Patients who received vitamin K showed an average change of 2.51, while patients that did not receive vitamin K demonstrated an average change of 0.70. Increased numbers of plasma units transfused showed benefit up to three-unit orders. Greater decreases in the INR were observed for patients requiring plasma for anticoagulation reversal or active bleeding. There was no significant difference in the change in INR based on the BMI. By multivariate and regression analyses, the stepwise addition of each successive predictor variable demonstrated an increase in the shared variance in the outcome of the post-transfusion INR: the pre-transfusion INR and vitamin K co-administration alone was not significant (p= 0.45); the additional number of plasma units transfused was significant (R² = 0.13, p < 0.001), and; the subsequent additional plasma order indications (R² = 0.19, p < 0.001) and BMI (R² = 0.18, p < 0.001) were increasingly significant. Conclusion Taking into consideration the combination of multiple predictive factors may aid in a more efficient use of plasma products.

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.
ABSTRACT
BACKGROUND: Transfusion guidelines are not only essential for the optimal use of blood products, but also help reduce transfusion-related adverse reactions and improve patients' outcomes. In this hospital, a transfusion-indication data-entry program based on the national transfusion guidelines was developed and applied to the electronic medical record system in 2016. All transfusion orders, except for emergencies, have been performed using this program since then. This study analyzed the reasons for the transfusion to monitor the blood product usage and provide feedback to clinicians.

Objective To investigate the safety and efficacy of transfusion indication in patients with massive transfusion.Methods 64 patients with surgical perioperative period from December 2014 to December 2016 were selected from our hospital and randomly divided into control group and observation group.The control group adopted the standard of clinical transfusion technology (2000) in People's Republic of China Ministry of Health,and combined with the specific conditions of patients,according to the clinical experience of physicians,the level of blood transfusion Hb was determined,usually between 7-10 g/dL.The observation group was guided by blood transfusion index.The level of 24 h after operation,the flow rate after operation,the time after the operation,the time of postoperative hospitalization,the amount of infusion,the infusion rate and the incidence of complications were compared between the 2 groups.Results The Hb level of the observation group was lower than that of the control group at 24 h after operation,and the postoperative drainage volume was less than that of the control group.The time of postoperative removal was earlier than that of the control group,and the postoperative hospitalization time was shorter than that of the control group.The difference was statistically significant (P＜0.05).The infusion rate of the observation group was less than that of the control group,and the infusion rate was lower than that of the control group,and the difference was also statistically significant(P＜0.05).The incidence of complications in the observation group (3.13％) was lower than that of the control group (15.63％),but the difference was not statistically significant (P＞0.05).Conclusion:the blood transfusion indication score of the patients with large blood transfusion is obvious,and the safety is good,and it has important clinical significance.Conclusion The blood transfusion indication score of the patients with large blood transfusion is obvious,and the safety is good,and it has important clinical significance.
ABSTRACT
Background and purpose:Reasonable proportion with blood less than half of the surgical system, cancer patients during surgery prone to acute massive blood loss, this study aimed to investigate blood transfusion in the patients who diagnosed with cancer during operation in the Afifliated Tumor Hospital of Xinjiang Medical University, and in order to improve the intraoperative blood transfusion and make it more scientiifc and more reasonable.Methods:The patients who were taken selective operations and heterogenous blood transfusions in the Afifliated Tumor Hospital of Xinjiang Medical University from Oct. 2012 to Dec. 2013 were enrolled, and the clinical data were retrospectively surveyed and investigated.The intraoperative use of blood components and reasonableness in each department were analyzed.Results:The medical records of 299 blood transfusion receipts proportions of reasonable transfusion of RBC from department of gastrointestinal surgery, gynecology, orthopedics, hepatobiliary surgery, neurosurgery, urological surgery and thoracic surgery were 88.9%, 91.8%, 94.3%, 96.3%, 91.6%, 100%, 81.3%,respectively. And the proportions of reasonable transfusion of plasma were 86.2%, 71.8%, 96.4%, 78.4%, 100%, 100%, 87.5%, respectively. The proportions of low-volume blood transfusion and the combined transfusion of RBC and plasma were 62.5% and 43.2% in unreasonable blood transfusion.Conclusion:Except for the unreasonableness in very few departments, the intraoperative blood component transfusion is carried on fairly well. The medical staff still should be further trained in the appropriate use of blood and strengthened the knowledge on blood transfusion.
ABSTRACT
Objective To explore the rationality of clinical blood transfusion since the Ministry of Health enacted the The Technical Criterion of Clinic Blood Transfusion' in 2000. Methods Retrieved the literatures on the appraisal of rationality of clinic blood transfusion published in core journal between 2000 and 2010, and analyzed the rationality of clinical blood transfusion in recent 10 years. Results In 35 literatures entered, the proportion of appropriate blood transfusion of platelet was the highest compaved with the lowest proportion of plasma. the proportion of appropriate blood transfusion in operational department is higher than that in non-operational department. The primary reason of inappropriate blood transfusion is transfusion without indications. Conclusion The proportion of appropriate blood transfusion in china is low. The government should enhance the regulation of blood usage,and the public should he educated to realize the importarce of appropriote blood transfusion in order to promote it to develop healthily.
