Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Sepsis is a common and severe infectious disease, and its associated coagulation dysfunction can cause disseminated intravascular coagulation (DIC) and organ failure, leading to a significant increase in mortality. Pyroptosis is a form of programmed cell death mediated by caspase-1 in the classical pathway and caspase-4/caspase-5/caspase-11 in the non-classical pathway, along with the effector molecule gasdermin (GSDM) family. Recent studies have shown that pyroptosis plays an important role in the development of coagulation disorders in sepsis. Pyroptosis leads to the formation of cytoplasmic membrane pores, cell swelling and membrane rupture, as well as the release and enhanced activity of procoagulant contents, strongly promoting the development of systemic coagulation activation and DIC in sepsis. Therefore, exploring the role and molecular mechanisms of pyroptosis in sepsis-related coagulation disorders is of great significance for the prevention and treatment of sepsis. This article provides a review of the mechanisms involved in pyroptosis and coagulation disorders in sepsis, as well as the role and mechanisms of pyroptosis in sepsis-associated coagulation disorders to provide new ideas for sepsis related research.

Objective To study the stability of lumbar spine after transforaminal lumbar interbody fusion (TLIF) surgery combined with a novel articular process fixation system (APFS). Methods Based on the validated finite element model of L3-S1 intact segment (Model A), TLIF surgery was simulated to establish bilateral pedicle screw TLIF model (Model B), right unilateral pedicle screw TLIF model (Model C), APFS combined with right pedicle screw fixation TLIF model (Model D). The range of motion (ROM) of the lumbar spine model and stress distributions on pedicle screws, APFS and interbody fusion cages under different working conditions were observed. Results The overall ROMs of Models B, C, and D under different working conditions were comparable, which were all smaller than those of the physiological model. Compared with Models B and C, the maximum compressive stress of the right pedicle screw and the interbody fusion cage in Model D was the smallest or between Models B and C under different working conditions. Model D had the largest peak stress of APFS and right pedicle screw during anterior flexion. Conclusions APFS combined with contralateral pedicle screw fixation can be used as a novel fixation method for TLIF surgery of lumbar spine.

【Objective】 To assess the sufficient information got by the informed transfusion recipients from the consents for blood transfusion and to explore the influencing factors, so as to provide scientific evidences for patients to comprehend the consent better. 【Methods】 A cohort study using questionnaire was conducted among 198 patients who received red blood cell transfusion from April 2019 to June 2019 in a tertiary hospital. 18 options were investigated, including basic information of patients, recall of the informed consent process performed by physicians and how well they comprehend the information. SPSS 23.0 statistical software was used for data statistical processing. 【Results】 All 198 questionnaires were returned and valid (100%, 198/198). The score of 198 informed transfusion recipients was 2~9 (5.293±1.549), and the score of Internal Medicine and Surgical transfusion patients was 6.07±1.77 vs 6.07±1.77 (P<0.05). Univariate comparative analysis showed that the clinical department, age, education background, instructions, including its time and identity of instructors, before transfusion were the variables that affected the comprehension of informed patients (P<0.05). Linear regression analysis indicated that the clinical department, pre-transfusion instruction and its time were independent influencing factors on the comprehension(P<0.05). The top 3 poorly-understood items included auto-transfusion, alternative transfusion therapy and 1-year donation deferral after blood transfusion. 【Conclusion】 More efforts are needed to help transfusion candidates to comprehend consent for blood transfusion better since their knowledge varied with clinical departments. Physicians′ transfusion knowledge and communication skills also need to be enhanced to provide targeted and multi-form informing methods.

【Objective】 To pilot an informed consent audit system for clinical transfusion in a large tertiary hospital, so as to provide evidence and recommendations to improve the consent system. 【Methods】 A report table containing key items of transfusion informed consent such as transfusion risk, transfusion benefit and alternative treatment was developed in compliance with the national guidelines and regulations, and issued to a total of 206 patients with records on red blood cell transfusion from April 1 to June 30, 2019 in a tertiary hospital. 【Results】 The audit results showed that 98.06% (202/206) of transfusion informed consents were signed by patients, but only 65.05% (134/206) were signed by doctors. 31.07% did not record the reasons for transfusion, and 46.6% did not record the transfusion plan. 99.31% of the doctors participated in the audit claimed that the patients were informed of the risk of blood transfusion, but only 79.8% (158/198) patients recalled that the doctors mentioned the risk. Although 80.5% (116/198) of the patients were informed of alternative treatment, only 28.79% (57/198) recalled being told about alternative treatment. Allogeneic blood transfusion was the most frequently choice for patients recommended by doctors, accounting for 98.61% (142/144). However, only 48.99% (97/198) of patients could recall allogeneic blood transfusion. 80.5% of the patients recalled being informed of alternative treatment plans, and only 28.79% of the patients recalled being offered alternative treatment plans. Only 43.43% of the patients considered themselves as the main participants in decision-making of blood transfusion. In terms of training, 82.64% (119/144) doctors described having attended training programs. 【Conclusion】 The written consents for blood transfusion in our hospital were not well recorded. Patients received less information of blood transfusion informed by the doctors and did not fully participant in the decision-making of blood transfusion. There is a gap between the practice and the current national guidelines and regulations. The audit results indicated that it is necessary to further strengthen the professional knowledge of clinicians and communication skills between the doctors and patients. This audit results in this study will provide recommendations for further transfusion informed consent audit and continuous improvement of clinical transfusion informed consent practice in China in the future.

【Objective】 A framework to support nurses and midwives making the clinical decision and providing the written instruction for blood transfusion has been developed and implemented in the United Kingdom as a response to the changing needs of the patient and in recognition that blood transfusion services to patients could be improved by using the untapped knowledge and expertise of experienced nurses and midwives.Special education and training program for this role development are provided jointly by the national blood and nurse management authority, higher education institutions and transfusion societies.The British government has issued and implemented a compulsory professional indemnity which cover nurses and midwives as well.The development and implementation of the framework, policies and procedures for this role development is based on the regulatory compliance and the collaboration of, and beneficial to the multiple stakeholders, with the gaps left by doctors being fillled, work load of doctors reduced, nurses and midwives achieving professional development, hospitals performing more efficiently, and most importantly, the patients having a better transfusion services.At present, there is no similar policy or program for nurses and midwives in China.Therefore, this paper introduces the policy framework and implementation for this role development in UK, which would be a valuable reference for the role development and extension of nurses and the organization, education and training for transfusion professional teams as well in China in the near future.

Blood transfusion is an important resuscitation method for combat casualties with severe hemorrhagic shock.The optimal resuscitation plan directly influences the treatment effect of the wounded.Whole blood,once the main resuscitation fluid,was replaced by blood components for various reasons and became a supplement when there was insufficient blood components supply.With the latest evidence of whole blood application in combat casualties,the development of blood transfusion technology and the deepened clinical and basic research,we realize that the obstacles in the use of whole blood are not insurmountable and that whole blood has the advantages that blood components do not have in the treatment of combat casualties.Therefore,whole blood has once again become a research hotspot in the field of combat casualties treatment.This article reviews the development history,advantages and disadvantages of whole blood application in the resuscitation of hemorrhagic shock after combat casualties,with a view to provide reference for further clinical and basic research.
