目的:了解贮存式自体输血在Rh(D)阴性孕妇分娩中的实际应用情况。方法:产前1~3周采集并贮存孕妇自身血液,分娩时或分娩后回输给产妇。结果:产前45例贮存自体血的Rh(D)阴性孕妇中,有10例在分娩中或分娩后回输了自体血(未输异体血),未见不良输血反应发生,母婴状况良好,Apgar评分多为10分。另外有7例产妇除了回输自体血外,又输注了一定量的异体血。比较采血前后、回输前后、回输与未回输组以及回输自体血与回输自异体血四组血液指标变化情况,均显示差异无统计学意义(P〉0.05)。结论:贮存式自体输血在Rh(D)阴性孕妇分娩中是行之有效的输血方式,既解决了血源紧张的问题,尤其是对稀有血型患者,减少异体血的输注,又提高了输血的安全性和合理性,对母婴不会造成危险,值得推广。 相似文献

BACKGROUND AND OBJECTIVES: The aim of this study was to update previous data on the practice of autologous blood transfusion in Europe. MATERIALS AND METHODS: A questionnaire, mainly about predeposit, was distributed to each National Representative on the Council of Europe's Committee of Experts on Blood Transfusion and Haematology. Detailed replies were received from 23. RESULTS: Predeposit autologous blood units collected in 2000 amounted to 3.3% of the allogeneic units, compared with 4.2% in 1997. Predeposit collection was commonest in Italy (7.8%) and Germany (6.4%). CONCLUSIONS: Although autologous transfusion showed no sign of increase in Europe from 1997 to 2000, the need for alternatives to allogeneic transfusion is growing. Policy and practices in this field should be followed on an ongoing basis. 相似文献

Background and Objective Intraoperative autologous blood recovery during radical retro pubic prostatectomy has the potential of contamination with tumour cells. Its safety is proved by similar survival rates between allogeneic and autologous transfusion to oncology patients without standardization. Silencing of the gene encoding pi class of gluthatione-S transferase is a specific and sensitive molecular marker for prostate cancer, because it is present in more than 90% of prostate tumours. Using such tumour marker, we aimed to demonstrate that viable tumour cells could be eliminated using leucodepletion filters followed by irradiation. Materials and Methods Fifty patients with pi class of gluthatione-S transferase promoter hypermethylation in their primary prostate tumours were included in the analysis. Peripheral blood samples were collected during anaesthetic induction and recovered blood was collected throughout the surgery and then submitted to washing, leucoreduction and irradiation. Samples were analysed stepwise for the presence of promoter hypermethylation using real-time methylation-specific polymerase chain reaction. Results Positive hypermethylation was found in recovered blood (two samples), recovered and washed blood (three samples), and recovered washed and filtered blood (two samples). After filtration and irradiation of the recovered blood, this marker could not be detected in any of the cases analysed, suggesting the absence of viable tumour cells. Conclusion Even though the risk of disseminating tumour cells in prostate cancer surgery by intraoperative autologous blood recovery is not yet fully established, no tumour-specific gene amplification was found after the association of blood filtration and irradiation, suggesting a significant reduction of such risk. 相似文献

目的:比较分析2011-2012年三峡大学仁和医院临床用血情况,探讨医院用血规律和存在的问题。方法:收集近2年输血科输血管理系统统计资料,统计分析。结果:2年来共有3326例住院患者输异体血,异体用血总量11798U,用血最多的科室是外科,其次是ICU,主要成分是红细胞和血浆,其次是冷沉淀。结论:随着自体输血有序开展,异体用血总量显著下降。输血科一方面严格掌控输血指征,另一方面积极推动手术科室开展多种形式的自体输血,进一步加强异体输血和自体输血的管理,促进临床科学合理用血,降低输血风险。 相似文献

Intra‐operative blood cell salvage (IOCS) is mainly avoided in onco surgery due to the suspicion that it could increase metastasis’ risk. We simulated IOCS followed by leucodepletion: HCT116 (human colorectal cancer) cells were inoculated into packed red blood cells units, and their distribution was evaluated, step‐by‐step, by flow cytometry and immunohistochemistry. Most of HCT116 cells were lost during washing, and almost completely removed after filtration. IOCS plus leucodepletion could be of great advantage for oncological patients, where allogenic blood transfusion could influence tumour progression. 相似文献

BACKGROUND AND OBJECTIVES: Although preoperative autologous blood donation (PABD) is a widespread practice in elective orthopedic surgery, it is controversial whether this procedure avoids allogeneic blood transfusions in patients undergoing total knee arthroplasty (TKA). PATIENTS AND METHODS: We performed a retrospective study on 214 consecutive patients undergoing PABD before elective primary TKA. RESULTS: Thirty-eight patients (17.8%) were transfused with autologous red blood cells (RBC), while four of them (10.5% of those requiring transfusions, 1.9% of all patients) also received allogeneic RBC. The transfused patients were, in most cases, female and had significantly lower basal and preoperative haemoglobin levels. CONCLUSIONS: Based on the results of this study, PABD is not necessary in most patients undergoing TKA, although older female patients with low basal haemoglobin levels could benefit from a predeposit programme and/or erythropoietin support in order to reduce the risk of exposure to allogeneic blood. 相似文献

Allogeneic blood transfusion during liver resection for malignancies has been associated with an increased incidence of different types of complications: infectious complications, tumor recurrence, decreased survival. Even if there is clear evidence of transfusion-induced immunosuppression, it is difficult to demonstrate that transfusion is the only determinant factor that decisively affects the outcome. In any case there are several motivations to reduce the practice of blood transfusion. The advantages and drawbacks of different transfusion alternatives are reviewed here, emphasizing that surgeons and anesthetists who practice in centers with a high volume of liver resections, should be familiar with all the possible alternatives. 相似文献

Background and Objectives Microparticles (MPs) are small phospholipid vesicles of less than 1 µm, shed in blood flow by various cell types. These MPs are involved in several biological processes and diseases. MPs have also been detected in blood products; however, their role in transfused patients is unknown. The purpose of this study was to characterize those MPs in blood bank conditions. Materials and Methods Qualitative and quantitative experiments using flow cytometry or proteomic techniques were performed on MPs derived from erythrocytes concentrates. In order to count MPs, they were either isolated by various centrifugation procedures or counted directly in erythrocyte concentrates. Results A 20-fold increase after 50 days of storage at 4°C was observed (from 3370 ± 1180 MPs/µl at day 5 to 64 850 ± 37 800 MPs/µl at day 50). Proteomic analysis revealed changes of protein expression comparing MPs to erythrocyte membranes. Finally, the expression of Rh blood group antigens was shown on MPs generated during erythrocyte storage. Conclusions Our work provides evidence that storage of red blood cell is associated with the generation of MPs characterized by particular proteomic profiles. These results contribute to fundamental knowledge of transfused blood products. 相似文献

BACKGROUND AND OBJECTIVES Two main blood storage procedures can be used for storing red blood cells: refrigeration and freezing. Nevertheless, the efficiency of these procedures measured as the increase in haemoglobin after reinfusion compared with baseline has never been examined. The main objective was to examine which storage procedure yielded the largest increase in circulating haemoglobin after reinfusion compared to baseline. MATERIALS AND METHODS Equal volumes of blood from 15 men were withdrawn and stored either frozen or refrigerated as packed red blood cells. Serial measures of circulating haemoglobin by carbon monoxide rebreathing provided an opportunity to monitor recovery from anaemia, as well as the net increase in circulating haemoglobin after transfusion. RESULTS The post-thaw yield of haemoglobin in the bags was 72% after refrigerated storage compared with only 52% after freezing. Nevertheless, frozen storage allowed haemoglobin to fully recover before reinfusion, while the haemoglobin was 10% lower in the refrigerated group compared with baseline. After reinfusion, the haemoglobin levels were 11·5% higher than the baseline values in the group reinfused with frozen blood, while for the refrigerated group, haemoglobin levels were only 5·2% higher than baseline. CONCLUSION The relatively larger recovery from anaemia in the frozen group during storage more than compensated for the larger loss of haemoglobin during freezing and resulted in a larger net gain in haemoglobin. Based on the average 23 g per week recovery of haemoglobin, extending refrigerated storage to 7-8 weeks may yield sufficient time for patients to fully replenish harvested haemoglobin from three bags of blood without reliance on frozen storage of RBC. 相似文献
