Blood transfusion plays a vital role in emergency of accident and health care. The country blood resourece depends mainly the periodical blood seller and blood donors. The blood collection has obtained some achievement but been shortcomings. The Institute of Hematology and blood transfusion planned the strategy for selecting the blood donors.
Blood Donors

After 4 years with blood donation mobilization and blood component production, we obtain encouraging results, as following: 1. Renovation on blood donor source, from 90% of professional donor in 1993, down to 53% in 1997. 2. Blood collection volume is increased 3 times in 1997 in comparison to the collection in 1993. 3. Blood transfusion is ensured to be safer than in the past, by systemic application of screening test of HBV, HCV and HIV. Through screening, we detected thousands peoples with positive HBsAg, hundreds of positive anti HCV and anti HIV. These take an important part to ensure blood transfusion safety. 4. It is separated into 4 basic blood components, with packed red cell, platelet concentrated, frozen fresh plasma and cryoprecipitate. 5. It takes about 70% of partial blood transfusion among total blood transfused in 1997, compared to less than 10% before year’s 1994. Obviously, blood donation mobilization takes benefit not only for treatment service, but also for blood transfusion safety and people health care with high economic value.

During 5 years period(1994-1998) blood donor motivation and blood component preparation, encouraging results have been achieved: 1. Renew of blood resources with 90% of donors was professional in 1993 changed to 53% and 37% in 1997 and 1998, respectively. 2. Blood collection volume per year raised 4 times in comparing with the data in 1993 (800 litres to 2,850 litres in 1998). 3. 1,000 of donors with HBsAg(+) and 100 of donors with anti-HCV(+) and anti-HIV(-) have been excluded by screening. 4. 4 basic blood component have been prepared including red cell concentrates, platelet concentrates, fresh frozen plasma and anti haemophilia A cryoprecipitates. 5. 70% of clinical transfusion carried out with blood components and blood transfusion reaction have been decreasing. 6. Obviously, blood donor motivation gave a lot of advantage to patient treatment, blood transfusion safety, health care system with better economic effectiveness.

The volunteers have higher quality of hemoglobin than the regular donors. Hb standard for donation is 120 g/l. The volunteers have 94.9% reaching the standard but 5.1% of the regular donors. The volunteers have higher incidence of infectous diseases than the regular donors except the syphilis. It is important to do the P24-HIV to reduce the window period. The volunteers are the good donation, the humanitarian donors.

Blood and blood product used for 3 years - Whole blood: 86.10% and 84.91% of which used in operation of surgery and obstetric.- Packed red blood cell: 53.52% used of for curing hematopathy and 20.32% used for curing oncology hospital. - Platelet concentrate used for treating in clinical hematology and oncology hospital.

In this descriptive-comparative study, 480 blood donors (211 professional blood donors and 269 voluntary blood donors) were interviewed, and there were 17 deep interviewing for representatives of local authorities, women union, and health staff working in blood transfusion system in 3 provincial hospitals. The result of study is as follows: 26.1% of PBD group and 14.9% of VBD group were poor understandings about blood donation. 87.2% of PBD group giving blood for money. PBD group has been giving blood for many years. They often give their blood at many different hospitals, and the time interval between two times of blood donation of PBD group was not sufficient

Blood donation for saving the life is a humanitarian and clevated action. The people health is most valuable resource "healthy people - strong country". In Vietnam, there has been not enough of blood for the treatment. The date of blood transfusion safety (7.4) is an opportunity for mobilizing the "blood donation for the life" program.

Background: Random donor platelet concentrations (PCs) can be prepared by 2 methods: from platelet rich plasma (PRP) and from buffy coat (BC). In this study, the changes of cytological properties of the PCs prepared and stored at the different conditions were evaluated. Method: 45 samples of whole blood were divided into 3 groups: PCs-PRP stored at 22oC with shaking (n=15), PCs-BC stored at 22oC with shaking and PCs-PRP stored at 4oC without shaking. The assessment of platelet, red cell, white cell counts and hypotonic shock responses (HCR) were performed. Result: the yield of platelet separation of PRP method is higher and the leukocyte contamination is lower than those of BC method are. During storage, the platelet loss is highest in PCs-PRP stored at 4oC in comparison with PCs stored at 22oC. The HSR of PCs-PRP stored at 22oC reached the best results at 1st day and was stable up to 5th day. Conclusion: The PCs-PRP stored at 22oC showed the advantages in platelet yield, the leukocyte contamination and, also, the HSR
