The Blood Donor, Donation Process and Technical Aspects of Blood Collection

Platelet rich plasma (PRP) has been shown to be beneficial in the treatment of bovine mastitis, with an action comparable to that of antibiotics. Autologous treatment is feasible in experimental conditions but is difficult to apply in field conditions, particularly in acute mastitis. The ideal scenario would be to have heterologous PRP stored on every farm so that it is readily available when needed. In this paper, we analysed data collected during bovine mastitis treatment with heterologous PRP produced by casual donor cows on several farms. We tried to identify parameters which might be useful to identify the most suitable cows to be used as blood donors, to obtain the highest yield of PRP. Variables considered for each animal were the age, the parity, the date of the last parturition, the season of blood collection, the site of blood collection (jugular or mammary vein) and the reproductive status e.g., pregnant or not pregnant. There were statistically significant differences for all the variables considered from the 135 blood cows, except for the blood collection season. The highest yield of PRP was associated with nonpregnancy blood collection within three months of parturition, parity 3 or 4, and blood collection from the mammary vein.

The existence and sustenance of the blood bank depends on blood donors. It is imperative that the donation experience is satisfactory for the donors. Therefore this study was carried out to determine the frequency of undesirable events experienced by the blood donor as part of donor haemovigilance. This was a retrospective descriptive study of the events that occurred amongst the blood donors of the blood bank of a tertiary institution. The blood donor incident book was reviewed for the period of six months. Negative undesirable events occurred in 2% of the donor populations, of which 45.8% could not complete the blood donation process while only 16.7% completed the blood donation process. Mild vasovagal attack occurred in 0.2% of the donor population. Undisclosed deferrable risk factors/ behaviours were identified by the phlebotomist in the bleeding room which made donors unfit for donation even though they had passed the donor screening criteria. This accounted for 20.8% of those with negative experience. Guidelines are required to identify donors that are not likely to complete donation to avoid wastage of time, blood, resources and reduce undesirable experiences.

Objectives The quality of whole blood (WB) units is influenced by many factors, starting with selection of donors and the method of blood collection. The aim of this study was to investigate the changes that occur in haematological and selected biochemical parameters in blood transferred from a feline blood donor to feline WB unit. Methods Data from 27 feline blood donations were used in this study. Cats were anaesthetised with a combination of tiletamine and zolazepam. Blood (10 ml/kg body weight to a maximum of 60 ml/cat) was collected in citrate–phosphate–dextrose–adenine (CPDA) anticoagulant. Lactated Ringer’s solution (10 ml/kg) was administered intravenously starting halfway through the donation. Haematological and selected biochemical parameters (complete blood count, free haemoglobin, % haemolysis, glucose, sodium, potassium, pH) were measured in the blood donor before donation and in the corresponding donated WB unit soon after collection. Results Significant decreases occurred between blood donor and WB unit in red blood cells (mean difference −1.06 × 1012/l; P <0.0001), haemoglobin (mean difference −1.6 g/dl; P <0.0001), haematocrit (mean difference −4.6%; P <0.0001), red cell distribution width (mean difference −0.9%; P = 0.0003), white blood cells (mean difference −2.17 × 109/l; P <0.0001), pH (mean difference −0.5; P <0.0001) and potassium (mean difference −1.4 mmol/l; P <0.0001). Significant increases occurred between blood donor and WB unit in platelets (mean difference +87.00 ×109/l; P = 0.0039), glucose (mean difference +25.42 mmol/l; P <0.0001) and sodium (mean difference +20 mmol/l; P <0.0001). Conclusions and relevance When using a blood collection protocol with intravenous fluid administration midway through the donation and a CPDA:blood ratio of 1:7, there were significant changes in both the haematological and biochemical characteristics between the blood donors and WB units. The majority of these changes may be the result of the anticoagulants used for storage. Understanding these changes may assist selection of blood donors and help prediction of the characteristics of the donated WB unit.

Safe Blood

Every year patients of various diseases need blood. Among them some need regular transfusion of blood. Hence, safe blood save life but unsafe one takes life. Ensuring regular flow of safe blood is a great challenge for the community in developing countries. Various public and private organizations are working for this purpose. Although the number of blood donor is increasing, there is still a huge gap in demand and supply of blood. A study has conducted to find out problems in getting blood donor in Bangladesh. Data have been collected from 430 respondents in different urban and rural areas of Bangladesh. Moreover, in depth interviews have conducted with hospital authority, blood donating organizations, public and private organizations and volunteers who work for various blood donating organizations. This study finds that patients need blood for delivery case (76%), surgery (55%), kidney diseases (33%), thalassemia (37%) and anemia (41%). About 48% blood seekers report that they require about 19-24 hours for managing each bag of blood. The seekers also report that they collect blood from relatives (77%), blood donating organizations (33%) and blood bank (26%). About 26% donors report that they have to pass more than 6 km for blood donation. They also spend money more than 100 taka (12%) for this purpose. Before and during blood donation, donors face several problems such as transportation problem (38%), coping with emergency case (32%), unskilled staff (29%), health related problem (15%) and lengthy cross checking process (35%). There are a number of people want to donate blood willingly. However, they can’t donate due to lack of available communication with blood seekers. Maintaining database of donors, training staffs and using technologies and machines for blood donation process can solve problems in blood donation.

Over Time

Social media have shown great potential for producing significant changes in behavior and have become the cornerstone for many public health and agency efforts. The nonprofit sector -including blood collection agencies- has adopted social media to aid their cause and reach their goals. However, despite the tremendous impact of social media on society and its promising role for donor recruitment and retention, it has been overlooked in donor research. This study therefore sought to map the social media landscape around blood donation. We showcase an inductive computational method to make sense of vast amounts of dynamic unstructured blood donation text data that exists on social media. With this method, we display what is discussed about blood donation on social media, how these topics are distributed on Facebook and Twitter, and how the prevalence of these topics changes over time. We applied structural topic modeling on 7 years of Dutch blood donation Facebook and Twitter data by the general public. We found 25 topics clustered in 6 distinct clusters. Over time, there is a substantial reduction of messages in which donors announce their donations. Topics that emphasize the positives of blood donation, including donor identity-related topics, are rising. In addition, the findings show a clear social media platform contrast. Topics related to campaigns and controversial policies were found more on Twitter and positive donation topics and topics related to the donation process more on Facebook. To make optimal use of social media for recruitment and retention campaigns and efforts, blood collection agencies should recognize the turbulent environment in which they take place. Monitoring public opinions about blood donation will help blood collection agencies make strategic choices and utilize social media more effectively.
