ABSTRACT
【Objective】 To study the safety, effectiveness and nursing of blood/fluid warmer during the process of plateletpheresis in winter. 【Methods】 The blood re-transfusion speed during plateletpheresis in winter and the time of blood passing through the blood return pipeline was counted. The vitro blood was heated with a blood/fluid warmer under different temperature settings, and the rising speed of blood temperature was recorded. The blood samples were tested for blood routine examination, free Hb and erythrocyte morphology at 0, 15 and 30 minutes. In the process of plateletpheresis in winter, the blood donors′ ear temperature and the skin temperature near the reinfusion needle in the observation group and the controls were measured, and the blood donors were observed for shivering, arm chills, pain or other discomfort. After the blood donation, the thermal comfort was evaluated. 【Results】 There was no difference in the results of routine blood test and plasma free Hb test of vitro blood after warming at 41℃, 42℃ and 43℃ for 0, 15 and 30 minutes (P>0.05), and no change in erythrocyte morphology was found. The skin temperature near the reinfusion needle (before vs. after the start of phlebotomy) was statistically different by applying blood/fluid warmer or not(P0.05). The vitro blood heating experiment showed that when the room temperature was within 22~24℃, the blood retransfusion speed was (100-120) mL/min; after the application of blood/fluid warmer, the temperature of reinfusion blood could be raised from 27℃ to 33~37℃. The proportion of feeling comfortable and very comfortable and the score of thermal comfort in the blood donors who used the warmer were higher than those in the controls (P<0.05). When the temperature of the warmer was set above 38℃, the average score of thermal comfort of blood donors was above 8. 【Conclusion】 It is safe to apply the blood/fluid warmer during the plateletsapheresis in winter, which can significantly improve the comfort of blood donors and reflect the humanized service of blood stations, and is worth popularizing.
ABSTRACT
【Objective】 To analyze the demographic characteristics of whole blood donors who responded to blood donation initiatives launched by our blood center, so as to formulate an efficient recruitment strategy and provide scientific reference for solving seasonal, structural and acute blood supply tensions in this region. 【Methods】 Such characteristics as age, gender, household registration, occupation, blood type, education level, number of blood donations, blood donation location and recruitment method of 21 934 whole blood donors who responded to donation appointments issued by our blood center during January 2019 to June 2020 were analyzed, and the corresponding recruitment strategy in this region was established. 【Results】 39.79% of respondents were 36~45 years old, 69.61% were males, 70.49% were non-local permanent residents, and 62.96% were with education background from junior high school to high school. Workers accounted for 36.57%, 400 mL-donation accounted for 56.87%, the percentage of blood type O reached 42.18%, and blood donors with 2~5 donations accounted for 70.27%. The proportion of blood donors from Songshan Lake area(23.46%) ranked the highest, and that from Shuixiang area the lowest (3.26%). 76.42% of donation recruitment were issued via SMS. 【Conclusion】 Blood donors 36~45 years old, with 2~5 donations, donated 400 mL blood, non-local registered male, ordinary employees with the education level of junior high school, technical secondary school or high school should firstly be considered. The targeted areas are the Songshan Lake area, the main urban area coastal areas and southeastern Dongguan near Shenzhen.The corresponding recruitment strategies should be adjusted based on needs and emergency level.
ABSTRACT
Objective To investigate the characteristics of blood donors’psychological activity,take reasonable intervention measures to improve the success rate of blood donation recruitment and the ratio of repeated blood donation.Methods The data of blood donors’psychological activity was collected by distributing questionnaires randomly,and the psychological characteristics and worries were analysed.Results In terms of the blood donation purpose,there were 62.73% of the blood donors who donate blood for the first time and take the“utility psychological”as the principal thing.There were 76.01% of the blood donors who donate blood repeatedly and take the“dedication psychological”as the principal thing.In terms of wor-ries,there was 72.69% of the blood donors who donate blood for the first time and take the“safety of blood donation”as the principal thing.There was 77.91% of the blood donors who donate blood repeatedly and take the “service quality of blood donation”as the principal thing.Conclusion The success rate of blood donation recruitment and the ratio of repeated blood donation could be effectively improved by attaching importance to the psychological needs and worries of blood do-nors,by taking different psychological intervention measures strategies for different kinds of blood donors,and by meeting their needs and eliminating their worries.
