ABSTRACT
【Objective】 To strengthen the management of transfusion adverse events, so as to reduce the occurrence of medical damage and accidents, and guarantee the safety of blood transfusion. 【Methods】 The adverse events of blood transfusion reported in our hospital from July 2016 to December 2022 were collected, the reasons were tracked, and continuous improvements were made. 【Results】 From 2016 to 2022, a total of 315 transfusion adverse events were reported, including 233(73.97%, 233/315) cases of transfusion reactions and 82(26.03%, 82/315) transfusion adverse events. There were 271 328 transfusion cases in the same period, and the incidence of transfusion reactions was 0.858 7‰(233/271 328). The number of transfusion application was 129 887, and the incidence of transfusion adverse event is 0.631 3‰(82/129 887). Sixty-eigtht(82.93%, 68/82) cases of transfusion adverse events were caused by human factors, while the other 14(17.07%, 14/82) cases were non-human factors. According to the linear regression analysis, we have concluded that the year is a significant indicator for transfusion reaction rates (P0.05). 【Conclusion】 Strengthening the management of reporting adverse events in clinical blood transfusion, monitoring the incidence, analyzing and improving different types of adverse events by management tools can reduce the medical risks of blood transfusion and help to guarantee the safety of clinical blood transfusion.
ABSTRACT
【Objective】 To investigate the profiles of RhC, c, E, and e antigens and phenotypes in 4 704 inpatients from multiple regions, i. e. Nanning, Guangzhou and Shenzhen, and provide data information for compatibility blood transfusion of Rh blood group. 【Methods】 The Rh blood group antigens were detected by microcolumn gel cards from three manufactures. If the test and the control results are inconsistent, a third-party reagent would be used, and traditional tube method for confirmation if needed. The Chi-square test and Fisher's exact test were used to analyze antigen frequency and Rh phenotypes in each region. 【Results】 Among the 4 704 inpatients, the frequency of C, c, E, and e antigen was e(91.77%)>C(85.64%)>c(49.62%)>E(41.60%), and Rh phenotypes distribution was CCee(49.40%)>CcEe(27.53%)>Ccee(8.16%)>ccEE(7.74%)>ccEe(4.89%)>CCEe(0.96%)>ccee(0.83%)>CcEE(0.47%)>CCEE(0.02%). There were significant differences in Rh blood type distribution among Nanning, Guangzhou and Shenzhen(P<0.05). Differences in Rh phenotype distribution between male and female were noticed in Shenzhen(P< 0.05), but not in Nanning or Guangzhou. 【Conclusion】 The distribution of Rh blood group in Shenzhen, Nanning and Guangzhou were significantly different from each other, therefore regional characteristics should be considered when carrying out Rh-compatible blood transfusion, so as to guarantee the security of transfusion and reduce the incidence of unexpected antibodies.
ABSTRACT
Objective To know the situation of the hepatitis C virus(HCV)infection in blood donors of Maoming City,and pro-vide the basic data for recruiting volunteer blood donors and preventing of HCV infection.Methods Blood samples were collected in Maoming blood center,and were detected by using HCV antibodies of different manufacturers and operated by different people.Du-plicate test was used to reexamine the specimens which were reactive in the initial test.Statistical analysis was performed.Results HCV prevalence of blood donors from Maoming was 0.74%.The prevalence of female was slightly higher than the male,but the difference was not statistically significant(P >0.05).The HCV prevalence of civil servant and medical personnel was relatively low-er.HCV prevalence of repeat blood donors was obviously lower than blood donors for the first time(P <0.05).Conclusion HCV prevalence of blood donors in Maoming City was in a relative low level.The risk of HCV infection in people who is younger than 35 years old and at the same time qualified to donate blood is quite low.Establish a stable volunteer blood donor group is beneficial to blood safety.It's necessary to strength the propaganda and prevention of HCV knowledge to population besides civil servant and medical personnel,which would be helpful for the control of HCV infection.
