RESUMEN
【Objective】 To retrospectively analyze the reasons of insufficient blood collected, to provide evidences for further taking targeted measures, to reduce the discard of insufficient whole blood and prevent the loss of blood donors. 【Methods】 Calculate the total number of whole blood donors and the number of whole blood donors donating insufficient blood during 2018~2020 annually in Guangzhou Blood Center Information System, and the data was analyzed in SPSS (22.0) software for χ2test and linear trend test. 【Results】 During 2018~2020, the incidence of insufficient blood collected was 0.066 4%(531/799 439), and the incidence of insufficient blood collected because of poor blood flow, needle-sickness and other reasons were 0.048 7%(389/799 439), 0.010 6%(85/799 439) and 0.007 1%(57/799 439). Furthermore, the incidence of insufficient blood collected of the three above reasons had statistically significant difference between the years respectively (P<0.05), meanwhile the incidence of insufficient blood collected because of poor blood flow was in a general rising trend significantly (0.036 3%<0.038 2%<0.072 7%, P<0.05). 【Conclusion】 The incidence of insufficient blood collected because of poor blood flow was in the rising trend and further precautions should be considered. Under the normalization of the novel corona-virus pneumonia (COVID-19), the professional knowledge of epidemic prevention and control should be learned and trained, in addition the puncture technique, the ability of offering psychological care and dealing with adverse events during blood collection should be also improved among nurses continually, so as to provide high quality services for blood donors.
RESUMEN
Background: Vasovagal responses associated with acupuncture therapy are relatively uncommon adverse events, occurring in â¼0.02%-7% of treatments. The complex neurocardiovascular reflexes involved in vasovagal responses can induce a range of symptoms such as dizziness, nausea, sweating, bradycardia, hypotension, and, in some cases, syncope or convulsions. Although patients typically recover quickly with proper support, these events may be of concern and anxiety-producing for both patient and provider. Providers need to be well-versed in methods for prevention and treatment of acupuncture-associated vasovagal responses to promote safe practice environments, patient satisfaction and comfort, and cost-effectiveness. Objectives: To examine the biomedical and Traditional Chinese Medicine mechanisms of vasovagal responses, propose updated terminology, and outline steps for prevention and treatment. Methods: During an 18-month period, 281 community-style acupuncture treatments were performed on family members of admitted patients and hospital staff members at the University of Minnesota Masonic Children's Hospital. Five (1.8%) treatments resulted in documented acupuncture-associated vasovagal response (AAVR) symptoms. Results: All 5 patients recovered from their AAVR symptoms after treatment interventions. After recovery, 3 patients reported reductions in their main complaint symptoms; main complaint symptom outcomes were not recorded for the other 2 patients. Conclusions: As integrative practices become more prevalent in academic institutions and primary care environments, clear communication about, as well as prevention treatment, documentation and reporting of acupuncture-associated adverse events will become increasingly valuable. The authors recommend that clinicians in integrative practice clinical environments consider developing formal AAVR response plans as well as training students, supervising and attending providers, and ancillary staff members to ensure rapid, prepared handling and documentation of AAVR incidents.
