摘　　要：目的机采血小板献血过程结束后,所用耗材管路中会有部分残余的血液无法完全回输给献血者导致浪费。文章旨在探索一种安全、简便的操作方法,尽可能减少献血者失血。方法随机抽取10名无偿机采血小板献血者,选用FENWAL血细胞分离机单针血小板采集程序,按照血细胞分离机操作手册进行血小板采集,在机器执行最后一步还输程序的抽吸时将空气陷阱倒立,并且在还输程序结束后将盐水管路和返血管路脱离各自的管路夹,通过重力的作用还输,对返血管路、空气陷阱、管路耗材残余血液分别进行细胞计数。结果管路耗材最终留有稀释血液(84.68±4.38) m L,其中含有相当于(42.06±4.08) m L全血中的红细胞,以及(214.37±68.09) m L全血中的白细胞。空气陷阱留有(11.98±3.27) m L[相当于(8.32±2.52) m L全血中的红细胞,以及(58.97±24.57) m L全血中的白细胞]血液;返血管路留有20m L[相当于(11.18±1.18) m L全血中的红细胞,以及(80.74±30.89) m L全血中的白细胞]血液,将空气陷阱和返血管路留有的血液通过改进操作方法还输至献血者体内。结论空气陷阱和返血管路中残留的血液可还输到献血者体内,为无偿献血事业的健康发展提供技术支持。Objective After the collection of blood donation by plateletpheresis,the residual blood in the pipeline consumables cannot be completely returned to blood donors,resulting in waste.The purpose of this article was to explore a safe and simple operation method in order to reduce the blood loss of donors as much as possible. Methods We randomly selected 10 plasmapheresis donors and adopted single-needle procedure of FENWAL blood cell separator to collect platelets in accordance with the blood cell separator operation manual.The air trap was inverted when the machine was performing suction,the last step of return procedure.The salt water pipeline and the blood return pipeline were disconnected their respective pipeline clip after the return procedure ended and the blood were returned by gravity.Cell counts were performed on the remaining blood in blood return pipeline,air trap and pipeline consumables respectively. Results In pipeline consumables,there was(84.68±4.38)mL residual dilute blood finally,containing equivalent red blood cells in(42.06±4.08)mL whole blood and white blood cells in(214.3±68.09)mL whole blood.In air trap,there was(11.98±3.27)mL blood,containing equivalent red blood cells in(8.32±2.52)mL whole blood and white blood cells in(58.97±24.57)mL whole blood.In blood return pipeline,there was 20 mL blood,containing equivalent red blood cells in(11.18±1.18)mL and white blood cells in(80.74±30.89)mL whole blood.The blood remaining in air trap and blood return pipeline was returned to donors by improved operation method. Conclusion The residual blood in air trap and return pipeline can be returned to donors,which provides technical support for the healthy development of voluntary blood donation.
