目的 评估作者所在医院过去6年间血液制品的使用趋势。作者选用压积红细胞和血小板制品作为研究对象,因为它们的使用频率最高,所占输血机构预算较高,且最易引起输血反应。方法 从数据库中,作者选用下列参数加以研究:输血患者数,手术患者数,输血单位量,备血单位量,弃血单位量。利用这些参数建立如下参数并加以比较:输血配合率、输血单位量与输血患者数的比例、输血单位量与手术患者数的比例、以及手术患者数与输血患者数的比例。这些资料被逐年统计起来输入SPSS软件,通过偏差分析检出无效假设。结果 在过去6年间,行冠状动脉搭桥手术的患者数平
Objective To assess the trend of use of blood products in the author’s hospital over the past six years. Authors choose to use red blood cells and platelet products as the research object, because of their frequency of use, accounting for the higher blood transfusion institutions, and the most likely to cause transfusion reactions. Methods From the database, authors selected the following parameters to study: number of transfusion patients, number of surgical patients, amount of transfusion units, amount of prepared blood units, amount of bloodshed units. These parameters were used to establish and compare the following parameters: the rate of blood transfusion, the proportion of transfusion units to the number of transfusions, the ratio of transfusion units to the number of patients undergoing surgery, and the ratio of the number of transfusions to the number of transfusions. These data are collected year by year into the SPSS software to detect the null hypothesis through deviation analysis. Results In the past 6 years, the number of patients undergoing coronary artery bypass graft surgery was even
