目的评价血液制剂经气动物流传输系统传送后的血液质量,为气动物流系统在医院输血科的合理应用提供理论依据从而满足临床快速高效用血要求。方法将保存10、20和30 d的红细胞悬液各20份,采用气动物流系统定向最远距离站点单次传送,比较传送前、后红细胞制品游离血红蛋白含量、血K浓度、乳酸、乳酸脱氢酶、ATP水平的变化以及电子显微镜观察红细胞形态改变;应用保存1个月、3个
Objective To evaluate the blood quality of blood products delivered by pneumatic transport system and to provide a theoretical basis for the rational application of pneumatic logistics system in the hospital blood transfusion department so as to meet the clinical requirement of rapid and efficient use of blood. Methods 20 copies of erythrocyte suspensions were stored at 10, 20, and 30 days respectively. The animals were sent to the site with the furthest distance from the aerodynamic system. The contents of free hemoglobin, blood K, lactate and lactate dehydrogenation Enzyme, ATP level changes and electron microscopy observation of red blood cell morphological changes; application save 1 month, 3
