Effect of rapid infusion of dewhite red blood cells under different pressures on red blood cells and blood quality
Objective To investigate the effect of rapid infusion of dewhite red blood cells under different pressure on red blood cells and blood quality.Methods Four bags of 400 mL white removed red blood cells were included in the selected blood bank from January 2021 to December 2022,and each bag was evenly divided into four small bags.Different types of needles(18 G,20 G,22 G,24 G)were used and different pressures(0 mmHg,100 mmHg,200 mmHg,300 mmHg)were applied to each blood bag for rapid infusion.The flow rate of different types of needles under different pressure and the influence on RBC count and blood quality were compared.The abnormal morphology of red blood cells before and after blood flow through the indwelling needle was observed with a 20 G needle as an example.Results Under the same infusion pressure,the blood flow rate decreased with the increase of needle type,while under the same infusion pressure,the blood flow rate increased with the increase of infusion pressure,and the differences were statistically significant(P<0.05).There were no significant differences in RBC,hematocrit(HCT),hemoglobin(HGB)and platelet(PLT)before and after infusion with different needle types(P>0.05).There was no significant difference in RBC,HCT,HGB and PLT before and after infusion under different pressure(P>0.05).The number of abnormal red cell morphology increased significantly after blood flow through 20 G needle,and with the increase of infusion pressure,the difference was statistically significant(P<0.05).Conclusion In the process of rapid transfusion of white red blood cells,the increase of infusion pressure can effectively improve the infusion speed,and has no obvious effect on red blood cells and blood quality,but easily increases the risk of abnormal red blood cell morphology.
