Background: For a rapid transfusion, pressure is sometimes applied to packed red blood cells during the operation.
However, there are neither standard guidelines nor reported data regarding adequate change interval of transfusionkits. The aim of this study is to present relevant data by simulating a surgical situation.
Methods: Each unit of packed red blood cells was mixed with 50 mL of normal saline. Pressure (250 mmHg)was applied to the mixed red blood cells. Each filtration time was measured without change of the transfusionkit. The weight of the mixed red blood cells was measured before and after administration. The passed bloodwas examined microscopically for detection of possible microaggregation. Eight transfusion sets were tested with70 packed red blood cells.
Results: International guidelines have recommended replacement of the transfusion set if flow rate decreased toless than 100 mL/min. The flow rate of five transfusion sets was recorded as less than 100 mL/min. The flowrate of the third packed red blood cells decreased to less than 100 mL/min. No microaggregate was detected.
Conclusion: Therefore, we recommended replacement of the blood filter after filtering two units of packed redblood cells with pressure under operation room circumstances
