RESUMEN
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.
RESUMEN
BACKGROUND: When it comes to wasting blood components, it usually means wastage before transfusion due to several reasons such as improvement of the patient's condition, death of the patient, delay of blood returning, etc. Yet blood components can sometimes can be wasted after a transfusion is started and this is referred as residual blood wastage. In this study, we analyzed the rate and causes of discarded blood components that are not used and the residual blood wastage in order to help reduce the rate of blood component wastage. METHODS: From January 2009 to December 2010, the number of and the reasons for discarded blood components without use and residual blood wastage were analyzed by reviewing the laboratory information system and wastage statements at Soonchunhyang University Seoul Hospital. RESULTS: The number of blood components issued during the study period was 24,001 units. Among them, the number of units discarded without use was 162 units (0.7%) and the number of units of residual blood wastage was 115 units (0.5%). Among the reasons for the discarded blood component without use, improvement of the patient's conditions ranked as 1st with 80 units (49.5%) and death of the patient ranked as 2nd with 42 units (25.9%). The biggest reason for the residual blood wastage was transfusion-related side effects with as many as 52 units (45.2%). Other than side effects, the wastage of residue from pediatric transfusion were 48 units (41.7%), followed by delay of surgery with 5 units (4.3%) and patients' refusal with 4 units (3.5%). CONCLUSION: The wastage of residue from pediatric transfusion was the second most common cause of residual blood wastage in our hospital. According to this, we should evaluate the routine use of pediatric transfusion bags and their cost-effectiveness in our hospital.
